Weird Expressions in Rust
Rust has a very powerful type system, but as a result it has some quirks, some would say cursed expressions. There’s a test file, weird-expr.rs , in the rust repository that tests for some of these and makes sure there consistent between updates. So I wanted to go over each of these and explain how it’s valid rust.

Parameterized types in C using the new tag compatibility rule
C23 has a new rule for struct, union, and enum compatibility finally appearing in compilers starting with GCC 15, released this past April, and Clang later this year. The same struct defined in different translation units (TU) has always been compatible — essential to how they work. Until this rule change, each such…

I Switched from Flutter and Rust to Rust and Egui
This is just a personal experience, there are no absolute truths. Like in any other blog post, a lot of the things you'll read here could be just a skill issue, or legitimate issues. It's up to you to decide.

Making TRAMP faster
I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines. Since I am Emacs user, the most common way to do this is using TRAMP (Transparent Remote access, Multiple Protcol). TRAMP is an Emacs package that let’s you treat a remote host like a local system, similar…

Minimal Boolean Formulas (2011)
28 . That's the minimum number of AND or OR operators you need in order to write any Boolean function of five variables. Alex Healy and I computed that in April 2010. Until then, I believe no one had ever known that little fact. This post describes how we computed it and how we almost got scooped by Knuth's Volume 4A…
