Hacker News discussed `lsr`, an `ls` re-implementation using `io_uring` for potential performance gains. The chat explored `io_uring`'s benefits/drawbacks for CLI tools, its integration challenges, and `lsr` author's project goals. #io_uring 1/6
With the merge of https://github.com/varnishcache/varnish-cache/pull/4209 #VarnishCache is now prepared for using asynchronous I/O also on the network side.
Stay tuned.

🚀 New Blog Post: Kunai vs io_uring 🚀
💡 Ever wondered how io_uring revolutionizes I/O operations in the Linux kernel? Inspired by Armo's blog post (www.armosec.io/blog/io_uring-rootkit-by... about a PoC rootkit using io_uring, we explored this feature's security […]
Ersatz social image for the article; screenshot of title and abstract: " Let the kernel do the work! Tricks for implementing a pub/sub server This post explains the design of jetrelay, a pub/sub server compatible with Bluesky’s “jetstream” data feed. Using a few pertinent Linux kernel features, it avoids doing almost any work itself. As a result, it’s highly efficient: it can saturate a 10 Gbps network connection with just 8 CPU cores. May 2025 "
