Project mention: Solidjs: Simple and performant reactivity for building user interfaces | news.ycombinator.com | 2025-04-19
Looks like its still in the discussion phase, did not see a timeline but also did not read super close. Did learn about the tanstack-router which I had never heard of, so that was worth looking this up right there ;)

Project mention: Top 7 Puppeteer Alternatives for Web Automation and Testing (2025) | dev.to | 2025-08-05
WebDriverIO is a highly customizable and extensible Node.js testing tool built on the WebDriver protocol. It enables developers to perform both headless browser scripting and full UI testing across major browsers and devices. Its clean syntax, plugin system, and CI-friendly design make it a practical Puppeteer substitute for large-scale test suites. Unlike Puppeteer, which is Chromium-centric, WebDriverIO offers robust multi-browser automation using both WebDriver and DevTools protocols. It supports Chrome, Firefox, Safari, and even mobile testing through integrations like Appium.

> Unlike Node.js, Rust's Tokio allows us to spawn a new Task and run futures within it.
Nice article! For future reference in Node.js this would be `worker_threads` or if you want a higher level tokio like API something like https://piscinajs.dev/
This has been possible in Node.js for quite a while

Project mention: CI/CD Observability with OpenTelemetry Step by Step Guide | news.ycombinator.com | 2025-06-15A child comment mentioned k8s but I also have been chomping at the bit to try out the eBPF hooks in https://github.com/pixie-io/pixie (or even https://github.com/coroot/coroot or https://github.com/parca-dev/parca ) all of which are Apache 2 licensed
The demo for https://github.com/draios/sysdig was also just amazing, but I don't have any idea what the storage requirements would be for leaving it running
