5/6     Hi, I'm building my own Linux server from scratch. Can someone tell
        me what the approximate performance gain I would get by using two
        SCSI drives (one for kernel/binary/swap, the other one for user only)
        versus two EIDE-4 drives? There is a pretty sizable price gap. THANKS.
        \_ post to ucb.os.linux for access to clueful opinions
        \_ Serving what? With only two drives SCSI will most likely not gain
           enough of a performance advantage to justify the cost, unless you
           get 10000 rpm Ultra drives on a fast SCSI card or something. That
           said, I always buy SCSI for the flexibility it affords. EIDE
           is an icky PC hack. -dim
                \_ RAID!  (And yes EIDE is an icky hack but its ok for home)
           \_ I'm serving a heavy load web server (10000 hits per day) with
                                                        \_ that is NOT a heavy
                                                           load - that's less
                                                           than 1/second - a
                                                           286 can serve that
                                                           web load (might
                                                           need a 486 for the
                                                           cgi load)
              heavy CGI-scripting and Postgres. APPROXIMATELY what is the
              ball park performance gain I would get from SCSI vs. EIDE? THANKS
              \_ That's going to depend on which drives you are comparing,
                 which will matter much more than SCSI vs. EIDE. --dim
                \_ DUUUDE!  SEAGATE ELITE 23!!!  23 GIGS OF PURE P0WER!!!
        \_ Since SCSI can be better pipelined much easier, and does not
           load the CPU when accessing data, it is probably much more
           effective for a server machine.  For personal use, where
           most of the time you are only doing one thing at a time,
           it doesn't make a difference.
           \_ though if you want to multi boot, EIDE has really fucking
              annoying limits on what cylinders it can boot from.  just pay
              for the scsi.  you'll be happier

12/4    A question to you old crufy alumni: So lately we've suggested
        VMs, and been asked why it's necessary. We've suggested top-of-the-line
        hardware and been told we don't need that much power. So I'd like to
        ask -- what exactly do you think the CSUA is supposed to _be_?

           is newer than DNS-323 with less problems. It doesn't have as

8/4     I went to Fry's for the first time in ages and was surprised to
        see a 1T Seagate HD on sale. I'm still using my 250G and it's
        only 60% full. What the heck do people put on their HD these
        days, porn? I can't imagine why anyone would want to buy a
        1T drive for personal use.

11/15   So if I have a process running in Linux and kill -9 isn't
        killing it, and killing its parent process didn't kill it,
        and now it's reading as though its parent process is 1,
        is there any way to kill it short of rebooting the machine?
        \_ Sure, but you dont want to be mucking around in kernel data
           strucures.  Most practical way is to reboot the machine.

6/3     I find myself having to reinstall WinXP sp2 every 1 to 1.5 year
        due to sluggishness and problems (yes I've tried every single
        trick that you can Google for). I'm at a point where I think I
        should just install a fresh image and save the image so that I
        can just restore it. What's a good FREE *Windows* based software
        that can save and restore an entire disk image? Thanks.

5/27    I just spend a few hours on a silly BIOS problem and I'm posting it
        here so that you guys wouldn't have to go through this again. My
        MB is Gigabyte GA-7N400 Pro and the latest BIOS update is version
        F17, which is in 2004. It comes with the MB Sil (Silicon Image)
        3112A SATA controller, which unfortunately, is outdated from 2002
        and does not recognize my Seagate 750G drive-- the boot loader

5/17    My new 750G Seagate HD shows only 698G available. WHAT THE FUCK??
        \_ 750G = 750*10^9 bytes.  Your OS is probably measuring in 2^30 bytes.
           See GiB vs GB
        \_ Also, disk drive manufacturers advertise "raw" storage, while
           your O/S measures usable storage. You lose quite a bit to
           disk label information, metadata and other various things.

1/7     Looking to get an external HD for my mom (not yermom). Fry's has an
        ACOMDATA 250GB USB 2.0 for $70 after rebate, but I see only review on
        teh Intarweb (and it's suspiciously glowing). Any of you fine sodans
        have experience with this product or its ilk? TIA. --erikred
        \_ Seagate has 5 year warranty, I think. However their reliability
           has gone down the drain in the past few years. I have a WD250

        have the lockd problem that has been causing so much trouble. It has
        currently been up without a hitch for most of the night, and I hereby
        pronounce it more "stable." (Waits for the expected crash.) In any

9/11    For those who run his/her own server.  Has any of you tried to run a
        fanless system that uses AMD Operon or Pentium M that is clocked more
        than 1GHz?  where to get chassis like these?  can't find it at Fry's.
        \_ No, but I have a fanless 800 MHz Via C3, with a big Zalman heatsink.
           Got the CPU on ebay for about $50 and got the heatsink (CNPS-6000AlCu
           Flower Cooler) from http://endpcnoise.com for about $40.. Runs great.
