Editing binaries: easier than it sounds
Editing binaries is a trick that comes in handy a few times a year. You don't often need to, but when you do, there's no alternative. When I mention patching binaries, I get one of two reactions: complete shock or no reaction at all. As far as I can tell, this is because most people have one of these two models of the…

Planjure: A* and Dijkstra's in Om
I wrote Planjure to learn ClojureScript and Om. It’s a fun little program. You paint islands on a canvas and run path-planning algorithms to find the optimal path for your ship to traverse from start to finish. Sailing across blue ocean is faster than hiking through green islands. The three algorithms implemented are…

New partition function record: p(10^20) computed
The partition function p ( n ) counts the number of partitions of n , i.e. the number of ways n can be written as a sum of positive integers when disregarding the order of the terms. For example, 4 has the five distinct partitions 4, 3+1, 2+2, 2+1+1, 1+1+1+1, so p (4) = 5. This week, I set a new record by computing…

An upgrade to attoparsec, Haskell parsing library: more speed, more power
I’m pleased to introduce the third generation of my attoparsec parsing library. With a major change to its internals, it is both faster and more powerful than previous versions, while remaining backwards compatible.

A farewell note to a programming language
Do you remember how we first met, back in 2012? I thought your functional approach was fresh, and different. For a while I believed we were made for each other. A first project was a success; on my own I was comfortable with the good parts of you. But as soon as I started working in teams writing Scala, your immense…
