"120mm optical media" is better, because that's the official measurement, but it has its own problems. There's the "mini" form factor at 80mm and the credit card form factor as well, and those still qualify as CDs, DVDs, etc., even though they're not 120mm.
"Optical media whose most common form factor is a 120mm disc" fits, as does "CD-like media", but the former is wordy and the latter comes with the potential confusion that the others are CDs, when they're not. Which I admit to deliberately avoiding for precisely that reason.
If it's owned by a corporation, then fair use and/or non-commercial use may come into play, depending on local legislation. Basically, use it until you get told to stop. It's effectively free advertising until they take exception to you.
For a smaller creator, they're usually more receptive (and responsive) than a corporation, so consider asking permission.
You could go full Weird Al and ask permission of a corporation if you're that way out. But they're more likely to not respond or say no if they have no idea who you are.
Of course, a thing to watch out for is the unlikely occurrence of becoming famous while using that avatar. It can't be your brand because it's someone else's.
So, you might consider pulling a Ray Parker Jr. and (commission someone to) make something that's almost but not entirely unlike the artwork you're trying to use. That said, RPJ did get sued anyway. Maybe take it a couple more notches off similarity.
... oh and try to avoid using AI to clone something.
If the day ever comes that I end up in possession of a healthy late 20th century laptop, I'd genuinely consider putting FreeDOS on it. Not least because I threw away my customised MS-DOS 6.22 and Windows 3.11 floppies years ago (a regrettable decision).
For later hardware, I think I'll stick with Linux.
For a middle ground, I seem to remember Puppy Linux, which is designed to run on more limited hardware, runs most things as root. (Though maybe they've changed that in the intervening years. Correction welcome).
For a long while after the Iraq debacle, I was predicting that Iran would be next, and it just kept not happening.
I guess even the right-wingers of the time were too level-headed to want to open that can of worms.
Heck, even Trump didn't go there during his first term. I had accepted that I had been wrong.
So, of course, this time, the crazy old narcissist has gone and done it.
(This reads like I feel like I could have done something to prevent it. I know I couldn't, I'm just some random guy, but I still feel like I took my eye off the ball.)
The pedant in me cannot let slide that your title talks of compact discs but the image is of write-once blank DVDs.
But no, I don't use any form of 4.7" optical media very often. The last time I used the optical drive in this computer was to watch a DVD that I didn't want to go downstairs and watch on the TV. That must be a good few months ago now.
As to why I even have such a drive - long, boring story. I had assumed that if I ever had need of one, I'd just take the one out of my old PC. When that time came, the newer PC refused to boot with that drive installed. (Imagine, if you will, being in that situation, and the ensuing horror and frustration.)
It then made sense to buy a different one to troubleshoot and cover that potential need. And I haven't bothered to uninstall it after "testing".
It would be amusing if this actually got the powers that be to consider proportional representation. Better chance of having a say in government if the alternative parties start beating first-past-the-post. One voice that must be listened to is better than shouting impotently from the wrong side of the house.
I assume they're using (year - 2000) as the version number, which happens to match "last two digits" and will do until 2099. So any version of Minecraft released that year under the new system would be Minecraft 1002.x, not 2.x.
There's a Linux tool called cmp that compares two files byte for byte. On my distro it's part of the diffutils package which is required and installed by default.
Its better known sibling is diff which is used for finding differences between source code files, or any other text files for that matter.
You could build something fairly quickly that wrapped cmp and a list of files.
Alternatively you could look for a duplicate file detector, but then, those generally only pick up on the duplicates and won't show non-matching files. You'd be blind to the changed ones unless you already knew where they were supposed to be.
Also be aware that on modern filesystems, there's such a thing as a hard link where two or more filenames can point at the same data on the disk. Those two files will always compare as being the same because they literally are the same. And some filesystems can automatically de-duplicate by creating hard links between anything it detects as being identical.
You might be able to leverage that as well, depending on what you need.
Finally, many files have various dates and times associated with them, again depending on file system. The Linux stat command is aware of four of these: File birth (original creation), last access, last modification and last status change. Some or all of these may be combined depending on the underlying filesystem.
Actually, Minecraft 26 comes out this year. They dropped the "1." and bumped the sub-version from 21 to 26 to match the year. They've also changed the way the new second tier works to be related to the quarter-year.
26.1 is due next month.
So yeah, there'll never be a Minecraft 2.0. The versioning no longer allows for it.
(This doesn't rule out a game called "Minecraft II" with its own set of unrelated but identical version numbers. Minecraft II 36.1 drops in ten years. Maybe. But probably not.)
I'm not sure that's K&R style. In various places you have things where the thing that follows a for, while or if isn't indented, and as far as I'm aware, K&R indents religiously. K&R omits braces on single statements, sure, but that statement is nonetheless indented from the parent keyword.
e.g. you have things like:
while (condition)
statement;
and
for(x;y;z) {
if (condition) {
statement1;
statement2;
}
}
Which I'm pretty sure should be:
while (condition)
statement;
and
for(x;y;z) {
if (condition) {
statement1;
statement2;
}
}
respectively. The idea is that you can theoretically trace the keyword down to its closing brace, assuming there is one.
Rebooting is a good idea from time to time to ensure any new updates have taken fully and that old system drivers haven't lasted and continued to run.
For example, one time I installed an XOrg update but didn't reboot because my distro's updater didn't recommend it. And so I was very confused when I actually did reboot and graphics were borked. It took me a while to track down that the update - which I'd forgotten about - hadn't been compatible with my graphics driver and I'd been using the previous working version until then.
It's supposedly possible to restart / reload all software without rebooting, but it's a royal pain in the [proverbial] when it's deep in the system, and it's far easier to just reboot.
And if you're gonna reboot anyway, you could time that nicely for before you'd be about to stop using the computer for a while. Let it reboot first to make sure everything seems OK with any updates that might have been applied. When that works, you're at a fresh slate with no programs open, so you can then turn it off.
(And if it hasn't worked, you can roll back with something like Timeshift or whatever your distro provides, check that works and save the investigation for when you have time.)
Call me cynical, but I think you've put quotes around the wrong part of your title.
Try around "accidentally".
