Do Code That Matters

Deep-dive reference on hacking, modding, and community resources for the Sony A6000 (ILCE-6000) and A6400 (ILCE-6400) — OpenMemories-Tweak, PMCA-RE firmware dumping, clean HDMI/webcam hacks, IR & full-spectrum conversions, power/battery mods, S-Log video,…

How I run a coding LLM locally on a single RTX 3090 Ti — the model journey from Claude-distilled to a dense 27B coder, why MoE beat dense for speed, why I stayed on llama.cpp over vLLM on Ampere, and the quant type and sampler flag that quietly bit me.
