Linear Algebra of Types (2019)
It gives my brain a pleasant thrum to learn new mathematics which mimics the algebra I learned in middle school. Basically this means that the new system has operations with properties that match those of regular numbers as much as possible.

Refix: Fast, Debuggable, Reproducible Builds
What makes it really fast is a small Rust program called refix that post-processes your build outputs (if you don't want to compile from source, here's a static Linux binary .) Both the program and this document are written for the context of C/C++ source code compiled to native binaries. But this can work with other…

Ethereum has blobs. Where do we go from here?
On March 13, the Dencun hard fork activated, enabling one of the long-awaited features of Ethereum: proto-danksharding (aka EIP-4844 , aka blobs). Initially, the fork reduced the transaction fees of rollups by a factor of over 100, as blobs were nearly free. In the last day, we finally saw blobs spike up in volume and…

Infinite Mac: Turning to the dark side
tl;dr: No, not Windows¹, but I’ve decided to expand Infinite Mac to the the black hardware that Mac users secretly lusted after in the 80s and 90s: NeXT. There is now a runnable collection of all notable NeXTStep versions , going from the initial 0.8 preview in 1988 to the final OPENSTEP 4.2 release in 1997.
