Lightweight runtime types for vanilla JavaScript

In plain words

Lightweight Runtime Types for Vanilla JavaScript is a utility library that enables type checking and validation directly in JavaScript without external dependencies. It's designed for developers who need runtime type safety while keeping their projects minimal and dependency-light. The tool allows developers to define and verify data types at runtime, making it useful for catching type-related bugs in vanilla JavaScript projects where TypeScript isn't an option or desired.

  Restate – Low-latency durable workflows for JavaScript/Java, in Rust2024 · restate.dev · ▲185

  We'd love to share our work with you: Restate, a system for workflows-as-code (durable execution). With SDKs in JS/Java/Kotlin and a lightweight runtime built in Rust/Tokio. https://github.com/restatedev/ https://restate.dev/ It is free and open, SDKs are MIT-licensed, runtime permissive BSL (basically just the minimal Amazon defense). We worked on that for a bit over a year. A few points I think are worth mentioning: - Restate's runtime is a single binary, self-contained, no dependencies aside from a durable disk. It contains basically a…

  Linux sysadmin course, eight years on▲780

  Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
