  1. Outgassing on NASA's LCROSS Mission Proves Lunar Ice Suspicions · · Score: 1

    Interesting paper. After seeing page 39 I now have an image of moon farts locked in my mind. "Transient
    Lunar Phenomena" indeed.

    It seems like they are saying 'find the largest sources of outgassing and you will find the highest concentrations of water' (at the poles), caused by vapor phase changing to subsurface ice.

  2. Speaking as a DM... on Surfacescapes D&D Demo · · Score: 5, Interesting

    For D&D I would like a Surface that can:
    -bring up maps as needed, to be played on with Surface-aware miniatures that track positions
    -display a combat state tracker, like a game scoreboard, with initative, hit points, state tracking (dazed, on fire, etc) in clear view for all players
    -combat-aware board that determines flanking, cover and similar bonuses based on mini locations
    -dice that auto-sense the roll and calculates your bonuses, displaying the results
    -full web integration with the D&D sites if you need to reference a quick rule (there are already Iphone apps that do this)

    Actually that sounds like more trouble than its worth. These days we use a clear piece of acrylic and dry-erase markers over a grid map. Simple and effective.

    Computers already have a place at our gaming table, for some it substitutes for a paper character sheet and its nice having a full rules library within reach. It may have gone a bit far when the other week three players were screwing around on their Blackberries at the same time. Turned out they were plotting something they didnt want the DM to listen in on.

  4. Re:so they've rebranded vista... on XP Users Are Willing To Give Windows 7 a Chance · · Score: 1

    The benefits are certainly there when you do trim.

    I'm running Win 7 (technet version) on a netbook, that when running on batteries is downclocked from 1600 to 800mhz. Win 7 runs fine on it, nearly as quickly as XP. According to 'powercfg /energy' the biggest CPU user when idle is Window's license service, at a hefty 1% CPU use.

  5. Re:What is "CA"? on German Health Insurance Card CA Loses Secret Key · · Score: 5, Informative

    I will simplify, but basically a CA (Certificate Authority, that much of the parent wasnt a joke) is a server that creates encryption certificates. In this case, SSL certificates. For example, when you goto https://mail.google.com/ that SSL certificate was created by the Thawte SGC CA. Thawte is one of many companies that you can pay to create you an SSL cert, so your users can communicate with your server via https.

    The CA itself also has an encryption key, which is stored on hardware. In some cases its a PCIe board, others its a removable PCMCIA card, etc. This particular CA used an add-on board which lost power during operation, wiping out its only key. The board seems to have been working as intended, preventing attack (removal of board, which would cause power loss) by wiping itself.

    Without that key, the CA can no longer create revocation lists (CRLs, lists of certs a CA has created that have since been revoked or expired) or any new certs. They are dead in the water, also causing every cert they have ever made to become invalid as they can no longer be checked against a recent CRL. They have to start from scratch, recreating every_single_cert.

    This was only a test system, but if this happened in reality 80 million Germans would have invalid health cards. At least they discovered the value of a backup during testing.

  6. Re:usage based on The Dilemma of Level vs. Skill In MMOs · · Score: 1

    "Dent our armor, even weaken our sword arm, but don't put us on the edge of a virtual cardiac arrest until we get magically healed or wait an hour."

    Sounds like you are describing 4th edition D&D and its healing surge system. Basically, everyone can heal to full if they take a 5-minute rest after battle. Doing so expends 'healing surges'; how many of those you get depends on your class. Its a huge departure from previous versions which relied heavily on clerics and Cure Light Wounds.

  7. AllwaySync on How Do You Sync & Manage Your Home Directories? · · Score: 1

    freeware @ http://allwaysync.com/

    I was playing with this for the first time last night, it gets the job done. Sync software with a nice GUI, and I was easily able to backup my systems to a 1tb backup drive in a reasonable time period. It has the usual features and can sync in multiple directions (one to many, bidirectional or one way).

  8. Re:Windows has ESP? on First Look At Windows 7 On an Entry-Level Netbook · · Score: 1

    "I have no idea what criteria Windows uses to determine what my "likely" programs are"

    From wiki:
    "The prefetcher works by watching what code and data is accessed during the boot process (including reads of the NTFS Master File Table), and recording a trace file of this activity. Future boots can then use the information recorded in this trace file to load code and data in a more optimal fashion. The boot prefetcher will continue to watch for such activity until 30 seconds after the user's shell has started, or until 60 seconds after all services have finished initializing, or until 120 seconds after the system has booted, whichever elapses first."

    Prefetch was part of XP. Its been expanded into Superfetch in Vista and 7. Its basically a more refined version, taking into account time of day and system use trends. For example, if antivirus scans run at 2am, superfetch loads applications back into memory later on before typical use starts at 8am so the user opens Office quickly. This is done at very low I/O. Theres actually been a lot written about it, but I would start with http://technet.microsoft.com/en-us/magazine/cc162480.aspx

  10. Re:Classical mechanics 101 on Black Hole At Center of Milky Way Confirmed · · Score: 1

    Yeah that was poorly worded. Point being that this paper did not prove a "black hole" exists at galactic center, but that stars are rapidly orbiting a central point. Classic mechanics dictates the central point must contain a huge mass, because only gravity moves stars, and only mass creates gravity. And that may be true, or we may find exceptions to the rule. Figuring that out either way would be a hell of a day for science. Studying the galactic center could be the best way to find out.

    Interesting bits from the paper:

    "Equally interesting is the nature of the mass
    responsible for the strong gravitational forces observed.
    While the measured mass makes a compelling case for a
    MBH, the exact form of the potential encodes answers to
    many interesting questions."

    And "In addition to the MBH a substantial amount of
    mass might reside in form of a cluster of dark
    stellar remnants around the MBH"

    Finally, "a single point mass potential is (still) the best description
    of the data."

    Amazing paper. And yeah its old, October, but ESO just got around to writing the press release with the usual science-news bells and whistles. "The most detailed view ever of the surroundings of the monster lurking at our Galaxy's heart -- a supermassive black hole", oh the drama! Hence it hitting the 'news' sites today.

  11. Direct link to the paper on Black Hole At Center of Milky Way Confirmed · · Score: 2, Informative

    http://arxiv.org/abs/0810.4674

    Amazing that a star they studied orbited the galactic center in only 16 years.

    The paper seems to assume the existence of black holes; it addresses their observations rather than any theoretical causes. Saying these observations confirm a black hole seems a bit of a stretch. It just confirms that stars are circling around the galactic center, which may or may not contain anything at all.

  14. A vote for POTUS is for far more than a POTUS on McCain Campaign Uses Spider/Diff Against Obama · · Score: 4, Informative

    When you vote for president, you get far more than a president.

    Behind the POTUS candidate comes a legion of people who will set the policy and tone of the nation for years to come. Supreme Court justices, Cabinet members, hundreds of others at every level of government.

    Dont forget what happened at NASA, the EPA, the Justice Department, DHS, etc. All hit the headlines the last few years with major scandals brought on by POTUS-appointed bureaucrats.

    Point being, presidential elections arent about single issues or a single candidate, but a change in national leadership for all issues at all levels. Sometimes you have to hold your nose and vote for the party most closely aligned with the future you desire. Any party will bring in some crazies, its unavoidable.

  18. Flag Telecom on Fifth Cable Cut To Middle East · · Score: 4, Informative

    Whether the cables are being cut by ship anchors, Navy Seals or lasersharks, there are slower alternate routes. In a pinch most Gulf-region ISPs can route the other way, through Asia, under the Pacific Ocean to America. Obviously that degrades connection quality. Backup routes were contracted after the tsunami damaged so many of the undersea cables at once.

    The BBC has a decent article on the issue, at http://news.bbc.co.uk/2/hi/technology/7228315.stm
    The cables (at least two of them) are owned by http://www.flagtelecom.com/, they have updates on repairs on their news page and a nice map of the cables. Their Gulf-region cables are described as a "Self healing Gulf loop, providing maximum design capacity of 1.28 Tbps. Initial launch capacity 50 Gbps.
    Four fibre pair route linking the Gulf to Egypt and India. Design capacity of 2.56 Tbps, with initial launch at 90 Gbps.

    There was a similar article on the BBC today at http://news.bbc.co.uk/2/hi/health/7205094.stm

    It looks like the same cause in both the girl and the kidney transplants - stem cells getting into the bone marrow. Maybe they could avoid the marrow transplant if there was a way to produce stem cells of the donor, perhaps from the donated organ.

  24. Baby steps on The Lost Art of Class Balancing · · Score: 1

    That is the key - class balance changes need to be taken carefully. Sweeping changes in a single update are poor form, balance changes should be gradual and monitored for effect. It is far better to make frequent, small tweaks in the direction of balance than to make one large update.

    The biggest offenders are new expansions, and the resulting mudflation. These are typically lightly tested at the endgame level of play, and are released to live games to cause havoc. An current example would be Blackwing Lair for WoW, which is not being publically tested. This limits testing to the dev team, which is too small a test set to find all serious issues. Major post-launch changes are inevitable. Daoc's ToA expansion also comes to mind as falling into the same trap.
