The Internet Lottery™ for content creators
Your cursor hovers over the post button. This will be the one. You researched it, you checked it, you got the graphics, and you have the audience. Today you’ll have that successful […]
Invented here syndrome
Are you afraid to write code? Does the thought linger in your brain that somewhere out there somebody has already done this? Do you find yourself trapped in an analysis cycle where […]
Essential code for lists and vectors in an interview
Lists are perhaps the fundamental data structure in code. There’s virtually no program that doesn’t use lists. Interviewers love asking questions that involve lists, either intentionally, or just because almost everything uses […]
Stop waving the wand of magic numbers
37. You have no idea what that number is, do you? A number without context nor a label is a random value. It doesn’t tell us anything. Imagine walking by a billboard, […]
How does a mutex work? What does it cost?
Concurrent programming requires synchronization. We can’t have more than one thread accessing data at the same time; otherwise, we end up with a data race. The most common solution is to wrap […]
How to fail a programming interview
I’ve conducted many interviews. There are many reasons why I reject people, but there are recurring themes. I want to give a list of the most common problems. A few of these […]
Of course HTML is a programming language
Is HTML a programming language? I could express a bit of shock, even dismay, at the question, but instead, I’ll try a more polished approach. In some sense, it may be a […]

Would you program a human?
With tales of Crispr babies in the news, I’ve been pondering the implications of programming human beings. This may or may not have been spurred by a crime novel I recently read, […]
We don’t need a ternary operator
A staple of compact code, the ternary operator ?: feels like it’s earned a place any programming language. I use it often; you should use it often. However, I don’t like the […]
ELI5: The filter, map, zip, and reduce operations
You’ve baked a fresh batch of gingerbread cookies. A bunch of little men, snowmen, stars, and bells are cooling on some trays. You clean up the table and lay out the colours […]
Sadly, I must say goodbye to Leaf (my programming language)
This is hard to write, or rather, it’s a hard decision to make. After investing many years on Leaf — a programming language, a major life project — I need to take […]
Creating a local screen overlay for streaming (OBS, Linux)
My new computer has a larger screen than the last one. It’s great, except it no longer matches the typical 1920×1080 streaming dimensions. I can’t adjust those dimensions without suffering scaling issues […]
ELI5: Algorithmic time complexity
Our favourite hobbies, like baking cookies or painting pictures, take time. Let’s ask a question though, does it take longer to bake one cookie or paint one picture? It’s hard to answer. […]
