I set up mine same as I did on desktop. Copied my custom filters over and enabled all of the default ones. Works well enough.

Huh? How did you narrow it down to just GIMP? Are you excluding all non-GUI software or something? GUI has never been a big focus for GNU (which I assume is what you’re referring to when you say FSF), though they do have a couple of projects like GIMP and GNUCash. Most notably as far as GUI is concerned, they instigated the GNOME project, though they later split off. But yeah, they still maintain extremely important tools, especially for developers and UNIX systems, such as glibc, coreutils, gcc, emacs, gdb, make, bash, grub, octave, guix, etc.

At the moment, we have Blink (Chrome), Gecko (Firefox), Webkit (Safari), Servo, Ladybird and Goanna (Pale Moon).

At best, another Pale Moon is what would happen. They’ve been maintaining their own hard fork of Gecko by themselves since 2016. They clearly have people capable of maintaining a browser engine, though perhaps not quite enough of them. If Firefox were to die, perhaps joining up with Goanna would be the smart move.

There are significantly fewer Firefox-based browsers than there are Chromium-based ones, unfortunately. Out of the ones we do have:

Floorp has much like Vivaldi gone the proprietary source-available route, so you couldn’t pay me to use it.

Pale Moon is easily the most involved of the Firefox forks, being a fork of a much older version of Firefox, but I wouldn’t generally recommend it for security reasons. It does have its uses, though. Waterfox Classic is in a somewhat similar boat. Security-wise Pale Moon is definitely the better of the two because it uses its own fork of Gecko which is maintained about as well as you could reasonably expect given the manpower available to the project. Waterfox Classic meanwhile has kinda just been left to rot since most development is going to regular Waterfox nowadays, so it’s not maintained nearly as well as Pale Moon and it’s just been collecting CVEs. But for those same reasons if all you want is the ability to use legacy XUL extensions, then Waterfox Classic is gonna have better compatibility since it hasn’t been modified nearly as heavily as Pale Moon.

LibreWolf is probably the most popular Firefox fork nowadays, but it isn’t much more than a Firefox equivalent to Ungoogled Chromium. Waterfox goes a little further, but not by much. Both can be good choices, but personally I haven’t had much reason to switch away from upstream Firefox. LibreWolf is tempting, but I can already disable pretty much all of the Firefox BS from about:config, so I don’t see the point. It’s pretty much just better defaults.

FileZilla.

Is there any reason you need to switch other than the age of the last releases? Avidemux had its last release in 2022 and its last commit a week ago. For a piece of software with a fairly stable and unchanging set of features, that seems pretty reasonable to me. Avidemux still works fine on Linux and is still packaged by all of the large Linux distros, so I don’t see the problem. VirtualDub’s definitely dead, though.

Mesa + DXVK/WineD3D/VKD3D/Gallium-Nine.

CC BY-SA is considered open source. CC BY-NC is not.

I would consider the “source code” for artwork to be the project file, with all of the layers intact and whatnot. The Photoshop PSD, the GIMP XCF or the Krita KRA. The “compiled” version would be the exported PNG/JPG.

You can license a compiled binary under CC BY if you want. That would allow users to freely decompile/disassemble it or to bundle the binary for their purposes, but it’s different from releasing source code. It’s closed source, but under a free license.

Officially, sure, these are the only supported cards. In practice, it works with most AMD cards.

what do you mean? rocm does support linux and so does zluda.
