Ruby’s magic underscore
I discovered today that Ruby treats underscores a little bit differently when it comes to variable names.

Calling Rust from Python
I recently watched GOTO conferences' talk Calling Functions Across Languages by Richard Feldman. I’m afraid I have to disagree with using the term 'language' in this context. It’s a no-brainer to call Java from Kotlin or Scala or to call Java from Kotlin. Hence, in the rest, I’ll use 'stack'.

Writing and publishing a Python module in Rust
This post is a quick walkthrough of how I wrote a Python library, procmaps , in nothing but Rust. It uses PyO3 for the bindings and maturin to manage the build (as well as produce manylinux1 -compatible wheels).

Summary of C/C++ integer rules
This is my own collection of hard-earned knowledge about how integers work in C/C++, and how to use them carefully and correctly. In this article, I try to strike a balance between brevity (easing the reader) and completeness (providing absolute correctness and extensive detail).

Are pointers and arrays equivalent in C? (2009)
Longer answer: it depends on what you mean by "equivalent". Pointer arithmetic and array indexing are equivalent. In other aspects, pointers and arrays are different.

I Wrote a Compiler
I have a Computer Science degree. I attended a whole course of lectures on compilers (and have a certain fondness for “the red dragon book” as a result). However, I had never actually written a compiler from start to finish until a rainy day last weekend.

Teaching Kids Forth
Forth is uncommonly used to teach programming to kids. Scripting languages like Python and visual environments like Scratch are far more popular options. But when I got the opportunity to introduce middle and high school students to programming, I chose the stack-oriented concatenative language from 1970. I was…

How Swift could potentially be faster than Objective-C
Since the introduction of Swift, speed has been a key selling point. Indeed, it's right in the name of the language. It's said to be faster than dynamic languages like Python or JavaScript, potentially faster than Objective-C, and even claimed to be faster than C for certain cases. But how exactly does it do it?

Depending in Common Lisp
A while ago I was working on a Common Lisp library that makes use of the Metaobject Protocol . I ran into a few edge cases around dependencies between classes and it took a while for me to figure out how to solve them, so I wanted to write down what I learned in case anyone else might find it useful. This post is an…
