Code review without your glasses
You’re part of a preternaturally enlightened dev team, and have set aside an entire day for nothing but code review. However, after the first 2 hours, you realise that you have forgotten your glasses and have just been staring at colourful blurs all morning. What do you do?

Algebras we love
If you work with anything that can be modeled mathematically, you most likely know that many things you work on can be expressed with algebras. However, if you are not a graduate of a computer science course or similar you might not know how ubiquitous they are and how often you rely on some of them. (And I don’t mean…

A Map of Python
PyPi, the Python Software Foundation's package repo, counts over half a million open source projects. Since I use many of these every day, it seemed appropriate to get to know this set of packages better, and show some appreciation. The index website provides nice search and filtering, which is good when looking for…

Implicit In-order Forests: Zooming a billion trace events at 60fps
In the course of trying to figure out how to smoothly zoom timelines of a billion trace events, I figured out a cool tree structure that I can’t find elsewhere online, which it turned out two of my friends have independently derived after not finding anything on their own searches. It’s a way of implementing an index…

Never trust a programmer who says they know C++
I’ve been in an interviewing mindset for awhile and I’ve come to realize something important about C++ in particular. C++ is a “two peak” language. That is to say C++ is the only language I know of where two very different sets of programmers consider themselves well versed in the language. Let me show you in fake…
