  1. Minority Report on Tokyo Rail Billboards Scan Viewer's Age, Gender · · Score: 0, Offtopic

    Apparently, software automatically determining a person's age and gender when they're in public is nearly the same as using data gleaned from a few insane psychics to arrest people for future crimes.

    Except that they're completely different.

  2. Re:I must admit... on Wireless PCIe To Enable Remote Graphics Cards · · Score: 4, Insightful

    You're unlikely to be able to *alter* PCI traffic, though you could perhaps *insert* PCI traffic.

    Still, people figured out properly encrypting wireless links some time ago. Tempest is primarily interesting because the signals you're looking at are unintentional (and often unknown) side effects and they often deal with links that are impossible or unreasonable to encrypt.

  3. Aha! on NASA's Juno, Armored Tank Heading For Jupiter · · Score: 1

    I get it. The linked-to blog post (what is supposed to be TFA) is being supplied as an example of how to break every rule of English grammar, right? Likewise, the summary is an example of how to make a Slashdot summary by copying and pasting the first paragraph of TF"A".

  4. Re:Summary bad, but not as bad as you might think on NASA's Juno, Armored Tank Heading For Jupiter · · Score: 1

    Those are all low-accuracy numbers. Note that 0.8 m^2 could be described as "nearly a square meter" and "nearly 9 square feet". Equally, a third of an inch is "about 1 cm".

    That's also very common here.

  7. Re:Unit conversions on NASA's Juno, Armored Tank Heading For Jupiter · · Score: 1

    Your unit conversion is incorrect. 1 ft = 0.3048 m (exact).

  8. Re:Unit conversions on NASA's Juno, Armored Tank Heading For Jupiter · · Score: 5, Informative

    In English, the unit m^2 is written (and said) "square meter(s)" and the unit ft^2 is written "square foot [feet]".

    So, one square meter is 1 m^2, which is an area 1 m x 1 m = 3.28 ft x 3.28 ft = 10.8 ft^2, which is 10.8 square feet.

    There's an acceptable, albeit annoying, construction in English (or at least American English) that's completely different: "3 feet square" refers to an area 3 ft. x 3 ft., which is 9 ft^2.

  9. Re:I can see it now... on Electric Cars Won't Strain the Power Grid · · Score: 1

    For one, most of the available electric cars have gas engines (either because they're hybrids or to produce electricity when you run out of battery).

    For another, that sort of scenario happens on a yearly basis where I live, only with ice and snow.

    I don't know about the rest of the car, but it's the battery that has a 150k mile / 10-year warranty.

  11. Re:GM on Avoiding GM Foods? Monsanto Says You're Overly Fussy · · Score: 1

    Right -- how they actually keep the plant from producing viable seed matters. I mean, they're dicks regardless (although a lot of food plants are hybrids, where you can't use the seed produced anyway), but the Terminator gene either is dangerous or is perceived as dangerous. Not all methods of causing plants to produce sterile seed are as potentially-hazardous.

  12. Re:GM on Avoiding GM Foods? Monsanto Says You're Overly Fussy · · Score: 1

    To my knowledge, Monsanto hasn't actually used the Terminator gene in any of their products, they've just developed and patented it.

    Part of the scam is that they get you to download the remote-control software before they tell you they'll charge you. At that point, they can hold your computer hostage.

  17. Re:Some BIG assumptions there.... like bottled wat on Things You Drink Can Be Used To Track You · · Score: 1

    Congratulations for coming up with the same obvious problem everyone else did. Did you, by any chance, read the part of the paper where they discuss this problem and its ramifications and then test how well the isotope ratios in tap water function as a proxy for the isotope ratios in purchased bottled beverages?

  18. Re:Since when are oxygen and hydrogen ... on Things You Drink Can Be Used To Track You · · Score: 2, Interesting

    Nope. Different isotopes of the same element have the same chemistry, so chemical processes won't alter isotope ratios. This is an important feature of using isotopes as tracers, since generally the tracer elements will be subject to a lot of chemical processes -- like being absorbed into the body and incorporated in to hair.

    It turns out that TFA (which is just a bad summary of an actual paper) appears to have introduced the "minerals" bit. Minerals aren't involved; different water sources just have different hydrogen and oxygen isotope ratios.

  20. Re:Slightly misleading headline? on Daily Kos Pollster Made Up Numbers · · Score: 1

    No, that rule is straight out of style manuals. Proper modern style is to pluralize singular names (or other proper nouns) that end in "s" with "'s". Dropping the post-apostrophe "s" is common, but not proper modern style. However, there is an exception for ancient people whose names end in "s": they should always be pluralized without the post-apostrophe "s".

  21. Re:Rubbish on The Tuesday Birthday Problem · · Score: 1

    Incorrect! TH is only not an option if the *first* one is necessarily H. If you flip both coins and say "one of them is heads", you're not specifying which is heads.

    (On the other hand, if you flipped two coins, picked one arbitrarily, and said whether it was heads or tails, it wouldn't influence the probability of the other.)

  22. Re:Slightly misleading headline? on Daily Kos Pollster Made Up Numbers · · Score: 1

    Ancient people (or at least, ancient people of note) are pluralized without the "s" if their name already ends in an "s": so, Jesus' disciples, Moses' journey, or Socrates' principles (but Homer's Odyssey, not Homer').

    Yes, it's weird. No, I don't know why.

  23. Re:Stock price already increased on Tesla IPO Raises $226 Million · · Score: 2, Insightful

    Why would anyone want just another run of the mill "family car".

    Probably because they have a family and use a car for transportation?

  24. Re:Slightly misleading headline? on Daily Kos Pollster Made Up Numbers · · Score: 2, Informative

    Unless Kos is plural, since it's not the name of an ancient person, they'll need to add an apostrophe and an s. "Daily Kos's Pollster Made Up Numbers".

  25. Re:Rubbish on The Tuesday Birthday Problem · · Score: 1

    There are three options: HT, TH, and HH, each with equal probability. All three can be described as "one of them was heads".

    It's easier to visualize if you make them different coins. The stated problem is equivalent to, "I just tossed a quarter and a dime. One of them was heads; what is the probability the other was heads as well?"

    With no information, there are four equally-probable scenarios: QH/DH, QH/DT, QT/DH, QT/DT. The information provided (one of them was heads) eliminates the QT/DT possibility. So there are three equally-probable scenarios, only one of which fits the description of "the other is heads".
