Sometimes I just need to look into the details of a PGP key that is provided in its “armored” form by some website (not everyone is publishing their keys to the keyservers). Normally I would have to import that key to my keyring or save it into a file and use gnupg to visualize it…

Firefox’s DoH, the good, the bad and the ugly

Easy backups with Borg
One of the oldest and most frequent advises to people working with computers is “create backups of your stuff”. People know about it, they are sick of hearing it, they even advice other people about it, but a large percentage of them don’t do it. There are many tools out there to help you fulfill…

Channels and Webhooks
Django is an awesome web framework for python and does a really good job, either for building websites or web APIs using Rest Framework.
