I agree, Veritasium, Vsauce, SmarterEveryDay and Sabine Hossenfelder are prime examples of channels that make YouTube worth using even if you wouldn't like all the ads and random stuff.

@talosgak1236 Speak for yourself. I've learned a lot from many videos I watch. However, that requires active watching, not thinking about other things at the same time.

The search for Mersenne primes (the program called prime95) has provided us the best known software to verify your system is stable. The software has "torture test" mode which re-computes some of the really hard tests with known results and if your system fails to compute the exact same result, there's something wrong with it. The interesting part is that a single bit error in any part of your system will result in incorrect result and the computation can be configured to require as much RAM as you wish. As a result, if you configure it to use all the RAM in the system and it can successfully compute many numbers, your system is running bit perfect. And if you test it with any overclocked system, the changes are that the system is not bit perfect. Overclockers call system "prime-stable" when it can run prime95 torture test for 24 hours without any errors. So you could argue that this weird mathematical process has already provided us the best known method for verifying computer hardware correctness! As a bonus, the software is so well optimized that it can typically generate maximum heat for the CPU thanks to running on all parts of the CPU in parallel. As a result, it will also test the cooling solution of your computer in addition to checking it's running bit perfect.
