Slides and example programs (source & video capture), from my fosscomm2013 talk on multithreaded and GPU programming: t.co/RDqR7Mn40Y
-
This Sunday Ill give a talk at http://hua.fosscomm.gr on exploiting the comp.power of parallel architectures:from threading to GPU computing
-
I'm a control freak with code and hate using black boxes,but sometimes it's fun to just throw in a single OpenMP line and see it go 4xfaster
-
finally .... winter is coming! (it is known)
-
How the hell is it possible to find a bug today in my quaternion interpolation code,which I've been using since 2003 in countless projects?!
-
Ok I give up. is there ANY usable mail client on android? Is threading so fucking much to ask of a MUA in 2013? Also wrapping at 72columns?

The Journal of Computer Graphics Tools, the first open-access journal for comp. graphics, released its first completed issue http://jcgt.org

Completely addicted to FTL! can't stop playing... great game, but I *must* abstain to get some work done soon :) [ http://www.ftlgame.com ]

aparently the android ndk build system compiles with -msoft-float! I suppose it helps portability,but it's high time I write my own makefile
-
Finally tried out OpenGL tessellation shaders. Did a GPU bezier eval, and a crude performance comparison with CPU ver.: http://t.co/tJ0d1Oye
-
Just ordered a new graphics card. Can't wait to try out the new OpenGL tesselation shaders :)

Just posted on my blog about generating multiple sample subpixel positions, for antialiasing in ray tracers: http://t.co/NhHionsz

Just posted on my blog about correct OpenGL rendering in a linear color-space, and gamma correction: http://t.co/h9W2JR9K

Just posted on my blog about an extremely simple, but effective way, to add color-grading in a game: http://t.co/kWnLFsEZ

Just posted on my blog about a first person dungeon crawler game I'm writting. Includes video capture of a prototype: http://t.co/ENUX13uP

One moment of silence for the most awesome monitor I ever owned: my trusty samsung 959NF 19" CRT. I used it for about 12 years. Now retired.

Programming is all about understanding your program, not about giving up the controls and hoping for the best...

Smart pointers are BAD. If you don't know which part of your code is responsible for what, no amount of ref. counting and RAII will help you

Git sucks ass, get a grip people. Also github is for trendy social web3.0 hipster-programmers. Try mercurial for a really nice DVCS instead.
