Secret Military Telephone Buttons
It's the first of the new year, which means we ought to do something momentous to mark the occasion, like a short piece about telephones. Why so much on telephones lately?

WebDAV isn't dead yet
I should have titled this post “I hate S3”. 📢 What is the status quo? FTP is dead (yay), SFTP is too dependent on SSH and unix authentication. AWS made S3 pervasive and now every webapp that needs to store files assumes you’ll be able to connect it S3. This …

Freenode IRC operators now engaging in routine abuses of power
There have been several allegations of this since the handover of the Freenode infrastructure to its new custodians, but I can now provide a first-hand account of one incident — because I am the victim of it.

Some categories: Geographical (countries, cities, parks, rivers, lakes, streets), entertainment (flintsones, simpsons, disney films, celebrities), companies (hotels, airports, local shops, restarants)…
