A shallow survey of formal methods for C code
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.

Implementing a safe garbage collector in Rust
In my last post I introduced an Emacs Lisp VM I was writing in Rust. My stated goal at the time was to complete a garbage collector. I think Rust has some really interesting properties that will make building garbage collectors easier and safer. Many of the techniques used in my GC are not original and have been…

Is APL Dead? Not anymore
Is APL dead? Not anymore. Changes in modern hardware, business needs, development methods, and our understanding of programming makes APL in its modern state perhaps more relevant and viable than ever before.

Go and Simplicity Debt Redux
In my previous post I discussed my concerns the additional complexity adding generics or immutability would bring to a future Go 2.0. As it was an opinion piece, I tried to keep it around 500 words. This post is an exploration of the most important (and possibly overlooked) point of that post.

Rathbun's Operator
First, I’m a human typing this post. I’m not going to tell you who I am. Sure, many will say that is cowardly and fair, but I actually don’t think it would bring much value. What matters more is that I describe why, and what I did and didn’t do during the last two weeks or so with the OpenClaw agent I set up, known as…

From Rust to Ruby
Who does things like that?!? Apparently: me. I have my own project, written in Rust. Not a big one, mind you, maybe approx. 30k lines of code in total. Rust is verbose so it’s not really that impressive. I’ve put it aside for some time and was toying with local inference, LLMs, writing agents and my attention was…

Programming Bottom-Up (1993)
(This essay is from the introduction to On Lisp .) It's a long-standing principle of programming style that the functional elements of a program should not be too large. If some component of a program grows beyond the stage where it's readily comprehensible, it becomes a mass of complexity which conceals errors as…

Number in man page titles e.g. sleep(3)
If you do Linux systems programming, you will have likely pored over man pages, either on the command line or, my personal preference, using the excellent man7.org or linux.die.net. I’ve always seen …
