Project mention: Node.js Event Loop: The Key to Scalable and Efficient Applications | dev.to | 2025-03-11
The event loop is the core mechanism in Node.js that enables non-blocking I/O operations. Despite Node.js being single-threaded by default, the event loop allows it to perform asynchronous operations by offloading tasks to the system kernel or Libuv's thread pool. This makes Node.js highly efficient for I/O-heavy applications, such as web servers and APIs.

Project mention: Show HN: Crawl a modern website to a zip, serve the website from the zip | news.ycombinator.com | 2024-06-10
The libwebsockets server (https://libwebsockets.org) supports serving directly from zip archives. Furthermore, if a URL is mapped to a compressed archive member, and assuming the browser can accept gzip-compressed files (as most can), then the compressed data is copied from archive over http to the browser, without de-compressing or conversion by the server. The server does a little bit of header fiddling but otherwise sends the raw bytes to the browser, which automatically decompresses it.

This is incredibly funny to me, because this is almost exactly how some of our other tests work :D
(Almost: we have a full-featured command shell and just use that for testing)
