Person Milestones

Zeda joined the TI comunity in 2008 under the name "Sven Thomas." She became an active member of the community in 2010 and has since remained so. Her first major contribution to the TI community was her use and knowledge of hexadecimal programming. She brought many codes to BASIC programmers that could not use connectivity software. She also debuted some of her first assembly libraries at this time. She then began work on BatLib which is an app and assembly library like xLIB or Celtic 3. It currently is the most command packed library with over 100 functions and a programming language in a 1-page app. Her next major contribution to the community was the Grammer programming language which is a very fast alternative to BASIC.
