12/2    my computer is probably 40 times more powerful than my
        first PC.  does my processor consume 40 times more than
        my first PC?
        \_ consume... power?
           \_ Vespene gas.
        \_ Quite possibly, considering that PCs in the old days didn't have
           CPU fans.
        \_ It definitely consumes more but not 40x.  Today's CPUs are more
           efficient in terms of speed to power usage ratio.
        \_ 486 was ~20W, original Pentium around 40. Max power per chip goes
           up about 4-5% per year currently (as per the SIA roadmap), much
           slower than the ~50%/year performance increase.
           \_ Hey, and the 90nm Athlon 64 3500+ uses 47.5 watts at 100% CPU!
              The 3000+ runs at 40 watts.
        \_ when viewing good soft porn DVD movies, yes.

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

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_?
        \_ Noone said VMs weren't needed.  They suggested you use the

12/3    Are any of you CSUA alums working at Intel?  Is it possible that we
        might be able to hit Intel up for donated/partially donated (reduced
        price) Core i7 Xeons when they come out?  Who would be a good person
        to contact about something like that?  We're of course willing to put
        out for them - perhaps we'll tattoo an Intel logo on toulouse if that's
        what they want :-p  -- steven

10/14   2 apache 2.0.52 servers running on Linux boxes.  Identical httpd.conf
        files (except for ServerName).  But on one, if a CGI script takes
        longer than 300 seconds, it times out.  The other, not.  Why is that?
        \_ Perhaps network equipment configuration. Or try comparing settings
           in /proc/sys/net.
           \_ I ran /sbin/sysctl -a | grep tcp, all settings are the same.

9/16    Tim Sweeney on the future of GPUs
        http://arstechnica.com/articles/paedia/gpu-sweeney-interview.ars
        I like Sweeney, I don't care about Unreal, but ZZT was a heck of a
        game
        \_ Interesting. Co-processor-like units have come and gone
           throughout the history of computing. GPU, co-processor, what-not,

           getting intel from them.

11/29   From the CSUA minutes:
        - Next Gen Console
        -- If we have $1800 in our accounts, should we buy a console:
           4 votes passes.
        -- Console voting: 2 votes each, neither passes
           * 360 = 600, more games

7/9     Are 64-bit Linux servers popular compared to 32-bit ones?  My company
        has a server product that supports 32-bit, and we're trying to see if
        it's worth supporting 64-bit as well.  Thanks.
        \_ in my company, everything linux is 64bit except the handful of
           redhat satellite servers, because redhat's sat server product
           doesn't support running on 64bit systems (yet).  DOH!
