CodeSpeak is a new programming/specification language from the creator of Kotlin designed as a formal way to communicate with LLMs, letting developers write specs that LLMs generate into working code. It claims to shrink codebases 5–10x for production-grade systems, supports mixed manual/generated projects, and presents case studies showing large LOC reductions while preserving tests.

The author created a glitched, colorized version of the 1922 film Häxan by directly editing the h264 bitstream (hex). After two unsuccessful approaches (NULL-ing frames and injecting raw YUV noise), they settled on randomly flipping least-significant bits in I-frames biased toward chroma data, and provide a Python script (häx.py) plus ffmpeg commands to extract, glitch, and remux the video.
