Show HN: Nos – a hobby x86-64 C++ OS kernel running on real KVM clouds

https://github.com/irqlevel/nos

Hi HN,I want to share nos, a hobby x86-64 OS kernel I’ve been working on.I started this mainly because I wanted to learn kernel development properly, and studying the Linux kernel feels pretty overwhelming these days. It’s huge, highly optimized, and hard to follow end-to-end. So I decided to build something smaller but still realistic.nos is written in C++20 + NASM and currently has:SMP +...

Re:WhisperClip: 300ms Voice-to-Text on macOS (Fully Local) on Wednesday January 14, 2026 @02:30PM (#46621497)
Parakeet engine with Apple Neural Engine enables fast and accurate transcription: ~300 ms per sentence, ~700 ms per paragraph, and around 20 seconds for 1 hour of audio.

Transcribe audio files in MP3, WAV, M4A, FLAC, and OGG formats via drag and drop.

Full transcription history with searchable text.

Recording overlay, start-minimized option, and hold-to-talk mode.

Show HN: Real-time, open-source voice assistant in Rust

https://github.com/cydanix/voice-agent

Work in progress. User pause detection may not working properly and llm/tts interruptions is not implemented yet. It's already can run and answer questions, but you need headphones to avoid echo problem (use laptop mic as input and headphones for output). Sorry, I'm not Rust pro, so the code maybe ugly, most of the code vibe-coded.

Everything runs fully offline — no cloud, no tracking.The app is currently in beta and supports PDF files only. The only time an internet connection is needed is during the initial LLM model download at setup.Any feedback is very much...

This issue has been reproduced and fixed in version 1.0.44, now available on the website. Note that when you update the app, the models will be recompiled, so the app may briefly hang during recording. Each new app version → new hash → AI (MLX) code recompilation.

Thank you for the feedback. I will improve the onboarding and setup in the next app release.

Sorry about that — this feature is no longer available due to its cloud-based nature, but I plan to bring it back. The video was recorded before open-sourcing, so I’ll remove it to avoid confusion.

Update: Replaced the site video with a demo showing the actual app behavior.

Thank you for the feedback. I’ll work on reproducing the issue and will do my best to fix it.

Thank you — any feedback is appreciated. I want to be useful, not rich, so I made it open and free for everyone
Try https://whisperclip.com —it delivers low-latency, real-time voice-to-text streaming to any macOS app.
No, I use an in-house model based on some open analogs.

No, they already have, but their mechanism have a lot of limitations because it's not a primary business for them. More details you may read in our blog article - https://cydanix.com/blog/Evaluating-the-Limitations-of-Nativ... .

No, but may be in future
