Today I set out to the task of upgrading a set of views crafted with the React library. The upgrade was necessary because one part of a view using React stopped working in Chrome Version 48.0.2564.116 (64-bit). I don’t know why this happened, I didn’t find anything related to it and as it stands this was probably the…
There are many legitimate arguments to be had about performance, but there are also plain old excuses. It's time to end the excuses.
wingolog: article: baffled by generational garbage collection
Clojure REPLs are used for a broad spectrum of purposes, from learning the language to data exploration to live music performance. This chapter will provide some guiding principles for applying Clojure REPLs to the more common use case of pragmatic software development.
After reading boat’s excellent post on asynchronous destructors , I thought it might be a good idea to write some about async fn in traits. Support for async fn in traits is probably the single most common feature request that I hear about. It’s also one of the more complex topics. So I thought it’d be nice to do a…
At Devoxx last week I used the phrase "Scala feels like EJB 2 to me". What was on my mind? Scala For a number of years on this blog I'v...
In absolute terms they don’t have much overhead – think sub-microsecond for most uses. Which makes them perfectly acceptable when they’re used sporadically (e.g. only a few times per second).
This is a tale of two approaches to regular expression matching. One of them is in widespread use in the standard interpreters for many languages, including Perl. The other is used only in a few places, notably most implementations of awk and grep. The two approaches have wildly different performance characteristics:
About two months ago, I decided to start developing a fresh codebase for my voxel project – something that many indie developers are probably all-too familiar with, including myself. This time around, there were three major features that I wanted to implement:
A while ago there was an interesting thread on the Julia Discourse about the “state of machine learning in Julia”. I posted a response discussing the differences between Julia and Python (both JAX and PyTorch), and it seemed to be really well received! Since then this topic seems to keep coming up, so I thought I’d…
I was fed up with the poor opportunities for abstraction in configuration formats. The many configuration languages that exist already were not invented here, so I wrote my own, at first just for fun. But then it became useful.
This is the fourth article in a series about writing my own SQL query builder. Today, we'll rewrite it from scratch, explore API design, learn when to be lazy, and look at worse and better ways of doing things – all in 150 lines of Python!

Update May 2018: This is more rant-ish than I would write now, but it’s my only post to hit the front page of HackerNews (it got to the number 2 spot back in 2010; I saved screenshots), so has a soft-place in my heart.
The design of Datalevin's compact Clojure search engine, its T-Wand algorithm, and the full-text search benchmarks comparing it with Apache Lucene.
A contemplation of how feature management tools might evolve to better support how feature flags are used in practice
Algorithms, circle mazes, hex grids, masking, weaving, braiding, 3D and 4D grids, spheres, and more!
Mimicking the operation more accurately.
