Since a QR code can contain an image file, and the image file can clearly be of a QR code, this is totally doable.

The real bonus would be for the image encoded, to be the same the final product QR code. That requires a special kind of collision.

Link to an image file, or the file itself?

If the code contains an image file in itself, I doubt the resulting image can be bigger than the code itself, even if the file is compressed. And some of the data will be used on compression and encoding, so a bit smaller. That is, a 16x16 code contains 256 dots. I think an image contained within it (if black and white) would have to have fewer than 256 pixels. Much fewer, if colors are used.

So you could probably stash a QR code in a QR code, but not infinitely and not recursively.

If it was only links to files on the internet though, then of course, it can link to anything.

I'm in charge of setting up my dad's work laptop, and it's a Thinkpad, with the characteristic red nub in the center, right? I used it, and I realized: it doesn't have a click feature. Isn't this thing supposed to replace a mouse/touchpad? How am I supposed to use this laptop one-handed with this like I can with either of those? All I'm left with is an awkward joystick.

Edit: The Fn button is where the Ctrl button should be. Why? I go to copy and paste (Ctrl+C, Ctrl+V), and I end up pressing Fn. What is this shit?

There should be 2-3 wide buttons underneath the spacebar, for use with your thumb.

Thinkpads are fine machines on my experience. And that clitmouse have seen virtually zero use in my case but it does have some advantages, like smooth, stable and solid movement if somewhat slow.

Mousenubs are neat.  I got pretty good at one back in the day.

I'm also backing up the files from the old work laptop, and I noticed that it's only used 60 GB out of 1 TB. How in the fuck is that even possible? My system drive uses 202 GB. Granted, 90 gigs of those are temporary files and Onedrive, but even with that in mind, it's still occupying 110 GB. Hell kind of optimization has my dad been doing? Install fuck-all programs, remove cache daily?

I'm not sure how an office machine doesn't get hopelessly bloated. I was expecting 200 GB of random crap strewn across the Downloads, Documents, Videos, Pictures and Music folders, but it's only, like, 3 GB total. Great disk space optimization, but it's kinda misplaced. He has an entire terabyte at his disposal, and he chooses to use 6% of it.

Also, if I replace the HDD in there with an SSD, I'm going to have... 8 drives total. It's really shaping up to be a personal army of drives. Should probably get one of those drive docking stations to make use of them, else they'd just be wasted potential.

Got into some casual mining recently due to a friend talking it up. Made sense, got a pretty good GPU for it, and with some fiddling with undervolting I can keep it running cool and quiet most of the time. So any time I'm not really using the PC I can leave it mining in the background. Worked good for like a week, made some 20$ in theory then something went fubar I guess and my GPU settings no longer work like they used to. No clue what changed with the whole setup but I am no longer able to run the thing at a decent 64-ish degrees and it instead rockets up to 75+ regardless of what I fiddle with in the settings.
Now, I'm not stranger to the arcane ways of shit not working as it should when it comes to electronics, but that usually happens after some change in the system fucks with something. Right now, I'm trying to figure out what the hell could've went wrong to cause this because I installed or changed literally nothing in the two days it went from being fine to being fucked.

Drivers update? Some change on the season on your country or ac on the room?

QR can be quite huge. The largest is a 177x177 matrix, called QR version 40.  It can encode up to 1.8kb.

A well compressed PNG image, with a decent amount of redundant pattern inside, at 1bpp, could easily be encoded inside that amount, that translates to an image that can have that many pixels (thanks to the heavy compression, due to the high repetition).

Again, the magic would have to be finding a collision domain, where the encoded data, corresponds directly with the resulting QR Code, such that the image data is exactly manifest as the QR code. Such a collision is ***NOT*** guaranteed.

However, getting the QR code to contain an image of the requisite size, that is also a QR code, is doable.
