Linux Kernel Module & Userspace app in Rust

• https://github.com/pettijohn/corsair-ai-workstation-performance-level-linux
• Reverse engineered a Windows-only driver for a desktop PC’s performance level button to replicate on Ubuntu 26.04 with 7.0 kernel.
• 100% Rust. Extremely efficient.

Whisrs Voice Dictation

• https://github.com/y0sif/whisrs/pull/50
• Whisrs is a Linux-native voice dictation software in Rust with support for multiple speech recognition providers including cloud and local.
• Pull request added support for realtime dictation for OpenAI-compatible endpoints, namely Lemonade.
• Before this PR, the app supported realtime for OpenAI cloud dictation, or batch transcription (process the whole recording when when recording stops) for OpenAI-compatible, or realtime with Whisrs-hosted whisper.cpp (CPU-only).
• Pull request refactored OpenAI realtime transcription to a shared component that OpenAI-native and OpenAI-compatible can use.
• Added over 100 unit tests.
• End result: realtime, fully-local, fully-private, GPU-supported voice transcription for Linux in Rust.
