  1. Solar isn't "there" on Solar Panel Breaks "Third of a Sun" Efficiency Barrier · · Score: 3, Informative

    Maybe not for you.

    Most states have more expensive electricity than $0.10/kWh.

    Also, most people who have solar go on a time-of-use rate where they can sell back power in the day when electricity is worth more and then buy it back at night when it is cheaper.

    My array will pay back in about 9 years. Less with the tax rebate. And it cost less than $1280/panel installed even before rebates.

    When did you measure the panel? Even at $0.10/kWh it should make a little bit more power than that during the summer. My panels are making about 800Wh a day a piece right now and the days are very short at the moment. They make nearly double this much during the summer months.

  2. except energy often costs more than $0.10/kWh on Solar Panel Breaks "Third of a Sun" Efficiency Barrier · · Score: 1

    I know a guy who got his energy for that price in Texas, but in California electricity costs more than that. Probably in Arizona too.

    More expensive electricity means your panels pay back more quickly.

    Also, over the period you own your panels, the price of electricity will almost certainly go up.

  3. or neither gets them on Valve: Linux Better Than Windows 8 for Gaming · · Score: 1

    You've created a false dichotomy. There are a lot more choices than Windows and Linux. Even if Windows fails (no evidence it will other than Gabe's wishful thinking) it doesn't mean Linux will then succeed. Developers might just go to all-console.

  4. Re:Grow up on Steve Jobs' Yacht Revealed · · Score: 1

    To me, the hull looks brutalist, I would just call the rest of it modernist (and since brutalist is modernist too, that makes the whole thing modernist I guess).

    Just as an aside, whenever I read someone saying something is Art Deco I just pretty much always substitute in Bauhaus. For some reason people seem to forget the ornamentation of Art Deco and just remember the shapes of the metal, glass and concrete.

  5. intellectual property is not free in the EU on Australians Urged To Spoof IP Addresses For Better Prices · · Score: 1

    It's insane. If they really had a common market for IP, then you could subscribe to (for example) the cheapest Premier League package of any country in the EU and watch it at your house. But you can't. It is priced country-by-country and the sellers do not compete across country lines.

    Same with downloadable music or games.

    It's surprising the EU isn't working to fix this.

  6. I can't even tell what you're saying. on PS3 Encryption Keys Leaked · · Score: 1

    If a console is capable of running unsigned content but as a rule it refuses to, then that's client side no matter how you slice it. Yet this is what you are suggesting they should have done.

    As to what they actually did, it's a financial issue not a technical one. If a console is fully functional with unsigned content, then developers will not pay to get their content signed. Since the console business works by getting license fees and the signing is what enforces this, this would mean it would be financially unviable to run make consoles.

    The key to making a console isn't really making it impossible to run pirated content. It's to make sure that it is hard enough to make full functionality unsigned games that developers don't feel they can try to go without paying you to get their games signed.

    Sony put restrictions on what PS3 linux code could do. But once hackers broke this and accessed full functionality, Sony had little choice from a financial perspective. They had to close the holes. Maybe removing PS3 linux was the only way to close the holes, I dunno.

    PS3 linux was crap, you could get a better linux machine for less money before PS3 linux was even removed from the machine. I find it really hard to draw a true link between being denied what PS3 linux offered and hacking the PS3. I far more think it's like you say, these people want to see nifty hardware.

  7. that only does anything in multicast transmission on Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra · · Score: 1

    Note the multiple deliveries in the butterfly network.

    It doesn't increase capacity for unicast case. And TCP is unicast.

  8. it does use more spectrum on Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra · · Score: 2, Insightful

    It's called forward error correction and it requires sending additional redundant data so you can solve for what is missing. Sending additional redundant data does use more spectrum for the same throughput, because you're sending more data. It may be worth it to avoid retransmissions when data is lost, but it definitely use using additional spectrum.

    This is nothing new, your computer uses FEC on its storage (HDD or SSD) and maybe even on its RAM (if it has ECC RAM).

  9. No, they don't all age the same. on Ask Slashdot: How Do SSDs Die? · · Score: 3, Informative

    It's statistical, not fixed rate. Some cells wear faster than others due to process variations, and the failures don't show up to you until there are uncorrectable errors. If one chip gets 150 errors spread out across the chip, and another gets 150 in critical positions (near to each other), then the latter one will show failures while the first one keeps going.

    So yeah, when one goes, you should replace them all. But they won't all go at once.

    Also note most people who have seen SSD failures have probably seen them fail due to software bugs in their controllers, not inherent inability to store data due to wear.

  10. it's not a lottery or raffle on ICANN To Replace 'Digital Archery' Program With Raffle · · Score: 1

    It is just selecting the order by lot.

    Lotteries and raffles are sweepstakes and are restricted. In a sweepstakes, you pay X amount of money but don't necessarily get X amount of product. The biggest restriction is that each person who enters must receive something of at least the value of what they paid. And since you don't want to pay everyone out, that effectively means the entry price must be $0 to satisfy this restriction.

    But in the iCANN system each of these companies "wins", they all receive what they paid for, just the order changes. Legally, there's no problem with this.

  11. Isn't this like the number on a ballot stub? on Federal Judge Says No Right To Secret Ballot, OKs Barcoded Ballots · · Score: 1

    Where I vote, you get a ballot stub when you vote. Later, you can go down to the place of records (county seat, etc.) and then use the stub to make sure your vote was recorded. They can do this because there's a number on the stub that matches the one on the ballot. The number isn't recorded or anything when you vote, but the ballots are stored by number (and district) so they can be retrieved and verified later.

    It turns out Humboldt, California scans and posts all their ballots online, again, you can match them up by the number.

  13. Apple and Google say bio-gas on Microsoft Wants To Nix Data Center Backup Generators · · Score: 1

    And Bloom box would like you to believe it too.

    That doesn't necessarily make it true.

    Bio-gas requires a source (a trash dump effectively) and a lot of processing (drying, etc.) to be burnable in a Bloom Box. There's little evidence companies have gone through this trouble, it's more likely they are just pumping natural gas in.

    Maybe you should ask Barret Brown if we've stopped being civil?

  15. well written, detailed and interesting on 100GbE To Slash the Cost of Producing Live Television · · Score: 4, Interesting

    You don't see that all the time on slashdot.

    Great article.

    I think many are getting confused here and think that this article is about reducing the cost of producing live TV on a shoestring. The figures in this article are very high, but for professional video production, existing figures are also very high.

    If you take into account that this could allow production trucks to shrink in size a bit (RG6 takes up a lot of space), the price of this new way could be even lower.

  16. Re:Cynical view of the stock market on Mark Cuban Blames Himself For Losing Money On Facebook IPO · · Score: 1

    He says he was not buying the company on the firm foundations principle. He was buying it because he thought it would get a momentum pop and he could sell it off at a higher price.

    And often, even with sketchy companies, getting in on an IPO affords you the opportunity to make money off the imbalance between supply and demand on day 1. It's been this way a long time, see the IPO craze of the 1970s.

    The only big problem is sometimes this won't happen and you will lose money on your trades. That's what happened here and Cuban seems at ease with it.

    So I don't see why you criticize him and call him an internet mind-reader. It kind of feels like you read the quote and not the article.

    I do agree with your first paragraph, especially in the case of an IPO. Mark's sentence about no one selling a stock thinking it will go up is not strictly true. But it isn't really an important of the message delivered in the article, it's just the most quotable.

  17. It's not a town, it's not outside anything on California's Unspoken Health Problem: Brain Parasites · · Score: 2

    This story makes it sound like you're in the burbs. Sunnyvale is a city in the heart of Silicon Valley. It borders both Cupertino (home of Apple) and Mountain View (home of Google) and has more residents than both of those put together. Would you read a story on slashdot relating how Cupertino is a town 45 miles from San Francisco?

    Weird.

    'Just to help you keep things straight, remember this is a separate case from the one that ended exactly a week ago with a decision in Apple's favor to the tune of more than $1 billion in damages.'

    The 'it could temporarily halt sales in the U.S. market even before the trial begin [sic]' in the summary should have been a tipoff.

    And when you start getting angry over people's siglines, you really make yourself look petty and foolish. You also make yourself look like a person who doesn't have enough objectivity for your judgment of whether 'you're [Apple] pissing away whatever good-will you may have had left' to mean anything at all.

  20. Re:Why bother? on Photo Reveals UK Plan: "Assange To Be Arrested Under All Circumstances" · · Score: 1

    They came out and said it straight out in Swedish media right after the trial

    What trial? There has been no trial yet.

    In fact as of right now they can't get the women to testify, and the women cannot redact their previous testimony as it has already been entered into the public record.

    Can't get the women to testify? To what? There's no proceedings right now, why would they be testifying at the moment?

    Without that he is perfectly legitimate in being fucking terrified of going back there.

    Well, given that Sweden's government has treaties in place they must honor, they cannot give him a guarantee he won't be extradited to elsewhere. Sweden would have to agree to give him asylum in order to shield him against extradition requests, and they don't seem to be inclined to so do. So he's going to remain terrified I guess.

  24. we see this with filesystems on Content-Centric Networking & the Next Internet · · Score: 1

    And it has the same issues. 15 years ago everyone said that we'd move past using file to store stuff and just go for the stuff we want. Microsft had WinFS for example (part of Longhorn).

    But then the question comes where do you actually store the stuff?

    The real change came not by eliminating using files to store stuff, but by changing how we retrieve stuff.

    And this is the same way. Changing how you locate stuff on the internet is not going to remove the need for TCP/IP. You're still going to have to contact a machine to get the data and it'll have to send it back to you and the internet will have to route it between the two.

    And not to put down Van Jacobson, but we're already well along the path. I remember when URLs first started appearing in ads, some day in the future, we'll look back and remember the days of URLs in ads as quaint.

    Why go through the trouble of creating a URL to and even a short URL (http://bit.ly/itsmbmam) to the sampler for My Brother, My Brother and Me when if you search for "mbmam sampler" the sampler is the first result? Some day we'll stop even bothering. At least it seems like it to me.

    So I don't get how the NASA coverage is better except that it's free.

    If you think watching the event live with no commentary is better, don't watch the primetime coverage instead. This goes for the Olympics, it goes for the Curiosity lander.
