   A hash array-mapped trie implementation in C▲171

   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…

    A Swiss army knife for testing HTTP from the terminal▲110

    Hiya HN! Just released Artillery Probe - a Swiss army knife for testing HTTP from the CLI. Think mini-curl with better UX for common use-cases, plus a couple of extra features. Would love for you to try it and give some feedback! https://www.artillery.io/blog/swiss-army-knife-for-http-testing and: npm install artillery@latest What does it do? - First of all, it's a HTTP client! It does all the usual stuff you'd expect from a HTTP client... HTTP methods, request bodies, custom headers, forms, Basic Auth etc. - Got some JSON or XML back? It'll pretty-print it, and syntax…
