  1. Telcos and Google get it right? on Intel Shows Data Centers Can Get By (Mostly) With Little AC · · Score: 1

    I've noticed that often 'old-school' telco data centers often seem to be much more sparing with the AC running 70F-85F vs. the 'high-tech' data centers who tend to run 'freeze your ass off' data centers. Something has always told me they had something (whether it was just being cheap or not).

    Also, google put out that report a few years ago (google: "Failure Trends in a Large Disk Drive Population") and it basically proved that too cold (59F-86F) actually causes more problems early in the drives lives than too hot. Optimum temperature is something around 86F-104F for both early and late in life.

    Obviously ambient temperatures effect the drives core temps, but it shows that you can run them hotter than typical data center dogma would have you believe.

    Its ironic that an industry that is so 'logical' in nature doesn't use science to determine the ideal temperature. "Cold" to humans doesn't necessarily mean anything to a computer. I wish we had more large studies for this sort of stuff, we could probably save a lot of energy.

  2. Re:Interferometry on Virtual Telescope Zooms In On Milky Way Black Hole · · Score: 3, Interesting

    Just out of curiosity, how far could you push something like this? If you had an array of Hubble sized telescopes in space and could put them whatever distance you'd like from each other, what sort of results could you get?

  3. Forget the mirror! 3.2Gigapixel camera! on "Perfect" Mirrors Cast For LSST · · Score: 2, Interesting

    The digital camera in this thing generates 15TB of data a day from its 3200megapixel camera. I'm assuming it has an array of sensors, but thats still a ridiculous amazing pixel count.

    Good Source is Storage Review

    The top 34 drives all do at least 54mb/sec MINIMUM and at least ~80MB/sec maximum. The top 15kRPM cheetah doing 82.7-135MB/sec.

    If i were to pull a number out of my ass I would say 78-135MB/sec (min/max) on the new 1.5TB drives.

    I would say if you have 750gig seagates and you are only getting 25MB/sec you have a bottleneck. Those drives should do a MINIMUM of at least 40MB/sec...

  5. Re:It wasn't a fair comparison on Comparing 3G Networks · · Score: 1

    I agree completely. No actual data from when/where the samples were taken. If you look at the coverage maps sprint and Verizon have much larger 3G networks. From my experience sprint has been very fast for me and several people I know. Obviously this to, is too small a sample size to rate a network. But, that article didn't really clarify anything. Especially considering he said several times he was not connected to a 3G network for Sprint and Verizon, did he average in non-3G network numbers?

  6. Heat? on Data Center In a Shoe Box · · Score: 1

  7. Alternative chemistry confusion... on TSA Limits Lithium Batteries on Airplanes · · Score: 1

    Its going to get even worse when alternative chemistry batteries like altairnano's and others with alternative anode materials. If its still a lithium battery but is totally safe they aren't going to be able to distinguish.

    Someone needs to sitdown and do safety testing and come up with a standard. Batteries stamped with the 'safe to fly' or 'safe to ship' or some such get on, others get rejected.

  10. Artist gets attention for art exhibit! News at 11! on Perpetual Energy Machine Getting Lots of Attention · · Score: 1

    Is it me or did everyone miss the fact that this is an ART EXHIBITION!? The guy just wants attention like every other artist. I'd say he's doing a great job at it, staying in character and everyone is talking about him. Its perfect as soon as its debunked he'll probably talk about how the whole thing was a social experiment on how people react to things they can't prove or some sh!t like that.

    At this moment in time, I would say its a no-brainer to go with blu-ray. I've also noticed at Fry's dozens of choices for BD media and NO HD-DVDR at all...

    But i've managed not to lose anything big [insert safety superstition here] except 2 CD-Rs (physically lost), and a 60gig with some anime on it (before I did RAID), since around the late 80's. I've found the most important thing is to just keep migrating drives and media. When blue-ray gets cheap i'll consolidate all my DVD-R's and spool up the old ones.

    They've launched a site with a few videos on it.

    Isn't the definition of a portal something that takes you somewhere else?

    Focus-stealing absolutely drives me up the wall. Ironically faster computers can be even worse than slower ones with this. I can't tell you how many times I've started typing a URL only to end up in the google search box half way through.

    If you are using an input box all other attempts for top focus should be put on hold unless a critical error has occurred that would prevent that input box from functioning. I'm sure there are tons of ways to get the users attention when he's finished.

  20. Contract agreements without legal representation. on Refilling Ink Cartridges Now a Crime? · · Score: 1

    IANAL but...

    In MANY types of contract negotiation the side writing the contract is compelled to advise you to seek representation to make sure you understand the agreement you are signing. If you just blindly sign, much of the time it can nullify the agreement because one side had a lawyer and you can't be expected to understand complex legalese ... I mean how fair is it that a corporation can hire a team of lawyers to carefully craft a complex agreement that you as an individual have to accept completely IN FULL with zero negotiation on your side nor ANY legal representation on your side. That seems entirely wrong.

    With shrink-wrap and click-through licenses you can't be expected to have a lawyer advise you every single time, which leads me to believe that if society is willing to accept this as a reasonable thing, THEN there should be some sort of public body that turns them in to PLAIN ENGLISH that any layman can read and understand.

    Or, get ride of them completely. As far as I'm concerned entering in to a legal contract by opening or clicking anything is totally ridiculous.

    Unfortunately, to do a real review, you would have to 'live with' each solution for at least a week to get a good feel for it.

    SnapStream - Windows
    BeyondTV - Windows
    MythTV - Linux
    MCE - MCE...
    Tivo - Linux Dedicated Hardware
    ReplayTV - ? Dedicated Hardware
    EyeTV - OS X

    Now THAT would be a nice roundup. Start with a feature comparison chart, price, compare the look and feel, reliability, benefits, expandability, etc... Then really get in to how living with each system was and how good the support and updates are, since PVR software is changing so rapidly.

    Unfortunately, looking at some specs on a web page just doesn't give you a good feel for what you are getting with PVR's.

    One final note if you want it to be family safe...
    1. make sure IR receiver can't be tripped on

    3. Make sure it boots when the power comes on and SageTV auto launches

  25. Re:A land-line...? on VoIP And Cell Phones Eroding Traditional Telecoms · · Score: 1

    Lol, yeah they were much bigger, although there are plenty of models that still do dual mode analog/digital (just at lower power levels). Its more of a power issue than a size issue.

    3-5x the power means 3-5x less battery life. But it would be nice if that much power was at least AVAILABLE. With digital cell phones they scale the power needed as you get closer and farther from cell sites.

    It baffles me why they don't have exactly what you said. Car phones (or an in car adapter) should be able to use much more power and have a better antenna. Both of those would boost range a lot.

    But again, with a few people at high power it may mean less callers in the same spectrum, which they don't want.
