Wayland compositors use IPC over a UNIX socket to communicate with Wayland clients. To increase security and enable sandboxed applet support, COSMIC applets use the security-context protocol for their IPC connection to the compositor. To be an applet, COSMIC applications use the layer-shell protocol to behave as an applet. Neither of which were made for COSMIC. Some other Wayland compositors support these protocols. You can see which compositors support the protocols at the bottom of the wayland.app protocol pages.

In practice, because Rust libraries are always statically-linked, the MPL-2.0 is equivalent to the LGPL in spirit. Meanwhile, because of the static linking restrictions in the LGPL, the LGPL is effectively no different from the GPL. Hence, you’re going to find a lot of open source copyleft projects from the Rust ecosystem preferring either GPL or MPL-2.0, where MPL-2.0 is used in libraries where LGPL would have used previously in C projects. Dynamic linking is essentially going the way of the Dodo.

The Linux kernel already allows proprietary modules via DKMS, and a handful of vendors have been using this for decades, so this is no different. Case in point: NVIDIA driver, and Android vendor drivers.

All source code in Rust is statically-linked when compiled, which thereby renders the LGPL no different from the GPL in practice. For Rust, the MPL-2.0 is a better license because it does not have the linking restriction.

Niri is also based on the smithay library we use for COSMIC, so there’s some collaborative work between COSMIC and Niri on Smithay.

applets live in their own process and communicate via Wayland protocols (behind a COSMIC API)

Even better. A COSMIC API was not necessary since Wayland protocols already exist for this (layer-shell and security-context).

It already is available. See the links on the COSMIC webpage: https://system76.com/cosmic

No, we won’t be spending any development time on porting all of the patches in 22.04 to 24.04. GNOME is done.

You should stop using Linux then. The Linux kernel, along with many open source software, is developed and sponsored by for-profit organizations. Either directly or indirectly. Without them, open source wouldn’t be able to thrive.

I’d recommend spending some time reading about it. It’s not as hard as he thinks. Applications developed for Linux are quite easy to port to Redox. It supports many of the same system calls and has a compatible libc implementation. The kernel does have abstractions to ease the porting process. And if you’re going to make a new kernel today, you should do it right and make a microkernel like Redox. One of the benefits of having a microkernel is that it doesn’t matter what language you write drivers in. They’re isolated to their own processes. Rust, C, C++, whatever.

It does work like this, but as with justice, the wheels can be slow at times.

It is required to install system updates before using the alpha.

How so? 22.04 is actively maintained and updated by Ubuntu, and is still the latest LTS release. On top of that, the most important packages in Pop!_OS are updated frequently, so we are on Mesa 24.0.3 and Linux 6.8.0. As for when COSMIC releases, you should read last month’s blog post.

Did you not read the blog update? That is exactly what the blog update covered… The user’s theme colors are applied to the Adwaita theme used by GTK4/libadwaita, and GTK3 theme support is provided by adw-gtk3.

Are you interested in contributing? You can find the source code for theme generation here and here.

All desktops use the Super key nowadays. Sway, i3, GNOME, Plasma, etc. are all using the Super key. Have been for years. The standard convention is that the Super key is reserved for system-level shortcuts handled by the window manager; and Alt key shortcuts are reserved for application-level shortcuts. Your desktop might have bound both Alt and Super because of legacy reasons.

You might be surprised how much disk space those GNOME Circle applications actually require, despite being dynamically linked to a lot of GTK/GNOME libraries. Unless they’re written in a scripting language, they’re much closer to a COSMIC application than you think.

I don’t see the issue with an application having a static binary within the realm of 15-25 MB. Even if you had 100 applications installed, that’s only 2 GB of disk usage.

That is to show the icon theme feature.

I wouldn’t rule out the possibility of a cosmic-applets-community package which bundles third party applets, or the gradual inclusion of popular applets into cosmic-applets. Given that an applet would only become popular if there’s a lot of need for those use cases, then it would make sense to open a path to getting them mainlined.

This video is very outdated by 3 months. Although I’m not sure if COSMIC has been on The Linux Experiment since then.
