  1. Re:Stuff on Researcher Exploits 18-Year-Old Design Flaw To Compromise X86 Chips · · Score: 2

    Really? All the articles I see say that the problem was a faulty lookup table. No one says the lookup table was subjected to a formal proof of correctness.

    Why is all the stuff broke? Why does all the stuff have holes in it? Why isn't there any stuff that isn't broke?

    Because it's too complicated. There are too many possible failure modes and many of them can't be seen without a large effort to see them. About the only thing that might eliminate the holes is formal proofs, but that requires not only a complete revamp of how we code but makes coding itself immensely more difficult.

    ARM processors from now on. All this stuff is broke.

    ARM processors are just as broke as everything else. There's just fewer people looking to uncover the holes.

    Differs from the US in that in, the US, the penny is a coin, not a monetary unit (the monetary unit is the cent--a pound is 100 pence, a penny is 1/100 of a pound, but a dollar is 100 cents and a cent is 1/100 of a dollar) and is pluralized as "pennies".

    How about Wozniak? Of course, he had the good luck to be partnered with somebody good at business, at least for a while.

  8. Re:Do you think it happens only in tech? on Tech's Enduring Great-Man Myth · · Score: 1

    That's mainly because the misplaced modifier in "it only happens in tech" doesn't confuse because it makes no sense to apply "only" to "happens" ("This is the only thing that happens in tech; nothing else does").

  9. Re:Do you think it happens only in tech? on Tech's Enduring Great-Man Myth · · Score: 1

    The person who needs to return to grammar school, it appears, is you. Adverbs can modify other adverbs (https://en.wikipedia.org/wiki/Adverb). Propoositional phrases can act as adverbs (http://www.chompchomp.com/terms/prepositionalphrase.htm). So it perfectly kosher for "only" to relate to "in tech", as it does in this sentence.

  10. Re:They'll do it wrong. Let's buy the rights. on Dungeons & Dragons Is Getting a Film Franchise · · Score: 1

    Note to the movie industry: Dungeons and Dragons is a rules framework upon which stories are built, not a story itself. Making a "D&D" movie is like basing a film off "Hoyle's Book of Games."

    That's exaggerating. D&D provides a fully worked-out setting that would work equally well for a movie, and even provides pre-made adventures to play. Granted, there are people who don't use the setting, and they're not likely to make a module into movie--though they may well use some the characters there. But there's still a lot more to work with to make a movie out of than there is in Hoyle's.

    EU so far does not have any dictatorships as members

    Hungary's getting pretty damn close. In fact, I'd say Hungary is closer to one than Turkey. Last election in Turkey, the ruling party didn't get a majority of the seats in parliament and had to form an alliance with a party it doesn't control. That's not something you generally see in a dictatorship.

  13. Re:50% is lost in AC to DC conversion? on Giving Up Alternating Current · · Score: 1

    In addition to inevitable losses in the machinery, any heat engine (which is what any fossil fuel or nuclear power plant is) generates usable power from the difference in temperature between your heat reservoir and your cold reservoir (where you dump your wate heat). This difference imposes a basic limit to how much heat you'll convert to usable work, that efficiency being greater with a greater temperature difference. This efficiency ceiling is known as the Carnot limit. The reminder of the heat generated must be lost as waste heat. For the average power plant, the Carnot limit is around 60% (the average car engine, which is also a Carnot heat engine, has a limit of about 25% to 30%). Other losses reduce the efficiency to about 40%, so he's actually about right here (he needs an education in electric circuit design, though; he doesn't understand AC to DC retification at all).

  15. Re:The Bottom Line on Behind the Microsoft Write-Off of Nokia · · Score: 2

    Umm, writing this off does not in anyway improve their bottom line.

    Actually, this is pretty common trick to improve the bottom line. It doesn't improve the bottom line in that quarter, of course, but the single huge writeoff concentrates all the losses in the one quarter, making all the other quarters look better. Management then passes off the one bad quarter as an anomaly.
