Except he's enabled WEP because it's "more convenient" for him. It's still a strong signal that he doesn't want outsiders on the network.

A better door analogy is replacing the deadbolt with a slightly crappier one that unlocks whenever you're in bluetooth range (for "convenience"). Just because the system is "easily broken into" doesn't mean that you're not "breaking and entering" when you break the security and enter the house.


The number of shares in an option grant is not necessarily the number of shares in a stock grant. You're assuming the choice is "5,000 options [for a single share]" or "5,000 shares." That's ridiculous. Clearly the shares are worth strictly more. But that's (typically) not the comparison.


A capacitor meter to test capacitors that are soldered onto an PCB?



That's, uh, not a checkmate. Kxb1


Oh whoops, I had the orientation of the board upside down haha. My mistake.


This is crap.

1e: this is undefined behavior (-Wsequence-point) x can be literally anything.

3. a typical mistake that the compiler both warns about and that anyone who has taken a course on C should be able to immediately recognize

bonus 1. void main(int)???


Question 1 asks about syntax. The behavior of the code is irrelevant.


Except for the the fact that the author writes: "for bonus points, if x is 1 before 1e, what is x after that line?"


Then wouldn't an answer like "x could be anything because of undefined behavior" be correct?

This test is indeed quite evil, especially considering it was for freshman students. I have to admit, though, that the bonus question was great.



a complexity theory error: "Just as you can reduce all NP hard problems to 3-SAT..."

you can reduce all NP problems to 3-SAT because 3-SAT is NP complete. you cannot reduce all NP hard problems to 3-SAT. for example, all problems in NP reduce to SUCCINCT-SAT, an NEXP-complete (and therefore NP-hard) set. good luck reducing SUCCINCT-SAT to 3-SAT (despite how little progress in separation of classes we've made, the time hierarchy theorem still indicates this is impossible)


great response! NP-problem discussions make me happy. for those not understanding a word: http://en.wikipedia.org/wiki/Boolean_satisfiability_problem#...


SimTower was /actually/ just built around an elevator simulator. "You guessed right," she said. "Sim Tower was built around a real elevator simulation program we bought from a Japanese guy." http://www.gamasutra.com/view/feature/2150/the_designers_not...



I don't understand why there is so much xenophobia about this exploit. A government backdoor would be far more capable and sophisticated than this. Occam's razor applies here: an suid debug binary was left in the production image by accident.


Because "China". :)

Anyone who thinks the Chinese government had anything to do with this is just an idiot.
