Long enough that the "Mac" line ending (CR only, which was also the TRS-80 line ending before it) has been obsolete for almost two decades. I'm certainly not going to install Windows 10 for it.
I don't know what color your glasses are, but the only "P-code/JIT technologies" that I'm aware of using ARM would be Android. And in that case, it would still take a lot of effort to port the whole system. The system is more than just the apps.
There's a lot more to ARM's market than things that run a Linux kernel, such as the entire Cortex M line. And those already tend to be fragmented by vendor because even with the same core, each vendor has its own flavor of peripheral units. In these applications, C compilers are important, and almost never is binary compatibility important. In this market, ARM has competition with other architectures such as AVR, PIC, and MSP430, but with the technical superiority of being 32-bit. (Yes, I know about PIC32, which is really MIPS, the "other other" 32-bit architecture.) I'm sure ARM isn't too happy about another 32-bit competitor with an architecture that doesn't require a license to use its instruction set.
Look closely at the county roads in Oklahoma sometime. There is a grid numbering system for those roads, and most of them are aligned with the property block system. I'm sure this is the result of various factors, such as being mostly plains, and being settled in a short time period with a land rush.
If only Apple had kept it for a year longer, we would have had a 17" with USB 3.0. I'm still using mine right now, and I have one stashed away, along with an older 17" model. I think that my biggest long-term problem is going to be power supplies, thanks to wear problems at the wire ends and embrittlement of the crappy insulation on the power cords.
I'll be holding out for a Dell Precision, some of them seem to work well for Hackintosh, or I would get a Linux version. Meanwhile, my 17" still marches on. I just ordered replacement screws for the bottom plate, and last night a random CD cleaner disc restored its ability to play DVDs (and probably burn them as well).
A hotel room is likely to have random cards for room service, and you can probably find a newspaper. You can also use a suitcase; even the softest of suitcases aren't likely to block the ports. This is a problem that I learned how to work around at least ten years ago, back in the era of the Aluminum case design, of which I had three. It was very nice looking, but crappy in so many ways, the cooling being just one of them. Unibody was an amazing improvement.
Or even pictures of transportation in India, I would presume. Ah, India, the place where a bus with a seating capacity of 35 can have an accident with over 40 fatalities. (There were actually 85 or so riders. You can guess where they were "seated".)
I used to write code to talk to gas pumps 20 years ago, and they really aren't much different today, aside from having better screens and needing to deal with chip cards. (I have seen only a single station so far with what appeared to be chip-ready card readers! Isn't that cut-over only a year or two away? But there are restaurants that over two years later still have tape over the chip reader.)
First of all, the pump (the part that gives you fuel while measuring it) is completely separate from the terminal on top. They both talk to a computer in back over an RS-485 link. The computer in back, even if it's a crappy one from the pump manufacturer, takes payment information from the terminal (and commands from the POS inside the store), then enables the pump, possibly with a preset limit. When you hang up the hose, the computer sees that status in the pump, reads the dispensed amount, and finishes the transaction.
The back-end computer could certainly have bad programming. I once had to do a site visit for a beta site, and found out that the authorizer (the part that says "this card is okay, turn on the pump" and handles the billing) was saying yes to ANY card. Not my code, of course. Fortunately, people were using the membership card of the club store (they probably thought it would be automatically billed), which meant they could be tracked down if necessary.
One thing that could be done is to open up the pump, and flip its configuration switches to set it into a manual mode. That still won't stop the fuel counters inside the pumps, so it won't match inventory with the back room computer later on. But you have to open it up first. Not only is there a key to deal with, but these days there are tamper stickers on the door because so much inside can be fucked with, not just the pump.
Another thing that could be done is someone with inside knowledge of the system could create a management card that makes the computer give free gas. That would be noticed eventually too, but the big problem is you have to have access to the back end. This could possibly be done for a RFID keyfob, but that means you still need a way to get the keyfob ID into the system, and it would still be an inside job.
If the deed was done wirelessly, as implied, I'm going to guess that means that someone had a wireless connection like WiFi on the same network as the back-end computer, and it wasn't encrypted, etc. It could also be a keyfob or NFC, but other than that, I haven't heard of any kind of wireless technology that would need to go into the pump. It's always possible that there was some kind of stupid buffer overflow bug on something wireless.
As to what could have been done to shut it down, if the person at the store knew this was happening, um, yeah. Unless he called a manager who told him to not turn it off (fuel is a good way to get customers to buy your overpriced sodas and snacks), the E-Stop button would have been enough. An "out of order" sign would probably have worked too, simple psychology, nobody would have bothered to use the pump. It's also possible that the POS had a way to shut pumps off. And I wouldn't be surprised if nobody understood how to use such features.
Great. Now where do they get the food for these five or ten thousand super rich people? And if it depends on having other people do stuff, they have to feed those other people too. Even it was just one or two hundred "super rich" people, this is still a major logistics problem.
"But muh robots!" We're nowhere near the level of robotics they would need to live without filthy poor people, probably not within their lifetime, especially the kind of robots that can fix other robots. And you have to power the robots too... solar panels? They have a few decades lifetime before they have to be replaced, also battery storage would probably go bad first. Even our best-designed stuff has a hard time lasting more than a few decades even with maintenance.
There are just so many things about having a sustainable civilization that these people are apparently too clueless to understand just how hard it is to do, and instead they choose to gloss over the details for someone else to figure out.
Now if they just want to find a place they can escape to without civilization falling apart, that might be a tad easier. I have a feeling that they'll still have troubles living with each other in the long run, especially those with the more psychopathic tendencies.
These can still be found (10 years ago, you could get them for basically nothing and often came with keyboards)
The ones that came with keyboards and mice are nothing more than pin adapters for devices that can already speak both protocols. The ones you need for a Model M are the dongle-style adapters that have a PS/2 keyboard and mouse connector.
I forgot to mention that I also have two Northgate Omnikey keyboards of different layouts. The code ROM is even socketed in those, and I dumped them years ago. That's what I really want to put a USB micro into.
I have a decent stack of Model M keyboards that I acquired from thrift stores back in the late '90s, including a few space saver, but the main reason I don't use them is that I mostly type on a Mac, and I need the command key. USB isn't much of a problem because adapters are a thing. Is it possible to transplant individual keys like Cherry key mechanical keyboards? Someday I might want to try adding command keys and put in a microcontroller to make a USB version.
It's not much different at 110 volts, but this video was just the first good one I could find. This is why DC wiring only goes to 48 volts, because not much higher than that will arc. This is also why switches and relays have a lot lower DC ratings than AC ratings.
That's great, except that polarity doesn't matter for most things these days. That's why US plugs just have the neutral pin be slightly wider. It still allows non-polarized plugs in either orientation, while enforcing polarity for those things that need it, like lamps with screw-base bulbs. The typical dual outlet will let you plug in two wall-warts of almost any dimensions, except for those really annoying rare ones that are too wide in all four directions.
I still buy CDs... used. Luckily music these days is crap, so I'm not missing much. I can even get them for mere pennies at the right thrift stores if I'm lucky.
For four, 3He isn't even a first-generation fuel. It could take 10-20 years more after fusion has become useful. It will probably remain a meme at least until the end of the century. Anyone who says this is why we should go back to the moon is a TFM.

Or you could watch a video of a wind turbine being assembled. Start at 7:20 for the blades, in this case they are attached to the hub before being lifted.
And they are big, I passed a 3-blade convoy yesterday while driving in west Texas.
You think you're just joking.

So you're right, but for the wrong reason.

We can even let them pay extra to launch their Ark first. However, it seems Douglas Adams was wrong, and it was the "C Ark" that should go first.
That's great. Now what will I use for an option key?

You should have replaced them at a rate of once per week, for maximum mindscrew effect.

AC can be switched with very little arcing because of the zero-crossings. It's much easier to understand when you see it in action.
