What it does
Mnemosyne is a hermes-first, native, sub-millisecond memory system for AI agents using SQLite. No HTTP, no servers, no API keys. 500x faster than cloud alternatives. Open source.
Mnemosyne is a native, local-first memory system for AI agents using SQLite. No HTTP, no servers, no API keys. no network roundtrip, no cloud account. Open source.
The universal memory layer for any AI agent. SQLite-backed, local-first, one pure-Python dependency. One pip install. That is all. Independent, unpaid, and open source. These companies fund the compute and tooling that keeps the benchmarks honest and the CI green. Every partnership is disclosed and editorial control stays with the maintainers. Full-modal AI inference platform — one API for 300+ curated LLM, image, and video models, so you connect once instead of maintaining a vendor integration per modality. Powers Nightly recall benchmarks, multi-model parity tests, and OpenAI-compatible provider coverage in Hermes. 100% client-side simulation. Zero LLM calls. Zero server cost.

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
