I use wmaker at work and have my home desktop set up with the gnome panel on

gtk+ 1.4 is supposed to incorperate some changes that will make pixmap themes a
lot faster, I haven't been watching those mailing lists too closely lately
(little interesting stuff, this list is much more fun :)

ahhh, different game :) q3 barely sludges along on this thing, I was playing it
on a p166/48m with a v2 and at a noticable disadvantage to my coworders (all
v3's on 400's with 128m ram)... i was only leading them by a little bit :) One
thing I'd like to say is that my coworkers became very envious of my stability.
They would crash many times a night and I would have no reboots or anything, I
just kept going. My boss was asking a lot of questions about office
productivity stuff, so I got to show him stuff like star office. Unfortunantly
he chickened out, but I may still turn him :)

I read a couple reviews and comparisons in gaming magazines, and they seem to
indicate that g400's are "ok" speedwise, but offer better visual quality. These
were before geforce256, so I d'no how that compares :) I've talked to people
who have g400's and they say that they run really well on linux. If matrox
would give the "utah" drive ppl the rest of the information, I think that the
millenium cards will be pretty hot under linux :) I still have time to consider
the options, and I will definitly do more research.

Yeah, I see. I guess I feel that bmp was a bad choice :) I see "wav" and "bmp"
in the documentation and I think it's a windows wannabe type thing *shrug* but
everything else indicates a high quality peice of work :/ I guess I'm biased :)

you betcha :) I remember uncontrollable wobbling and 800 lines of code a
night... (I think 800 is fairly decent for one sitting)

I saw corel :) with it's "insert the cd in windows and click this" install and
everything... :) I used to use redhat, and I personally feel 4.x was their high
point. I got frustrated with their scripts and how flaky rpm was so I switched
to debian. I got into linux in '96 and I always remember it being rc?.d and

debians got ip-up and ip-down.... I d'no, I never use 'em anyways. I like to
scrap together my own scripts, it's a nominal amount of effort :)

Anything that has "MICROSOFT" stamped on it will get used. It's an unfortunant
reality. I've been working a lot with databases lately (mysql and postgresql),
and have had the misfortune of being exposed to access. But access seems fairly
common in smaller business environments (cheaper than oracle, but still a "name
brand"). DX is being used, but I'd imagine most developers aren't happy about
it. I have a suspicion that the programming groups that work as independant
teams use dx as little as possable (sound and interface), while the corporate
drone groups with pointy haired bosses use dx is all it's "glory"... I think
the things we can learn from dx are to use it as an example of what not to

these're things I guess I should learn :)

this was a "hax0r" wannabe who didn't want to be seen spying :/ (renaming
ttysnoop and ttysnoops would have sufficed...)

hehehe, I plugged in esd support into my game engine for q&d sound, it's
extremely easy to use and seems to be pretty good in terms of memory and speed.
However, there is some sound degradation going on. I have an mp3 player that
can output over oss or esd, but I use oss because it sounds cleaner and retains
the lows... Why I'm saying this, I have no idea. for putting sound into
something quick, esd is very good. And since gnome uses it, gnome desktops get
the benefit of real mixing, which is something I personally think should be
kernel level.. (does also do mixing? someone mentioned alsa and the kernel)

I don't think you should learn assembly to use it occasionally... I really
doubt there's a serious need. I think asm is important to learn so you
understand why x++ is better than x=x+1 (unless the compiler optimizes that for
you...). And stuff like loops... having an idea of how that gets handled by the
machine lets you make your programs more friendly to the machine. (but we still
need skilled asm hackers to glue together the compilers so they use mmx and
3dnow and superdoopermegahyperglobalultra4324252 instructions... :)
