Kaniko: Build container images in Kubernetes
Building images from a standard Dockerfile typically relies upon interactive access to a Docker daemon, which requires root access on your machine to run. This can make it difficult to build container images in environments that can’t easily or securely expose their Docker daemons, such as Kubernetes clusters (for…

Watching Go's new garbage collector move through the heap
Go 1.26 made Green Tea the default GC. We observe its cache-friendliness with perf, visualize the heap to see how Go allocates, and poke at a sparse-page problem a non-moving collector like Go's struggles with.

Introduction to TCP and Sockets (2001)
This section is an introduction to TCP/IP programming using a sockets API. (Sockets can also be used to work with other network protocols, such as IPX/SPX and Appletalk, but that is beyond the scope of this document.) The standard socket API was originally developed in the Unix world, but has been ported to OS/400 as…

Simulation Islands
Island management is a fundamental low level feature of physics engines and can have a big impact on solver design and performance. This was one of the first problems I decided to work on for Box2D version 3 (v3). Since I began working on v3 I’ve been comparing several algorithms for island management. My goal has…

Do We Worship Complexity?
Complexity is the most important challenge in software development. So it is important to always strive to eliminate complexity. But sometimes we worship complexity - and that can make complexity problems unsolvable.

Cognitive Biases in Software Development
A couple of years ago, I started my first job as a programmer. On the first day, I entered the office, sat in my new chair, turned on the computer, checked out a project from the version control system and opened it in IDE. The first-ever piece of the code I saw looked like that: // TODO it works, but it's ugly…

It’s been a fascinating two years, and while I am excitedly looking forward to what I’ll be doing next, it’s likely I will continue to write Haskell in my spare time. I’ll probably even write it again…

The Hacker Way: How I taught my nephew to program
Over the last year, my 13 year old nephew developed a love for hacking. From anime chat , to snake , a minimal twitter , a blog , to an anime music startup , he’s built some cool stuff (1). What I’m most proud of though, is that he’s done this with self directed play, rather than with a rigid curriculum.
