Back in the '90s, I had a friend who wanted to emulate an 80386 with a old PC-XT (8088 processor + 500 MB of disk space). He abandoned the effort when he realized how slow it would be...
This sort of emulator is more a tour de force than a practical project.

I was in school before the IBM PC came out. Back then the school had a few big Control Data mainframes. They were 36-bit machines with a huge hard drive in a vat of oil. I wrote huge because of its physical size, not its capacity that was just a few megabytes. My friends told me that once they were messing around with the HD drivers and because of a bug they introduced, the drive started seeking back and forth so hard the oil started boiling. They shut it down before it was damaged and fixed the bug.
A few years after I was out of school, the AT was finally released. Those friends decided to write an emulator for the old CD mainframe. Their emulator was written in C and ran on a 8MHz 80826 in MS-DOS. They found some old programs they had written for the CD and were able run them on their emulator. The amusing thing was their emulator on the AT ran faster than the same programs did on the CD natively.

There is an old story (I first read it in a "History of Computing Conference" proceedings) about that program who put the computer on fire, in another (but not too different) way:
This program and its data was a little too big to fit in the machine. But the machine had a tape drive, which could address the tape block by block. So the programmers decided to swap out some of the data to tape, and bring it in when needed - sort of similar to a paging system, but realized in software.
When the program was run, it ended up with fetching the same block from the tape again and again, thousands of times. Even a highly polished magnetic head gives some friction, and friction causes heat. The more or less constant spinning back and forth of the same short piece of magnetic tape heated it so much that the tape caught fire, causing severe damage to the entire data room, destroying the tape station completely.
I have seen this incident referred to several places; at least one claimed that the tape was made from nitrocellulose, just like photographic film until the "safety film" arrived on the market in the 1950s. Nitrate film was still in use in professional environments in the late 50s. Maybe an old roll of nitate tape was laying around in this computer center several years later - the problem with nitrocellulose is that as it ages, it becomes gradually chemically unstable, and may actually explode. It makes the story of a devastating fire more probable.
I don't have any web reference to this story (yet it might be true...). If anyone has a link and more details, I'd be curious!

Now imagine Windows 10.
We'd probably need a new time measurement unit.

Windows 8 through Windows 10 with Fast Startup enabled should boot faster than all of the major Linux Desktop distributions.
Anyone complaining that a Desktop Linux distro is booting faster than a fresh Windows 10 installation is probably dual booting with the grub boot loader which will cause Windows 10 to boot with the legacy startup mode.
I can think of some other third-party software that could cause delay within the boot process. If your Antivirus software has implemented an ELAM that scans during the boot process. I guess other third-party device drivers could also influence the startup speed.

Don't forget the context. You think that mechanism will help when booting on an 8-bit microcontroller?

"How to Throw Up Better"
"How to Rock a Missing Tooth"
"Sinks are Just Strangely Shaped Toilets"
"Are Stigmata for Me?"
"Will Blinding Myself Make Me a Better Musician?"
"How to Fart Louder by Accident"
"Is Drinking Bleach REALLY that Dangerous?"
"How to Love Your Porn Addiction"
"Is She Still My Cousin if Our Parents are Divorced?"
"Is Self Absorption the Path to Enlightenment"

Speaking of such things, I just had one of those lovely "daddy can't crank the lawn mower" type moments trying to fix a dripping kitchen sink. Home Repairs Ain't Us.

Hmmm,
I'm disappointed. At first glance I thought this was a 15 step zebra logic puzzle.

I'd throw in a few intriguing titles, like "5 ways you can throw up better" :P

Microsoft has been warning us for months now that the "old" Skype would eventually stop working, as it's being phased out by that redesigned atrocity that looks more at home on Win 8/8.1/10 (although they back-ported it to Windows 7).
That version gets installed by default under C:\Program Files (x86)\Microsoft\Skype for Desktop and bears the version of 8.43.*. That one works fine. That's the newer one with the dumbed down UI.
The older version (the last to still have a semi-usable UI) is version 7.41.*. That version installs itself under C:\Program Files (x86)\Skype (both can run side-by-side), and has been sitting all week on my system with the spinning blue arrows icon, which indicates it's trying to connect. It's been stopped/restarted many times, the system has been rebooted - and I just found out it's doing the exact same thing on a secondary system of mine.
All public Skype status pages I could find all show everything as normal.
I'm guessing I'm not the only one, and that this actually means MS has finally pulled the plug on it...
[Edit]
I see it's being called "Skype classic", and was actually supposed to get killed last year on November 1st. Somehow mine kept chugging along until early this week...

Also here, still using it. This even though MS is able to make it worse and worse. Don't know a better alternative.

We're using Zoom. So far so good, though it creaks a bit when there are over 6 people with video

Thank you very much for this. I will have a look for it.

A corporate customer has started using this. Seems to be very hit and miss. Have several staff who can see the other end but have no sound and can't send video. Camera and microphone work in other applications though.

I went through this decades ago with all the various chat apps. I got tired of switching to the flavor of the week and settled on Skype when it got Microsoft's backing.

Well, the old skype tries to bind/listen on port 80 - if the new skype is running in the background, and has that port already, yer not gonna connect. Maybe. I think.

That's an interesting theory, but I've had both set up side-by-side for a few months now, and it's not until this week that the older Skype has gotten itself stuck.
