One year at Ahrefs: I started working at Ahrefs one year ago. When I applied I had heard of them from OCaml’s discuss amongst other OCaml community spaces and… https://tech.ahrefs.com/one-year-at-ahrefs-065167c61542?source=rss----303662d88bae--ocaml&utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet
Attempting overlayfs with macFuse: It would be great if overlayFS or unionFS worked on macOS! Initially, I attempted to use DYLD_INTERPOSE, but I wasn’t able to intercept enough system calls to get it to work. However, macFuse provides a way to implement our own userspace file systems. Patrick previously wrote obuilder-fs, which implemented a per-user filesystem redirection. It would be interesting to extend this concept to provide an overlayfs-style… https://www.tunbury.org/2025/10/06/overlayfs-macFuse/?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet

File descriptors as integers considered harmful: Continuing the previous foray into file descriptors, and trying to remove Obj.magic both from ocaml-uring’s code itself, and from the recommended way for using it. https://www.dra27.uk/blog/platform/2025/10/01/int-file-descriptors-considered-harmful.html?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet
File descriptors are not integers: There was a flurry of activity on ocaml-multicore/ocaml-uring this month leading to a release (ocaml/opam-repository#28604). ocaml-uring provides bindings to the Linux’s io_uring, which allows batching various syscalls to the kernel for it to execute out-of-order, and in parallel. Its principal use at the moment is for the high-performance Linux backend of Eio. https://www.dra27.uk/blog/platform/2025/09/30/file-descriptors-are-not-integers.html?utm_source=dlvr.it&utm_medium=mastodon #OCaml #OCamlPlanet
