GUADEC + Unconferences | 2017

This year’s GUADEC was amazing. I’m really happy I could attent it this year (even though my tasks are accumulating and I’m really afraid to look at my emails again…). I’m still in Manchester so, if anyone wants to meet me and buy me a tea, do get in touch!

There were quite a few talks that I enjoyed. I can’t really name one that I liked the most, but on the top of my list are:

I had a special interest in Richard’s talk. He raised many relevant questions and exposed how complicated it can potentially be the problem of donations and payments. More about that in the future.

Calendar & To Do

I had the chance to sit down and see a power user interacting with GNOME Calendar. It was an unique and enlightening experience. I was able to see a few areas where Calendar can do better in terms of UI/UX.

Unfortunately, GNOME To Do didn’t have the same luck. I’m still somewhat unhappy with the current UI of To Do, but I’m running out of ideas on how to improve it without a complete rewrite (which I simply don’t have time to do now). If you’re a GNOME user with any kind of background on design, ~please~ get in touch: I’d love to gather some feedback on To Do!


I had the chance (and honor) to be present at the discussions for GTK4. In these discussions, we did a big list of topics and discussed each one of them in details.

I admit that, during these discussions, I felt like a kid at times – the GTK hackers are incredibly smart and skilled people. The other side of the coin is that, while I was feeling like lagging behind them, I also felt honored and happy to be surrounded by such amazing people.

The biggest problem to solve now is the accessibility stack. After digging into the topic and clarifying how it works, we concluded that this topic was too big and complex for that moment, and deserved a hackfest of its own. We’ll organize one during the next months.

Wrapping up, I can’t state how productive these discussions were. Thanks to Matthias Clasen, Benjamin Otte, Christian Hergert, Cosimo Cecchi and everyone else that drove the discussions. We now have a solid GTK4 roadmap that I’ll move to the GNOME Wiki in no time.


An unexpected thing happen during the Unconference days. When talking to my good friend Mario we asked ourselves: how can we improve our own Endless tasks by upstreaming our features?

Endless OS shell has many features that GNOME Shell doesn’t, and maintaining downstream patches is expensive and simply not cool. One of these features was specially important, as it is difficult to maintain and lots of GNOME users frequently ask for.

This specific feature was considered in the past, but had many design constraints and we end up never solving it design-wise, nor implementing it.

This is about to change.

After a rather spontaneous group discussion, we found solid solutions for all the relevant edge cases of this feature 🙂  I’m sure Mario will write about it in the future, and probably will implement it as well, so stay tuned!

Because, in case you forgot:

(And yes, I purposely didn’t say which feature I’m talking about – but I’m sure many of you can guess that :P)


After a long explanation and discussion with Florian Müllner (and of course, getting him a well deserved beer for being the GNOME Shell and Mutter maintainer!) the path for quarter-tiling is much clearer now.

The original idea is to implement tiling support using constrained edges, rather than tiling states. But this is hard, and now I believe it’s effectively impossible to do that.

Olivier Fourdan tried to propose a Wayland protocol for that, but discussion ended up freezing and no progress was made for a long time. I admit I’m kinda scared to try to send  these changes upstream… see the bug’s feedback (sometimes I forget that the GNOME community is much more welcoming than many other FOSS communities).

I now have a real problem to solve, and the time is not enough. Perhaps it’s time to declare bankruptcy?


I’d like to thank the GNOME Foundation for sponsoring me. I sincerely hope that my engagement and contributions pay off this investment!

I also thank my employer Endless to let me join. The upstream contributions we’re doing are valuable for the community, and in turn it helps us lowering the number of downstream changes to maintain.
