Clearly we need blockchain to solve this, not AI! /s

Eh, I think part of it is just making a more clickbaity title.

Maybe he's confusing it with the other post? https://subseacables.blogspot.com/2024/10/facebooks-semi-sec...

Huh, good to know. I guess the only other downside is actually making the compiler do the bswap depending on the language. Eg C has some weird compiler specific builtin keywords vs zig has a nice packed struct that does it for you.

I know that's the standard but for all private projects I always write little endian so I can sleep soundly at night knowing I've saved precious picoseconds not flipping to cpu order.

+1 there are many pain points, probably for historic reasons. *nix almost always comes with the source, so binary only debugging is never a priority.

Technically. I'm saying there's a huge difference between what a layman might read "large org conspires to spy" and a possible dull reality of "some engineer neglects to remove convenience feature".

Basically there's a master key that allows reading blocks that are supposed to be unreadable.

Hard to prove "on purpose" either way, my guess it was for debugging.

That's my understanding as well. Voltages are relative, you are free to choose a "ground" and work with negatives or not if you want.

We'll soon need reinforced, precision machined, well oiled cubes for robot tournaments ^^;

For usermode fuzzing it's pretty nice and easy to get running, but for more advanced cases I ended up using the underlying unicorn-afl directly. IIRC it wasn't loading some ELF correctly (this was some years ago).

Having owned a few old motorcycles, the stock bulbs are terrible, you can barely see anything at night. LED aftermarket parts have been decent in my exp. That being said some cars are too bright but surely you could dim them a bit.

Clearly removing all plants gets rid of all weeds as well. I see no problems here.

The funny thing is IDA added an x64 decompiler for the free version right after the post. The piracy could have been avoided if it wasn't for the timing.

I think vagueness is kindof ok in math/physics questions - if you think about it there's usually and interpretation that makes more sense, but I doubt most of them are made that way on purpose.

Where I really hate to see it is humanities e.g. psychology tests/surveys - if after reading a question I immediately think of 3 different interpretations I just think it's a bad test. And if I spend any more time thinking about it I get almost nowhere.
