The compiler doesn't always know how big that free space is, because there's no type or size associated with it. It's possible in some cases to do bounds-checking, but not in many others. It's a fundamental difficulty with the language, and it's impossible for the compiler to check all those bounds without help from the language or the programmer.

That's not quite true: the compiler could arrange to pass around more than just the raw pointer (or in extremis could maintain a duplicate of the malloc table and work out the bounds given the pointer), but the performance hit would be considerably more than for direct checking.

"This is /. after all" was intended to refer to "I admit not having read", but now that you point it out I suppose it is fair to say that most of the stuff posted is clickbait. I couldn't say in general whether that's because it's submitted by the authors of the links or because submitters can't be bothered to track back to the less sensational source.

I admit not having read the clickbait (this is /. after all), but I presume that the real story behind it is that an experiment to measure the muon magnetic moment has recently moved from Brookhaven to Fermilab to get access to more energetic muons. They're hoping to start measuring data in 2.5 years.

Well, if we use the same kind of accounting principles that were used to try to extradite Gary McKinnon, this is an article about an intelligence agency causing potentially billions of pounds/dollars/euros of damage to computers, 99%+ of which were not "legitimate targets" for a black bag job. It may not be a surprise, but it's still rather embarrassing.

But he's not charged with money laundering. He's charged with conspiracy to launder money. If dirty money comes in and clean money comes out then money laundering has occurred, whether or not some of the intermediate steps involved the exchange of non-monetary assets. So "I was only involved in transactions involving the exchange of non-monetary assets" is irrelevant: what matters is a) whether they were part of a larger chain of transactions to launder money; b) whether he was aware of that larger chain.
