Enabling Continual Learning in Neural Networks
Computer programs that learn to perform tasks also typically forget them very quickly. We show that the learning rule can be modified so that a program can remember old tasks when learning a new one. This is an important step towards more intelligent programs that are able to learn progressively and adaptively.

Elixir Streams
I previously wrote about explicitness in Elixir. One of my favorite ways the language embraces explicitness is in its distinction between eager and lazy operations on collections. Any time you use the Enum module, you’re performing an eager operation. Your collection will be transformed/mapped/enumerated immediately…

Careful with that Buffer
Last week I was sorting through several sets of Microsoft C 5.1 disks from 1988 (more about that later). While I was comparing the disk images to see whether the disks were the same or not, despite different labels and part numbers, I did a double take when I realized that a file with random e-mail fragments was, in…

8086 Microcode Browser
Since releasing 486Tang , I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020.

A bug story: data alignment on x86
This sounds unusual. Who ever wants to do this in real life? Normally, we only see code like this as primary school assignments or compiler benchmarks. However, this time it happened in real life.
