Unix tradition encourages the use of command-line switches to control programs, so that options can be specified from scripts. This is especially important for programs that function as pipes or filters. Three conventions for how to distinguish command-line options from ordinary arguments exist; the original Unix…

Programming is all about managing complexity. Without good tools to manage it, the complexity of programs becomes mentally intractable for our limited brains and we’d lose control and understanding of our programs (imagine writing a big software system entirely in assembly language).
This is the second part in a series on WebAssembly and what makes it fast. If you haven’t read the others, we recommend starting from the beginning. JavaScript started out ...

In my previous blog post on pointer provenance, I have shown that not thinking carefully about pointers can lead to a compiler that is internally inconsistent: programs that are intended to...

Two interesting things in formally verified software happened recently. The big one was the release of SeL4 - a formally verified L4 microkernel. The second was much smaller, but closer to my usual scope: a paper which showed the correctness of sections of a couple of the assembly implementations of Curve25519.

For 2003 OSCON I proposed to give nine five-minute talks in a 45-minute slot. To avoid confusing this with the real lightning talks sessions, Nat decided to call my talk ``Nine Views of Mark Jason Dominus''. At first I didn't like that title, which sounded too much like self-promotion. But I warmed up to it after a…
