In the US, HIPAA grants you the right to access your own health information [0]. I recommend asking providers to burn the DICOMs to a DVD (or send your images to you via an online portal, if they and you prefer) whenever you have medical imaging done.
For anyone wanting a better image of the "Modern model of the Lehmer Bicycle Chain Sieve" than what is embedded in TFA, it can be seen on page #4 of the Spring 1983 Computer Museum report (which is also a PDF):

Cool project! I'm very interested in accurate preservation of the behavior of these old systems (chip decapping and scanning, FPGA reimplementation, accuracy-focused emulators) and using Ghidra to reverse engineer old games, especially on the 6502 and m68k architectures. Just an enthusiastic spectator at this point, but I hope to contribute something to the field eventually.
A sidenote: the action at 0:19 in the 50x-speed demo is intriguing. I've played many hours of Super Mario Brothers and watched various tool-assisted speedruns of it, but I don't recall seeing a Goomba reverse direction like that instead of just plowing into Mario. Is that a game glitch that you intended to show off with your recorded keyboard inputs? I haven't played in a long time, so I also wouldn't be surprised to hear that such behavior is common. I didn't find an obvious reference to it in the TAS info here [0].
Edit: there is precedent for that Goomba behavior [1].
I think that goomba bumped into the squished goomba Mario had just squished. Mario was just a bit to the left so the flat goombas hit box stuck out to the right a bit and the other goomba hit it.
I was researching the Armatron last weekend and was surprised to learn then about the single-motor operation. It's quite a complex system of linkages and transmissions [0] to enable the six degrees of freedom. I suppose that explains why the toy is so noisy. I had no idea that was how it worked, must not have taken mine apart when it broke or I outgrew it or whatever happened.
It also highlights an interesting change in engineering and product development that has happoned in my lifetime.
It used to be, when this Armatron was made, electronics and computers were magic and mechanical engineering, real complicated kind of mechanical stuff, was common and the slillset to do it was similarly common. In that world it makes sense to have the whole robot arm powered by one motor that constantly spins, with mechanical clutches and linkages deciding what moves when. That's because electronics and mechatronics like motors and encoders were still expensive and new.
Now its the opposite. In general, if given the choice between a complicated mechanical solution and a "simple" electronic/computer solution we choose that. Simple is in quoted because modern electronics and computers are far from simple. The manufacturing of a modern semiconductor rivals the Manhattan project. But is seems simple because we can just buy it at best buy and program it to do things. You can easily find lots of engineers to do something with code or an arduino, but finding someone who can design a fly ball governer, or even know what that is and why it matters, is rare.
Now days there are tons of cheap robot arms that have a servo motor for each joint, because servos are cheap and complex mechanics are not.

Servo motors aren't cheap at all.
Encoders aren't cheap either, in what universe do you live? The RC toys don't count by the way, because the cheap RC servos are terrible.
A fly ball governer? Is this some kind of joke? How are you going to operate it in any orientation other than upright? Why would you even want to?
There are probably ways to build a control loop with discrete electronics components that is cheaper than a mechanical system like that. Heck, it is probably cheaper to build an entire CPU with discrete components and then program that.
The reason nobody knows this crap is because it is useless. Your pseudo nostalgia for an age that existed before your time is ridiculous.
> For example Target used to not include groceries until recently.
There was a span of time where many of them didn't, but I was surprised to learn recently that the first ever Target store included groceries. See this 1962-05-03 advertisement[0] for the grand opening.

For high aspect ratio debris, it's not clear whether the given size ranges refer to the long or short axis. I wonder how the Project West Ford[0] artificial ionosphere needles contribute to these estimates. Apparently the remaining needles are mostly in clumps, so they might not be estimated at the individual level.
I hope we can develop a good method for space debris cleanup. It would be a shame if humanity ends up suffering from Kessler Syndrome[1]. Time to brush up on how to use a map and compass, I guess.
