Game Programming Patterns: Event Queue (2014)
Unless you live under one of the few rocks that still lack Internet access, you’ve probably already heard of an “event queue” . If not, maybe “message queue”, or “event loop”, or “message pump” rings a bell. To refresh your memory, let’s walk through a couple of common manifestations of the pattern.

Fragile narrow laggy asynchronous mismatched pipes kill productivity
Something I’ve been thinking about recently is how when I’ve worked on any kind of distributed system, including systems as simple as a web app with frontend and backend code, probably upwards of 80% of my time is spent on things I wouldn’t need to do if it weren’t distributed. I came up with the following description…

In 2007, I was offered $120,000 to buy this blog outright. I was sorely tempted, because that’s a lot of money. I had to think about it for a week. Ultimately I decided that my blog was an integral part of who I was, and who I eventually

Why are we templating YAML?
I was at cfgmgmtcamp 2019 in Ghent, and did a talk which I think was well received about the need for some Kubernetes configuration management as well as the solution

Web Components Eliminate JavaScript Framework Lock-In
Web components can dramatically loosen the coupling of JavaScript frameworks. To prove it, we're going to do something kinda crazy: build an app where every single component is written in a different JavaScript framework.

Defer available in gcc and clang
About a year ago I posted about defer and that it would be available for everyone using gcc and/or clang soon. So it is probably time for an update. Two things have happened in the mean time: A tec…

Standard Markdown Is Now Common Markdown
Let me open with an apology to John Gruber for my previous blog post. We’ve been working on the Standard Markdown project for about two years now. We invited John Gruber, the original creator of Markdown, to join the project via email in November 2012, but never heard back.

Faster asin() was hiding in plain sight
This one is going to be a quick one as there wasn't anything new discovered. In fact, I feel quite dumb. This is really a tale of " Do your research before acting and know what your goal is, " as you'll end up saving yourself a lot of time. Nobody likes throwing away work they've done either, and there could be…

It is no secret that I am not a fan of logs; I’ve baited (rapala in work lingo. Rapala is a Finnish brand of fishing lure, and used to mean baiting in this context) discussion in our work chat with things like: If you’re writing log statements, you’re doing it wrong. This is a pretty incendiary statement, and while…

Translating a Fortran F-16 Simulator to Unity3D
I recently purchased the textbook “Aircraft Control and Simulation” by Brian L. Stevens, Frank L. Lewis, and Eric N. Johnson 1 . This book covers the control and simulation of aircraft. It’s really dense and frankly hard to understand. As far as aerodynamics texts go, it’s pretty typical.
