8/16    I just left my employer. They didn't ask to get their HW back.
        Is is common for employers to contact me a few months/years later
        and ask for their HW back?
        \_ Is it an iPhone 9 prototype? :-)
           \_ as a matter of fact, it is just a 2 year old laptop
              and they don't seem to keep track of inventor
        \_ You're responsible for returning your employer's property when you
           leave.  Consider the downside of them realizing it's missing and
           taking legal action (unlikely, but it does happen).  Is a two year
           old laptop worth *that*?  Granted, that's a worst-possible-outcome.
           \_ how much does a 2 year old laptop depreciate by? how much does
              it cost to start a lawsuit?
              \_ How much is your reputation worth? I worked at a failing
                 startup where a number of employees stole equipment.
                 I can guarantee you that they will never get a job at
                 any company I am working at.
              \_ You've misunderstood.  It's not the cost of a lawsuit.  It's
                 the cost to swear out a criminal complaint, and that's near
                 zero.  If a former employer wants to be a hardass about this,
                 they report the equipment stolen, swear out a complaint, the
                 police get a search warrant, and come looking for it.  If they
                 find it, it's a criminal case against you, not a civil case.
                 So it doesn't cost your employer *anything*.  It might not
                 even be your former manager, just some beancounter in finance.
                 In the case of failed startups, it's the outsourced
                 liquidation specialists (Diablo Management and their ilk).
                 \_ how about this scenario: They don't find anything in your
                    house. Someone blogs about it. It gets on Techcrunch and
                    Business Insider. Now the company is forever known as the
                    fucking lame vindictive asshole that nobody wants to work for.
                    fucking lame vindictive asshole that nobody wants to work
                    \_ Still not worth the risk to me.  The value of stealing
                       a two year old laptop is less than a day's pay.  That's
                       an absurd amount of risk for such a small payoff.
                       \_ According to taxman, equipments write-off depreciation
                          is about 20% a year over 5 years. So a $3000 laptop
                          is worth about $1800 after 2 years. You make that
                          much in a day? You serious?
                          \_ 20% a year is not realistic for computers --
                             you can't buy a $1000 laptop new and sell it a
                             year later for $800.  Also, most laptops are a
                             lot cheaper than $3000 new.
                          \_ The last time I talked to our finance people, we
                             were fully depreciating *computer equipment* in
                             three years, not five.  And it looks like our
                             typical laptops are more like $1,700.  Do I make
                             more than 1700/3 in a day?  Hell yes.

7/8     Suppose I just stopped going to work and stopped communicating
        with them. How many days will it take before they stop sending me
        paycheck (and maybe even try to get back the laptop they gave me)?
        \_ They'll probably try to call your emergency contact first to see if
           you're hit a tree or something.
           you've hit a tree or something.
        \_ this was much more amusing when I read it as "So I just stopped..."

12/21   In Emacs, how do I make it so that it will resize its screen
        when the maximum resolution of my monitor changes? When I
        use my laptop, my emacs is too big (and I can't resize it
        because the bottom-right corner is not accessible).
        \_ Which OS?  Can't you drag the top border (not a corner) to resize
           the height to be smaller?
           \_ MacOS 10.7, bottom right only.
              \_ How about "M-x eval-expression (set-screen-height
                 <some number>)"?  You'll have to type this without seeing
                 the minibuffer.
                 \_ yes that works. I tried this at home (when
                    my screen is downsized from a 24" work monitor
                    to my laptop) and had to do this blind without
                    seeing the mini buffer and had to do it a few
                    times. I guess I should learn how to write
                    a keyboard shortcut in elisp :(
              \_ Can't you drag/move windows by any border, or am I thinking
                 of a different OS?

3/12    I am curious what others think of tablets like iPad. They don't seem
        useful to me, but I use my computer for more than web browsing,
        Facebook, and Twitter. Why would I buy one instead of a laptop?
        They seem like a disabled laptop to me, but at a higher price.
        \_ You are most likely a coder.  iPad is not for coders.  They are
           what you get your non-technical friends.  Or musicians.  Look at
           the amplitude app.  Saves a tonne of gear shlepping.  Wolfram Alpha,
           etc: and
           And i'm not even going into how i used mine to replace a shelf of
           technical books that I realized were kinda annoying without an
           automated grep mechanism.  But to write code on?  never.
        \_ - this is a replacement newspaper for upper
           management.  The guys with the families, with the mistresses the
           100k/yr golf memberships etc.  EG. not you.  They would like to
           replace their daily printed reports with the latest in male jewelry
           and hey if they can get interactive graphs showing your coding
           teams' productivity whilst on the golf course in real time
           so much the better.
           \_ Lol i remember reading these 70s fiction books about "electronic
              \_ Upper mgmt read those too, as twenny somethings.  Natch, they
                 want ipads now.
        \_ I am curious what other think of cookers like the microwave. They
           don't seem useful to me, but I use my oven for more than heating up
           leftovers, boiling water, and making brownies. Why would I buy one
           instead of an oven? They seem like a disabled oven to me, but at a
           higher price.
           \_ microwave owners would trade good tasting food for a quick meal.
              if you're making fun of the poster not understanding that
              different users have different computing needs I'm right with you
           \_ Interestingly, I don't own a microwave either for exactly those
              reasons. I don't find it useful for cooking anything I would
              want to eat. It's an unnecessary expense and takes up
              counter space. Mine (received as a gift) broke a few years back
              and I have no desire to replace it. I would buy an iPad if
              it cost a lot less than a laptop, but it costs the same.
              Would you buy a microwave if it cost the same as a range?
              \_ define what you want the ipad for? and what you want the laptop
        \_ Here, these popular programs might show you who wants to use iPads:

4/4     My macbook is dying. After three and a half years, I want to retire it,
        and get a new one, but I live in constant fear* that Apple will pull a fast
        one on me and update them as soon as I do. Anyone know anything about an
        impending Apple laptop refresh?
        * = hyperbole
        \_ I also need a new Mac laptop and I am waiting for an i7-based
           system. I am hoping these are out soon.

1/22    looking to buy a new development laptop
        needs ssdrive, >6 hr possible batt life, and runs linux reasonably
        Anyone have a recommendation? Thx.
        \_ thinkpad t23 w ssdrive and battery inplace of drive bay
        \_ Ever wondered what RICHARD STALLMAN uses for a laptop?  Well,
           wonder no more!
        \_ Apple makes the best laptops, IMO.
           \_ always disliked apple laptops. no pageup/down key, too heavy,
              have that silly apple light on the back of the display, and
              don't offer an extended-life battery as a mfg option --!OP
              \_ My MacBook Pro has pageup/down. I find some of the laptops
                 like the Air to be really light. Battery life also tends
                 to be pretty good compared to the Dells and ThinkPads I
                 have owned. I buy new 2 laptops every three years (one
                 Mac and one PC) and I far prefer the Mac.
                 \_ real page up/down or fn up/down
           \_ and you can run Parallels or VMWare and still get Winblows
              and/or Linux, which is really really awesome. Plus, you
              don't have to worry about having to reboot your Winblows
              every few days. You really get what you pay for.
                                -20 year PC user, 1 year HAPPY Mac user
              \_ why does every mac user say 'run parallels'?
                 why not just boot to a linux partition? -- !OP
                 \_ I recommend using a VM, but not Parallels. The reason
                    is that its far more convenient than booting another
                    partition. It's much nicer to be able to run both OS
                    at once.
                    \_ seconded, but that's because I run both a PC
                       and Mac and VM images are universal on both.
                       If I run Parallels, then I'm stuck in Mac OS land
                 \_ spoken like someone who never ran a VM. I can run
                    multiple OS's at the same time with only 5-8% penalty
                    in run-time (if the application isn't graphics oriented
                    like games). Obviously, if you're playing games, then
                    you need to run natively. But if you're doing web
                    or backend development, running OSs in parallel
                    is a godsend because I depend on apps that exist on
                    PC (shareware), Mac (Photoshop), and Linux (compiler,
                    apache, editor)
                    \_ Not a stranger to VMs, but certainly do not want my
                       long-uptime linux and freebsd work environments running
                       on something as unreliable as OS X.
                       \_ I hope you don't have a raid hooked up to it,
                          the upgrade from 10.4 to 10.5 hosed my raid.
                    \_ I run linux on my older ibook.  PPC tho. Screw osx
                       pkg management is crap.
                       \_ oh wow, ok. America is great! Vote for GWB!!!
              \_ I did look at those and they didn't have the battery life
                 they seem to die out around 4-5 hours of use, and I mean
                 compiling, debugging, etc.  I'd like something that doesn't
                 die over a long flight (say to EU).
                 \_ Ok, what PC today lasts 6 hours of compilation?
                    \_ I get a good 6 hours work done on my current machine:
               (portege r500, ssdrive)
                       Been using it fairly heavily day in and day out 16/7
                       for the last 3 years and the mobo is starting to have
                       problems recharging the batt.  And heh, the keyboard
                       letters have all worn off.
                 \_ Get a spare battery.  Dell laptops let you use an oversize
                    battery instead of carrying a spare battery.
                    \_ yeah oversized and spare batts are the way to go,
                       i don't think mac supports swapping batteries for
                       extending life :-(.
                       \_ You sure can switch batteries. I have three for
                          my Mac. Are you sure you know anything about Macs?
                          \_ How do you force it to hibernate so you can swap?
                             \_ Close lid, wait a few seconds. Or press the
                                power button and select Sleep. Or select Sleep
                                from the Apple menu.
                                \_ Sleep != Hibernate.  If you put your Apple
                                   laptop to sleep and remove the battery,
                                   you lose your session.  You can make
                                   them hibernate with energy saver setting
                                   tweaks, but the hibernate mode is
                                   very slow compared to PC laptops.  -tom
                                   \_ Actually, it is, and you don't. (I just
                                      tried it to be sure.) If you put the
                                      machine to sleep, pull out the battery,
                                      then put the battery back in, it takes
                                      a while longer to resume, but you don't
                                      lose your session. The same happens if
                                      your battery runs down while the laptop
                                      is on standby.
                          \_ Non detacheable battery?
                          \_ The new macbook pros are internal battery only,
                             but that is irrelevant, because...
                             there is still no extended battery option.
                             Why carry multiple batteries and have to power
                             down/switch batteries instead of having a single
                             heavier battery that lasts the entire flight?
                             I don't see the advantage.
                        \_ I get almost 7 or 8 hours of compute time on
                           my new macbook pro.  I guess I could whine and
                           wish it lasted longer and that I could fit in
                           another battery, but I will chill.  7 hours
                           is a long time.
                             \_ fair enough. What PC do you prefer? Toshiba?

10/24   How well do you see color? I got 8, how about you?
        \_ 7
           \_ what monitor did you use?
              \_ LCD on thinkpad x32, under not so great lighting conditions.
        \_ I scored 101, which seems impossible. Then again, I didn't
           waste a lot of time to get it "just right". If the colors
           were in the same general hue I just left "as is". My gf scored
           \_ impossible because you're perfect but got an imperfect score?
              \_ Impossible because I certainly lined the hues up reasonably
                 well and yet everyone on here is scoring single digits. I
                 wouldn't say that I should necessarily score as well,
                 because I didn't give enough of a crap to pore over each
                 tile compared to the tile next to it, but I did sort the
                 tiles according to hue and shade (light pinks,dark
                 \_ I guess that's why you got a worse score?
                 tiles according to hue and shade (light pinks, dark
                 purples,etc.). I find it odd that we are scoring over 50 when
                 everyone else here is scoring 10 or lower. How does the
                 scoring work? How much time did you spend to get it
                 "just right"? I did the test in about 6 minutes (2 minutes
                 per row) on my Mac laptop. How much time did you spend?
                 \_ I spent 10 minutes and got 8, my gf spent maybe

                    Do you think you are a god given perfect person?
                    \_ Impossible that we would *both* score so low when
                       everyone else is scoring so high. Maybe I should
                       have said "Improbable".
                 \_ I got an 8 and I spent about 10 minutes on it total.
                    Since your g/f got a similar score, maybe it is your
                    \_ Maybe, or the lighting conditions. I am still curious
                       how this is scored. What does each point correlate
                       to? If I reverse two tiles but they are in the
                       correct slots how is that scored differently from
                       having them in the wrong slots? If you start with
                       a perfect layout and move the tile at the far right
                       into the middle then how is your score affected
                       versus reversing the middle two tiles? In both cases
                       you are 99% correct in arranging the tiles in order
                       but I imagine the former scores worse. I suspect some
                       flaw in the scoring algorithm to be honest.
                       FWIW, I just retook the test and timed myself. I took
                       6 minutes 19 seconds and scored a "3" this time on my
                       monitor at work. WTF?!? I call shenanigans.
                       \_ Since something like 10 people took it and had no
                          problem, the issue is probably not related to the
                          test itself.
                          \_ It very well could be. 10 is not a large sample
                             size. Maybe the scoring is not very fluid.
                             The distributions we are seeing tend to
                             suggest that: no scores in the 20s for instance.
                             What separates a "3" from an "8"? How wrong
                             do you have to be to score a "100" versus a
                             "3"? To me that seems extremely wrong. Even
                             if the monitor was not accurate I was matching
                             inaccurate colors against each other. I can
                             think of lots of reasons internal to the test
                             why I'd witness this, including that the site
                             was effed up for a period of time.

                    \_ I know because two of my coworkers are colorblind
                       and they often rely on me to distinguish colors:
                       particularly green from yellow. They have never screwed
                       something up by relying on my color judgement, so I
                       know I am not colorblind.

                          a perfect pitch when they don't even have good
                          relative pitch.
                 \_ colorblindness is not a matter of yes or no, it's a
                    matter of degree. It's not a "yes I can see all colors"
                    or "no I can only see black/white." It's a question of
                    how well you are equipped to see. We've established
                    that you're not colorblind, but also you're not
                    color-perfect either. If your work isn't in the arts,
                    don't sweat it buddy. You know, I felt bad that I didn't
                    have perfect pitch but that didn't stop me from learning
                    music theory and playing in the orchestra. There were
                    musicians who were simply equipped with amazing ears
                    and it's clear that god simply didn't bless me with
                    the gift of music, but I still have fun now and then.

5/22    Are LED monitors much better than LCD monitors?
        \_ OLED is still too new to know.  They're direct emitters, so don't
           have a backlight, and can turn completely off, hence better black.
           The early news was that blue pixels burn out relatively quickly.
           \_ FWIW, Zune HD will use OLED.
        \_ Dunno, but I saw a very nice LED TV for just $2K. Wouldn't that
           pretty much completely kill LCD and plasma and that price?
           \_ LED (not OLED) monitors means it's an LCD monitor with
              an LED backlight (as opposed to older monitors which had
              a florenscent backlight).  LED backlights look better, are
           \_ LED (not OLED) monitor means it's an LCD monitor with
              an LED backlight (as opposed to older monitors which have
              florenscent backlights).  LED backlights look better, are
              stronger, and last last longer than florescents, and are
              quickly becoming the standard for anything but the cheapest
              of displays.  OLED tech is much more cutting edge/expensive
              and high resolution displays are still crazy expensive.
              \_ I see. I was wondering because I saw an "LED TV" for $10K
                 just a few months ago and now they are $2K, but the
                 former was probably OLED and the latter is definitely LED.
                 I still use CRTs, man, and my TV has an analog tuner and
                 no cable, which means I have no TV in about 3 weeks.

5/6     My new Dell UltraSharp 2408WFP finally arrived. While it's only
        1/2 the cost of an Apple LED Cinema Display 24, it has very rich
        colors and is super bright. However, it is HUGE. It's about 5 inches
        thick and looks uber ugly on my little desk. Functionally, it
        does what it does well, and the specifications are superb. But
        it's like a PC-- full of features (CF card, SD card, 4 USB, VGA,
        displayport, DVI), 110% color gamut, etc etc etc. Yes on paper the
        specs look good. But it is nothing compared to Apple's 24 inch.
        I still think the Apple color looks better. More eye pleasing,
        less strains on the eyes, more crisp text display, more accurate
        colors. If it weren't for the fact that I can't do DVI->displayport,
        I'd get an Apple. Dell 2408WFP-- looks good on paper, but it's
        like a typical PC, loaded with features but lacks substance. I
        guess I'll just use this POS until I get a new laptop with
        displayport built in.
        \_ Dell brightness really hurts:
           Total piece of shit.
        \_ I have a dell 2405FPW, its an older model, I've had it almost 2
           years now, and it is still doing great.  It looks fine and I
           actually use the USB and CF slots in it.  I dismiss you as an
           apple fanboi.
           \_ No. The Dell is to the Zune as Apple Cinema is to iPhone.
              If you can't tell the difference, good for you. But to
              me, the Dell is just harsh on the eyes and badly built. By
              the way I'm not trying to insult you. Some people can't tell
              the difference between Merlot and Cabernet, and some people
              don't care. I don't know which category you fall into, but
              I can tell the difference, and I care. To each his own.
              \_ I think you mean the Dell is to Apple Cinema as the
                 Zune is to the iPhone.  The Dell compares to the Cinema
                 display, the Zune compares to the iPhone.  Back to the SAT
                 prep classes with you.
              \_ This is a terrible analogy on so many levels. For starters,
                 the Zune isn't a phone. So an iPod would be a better analogy.
                 But the iPod is not just an output device, there are actual
                 usability components, so it's not just straight technical
                 specs, industrial design, or quality of components to compare.
                 I work at Apple and like my 23" cinema display at work, but
                 at home I have a Dell 2005FPW and it's quite fine. OTOH, I
                 don't know how much you'd have to pay me to use a Zune.
           \_ I had a 2405 years ago.  I replaced it with an Eizo model
              within a couple of weeks and never looked back.  It's not
              just about the LCD panel (same Samsung panel in both).  The
              thing is cheaply designed using cheap components.  Lamp
              driver or some other high frequency switching circuit in it
              was emitting annoying high-pitched sound.  It was
              completely unacceptable to me.  Apparently, a lot of people
              are deaf thanks to the kinds and methods of music listening
              these days and can't hear it.  FYI, if I knew Eizo was
              going to release a 24" model within weeks of my 2405
              purchase, I wouldn't have even considered the Dell.
           \_ I have an Apple 23" and compared to my brother's 24" Dell,
              images on the Apple look better.  Still, if I had to replace
              my 23", I'd go with the Dell b/c it is so much cheaper. (I
              would probably have bought a Dell 24" in the first place, but
              I managed to get a huge discount on the Apple, so I got it

5/2     I have a 1Gbps switch. It is connected to a SANS RAID-1 with
        two WD Green 1T that takes 1Gbps connection, as well as a laptop
        that is also 1Gbps. Online benchmarks show *sustained* transfer
        rate of about 1/2 of 1Gbps with the WD Green... cool!!! But
        in practice, I'm only getting 68Mbps (read SANS->PC file transfer),
        far below what I expected. The switch says both devices are using
        1Gbps. BTW, setting the SANS on Jumble Frame/no jumble doesn't
        change the transfer rate at all. What's going on?
        \_ Are you limited by your PC's drive speed? 68 Mbps is 8.5 MB/s
           which may be all your drive can do. What do you get copying
           data on your drive locally?

              by my drive.
              That's 796*2 / 56 = 28MB/sec. So I hardly think I'm limited
              by my drive. I'm almost certain the bottleneck is due to
              something stupid I did, but seriously, I checked that NAS

              my laptop transfer speed is super fast at work. Reallly
              \_ Your drive can't do any better than 224 Mbps. Less over
                 the network given the overhead. Figure maybe 0.66 of 224
                 for 135 Mbps. That's only a factor of two different from
                 what you are seeing. Maybe there is some caching going on
                 to give you that 2x. If the NAS is *really* capable of
                 500 Mbps (which is what my $100K Netapp striped across
                 many disks can do so it seems unlikely) then I'd look to
                 your drive or your network card. Could also be that your
                 switch sucks. Try to connect with a crossover cable to
                 see if that helps.
        \_ What is the Sustained Transfer Rate for the disks in your NAS?
           Odd are it is about 25MBps/per disk. How wide is your stripe?

           \_ How is this the case for desktops but not laptops?  I don't see
              how turning something off at the end of the day would cause a
              problem.  Seems like less wear and tear.
              \_ It's more wear and tear to power cycle and lubricants get
                 cold. Your system will fail more quickly if you turn it
                 off every night in my experience.
                 How laptops are different:
                 1. Their h/w is better designed for low or no power.
                 2. They are much better about sleep/wakeup than desktops,
                    in part because of 1.
                 3. If a laptop dies it's not usually a big deal because
                    they are not expected up 100% of the time anyway.
                 \_ Here you go. Welcome to the 21st century.
                    \_ From a link found in one of your links:
"[Temperature cycling] is a well-established failure mechanism and a
stress on components," McCredie pointed out. "What it really comes down to
is all these things -- chips soldered on modules, soldered on boards and
connectors -- that expand and contract when they heat and cool.... When
they all contract and expand at different rates, they can fail. That's
ultimately the bad thing with power cycling," he said.
--Brad McCredie, an IBM fellow for the Systems and Technology Group
                        You can say "Cycling power on a sick system is
                        going to bring attention to latent component
                        weaknesses that go unnoticed in operation" which
                        maximizes "server availability", but that's an odd
                        way of looking at it. If you don't power down the
                        system then you won't have the failure and your
                        availability will be greater. I have gone through
                        just a few dozen exercises where equipment in an
                        entire data center was powered down and equipment
                        always fails at a much higher rate when that
                        happens. Whether it's just highlighting a latent
                        sickness is semantics. If you don't power it off,
                        then it won't fail, even if the power off is not
                        the root cause.
                        \_ Well, if you want to cling onto any comment
                           as a way to rationalize your practices, that's
                                \_ why give this guy a pass?  Fuck that!

                           The way I synthesize everything is if
                           you're not power-cycling a lot, you'll very
                           likely be fine for the useful life of the
                           product. It's a tradeoff between perceived
                           higher failure rates, which may go up "negligibly"
                           with occasional power cycling, versus the cost
                           to your pocketbook and the environment of running
                           hardware 24/7 even when it's not being used.
                           There are multiple comments that suggest that
                           turning off your equipment at night (or whenever
                           it won't be used for an extended period of time)
                           is the better tradeoff, but of course you
                           conveniently ignore those points.
                           P.S. A datacenter is a very different use case
                           than a typical home or work desktop. Although
                           powering down parts of a datacenter would still
                           appear to be much more a logistical problem than
                           a hardware failure problem.
                           \_ Different use case, but basically same
                              components. If they fail measurably (not
                              "negligibly") in that case then they will
                              fail at your home, too. Most people probably
                              do not notice because a 1/N failure rate
                              means you will likely be fine, but when the
                              number of machines is 1000N it's a noticeable
                              issue. I always count on a power outage to
                              result in dead hardware. You can make the
                              argument that a 5-10% chance of failure (say)
                              over the lifetime of the system is low, but
                              I'd rather just keep my system up. The key
                              point here is not that I am against powering
                              off equipment, but realize it comes with a
                              non-negligible risk of failure. Given my
                              experiences I just keep my equipment powered
                              on. As far as being environmentally aware,
                              maybe you should talk to the people in the 55
                              story buildings who leave the lights on all
                              night. Go anywhere in SF, LA, or NYC
                              to see that lots of lights are not on sensors.
                              Those "spectacular city views" are wasting a
                              lot of $$$.
                              \_ well, if you have control of the lights
                                 in the skyscrapers, by all means, turn
                                 them off when not in use.  If you don't,
                                 you should make wise choices about the
                                 things you do control.  -tom

                                       contrary. It's not a case of comparing

                                       and saying that I can replace the

                                       more power to you. My experience has
                                       shown that IBM guy (who *you* ignore)
                                       is correct and power cycling systems
                                       results in failures. You know that
                                       server in the corner that no one knows
                                       what it does exactly but is VERY
                                       IMPORTANT and the guy who built the
                                       s/w that runs on it - and only on
                                       that very h/w - left 15 years ago?
                                       DON'T TURN IT OFF OR REBOOT IT.
                                       Now, if you understand why that is a

                                       because the same physics are at work.
                                       Now if a h/w failure is meaningless to

                                       and power down, but that's analyzing
                                       risk/reward which is not the same as
                                       saying there is no problem with
                                       powering your system down. There is.

                                          your plan for handling the failure
                                          of a VERY IMPORTANT system is to

                                             keep turning it on and off every
                                             day, whether that's because
                                             the components are stressed
                                             or just because latent failures
                                             materialize. I know HP said
                                             that the h/w won't, but I
                                             doubt they tested systems

                                             experience has shown that h/w
                                             will fail when powered down
                                             and I dread it whenever

                                             because it means something is
                                             going to die. Sure, sometimes
                                             h/w dies anyway but it's
                                             *guaranteed* something will
                                             die when everything has been
                                             powered off. I have seen this

1/13    I've been using Ubuntu as my primary laptop for 3-4 month.  But there
        are still alot of things i need to learn... for example, after an
        application crashes, where do I look for any sort of logs that might
        give me a clue what happened?  how linux monitor the crashes?  So far,
        i had two bad episode of thunderbird trying to log onto my company's
        remote LDAP server and actually crashed the entire system... (as if
        some pull the battery out of my laptop kind of crash).  what kind of
        logs do I look for?  Also, when i type dmesg, what text file does it
        display?  thanks
        \_ If your whole system is crashing, that's a kernel problem,
           not anything related to your applications.  Start by running
           "cat /proc/sys/kernel/tainted" to see whether you're using
           any unsupported proprietary drivers.
           (It sounds like your problem isn't related to applications,
           but if you ever do want to debug an application crash, you
           can enable core dumps by adding the line "ulimit -c unlimited"
           to your .gnomerc file.  It'll take effect next time you log
           in; after that, when any application crashes, it'll leave a
           file called "core" in its current directory.  You can debug
           it by running "gdb application core".)
           The data that dmesg displays comes directly from the kernel
           (not from a file on disk), but it's logged in /var/log/dmesg.

12/7    What kind of adapter do I need on my Thinkpad to drive that new 30"
        Apple Cinema display?
        \_ New? Well, though I didn't know there's a new model, I'm pretty sure
           that like the old one, you'll need something with Dual-link DVI, or
           if they moved to DisplayPort (or whatever its name was), you'll need
           that. Basically, with such a large monitor, it needs a lot of
           bandwidth to get the signal over without a crappy resolution or
           framerate. So unless you have a pretty nice graphics adapter on your
           thinkpad, you won't be able to get the full benefit from it. If you
           don't have even a single-link (standard) DVI port, you're double-
           screwed, and won't be able to use it at all. --t
           \_ I did a bit more research and my Thinkpad only drives up to
              1920xXXXX so it's not going to use up the entire 2XXXxXXXX
              resolution that the new 30" native resolution has. Also it's
              a shitload outa my price range. I'm now thinking about the
              regular 24" with 1920xXXXX resolution. I only need a DVI
              \_ Yeah, if your Thinkpad hs DVI you should be golden. However, do
                 consider getting some other brand if you're not looking to get
                 the 30" model, as you'll save a lot of money without

12/6    I got my g1 phone to provide my laptop with internet access.
        It wasn't too painful.
        \_ throw enough money at a problem and it gets solved
        \_ was it real protocol-independent internet access, or were you just
           using the phone as a web proxy?
           \_ Tetherbot on the g1 creates a socks proxy
             \_ meaning if you want to run non-proxy-aware apps on your laptop
                its useless.   Still waiting...
                \_ It's trivial to run network aware programs through a proxy
                   in linux and macos
                \_ what are these non proxy aware apps ?  give me an example

11/11   I have laptop running linux.  Can I buy a G1 and tether them to
        \_ are you this guy
        \_ afaik, G1 doesn't do tethering at all, no app support.

10/20   Do people in photographic or graphic arts or advertising industries
        use LCD monitors?  When my Samsung SyncMaster 204B displays a picture
        or some color graphics, the colors change when I move my head around
        the monitor.  I don't remember seeing this problem when I had a CRT.
        How do people in the above fields use LCD monitors when color precision
        is extermely important?  Thx.
        \_ you want a display with good viewing angles.  I used to know all
           the terminology.  Good viewing angles don't necessarily give you
           accurate colors.  Visit, Displays.  You will pay more.
           \_ LCD guru, are Macs better for these type of things? I think
              Macs in general have more vibrant colors, but I don't know
              how accurate they are.
              \_ The difference can be pretty dramatic.  Go to a Costco or Best
                 Buy and check out the viewing angles.  Then go to an Apple
                 store.  Seeing is believing.
              \_ google for color reproduction cinema
        \_ I don't know about now, but in the recent past (say 4-5 years
           ago) they did not use LCDs in favor of CRTs. No idea how that
           has changed over the years, though.
        \_ I worked for a game company and all the illustrators and graphic
           artists had CRTs while the rest of the company had LCDs.

9/18    My  7 year old Dell laptop is slowly  decending into its death throws.
        I am seriously considering an Mac laptop; but am having a hard time deaa\
        ling with the price. Curious to find out  if people really think that
        the extra $$ upfront was a good investment. a 2K macbook pro with
        standard config can buy a high end dell laptop
        \_ I have both a MacBook Pro (and before that a PowerBook) and a
           Dell Latitude. I love Apple laptops. The only other laptop
           I might consider are the ultra lightweight Acer Netbook style
           laptops. The Dell is clunky and feature poor. It's also nice to
           be able to run both MacOS (I like UNIX-style command line) and
           Windows XP (using VMWare).
        \_ Have you considered a MacBook? It is much cheaper than the MBP
           and almost as good for most things.  The only thing I dislike
           about my MB is the integrated graphics.  In all other aspects,
           it is the best and most reliable laptop I have ever owned.

8/27    I have a rather large linux partition.  I just got a new laptop
        and want to move all my settings and customization to that new
        computer.  how to do this?  I tried remastersys but it seems that it
        get stuck somewhere, and I am hoping it is not really trying to create
        a 26GB iso file.
        any ideas?  is there anyway i can back up my debian package database
        and do it that way?   i am running Ubuntu Hardy.   Thanks
        \_ Put both drives on a network and use rsync on the filesystem.
        \_ When I was a POW, partitions had US!
