A few weeks ago I bought myself a building game called Roller Coaster Challenge. It’s a puzzle toy where you have to complete simple tracks for a marble to travel down. 🎢

Instead of solving the 40 bundled puzzles, I thought it would be more fun to generate my own.
Here is the first procedurally generated track.
After some bugs got fixed, I can set up a Mastodon bot for daily, random challenges.

I am tidying up! Getting rid of things that don't spark joy.

Because decentral hosting of version control systems has become more mainstream, I wonder if someone already wrote a script to combine contribution graphs from instances, instances, GitHub and so on.
I would like to compile it daily and host it on my website.

When you are so deep in your free software bubble, you sometimes forget, Windows and MacOS users can neither recompile their operating system nor install it on as many machines as they need.

Being able to inspect, rebuild and redeploy software on your personal devices is important for freedom and a greatly improves the longevity of devices. Open source enthusiasts know this with desktops, laptops, their phones and routers.

Sadly, these options do not yet exist for most devices. These are more valuable and secure, when modifiable and redeployable.

Bradley M. Kuhn explains how can help to keep free software free (as in freedom).

In two days I will be giving a presentation about the to the Vancouver Users Group.

Do you know any cool, open projects I should mention?

I started experimenting with which I noticed being used for the API.

Schemas are a great way to define data structures for an open exchange. They allow others to write parsers without the need to read through a lot of incomplete examples. Schemas can also help keeping your data consistent.

Does anyone know, if the differences in JSON parsers were solved?
What of your JSON data would you write a schema for?

Login walls make your articles inaccessible to your readers.

Popular websites like Twitter, Facebook, Medium and LinkedIn hold a lot of valuable information put there by individuals. They frequently get linked to from the various news sources I consume.
Often login modals pop up, preventing me from reading feeds past the most recent articles.

I am glad decentral alternatives like Mastodon and Wordpress share content without login walls. They even have RSS feeds for external consumption. 👍

And secondly, I'd like to thank @fdroidorg. You've got my second #ILoveFS this year, because you are my daily driver…

Thing is, you are more than just a small app, you're the portal to so many awesome #FLOSS apps making them only one-click away.
Actually, on a a new #Android, you are the very first thing I get. And as long as the device lives, you are it's breathe…

You've got many great improvements recently, and I am sure, you'll continue to improve and never rest.


It's #ILoveFS day again! 🎉

So my first #ILoveFS goes to #BorgBackup (short: #borg) for being a stable, reliable & secure backup solution!
You are my safe engine for backups, all day and night long. Thanks for that wonderful piece of software! 🤗 I don't know what I would do without borg, you already saved me enough times from many big threats, most importantly myself… 😃


It took me way too long to figure out, that the line of equal signs underneath an title must have the same length as the title.

For over an hour I was inspecting example files for binary differences as I thought the incorrect formatting might have been caused by a different encoding.

If a stranger on the street follows you and asks for your name and address, that's creepy. But online it is just the norm.

Actually, imagine trackers as a mob of automated robo-strangers which can remember everything they see you do. 🙃

Fight them off by using a 3rd party content blocker, like Firefox has built-in.

On Sat, 2019-Feb-02 I plan to update the shops of Metropolis at Metrotown in . It is the largest mall in British Columbia and some shops are out-of-date.
Feel free to text me some tips or come by, if you live nearby.

Would you map the opening hours on every shop in a mall or can they be added to a relation?

G-Droid 0.7.0 is now available on #fdroid . This version shows apps similar to your installed apps and apps you might also like. Give it a try! This is a new experience to browse apps of the F-Droid repository. #gdroid #Android

Another good thing: it does all these things without stealing your data to analyze it or do any kind of tracking. #deletegoogle 😍

Last year I travelled to and twice to . Without restrictions. There are so many privileges, we take take for granted as EU-citizens. Still there’s much to do in Europe, but let’s improve this Union instead of throwing away the accomplishments. 🇪🇺 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇫🇷 🇩🇪

is the public transport company for the Greater area. In we had hundreds of issues with the reference codes of bus stops.

As of today, we finally resolved all duplicate reference codes and those where the reference code was mapped as a name. That’s a great win for the quality of the map data. 🚌 🚐 🚎
