It’s possible that it’s not supported on your arch.

The only thing Samba is really great for is interop with Windows. If that’s not an issue, Dolphin can browse SFTP directly by adding it as a network share (you may need to setup a password-less key pair to avoid having to login). SSHFS is a similar option and works even if the client is totally naive (it just looks like any other mounted FS).

Right. GCC -f optimizations are basically like “how hard are we going to try to be clever” and are, I believe, orthogonal to the actual instructions used. Machine dependent args start with -m, like -march or -mavx etc.

For XP, the machine KVM presents as may be too new, but that isn’t an issue with non-virtualized QEMU.

TIOBE is weighted toward languages that have existed for a long time by virtue of counting lines written / skilled engineers etc. but the speed at which Rust is climbing that list is a better indicator. Also, a lot of the languages above it wouldn’t be appropriate for anything like a DE.

But you’re right, it’s hyped, I just think the hype is real.

This is a weird take. Rust is very popular and is the current heir apparent to C for systems level stuff. It’s a great choice to start a new DE/toolkit.

As for the rest, you’re right the end user doesn’t care about the language their graphical app is in, but the developers fielding their bug reports and making fixes/features sure do.
