RFCs: Blueprints of the Internet

Think about it for a second: could the internet exist without standards and protocols? Of course not! Computers need shared rules and agreements to communicate with one another. Even human languages, like English, work much the same way. They function as a kind of communication protocol because we’ve all agreed on…

Advent of Code on the Z-Machine

Fantasy consoles like the Pico-8 are a great idea. A fantasy console provides a standardised and portable environment in which developers can explore ideas within creative constraints. The Z-machine , developed by Infocom in 1979, is the earliest fantasy console I know, although this is probably the first time it’s…

Vetinari's Clock (2011)

In the excellent Discworld series the character Lord Vetinari has a clock in his waiting room which is designed to tick irregularly in order to make his visitor feel ill at ease.
