Mercurial does have a few things going for it, though for most use-cases it's behind Git in almost all metrics.

I really do like the fact that it keeps a commit number counter, it's a lot easier to know if "commit 405572" is newer than "commit 405488" after all, instead of Git's "commit ea43f56" vs "commit ab446f1". (Though Git does have the describe format, which helps somewhat in this regard. E.g. "0.95b-4204-g1e97859fb" being the 4204th commit after tag 0.95b)

Seems to work with my personal setup at least, with two libraries - the default on ~/.local/share/steam, and one on /mnt/storage/steam - and Stardew Valley installed in the secondary storage library

There's a bunch of extensions that allow you to switch user-agent easily, I personally use this one, it includes a list of known strings to choose between as well.

Well, the first tests for interconnected communication with WhatsApp were done with Matrix, so that's a safe bet.

Valve did purchase the for-profit MoltenVK layer and had it open-sourced under the Khronos umbrella, so they've already been happy to provide people a Vulkan-on-Metal solution for those who want to support Apple without an entirely separate rendering engine.

I've been personally using KDEs Itinerary app, but it might not be what you're looking for

Well, it also says 'Premium Attractant' on it, so I guess you might find yourself with healthy buff bucks either way.

Well, both SUSE and Fedora use BTRFS as the default file system, RHEL uses XFS, etc.

My personal tip to 'transform your planet surveys' is to use a USB dance pad. It leaves your hands free to use a laptop, drink tea, play on a Switch/Deck, etc - so you can do something interesting during.

With my usual metric of game enjoyment - hours of interesting playtime divided by price in $ - Star Citizen actually does rather well, for a $45 entry it's definitely generated way more hours of actual fun with friends than most $60+ games we've bought.
It's definitely also generated lots of frustrating hours, but that's rang true for said $60+ games as well. I really wish there were more other games which do some of what it attempts.

ED was fun, but me and every one of my friends who're into space stuff have all individually burnt out on that game due to the frankly insulting level of grind.
NMS turns out to simply not be the gameplay we're after, so I have even less playtime in that than ED.
So far, Space Engineers and Avorion have been doing the best in that regard, still hosting a 24/7 Avorion galaxy for us in fact.

X4 has been collecting plenty of hours of playtime for me as well, but it's lack of any kind of meaningful multiplayer with friends does lessen the enjoyment somewhat.

We're moving towards more btrfs - or at least LVM+ where there's no btrfs support - on as much of our server fleet as we can, since the lack of snapshotting on the other filesystems is making consistent backups way too expensive resource- and time-wise.
With LVM it's at least possible to take a block-level snapshot - which is really inefficient compared to a file-level snapshot, but it at least provides a stable point for backups to run from, without having to pause all writes during the backup or risk running out a sliding window if allowing writes to continue.

For a home user (especially one who's not as well versed in Linux or don't have tinkering time), I'd personally suggest either ext4 - since it's been the default for a while and therefore often what's assumed in guides, or btrfs where distros include it as a default option - since they should be configured with snapshots out of the box in that case, which make it much harder for the system to break due to things like unexpected shutdowns while running updates.

I'd personally stay away from ZFS for any important data storage on home computers, since it's officially not supported, and basically guaranteed never to be either due to licensing. It can remain a reasonable option if you have the know-how - or at least the tinkering time to gain said know-how, but it's probably going to be suboptimal for desktop usage regardless.

We're in the end times now.
