Formalising a new proof that the square root of two is irrational
Recently, somebody shared on Twitter a new proof of the irrationality of √2. Its claimed advantage is that “it requires no knowledge of mathematics above the definition of what it means for a number to be irrational, and can be written almost in one line.” These claims are dubious: the usual proof, which I’ve…

Rust concepts I wish I learned earlier
This past month, I have been enthralled by the Rust programming language given its unique edge for writing memory-safe, modern programs. Over the years, several languages have emerged as the most preferred by engineers to write resilient, backend software. The tides have shifted from Java/C++ into Go and Rust, which…

Hello, PNG
PNG is my favourite file format of all time. Version 1.0 of the specification was released in 1996 (before I was born!) and the format remains widely used to this day. I think the main reasons it stuck around for so long are:

Why we need to know LR and recursive descent parsing techniques
A couple of people have asked me for my thoughts on part of an article from Tiark Rompf called (roughly) “ Just Write the Parser ” which advocates the use of recursive descent parsing over more “formal” approaches to parsing, at least in the context of teaching compilers. I’m fairly sure I read this article a couple…

I don't understand terminals, shells and SSH
Confession time: I don't fully understand how terminals, shells and SSH really work (and my guess is you don't either). And I don't mean the cryptography behind SSH. I mean how SSH and the terminal — and the shell for that matter — interact with one another.
