so, it only took an afternoon for it to dawn on me that i should install a new kernel to get the 1394 stuff to work. sure enough, it behaved much nicer afterwards.

camera seems to be doing well, execept the lens has some serious radial distortions going on. ended up spending friday trying to compensate for them. it's not quite there yet; i'm still using a fixed center and was too lazy to write the 5 lines to do interpolation, but it is looking better.

i need a wort chiller. though, waiting for it to cool does give me a good excuse to do laundry and catch up on diary entries

tomarrow is the day of seminars.. all morning long. eug.

probably will try and get a 1394 board up in the afternoon, so i'll have a camera to start playing with projector alignment. pretty neat idea. if you can determine how your projector is aligned with respect to its display (given a sane display surface..) you can invert the transform, plop it on your matrix stack, and poof. a corrected display.

whats that?

added some cheesie fonts and tooltips to my graph editor.. its almost time to make it do something useful.

wow. slacker i have been, mmh? no diary entry in six months.. geez

school

does it really count as school if you are not taking any classes? have been trying to get our display wall up and going at a reasonable rate, which involves playing around with xfree86 and the dri to convince the mga driver to blit once again. still have some funkiness to straighten out, maybe by the end of the week.

can't seem to reach any machine on campus atm.. but, its sunday morning, and they have been known to throw in unscheduled power outages then. still, thank goodness for UPSs and ext3.

summer fun

a good friend of mine just happened to schedule her wedding the same week as siggraph.. doh! at least MN will be somewhat cooler than TX in late july..

fun

finally getting around to working on a little graph editor to use for a front end for some 2d stuff. nothing fancy, but i'm sick of writing a new interface every time i want to play with someones paper and want something i can reuse.

well.. i managed to aquire a new power supply.. woohoo.

sadly, the machine refuses to do anything. no post beep, no beep error when i pull out dimms. i fear the mobo may have fallen victum to the the power spike.

tho id like to stick my procs in someone elses box to make sure that they are still alive... bloody oath..

spent the morning talking to myself.. fixed the audio underruns, but killed the sync.. oh well, it seems to be working now. the next challange, can we find enough bandwidth to pipe the stream out to new mexico.. hmm.. probably not..

wouldnt it be great if there was a diary digest mode? ie one big honkin page that listed all the new diary entries in the past day.. cause im lazy and dislike having to click on 15 links to read everything thats going on..

swiped a new chair out of the surplus pile today.. well, its not new, but its well broken in.. chairs are only good once the springs that keep them from reclining are completly shot, and you have to always sit at a pi/4 angle.. mmm.. though the arm rests are a bit torn up.. my office mate suggests electrical tape; i suggested a cup holder.

someday i'll get around to getting a new PS.. but its all rainy today, and i left my wallet in another pair of pants, so no lunch for me.. sigh..

so, the power supply on one of my machines went ka-boom over the weekend, just as we were settling in for many hours of counter strike.. pretty violent, c omplete with booms, crackles, high pitched whines, and plenty of stinky smoke.

it was not even a year old.. <sniff>. would an open casket be inapproprate?

though, dv streaming now works fairly well.. still have a few audio underruns, most likely because im lazy and dont want to write multi-buffers..

woohoo.. so i now have an advagato account, which i consistantly want to misspell as 'avagadro'... theres just too many vowels...

anyhow, its rainy and generally poopy outside today. so im inside hacking, as tuhina is out of town, and, well, what else is there to do in this town..

the mission for today is to beat dvts into using libdv, so hopefully it will be a bit faster. then, slap a dv board into HrchekKalFas (our new office machine, named to discourage remote logins... hint: its a star wars character), and they can spy on us from upstairs over the fiber that they have supposidly installed (at least they were poking around in the cieling yestorday, looking very lost)

when i get fed up with that, which probably will be any minute now, i'll head home and start hacking up new, cleaner sequence handling code for mflip
