Show HN: ContextVault – Shared memory layer for your AI and your team https://ift.tt/qvjfMiy
Show HN: ContextVault – Shared memory layer for your AI and your team Hi HN, I'm Kevin. I built ContextVault because I kept running into the same problem with AI tools. Every project accumulated prompts, coding conventions, architectural decisions, examples, and other pieces of context that made the models significantly more useful. The problem was that this information quickly became fragmented. Some lived in ChatGPT Projects, some in Claude, some in Markdown files, some in internal documentation, and some only existed in previous convers…

Show HN: Openleetcode – LeetCode runner where tests live in the repo https://ift.tt/G4dAv7K
Show HN: Openleetcode – LeetCode runner where tests live in the repo You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 800 problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. https://i…
Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go https://ift.tt/0W28gcj
Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go Rate limiters and circuit breakers work wonderfully well when they’re configured for the load and available capacity. But load, capacity, and latency drift over time, and keeping those settings current requires continuous effort. So I built Levee to be a hands-off, adaptive, easy to configure traffic governor. Levee is configured with a success-rate target and timeout. It then continuously monitors the workload performance characteristics to detect downstream capacit…
Show HN: The Quiet Map – Earth's quietest place, measured by seismometers https://ift.tt/GLHJDvi
Show HN: The Quiet Map – Earth's quietest place, measured by seismometers Hey HN, This started as a personal curiosity and Claude helped me build it out. The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now. Hope you enjoy it and wo…
