La fotografia Schlieren és una tècnica que permet captar el so o la calor.
Es capten les variacions en la densitat d'un fluid (l'aire en aquest cas) generades pel so o la calor. Aquestes variacions es coneixen com l'efecte Schlieren, i van ser descobertes pel físic alemany August Toepler al 1864.
Valve Open-Sources Their Direct3D To OpenGL Translation Layer
With Valve's Source Engine originally just targeting Direct3D, when initially porting their games to Linux and OS X they relied upon a hand-made Direct3D to OpenGL translation layer. In potentially assisting other game developers, Valve Software has now opened up this graphics translation layer.

El còdec H.264 de Cisco serà gratuït, el vídeo a la web és el gran beneficiat
Els avantatges tècniques del còdec H.264 eren un punt molt a favor davant alternatives Open Source com VP8, utilitzat en el contenidor WebM impulsat per Google. Ara Cisco ha anunciat en un acord conjunt amb Mozilla que farà que el seu còdec H.264 sigui Open Source gratuït (de codi font res, com hem pogut saber). Això permetrà que Mozilla l'integri en futures versions del Firefox. Cisco proporcionarà a més mòduls binaris gratuïts.
FLOSS Manuals is more than a collection of manuals about free and open source software, it is also the community. The writers include professional authors, editors, artists, software developers, activists, and many others. Anyone can contribute to a manual – to fix a spelling mistake, add a more detailed explanation, write a new chapter, or start a whole new manual on a topic.
Launched in 2007 to remedy the deficit of good free documentation about Free Software, the Floss Manuals' strategy since the beginning has been to develop communities to produce high quality free manuals in their own language. Today we have more than 120 books in more than 30 languages.

A modular synthesizer is a type of analogue computer which is programmed by connecting the inputs and outputs of various functional modules to each other, typically in order to produce or process audio signals. The advantages of a modular synthesizer are its expandability and flexibility, since a system can be designed around goals the user wishes to achieve, and easily reconfigured (or patched) for multiple uses. Video synthesis is another application of the modular synthesizer, and while the application is different, the same principles of analogue signal paths and voltage-controlled parameters still apply.
While many functional modules are useful for both audio and video, some new module designs must be introduced which deal with the special requirements of video signals. The LZX Visionary modular video synthesizer can function as a traditional video mixer, keyer, or special effects unit, or delve into experimental territory such as the creation of abstract patterns with voltage-controlled oscillators, complex color space modulation, audiovisualization, and many as yet to be discovered techniques.
Their current line of Eurorack video synth modules includes:
