Seafile Mirror - Simple automatic backup of your Seafile libraries

I have been using Seafile for years to host and synchronise files on my own server. It’s fast and reliable, especially when dealing with a large number and size of files. But making reliable backups of all its files isn’t so trivial. This is because the files are stored in a layout similar to bare Git repositories, and Seafile’s headless tool, seafile-cli, is… suboptimal. So I created what started out as a wrapper for it and ended up as a full-blown tool for automatically synchronising your libraries to a backup location: Seafile Mirror.

Docker2Caddy - An automatic Reverse Proxy for Docker containers

So you have a number of Docker containers running web services which you would like to expose to the outside? Well, you probably will at least have considered a reverse proxy already. Doing this manually for one, two or even five containers may be feasible, but everything above that will be a PITA for sure. At the FSFE we ran into the same issue with our own distributed container infrastructure at and crafted a neat solution that I would like to present to you in the next few minutes.

The power of git-sed

In the recent weeks and months, the FSFE Web Team has been doing some heavy work on the FSFE website. We moved and replaced thousands of files and their respective links to improve the structure of a historically grown website (19+ years, 23243 files, almost 39k commits). But how to do that most efficiently in a version controlled system like Git?

In our scenarios, the steps executed often looked like the following:

System Hackers meeting - Lyon edition

For the 4th time, and less than 5 months after the last meeting, the FSFE System Hackers met in person to coordinate their activities, work on complex issues, and exchange know-how. This time, we chose yet another town familiar to one of our team members as venue – Lyon in France. What follows is a report of this gathering that happened shortly before #stayhome became the order of the day.

I love the hidden champions

A few days ago I’ve sent an announcement email for today’s I Love Free Software Day to a large bunch of people. Most of the remarkably many replies have been positive and a pure joy to read, but some were a bit sceptical and critical. These came from Free Software contributors who are maintaining and helping projects that they think nobody knows and sees – not because these software projects are unused, but because they are small, a building block for other, more popular applications.

The 3rd FSFE System Hackers hackathon

On 10 and 11 October, the FSFE System Hackers met in person to tackle problems and new features regarding the servers and services the FSFE is running. The team consists of dedicated volunteers who ensure that the community and staff can work effectively. The recent meeting built on the great work of the past 2 years which have been shaped by large personal and technical changes.

The System Hackers are responsible for the maintenance and development of a large number of services. From the fsfe.org website’s deployment to the mail servers and blogs, from Git to internal services like DNS and monitoring, all these services, virtual machines and physical servers are handled by this friendly group that is always looking forward to welcoming new members.

Protect freedom on radio devices: raise your voice today!

We are facing a EU regulation which may make it impossible to install a custom piece of software on most radio decives like WiFi routers, smartphones and embedded devices. You can now give feedback on the most problematic part by Monday, 4 March. Please participate – it’s not hard!

In the EU Radio Equipment Directive (2014/53/EU) contains one highly dangerous article will cause many issues if implemented: Article 3(3)(i). It requires hardware manufacturers of most devices sending and receiving radio signals to implement a barrier that disallows installing software which has not been certified by the manufacturer. That means, that for installing an alternative operating system on a router, mobile phone or any other radio-capable device, the manufacturer of this device has to assess its conformity.

FSFE Planet has been refurbished

If you are reading these lines, you are already accessing the brand-new planet of the FSFE. While Björn, Coordinator of Team Germany, has largely improved the design in late 2017, we tackled many underlying issues this time.

So what has changed under the hood?

  • The whole system runs in a Docker container now, with all code accessible on our Git. Yes, Docker has drawbacks, but in this case it eases maintenance for our volunteers and makes contributions to design and code very simple.
  • The old planet ran on a very old Debian server which had issues with modern TLS versions. This basically erased a few blogs from the planet whose webservers do not support older encryption standards.
  • The design has been improved once more. It now more closely aligns to the design of our main page fsfe.org and feels more natively to use and browse.
  • Many blogs which were not accessible any more have been removed, and those which redirected to other URLs have been updated accordingly.

So with the migration to the new system you will probably find a few new blogs and unread posts in your RSS feeds now. So please do not be confused about it but look forward to even more useful and interesting bits from the FSFE community!

Idee: Wiki zu gesellschaftspolitischen Positionen von Prominenten

Alles begann, als mein Mitbewohner Lars und ich uns eines morgens fragten: „Mit wem würden wir lieber ein Bier trinken gehen, Thomas de Maizière oder Jens Lehmann?“.

Zu de Maizière hatten wir beide eine recht eindeutige Meinung, aber bei Lehmann waren wir uns nicht sicher, ob wir uns mit ihm verstehen würden. Lars meinte sich zu erinnern, dass er ein merkwürdiges Gesellschaftsbild hätte, allerdings zeigte ein Blick auf Lehmanns Wikipedia-Artikel, dass er gemeinnützig sehr engagiert ist. Was nun? Würden wir uns mit dem Ex-Nationaltorwart bei einem gemütlichen Bier gut verstehen oder schon nach wenigen Minuten in einer heftigen Diskussion über Geschlechterbilder enden?

I love astroid! #ilovefs

You cannot imagine how long I’ve waited to write this blog post. Normally I’m not the bragging kind of guy but for this year’s edition of my „I love Free Software“ declaration articles (after 2014, 2015 and 2016) I just want to shout out to the world: I have the world’s best mail client: astroid!

Hugo and me declaring our love to astroid

Hugo and me declaring our love to astroid

Update February 2018: Meanwhile I have published my mail config incl. astroid, notmuch, offlineimap etc. It is a rather complicated and special setup but perhaps it will help you.
