I'm currently porting my software info-beamer (http://info-beamer.org) to the Raspberry PI and OpenGLES 2.0/OpenMax. Here is a small demonstration video: It's playing 2 videos and applying shader effects to them in realtime.

Hi. I started using Lua about 6 years ago. My first project (Infon Battle Arena) was a multiplayer realtime programming game. Players connect to a central server using telnet and upload lua code that controls their creatures. Players fight for resources. Programs can be updated anytime. There is a dedicated client which just displays the current game. The website is at http://infon.dividuum.de/. There is no real community, but the game is pretty stable. 

A more recent project using Lua is Geolua (http://geolua.com/). It's a platform to develop (multiplayer) games for mobile phones that run in a browser. The Lua code runs on the server and controls which widgets are displayed to the players. If you are interested, be sure to check out http://geolua.com/go/132. It's a demonstration for most of the widgets. Its sourcecode is linked in the description.

My latest project is info-beamer (http://info-beamer.org), an interactive rapid prototyping environment for visual presentations. For example "Information displays at conferences". Pieces of content (called nodes) are controlled by Lua. They can use Truetype fonts, videos, shaders or images to display information. The program is designed so content can be updated while running: If you change code and save the Lua file, info-beamer instantly reloads your code. Same with images and other resources. A (work in progress) visualization might look like this: preview: info-beamer @ 29c3 or info-beamer example visualization

Feel free to ask questions or give feedback. Thanks :-)

Stripe (http://stripe.com) hat aktuell eine CTF Challenge laufen. Ziel ist es, 6 unterschiedliche Sicherheitsluecken zu finden. Zugangsdaten fuer das erste Level gibt's auf https://stripe.com/blog/capture-the-flag.

Die 6 Luecken sind erfrischend unterschiedlich und es hat Spass gemacht mal wieder das Lowlevel-Stackoverflow Wissen anzuwenden (Damn you, Stack Randomization!).

Aktuell gibt es ein kurzes Adventure zu Stanislaw Lem als Google Doodle. Erinnert ein wenig an Samorost. Es scheint mir das aufwendigste der bisherigen Google Doodles zu sein. Und es hat ein spektakulaeres Ende. Also unbedingt durchspielen :-)

Edit: Debuginfos gibts mittels
http://www.google.de/?lem-debug&lem-show-performance

Per [Shift] kann das ganze im Debugmodus beschleunigt werden. [N] geht zu naechsten Scene, [T] sorgt dafuer, dass in der Canonenscene ein Treffer simuliert wird (bei mehr als 3 mal druecken gehts kaputt).

Source (nach beautifier sogar halbwegs lesbar):

(Unter lem.1.js gibts eine alte Version, in der wohl das Finale fehlt)
