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…

Compile time evaluation in Nim, Zig, Rust and C++
Evaluating code at compile time is a capability that most, if not all, compiled programming languages possess, even if it can't be directly used by the programmer, but rather applied as an optimization. In this post, we'll explore a bit how to execute code at compile time in Nim, Zig, Rust and C++.

Is XMPP any good? Also, let's write a client in Tcl, maybe
I still have my Nokia 5800 lying around. It runs Symbian. That platform is quite different from Android. For one thing the internal storage size is 81 MB - less than what your single android app takes up, even in RAM, and it works faster than modern smartphones - e.g. the SMS app opens instantaneously. Another…
