If you preorder, just 100 $/€ are taken from your credit card. The rest is booked shortly before the device gets shipped. So, your risk is 100$/€ if they went bankrupt before you get your device. I have seen worse, imho.

Today? It always has been like that. I remember the nineties popup ad banner days. Not much has changed.

Those where the good days. You always had fresh coffee when your computer was ready for work.

I use autologin too with disk encryption and i don’t see an issue. If you have the encryption password nothing can stop you anyway. And if you put your computer in any sleep mode you have to login after waking up.

RISC architecture is gonna change everything…

i for index or iteration. Using j, k, l… in loops signals (imho) that there is most likely an outer loop and the one using j, k, l are nested. x and y of course are carthesian coordinates . n is used as amount of substance in SI-unit-system, m is mass, maybe thats why it is used as amount of items in a set (Menge).

Programming computers have started to solve mathematical problems and math already used these symbols for centuries(?), so why you should change them? They are well established even in simple school mathematics. And at the end of the day a computer is nothing more than a calculator.
