Ein Jahr didaquiz.ch! 🎉 Was als Prototyp begann, ist heute ein modernes Baukastensystem für den digitalen Unterricht.Die Bilanz nach 12 Monaten macht mich richtig stolz:
🚀 203 Übungseinheiten mit 1'378 interaktiven Elementen sind entstanden.
🌍 64% davon sind komplett öffentlich zugänglich – echtes #OER (Open Educational Resources)!
📱 Über 300 Schüler:innen nutzen die Plattform für schnelles, notenfreies Feedback.

🛠️ Tech meets Pädagogik:
Unter der Haube setzen wir konsequent auf moderne #WebComponents und den offenen #Bitmark JSON-Standard. Die beliebtesten Aufgabentypen im Klassenzimmer: Der klassische Lückentext. KI-Erstfeedback zu freien Textantworten. Die KI entlastet beim Korrigieren, aber die Lehrperson behält immer die volle pädagogische Kontrolle.

📄 Best of both worlds: Weil digitaler Unterricht Flexibilität braucht, lässt sich jede Übung mit einem Klick sauber auf A4 ausdrucken. Ein riesiges Danke an alle Lehrpersonen fürs Nutzen und Testen! Auf das nächste Jahr! 🥂

Excel has a thing for getting dates wrong (the (in)famous 1900 leap-year bug, inherited from Lotus 1-2-3 and never fixed), and when Excel gets dates wrong, no other software does it worse. [..] The HUGO Gene Nomenclature Committee was forced in 2020 to rename dozens of human genes – including SEPT1 and MARCH1 – because Excel kept silently converting their symbols to dates. Rather than going to Microsoft and demanding a bug fix, scientists preferred to throw years of established nomenclature down the drain to avoid upsetting Redmond

I really like these two examples, not because of the issues as such, but as two examples of how people usually handle bugs in proprietary software: ignore them or work around them, but almost never complain about the software.

MS Office is always mentioned as the standard, and everything has to be as good as MS Office if people consider different solutions. But in the end, it's not because MS is so much better. People are just used to it and how to work around strange issues that they would never accept in a Free Software solution.

I just finished the first version of a small software for managing the balcony solar plant of some family members. It works completely without any cloud or any other people's computers or even an internet connection.

There's three panels and an inverter with a battery. Any power initially is used in the household, then if anything is left it's put into the battery for later use, or if the battery is full, fed it into the public grid (to get a small financial compensation). Or if you want to, you can override that and just charge the battery, or even charge it from the grid.

Of course the inverter originally needs a cloud connection and comes with an app that needs a cloud connection and obviously is described as AI-powered very smart whatever. But there is a documented API for getting and setting some values! Interoperability! Without the cloud, there's hardly any logic built in. So I had to create it myself.

It's just a few HTTP requests, json, a SQLite database, and some very basic HTML.

Final reminder: The deadline for applications to join the #SovereignTechStandards network is Tuesday, 19 May 2026, at 23:59 CEST.

Open standards shape the digital infrastructure we all rely on. But standards are only as good as the expertise behind them.

Wikipedia has a pretty good list showing all media file formats, their history, and which are proprietary, or open source. The Open Document is on there (ODF), but it's just one of many formats, that together, establish the foundation for Digital Sovereignty.
