Hyper-Text Transfer Protocol is, by some measure, the most popular way for computers to talk to each other on the Internet1. Generally speaking2, clients (like browsers) talk to servers using a set number of HTTP "verbs". This tells the server what sort of thing the client is trying to do. The two most popular3 verbs…

As part of my new job, I'm learning a lot more about the mysteries of the Domain Name System than any mortal should know I thought possible. The humble unix dig command allows you to query all sort of DNS information. For example, to see name server records for the BBC website, you can run:…

There is a thoroughly modern story coming out of Ireland: Drones are being used routinely around Irish racecourses to take advantage of a short time lag between broadcast footage of events and the action on the ground.

Way back in the 1990s, the word "Netizen" was coined. I always took it to mean "someone who lives on the Internet". In modern times, the neologism has been superseded with "webizen".
