Getting 25 Gbps Thunderbolt Ethernet on My Mac Studio

I've been using the built-in 10 Gigabit Ethernet on my Mac Studio for a few years. It works fine: I can edit 4K video straight off my NAS over the network, and run backups at around 1 GB/sec. But... I want more. I upgraded my rack and my NAS to 25 GbE a couple years ago, and wanted to upgrade my main workstation, too.

Algorithms on billion-scale graph using 10GB RAM: I love DataFusion

In a previous post, I was sceptical about using Apache DataFusion for graph analytics. However, after some thought and experimentation, I changed my mind. I have reconsidered my approach and now have a working implementation of basic graph algorithms, such as WCC, PageRank and MSSP. For example, I can identify weakly connected components in a graph with two billion edges using just 10 GB of RAM and two cores. This is one of the most widely used graph algorithms and lies behind most entity resolution. The pure CSR of this graph requires over 15 GB of raw memory (or 30 GB if it is treated as undirected, as WCC requires). The hard limit was 10 GB of RAM when using systemd-run -p MemoryMax=10G, and the process was successful. Not Vibe-coded.

A GTK4 SSH-askpass in Zig

Every ssh-askpass in the Gentoo tree pulls in X11 or a full KDE stack, so I wrote my own with Zig 0.16 and GTK4, with hand-written bindings that keep X out of the build.
