I don't know why PIEBALD doesn't want to learn from YouTube but I can tell you my reason: because I'm slow. I like to learn in my own pace turning pages one by one, and sometimes going back on a topic and reading it again. This doesn't happen when a guy fast-talks at me. Just give me an old fashioned text and let me dig through it in my own turtle-like speed.

Myself I prefer reading. But I am a fast reader.
But videos seem the rage. A while ago I attempted to start learning javascript via a video course. Obviously for beginners. He spent about 15 minutes explaining what a variable was. So useless for me.

Sounds like magic, I am wondering how big a number can be tested with the regex hmmm....

That, I assume, depends on the limitations of the parser. If the parser is written in C or C++, and they use size_t for counting, that could allow finding all primes until at least 65,5352 = 4294836225.
This algorithm is extremely inefficient - O(n2) for each 'n', or O(n3) for all primes less than n. You will run out of time well before you run out of primes.

Yes, but Mersenne primes have special formats (in base 2). It's not as if we know all the primes up to 282,589,933 - 1.

This is not a problem of mine, but of a friend who call me every time there is some trouble with his computers. I will visit him next weekend and need some good hints for the problem investigation.
His newest PC, a small cigar box thing, is between 1 and 2 years old, and should be quite modern. (Sorry, I don't have the brand or model at hand.) He is running Windows 10.
For a couple of days, the Start Menu has been popping up, and then disappearing, at irregular intervals of a few seconds, as if he were randomly hitting Ctrl-Esc every few seconds. Intervals are not fixed, neither between popups nor how long the menu is displayed. When it pops up, it steals the focus, making it impossible to get any work done. If he opens the Start Menu explicitly (by clicking the Windows icon), and it takes him a few seconds to find the right entry, the menu closes.
It sounds very much like a faulty keyboard. But the thing is that if he disconnects his wireless keyboard completely, by unplugging the dongle, the problem remains. The mouse uses the same dongle, and is disconnected as well. I strongly suspect a hardware fault within the cigar box, but I think it strange that a hardware fault has this single
effect and no other visible signs.
He has tried to do a complete reinstall of Windows 10; the problem remains.
In between the Start Menu popups and closes, he has managed to start Notepad to do some simple typing. There is no sign of "ghost characters" that he didn't type himself. There doesn't appear to be noise on the keyboard input line, unless there is some filtering of keyboard input to Notepad that isn't applied to the opening of the Start Menu.
When I visit him next weekend, what should I do to try to identify and isolate the problem?
(I am not a hardware man, so I have no fancy electronic test equipment!)
