Data notation in Clojure
Homoiconicity (code as a data structure) is one of the pillars of the Clojure language. It gives the extensibility and flexibility to the language.

Ignoring bulk change commits with Git blame (2019)
A long-standing objection to making bulk changes to code using automated tools (e.g. to conform to a given code style) is that it clutters the output of git blame. With git 2.23, this does not have to be the case anymore! In this post I will start by explaining the value of git blame and […]

Learn by reading code: Python standard library design decisions explained
On your Python learning journey, you may have heard that a great way to get better is to read code written by other people. That's true, but finding good code to study is not easy, mostly because the design philosophy and the reasoning behind the code are rarely documented. The Python standard library is special in…

Data-oriented design or why you might shoot yourself in the foot with OOP (2009)
Picture this: Toward the end of the development cycle, your game crawls, but you don’t see any obvious hotspots in the profiler. The culprit? Random memory access patterns and constant cache misses. In an attempt to improve performance, you try to parallelize parts of the code, but it takes heroic efforts, and, in the…

Problems with math rendering on the web (2020)
Since I first started working on my website at age fourteen, the site has gone through many revisions, and hopefully changed for the better. This blog was originally dynamically served using a Python/Flask backend, having a custom login system and post “editor” (just an input box). One of the more strange things about…

Let's code a TCP/IP stack (2016)
Writing your own TCP/IP stack may seem like a daunting task. Indeed, TCP has accumulated many specifications over its lifetime of more than thirty years. The core specification, however, is seemingly compact[^tcp-roadmap] - the important parts being TCP header parsing, the state machine, congestion control and…

Goodbye C++, Hello C
Part 1 of this series about my toy renderer covers the most fundamental design decisions. Over the years, I have written many renderers and for a long time their complexity kept growing. This time, I took the opposite route. I wanted to maximize the fraction of code that implements crucial functionality rather than…

Go 1.17 is deprecating the traditional use of 'go get'
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Subclassing in Python Redux
The conflict between subclassing and composition is as old as object-oriented programming. The latest crop of languages like Go or Rust prove that you don’t need subclassing to successfully write code. But what’s a pragmatic approach to subclassing in Python, specifically?
