#fosdem2025 — Public Fediverse posts

Slides from my #wayland input method presentation are up now!

https://fosdem.org/2026/schedule/event/MVVELP-wayland_input_method_wrap_up/

I'm impressed by the new activity on input methods! Is that the usual post-talk excitement, or will things switch to a new gear?
We'll know in a week or so. Thank you all anyway :)

Already looking forward to #fosdem2026 despite it still being October (barely).

My first edition was #fosdem2010
(still got the shirt to prove it)

My most recent was #fosdem2025

Now that #PostgreSQL18 has been released, it's a great time to learn about and experiment with #PostgreSQL Cumulative Statistics - an excellent feature that gives extension developers support for defining new statistics.

Learn more about stats (similar to what's in pg_stat* views & functions) and how to define your own views & functions in the future from @c2main:

A great way to spend an afternoon is watching past #tech talks at conferences... no? 📽️

Well, if it's interesting enough to you, maybe take a look at "Stats roll, baby, stats roll" from Cédric Villemain, presented at #FOSDEM2025. Here, he discusses using the PACS (#PostgreSQL Advanced Cumulative Statistics) extension to explore what is offered by #Postgres as well as how to define your own new kind of statistics.

I started listening to some of the recorded FOSDEM talks. Today I listened to one about Mobilizon, https://video.fosdem.org/2025/ud2208/fosdem-2025-4381-mobilizon-decentralizing-event-management-for-a-privacy-respecting-social-web.av1.webm . I knew it is being used for organizing protests, but I didn't really appreciate the potential. I'm thinking it could be useful for family and neighborhood events. It's exciting!

Here's a short, funny and inspiring talk by Michal Pleban at last month's #FOSDEM2025 about getting the ultra-rare, cancelled #Commodore 900 up and running with #Coherent #UNIX.

Putting some of those #fosdem2025 stickers to good use on my #opensuse #macbook 2014 project. Apparently using a browser for too long makes the poor boy sweat. But at least he looks fancy now.

(Also, #debian “people consensually doing things together” must be one of my all time favourites.)

With Allison, I presented at FOSDEM how we can combine UKI, composefs and containers to build a fully signed boot chain. The slides and the recording are now available: https://fosdem.org/2025/schedule/event/fosdem-2025-5191--signed-sealed-and-delivered-with-ukis-and-composefs/

This is how we are planning to bring boot chain integrity to Bootable Containers.

This is a follow up on the initial work that we presented last year at @allsystemsgo: https://cfp.all-systems-go.io/all-systems-go-2024/talk/HVEZQQ/

After watching the #smolbsd presentation at #fosdem2025 I was tald there was a longer video on the subject. Loved this video.

One of the highlights of #FOSDEMJunior was the #CoCube workshop run by Shuai Liang and Jialing Han. This is a best educational robot I've seen in years :)

Hello from Meta Belgium, on yet another unseasonably sunny day in #Brussels! Hosting a @centos #CentOS #documentation and #website / #systemd #hackathon

Thanks to @mozillaofficial for my really nice #FOSDEM2025 shirt

I received some stickers today to share around with members or other people who like the Linux Musicians Forum.
If you happen to be around in Belgium someday, we can catch up.
Thanks to @raboof for sharing and Jarle for designing 👌👍

What a great idea to update TMI Pics the #Pixelfed instance on my #YunoHost server right now, at the end of #FOSDEM25, as if I don’t have any more urgent things to do or places to be… Never trust me as your #sysad, please!

🚀This morning at #FOSDEM2025, our won Rob Van Kranenburg was on stage spotlighting Disposable Digital Identities!

In the session “We need Disposable Digital Identities for a more secure and resilient digital society”, Rob and the team explored:

Going thru the stands at fosdem ran into immich.app as a photographier I was interested so asked a few questions :
- what's your biz model?
- none yet, but probably hosted services
- how do you compare to #flickr or #pixelfed?
- pixelwhat? We are providing a replacement photo - no direct answer for flickr
- do you support activitypub?
- actiwhat?
- do you run on any OS?
- of course we do, we provide docker images
