One decade later, Minecraft world generation is interesting again
I became a big fan of Minecraft when I first started playing it in early-2011. I have stopped in recent years since I find it dangerously addictive, though I sometimes keep up with the new changes. Today I want to look back at a development mistake that was made in Beta 1.8, one that took a decade to recover from.

All Horses Are the Same Color
Problem: Show that all horses are of the same color. “Solution”: We will show, by induction, that for any set of $ n$ horses, every horse in that set has the same color. Suppose $ n=1$, this is obviously true. Now suppose for all sets of $ n$ horses, every horse in the set has the same color. Consider any set $ H$ of…

LLVM internals, part 4: attributes and attribute groups
This is the last post I plan to do on parsing LLVM’s bitcode, at least for a while. I’ll keep working on the various libraries that I’ve started under the mollusc umbrella, but they won’t be accompanied by regular posts anymore — I’d like to refocus on writing smaller, less dense (read: lower-pressure) posts for a…

Fast CSV Processing with SIMD
I recently learned of csvquote , a tool that encodes troublesome CSV characters such that unix tools can correctly process them. It reverses the encoding at the end of the pipeline, recovering the original input. The original implementation handles CSV quotes using the straightforward, naive method. However, there’s a…

Avy Can Do Anything
Update (2024-09-08): Read this article in Japanese at Qiita or at Emacs-JP. You’re using Avy wrong. Too harsh? Let me rephrase: you’re barely using Avy. Still too broad? Okay, the noninflammatory version: Avy, the Emacs package to jump around the screen, lends itself to efficient composable usage that’s obscured by…

Firefox's Optimized Zip Format
This post is about minimizing amount of disk IO and CPU overhead when reading Zip files. I recently saw an article about a new format that was faster than zip. This is quite surprising as to my mind, zip is one of the most flexible and low-overhead formats I’ve encountered. Some googling showed me that over past 11…
