Yes. Curiously, this would work even for a sufficiently intense beam of light. It is called "self-focusing", and has been proposed for use in an interstellar transport network.
Your vehicles would need not to be ripped apart to individual nucleons by the intensity of the beam.
I made a chess variant. Looking for play testers and feedback, particularly around the scoring system and clarity of the directions. It takes a minute to get your brain into reverse mode, but if you know and like chess, give it a try.
1) Scrape a news source and check how many times the bill is mentioned?
2) How many results on a search engine for the bill's title?
3) Train something similar to sentiment analysis model based on the text content of the bill. You'd need historical data for that but see options 1 and 2.
I think it would be fine for the library to have/be the 2ND FACTOR and the user would still need their password. Being at a physical location seems like a reasonable 2FA (more reasonable than a phone in these cases).
Could the library buy a few FIDO tokens, hot glue them into the backs of the computers, users add them as 2fa to their accounts and now the computer being wiped between users is no longer an obstacle?
- Users would only be able to use the exact same computer each time. If it’s out of order, too bad
- Users wouldn’t have unique tokens between each other, so there’s a risk of other library patrons shoulder surfing and then logging in with the same token after you
Look around the room for objects in sight. For each object, take its common name and count how many of the letters are "odd" letters acegikmoqsuwy, then mod 2. "Window" -> "wiow" -> 4 -> 0. Each word yields a single bit of very slow, pretty good entropy. Don't do this in the same room twice.
I suspect there's a strong bias in vowelCount % 2. A quick look at English 100 most common [1] has 1's at 73% and 0's at 27%. That would even out with longer words but I wonder how much. Maybe there's something else that's just as easy with less bias?
"The [turbines] affected remain in operation and are producing clean renewable energy. ... they will operate in automatic mode and are fundamentally capable of self-contained and independent regulation."
Sure, I'd hope for a heavily decentralized system to have some capability of autonomous operation. But in the medium and long term, it can't be good to not be able to remotely monitor for failures requiring manual intervention or on-site mechanical servicing.
The problem is once again our godawful prior government. Many tens of thousands of jobs in the wind industry have vanished over the last years [1] because the Conservatives oppose renewable power and impeded it wherever possible - if it is because of corruption, incompetence, fear of the far-right that outright demonizes anything not fossil or nuclear I don't know. In any case, we simply don't have the staff to visit literally thousands of wind turbines, a lot of which are actually offshore, simply to replace routers.
