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:
http://www.theinquirer.net/?article=26127
And then their advertising against Dell:
http://www.theinquirer.net/?article=26164
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."
http://thomer.com/vi/vi.html
\- 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
distribution.
\_ 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>psb.is.a.moron<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

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.

\_ Price/performance is much better for the Pentium D than the
dual-core Opterons. You can heat rooms better, too.

or 3800+ for $405 per CPU. Desktop. |

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
\_ http://news.com.com/2100-7341_3-5733756.html
"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
machines?
\_ 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
technology.
\_ 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:
http://csua.org/u/cae (adc)
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. |

6/6 Apple to use Intel chips. Does this mean future iBooks will run as
hot and as short as Intel Pentium M based notebooks?
\_ I think a strong motivating factor behind this decision was that
IBM cannot seem to make the G5 viable at all for laptops. |

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.
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:
http://www.daemonology.net/hyperthreading-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. |

\_ 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.
\_ I build my own now. I enjoy doing it and once
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
http://cnet.com as very quiet, due to its new BTX case design (which
funnels air down a central corridor as my Geek Squad friend
tells me). http://csua.org/u/c2w
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 http://slickdeals.net for
a good deal to come up.
\_ http://endpcnoise.com has great parts and complete custom systems.

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
date.
\_ Thanks for erasing my post and adding bullshit at the same
time.
\_ it's ok, I read it already. -- OP
\_ that is why I post this on motd. If i think i am in a
position of being objective, i probably can make assessment
on my own. having said that, from little things such as
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.
Usability is actually pretty decent. -John
\_ 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
meaningless.
\_ 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 http://silentpcreview.com are
specific models of the (Panasonic) Panaflo. I got one last week,
it's quiet and pushes medium-amount of air:
http://www2.newegg.com/Product/Product.asp?Item=N82E16835180041
I got the Vantec 80mm below but it clacks and is annoying:
(probably only mine sucks - poor quality control)
http://www2.newegg.com/Product/Product.asp?Item=N82E16811999602
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:
http://www2.newegg.com/Product/Product.asp?Item=N82E16817103458
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
perceived loudness by 2x.
\_ I got my Papst fans from http://quietpcusa.com, 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:
http://www.quietpcusa.com/vgainstall.html
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 http://silentpcreview.com Excel file)
</sarcasm>
\_ 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,
damn. -chiry

you spend on it and do you think its worth it?
\_ If you want a quiet computer, it is most effective to tackle
all sources of noise at once. http://www.endpcnoise.com
\_ A colleague of mine bought a Zalman TN1500A, with a bunch of

sol'n is to use "setarch i386" on my Pentium M730 processor, and

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
cause 'program' to see i686 (or other relevant arch) instead of x86_64
as machine type. It also allows to set various personality options.

\_ What's the point of running TabletPC OS if the screen is not touch-
sensitive?
\_ 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
accurate to use. Is the Tablet PC for everyone? Absolutely NOT.
It tailers to a niche market, and will most likely never be
main stream. But I think it's cool -happy Tablet PC user
\_ 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
with your fingers anyway. |

\_ 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
bizarre, meaningless techno-babble advice often disgorged
on the motd. what happened to the CS in CSUA?
\_ 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
get higher efficiencies when transferring information to a
CD burner.

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

\_ 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
CPU.
\_ XP Home does not have IIS. Pro does for development purposes.
\_ M$ is really good at bundling things and defying antitrust laws.
\_ My gf wants a cheap laptop(against my advice.) Are there any
significant difference between Celeron M 360 and Pentium M 725?
Besides the cache I mean. I'm mainly interested in performance
and battery usage.
\_ http://www.tabletpcreviewspot.com/default.asp?newsID=178
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,
ebp.
\_ 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.
\_ They did try, and it went over like the Hindenberg (c.f.
IA-64)
\_ IA-64 sunk for other reasons. You don't need an
expensive 64-bit processor without a market in order to
allow some programs to execute the microcode (or some
one-to-one translation thereof) directly. |

--lye
\_ tell us about transmeta, like was it cool while you were there?
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
like a complete maniac.
--lye
\_ what kind of car did he drive? and is he a nice guy?
\_ Yellow Mercedes Benz SLK32 AMG. --lye
\_ Did Ditzel go down in flames too? I see that he's making $411K
a year, but did he manage to sell his stock in time?
\_ Ditzel was well equipped with all manner of golden parachutes.
While I was there, he typically unloaded 100s of thousands of
shares a month, which he was optioned at a very low price.
This is all a matter of public record, I believe. --lye
\_ I think this is a very good move, even if they don't make it.
The code morphing is very cool, I have always thought this would
be a great match for a next generation of high performance chips.
A brilliant way to help move away from the aweful x86 ISA. -jwm

\_ In case you were wondering, this response has gotten old, at

wouldn't use psb's "\-". And I don't think jwm is an
idiot. -tom
\_ dude, fuck off. What the hell is wrong with you anyway?
I didn't post with your username. It seems obvious
that erikred didn't either. Nor did I think it amusing
when someone did it in the middle of our thread.
-crebbs
\_ Doh! I should have thought of that. -- ulysses
\_ tom, I promise you, I have never nor would I ever post
under your name. I have a soft-spot for loveable cranks,
so I'm not likely to alter or delete your posts, either.
Keep on trucking. --erikred
\_ Tom is right on here, although he probably didn't need to
resort to insults. Code morphing is "cool," but essentially
useless. Is there a word for technolgy like this?
Slashdotware? --lye
\_ I recently suggested to google scholar that they add
an Erdos number calculator. -- ilyas
\_ That would fucking rock. Could you post if they
respond? I wonder if they would be more likely to do
it if they got more requests for it. The only time
I sent a suggestion to google(about their calculator)
it was totally ignored.
\_ What was your suggestion? I might be able to talk
to someone who can get it done.
\_ I made another suggestion to scholar a while back
that got put on a feature list, apparently.
-- ilyas
\_ I respect your opinion on this because you know
a great deal more than I do about this. To me it
seems that it could be very useful, and in fact
practical in the sense that it could be used to solve
real problems. But I am very interested in your take
on it as someone with experience. --jwm
\_ It's a very long story - but essentially code morphing,
no matter how good it is at individual benchmarks,
never "feels" like "real" hardware from the native
instruction set that you are emulating. Translation
time lag always leads to a jerkiness and the feeling
that the computer is "shifting gears." This is on
top of the fact that getting the translator to do the
right thing in all cases while optimizing for
performance is extremely hard. --lye
\_ Java is the term I use.

12/21 Hey fellow moderately rich bastards. The Samsung 193P is on sale at
http://jr.com for $500 after rebate. I just put in my order with next-day
shipping. See http://newegg.com or http://pricegrabber.com to see other prices.
http://www.jr.com/JRProductPage.process?Product=3967280
\_ How can it have a 4:3 AR with a native resolution of 1280x1024?
(And yes, I am aware of the existence of rectangular pixels, but
I was under the impression that no one sane makes LCDs with
non-square pixels.)
\_ I don't get what's so special about this monitor with the exception
of slightly higher contrast ratio. Am I missing something?
\_ http://www.xbitlabs.com/articles/other/display/lcd-guide.html
http://www.anandtech.com/displays/showdoc.aspx?i=2289
There is consensus that the 2001FP (20" Dell) is better still.
\_ Fully review here: http://www.anandtech.com/showdoc.aspx?i=2024&p=1
\_ It's not better except it's bigger. If you read the comments
on that monitor, 193P has better features and they rated it
higher in the "subjective" analysis.
\_ Yer right. I should say, "some say that" the 2001FP is
better still because it's 1600x1200 and has all the groovy
inputs.
\_ Full review here: http://www.anandtech.com/showdoc.aspx?i=2024&p=1
Note this comparison:
http://www.anandtech.com/showdoc.html?i=1974&p=7
\_ You can get the Dell 20" wide 2005fpw for $622. Don't
bother with the samsumg for $500. Check
http://www.techbargains.com for the coupon code. I am ordering
one, no rebates, no fuss, and 20". If you can afford $500,
you can afford $622, believe me, the difference between
$1600x1050 and 1280x1024 is big.
\_ Do you expect any problems with widescreen?
\_ I will let you know when I receive mine. :) So far I haven't
heard any problems with the wide screen. It works better for
DVDs and photos taken with digital SLR, you actually get more
pixels than 1600x1200 but shrinked....
\_ What happens when you want to drive it with a 2 yr old
notebook with Intel chipset graphics? (how does it
interpolate to 1680x1050?)
\_ I'm trying to decide this too... I could get this for $610
shipped with my coupons.
\_ Actually if you call Dell Small Business, they may
give you a 35% off coupon. That will bring the
overall price to ~ $560 shipped with tax. Hella of
a deal. Just ordered mine. The best price I can
find online is the 30% off for small business, but
with tax and shipping, which totals to about $620.
But you have to call them, as the $35% off coupon
is not listed anywhere. Check this thread

ordered my crappier deal and will call tomorrow to
bitch or cancel if I can't squeeze out any more money.
\_ What if the 193P is only $414 ?

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.
\_ heh, same with my younger brother's computer. He was mighty
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
sticks of CL3 Kingston 512MB work fine, but it has the same
problem with random games in the dynamic frequency-clocking
mode (I had to fix it to stay at 2.2 GHz).
\_ Where did he buy it from? Or did he assemble it
himself?
\_ Newegg, both DIMMs are the same - it's probably a flaky
mobo that worked fine with 512 MB but had problems going
to 1 GB at the spec'd speed
\_ maybe your northbridge could benefit from better cooling. |

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.
I don't know what else to try, is it a hardware failure of some type,
or maybe AGP apperture? This is a GeForceFX5700 on an Athlon XP.
\_ SP2? Running in safe mode works? Maybe bad memory? -John
\_ SP2. Can you use D3D in safe mode? Other apps are stable.
\_ SP2 fucks up a lot of apps and games. There are lists
of known problems at the MS site. I think there's a way
under safe mode to select the drivers you load. Just as
a terribly stupid idea, try setting up a vmware session and
running the game inside that--it might give you some more
clues. -John
\_ The SP2 issues page seems all about firewall issues,
which is not the problem. Safe mode, while a good idea,
prevents DirectX from working.
\_ I had some similar problems after I installed a new video card
in my old computer. Make sure you are not overloading your video
bus. Try turning down the AGP rate from 4X to 2X or even 1X and
then see if it still happens. I tried a bunch of things before
I hit upon this. You can set it in your start-up screen. -ausman
\_ Motherboard supports 2x and 4x. Switching to 2x did not fix it.
\_ Do you have the VIA chipset? I do, and I have the same
symptoms, as documented on <DEAD>viaarena.com<DEAD>. -ax
\_ MB is Abit KG7, with AMD 761 northbridge and VIA 686B south.
\_ What did you do about it? -ausman
\_ I got used to not being able to play the Medal of Honor
series. Most other 3D games work fine. -ax
\_ Could be something overheating.
\_ But Doom3 runs fine for hours.
\_ My younger brother had this exact problem after we added another
Corsair CL2 DIMM to get him to 1 GB. Entered BIOS settings and
turned CAS settings from Auto or CL2 to CL3 - now everything works
fine.
\_ 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.
-williamc
\_ 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.
-williamc
\_ 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
sending a corrupt instruction to the video
driver or AGP controller. Now if there's a
MB/chipset that is randomaly corrupting some
writes to main memory, a game which makes more
writes has more chances to get stung, and send
a corrupted instruction. Just one explanation.
\_ Yeah, but shouldn't that mean that he
should see Doom3 crashes sometimes as well?
Less frequently yes, but none at all?
Something else is happening that we are
not quite understanding here.
\_ RR Tycoon, Pirates, and Rome must have
something different about them than GTA,
Doom, and flightsim. Maybe he should try
underclocking his FSB and see if things
get more stable. Anyway the memtest
indicates the RAM is the problem area.
\_ Memtest doesn't report any problems,
it flat-out locks the system. This
is with 2 different RAM sticks. -op
\_ No, you're wrong. It's the MB, plain
and simple. Just because it appears
as if it's a memtest problem doesn't
mean it's not the MB. Trust me, it's
the MB. I have direct experience
with Abit K series MBs, I've seen
stuff like the IDE controller going
wonky, the serial ATA going wonky,
the video AGP problem going wonky,
etc. The memtest is only one
symptom of basically a chipset
problem. Hardware is complex, it's
not like software where you can
pinpoint stuff to one dll and say
the bug is there. It's the MB, stop
wasting time and just get it replaced.
It costs $50. -williamc
\_ Thanks for your help. What do you
think of this mobo:
http://tinyurl.com/4ul8f
\_ It looks fine, I've never had
an issue with nvidia chipset.
I've had some minor problems
with MSI, though, but that's
on the P4 side. Your athlon
should be fine as long as
you get a good board, MSI
makes decent (but not really
outstanding) boards. The
nvidia I have running an athlon
is an ASUS from last year.
-williamc
\_ Could also be the power
supply?
\_ Hardware monitor reports all
voltages 3-5% over spec. -op
\_ Sounds like a virus. Reformat and start over.

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

it, and no idea of the Berkeley environment. -tom

\_ As long as someone eventually beats Micro$oft, I don't care.
\_ and linux is going to do that?? hahahaah
\_ Incidentally, why do people rave about Ed Zander? What exactly
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
runs linux and does this. -Sun fan
\_ Any place that runs Linux on an AS400, dorkus. It's called IBM,
they are going Linux, it's well supported, and runs like a
charm.
\_ You know, administering 100 (likely similarly configured)
machines is not really _that_ hard for any competent sysadmin as
long as they run some form of *nix.
\_ Sun is out to destroy itself. Sun Service's new trick is to come
in, declare all the SA's overpaid, and replace them with Sun Service
H1-B's making $20/hr. -ax
\_ 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
looking at their education promotions page, and the best deal for
"low-end" server is a dual USIIIi rack box that costs $7000. Say
what? I can get a Dell twice as fast with storage 5 times the sun
for half the price. If that's the best they can offer, I feel really
really sorry for them. |

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
performance.
\_ 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!"
ad.
\_ 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. |

11/15 What's a good place to buy a custom computer online? I'm looking for
a high degree of configurability and a sane price. Dell is too
limiting, and Falcon Northwest is $$$.
\_ how is Dell limiting your configurability options?
\_ No ability to pick a motherboard, few AMD options, no choice of
component brands, few chances to get a 10kRPM drive, etc, etc...
\_ Thunderbox
\_ It seems they all look like rice-rockets.
I guess what I'm looking for is "If Newegg sold systems..."
\_ Company run by a white guy. Maybe he just has an Asian fetish
\_ I don't mean rice-rocket in the sense of souped-up asian
cars, but in the sense of computers built to *look* fast.
\_ How about Monarch? Dunno anything about their quality, though,
but their prices do look reasonable and they're very flexible
on the configs.
\_ I like http://sysbuilder.com and I've bought two computers through them now.
\_ Nice. Thanks. How's their customer service? -op
\_ From what people have told me they can be slow to
respond (they seem to be a pretty small operation), but
they will get around to you.
\_ I haven't tried them, but http://armsystems.com has quite the range
of configurability. They specialize in low-noise boxes. |

\_ What's wrong with Liebermann?
\_ He was one of the authors of the homeland security bill that
created the DHS, is a big supporter of the patriot act,
was part of the crusade to censor music and video games,
is owned outright be the insurance industry, and is a total
welfare whore for the ct. defense contractors. In the primaries
the candidates were asked about how to deal with America's
healthcare crisis. Everyone had some answer or another
except him. His response was basically "I don't think the
american people want to hear about that." Hell, even the
republicans admit our healthcare system is fucked, they just
disagree on how to fix it. When someone says it's just not
a problem, that's far far worse. As a ct. resident, I
particularly resent him because I've voted for him on a
lesser-of-evils basis, but he continually represents the
corporate interests of CT, rather than the people.
\_ So, to sum up, he's the biggest liberal in the Senate.

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 http://newegg.com 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.
Search the http://newegg.com reviews for any of the above CPUs if you want
suggested mobos + memory to buy with them. |

10/8 I am looking for a quiet case fan and cpu fan for my P4 2.26ghz
system. Any suggestions? I just realized the case fan and cpu fan
is significantly louder than my power supply. thx.
\_ A colleague of mine is getting a Zalman TNN500A
http://www.zalmanusa.com/usa/product/view.asp?idx=64&pr_name=500a
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
\_ Don't save $5. Buy all Zalman. You'll appreciate the quiet
everyday for years and won't miss the $5 later.
\_ Be careful which Zalman 90mm fans you buy, some are 25db
others are 19db. I haven't been able to find the 13db ones
anywhere local. |

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
politics. |
| 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
minifridge.
\_ 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
environment...
\_ 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!" |

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 do...as 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. |

9/3 Thinking about getting an opteron? If security is your concern,
maybe you should think again: http://csua.org/u/8x7
\_ 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.

\_ What about the AMD 64 processors? Is there any value in

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
system.
\_ 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
http://gotapex.com. 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.
\_ AMD! AMD IS THE STANDARD ENTHUSIAST CHIP!
\_ 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 |

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 number. \_ 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 \_ having worked there I can assure you that NO ONE there knows the inside scoop.

I am talking about what they will have available through 2006. -op \_ If you care about conserving energy, just turn off your desktop machines and monitors when you leave work. A few people turning off their machines and monitors after work saves a lot more energy than getting whatever low-wattage server you can find. \_ I'm concerned about the heat output in my data center. You're not getting a 3.6ghz machine on your desktop in my company. Also, many shops do desktop backups at night so turning off your machine is a no-no. |

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.

postfix could have been using the rest of the CPU. If these

4/12 Is is common but implicit in computer repair to use used but
*working* component to replace bad components on the unit you gave
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
wrong.
\_ 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. |

upgrading the main server without having something
substantially better. Lesser donations can be used on the

do not in any was represent the opinions of either the

\_ It's funny that someone calling others clown with no
justification talks about basic manner.
\_ If you don't see the justification you're beyond
hopeless.
\_ a better processor is not much use without a motherboard (and
everything else that entails) to support it. though frankly,
how much processing power can a machine used to read mail and
edit a text file need...
\_ But Intel makes mobos too. All you'd need is probably new RAM.
I don't know what type soda has now. We don't need the latest
greatest RAM so maybe the current stuff would work.
\_ uh, run uptime: 183 users, load averages: 1.29, 0.94, 1.00
\_ Your point?
\_ his point is that politburo is stingy on processing
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

3/8 I've finally got it so I can't hear anything at all from the 3
computers in my home office. I just got 4th one which is so incredibly
loud it completely drowns out the other 3!
\_ Get a new quiet power supply.
\_ Could be the CPU fan too. Anyway, newegg sells an Enlight 360 watt
for $25 which is quieter than the $60 PC Power & Cooling Silencers.
(Yeah, I have both.)
\_ It's a 1U server which has a vacuum cleaner volume fan that blows
over the fanless dual cpus and mb chip. It's so loud I can hear it
2 rooms aways with the door closed. Now that I have it on the net
I'm going to finish building it out remotely and then move all the
parts to a mid-tower and put a pair of $5 cpu fans in the case. It
is going to replace the mid tower which I'm still using so I can't
put it in the tower and then build it out. BTW, any suggestions
for *quiet* cpu fans for a 1.0 ghz p3? thanks! --op

There are typically 4 sources of computer noise:
1) case fan(s)
1) case fan
2) power supply fan

4) hard drive.
Fix all four and you'll be happy and able to think more clearly.

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. |

3/3 Dear Intel: Prescott is a Dog. AMD64 kicks your ass. Thank you for
playing anyway!
\_ Okay, we all know that Prescott runs 90 watts plus, but can
you provide a URL comparing performance of an AMD CPU vs. a
Prescott, in the $150-$250 price range of CPUs?
\_ Come on, try harder. Prescott isn't in that price range.
The 3.2ghz is $278, the 3.4ghz is $417. It might do alright
in benchmarks thanks to its cache improvements, but my
2.4ghz Northwood feels "snappier," and the AMD64 eats it for
breakfast.
\_ You need to start giving people a little more credit.
Prescott is in this price range. http://csua.org/u/69f
I just had to build a system last week for someone (it
was not a Prescott, but I looked at it), and the CPU I chose
was $183. I also see the Athlon 64 3000+ for $211. Are
there any diffs between the 3000+ and 3200+/3400+ other
than clock frequency? (Oh, I do see the increase in L2
cache from 512 KB to 1 MB; that must be why the 3200+ is
$270.)
\_ 3000 -> 3200 = +cache. 3200->3400 = 3000+cache+clock.
\_ thx.

\_ Answering my own question: http://csua.org/u/69h
FYI, the system I built last week was a Pentium 4 2.8C (800 Mhz
system bus, HT) with an Envision 360W power supply and an ATI
Radeon 9600 SE with an Asus P4P800 mobo. SATA 160 GB Hitachi

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
interference.
\_ 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. |

idea. We have a couple of dual opteron boxes at work (newisys)
they are very nice. No problems with Linux (SuSE Enterprise
Linux 8 and RH 3.0) or FreeBSD 5.2.

my habit is to just get a new computer every 5 years.

to ever put a new chip in that mb? By the time you're ready to
get a new chip, you'll *want* to get a new mb to get all the new

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. http://mersenne.org. 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. |

12/30 Three weeks ago I accidentally overclocked my AthlonXP 2000MHz to
2500MHz for 24 hours running setiathome. A test with memtest86
showed no errors, but since then, I've had three different disk
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
just figure it'd be fun to fry an expensive new chip?
\_ He said he'd done it accidentally.
\_ I had this EXACT same problem when I fried a memory stick.
Put a new RAM chip in and see if it goes away. Also, make
SURE that there is good air flow over the memory (I.e.. no
drive cables occluding the case air flow).
\_ I fried a mem as well. There were no smoke whatsoever, but
it's a goner forever. Overclocking ain't what it used to be
\_ I ran memtest86 for many hours w/o a single flaw. -op
\_ Really- just try to put in a new mem stick. In general,
don't trust software- Its a 10 minute experiment.

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.
\_ ah, you loose. just look at how this thread has grown.
\_ probably lose, too. we weren't talking about yermom.
\_ you mean the fact that it runs faster, runs cooler, costs less
and out performs Intel's best? hmmm, yeah, and no one will ever
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.
\_ Try 45 watts in the real world. See real world benchmarks
on your favorite website for faster.
\_ Are you talking about the desktop Athlon 64? Please
post a link to the 45W claim - I'm very interested.
I wasn't able to find any heat data beyond "89W" for
the Athlon 64 FX on tomshardware or anandtech.
And actually I also see 89W Thermal Design Power for
the FX, 3000+ and 3200+ on http://amd.com.
\_ Until MS Office 2005 ships with a minimum RAM
requirement > 4Gb thanks to the integration of
the Yukon database throughout.
\_ There's a conspiracy between M$ and Intel. M$ keeps
cranking out slower and slower software so that people
have to buy faster and faster CPUs.
\_ Well, maybe not a conspiracy.. Let's call it a
friendly mutual arrangement.
\_ Wasn't java more CPU speed demanding to offset java's
inherent slowness? Also, it's more Memory demanding.
\_ There isn't any new software that people care about
that needs much speed. Even new games don't need the
latest stuff.
\_ Doesn't matter, Microsoft & other makers
keep requiring more and more speed and
do as much as possible to make it hard
to continue using older versions with
lower requirements.
\_ NP-hard problems need speed.
\_ Indeed. What NP-hard problem is the mass market
so intent on solving?
\_ Now you deftly (?) went from 'people care
about' to 'mass market.' People care about
NP-hard problems, my friend. Otherwise
there wouldn't be a name for them.

a problem, though.
\_ how can you disconnect the PS from the MB and test it without
buying a special ATX PS tester? isn't an ATX PS dependent on

\_ 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
and 5) well, there's more but I've gotta go grab the new seti
client so I can cure cancer.
\_ 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. |

I'm not going to be slapping a ton of gear into this machine. The
board I'm thinking of getting is the EPIA CL10000 board. It has two

a compact flash to ide converter for the file system. Any other disk
space needed can be mounted off a central file server with samba if I
want. For logging I'll just use syslog-ng and log remotely.

8/10 I just build a AMD2500+ computer and overall I'm pretty happy with
it. However it seems to output a lot more heat than my P4. Is this
normal?
\_ yes AMD cpus consume more power and run hotter
\_ I hope you're not settling for a stock fan, and you have at least
2-3 case fans.
\_ 2 blowing in (with filter), 2 blowing out, and 1
circulating inside. It's still pretty... warm. Is it
mostly from the CPU? My MB has a fan for its chipset,
my AMD has a huge ass heat sink with fan, and even my
ATI All-In-Wonder Card has a fan.
Actually I'm kind of disappointed now with the
power consumption. Do AMD & Intel publish their power
(wattage) somewhere?
\_ Exhaust fans are generally more effective than
fans blowing in. I think it has to do with turbulence
fans blowing in. I think it has to do with turbulence
vs lamnar air flow. to get the heat out. AMD CPU's
chips are hotter.
vs lamnar air flow. to get the heat out.
\- hello, it's perhaps not intuitively obvious but
this is a case where you dont want completely
laminar flow. the pressure differential you can
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.
mirco design issues [like fan blade shape] as well
as macro ones [location of fans and components
demending on their heat properties ... tolerance
and production] is a big design problem. i used to
work on modeling flows at IBM Almaden. so in
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]
area to see real applications of theory/math. --psb
\_ Wow, interesting! Thanks.
\_ Did you design anything we would have heard
of or used?
\- I worked mostly on models and design tools

And may I ask why you thought the alien NASA question was particularly difficult that it should deserve special merit for finishing quickly? \- that's not what i meant about doing the pattern matching quickly ... i probably did lousy at that because i didnt spend much time on those. i dont think you can compare a 135 in 10 min and a 140 in 20 min. how much time you spend on the "which one doesnt belong" type Qs i think also makes a diff. --psb \_ I am not defending the validity of any test which claims to be able to categorize all of human intelligence with any accuracy or precision by asking 40 simple questions.

performance wise? Given the same clock speed which one is better?
Similiarly, I am looking for one notch above Pentium 3-M, does
AMD/VIA/Transmeda has chip that outperform p3M by a notch? it doesn't
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 buy a celeron for anything unless saving $5 *really* means
that much to you in which case you shouldn't be buying a computer
anyway.
\_ I am looking at IBM T-series versus the new IBM X-series.
I am using company's old IBM X and I am wondering how's
new IBM X (Pentium M) stack up against IBM T(Pentium 4M)
--OP
\_ 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 http://cnet.com. My impression is that
the Pentium M blows the AMD CPU out of the water in
performance and energy consumption. |

Really like the company IBM X-series. But X-series only uses
Pentium 3 processor. Is there any other notebook that is similiar
in size (e.g. 13" LCD) but use a CPU which is more powerful than
Intel P3? I don't mind CPU being slower than Intel P4, but I
want a notch above P3. What kind of Transmeta / AMD / VIA CPU
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.
\_ Turn on all the graphics and play at hi-res where the
developers intended you to play then come back and say
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: http://csua.org/u/3n9
\_ 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.
\_ http://csua.org/u/3na
\_ 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 $$$.
Warcraft 3, RtCW, and a few others.
\_ 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
getting playable frame rates. Maybe your idea
of playable is different from mine.

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.

12/8 Just exactly how fast is USB1.1 vs USB2?
\_ Isn't this highly googlable?
\_ You think we'll all think you're cool cuz you made up
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
this.
\_ 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: http://www.apple.com/xserve 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 http://corpsys.com 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 http://pixelusa.com. 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 server. \_ 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. \_ Mylex DAC960 controller. You can put together a real good x86 server for <<< $5k. Equivalent performance (and yes reliability) from Sun is gonna 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 \_ I don't want to 'put together' 20+ new boxes. \_ ah. nweaver. \_ what software robustness and support do they lose? only if you screw together some parts from Fry's. \_ You get incomplete and unstable NFS support and funky RAID software. See the original poster's requirements. 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 RAID. \- does apples weird file system with its weird case issues manifest themselves over nfs? this is a real annoyance for me when Makefile = makefile, configure = Configure etc. ok tnx. --psb \_ Forget software RAID anyway. Performance *is* an issue, although it may not be the determining issue. Buy yourself a hardware RAID card and stick it on a cheap PC with a gigabit NIC. --dim |

that does 333 MHz DDR and any cheap processor.

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
