Open source a evropská politika: nesmělá systematická cesta k otevřenosti

Root.cz - 3. Říjen 2019 - 23:00
[6 minut čtení] Většinou se o Evropské komisi píše v souvislostech s nějakými regulativy nebo pokutami, dotacemi nebo zasahováním do volného trhu. Dnes bychom se ale rádi podívali na to, jak Evropa pracuje s open source. Když se řekne open source a veřejná správa, většina z nás si vybaví především drobné případy, kdy nějaké město přejde z Windows na Linux nebo se otevřený kancelářský balík nasadí v nějaké oblasti ve školách. V posledních letech se ale téma otevřenosti stává součástí širší debaty o tom, jak by měla vypadat informační politika států (unie) ve vztahu k open source řešením, ať již v podobě softwaru nebo dat.

ASTC Texture Compression License Turns Out To Be Restrictive Outside Of Khronos APIs

Phoronix - 3. Říjen 2019 - 11:44
The lossy ASTC texture compression algorithm has been widely adopted in recent years with it being official extensions to both OpenGL and OpenGL ES. While it may not be as messy as the S3TC patent situation of the past, it turns out Arm's license on Adaptive Scalable Texture Compression actually is quite restrictive outside of the context of Khronos' APIs...

Igalia Is Working On "mediump" Support For Mesa To Help With OpenGL ES Performance

Phoronix - 3. Říjen 2019 - 8:47
Igalia is working on supporting OpenGL ES' GLSL marking of variables as "mediump" when the precision involving those variables can be lowered to half-float 16-bit registers. That in turn can help with performance when honoring that precision marking, which to date Mesa has ignored...
