  1. Because of the inputs ... on Power Companies Brace For Solar Storms · · Score: 2

    EM shielding won't help as it's not that the transformers themselves are directly affected ...

    The long power lines act as antenna, so it comes in as a surge in the normal input (or feedback from the output). I know it's not cost-effective to re-string every power line with something that's shielded (and that in turn could reduce the transmission ability, as they don't like making power cables more than about 5cm thick, so you minimize wind and ice loads).

    So, you'd have to put in some sort of a surge suppressor into the transformer ... which of course adds cost, but also gives you something else that can go wrong ... and for something that only happens once a decade, it might not be worth the potential for extra failures, the possible efficiency loss, etc.

    As for circuit breakers ... wasn't that what took out the whole north-east when Ohio lost a section of their grid?

  2. Why do you need 'mercenaries' ? on Get Cyber-Mercenaries Suggests Ex NSA, CIA Director · · Score: 2

    Currently, almost all IT support in the US government is contracted out ... so in a way, they're already hiring mercenaries, but I won't get into that bat.

    All you need to do is to have a pool of talent within the government that under normal situations does pentests at the request of government agencies / divisions / whatever, and in a situation when something big happens, they can be pulled from those assignments to actively attack something.

    This way, they get practice, we harden our systems, but it's not just some random hacker being contracted to make an attack ... they'd be regular government employees (although, likely contractors), who have had the necessary background checks, etc.

  9. HSPD-12 badges on Outgoing Federal CIO Warns of 'IT Cartel' In DC · · Score: 3, Informative

    So, the infamous 'HSPD-12 badge', aka, the 'CAC card' ...

    Supposedly they run $200 each. We all got bitched at for it ... have I *ever* used it to slot into a computer? Nope, because our network runs OSes that don't support the CAC functionality, and a lot of the folks on our machines aren't federal employees and remote users, so we'd have to have them run a background check (which we already do), then come in (from out of the country), finger print 'em, wait a month, then have them come back for a badge.

    And then we'd have to issue them CAC readers and force them to use Windows or some OS that can use the CAC readers (MacOS? nope).

    And if you loose the badge? Well, good luck on that one. Took me months to get a replacement. All the while, I couldn't enter any secured rooms, so I had to get issues a 'temporary' key card, and a 'temporary' badge ... which were EXACTLY like what we had before, only not at $200 a pop.

    And the temp badges? They have HUGE text on them for the things that matter -- expiration date (the HSPD12 badges run for 5 years, no matter the length of your contract), affiliation (just says 'Contractor' in tiny type), and has an indication of your security access more than just foreign national / US cltizen / civil servant (I'm guessing because then they'd have to issue new people badges 3-4 times as their various background checks get done).

    So ... more expensive, no new functionality that actually gets used ... and less secure, in that it's possible to enter the facility with an expired badge because the text is so tiny the guards can't read it, and they don't tie badge expiration to your contract, so a person with 1 year on their contract still gets issued a 5 year badge.

  10. Instruction after introduction... on How Education Is Changing Thanks To Khan Academy · · Score: 2

    I found it so much better than just listening to a teacher droning on for an hour or more, then having to go and read the book to figure out what they should've been explaining.

  12. Sales tax vs. Corporate taxes on Texas and Taxes: Is a Server a Business Presence? · · Score: 2

    The issue is the requirement to collect sales tax -- ie, the reason that Amazon keeps dropping affiliates in selected states.

    Basically, most states have laws that say that residents have to pay sales tax on everything they buy in the state. In my case, for Maryland, there's a line on the state income tax forms where I'm required to declare all purchases I purchased via mail-order where the company didn't already collect sales tax.

    Now, companes who have a presence in the state are required to collect sales tax in that state. So when I buy from Amazon, I'm required to pay it directly to the state, rather than Amazon collecting it at the time of sale, as they don't have a presence in Maryland.

    The problem is, sales taxes are *really* messy. What gets taxed? Food doesn't in Maryland ... but it does in DC if it's sold individually ready to eat. (which I don't think would count for mail order), so you have to know if a given item is or isn't taxed in each state. Then you also have cases where it's not only the state that has sales tax authority, but also the town or county ... so you might have an area that's differently taxed.

    And then you get into the message cases where the municipality doesn't match up with the postal designation, so you can't just rely on the zip code or city on the shipping address to determine taxing district.

    This has been a long-running issue since at least the late 1990s, when I first saw mention of attempts to come up with simpler taxing rules for mail order companies, but I don't know if anything's ever come out of those efforts.

    Um ... 'LASCO' is the coronograph package on SOHO.

    Since the launch of SDO, as AIA has a 12 second cadence for each of its EUV channels, EIT (the EUV full disk telescopes on SOHO) have been turned down to a minimal cadence (6hrs) so there's a long-term record from the same instrument, but there aren't any science planners for it anymore.

    So, to answer the question -- yes.

  17. movies == what the author meant? on Current Social Games Aren't Fun, Says MUD Co-Creator · · Score: 1

    I like movies 100 times more simply because I can SEE what the author meant.

    No, you're seeing the director's interpretation of what the author meant, as constrained by the producers, budget, ratings system, skill of the actors, etc.

    Even with the adaptation of comic books to movies (both visual mediums), some authors (eg, Alan Moore) have made comments on how they are effectively two different stories, as how the reader/viewer interacts with the medium is different. (pause the movie, and go check out what happened 5 minutes before to see how it relates to what just happened? Maybe in your own home, but in theatres, it means you have to watch it over and over again.)

    If you think that the movie is what the author intended, you're deluding yourself. The only time that *might* be true is when the movie came first, and the book was released second, or at the same time. (and not the 'book based on the movie', written by someone completely different). The only one that comes to mind where the movie and book are near equals was a TV series, not a movie -- Neverwhere, by Neil Gaiman

    You gotta love supreme court opinion that reference both Lord of the Flies:

    California's argument would fare better if there were a longstanding tradition in this country of specially restricting children's access to depictions of violence, but there is none. Certainly the books we give children to read--or read to them when they are younger--contain no shortage of gore. ... And Golding's Lord of the Flies recounts how a schoolboy called Piggy is savagely murdered by other children while marooned on an island.

    ...and 'Pick a Path' / 'Choose Your Own Adventure' type books:

    California claims that video games present special problems because they are "interactive," in that the player participates in the violent action on screen and determines its outcome. The latter feature is nothing new: Since at least the publication of The Adventures of You: Sugarcane Island in 1969, young readers of choose-your-own- adventure stories have been able to make decisions that determine the plot by following instructions about which page to turn to.

    And understands the difference between causation and correlation:

    The State's evidence is not compelling. California relies primarily on the research of Dr. Craig Anderson and a few other research psychologists whose studies purport to show a connection between exposure to violent video games and harmful effects on children. These studies have been rejected by every court to consider them,6 and with good reason: They do not prove that violent video games cause minors to act aggressively (which would at least be a beginning). Instead, "[n]early all of the research is based on correlation, not evidence of causation, and most of the studies suffer from significant, admitted flaws in methodology." [] They show at best some correlation between exposure to violent entertainment and minuscule real-world effects, such as children's feeling more aggressive or making louder noises in the few minutes after playing a violent game than after playing a nonviolent game.7

  20. Because you're comparing apples to oranges. on US Supreme Court: Video Games Qualify For First Amendment · · Score: 2

    First, there's two different issues here ... porn vs. violence. The courts have long established that porn is considered obscenity, and therefore, does not qualify under the First Amendment. They've never said the same thing about violence, which they're re-affirming here. (Although, I wasn't sure if they were saying that animal cruelty was or wasn't considered obscene)

    In the case of kids seeing R-rated movies -- it's not illegal. It's the movie producers an theatres acting as a group to set standards, but it's *not* the law.

    Likewise, the video game producers could voluntarily rate their games (and many do), but as people's experience may vary depending on how you play the game, they're notoriously difficult. And the ratings only serve as a recommendation system for the purchaser, unless the retailer makes it their policy to not sell items with stronger categories of markings to children. ...

    And oddly enough, for some of my formative years, I lived in Europe ... where they were much more accepting of the naked human body (not porn, just nakedness), but that violence was to be avoided. The A-Team was considered violent, but there was nothing wrong with naked people in toilet paper commercials.

    Also, it seems very unlikely to me that we might experience another global cooling period due to this weakened sunspot cycle, but it shows you that there are very sensitive effects going on here that are very difficult to predict -- and let me take this chance here to say that no, the Sun is not responsible for global warming, as has been shown fairly conclusively. It can mildly amplify or suppress such things, but is not the main driver of it. If it were, we'd see very strong correlations between the climate and solar activity on a decade-by-decade basis (or even shorter as sunspots form and dissipate over the course of days and weeks). We don't, and therefore the Sun is not the culprit.
