Dec 11th: I managed to miss this the first time around - Gretchen McCulloch explains the grammar behind Doge
Nov 18th: I love the sheer bloody mindedness of these fake oyster card stickers to place of your real oyster card
Nov 5th: I haven't completed all of the Regex Crossword puzzles (the hex ones get pretty tricky) but they're really nicely done
I was pretty intrigued by the Balmuda, a highly-sought Japanese toaster that claimed to produce the perfect slice of toast. Three years on and Japan's specialization in extreme attention to detail and perfection has produced the Mitsubishi TO-ST1-T bread oven, an even more ludicrous single-slice toaster. If you're outside of Japan, you'll also need a transformer to supply 100V at 930W to make it work. I'll let you know how it goes.
Jul 11th: If you use AWS Lightsail and want to collect metrics for memory usage (or anything else) using CloudWatch, it's a bit tricky. So I wrote a little tutorial on getting it set up.
May 7th: It turns out you can make a browser based chat client without using any JS or forcing page reloads. Truly amazing/evil. Probably not practical, but does show a clever mechanism for allowing some dynamic data flow with JS disabled.
May 6th: The source code to every Infocom text adventure is now on github. It's all in ZIL, which you can learn about here. Time to replay the HHGTTG game!
May 5th: It sounds like privacy works similar to the sadly defunct Final, but woks as a layer on top of your existing card. Has anyone tried it?
May 3rd: A great piece on pessimism, attitude and code quality
An amazingly detailed map of the London transport network, this time showing detailed lines and platforms.
