Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

I'm excited to share Hashmap.me, a small tool I've built to simplify data storage and retrieval. It's a straightforward service that allows developers to store data records via HTTP requests and retrieve them easily, all without the hassle of setting up and managing a database. Initially I built this because I was tired of creating a database to prototype my own projects, I just wanted to persist my in memory cache between restarts early on. Each hashmap you create corresponds to its own collection in MongoDB. Perfect for small projects, quick prototypes, or learning purposes. I'd love to…

Morning HN. Random number generation feels is a somewhat underrepresented topic in the C++ realm. There is a lot of questionable info about it found online and even the standard library is quite behind the times in terms of it's algorithms. It suffers from trying to accommodate sometimes impractical standard requirements and has several ways of getting significantly bad statistical results. This leaves a lot easily achievable performance & quality on the table. So, being a mathematician who mostly works with stochastic models and wants these models to run fast and well, I embarked on a…

I kept rewriting the same array.slice(i, i + n) logic in every project. Eventually, I decided to stop and just make a utility. Chonkify is a small (~870B), zero-dependency JS/TS library for chunking any kind of data: - Works with Array, String, Buffer, Set, Map, Array-like, TypedArray - Handles AsyncIterable (great for batching streams) - Unicode-safe (correctly handles grapheme clusters, emoji, etc.) - ESM-first, TypeScript-ready I mostly made it for myself, but figured others might find it useful too. Would love feedback!
