c'est moi

CV

I'm a professional programmer/musician. I'm mostly here for the code and somewhat for the insanity :) I'm literate in most major languages with a bias to C++, Python, Smalltalk and Lisp and I'm a *nix head from way back; yeah BL (Before Linux). Don't ask me anything about Windoze.

SL

I run a scripting/gadget biz in SL under the handle Kwerks but mainly do custom work. Feel free to give me a buzz if you have something on your mind. The lab is in Alleni/66/190/31.

JIRA

Some viewer patches I have thrown at the JIRA

Load/save script files to the editor from local disk: https://jira.secondlife.com/browse/VWR-5206
Autosave scripts in case of crash: https://jira.secondlife.com/browse/VWR-5215
Line number gutter for script editor: https://jira.secondlife.com/browse/VWR-5283
Toggle comment selection, shift selection left/right for script editor: https://jira.secondlife.com/browse/VWR-5304
Preference panel for the script editor: https://jira.secondlife.com/browse/VWR-5318

LSL

Texture Cycle: http://wiki.secondlife.com/wiki/Texture_Cycle

Color Cycle: http://wiki.secondlife.com/wiki/Color_Cycle
PHP5 class for the XTEA impl: http://wiki.secondlife.com/wiki/XTEA_Strong_Encryption_Implementation#XTEA_LSL_.3C-.3E_PHP

Offline LSL Syntax Checker

I use this to do a quick syntax check on LSL files from my normal editor. It requires that you have the viewer source installed and built on your machine. I built this on OS/X so Linux will probably be fine and I have no clue how to make it go on windows.
