In the 1960s, Brinch Hansen worked at the Danish computer company Regnecentralen, first in the compiler group headed by Peter Naur and Jørn Jensen, and, later, as the chief architect of the RC 4000 minicomputer and its…

A gentle intro to assembly with Rust
One of the things I’ve wanted to do for a while is really dig into assembly and get into the weeds of how programs actually run. A rework of the asm macro has recently landed in nightly rust so it seemed like a good time.

Timeouts and cancellation for humans (2018)
Your code might be perfect and never fail, but unfortunately the outside world is less reliable. Sometimes, other people's programs crash or freeze. Networks go down; printers catch on fire . Your code needs to be prepared for this: every time you read from the network, attempt to acquire an inter-process lock, or…

What the Heck Is Pyproject.toml?
Recently on Twitter there was a maintainer of a Python project who had a couple of bugs filed against their project due to builds failing (this particular project doesn't provide wheels, only sdists). Eventually it came out that the project was using a pyproject.toml file because that's

Decimating Array.Sort with AVX2
Decimating Array.Sort with AVX2. I ended up going down the rabbit hole re-implementing array sorting with AVX2 intrinsics. There’s no reason I should go down alone.

The Frink Is Good, the Unit Is Evil
One day Alan Eliasen read a fart joke and got so mad he invented a programming language. 20 years later Frink is one of the best special purpose languages for dealing with units. “But why do we need a language just for dealing with units?” Glad you asked! Intro to Units A unit is the physical property a number…

Fix Your Timestep
Introduction Hi, I’m Glenn Fiedler and welcome to Game Physics. In the previous article we discussed how to integrate the equations of motion using a numerical integrator. Integration sounds complicated, but it’s just a way to advance the your physics simulation forward by some small amount of time called “delta time”…

R7RS versus R6RS (2018)
InPhase asked today on #scheme about the R7RS vs R6RS debate. I followed the original debate closely and have experience both using and implementing R6RS. I also recently added R7RS support in Akku.scm 0.3.0, so I feel like I can weigh in on this. It’s a topic that many feel passionately about, and I’m also firmly on…
