    Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate. Such a nice DX combo for writing new languages. Still a work in progress, but I thought I'd share :)

    Manipulating monetary amounts is a common computing chore. However, no mainstream language has a first-class data type for representing money, it’s up to programmers to code abstractions for it. This isn’t an issue per se until dealing with rounding issues from operations like installment payments (e.g., buy now, pay later), foreign exchange, or even simple things like fee processing and tax collection. Inspired by my days at N26 Brasil dealing with these challenges, I introduce Money: a Kotlin library that makes monetary calculations and allocations easy.

    Since there is so much interest on HN in floats lately and their software implementations, I wanted to show mine. It has no use and is just for teaching me floats and C++. Give me your thoughts.

    We're building a different kind of JavaScript engine, based on data-oriented design and willingness to try something quite out of left field. This is most concretely visible in our major architectural choices: 1. All data allocated on the JavaScript heap is placed into a type-specific vector. Numbers go into the numbers vector, strings into the strings vector, and so on. 2. All heap references are type-discriminated indexes: A heap number is identified by its discriminant value and the index to which it points to in the numbers vector. 3. Objects are also split up into object kind -specific…

    Hey HN! We're so excited to show you Val Town (https://val.town)! A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule it - all from the browser, in a couple keystrokes. We're a startup of 4 people, mostly in NYC. We've been working on this for 6 months and are eager for feedback from the HN community. Why do we need yet another online coding IDE? While researching devtools[1], I found myself wanting something halfway between Replit and Zapier: a…

    Hey HN! I built Typebase, a library that gives you Convex's DX with Supabase's openness. After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults. With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in. Then one…

    Hey all, I just released v2.0.0 of FilterQL, a query language and TypeScript library. This version adds support for Operations, which allow you to transform the data after filtering. If you think this would be useful in a project you're working on, give it a try and let me know what you think!

    This is a Python package that allows you to write function signatures to define LLM queries. This makes it easy to mix regular code with calls to LLMs, which enables you to use the LLM for its creativity and reasoning while also enforcing structure/logic as necessary. LLM output is parsed for you according to the return type annotation of the function, including complex return types such as streaming an array of structured objects. I built this to show that we can think about using LLMs more fluidly than just chains and chats, i.e. more interchangeably with regular code, and to make it…
