May 05, 2026 [Tech] I really enjoy reimplementing things that already exist. Sometimes it’s just out of necessity, sometimes it’s to make it faster, or work in a different way, or improve the quality of the code, but I like having concrete expectations about how the code functions. So, when a colleague suggested we use […]
04 February 2019 [Java, Performance, Programming, Rabbit Escape] Series: operation, image, opacity I wanted to overhaul the UI of my desktop game Rabbit Escape to make it more comfortable and look nicer, so I looked at a new look at game-loop style graphics rendered to the canvas in a Java 2D (Swing) UI. For more […]
May 01, 2026 [Programming, Rust, Tech, Videos] Let’s fix the messy error handling in our Rust towncrier clone using anyhow library and add context() call to explain what went wrong. Can we match the output of towncrier under different circumstances? Do we really want to match it, or can we do better? You can find […]
08 February 2019 [Java, Performance, Programming, Rabbit Escape] Series: operation, image, opacity In my previous post I examined the performance of various drawing operations in Java 2D rendering. Here I looked at some specifics around image rendering, with the goal of finding optimizations I could apply to my game Rabbit Escape. You can find the […]
April 26, 2026 [Tech] Since I created this blog statically using Zola, I have been using Remark42 as my commenting system. I wanted something self-hosted and simple, and it worked. I currently get comments every few months, and about half of them are spam. Remark42 seems to forget who I am every time, so deleting […]
April 24, 2026 [Programming, Rust, Tech, Videos] Enthusiastically embracing test-driven development as usual, we attempted to write a minimal clone of a useful tool, towncrier, that allows us to create changelogs from individual “news fragment” files. In the end we had the outline of a viable solution that passed the first and only test! You […]
February 11, 2019 [Java, Performance, Programming] Series: operation, image, opacity Not because I enjoyed it, I seemed compelled to continue my quest to understand the performance of various Java 2D drawing operations. I’m hoping to make my game Rabbit Escape faster, especially on the Raspberry Pi, so you might see another post sometime actually trying […]
February 14, 2019 [bash, JSON, Keybase, Programming] I’ve become very interested in keybase.io lately, mainly because it offers secure conversations, and you can have bots. I wrote a quick bot to simulate Arnold Schwarzenegger that I thought I’d share to show how easy it is. It’s based on the keybase command line tool (which comes […]
April 17, 2026 [Programming, Rust, Tech, Videos] I was scared to do it, but it’s actually fine! This time we look at the fastest way to split a large text file into separate lines, first by implementing our own zero-copy version. BufReader::lines and then using SIMD, which allows us to process 64 bytes simultaneously, using […]
I discovered something difficult in Python, which was a first, so I wrote a whole blog series about it, and now a whole video: Slide: Async Python Basics Slide Blog posts: asyncio basics, large numbers in parallel, parallel HTTP requests, additions to stdlib PakarPBN A Private Blog Network (PBN) is a collection of websites that […]
