Where should the debugger set a breakpoint?
When you search for executions of a function in Pernosco (or set a breakpoint in a more traditional debugger), how does the debugger decide where to stop? You might think it just stops at the first instruction in a function, but that's not true in general. Debuggers actually stop immediately after the function's…

Detecting file changes on macOS with kqueue
A while ago I wrote a small file watcher in Go for my own use with an accompanying blog post . I needed a tool that I could just plop in front of the command I was running as part of my iteration loop. I use it for recompiling C files when I modify them,

Evolution of tree data structures for indexing
I have to admit, my research blog posts are getting longer and longer. From one side I find it genuinely encouraging, because if one gets so much information just by scratching the topic, imagine what’s hidden beneath the surface! One university professor once said “what could be interesting in databases?”, and it…

Homegrown Closures for Uxn
For a week or so now, I've been writing niënor , a "lispy environment for uxn" . I did not want it to become a full-blown lisp but just another way of writing uxntal . Uxntal is a bit too dense for my liking, and I prefer lisp/scheme s-expression syntax. Niënor is just a compiler and a macroexpander that takes in…
