OAuth2 with Nextcloud (Provider) and GitLab (Client)

I recently configured GitLab as a OAuth2 client to a Nextcloud Instance. I wanted OAuth2 to be the only way of logging in, and Nextcloud to provide the information needed for one-click user signup (actually, three clicks). This process was not entirely straightforward, especially since I don’t want my buttons to read “OAuth2-Generic”. Changing the name after setting everything up, means changing URLs and in combination with Nextcloud this means recreating your tokens. Long story short: I wrote down how I did it.

Key Signing Party Handout Template

I organized a Key Signing Party a few weeks back and created a handout for every attendee. It featured the keys to be signed and also basic instructions to complete the signing process. It may come in handy for other organizers, so i wanted to share it with you. It’s an OpenDocument format, which should open well in just about any version of LibreOffice, OpenOffice and probably MS Office. I’m placing this under the Free Documentation License.

Roomba-Beobachtung für Eilige

leerIch habe mir einen Roomba angeschafft. Es gibt einen Haufen Staubsauger-Roboter von vielen Herstellern, ich habe mich aber wegen dem Bastelfaktor für diese Modellreihe entschieden. Gebastelt habe ich leider bisher noch nichts, dafür wurde ich jetzt schon öfter gefragt: “putzt der denn wirklich überall?” Und ich habe darauf bisher mit der Antwort aus iRobots Marketing-Material geantwortet. Dieses besagt, dass natürlich im Rahmen der Möglichkeiten an allen Stellen mehrfach geputzt wird.

Seinem Staubsauger bei der Arbeit zusehen macht zwar eine Weile auch mal Spaß, aber das Ziel ist es ja, Zeit zu sparen. Deswegen habe ich die Beobachtung automatisiert. Das hat zwar länger gedauert als den Vorgang einmal komplett zu beobachten, dafür habe ich nun aber belastbare Dokumentation. Wie ihr etwas ähnliches mit Hausmitteln (PC, Webcam, Open Source Software) nachbauen könnt, erfahrt ihr im Folgenden.

Evaluating TextSecure Part 2 – Dependency Tree

This is part 2 in my series on TextSecure. Go back to part 1, if you haven’t read it. The analysis took place at the end of february 2014, using revision 5a62856e (current master at that time).

This part will cover basic project dependencies. The dependencies are important, because they will tell us, what code makes up our project. In projects of this size, there’s usually a nice portion that’s not actually written by the project authors themselves.
