After two weeks of wrangling, finally got the next batch of AV1 packages built for Arch into the repo. Should be back on the regular schedule of weekly releases unless something else rears its ugly head.
- Some packages require GCC 15 and absolutely hate GCC 16
- Zig 0.16 is not an option for a lot of stuff
- VapourSynth API v3 C headers are no longer included with the Arch Linux package, so had to grab those from the repo and get them to the right spot
Quantizing Tangent Frames
이 글은 3D 그래픽스에서 정점의 접선 공간(tangent frames)을 효율적으로 양자화하는 다양한 기법을 비교 분석한다. 저자는 정규 직교 접선 공간을 전제로, 8바이트 기준 SNORM10x6, 4바이트 기준 옥타헤드럴 인코딩, 쿼터니언 인코딩 등 여러 방법의 각도 오차를 측정했다. 특히 쿼터니언 인코딩에서 10비트 3축+2비트 축 인덱스 방식이 4바이트 내에서 비교적 낮은 오차를 보이며 실용적임을 제시한다. 이 연구는 GPU에서 접선 공간을 저장할 때 메모리 절약과 품질 간 균형을 고민하는 그래픽스 및 AI 에이전트 개발자에게 유용하다.
I’ve been working on tangent space generation recently, and also pondering the tradeoffs between QTangent and normal-angle storage. So when, in a completely unrelated discussion, someone said “you could store tangent and normal as two RGB10A2 attributes”, I decided I should measure this once and for all and write it up.
Danke an das City Carr� Magdeburg f�r diese Anzeigetafel mit ausf�hrlichen und au�erordentlich n�tzlichen Informationen zum �PNV.
(ich bezweifle allerdings wirklich, dass in Magdeburg morgens vom Hauptbahnhof und vom ZOB eine Stunde lang keine Busse und Bahnen abfahren …)

Well, Qwen 3.6 35B A3B UD K_4_XL quantized model cannot reliably follow web standards too.
What does it mean concretely?
- It seems to produce structured C++ like a libcURL god: code compiles.✅
- The program runs until it reaches an external UTF-8 compliant API.❌
⚠️ Scrap The RFC -> "rfc8259: JSON text exchanged between systems that are not part of a closed ecosystem MUST be encoded using UTF-8 [RFC3629]".
-> It broke my vibe (sarcasm intended). -> fAIl. #vibecoding #encoding #JSON
Hey @gianni I was just chatting with @yawnbox about a wild range of tech things, and, since I am starting to host an Immich instance in my home, I am considering to convert all my emails to JPEG XL, and I was wondering if there is a way to do so without risking to lose any metadata.
I am happy to read any links you might have but I need them to be as simple as possible because encoding/decoding stuff confuses me a lot. Not my thing… This is why I found your article explaining how AV1 works in simple words absolutely illuminating! Anyway, I just want to save storage space.
Also, I am a big big fan of Aviator, and I have been following your work for a while. Thanks so much for all of it!

@Lana if musical notes are representations of numbers or letters, is it a hidden message of some kind?
