  Compared to last year we had more than 100x the users on @foss_public_alert_server for this year's national alert test in Germany. And it showed the same bottlenecks we had already seen during the recent heat waves: notification delivery is slowed down and eventually stalls entirely due to about 40% going to push servers that rate limit under such conditions. Mozilla's and #KDE's push servers carried the bulk of the notifications, without hitting limits.

  Off to Graz for #Akademy2026! Passing through three capital cities along the way, on a single train.

  #Akademy2026 starts today! At 17:55 I'll talk about how we use continuous delivery (CD) builds for Itinerary, and show a way how we could potentially reduce the entry barrier for contributing to #KDE applications - https://conf.kde.org/event/11/contributions/319/

  My impressions from #KDE's #Akademy2026 in Graz last week: https://volkerkrause.eu/2026/10/03/kde-akademy-2026.html Lots of stuff to work on and follow up with :)

  Off to Bern for #OpenTransport2026! Four days of learning, connecting and collaborating around topics relevant for #Transitous and #KDE Itinerary :)

  Celebrated 30 years of #KDE with a few people yesterday. Not only were there active contributors who hadn't been born yet when this all started, there were also kids who's parents have met via KDE. It's amazing how multi-generational this has become :)

  Some of my impressions from #OpenTransport2026: https://volkerkrause.eu/2026/10/17/open-transport-community-conference-2026.html It's amazing how this community has come together in recent years from various fragmented/local efforts and across roles and organizations. Unsurprisingly we can achieve a lot more when we collaborate. A bunch of things seen as "normal" today (such as #Transitous) I would have considered entirely out of reach not too long ago. And this is al...

  Support for the xx-cutouts-v1 #Wayland protocol landed in #Qt yesterday, which means Qt's SafeArea API will then also work with Wayland compositors supporting this protocol. So far only @phosh@social.phosh.mobi implements this on the compositor side, now #KDE apps will have the means to stay away from display cutouts/notches there automatically, reusing all the work we have done for this on the app and framework level for Android already. #LinuxMobile

  At HTW Berlin in Schöneweide for working on tagging and modelling issues of indoor spaces in #OSM. Some of this has proven challenging over the past years as it requires to carefully balance easy mapability and maintainability, the needs of 2D, 3D and tactile rendering, graph- and area-based routing, BIM compatibility, and being able to model all accessibility-relevant properties. Let's see if locking people from all those areas in a room for two days helps :)

  On the way back home from joining the @FOSSGISeV Community Meeting at Linuxhotel in Essen for two days, for working on various organizational details for the @opentransport conference. We should be able to open the registration soon, later than originally anticipated but at least we wont have to run a 100+ attendee conference as a few individuals without a legal entity behind this anymore. #OpenTransport2026

  Experimenting with adding international flights to @transitous. Performance seems to hold up and we indeed get working multi-modal door-to-door routing from e.g. Brussels to Tokyo. There's a few issues with the router cheating around minimum transfer times that need to be sorted out before this could be deployed though.

  The #OSM Hack Weekend at @geofabrik in Karlsruhe hasn't even started yet and my first agenda item is done already thanks to running into the right people on the way: A WFS/OGC layer for @foss_public_alert_server. At the #CAP Implementation Workshop two weeks ago this was presented as something so far only offered by a commercial entity, but it looks like we could provide this easily enough as well, a prototype was done in time for dinner.
