9/14    Does anyone else think Sun Microsystems is evil?  I have 2 biases
        #1. I went to Cal as an undergrad
        (SUN used to mean: Stanfurd University Networks)
        #2. I work for IBM.
        But seeing them fly over Dell yesterday:
        And then their advertising against Dell:
        Just is not classy. -vallard
        \- "evil" "stanford" ... come on grow up.
           if you think the ad might backfire, maybe that's worth
           talking about. i used to work for ibm too and there was a
           lot of stupidity there [dont use gnu compiler, dont talk
           about what is cool about the alpha] but in other areas
           it was a great environment and a smart company, but with
           regards to some things, they had their head up their ass.
           \_ sheesh, never hear of humor before?
        \_ do you think dell is evil for refusing to use amd? do you think
           intel is evil for refusing to let dell use amd?
           \_ Not the pp or op but Dell is evil for supporting war
              mongering, corporate tax loophole loving conservatives.
              They supported GWB and his illegal War on the Iraqi people.
        \_ I work for Sun.  And I can tell you flat out that Sun is *NOT*
           evil at all.  Sun is *STUPID*, *IRRESPONSIBLE* and has no
           accountability at the VP level and up, but they are not Evil.
           A lot of this has to do Scott McNealy's own personality.
           Instead of looking at competitor coldly and trying to figure
           out a way to crush them, he and entire Sun put a lot of emotion
           into it, and pull one prank after another (StarOffice, JDS)
           that is at most mischievous, but doesn't hurt competition in
           in any way in the long term... and a the mean time waste alot of
           its resources.
           \_ Yup as an ex-Sun employee I think you got it here.  The
              Stanford/Cal thing is just retarded - Sun was started by some
              uber-talented people, including Bill Joy from BERKELEY ...
              And Sun is no more or less evil than IBM.
           \_ Seconded. Sun is like many Frat boys I knew at Cal - too
              dumb to be dangerous or evil. - current sun employee.
        \_ Eh, the flyover stunt was pretty silly.  In this case I think
           the ads are just a necessary evil.  PHBs buy whatever has the
           buzz.  In this case their servers really are better than the
           more popular brand, and they need to show that. -jrleek
           Addendum: Ok, the ads that got "censored" are pretty low-class.
        \_ Why do people always forget about Bill Joy?
           \- "Bill Joy has a lot ot answer for." --hilfingr
           \_ Who is Bill Joy?  What does he have to answer for?
              \- He wrote the "almond" editor ... it would corrupt files and
                 was later replaced by vi.
                 \_ I've been googling and all I can find is that he wrote
                    vi, I've seen nothing about "almond."
                    \- it's been covered up. the almond editor existed long
                       before the WEEB and those of us who were around then
                       like to talk or blog about it. emacs may have an
                       almond emulation mode.
                       \_ You mean "WEB"?
                          \- NOO
              \_ In the dark and dismal corners of Cory and Evans,
                 during the dark ages (or the eighties) Bill could
                 be found hard at work on a little known and heavily
                 litigated hobby called the berkeley software
              \_ I think the "lot to answer for" may refer to vi.
              \_ I think the "lot to answer for" may refer to ALMOND. -ausman
                 \_ So, can some one give me a link on almond history?
                        \- google for "joy almond" --psb
                    \_ <DEAD><DEAD>  -tom
                        \- hint: there are much more subtle ways to say
                           something bad, and be more effective. That is, if
                           care to be less disliked. So let me try this.
                           Instead of saying "X is a moron/dumbass", say
                           "psb has failed prank and humor miserably."
                        \- google for "gabriel almond"
                 \- ALMOND was the editor for CEDAR from PARC and OAK which
                    became JAVA and ALMOND became PINE and ELM. You can google
                    for "joy gabriel almond stanford berkeley".
                 \- ALMOND was the editor for OAK which became JAVA

                    "richard gabriel almond joy".

8/9     Can anyone recommend a vendor that sells Athlon 64 X2 (dual-core)
        configurations for small businesses?  Basically it looks like we're
        buying Pentium D machines from Dell otherwise.
        \_ You want a desktop (non-buffered memory, ECC not required, etc.)
           or a workstation?  I see HP has workstations using dual-core
           Opterons.  Look for xw9300.  A bit pricy, but you get what you
           pay for.  Will see if there's something in the desktop domain.
           pay for.  Call them up and ask?
           \_ Price/performance is much better for the Pentium D than the
              dual-core Opterons.  You can heat rooms better, too.
              I'm looking for Athlon 64 X2, either the 4400+ at $630 per CPU
              or 3800+ for $405 per CPU.  Desktop.

8/5     I remember when we had 8Mb homedir quotas, and we liked it.
        \_ You probably can get an 8 MB quota again if you really want.
        \_ I remember working on a product where the whole OS, apps (word
           processor, spreadsheet, graphic, browser, e-mail, news, games...),
           templates, help files, sound files, etc. fit in 15MB disk space

7/21    I'd like to buy 10-20 heat sinks in arbitrary shapes. CPU heat sinks
        are OK, but they always sell them with a crappy fan. Anyone know
        where I can get custom sized heat sinks, or CPU heat sinks without
        fans? ok thx.
        \_ There's a store called Wierd Stuff in Cupertino or Santa Clara or
           somesuch which sells all kinds of old/salvaged/strange computer
           and electronics parts.  You can probably get a bunch of random
           heatsinks for cheap.
           \_ It's "weird."  Of course, they knew people can't spell worth
              %(*#& to save their lives, so they used to own,
              too.  I don't know if they still do.  Anyway, also try
    , another surplus store.  They have all kinds of
              heatsinks, or stuff with heatsinks on it that you can break
              %(*#& to save their lives, so they also bought
              I don't know if it's sad or funny.

        \_ What a waste of funding. It's no wonder some people are
           are skeptical of the "hi-tech" work that comes out of
           media labs.
           \_ C'mon, this is cool.  I'd much rather have some dancing stuffed
              rodent than most of the obnoxious headwound-worthy ringtones
              you get on cell phones.  -John

6/22    I'm doing some performance tuing of a multithreaded application on a
        dual-Xeon with hyperthreading.  Windows reports 4 cores and counts
        1 core @ 100% as 25% CPU usage.  I realize this is a fuzzy question,
        but what's a reasonable real-world limit for CPU usage in this
        situation, since there aren't really 4 cores?  This app has a mix of
        MMX computation, unaccelerated floating-point math, bus I/O, and a
        lot of pointer dereferencing / irregular memory access patterns.
        \_ Turn off hyperthreading.
           \_ Since I currently get around 60% reported CPU usage, it would
              seem hyperthreading is helping performance about 20%, right?
              \_ The general wisdom is that hyperthreading increases GUI
                 responsiveness but decreases overall performance by 0-5%.
                 I'm sure there's an example where hyperthreading increases
                 overall performance, but I can't think of one.
              \_ Run your app with it on and off. Compare the run times.
                 \_ Just tried that.  Hyperthreading on:  200 seconds
                                      Hyperthreading off: 220 seconds
        \_ I'm doing the same with a simulation app.  It hits the memory bus
           and CPU most.  HT actually slowed our system down considerably.  A
           dual xeon gave us about 2x speed improvement.  The dual opteron did
           the same.  We're now checking a dual opteron with each package
           having dual core.  I say this as a former Intel employee who likes
           Intel--HT sucks for anything other than casual use.  Hard. -emarkp
           \_ I agree.  If yer doing simulations or anything else hardcore,
              turn off HT.  If yer doing Word and net browsing, by all means
              turn it on because it's a more pleasant user experience.
              Or wait until the Athlon dual-cores drop from $630.
              Or don't wait and get an Intel dual-core for $250 if your room is
              too cold.
        \_ OK, so aside from dissing hyperthreading, nobody has given actual
           information on what is a realistic maximum load for a 2-Xeon
           hyperthreading system. -OP
           \_ I think you should rephrase your question. What are you
              asking? What parameter(s) do you wish to change that are
              under your control? The load should be 2 at most, since
              there are 2 CPUs. Play with it and see what happens when you
              run more processes.
        \_ Do you have two dual-core CPUs with hyperthreading enabled?
           That implies eight logical CPUs.
           If you disabled hyperthreading, then you have four logical CPUs
           and four real cores.  You should get theoretical 100% usage on
           each core.  The simplest way to do this is to write a C program
           with a while (1) loop and run it four times.
           We have an old 700 MHz 4-CPU machine at work, and I can get about
           that running Linux with top.
           For one or more real-world apps that each uses multiple threads,
           it really depends on the threading implementation in each program,
           followed by how good the kernel is at handing out tasks to 4+ CPUs.
           I can easily imagine a two-thread program that uses 100% CPU on
           one CPU and 25% CPU on a second.
           \_ I have two dual-core dual processor machines with hyperthreading
              enabled ......
              \_ So each machine has one dual-core with hyperthreading?
                 Yeah, then that means four logical CPUs, two real cores,
                 per computer.
                 You can only expect a maximum of 100% CPU usage over the
                 two logical CPUs that sit on one physical core.
                 Anyways, if you run four while (1) C programs you should
                 get 200% total over the four CPUs as reported by top.
                 Same thing for Windoze if you have four CPU graphs.

6/20    I was waiting for a powerbook G5 and then come this announcement
        about a switch to intel.  Now I'll just sit tight and see what
        comes out.  Anybody else doing the same?   I'm wondering if I'll
        be able to run windows on a intel-based powerbook (so that I don't
        have to run virtualPC).  Thanks.
        \_ You will not be able to run Windows on Apple-branded hardware;
           so says Apple.  (And VirtualPC >> dual-booting anyway).  -tom
              "That doesn't preclude someone from running it on a Mac. They
              probably will," [Apple Senior Vice President Phil Schiller] said.
              "We won't do anything to preclude that."
           \_ There is nothing that prevents Microsoft from making Windows
              compatible with Apple's Intel boxes if they really wanted to.
              Of course, to run it legally, you'll have to pay the full
              price for Windows since it probably won't come with the machine.
           \_ Where did you read this?  The last thing I read said that they
              wouldn't stop anyone from running Windows on an intel mac.
           \_ How well does direct3d peform on VirtualPC?
              \_ badly.  Probably still badly when Apple switches to Intel
                 chips.  If you want to run Windows direct3d applications, get
                 a Windows box.  -tom
                 \_ So "VirtualPC >> dual-booting" means?
                    \_ Dual-booting is a major pain in the ass, no matter
                       what the two OSes are, but especially if one of them
                       is Windows.  -tom
                       \_ Intel's new line of chips is supposed to support
                          VT technology so you can run two oses and switch
                          between then without a reboot.  Should be nice
                          if it works.
        \_ I wouldn't wait if I didn't have a laptop and if I needed one NOW.
           But if you can wait and then buy one as soon as Apple comes up
           with one, the only problem that I can think of is that probably not
           all of third party commercial Mac software will be ported to Intel
           by then.
           \_ Some insider dirt: I heard that the Unreal Tournament guys got
              a working universal binary port together in about two hours.
              I'm thinking this transition will be a lot easier than 68k/PPC.
              \_ Gee, UT was an engine that was orginally ported over from
                 x86 to PPC.  Don't you think that's going to make porting
                 it back to x86 just a wee bit trivial?
        \_ You still haven't told us if/how you fixed your PC networking
           problem. You wanna share your experience?
        \_ If you want to wait for an x86 PB/iBook plan on waiting more than
           1 yr unless you are willing to deal w/ the curse of the rev 1 pb.
           Personally I'm waiting for Apple to release an iBook w/ a Quartz
           Extreme 2D compatible video card and I'm going to get that and
           hold onto it until the kinks are worked out of the x86 line. The
           reason I'm going w/ the iBook is that it is almost as light as
           the pb and is significantly cheaper.
           \_ thanks for the tip.  The reason why I've been holding out for
              a G5 PB is because I've heard that virtualPC runs very slow
              on a G4.  VirtualPC on an Intel is probably going to be a lot
              faster.  I don't play games so graphics performance is not an
              issue for me.  -op

6/8     I recently bought Via Samuel 2 based motherboard to use for my
        firewall.  There is a little fan mounted on the cpu and I was
        wondering if I could disconnect it and stick a bigger 80 mm or
        120 mm fan on top of the cpu and run the system safely. The
        current fan is a bit loud and I want to make the system as
        quiet as possible.  I'm open to other suggestions as well. tia.
        \_ Do you know exactly which processor is on your motherboard?
           Browsing the Via website, it seems that the Samuel 2 core is in
           both the low end of the Eden family and the slowest C3.  The
           Eden dissipates less than 7W, and you should just use a passive
           heatsink.  (The slowest Edens dissipate less than 5W and should no
           t even require a heatsink.)  The Samuel 2 C3 dissipates 13W and
           should require active cooling, but you can probably swap in any
           fan and it will work fine.  (By way of comparison, I have been
           running a 1GHz Celeron dissipating probably 20W fanless for 3 years
           now, and I have only had heat related failures on 3 or 4 days in
           that period.)

6/7     Why Intel? why not AMD?  They both run on notebooks(unlike the G5)
        Also, does this pave the groundwork for porting OS X to all PC
        \_ You know, you guys are trying to find good technical reasons
           for the move. I think it's actually simpler than that. Economics.
           IBM can't produce their chips cheaper than Intel, which we all
           know is kicking TI and other microprocessor fabs. IBM simply can't
           sell their chips to Apple at competitive market rate. The
           mundane technology of integration is driven by business, not
        \_ Intel has the best laptop chips and once Apple has made the
           transition it'll be easy to move to AMD if they want to.
        \_ PC BIOS is a fundamentally different architecture than the Mac.
           \_ I wonder.  Macs these days use mostly commodity hardware.
              What differences will remain?  The BIOS?  Motherboard type?
              \_ PC's have a BIOS.  Macs have real firmware. -dans
                 \_ Alas, not on Intel:
                    See "Specific Scenarios->Open Firmware" - ciyer
              \_ Each Mac will come standard with a little slice from the ego
                 of Steve Jobs.
                 \_ Which is where they get the hot air to blow out the back.
        \_ Intel has good support for DRM. (Why delete this MOTD censor?)
           \_ It does?  Cite?
        \_ Apple may not want to limit itself to x86.
        \_ Apple is trying to get away from a marginal chipset, why replace
           it with another one?
           I haven't seen enough discussion to know about the larger
           implications; will OS X be able to run on Dells?  There's a
           lot of risk for Apple either way.  -tom
        \_ In the short/mid term, Apple is unlikely to let other PC vendors
           sell OS X (of course, the hackers will make it possible). NeXT
           took about two years to solve all the driver problems that affects
           most users of generic x86 hardware and peripherals. However, moving
           to x86 would let Apple open OS X up to Dell & other select vendors
           in the future if they wanted to do so. However, not likely... one
           of Jobs' first things he did when he came back to Apple was to end
           the Clone Wars.
        \_ This is all about laptops and Athlon 64 can't compete in that
           space in the foreseeable future.  Also Apple probably wants to
           get at the pentium risc[?] core w/o the x86 microcode at some
           point in the future.
           OS X will probably never run on a non apple branded machine
           legally. While the x86 mac's will have a bios (so Windows might
           be installable on them), they will likely have a special apple
           boot rom (the dev machines supposedly have this already) which
           is needed in order to boot OS X. Unless you own an apple x86
           system you can't get a legal copy of the rom so no legal OS X
           on dells.
           The bigger question is WHY you would want to run OS X on a dell
           anyway?  Is OS X that much more compelling than Windows/Linux?
           \_ OS X is much more compelling than Windows/Linux.  And you'd
              want to run it on a Dell because Dell makes inexpensive hardware.
              I would also run it on my Sharp laptop in a second, if it were
              possible.  -tom
              \_ I run OS X on a daily basis and I still don't see why
                 it is more compelling than Windows/Linux. I agree that
                 it is nice and all but most of what I like about Macs
                 has less to do w/ OS X and a lot to do w/ the hardware:
                 ADC (w/ OSD of my monitors controls), deep sleep, power
                 on from the kbd, low noise, multiple firewire ports, &c.
                 I could easily buy a Dell but I don't b/c I can't get
                 these hardware features from any vendor other than Apple.
                 NOTE: I might not "get" it b/c I used to buy Macs for
                       purpose of running LinuxPPC b/c I liked Mac hardware
                       better than PC/Sun hardware (though the SS20 was
                       a NICE system, too bad there was no IDE support).
                 \_ Interesting. I am less enamored with Apple's hardware.
                    I do like my G4 Powerbook's sleek form factor and large
                    17" screen, though. What makes Apple interesting to me
                    again is OS X. UNIX-like and also runs applications
                    like Office and Photoshop. It's the best melding of
                    Windows and Linux. In fact, I run VMWare on a
                    Windows/Linux box to achieve the same things I get
                    with OS X. The Intel h/w is superior to Apple's, IMO.
                    I don't even care about any of the 'advantages' you
                    mentioned. --dim
           \_ Yes, it is.  However, part of its beauty is its tight
              integration with the hardware and the lack of all the misery
              generic x86 hardware and peripherals imposes on its users with
              little incompatibilities.  The "OSX on Dell" idea is kind
              of a cruel joke.

        hot and as short as Intel Pentium M based notebooks?

5/27    How is Intel's Dual-Core technology different from using two CPUs?
        \_ Difference is negligible. The point is costs. Obviously one dual
           core will cost less in the long run to make vs. 2 seperate CPUs.
           Savings may not be immediate, though.
           \_ Not always. If you have two chips with 50% yield each and decide
              to combine them into one larger die, your yield goes down to 25%.
              Your cost per area ends up increasing.
              \_ Uhm, what do you think "savings may not be immediate" means?
                 Initial runs will have a much lower yield vs. ramp-up
                 runs. Also, you forget the cost of packaging, which is
                 not insignificant for CPUs these days. Over the long term
                 the cost should theoretically be less. Also, a dual core
                 setup will not be 2x the area of a single core chip. It
                 will always be less than 2x.
                 will always be less than 2x. In addition, most likely
                 dual core will utilize a newer technology which will
                 shrink the overall size of each core.
                 \_ I'm not saying it will jump by 2x. I was just using 2x and %
                    50% yield as an unrealistic example to illustrate a point. I'm
                    just saying that increasing die area also increases cost per
                    area and that it's not as simple as throwing in the packaging
                    costs as a single overhead shared between two chips.

              \_ Exactly.  That's why som Celeron chips are simply Pentium
                 chips with half the cache disabled--that half had a flaw, so
                 they turn it off and sell the result as a Celeron.
        \_ Think about it.  I'll give you a hint - distance.
        \_ Probably not much difference.

5/18    Hyper-threading considered harmful:
                \- You mean it isn't fun and profitable?
        \_ I don't know about security problems, but lots of testing has
           led us to believe that in most instances it does not help
           performance. The number of cases it improves performance is
           small compared to the number where it degrades performance -
           especially on a multiuser machine. I always turn it off.
           \_ In my experience it helps responsiveness, at least in Windows.
              Windows 2K/XP threading just seems to work better when there are
              more than one processor.
           \_ I agree with pp.  Hyperthreading helps GUI responsiveness (Alt-
              Tabs, etc.), but does not decrease total execution time of a
              given process.  This is also the general wisdom.
              \_ Not only does not decrease, but can increase time spent
                 in CPU.
              \_ Well it *can* decrease the total time of two processes,
                 if they have certain properties.
                 \_ For most apps these days responsivenss under load is
                    a lot more important that some minor gain in raw speed.
                    I'd gladly sacrafice 1% speed (and we are really talking
                    less than that) for a noticable gain in UI responsiveness
                    when my machine is pegging.
                    \_ We are not talking about less than 1% in speed and
                       some of us actually do heavy work on our computers.
                       Depending on what you are doing, the UI response
                       might actually be *slower* because the OS thinks it
                       has 2 CPUs when it only has 1 (worse scenario is
                       when it thinks it has 4 and only has 2 and, I
                       imagine, gets worse the more CPUs you have). I suggest
                       always turning off hyperthreading.
        \_ Is the hyperthreading thing the same as bundling two CPUs together?
           I have a dual P3 machine, and it helps when my compiler compiles
           multiple modules in two parallel processes.
           \_ No.

5/16    I am looking for recommendations for a how-to-assemble-one's-own-
        computer-book. I would just buy a Dell but I want something quiet.
        The system will run XP and SuSE. -- ulysses
        \_ Buy Dell, donate to Republicans. It's as simple as that.
        \_ Is that worth it?  One standalone copy of XP is so expensive.
           \_ Worth it?  Probably not.  Fun and instructive, yes.  Also you
              don't have to pay full retail for XP. -!op
        \_ My Dell is very quiet.
           \_ My Dell is very noisy (the power supply) and the
              replacement from Dell is not much better either. I hate
              the fact that I cannot put in a standard ultra-quiet
              power supply because it won't fit Dell's propretary
              case!! I am never getting a Dell computer again.
              \_ Who sells cheap standard PCs?  Tiger Direct?
                 \_ Tiger Direct?  Only if you take their rebates into account,
                    and that might not be an entirely wise thing.

                    every few years gives me the opportunity to be
                    informed about the latest PC building trend. There
                    are tons of places that sells standard PCs.
                    \_ Care to recommend one?
              \_ My Dell dual Xeon at work is noisy, but my home machine is
                 silent.  I can't hear the fan or hard drive at all.  It was a
                 Dimension 4600.
        \_ The Dell OptiPlex GX280 (Small Business only) is reviewed by
  as very quiet, due to its new BTX case design (which
           funnels air down a central corridor as my Geek Squad friend
           tells me).
           Our office is buying them, but I'm too lazy to walk over and check
           how loud they are.  These are standard Dell Small Business desktops
           as of ~ half a year ago.  Don't get the Small Form Factor version,
           which only has 2 DIMM slots (I would get the Mini Tower).
           Don't get any Pentium 4 above 3.2 GHz.
           \_ The Precision series is pretty quiet. In spite of the above
              advice, the desktop is even quieter than the minitower.
              \_ Do you stand the Desktop on its side like in the picture?
                 How do you insert CD-ROMs?  The Precision series is a
                 "workstation" series right?
                 \_ You can stand it vertically with a plastic stand you
                    order or use it horizontally. Yes, Precision is the
                    workstation series. Like someone else noted, the Xeon
                    systems are loud. So it would be the 3x0 series which
                    is quiet.
                    \_ And the Dimension 4600's.  Just watch for

5/5     I am not familar with Solaris, so, I may be biased... My impression,
        from a desktop/laptop user point of view, is that Linux has
        better userability than Solaris10, eventhough Solaris 10 also come
        with a gnome desktop environment.  However, I find myself in a
        rare position of not knowing how to articulate this point to
        some of the Solaris fanatics.  Their argumenet is that since S10
        is also equipped with GNOME, userability is the same as Linux.
        1. is this arguement flawed?
        2. if you think Linux indeed has better usability, any concret example
           of userability is more than gnome desktop    TIA
        \_ From a user point of view, the biggest advantage of Linux is
           all the software it ships with. All of that *can* be added to
           Solaris, but it isn't there out of the box. Another advantage
           of Linux is that for most tasks the actual hardware is faster,
           assuming you are running Intel/AMD. Sun has the advantage for
           problems that fit within the larger CPU cache, but are larger
           then the (smaller) Intel cache.
        \_ No Linux desktop user has any basis for say his desktop is superior
           in usability to the S10 desktop.  This is like the dateless ugly
           girl at the dance picking on the other ugly girl for not having a

              ls, man command, to the way driver installed on S10, I
              still think Linux is friendlier.
              \_ BWWAAAAHAHAHAHA!  Man, it's 'friendlier' until you have to do
                 low down systems level programming.  Then it's 'friendly'
                 in the same way your 320lb cellmate 'Butch' is friendly.
                 \_ ^320lb cellmate^neurotic 320lb cellmate
              \_ Is that what the server world has really come down to?  One
                 version of 'ls' is "friendlier" (meaning: the way you learned
                 it on the one system) therefore that system is superior?  I'm
                 curious how many non-Linux systems you've used and for how
                 many years each.
                 \_ Your point is correct, but I've just watched (again)
                    a bunch of presentations tearing gaping new assholes in
                    Windows security.  Maybe he should have mentioned this.

        \_ What about drivers? Unless you buy hardware from Sun, you're
           going to have some serious problems with hardware support.  In
           addition, the number of binary-only desktop applications seems to be
           dwindling (for example our users would like to be able to use the
           latest Matlab and Acrobat reader but those aren't available on
           Solaris/x86). In addition, even though Sun includes Gnome, I doubt
           Solaris x86 comes with as many popular open source applications as
           there are in a typical Linux dist (but then I could be wrong, I
           haven't used Sol10 myself yet although Solaris 9 loses hands down in
           this area even though it also comes with Gnome).
           \_ Easy fix for that: just buy Sun hardware.
        \_ I don't understand the desire on the part of some people to attempt
           to compare the quality/friendliness/whatever of the desktop
           environments of what are really server systems.  If you want a nice
           GUI, buy a Mac.  If you want to play games, work in an office, and
           have the largest variety of desktop apps, buy Windows.  If you want
           a server system and you're the one making the buying deicision, the
           question is not "Is this Gnome better than that Gnome?"  The
           question you're answering and the 'debate' you've involved in is
           \_ Someone has to develop the apps for the server system and
              that lucky person often gets to use it as a desktop. It is
              true, though, that using a PC/Mac as one's desktop and
              remotely connecting to the server to code makes sense
              depending on the app being developed.
              \_ Yep, I've got the kind of luck where I have to use CDE
                 at work. As far as desktops go, Linux is easier to use
                 on x86 because there are just a lot more people using it
                 and improving it. Also, I'd have to say GNU utilities are
                 generally superior to default solaris ones.

5/2     I'm that noise intolerant guy who wanted to make my PC noiseless.
        Here is my update. In addition to changing my power supply to
        Seasonic Tornado (which is nearly inaudible at around 20db), today,
        I just received my brand new Papst 80X80mmcase fan. At $18.95 each,
        it costs 3X more and weighs 2X more than the other fans. However,
        it is only 12db and just as efficient as the other fans. It's
        amazing to hold something noiseless and totally VIBRATIONLESS to
        the touch, yet still being able to feel a huge amount of cool air
        moving through. The other fan I got is the Silentmaxx 120mm air
        intake blower (with filter). It pricey, at $22.95 each, but it
        delivers a whopping 41.2CFM at only 19.0db. Both Papst and Silentmaxx
        are import items from Germany. I'm now a big believer of quality
        German engineering. ALL HEIL DEUTSCHE TEKNIC, and fuck
        Yankee/Chinese made cheapo goods.
        \_ PABST BLUE RIBBON!!!
        \_ The standard quiet 80mm fan according to are
           specific models of the (Panasonic) Panaflo.  I got one last week,
           it's quiet and pushes medium-amount of air:
           I got the Vantec 80mm below but it clacks and is annoying:
           (probably only mine sucks - poor quality control)
           My Athlon 64 is still louder than the old Pentium 3 866 MHz, but
           I have now judged it "quiet enough" and will stop tweaking it.
           (God, I also put in a Zalman 120mm /CPU/ fan.  That thing is huge.)
           \_ Sorry, but your cheapo $5 fan is 21dB. While that is pretty
              quiet, it is not completely silent, like my superior
              GERMAN MADE fans (12dB). Each 3dB increase means 2X the sound,
              and each 6dB increase means 4X the sound. Also, try lowering
              the speed of the fan. I find that a lower speed actually cools
              the case better. The reason is that you want air flow to be
              uni-directional, and too many fans will blow hot air everywhere.
              By the way, what kind of power supply are you using? A rule
              of thumb is that they account for 1/2-2/3 of total noise.
              \_ Uh ... okay ... anyway, I have an Enermax power supply:
                 I do know the Seasonics are quieter.
                 Can you post a link to where you bought your Papst fan?
                 BTW, a 3 dB increase will increase sound POWER by 2x.
                 You need a 6 dB increase to increase sound PRESSURE by 2x.
                 Most people say you need 8-10 dB to increase perceived
                 loudness by 2x.
                 BTW, a 3 dB increase corresponds to an increase in sound POWER
                 by 2x.  A 6 dB increase corresponds to an increase in sound
                 PRESSURE by 2x.  Most people say you need 8-10 dB to increase

                 \_ I got my Papst fans from, the site German
                    John suggested. I can't find the db spec for your
                    \_ W00t!  -John
                    Enermax, although it is using 2 pretty small fans (80mm).
                    I suggest you concentrate on the noisiest thing first,
                    which is usually the power supply. Getting a power
                    supply with ONE 120mm fans means it will run at a lower
                    RPM (mine runs at 750RPM, compare that with 1500 with
                    normal fans). Noise is quadratic with RPM. After you've
                    done that, then concentrate on secondary stuff like
                    fans. Like I said, adding speed controller arrays (and
                    using a digital thermometer) really helps you cool your
                    case better AND lowering fan noise. I've done all of
                    the above and have gotten noise down to a point that
                    the only thing I hear is the humming noise of my cheapo
                    Maxtor drives and the humping noise of my neighbor 2
                    houses down. I hope to fix #1 by replacing Maxtor with
                    completely silent Seagate Barracuda in the future. I'm
                    not sure how to fix #2 though.
                    \_ Yeah, I did say the Seasonics were quieter than my
                       Enermax.  I do know the Seasonics use a big 120mm
                       fan, for lower noise.  I'll try out the Papst and
                       the Seasonic for the next computer, I think.
                  \_ Amendment: Actually, I also took out my chipset fan
                     and my VGA fan. I replaced them with big heat-sinks.
                     Taking out the VGA fan was painful (and kind of scary
                     because I had to pry open the hard thermal glue)
                     But everything worked out at the end:
                     In summary when I started the project, I had: 1 noisy
                     power, 1 loud intake, 1 loud CPU fan, 1 loud HD fan
                     1 chipset fan, and 1 VGA fan. In the end, I had:
                     1 22db Seasonic fan, 1 19db Silentmaxx intake (19db),
                     1 12db HD fan, and 1 semi-quiet (but not completely
                     silent) CPU fan.
                     \_ My Panaflo pushes 24.0 CFM of air at 21 dB(A), but
                        your Pabst pushes only 19.4 CFM at 12 dB(A).
                        Ha-ha! (according to the Excel file)
        \_ I bought the Antec Sonata case to replace my existing case
           which is too noisy. Although not completely silent, it is
           significantly quieter than my old case. The Antec power
           supply is pretty quiet, and the 120mm case fan is also
           quiet and mounted on a rubber feet connected to the case.
           The HD slot is also dampened by rubber feet, the only
           component the HD actually touches. I also replaced my noisy
           Intel CPU fan with a Zalman CPU fan, and replaced my video
           card with one that does not have a fan. Actually in my
           experience the CPU and video card fan generate quite a bit
           of noise. I could install noise absorbing padding inside
           the case, but decided it was not worth the money as the
           case currently is very quiet. Is your setup completely
           silent? (except the HD noise of course...). Silent PC is so
           nice. I hard the Mac Mini is also very very quiet, too bad
           it doesn't run XP, haha. -chiry
           \_ I also have a silent PC. It costs me $0.50 and 5 seconds to
              install. It's called a EARPLUGS. This whole conversation reminds
              me of how dumb Harley bikers go to those dumb Harley conventions
              and compare how loud their pipes are, except in a completely
              different direction.
              \_ Here's an even better idea, why don't you just perforate
                 your eardrums so that you go deaf.
              \_ Huh? earplugs? you joking right? Instead of solve the
                 problem, you cover your ears. Who said PCs should be
                 loud? Have you ever used a quiet PC? Building a quiet
                 PC is just the same as building a quiet car, a quiet
                 home, you don't solve these problems by putting in
                 ear plugs. This is the stupidest argument I've heard
                 in a while, but then again I am feeding the trolls,

        reduce? I have an AMD and I'm not sure whether the noise is from
        the CPU fan, power supply fan, gaming card fan, or the motherboard
        chipset fan. If you have those cool liquid coolers, how much did
        you spend on it and do you think its worth it?

4/15    I'm compiling something standard and it fails. Upon Googling, the
        sol'n is to use "setarch i386" on my Pentium M730 processor, and
        everything works fine. Out of curiousity, I dumped my environment
        variable under "setarch i386" and outside and they're almost
        identical. Furthermore, uname reports the EXACT same thing. I'm
        baffled now. What does setarch do?
        \_ DESCRIPTION
       setarch This utility currently only affects the output  of  uname  -m.
       For  example,  on an AMD64 system, running 'setarch i386 program' will

        \_ What's the point of running TabletPC OS if the screen is not touch-
           \_ or even if it is?
           \_ touch sensitive is good for limited applications, like GUIs that
              give you big buttons (for UPS men, census poller, voting, etc).
              Most Win apps are not like that. In addition, the selling point
              of Tablet PC is not the original PC itself, but rather, the
              ability to draw freehand (take notes, highlight EXISTING
              documents, read eBooks), and character recognition. The latter
              is especially useful for East Asian languages. I use it to
              write Chinese all the time. I still find it slow and hard to
              type Chinese, and the char recognition program is amazingly

          \_ Most Tablet PCs don't have touch-sensitive screens.  They all
             require a special stylus (and as a consequence, they're usually
             more accurate and offer other features like pressure
             sensitivity, which is good for drawing apps).  Even with a
             touch-sensitive screen, it's not like you want to smudge it up

        (between an external hard drive and my computer), which one is
        better and why? Thanks.
        \_ Firewire is faster and more robust for that application.  USB
           is more widely available if you'd ever want to move the disk to
           another machine.  -tom
        \_ Interface-wise, FireWire is better technically speaking, but to
           most users they see no difference.
           As tom said, you see USB 2.0 on more notebooks and desktops than
           FireWire, because Intel p0wnZ dat f00l st3vee j0b5, I mean,
           Intel produces mobo chipsets with USB 2.0 on-board as a std feature.
                \_ Cool, thanks for the responses.
        \_ Firewire.  It's peer-to-peer instead of host/client, so you don't
           load your CPU while transferring data.  You can burn one CD while
           ripping another one, etc.
           \_ nothing personal, but this is a fine example of the utterly

           \_ Uhm, the firewire peer to peer connectivity between computers
              has nothing to do with how efficiently peripherals functions.
              The spec has provisions for peer to peer networking which
              would allow for fast grid computing. This doesn't mean you

3/15    It's been a while since I bought a notebook. Is there any reason to
        pay extra $100 to upgrade from XP Home to XP Professional? How about
        Intel Pentium M Processor 7x5, do they run at decent speed relative
        to say, P4? And what's the difference between 1) Crystal View XGA TFT
        and 2) SXGA+ non-crystal view TFT? ok thx
        \_ You definitely want a Pentium M for the power savings.
        \_ XGA = 1024x768, SXGA = 1400x1050
           CrystalView is just the name they gave to a better LCD; don't get
           the last gen LCD
           \_ Comparing a 1024 and a 1400 IBM screen, the 1024 is brighter with
              slightly slower refresh, and the 1400 has a very wide viewing
              angle, but less brightness when viewed Head-on.
        \_ Home has problems working with more than I think 5 computers on a
           LAN and has a bunch of other esoteric cripplings that make it
           unusable by most businesses.  For home use, 'Home' is fine.
           \_ How about dialing in and running VPN to access corporate network?
              Does Home work in this case?
        \_ Clock-for-clock, 7xx Pentium Ms do more work that Pentium 4s.
           The 7xx series also use a lot less power, which means better
           battery life and cooler thighs.  Pentium M is lower voltage, lower
           frequency, bigger cache, and shorter pipeline.
        \_ Generally, multiply the Pentium M frequency by 1.5 to get the
           equivalent Pentium 4 frequency.  So a 2.0 Ghz Pentium M is like
           a 3.0 GHz Pentium 4.
           Anyway, you definitely do not want a Pentium 4 notebook.
           Runs too hot, uses too much power, notebooks are too heavy, they'll
           break from all that -- it's a desktop CPU.
           \_ Pentium 4: Desktop CPU, very hot, high power and clock rate
              Pentium 4M: Pentium 4 at lower voltage and power
              Pentium M/Centrino/7xx: Different design philosophy, very low
               power, lower clock rate but more work per cycle.
              \_ FYI, they don't make the Pentium 4 Mobile anymore
                 Also, the Pentium M not only has a different design
                 philosophy, it was engineered from the ground up as a mobile

           significant difference between Celeron M 360 and Pentium M 725?
           Besides the cache I mean.  I'm mainly interested in performance
           and battery usage.
              Celeron M's are Pentium M's with half the L2 cache and no
              SpeedStep (always runs at the list frequency).

\1/24    On 21264, you have 80 physical registers of which 31 are visible.
        However, on P4's you have 128 physical registers, of which
        8 of them are visible at one time. The rest are used for
        speculative storage and renaming (to prevent WAW and WAR hazards).
        So, why 128 physical registers when only 8 are exposed (I presume
        they're only ax-dx, and eax-edx)? Isn't that a lot?
        \_ It's been a while since I've taken 152 but I believe this has
           something to do with register renaming. Many CPUs have extremely
           deep and wide execution pipelines allowing for a massive amount
           of in-flight instructions. You cannot have 40 instructions in-
           flight, for example, with only 8 registers. When an instruction
           is issued, it is placed in a reservation station. Its regsiter
           specifier is renamed to point to other reservation stations if
           an instruction is already in-flight. When that in-flight
           instruction is completed, the reservation station for the
           pending instruction will source the write value of the instr
           that it was dependent on. Since there can be more reservation
           stations that user accessible registers, this is how we get
           the 80 physical vs 31 visible registers.
           \_ Which semester did you take 152?  I didn't learn these in Sp93.
              \_ Perhaps buy a more recent Comp Arch book (the H&P version,
                 not the P&H one). It's covered in the section on Tomasulo's
                 algorithm. This is more graduate level stuff so it's not
                 surprising that some profs don't cover it in 152.
        \_ I think by 8 exposed registers they mean eax-edx, esi, edi, esp,
        \_ The P4 is a CISC machine and does a lot for one instruction.  Hence
           the work done per instruction is higher, and hence more registers
           are necessary.  When I learned RISC programming in CS60B it was
           noted that 32 registers were available, but by convention most were
           reserved--so you only really had 8-12 registers you could really
           work with.  Also, Intel has made the L0 cache very fast so that
           there isn't much of a hit moving data from cache to register.
           \_ I respectfully disagree with the post above. CISC requires
              FEWER registers than RISC because not as many intermediate regs
              need to be kept around, and if L0 was so fast there's not
              "much of a hit" then FEWER registers would be required. Different
              codes require very different number of registers; what all the
              physical registers are used for in x86 are supporting massive
              out-of-order execution, multiple simultaneous threads, loop
              unrolling, etc. ... the existence proof is that Intel would not
              have put them there unless they helped performance.
           \_ Intel machines may be technically CISC, but they're more RISCy
              than stated above.  Most compilers write code that's very RISC-
              like.  However, since backward compatibility at every step is
              key, the Intel line has been straightjacketed into the eight-
              register world.  Fortunately (or unfortunately if you hate the
              Pentium architecture), Intel (and AMD) easily finds ways around
              that.  After 30 years shackled to the same base instructions
              I'm not quite sure why Intel doesn't build a second assembly
              language to fully leverage the architecture - having a special
              mode for this - but I guess it would be more trouble than it's
              worth to do so.

           is the technology really that cool? what did you work on?
           \_ The technology is very cool, but it has become a solution for
              a problem that doesn't exist.  The Pentium M essentially makes
              Transmeta's hardware moot.  The amount of engineering labor
              required to make code morphing really work is immense, and
              it is the kind of labor that PhDs are not fond of.  TMTA is
              staffed with lots and lots of PhDs.  I'm sure you can imagine
              the sorts of management drama that resulted from that.
              I myself worked on x86 verification, which essentially meant
              writing lots of directed tests in x86 assembly that tested
              thousands of corner cases.  In x86, virtually everything is
              a corner case due to legacy support, especially in floating
              point.  I also wrote and managed random testers.  I Learned
              A Lot, but it was Not Fun.

              I also learned that Linus Torvalds is a very nice man who drives

12/7    Followup to the hardware problem yesterday:  I down-clocked the
        FSB to 100MHz and the problem went away.  The memory went from 266->200
        the CPU went from 1466->1100, but the AGP and PCI stayed at 33MHz.
        Since memtest showed the memory itself is probably OK, and GIMPS showed
        no CPU problem, that says to me the AMD 761 Northbridge is the problem.
        Thanks to everyone who helped with this tricky problem.
        \_ No such thing as a 33MHz AGP (not commercially at least).
        \_ Did you have it overclocked in the first place???
           \_ No, it was all to spec.

                 pissed he spent ~ 2x on Corsair super-elite CL2
                 memory and had to go back to CL3 AND reduce his bus frequency.
                 This was on a Pentium 4 2.26 GHz, MSI motherboard, with
                 Intel chipset as well.
                 FYI, my Athlon 64 3200+ Newcastle with an Asus mobo and two

12/6    I'm at my wit's end with a problem.  I'm running WinXP and a lot of
        newer 3D games make the machine randomly lock hard.  There isn't much
        pattern to it, but some games do it and some don't.  This problem is
        not mentioned under tech support for the games besides the generic
        "Update your drivers and DirectX" which I've done.  Games which crash
        include Railroad Tycoon 3, Rome:Total War and Sid Meier's Pirates, and
        in the non-crash group is GTA:Vice City, Doom3, and MS Flight Sim 2004.

           turned CAS settings from Auto or CL2 to CL3 - now everything works
           \_ Some games worked and other didn't? -op
              \_ I don't think you should put too much concern on the
                 "some game work and other don't". The game that works
                 may just be not exercising the CPU enough or something.
                 I would suggest the following, download "Ultimate BootCD"
                 and try a burn-in test, if your mahcine locks up, it's BIOS
                 or hardware problem. If it passes, then maybe a software
                 problem, reinstall XP from scrach and see if it helps.
                 If it's a software problem, most likely it'll go away.
              \_ Yes.
           \_ Can you start to play some games and then they lock up,
              or will they lock up your computer on startup?
              \_ In my case they will start, then lock randomly in 1-10
                 minutes. Screen freezes and sound gets stuck in a loop.  -op
                 \_ Now's the time to upgrade to an Athlon 64 3500+ Winchester!
                    -sl0da l0s3r
                 \_ Yeah, exact same symptoms as mine. I am pretty sure you
                    are overloading your graphics subsystem. Have you installed
                    the latest firmware upgrades on both your graphics card
                    and your mother board? Could be a sound card problem
                    too, but it seems unlikely from what you have said.
                    Any kind of hardware or driver changes lately? -ausman
                        \_ Same symptoms for me too.  -ax
        \_ OK, an update for those whove been helping me:  I ran memtest86 and
           one other memory tester.  Both ran for a while reporting no errors
           until the system suddenly locked up.  I ran the mersenne prime
           torture test and had no problems.  So something is flakey, but how
           can I be sure it's the RAM, not the CPU?  My motherboard monitor
           reports in-spec temperatures and voltages both at idle and when
           running GIMPS.
           \_ Can you try a stick from another PC?
              \_ I have 2 different sticks in there now, both in use for at
                 least a year.  I'll try selectively pulling one later.  For
                 now I'm wondering about a good CPU-only stress test (like
                 one that uses only a tiny bit of memory and no mallocs() ).
                 \_ OK, I tried each stick on its own.  One crashes very
                    fast while the other takes a while.  So, either I have 2
                    bad DDR sticks, or something else is fucked.  Suggestions?
                    \_ It's your motherboard. Abit KG7s are know to be flakey.
                       Return it and get something not Abit, like a Gigabyte.
                       Abit + P4 + Via also has problems. I only recommend
                       Abit if it's the more expensive standard Intel chipset
                       version. Avoid Via chipset abits, especially if you
                       are using P4. Also, K series is known to be flakey.
                       You can try upgrading the BIOS and see if that helps,
                       but I never got one to work reliable, especially
                       on high load stuff.
                                \_ I agree with williamc, I think it's
                                   my motherboard as well, but am too lazy
                                   to change it since my disks are raided. -ax
                       \_ BIOS is current.  I'm afraid you might be right.
                          Can you reccomend a stable MB for an 266FSB Athlon?
                          \_ I'v been using a GA-7VT600 gigabyte for
                             some time now with Linux/XP and no problems.
                             It's got a KT600 and it can support up to 400
                             FSB. BTW, the reason why your MB is flakey is
                             because of the chipset combo. It's a via/amd
                             solution that just doesn't work. Avoid combo
                             solutions like this. Plus, whatever you do
                             avoid the KT266 like the plague (older
                             via chipset). Your solution was due to the
                             KT266 instability (the A version doesn't help
                             matters much, just avoid any MB like this)
                             Via cleaned up its act aver the KT266 debacle
                             and Via+Athlon is pretty stable now. Via+P4
                             is the crap, especially the P880 series.
                          \_ Motherboard having hardware issues does not
                             explain why it would lock up in some games
                             and not in others. Do you mean "flakey' in
                             some other fashion?
                             \_ Yes it does, I've seen this before on Linux
                                also. 90% of programs ran fine, even a
                                kernel recompile. But when we began to
                                load the system up with circuit simulations
                                the thing would segfault at random. It took
                                me a week of replacing parts to find out it
                                was the MB initially. What was interesting
                                was that stuff started to fail in succession.
                                First there was the segfault issue, then
                                all of a sudden kernel recompiles failed, then
                                the IDE controller went out for no reason.
                                Chipset problems usually only appear if you
                                stress the system long enough. That's why it
                                passes QA and gets put on the shelf. -williamc
                             \_ Presume that any game can lock the system by

12/1    open source sadness, SUN being destroyed by linux..
        \_ More like Sun stupidity by refusing to either
           A) Make Solaris x86 free until it was too late.
           B) Give up on the stupid "java thin client" crap
           C) Open Source Solaris and let people actually write
              drivers for 3rd party peripherals.
           D) Standardize on a PC architecture instead of dragging
              on forever with a dying USPARC platform.
           \_ Re: C), Why does it need to be open source for people to write
              drivers for 3rd party peripherals?  XP is not open source, but
              people can write drivers.
              \_ Obviously you don't understand software/hardware economics.
                 Unless your OS has a large entrenched user base (such as
                 Windows) nobody is going to spend money on writing
                 drivers for it. It's economically unsound, especially
                 if you have to buy the tools. Solaris didn't even come
                 with a free cc compiler (SunOS did). As for writing
                 drivers for XP, it costs in the neighborhood of $10,000
                 to develop a driver for it (I know, I've been involved
                 in one). Solaris needs to be open sourced so that OSS
                 people can port Linux drivers to it (which has been done
                 before) or write drivers from the ground up, especially
                 on an X86 platform. Apple's OS X would have faced the same
                 problem if it had jumped onto the X86 platform.
        \_ I am glad. I was a big, big Sun customer who kept telling my
           reps that we were going to move to Linux mostly because of cost
           since we actually prefer Solaris. Most of us don't care
           about the OS price (cheap) or whether it is open source.
           It's the Intel hardware that was much cheaper and drove the
           decision. My reps had the attitude that we were small potatoes
           since we didn't buy lots of E10Ks and that it was fine for
           client-side to be Linux as long as they could sell their
           expensive servers. Now they are paying the price for not
           listening to their customers...
           \_ Not just that--I've encountered some pretty serious
              incompetence here.  They had the chance to take a really huge
              services contract away from a major outsourcer--they threw a
              half-wit project manager and two untrained sysadmins without
              work permits at it, because "hey, we're Sun, nobody would ever
              refuse us".  -John
              \_ Sun's proposal to replace uclink was pathetic; the people

           did he accomplish at Sun?
        \_ Four sysadmins administer a 400 server webfarm, along with
           a database server, email server, all the corporate servers
           and all the networking equipment. We can do this because
           we run all Sun hardware and software. Tell me a place that

              machines is not really _that_ hard for any competent sysadmin as

           in, declare all the SA's overpaid, and replace them with Sun Service

        \_ It is more like.. if they get destroyed, it would be because of
           their own stupidity. They should have seen the Linux/x86 threat
           coming a long time ago. Granted, they're ARE embrassing Linux and
           x86 now and have plans to open source Solaris. So, it's possible
           they're not a toast yet. Though, their sales people STILL don't
           understand that the time when they could have made thousands and
           thousands of profit per machine sold are over. The other day I was

11/29   I haven't bought a PC in years.  How does the quality of Dell, Compaq
        and Gateway PCs compare?  That is, how long does a brandnew machine
        last until something breaks.  Any other major brands I missed?  I'm
        buying a low-end desktop.  Thanks for any info.
        \_ Other brands: Sony, HP, Micron (now "MPC"), eMachines.  Try CNET.
           \_ HP == Compaq, eMachines == Gateway.
              \_ They are still different "brands". i.e. at the least, the
                 cases are somewhat different at least for HP <-> Compaq.
                 Also I know the "HP" brand ones offer AMD but not sure
                 about Compaq. I have no idea what their marketing strategy
                 is though, if any. Having two brands competing in the same
                 exact market segments seems idiotic. Oh and apparently IBM
                 still produces desktop (business oriented) PCs.
        \_ You should just get a Dell if it's a desktop.  They are as good as
           anything else, and they're cheaper to configure.  All PC vendors
           use commodity hardware and re-use RMA parts, so there isn't much
           difference in reliability.  -tom
           \_ Dell uses nonstandard power supplies. If your psu fries and
              you want to replace it you're out of luck unless you hunt down
              a $20 conversion cable or spend a lot on a "real" dell PSU.
              The most standard "PC" out of the bunch is probably emachines,
              although the PSU is a micro they are still relatively easily
              obtained. Everything else (including the MB if you are so
              inclined) can easily be swapped out of these el cheapo machines.
              If you want to replace parts yourself consider
              getting a white box system from Fry's. -wiliamc
           \_ "cheaper to configure": this is not always true. There are also
              a couple other factors one might consider. One being that Dell
              has some proprietary differences for no good reason so e.g. you
              can't just go buy a power supply if the Dell one dies, you have
              to get a Dell-specific one. Another factor is others may have
              a design (case etc.) you like more. Another factor could be that
              Dell is Intel-only and this entails a price markup for the same
              \_ Typically, Dell charges about half what the other major
                 vendors do for changing RAM, disk, video cards, etc, from
                 the base models.  I've never seen an example of things
                 going the other way.  Worrying about Intel vs. AMD is
                 strictly for the slashdot crowd, to 99% of users there's
                 no difference.  -tom
                 \_ I'm saying Intel generally costs more for the same
                    performance. Do you dispute that? Worrying about changing
                    a bunch of stuff is more a Slashdot thing IMO. HP appears
                    to offer a sufficient selection of ready-to-ship versions.
         \_ I should point out there was never a "Dude, you're getting an IBM!"
            \_ But there was a "no one got fired for getting IBM" which is
               almost as bad, in a spineless corporate sort of way.
               \_ Appealing to business cowardice is kinda funny.  "Buy our
                  stuff or you might get fired!"
        \_ Thanks for all the tip so far.  I just saw the Gateway 3200S that
           has an Intel Celeron 2.66GHz.  Does anyone know roughly what clock
           rate of a Pentium 4 processor is a Celeron 2.66GHz equivalent to,
           performance-wise?  --- OP
           \_ The obvious response is "At what tasks?".  For general internet
              use it's plenty.  Probably pretty good for 3D games, but crappy
              for stuff that needs a big cache.
              \_ How about editing a huge Excel spreadsheet?  That's what my
                 wife does with my current PC.  Let's say there's a lot of RAM
                 and swapping is not a factor.  --- OP
                 \_ Just editing, you'll be fine.  Trying to do big operations
                    or computation is asking for pain.  That's just what cache
                    is best for.

10/25   What's the difference between intel's C and E cpu for p4? What about
        those processor with names like 540, 530? I am helping a friend pick
        components for a system. Any recommendations? I am thinking of
        Asus P4C800-E Deluxe with P4-3.0Ghz CPU and 1GB PC3200 memory, all for
        about $600. Is the newer socket 775 with ddr2 memory that much better?
        Not a gamer, just need a fast desktop system for general applications.
        \_ General apps means Word, surfing, and email.  This P4 system is
           already overkill.  It doesn't matter which socket, how fast the
           ram is, etc.  Get your friend to buy a mid ranged Dell.
           \_ I do not recommend Dell. They don't use standard components,
              if they go bad, you are stuck with Dell supplies.
              \_ Dell desktops usually come with 3-year warranty and often
                 4-year warranty is an option. Besides, I have never seen
                 a Dell motherboard or power supply fail. What other
                 non-standard components are there? I have a Dell Dimension
                 and I had no problems replacing video card, ram, disks, and
                 optical drives. (BTW, those were really upgrades, not because
                 the original parts failed). Yes, if you need a PC that allows
                 you to swap a motherboard a few years later, Dell might be
                 bad for that.
                 \_ My original PS from about 1.5 year ago has gone
                    bad (making loud noises). Dell sent me a new PS,
                    but it's still loud. Their case is also non
                    standard, ie, you cannot put the thing into a
                    ultra quiet case (the motherboard connector to the
                    case is non-standard) So you see, if I want quiet
                    and peace of mind when I am working next to the
                    computer, I have to replace the friggin
                    motherboard as well, because the motherboard is
                    not standard. I can't put in a ultra quiet PS that
                    I can get at Fry's either, because Dell
                    SPECIFICALLY changed the PS layout so standard
                    ones won't fit.  Their fan system is also non
                    standard, the back fan that sucks air out of the
                    CPU through the tunnel out the PC is also non
                    standard. So now I am stuck with this loud piece of
                    ($*%($% unless I replace the freggin motherboard,
                    it's a good thing they uses standard CPU. ;)
                    \_ If you care about noise, get an Optiplex. They're
                       pretty quiet.
        \_ You don't need 'fast' for general applications unless that includes
           stuff like crazy Photoshop work or video editing, or maybe a PVR.
           If you're going to run WinXP on it I'd spring for 512MB of RAM...
        \_ Goto Fry's and buy whatever's on sale.  It will be fast enough.
           \_ Has anyone ever actually bought one of Fry's $200 shitboxes?  I'd
              expect it to explode 2 weeks later.
              \_ Actually, I used on sale parts from Fry's to to cobble
                 together a machine.  The motherboard was a piece of crap
                 with a BIOS problem, but once I flashed the BIOS it was a
                 good deal.  So, if you don't mind fighting a little with
                 the machine at first, you can come out really well. -jrleek
        \_ I think you want the C.  The E runs hot, I think.
           I also think you want a 2.8 GHz CPU.  3.0 jumps up in heat a lot.
           Check for user opinions on E vs. C.
           Then again, you could just get an Athlon 64 3200+ (Newcastle) or
           3500+, which both run cooler and generally faster.

           It's a bit pricey, but looks awesome for quality & noise.  If
           you just want a good case, have a look at Thermaltake (there are a
           ton of others, but these have good, well-placed cooling with nice
           reasonably quiet fans in the case.)  If you just want fans, look
           for Papst fans--they are very reputable for quiet PC fans.  You
           may also want to consider underclocking a tiny bit and going
           fanless or getting a variable speed fan.  Cheap cases are never
           worth it if you want peace & quiet.  -John
        \_ The noise of my PC dropped significantly when I switched to a
           Zalman CPU Fan (120mm) and heat sink. The one that I bought
           was $25-$30 at Fry's. There are quieter ones, but they were
           in the $50+ range.
           I also added Thermaltake fans (90mm, 17db) which were the
           quietest fans at Fry's in the ~ $10-$15 range. Thermaltake
           is quieter than similarly priced Zalman and Vantec fans, but
           one of my 3 fans developed an annoying hum which was probably
           from a bad bearing. --ranga

           everyday for years and won't miss the $5 later.

9/22    This whole tech talk about AMD/Intel is in violation of the motd
        post spirit. Let's go back to the good ol days and talk about
2004/9/22 [Computer/HW/CPU] UID:33686 Activity:high
9/20    Underclocking my CPU has been the best decision I've ever made since
        I bought my AMD last year. It was so hot, even when idling, that I
        had to turn on my AC to keep the room from heating up to 85 degrees.
        I have an AMD 2500+ (1800 Mhz, 1.7v) and after underclocking,
        it is now 1.1Ghz, 1.1v core and is as cool as my friend's P4
        3GHz. I just reboot and regular clock again when I play games.
        BTW I'm never buying another AMD.
        \_ Is it just me or does this sound highly implausible unless you
           have a multi-cpu with really big fans blowing out of the case?
           I mean, come on, it's pretty much thermodynamically implausible
           that one CPU is going to heat up a whole frickin room to 85
           degrees. Did you flunk physics or something? If what you say
           is true I can cool my room by opening up the door to my
           \_ I had two AMD machines that were so hot they were overheating
              the room and then shutting down.  After underclocking them
              the problem went away, but the room is still noticably warmer.
              \_ So in other words your AMD machines were overheating because
                 the room was too hot, which probably means that the room
                 isn't good for running computers in, and basically has
                 nothing really to do with the design of AMD cpus. Folks,
                 you can't assume that you can run computers in a really hot
                 room, i.e. the second floor of a not very well ventilated
                 apartment during a heatwave. I've had stuff like drive
                 failures on laptops occur because of this. If your cpus
                 are failing at their rated speeds because the room is too
                 hot, that should tell you something about your computer's
        \_ You can get a 286 that will beat the pants off of your 1.1Mhz
           CPU, and it doesn't even have a fan!
        \_ What kind of shitty heatsink do you have? My 1.5ghz rarely goes over
           50C in the dead of summer; mostly 35-40C othertimes
        \_ Cooler than a P4 3 GHz?  This *isn't* really saying much.
           Also, I have an Athlon 64 3200+ (Newcastle), and it runs at 37
           degrees idle with the stock fan.
        \_ I have an AthlonXP1700 with a ThermalTake fan ($15, decent but not
           any overclocker-whizbang) and my CPUs usually 45, or 55 on a hot
           day.  If you're running at 85 that suggests either your CPU fan is
           badly clogged or failing, or you have terrible airflow in your case.
           Do you have any case fans?
           \_ I have a LOT of fans. My room is tiny, barely walkable. I have
              a 30w LCD so I blame everything on the AMD                -op
              \_ Case fans help keep the case temperature down, but help make
                 the room hotter.  You, your power supply and every other
                 component are more to blame than the CPU.  Open some windows
                 or get a 20" box fan to put in the doorway.
           \_ btw 85 is ambience temperature. My CPU used to run at 145F but
              now runs at 102F. My 1.1G is "as cool" as a P4, pathetic. Never
              buying another AMD                                -op
              \_ What kind of moron uses F for anything other than weather
                 and cooking these days? Get with the program and start posting
                 C, especially if you are a Berkeley alumni.
                 \_ Wuss.  It's degrees C or C.  If you're a real man you use
                    K.  Remember that room temperature is about 293K.
                 \_ Morons like doctors and nurses use degree F for body
                    temperature these days.
                    \_  Please explain why that makes them morons.
              \_ Gah!  We're all talking centigrade and you meant Fahrenheit!
                 85F as a case temperature is not bad.  145F as a CPU temp is
                 a little hot, but not extreme.  102F as a CPU temperature is
                 very good.
                 If your room is getting up to 85F that sounds like a building
                 problem not a CPU problem.  You put out about 100W of heat,
                 your computer puts out 100-200W of heat and your monitor puts
                 out up to 150W of heat if it's a CRT.  Out of this 250-450W of
                 heat, blaming the 60W contribution of your CPU for making the
                 room hot is stupid.
                 \_ Why are the american pig-dogs still on the imperial
                    system?  Shouldn't they join the rest of the civilized
                    world and use SI and, you know, decimal fractions.
                    \_ Celsius is not the SI unit of temperature.
                       \_ Tedious twit.
                    \_ And Kyoto.  We need Kyoto to run our computers cooler
                       to prevent global warming.  This is another Bush
                       disaster that will destroy American credibility around
                       the world for generations to come!
              \_ My P3 runs hotter than your AMD.  Stop being such a crybaby.
                 I can only dream of the day my P3 runs that cool.  When I
                 turn it off it takes 10 minutes to get to your temps.
                 \_ This whole thing sounds like "Wah!  My AMD CPU is warm but
                    my friend says his P4 is super cool.  AMD = TEH SUCK!"

9/17    How difficult is it to host a virtualized FreeBSD server?  Not
        commercially, just want to let a friend go nuts with it.  Something
        like what's described at
        but I don't care so much about uptime and reliability.  Is this guy
        just using a jail, or is it more vmWare-like solution?
        \_ Jail.  Very straight-forward.  I love the part about their special
           technology.  You just need a unique IP/server.  -John

9/12    I don't play games but I want to play Beyond Good and Evil. I seek
        people's opinions as to the cheapest way to do this. I own no console
        and my computer has only the standar-issue graphics card.
        \_ What's your CPU and RAM?  Do you have an AGP slot?
           \_ 1998 HP Pavillion. 199 MHz. 128M RAM. Yes - The old
              fashioned kind.
              \_ No such thing.  The Pentium II started at 233 MHz.  Oh, and
                 there's a difference between Hertz and MegaHertz.
              \_ You'll either need to buy a console or get an all-new system.
                 6 years is long enough for an upgrade anyway.
                 \_ OK. But would it be better to buy a used PS2 or Xbox,
                     instead? That's what I'm asking, really. -OP
                    \_ If you're ONLY concern is to play the game as cheaply as
                       possible, then buy (or rent from Blockbuster) a used
                       console.  The graphical quality will be best on a PC
                       with a DirectX-9.0 video card, but that will be a lot
                       more money.  If my system was 6 years old I'd upgrade
                       for a lot of reasons, but your priorities may vary.

                       \_ Thx. It actually hadn't occurred to me that I can
                          rent consoles. That's what I'm going to soon
                          as the wife goes out for awhile.
                     \_ New ones are ~$150, aren't they?  You can also rent
                        them from some video stores.
                     \_ Why don't you just look and see? They're the same
                        price new. I'd pick based on if you think there are
                        any other games of interest. But, Xbox is capable of
                        better graphics, which might be better in BG&E.
                        \_ As above, thank you both. These were useful answers.
2004/9/4-6 [Computer/HW/CPU, Computer/SW/Security] UID:33348 Activity:moderate
9/3     Thinking about getting an opteron? If security is your concern,
        maybe you should think again:
        \_ Erm, maybe I'm missing something, but that page argues that
           if someone can gain root access and flash the system with
           malicious microcode, they can in the future gain full access
           through mere userspace privilege.  True, but wouldn't that apply
           to any box where you can flash the bios as root?  -John
           \_ on the PC, linux for example bypasses the BIOS except for
              initial bootstrapping.  modifying processor microdoce gives
              a more persistent hook, as would modifying firmware of
              any DMA-master capable device that is not reprogrammed
              by the OS.  this isn't the end of the world, but surely
              adds to the "security is hard" mountain.
        \_ Very few places need to be this concerned about security.  The
           financial industry, for example.  The finance and high security
           government facilities I'm aware of would be no more or less
           freaked out by this than the idea that someone got root in the
           first place.  If they take a gun to your sysadmin's head at a
           party they'll get access, too.  So, if you're thinking about
           hiring sysadmins who might show at a party maybe you should
           think again.
                 \- hello, it is interesting to talk to people in the
                    financial world about some of the "attacks" they
                    face, for example organized crime infiltrating the
                    mail room. also you have problems like say how to
                    not let the backup staff read the data. ok tnx.
                    \_ Yes, that is what I was getting at with the sysadmin
                       at a party line.  There are lots of easier ways to
                       do nasty things that don't involve updating micro-code
                       or anything high tech at all.
           \_ Wow, someone who actually knows something. Thank you for
              showing up.
              \_ That's why I avoid parties.  It has helped me land better
                 jobs.  :-)

8/29    So, what processor would you recommend for a desktop PC?  What's
        got the best Bang-for-your- buck right now?
        \_ I'd say an AMD Athlon XP. Exact model/speed depends on how much
           buck you have, and how much bang you need. If you live in the
           bay area, go to Central Computer in Hayward.
           \_ What about the AMD 64 processors?  Is there any value in
              running in long mode yet?  Linux 64 maybe?
        \_ Depends on what you're doing with it.  Games/no-games?  Just
           surfing and email?  For mozilla and no games you can get a nice
           machine from Dell for under $500.

8/27    I'm currently running a 1.2 Ghz Celeron with 386 megs or so of RAM.
        I'm thinking of buying a new machine, but I want to go cheap, maybe
        less than $500.  I want to end up with a nice machine and a crap
        machine at the end of this.  (Crap machine so my wife can do email and
        stuff) so don't need a CD drive or monitor, and the video card
        doesn't have to be great because I already have a nice one in my
        current machine. A TNT2 would be fine (It just has to be good enough
        to play video full screen). Any suggestions?
        Will I be able to use the old ram in my new machine?
        \_ What are you proposing?  Buying a crap machine for your wife?
           Buying a tricked-out new machine and giving her the Celeron, or
           buying a new machine, and putting some of the Celeron's parts in it?
           \_ Option B + C.  I going to take the nice video card out of the
              celeron, so I'll need one to replace that. I'll also take the CD
              burner, and some RAM if I can.  I'll probably need to buy: New
              processor, motherboard, case, harddrve, and RAM for the new
              \_ OK.  Almost any video card can play full-screen videos.  I
                 could sell you an old Radeon VE for $10 or something or you
                 can go on Craigslist.  The RAM is not transferable to the
                 new computer because the Celeron is probably using PC133 and
                 a new machine would be using DDR400 or the like.
                 I bought an ATX case I like and have had it for 6 years.
                 If you're video-card shopping, the magic word is 'overlay'.
                 \_ What's an overlay?
        \_ Dell is routinely selling 2.8GHz systems for less than $500.  See
   The Dimension 4600 systems are great and include
           integrated video (but have an AGP slot), SATA, and typically 512MB
           Ram.  Watch out for the 2400's though, they don't have an AGP slot.
           \_ That's interesting info.  However, aren't chips up to 3.8 Ghz or
              something now?  Shouldn't I at least be able to get a AMD 64-bit
              3Ghz processor cheap by now?
              \_ Search the same page for amd and you'll get some results.
        \_ And what the freak is an AMD Sempron?  Sounds like a word for a
           deformed shrimp.
           \_ It is a brand-name that AMD came up with to prevent
              Athlon(TM) brand from becoming perceived as "low-end"
              because, frankly, they're not.  Most of the current desktop
              Sempron processors are K7-based cores.  The only exception
              is the 3100+, which is basically a true Claw Hammer (256k
              L2) with a fuse blown to disable long-mode.  It's
              practically identical to a Drill Hammer Athlon 64 2800+
              (512k L2), other than the fact that it has a smaller die and
              that it cannot enter long-mode.  All mobile Sempron chips
              are K8-based, again with long-mode disabled.
              It appears that all corporation-generated trade-markable
              names get made fun of.  Can _you_ come up with something
              better?  Seriously, I'd like to hear your opinions.
              And above comments such as "I'm currently running a 1.2 Ghz
              Celeron" and "aren't chips up to 3.8 Ghz or something now?"
              really saddens me.
              \_ why does that sadden you? i was running a 500 MHz celeron,
                 up until a few weeks ago, and it was all right for most
                 things, except playing some movies and all games.
                 though having 1 GB ram does do a lot.
              \_ Those "2800+" numbers have become silly with so many chips
                 with the same number but different performance. Oh and do you
                 work in marketing? There is no need for (TM) on the Motd(TM)
                 CSUA(TM) Motd(TM) Copyright (C) 2004. All Rights Reserved.
                 \_ As much as I hate all those numbers, those are all that
                    most people look at.  In fact, it saddens me that people
                    buy things based on numbers instead of even attempting to
                    learn a bit more about the products they're buying and
                    thinking about their requirements.  It's not all that hard
                    to differentiate them if you just try little bit.  For
                    example, at this point, I just cannot possibly recommend
                    anyone buy a K7-based processor.  Embedded memory
                    controllers on K8-based processors are simply too
                    worthwhile to pass on.  No, I don't work in marketing.  I
                    work in microprocessor design verification. --ricky
              \_ I'm kinda wondering about your sadness too.  What part of
                 that post makes you cry?
                 \_ Except for that certain Celeron (known as CeleronA, I
                    think), they're like 300 horse power engine attached to a
                    1980's 2-speed automatic transmission.  Seeing as how
                    during the most of the period these were available, Athlon
                    was also available at similar price points, it makes me
                    feel sad that people were buying these.  The other part
                    about 3.8GHz thing, to me anyway, shows the lack of
                    understanding of microprocessors in general by the general
                    population.  Not much I can do about it, but still
                    saddening. --ricky
           \_ I'm sure the marketroids who probably spend many meetings
              coming up with that would be hurt. I can only guess it's related
              to the latin, as in "semper fidelis". I don't think it works
              they way they think though. Just like celeron is supposed to have
              the association with excel, accelerate etc. but to me just sounds
              like celery. Or "sell her on". Or cellophane.
           \_ Semprini!
        \_ Update, I was going by Fry's anyway, so I stopped by to take a
           look, there were some good deals, so I went ahead and bought
           what I needed.  I got: Athlon XP 2800+ and mother board for
           $100, 512Mb of 400 Mhz ram, $60, and a Maxtor 7200 RPM 160 GB
           HD for $70.  In particular I think that HD is a pretty dang
           good deal.  I think this should cover me.  -op

        Pentium 4 560 (3.6GHz)     155W idle   258W max
        \_ Old news. Prescott is a dog. Intel knows this and has terminated
           all 90nm Pentium 4 products in favor of Pentium M.
           \_ These are for the latest Athlon 64 and Prescott CPUs, and I am
              not aware of the above data being readily available.  Also, since
              the first Pentium M-based desktop CPU isn't scheduled to arrive
              until 2006, it's all Prescott right now for Intel until then. -op
              \_ It is indeed.  Tejas and Jayhawk, the followons to Prescott,
                 were cancelled:
        \_ 258W is nuts.  Intel can't seriously expect people to build real
           servers in compact data centers with a nuclear reactor like that.
           Even without the graphics card, 155W idle (plus a bunch of drives
           in a server) is insane.  Anyone here work for Intel and have any
           inside dirt on this problem?
           \_ I don't work for Intel, but I worked for another microprocessor
              company that shall not be named.  It's no secret what's going on,
              it's the hottest topic in the industry right now.  Just google
              90nm and leakage power.
              \_ well what I really was asking is what Intel was thinking
                 when they shipped this beast and if they really thought that
                 Intel Inside(tm) was enough to overcome this horrible heat
                 \_ Previous to 90nm, most die shrinks came with a reduction
                    in power consumption.  You could just say, "It was too
                    late once they realized they couldn't fix the problem
                    (fast enough?)."  Anyway, their yield is increased with
                    90nm; more chips per wafer; more money.
                    AMD will also be releasing 90nm parts for desktop and
                    mobile; I am curious how they will do. -op

           \_ I don't work for Intel, but Nocona (codename for next Xeon
              iteration) will have SpeedStep.  Probably they will have
              SpeedStep for Pentium 4.  True, max power doesn't change, but
              idle will lower and you will stay there longer. -op

                 M based desktops.  See the link about about Tejas and Jayhawk.

8/7     I have a FreeBSD box serving Samba, NFS, DHCP and DNS (as a
        forwarder behind a firewall and for a few "internal" boxes.)  It's
        creaky and old, and about to go, and it gets too hot.  Can someone
        give me a tip as to whether there are smaller devices that can do
        all this (like some sort of low-cost NAS with all the above
        functionality) so I don't have to have a PC running in a poorly-
        ventilated room anymore?  -John
        \_ Some options that come to mind:
           1) If you don't mind running debian, get an old cobalt raq3/4,
              wipe the drive and install debain. These boxes can be had
              for $100-$200 on ebay. They can take two 120 gb hd's and
              can be passively cooled (K6-2's don't put out much heat).
              My intern has his sitting under his bed and has been using
              it as a file server for more than a year. If you really
              want to stick to BSD, older cobalt boxes can be coaxed
              into running NetBSD.
           2) Replace the motherboard with a via c3 based mb. You can
              usually replace the tiny cpu fan with a chipset heat sink
              and run the board with passive cooling.
           3) Get a mini-pc with a celeron or an underclocked Athlon
              mobile. Shuttle makes some reasonable quiet ones with
              good ventilation.
        \_ I took an old 1U server box, loud as hell, built it out with the
           loudest, fastest shit I could find, dropped it in a closet and
           forgot about it.  The closet isn't hot, the server isnt hot, the
           room isn't loud.  The case it off, btw because I needed to use a
           card that wouldn't fit sideways.  No problem.

6/17    For general purpose computing do you think a dual p3-700 with 100mhz
        bus is faster than a single p3-700 with 133 mhz bus?  When would the
        single cpu be faster?
        \_ For most applications, the bus speed will not matter. So you
           are looking at 1 CPU versus 2 CPUs. You may not receive any
           benefit to 2 CPUs, but they will not hurt. So the dual is
           almost always going to be faster. The exception is if you are
           limited by the bus speed (lots of I/O) and even then 133 is not
           much faster than 100.
        \_ Bus speed helps for applications that access memory in large
           "stride".  Having an extra CPU and not using it at all will actually
           slow the system down by 1-2% due to extra polling.
           \_ No, because the CPU will be used by the OS. Real benchmarks
              I have run show about a 10% gain on 2 CPUs even if there is just
              one non-threaded process running. The other CPU will never
              be 100% idle.
              \_ Sorry, I was refering to OSes which are not dual-cpu aware.

        them?  I took a Powerbook Pismo to we-fix-macs and was told to shell
        out $351 for reburbishing the processor boards (actually the genius
        said they would repair and refurbish the CPU!).  If so, it doesn't
        seem worthwhile to reapir at all!
        \_ Mac people... hehehe.  If it was a PC, you'd spend less than that
           to get a new motherboard and cpu and end up with a better computer
           than you had before for less money instead of the same computer with
           equally old parts.  Did they also change your fan belt oil and the
           power supply equalizer?  What about your cam shaft bearings and the
           differential rotar terahertz storage display?  *snicker*
           \_ I remember trying to fix parts on my old PC.  You'd replace
              one thing and Windows wouldn't boot normally, so you'd go to
              'safe mode' and see that not only does windows insist on trying
              to find stuff on your old motherboard, it has your mouse device
              loaded like 8 times, still is looking for a sound card you
              replaced last year, and the only sure way to clean this up is
              to reinstall from scratch.  And reinstall DirectX.  And the
              endless rebooting..
              \_ It's generally better now.  You can tell it "that part
                 doesn't live here anymore"
              \_ I'm still using my old PC except since I first built it I've
                 changed every part except the floppy, a few cables, and what
                 little remains of the case and PS.  Nothing you're talking
                 about has ever happened and I didn't spend $351 to get my
                 cam shaft rotorhertz drive pixelation problem refurbished at
                 some rip off joint that survives by screwing endless
                 generations of mac wielding english major freshmen.
                 \_ My main expectation with a repair is that I should get
                    new parts replacing the broken ones, instead of some
                    parts just as old or even older salvaged from other
                    dead units bought over ebay.  -- op
        \_ well, every warranty I've seen says that the manufacturer could
           use refurbished parts
           \_ but can the "refurbished" part be from another computer that
              has been equally old but just hasn't failed yet?
              \_ yes
                 \_ Are you talking about out-of-warranty repair?
                    \_ in-warranty ... out-of-warranty, they can still
                       be refurbished, but the implication is that the
                       refurbished parts need to be "recertified".  Guess who
                       determines the part is recertified (hint: not the
                       manufacturing company).
                       \_ I always thought that repair means replacing bad
                          parts with new parts, and refurbish means checking
                          and repairing new or almost new (returned by
                          unhappy customers with 30 days) units.  Guess I was
                          \_ I've found that typically, a warranty means if
                             it breaks, you get one that works.  Not
                             necessarily a new one.  As far as I can tell,
                             the only difference between in-warranty and out-
                             of warranty is in the latter, you pay for more
                             than just shipping it to them.

           open them side-by-side and compare.

                   power and imposes our freedom to run useful tasks such
                   setiathome and gene folding and porn storage.
           \_ motherboards, etc, are cheap.
              \_ so are lots of >700 Mhz processors...
        \_ Here is a very fundamental question. Is CSUA more CPU bound
           or disk space bound? I would say definitely the latter because
           of all the h0zers storing email and never cleaning them up.
           Secondly, it's easy to do "ps aux" and see who should get
           squished, but it's not so easy to do "df -k /users/*" because
           of file permissions, so we don't have a clear idea on who to
           target. My point is we need an alumni who works at Western
           Digital to donate free space more so than an alumni who works
           at AMD/Intel to donate a powerful space heater that will most
           likely be underutilized.
           \_ Why not both? Haven't you seen soda's load a 8?
              \_ Before spamassassin, soda didn't have any shortage of cpu.
                 Faster/multi-spindle disk would help with that, but that's
                 about the only thing that cpu would help.

3/8     What is an acceptable temperature in a computer case? I'm asking
        because as summer is approaching, my case is already 90 something
        farenheit, and I know that it'll probably jump to 100 something
        during the summer. My CPU is currently 134F and system (mother
        board) is 96F. I'd hate to fry my CPU and HD. Should I be
        concerned and get those fancy heat exchange things from Frys?
        \_ Dear posters, I bought a heat paste from Frys (it was a whopping
           $8.00) and got the CPU to go down to about 122F. Thanks. Now I
           worry about my HD because that's where the data is, but that's
           gonna be another post.
           \_ Consider placing the HDD in the lowest available bay and moving
              optical drive(s) as far away as possible.
           \_ do you have case fans in the front? you should have a 1:1 ratio
              of fans sucking air in and fans blowing out. i have my HDD
              directly in the airflow path. it never reaches above 42C.
              \_ Why do you need front case fans?  As if the rear fans won't
                 draw air through from the front?  They'll create a complete
                 vacuum inside your case?
        \_ I had a MB/HD death when the case was 150 and the cpu was 190 --oj
        \_ You're getting into the danger zone.  CPUs in the 60-65C range will
           run normally but ocasionally have 'soft' errors.  You will have
           shortened CPU life also.  Try to keep your CPU under 50C (122F).
           A MB temp of 96F doesn't sound too bad, but the ambient case temp
           affects your HDD temp.  Try running with your case open and see how
           it helps...
        \_ Why go fancy?  Just go low-tech and buy a $10 fan from Walgreens,
           then open the PC case and blow on it.  It's going to carry away more
           heat than most fancy PC fans.
        \_ I agree, < 50 deg C is good for CPU temperature.  You should
           buy some thermal paste and re-seat your fan with it.  Remember,
           just enough paste to make a very very thin layer is all you need.
           What CPU are you using BTW, and does it already use paste
           or some kind of heat-transfer pad?
        \_ I run an open case.  The heat sensors say my cpu is ~105F and the
           case is barely above room temp.  When I ran it closed I was at
           ~130F cpu and about ~108F on the mb and didn't get any errors.  I
           have it open for easy access because I change hardware a lot, not
           because I was worried about heat.
        \_ 100 is probably a good upper bound.  If you can track your CPU temp
           125 is a good upper bound, and 140=fried.
           If it's really hot, I'll take the side of my case off.

1/24    I'd like to upgrade my 15 year old cordless phone which is still using
        40 something megahertz. Should I get a 2.4GHz digital phone or
        a 2.4GHz DSS (digital code hoping) phone? Which one is more secure,
        has a better quality, range, etc? By the way I also have a cell phone
        but the quality (clarity, lag, etc) is still inferior to a land based
        phone. Thanks!
        \_ How about a 5Ghz phone, since 2.4Ghz phones have been known to
           interfere with 802.11b wireless routers (in case you have one)?
        \_ No one is listening to your boring phone calls.  Security should
           be the last reason you choose one phone over another.
        \_ Just a note: frequency has little to do with quality here, or
           even range.  Go for 900 Mhz, avoid the radiation and
        \_ Another note:  The Panasonic handsets heat up with 2.4 GHz (and
           probably 5 GHz).  The 900 MHz one does not, and has great battery
           life.  You probably get better range with 2.4 or 5.  As far as
           quality, 900 is fine -- if you notice clicking about 10-20% of
           the time, just rock the switch to the left a few times to change
           to another channel.  I've never heard any interfering conversations.

1/1     I got a IBM R40e recently with windows Xp.  I'm wondering what I should
        run (if anything) to stress the computer out.  I heard that if a
        laptop is going to break it's going to break in the first few months of
        use.  Should I worry about this?  I'd much rather ship this back in
        30 days to the seller rather than deal with IBM warranty.  Thanks.
        \_ setiathome
           \_ bah. recent games are still generally the things that work a
              computer the most.
              \_ In terms of actual stress testing, not really.
              \_ yeah goof point. seti only stresses the CPU.
        \_ Video editing and reencoding.
        \_ I had a Dell Inspiron that had an overheating GeForce GPU --
           only found out after playing Flashpoint on it for a day.
           It also took two or three exchanges with Dell before they figured
           it out.
        \_ M$ Fight Simulator in demo mode with highest randering options.
           That's how I stressed a PC I bought a few years ago.  Turned out
           that it hung after 15min or so and it was a CPU problem.
        \_ Prime 95 has a good stress mode, not for the video card though. It
           was able to detect faulty CPU operation when overclocked, even though
           stuff would appear to run ok.  You have to run the
           specific stress test. Some people run two instances.
        \_ is it just me or it seems like modern computers are less fault
           tolerant than ever?
           \_ It's just you. Personal computers are much more fault tolerant
              now than they used to be. Apparently you've never run an AppleII
              or a C64. People's expectations change and they forget about the
              recent past. It would have been ludicrous during the dawn of the
              PC era to think that a C64 could have uptimes of months. You were
              lucky if it didn't bugger out after a couple hours. You can't
              compare today's multipurpose PC to mainframes of the past because
              that's like comparing apples with oranges. The fact is that PCs
              have essentially replaced mainframes because they have become
              increasingly more fault tolerant to the point that they can be
              reasonably used in an enterprise market. That doesn't mean that
              they are as fault tolerant as a mainframe, but the fact is that
              you can keep a Linux/BSD x86 box running for months shows the
              vast improvement over time of the OS and the hardware archtiecture
              of PCs.
              \_ By "fault tolerant" was the poster asking about how often
                 something goes wrong, or how likely the machine keeps going
                 after something has gone wrong?
           \_ Not all modern computers are designed to be fault tolerant. If you
              have a plain Pentium IV and non-ECC RAM, you aren't getting the
              greatest reliability but probably enough for most people. With a
              Xeon and ECC RAM, you get better data integrity in both the CPU
              and from the RAM. Enterprise storage equipment has more. I guess
              data integrity isn't the same thing as the real fault tolerant
              stuff on servers like RAID and other redundancy, which is what
              you would need to tolerate disks, psus, cpus etc. going bad.

        drives get corrupt data with "IO" errors.  I fear this is related.
        badblocks -w showed no errors. drives work fine after reformatting
        ext3. The overclocking was done with very fast case fans and a
        copper CPU cooler rated for overclocking.  The CPU fan was turned
        up all the way.  Do you think overclocking damage would cause this
        error?  Could overclocking fry an IDE controller?
        \_ If you overclock the front side bus, you are stressing everything
           on that bus, including IDE interfaces.
        \_ It's quite likely you fucked your system, yes.  Did you have
           temp measurements before and during for this 'test' or did you

12/29   I am hearing less and less about AMD computers.  Almost every local
        store is selling intel inside machines.  Is AMD fading away?  What
        was the third chip maker?  There was Intel, AMD, and one other
        competitor, but I have already forgotten its name.
        \_ Stock went from around 5 to around 15 in the past six. Don't know
           what that means, except wall street seems to think there is value
           in AMD. As for 64 vs. 32, people didn't know what to do when 32
           vs. 16 came out, then came Windows 3.0. I guess you can write
           bigger bloatware, since now you can address a lot more space...
        \_ umm, do you hear much about computers at all?
        \_ Cyrix, see wikipedia for a history.  AMD has a relatively
           inexpensive 64-bit CPU, but there is no demonstrated consumer
           benefit for it.
           \_ there are a few "third" chip makers. i don't know if cyrix is
              even still around, these days it's probably VIA. transmeta too,
              but they're more of a laptop thing.
              \_ Cyrix was bought out by National during the good days, then
                 National basically went South (and is continuing the long,
                 painful slide to oblivion to this day). They sold the assets
                 for Cyrix to VIA, which has basically done nothing with it.
                 National didn't do much with Cyrix either, except sell a couple
                 for embedded products. Problem with Cyrix is that chips always
                 get cheaper, and it doesn't make sense to build low performance
                 low margin chips that are going to be obsolete in two months.
                 What you want to do is build high-end high margin chips and
                 live off of the skim until it becomes commoditized.
           \_ thanks, much more informative response than the first non-sense.
              \_ nonsense begets nonsense.

              need more than 640k either.
              \_ faster is up for grabs; cooler is marginal (89 watts vs.
                 100+ watts?); costs less is true.  I should have written that
                 there's no consumer benefit to the 64 bits.

                      is that you want to find bounds on a certain
                      number called Chaitin's omega.  If you know something
                      about that number you can solve lots of problems.

                      solve any problem which can be precisely stated.
                      You get lower bounds by simulating programs until they
                      stop, and you get upper bounds by searching for programs

           Here's a start:
           \_ can any of those run with no fan?

              Let me know if you find something. -brett
        \_ There's nothing wrong with a huge fan.  Huge fans are good.  That
           means they spin slower to move the same air as a smaller fan.  That
           means they're quieter.
        \_ The main thing that's obscene about current processors (AMD and Intel
           both) is how much wattage they consume - the 3ghz P4 can eat upwards
           of 80 watts, and I've heard reports that Prescott may be in the 125
           watt range.  And people leave these things on 24/7, and then wonder
           why there's a power crisis.
           \_ there's a power crisis because of several reasons. 1) monopoly
              abuse in the power market, 2) lack of effort being put into
              developing alternative energy sources, 3) waste, 4) mismanagement

              \_ I run seti on my desktop machines at work, but I power off
                 those machines when I leave work.  My priorities are 1)
                 conserve power, then 2) put to good use the power that I can't
                 conserve (ie. all idle CPU cycles).  For this reason, I don't
                 run seti on my laptop at work, since my laptop is smart enough
                 to turn off the CPU clock when it hits the idle loop.  Running
                 seti on this laptop will increase power consumption, defeating
                 the original intent of seti.

                         this is a case where you dont want completely

                         achive is linear in air flow and exponential in
                         a factor based on turbulence. this is why some
                         fans have non-smooth blades to increase turbulence.

                         disk drived you want laminar flow to avoid platter
                         vibration and for cooling you wanted more turb flow
                         for greater heat capacity. it's a pretty cool [NPI]

        It's a 2 page IQ test.  When it asks for email address at the end,
        just give any fake address.  You'll still get the results after you

                         is that it isnt timed. e.g. someone who can do the

        necessarily has to be in the same league as P4M.
        \_ go with the Pentium M.  It's designed from the ground up as opposed
           to the 3M and 4M which are closer to desktop CPUs at heart.  I hear
           the Pentium M trounces them anyway.

                \_ Don't look at the X for CPU, look at it for size.  It's
                   comparatively tiny, tremendously robust, and weighs almost
                   nothing.  The T-series has a bigger screen and DVD.  If you
                   are worried about price, get a refurbished one--that's what
                   I have (X-20) and it's brilliant.  -John
                \_ Dewd, the T40 can come with either the Mobile Pentium 4
                   (aka Pentium 4-M) or Pentium M (aka the Centrino CPU).
                   All reviews of the T40 I've seen are with the Pentium M.
                   1.6 GHz Pentium M ~= 2.4 GHz Pentium 4-M.
                   And as the previous poster wrote, the Pentium M was
                   designed from the ground up as a mobile CPU.  The Pentium
                   4-M was based on the Pentium 4 desktop CPU; Intel had
                   not planned for a notebook version until they got
                   caught up in the raw MHz game (consumer:  "This Pentium
                   3 is only 1 GHz, and the Pentium 4 is 2.0 GHz!").
                   Also, the X has a 12" screen; the T40 has a 14" screen but
                   weighs more, as the previous poster wrote.
                   There's also notebooks with an AMD CPU if you want
                   something a step above a Pentium 3-M.  The Fujitsu
                   S2000 and S6000 series are almost identical, except
                   for the CPU; the S2000 has an AMD CPU, and the S6000 has
                   the Pentium M.  They're both new, so you can check
                   performance numbers on  My impression is that
                   the Pentium M blows the AMD CPU out of the water in
                   performance and energy consumption.

        should I looking for?
        \_ Fujitsu S6120D.  Pentium M is what you want, multiply GHz by 1.5 to
           get equivalent Pentium 4 speed
           \_ By 1.5??  Let's see a URL for that.  There's nothing wrong with
              a 1.0+ ghz P3 for normal use.  If you're playing quake on it,
              the graphics subsystem will be so slow it won't matter what cpu
              is in there.
              \_ Are you kidding?  My Radeon 7500 mobile card does very well for
                 all the games I've played, including several of the recent 1st-
                 and 3rd-person games.

                    that.  No, I'm not kidding.
                    \_ Yes, I do turn on all the graphics, and display at hi-res
                       (1400x1050), and play the games that way.  And?
                       \_ I asked what games you're playing.  Solitaire in 3d
                          at any resolution isn't taxing.
                          \_ No, you didn't ask.  But now that you have:
                             GTA 3, UT2k3, Enter the Matrix, Splinter Cell,
                             Warcraft 3, and a few others.
           \_ google for "centrino 1.5 multiply pentium".  The Dell Latitude
              D600 weighs 5.5 lbs., but it has a Mobility Radeon 9000.  The
              Fujitsu has the integrated graphics, so 3D games are a no-no.
              \_ 5.5 lbs?  Why don't they just strap a cpu to a brick?
                 \_ That's true.  I'll be pretty happy when I can get a 4.5
                    lb. notebook with 3D acceleration, a 15" screen, and
                    is Windows-native.  (Yes, I know about the Macs.)
              \_ url re 1.5x:
                 \_ Nuh uh!  This is comparing Pentium-M versus the *MOBILE*
                    version of the P4 not the desktop version.  And it's more
                    like 1.25 to 1.35 except for the highest end chips where
                    yes it is about 1.5x given Intel's own charts where you
                    don't have a clue how they came to these conclusions.
                       \_ which confirms what I said.  1.5x is only true for
                          the highest end chips and those benchmarks aren't
                          graphics oriented if that matters to the OP.
                          \_ Systems with the 1.6 GHz Pentium M's are
                             $50 more expensive than 1.4 GHz these days.
                             Graphics oriented ...
        \_ The ThinkPad X series now has the Pentium M as well, but the
           screen is 12".  The T series weighs 5 lbs. and is $$$.

                             \_ Hmm, I did but it's not there now.  Anyway, I
                                find it hard to believe you're playing some of
                                those games at with everything on at hires and

12/18   If "single" is for 1 and "dual" is for 2, what are the corresponding
        words for 3 and 4?  Thanks.
        \_ In (linguistic) morphology, "trial" is used to describe a noun
           form in a couple of exotic languages (most famously, Fijian) that
           corresponds to 3 of that number (the single/plural distinction in
           English splits into single/dual/trial/plural in those). The OED
           has this as the sole usage of the term as an adjective. There is no
           corresponding term for 4 in this context since no known
           language splits off 4 as a separate number class. -alexf
        \_ triple, quadruple
           \_ But I thought "triple" and "quadruple" are in the same category
              as "double", not "dual".  No?
              \_ single, double, triple, quadruple
                 mono, bi, tri, quad
                 I believe dual is a unique case
                 \_ dual is a synonym.  (dict is your friend)
                    though the distinction of double (duplare) and dual
                    (dualis) is interesting to note.
                    \_ "dict dual" says:
                        "3: a grammatical number category referring to
                            two items or units (as opposed to one item
                            (singular) or more than one item (plural));"
                        So I guess it should be singular, dual, plural.  That
                        means since we call 1- and 4-processor machines single-
                        and quad-processor, we should call 2-processor machines
                        double-processor instead of dual-processor.

12/15   is there a rule of thumb that relates the processor speed/type
        to the number of interrupts it can handle per second without
        significantly affecting its performance? specifically, I'm
        wondering if about 1000/s (i.e. 1 kHz) is too much for a P II.
        \_ what is too much?
                \_ 1000 interrupts/ that too much?
                   \_ what is your definition of too much?  the cpu keels
                      over and dies?  latency or throughput drops to a
                      certain level?  what level?   but like the next poster
                      said, depends on your isr, your driver, etc.

              that adj.  But we don't.
              \_ You imply too much. "Googlable" has been around for awhile.
        \_ USB 1.1 has a data rate of 12 Mbps. USB 2.0 has a data rate
           between 120 and 240 Mbps. To a rough approx. 2.0 is between
           10x and 20x "faster" than 1.1. You should really have google'ed
        \_ Thought 2.0 was 480 mbps...anyway USB is CPU dependent,
           thus my experience is that when I'm pushing lotsa data
           through the bus my computer starts chugging.
        \_ Someone erased this, but it's 12 Mbs versus 480 Mbs. --dim
           \_ The speed is also dependent on the devices. The slowest
              device dictates the speed of all the devices. If you
              plug in a 1.1 device on a 2.0 chain, the entire chain
              degrades to 12Mbps.

11/26   A serious question about this:
        I have zero experience with recent apple hardware or software.
        My company needs rock solid NFS hosts at low cost.  Performance isn't
        an issue.  The clients will be Solaris 2.7 and Linux 2.4.  Do any of
        you have any experience with this?  Does it sound good/bad to you and
        why?  Any info, urls, whatever is much appreciated.  BTW, this isn't
        a religious issue.  I just want something that will work and isn't
        going to cost me an arm and a leg like EMC, Hitachi, or IBM and I
        sure as hell don't want to start building my own.  Thanks!
        \_ I'd be wary of any ATA array.  IDE just isn't designed for large
           file service projects.  Also, this sort of thing looks like super
           overkill for what you describe.  I suggest finding a good supplier
           of prebuilt *nix boxes, preferably something running a BSD tcp stack
           for the sake of NFS.  I found a fibre channel array from
           that runs $1700 per .5TB.  Had no trouble with it yet under windows
           2k, mandrake, and freebsd.  Alternatively, you may want to look at
           the Sun A1000 line.  --scotsman
        \_ I would not consider the XServe as a general-purpose server at
           this point.  Apple just doesn't have a server pedigree (except
           a pedigree of abandoning their server products).  -tom
           \_ apple's xserve is an incredible piece of hardware, but overkill
              for what you need.  build a box from  also,
              dell has $1k 1U servers with one year of on site support and
              two more years of by-mail support.
        \_ Solaris has a great NFS support and the most featureful NFS
           implementation. Why would you want to serve Solaris client with
           anything other than a Solaris server?
           \_ because Sun's low-end server hardware sucks.
              \_ In what respect? Do you really need 3GHz Athlon CPU on an
                 NFS server? Take a look at Sun Fire V120, a very decent low-end
              \_ their hardware also is unreasonably expensive, as is support
                 as well as people who know solaris.
                 \_ A configuration with 1 GB RAM, 72 GB of disk, and a
                    650-mhz processor is $6000.  You can get 3 much faster
                    Intel boxes for that much.
                    \_ What they gain in speed, they loose in software
                       robustness and support. Specially, if you need an
                       NFSserver, the question should be a no brainer. Also,
                       who pays the list price for Sun hardware? Talk to a
                       salesman. They'll slash the price by up to 50%
                       depending on how deep your pockets are.

                           cost you three times as much, at least.  And don't
                           tell me Sun equipment is more reliable;  some of
                           my clients run thousands of high-load servers, and
                           the Compaqs and Dells and other PC boxes of their
                           world don't suffer any more outages.  -John

                          \_ You get incomplete and unstable NFS support
                             and funky RAID software. See the original poster's
           In addition to the IDE
           flakiness that someone mentioned, AFAIK, you can't mirror the boot
           disk on the xserve since it does not have an internal RAID
           controller and OS X probably does not support putting / on a
           software RAID device. Would you really like to take your server down
           for hours when the boot disk fails? If you're looking for a cost
           effective SCSI array consider the new Sun D2 (JBOD) or the 3310
           series (hardware RAID).
           \_ Read the link above:  OS X supports RAID devices.
             \_ But it doesn't support putting your root file system on software

                   ok tnx. --psb
           \_ Forget software RAID anyway. Performance *is* an issue, although

9/7     I'm building my own system. I've decided to get my CPU+MB from NewEgg.
        What is a good place to get mem, HD, and my Geforce? As for the case,
        I gotta go to Frys cuz I gotta see what the case looks like in person.
        \_ Before ordering anything from anyone, go look at
           Great prices and out of state so no taxes.  I had them build 2
           custom boxes which showed on time and to spec with decent parts
           on the unspecified stuff.
                \_ seems cheaper, maybe YOU should check it out
                   \_ Taxes, son, taxes.  I know newegg and others.  Also,
                      newegg isn't building custom systems which micropro will
                      do for you.  I've done the math.  On some systems you
                      can save as much as 10 bucks if you carefully order parts
                      from all over the net and then you still have to build
                      the damned thing.  "seems cheaper" is not cheaper.  Just
                      trying to give someone some help which you're not.
        \_ say I'm getting a MB with KT333 chipset. The FSB is rated 100/133,
           so how much more will I gain from using DDR2700 over DDR2100? Is
           DDR2700 good only when the FSB is 166? This info is not on
           tomshardware by the way.
           \_ 2700/CL2.0/333 >> 2100/CL2.0/266 by 0-25% depending on how
              memory intensive your application (game) is.  If you're building
              a top end system then get the 2700/CL2.0.  If you're going to go
              light on the cpu, video, or some other speed related part, then
              save your money across the whole system and get 2100/CL2.5.

2/21    reposting my question.  Is it possible to filter gige traffic
        with freebsd on x86?  Can the fastest pentium out there do that?
        I'm talking about running ipfw or ACLs.  Please do not turn this
        question into a troll on linux vs freebsd.  Thanks.
        \_ Processor speed is definitely not your problem.  I think you may
           run into problems where gige would overwhelm the PCI bus.  Not
           sure though.  Do some back of the envelope calculations and see.
           \_ A 64 bit PCI bus at 66MHz should be good enough. All major
              vendors have servers and workstations that come with it.
        \_ Even if this was possible, you probably need a heck of a server
           to be able to do that. Sun support people for example recommend, as
           a rule of thumb, in order to saturate a GigE pipe, you need to have
           one fast modern CPU per GigE NIC. Plus, you need another CPU for
           just processing the rules. Your looking at a quad CPU server with a
           64bit/66MHz PCI bus.
           \- my longer answer is in th emotd archive, but it depends in
           part: are you talking about "typical traffic" or against a hostile
           attacker. a hostile attacker can kill you. "typical traffic" is
           do-able but once you are beyond the throw money at the problem
           in terms of buying cpu and memory, this is kind of a black art
           involving hacking your net dev driver and perhaps your bpf filters.
           a lot of ids systems are freebsd boxen on gige. btw, trying to do
           this on a sysV machine is probably not possible. i dont know enough
           about linux to have an opinion there. --psb
