That depends on what you want to do. For my part, I'm very content with having lots of power and minimal network(s). Actually, I need the internet mostly to bug you guys here.

In that calse I can reveal that I actually live very well with the good old VT100 at 9800 or 19200 bits/sec.

Brings back memories! My university years were spent on a PDP-10, which I still remember fondly. When the VT100s (or maybe one of their predecessors) arrived, it was like a new world opened up. Then the DECWriters only had to be used to get hard copies.

The Zwölf, my modernized version of the old Elf on Ebay is still stuck with a serial terminal. It does not even have a serial port. It does RS232 in software on two bit banged general I/O pins like a microcontroller. 19.2 kbit/sec is not so bad for that. Of course I have no real VT100. Terminal emulation on an elderly PC will have to do.

I remember looking at an earlier post of yours and being quite impressed with its character display, which was what, 3x5?
I'm thankful to have much more memory than in the past. Having to go to disk destroys performance to the point where some things can't be done. But now, processors are so much faster that people write crap that would have been a non-starter 20 years ago.

Take another look here[^]. It's in the gallery, along with many others.

How about 16 mb on the little Elf? Would that be enough? If not, I can extend that to almost any size by making the page registers a bit wider. Paged memory is nothing new, but the processor allows me to do the page switching in the calling procedure. The processor does not notice anything and the settings of the page registers end up on the stack, along with the return address. I can call routines anywhere at any time without knots. The only difference now is that I must use 24 bit addresses instead of 16 bit addresses. Why did nobody ever think of that in all these years?

The product I worked on for many years had 16MB and 24-bit addressing, which was adequate for a long time. But my C++ static analysis tool uses far more (over 300MB for a decent sized code base), so it would have to go to disk, and the compiler would have to do page switching before procedure calls.
16MB on an Elf! No hobbyist could have afforded that much memory back then and would probably have looked at you like you were from Mars if you said that it would happen one day.

I know. Had to sell my childhood to scrape together enough $$$ to buy a 4k RAM board. One like this one here[^]. One of the RAMs had an error, so I had to raid a Radio Shack to get a good 2101 SRAM. 400 ns access time. Still works, so it was a good investment.

Finally decided to add the Community Toolkit to my UWP app to get a Grid splitter.
That led to trying the "new" Windows XAML UI controls. (It's uneasy when they "thank you" for installing the new controls).
This required a newer Windows 10 SDK.
Adding that via the Visual Studio Installer first required an upgrade of the installer. This in effect installed I believe a new version of Visual Studio.
Started out reaaal slow, but with a restart or two everything seems ok ... and I can now see little rounded corners on TextBlocks.

I'm glad to see, after all of that, that your system's caught up to CSS3.

It's not that you couldn't do it (you'd use a border with rounded corners). It just happens to be one thing I noticed of the newer Windows "style".
Did you notice the new VS uses color icons in the source XAML now to show you what colors are specified; or is that another, old CSS thing?

That would be a VS studio thing - how it displays its stuff (in a way, just like any other encoding such as is done with text).
CSS, itself, is just an HTML attribute (either as style or class). If some editor wished to parse it and display those types as colors I guess it could.

This is way beyond my professional field. I have no clue at all, that is why I ask:
This corona vaccine must be stored at -70C or lower. The common technology for a fridge, a freezer or a heat pump, is to spray some cooling liquid through a nozzle so that it goes from a liquid to a gas - 'evaporates', if you like. This state transition draw a lot of energy from the environment. But there is a limit to that. If the evaporated gas never goes below, say, -35C, then the environment will not be drawn below that.
So how to you, artificially, create extremely low temperatures? I guess that there exist (most likely extremely expensive) fluids that, by evaporation, can go several degrees below what is used in our deep freezers. But 'several degrees' is not enough when you need forty to fifty of those degrees... The learning I did in my school days simply doesn't cut it!
How to they create super-cold temperatures nowadays? I'd be satisfied with appropriate links to replace explanations. Even suggestions for focused google search terms would be nice!

Hmmm,
I honestly don't know how the medical profession would do this. But Derek Muller has a video where he uses a helium-based cryocooler to make Liquid Nitrogen in his living room.

Ultra Low temp freezers like the ones they need for the mRNA vaccines are just like normal freezers, except beefed up a fair bit. Take a peek at How does an Ultrafreezer work?[^] for a super quick overview.
Or they could just move production to Canada and they'd be fine.

Well, the snow and slush today were magnificent. And the coffee, were the cafes open, was probably excellent. I especially enjoyed the wonderful surprise of stepping on what looks like snow to find it's actually a foot of salty water covered in a thin sheen of snow.

Same principal. But when the temperature difference is large it has to be done in several steps using different gases at different pressures.
