Rebooting a 15 year-old game written in D – Part 1 Compiling
While exploring D recently, I remembered a game I played while at university 15 years ago. For a long time, I couldn’t remember the name at all, only that it was from a Japanese developer. After some search wrangling, I finally managed to find the name of the game: Torus Trooper!

DRY Is a Trade-Off
DRY, or Don't Repeat Yourself is frequently touted as a principle of software development. "Copy-pasta" is the derisive term applied to a violation of it, tying together the concept of copying code and pasta as description of software development bad practices (see also spaghetti code ).

Far Cry: How the Fire Burns and Spreads (2012)
INTRO A few years ago, I got the opportunity to architect and code the fire propagation system in Far Cry 2. At that time, it was a gigantic task and it scared the hell out of me. Luckily, it turned out well enough. With the upcoming Far Cry 3, several people recently asked me how

What I wish someone had told me about tensor computation libraries
I get confused with tensor computation libraries (or computational graph libraries, or symbolic algebra libraries, or whatever they’re marketing themselves as these days). I was first introduced to PyTorch and TensorFlow and, having no other reference, thought they were prototypical examples of tensor computation…

Shitlist Driven Development (2016)
Recently the team I work with completed a project to allow Shopify to run in multiple datacenters . This project was a refactoring project in disguise. When you undertake large refactoring of a code-base with 100s of developers and 100,000s of lines of code, you can’t align by sending an email. The merge-conflicts a…

Being good at coding competitions correlates negatively with job performance
A couple of days ago I watched a How Computers Learn talk by Peter Norvig. In this talk, Peter talked about how Google did machine learning and at one point he mentioned that at Google they also applied machine learning to hiring. He said that one thing that was surprising to him was that being a winner at…

Pointers Are Complicated II, or: We need better language specs
Some time ago, I wrote a blog post about how there’s more to a pointer than meets the eye. One key point I was trying to make is that just because two pointers point to the same address...

Apple M1 vs. Ryzen 3900X vs. Intel I9 in Software Development
I'm pretty impressed by what I've seen with Apple's M1 Chip. It's really fast and powerful for essential everyday tasks, which include browsing the web, working with Intel-based apps, and using programming apps. Yes – the ecosystem is moving, and that may take time, but I think M1 is worth paying

Why software ends up complex
Complexity in software, whether it’s a programming languages, an API, or a user interface, is generally regarded as a vice. And yet complexity is exceptionally common, even though no one ever sets out to build something complex. For people interested in building easy to use software, understanding the causes of…

Vim Creep (2011)
It all started out innocently enough. You experimented with it once or twice in your first year of college, but Nano and Pico were easier—closer to what you had already been using during high school on the Windows machines and Macs. But as time went on and you got more experience under your belt in the college-level…
