Yeah, I’m much more worried about someone in my country spying on me then China, like what are they gonna do from the other side of the world?

Randall did the math on this one: https://what-if.xkcd.com/31/

He assumes 64 GB microsd cards, if you use 1 TB ones, you could send 16 times more.

Easiest and most secure way? Mail (or hand deliver) a flash drive. That’s how they transfer data between super computers and data centers. (AWS even has dedicated trucks to do it)

Hot take, C is better then C++. It really just has one unique footgun, pointers, which can be avoided most of the time. C++ has lots of (smart)pointer related footguns, each with their own rules.

pass otp. Works, more secure then SMS, open source.

Next DEFCON is in two months, can’t wait to see them get absolutely pwned.

Run the BIOS self tests.

Something’s definitely broken (TPM errors, self test errors, graphical artifacts), but I can’t tell what from the image. I would guess motherboard problems, or a subtly damaged CPU.

Could also be more then one problem in the case of over voltage (worst case consequence of PSU damage), or intermittent failure from under voltage (should be fixed with a new PSU).

This is actually how you should declare something that you will never change, but something might change externally, like an input pin or status register.

Writing to it might do something completely different or just crash, but you also don’t want the compiler getting creative with reads; You don’t want the compiler optimizing out a check for a button press because the “constant” value is never changed.
