7/4     Does anyone know how processor-intensive MP3 decoding generally is?
        My Celeron 300 is claiming to consume only 0.1% of the CPU according
        to top but my PentiumMMX 150 could barely keep up.
        \_ this doesn't answer the question, but I bet FPU, MMX, OS, and
           player all could have contributed to your results
           \_ pMMX150 256k L2 win95 winamp 3 >50% CPU vs.
              celeron300A 128K L2 linux 2.2.5 xmms 0.9 ~0.1% CPU
              I don't think this should account for a 500x speedup.
              \_ I do.  A guy I know swapped out a 200MhZ PPro for
                 a PII overdrive, his FFT benchmark got over a 200%
                 increase in speed. --jon
           \_ Celeron 450 (300) Win98 10-15% CPU
              \_ WTF?!? I get like 1%-3% on NT for OC 450
           \_ Amount of memory and types/sizes of caches can also be
              fairly vital.
        \_ Could be that the tools you're using to measure are wrong.

3/30    Does anyone have technical details of why BART's computer system is
        fucked up?  They installed a 'software upgrade'  what software?
        They 'switched to a backup system' but that failed.  Who is their
        primary IT consultant?
        \_ I bet BART is running a crazy ass minicomputer or mainframe
           from the early 80s.

2/10    What was your computer configuration during your UCB years?
        \_ None.
        \_ 286, 5.25" disk drives
        \_ 486-66, upgraded to 100MHz.  Worked far better than the HPUX
           machines compiling over NFS at the time (graduated in '97).

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.

6/2     I've been to many places and almost every place I go to have
        802.11b/g. However, almost all of them have protected access,
        which I presume they use because they don't want people stealing
        their bandwidth. So here is one idea I think will really
        revolutionize 802.11X... an option in the router that allows you to
        specify the percentage of unprotected bandwidth you are willing to

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%.

4/30    I'm thinking about getting my mom a mac mini. Right now I've got
        her hooked up on a Celeron in a small form factor, but I think
        Windows is too complicated for her. She's used to Macs from her
        Adult School, so I figure she'd be much more comfortable using
        it. The only thing is that I usually hack the firmware on these
        machines because she likes to watch foreign DVDs. Is it possible

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.

1/11    So the iMac Mini is basically an evolution of the old Cube thing. Or
        those little Shuttle PC boxes. Or a Gamecube. But it doesn't seem
        to make much sense compared to an iBook. Why no digital audio output?
        \_ you can still do digital audio over usb. Probably the reason
           there is no spdif connector is b/c of space/price. I think
           it makes a lot of sense (I bought one for my living room),

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.

        Celeron NT machine:

10/6    What's a good video card with DVI output to drive a LCD at
        1600x1200? Something not too expensive, under $100? I get
        confused looking at all the brands at newegg. Maybe something
        with Nvidia chipset? Thanks.

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
