Bootstrapping a Type System (2010)
Magpie has reached a strange but neat little milestone on the road from “weird experiment” to “real language”: the type system is now bootstrapped. I’m not aware of any other languages where a statement like that is even meaningful (maybe Typed Scheme ?), much less true , so I’ll try to break that down.

Monotonicity Types: Towards a Type System for Eventual Consistency
A few weeks back, we published a draft of an article entitled _Monotonicity Types_. In it, we describe a type system which we hope can aid the design of distributed systems by tracking monotonicity with types....

From Ruby to Crystal: A Quick Look

Implementing VisiCalc (2003)
I'm writing this in preparation for the Computer History Museum's The Origins and Impact of VisiCalc panel on April 8th 2003. This is basically a draft and I hope to do some more editing as time permits and you should expect many typos until then. I'm also going to continue to edit and change this as I remember…

Dolphin Progress Report: February 2017
As most of you know, Dolphin was born a GameCube emulator. A lot of its core design and concepts are based around assumptions made that it would only be a GameCube emulator. And, as a GameCube Emulator, Dolphin performs admirably, with the ability to boot every single title and a large portion of the library having no…

Papers I like (part 2)
Continued from part 1. Once I was about a thousand words into describing background for GEMM, it became pretty clear that it made more sense to group the numerical math papers into one post, so her…

Zip Files All the Way Down (2010)
A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room…

Fire And Motion (2002)

What colour are your bits? (2004)
As of Summer 2024, my article "What Colour are your bits?" has been online 20 years, and people are still linking to it as a benchmark. It's clear that people still care about intellectual property in general and copyright in particular, and the difference, if any, between id...

The Aggregate Magic Algorithms (2015)
There are lots of people and places that create and collect algorithms of all types ( here are a few WWW sites). Unfortunately, in building systems hardware and software, we in The Aggregate often have found it necessary to do relatively obscure low-level things very efficiently. Many of the tricks we've devised or…

QArt – Pictures in QR code with no inherent errors
QR codes are 2-dimensional bar codes that encode arbitrary text strings. A common use of QR codes is to encode URLs so that people can scan a QR code (for example, on an advertising poster, building roof , volleyball bikini , belt buckle , or airplane banner ) to load a web site on a cell phone instead of having to…

The qmail security guarantee
Of course, ``security hole in qmail'' does not include problems outside of qmail: for example, NFS security problems, TCP/IP security problems, DNS security problems, bugs in scripts run from .forward files, and operating system bugs generally. It's silly to blame a problem on qmail if the system was already…
