A new project called Uberblok presents ZFS's internal mechanisms as a series of animated exhibits, each tied directly to specific lines in the OpenZFS zfs-2.4.4 codebase at commit 71a9f9578616. Every animation and code excerpt links back to the actual source, covering concepts like checksums, copy-on-write, and crash consistency that protect against disk failures and interrupted writes.
A developer built Qbix, a PHP webserver that forks thousands of lightweight worker processes from a single parent process using pcntl_fork(), relying on the Linux kernel's copy-on-write memory sharing. Unlike FrankenPHP, RoadRunner or PHP-FPM, which are limited by worker count due to memory duplication, Qbix lets each worker share the framework's loaded classes and only pay memory costs for pages it actually modifies during a request.
Developer ori has released a very early, buggy preview of GEFS—a crash-safe, snapshotting, copy-on-write filesystem originally built for Plan 9's 9front—running on OpenBSD. The port, under 9,000 lines of kernel code, is not intended for production use, with data loss expected especially during error conditions, and is not being proposed for inclusion in the OpenBSD tree yet.
