Ratchet – safe SPI flash writes (polling, erase-verify) in Rust

What it does

A hardware debug and flash-programming toolkit for CH341A and CH347 USB programmers. Its core is SPI flash programming and BIOS analysis, the path that drives live silicon end to end. Around it sits a unit-tested protocol layer (I2C, UART, 1-Wire, passive SPI sniff, JTAG, SWD, CAN), target-MCU programmers (AVR ISP, STK500 / Arduino bootloader, 24Cxx and 93xxx EEPROM, ESP32 / ESP8266, STM32 over SWD and AN3155 UART), an ARM debug surface (ADIv5, Cortex-M halt/resume/step, ELF-aware memory peek), JTAG IDCODE and BSDL boundary scan, a logic-analyzer model with Saleae / sigrok export, and Bus Pirate / slcan CANfrom github.com

  LocalGPT – A local-first AI assistant in Rust with persistent memoryFeb 2026 · github.com · ▲331

  I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system). It compiles to a single ~27MB binary — no Node.js, Docker, or Python required. Key features: - Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider:…

  Unbug – Rust macros for programmatically invoking breakpoints2024 · github.com · ▲96

  This project is inspired by some of the asserts in Unreal engine. Due to reliance on core_intrinsics it is necessary to develop using nightly Rust, but there are stubs in place so a production build will not require nightly. I recently released version 0.2 which includes no_std support and adds optional log message arguments to the ensure macro.

  Nanosecond C message logger2019 · ▲131

  Hello, Some time ago I did a data logger for fun, just to check if I could beat the performance of an old C++ project of mine (mini-async-log) and to avoid letting my multithreading-C skills rust when on a non-programming gig (using Yocto/OE, very little programming). This project is a BSD licensed, producer-wait-free (when using thread-local storage) generic message logger with high performance, decent test coverage, and type-safe C strings (requires C11 or C++ compiler). It was a shame to let this project to die unknown, as I think that it has potential to be used on some niches as…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, 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!
