Someone who deliberately cuts off their own legs with a chainsaw don't get sympathy. So why should addicts?

I imagine someone who would do that on purpose must be suffering from some serious mental problem, or must have been blackmailed or under some kind of duress. Certainly they do deserve sympathy and help.

What "undefined" means here for most compilers is that it will make the best attempt it can under the C rules but the results may vary on different machines. Ie, it will use the underlying machine code for adding two registers, which may wrap around or possibly saturate instead, and the machine may not even be using tw's complement.

No, that would be implementation defined behavior.

While one might argue that forbidding them from donating is unfair, or has a basis in incorrect assumptions, let us not pretend that allowing gay men to donate blood would make a significant difference if a shortage exists. What percentage of the population is a homosexual male? Perhaps 3%?

Any flock of flying robots, autonomous or not, over my head or my property will encounter bags of nails, wires and other terrible obstacles designed to swat them.

Remember kids, what goes up must come down... in unrelated news, people who oppose drones can be recognized by the nails, wires, and other 'terrible obstacles' that embedded in their face.

They should take this site and give it a new name. Or get Malda to let them use "Chips & Dips".

Leave everything else intact, archives, user ID database, everything except the name.

Then use the Beta code and start a new site and give it the slashdot.org name, and they can have what they want without the embarrassment of having the current userbase escape from the basement or the attic and offend the sensibilities of the yuppies or hipsters or metrosexuals or whoever it is that they really want for an "audience"."

Not this compiler-inserted backdoor crap again... Look, an assembler could insert a backdoor as well. And any of the developers could insert a backdoor. Did you read the entire source code? Even if you did, do you think you could find a cleverly hidden backdoor?

Besides, all you need to do to get rid of the hidden compiler backdoor (assuming there is one) is write your own compiler, use it to compile the suspected compiler, then use the generated compiler to compile itself, and presto, the backdoor is gone. Writing an interpreter instead of a compiler is also an option. Since you only need to do this whole process once, your compiler doesn't need to do any smart optimization and it's acceptable for the whole process to take some time (a week? a month? who cares).

Most kids are going to have access to a normal computer anyway, which would include a monitor, keyboard, and mouse. They can use ssh access or some kind of remote desktop to control their RasPi. No extra support hardware required, apart from a power supply, a sd card (they're dirt cheap) and a UTP cable to connect it to a switch/router. Your 'well past $200' estimate is completely ridiculous.

Modern VMs already compile when you need a speed boost.

Did that really make a meaningful difference? I imagine the interrupt handlers would have very little code and would never ever result in pages getting swapped out.

Yeah it's all rather disappointing really, but at least we know that gains in processor speed won't some day break our crypto (assuming it has no other weaknesses).
