  2. There is no "wiggle room" in the Catholic Church on Vint Cerf and Others Form Advocacy Group · · Score: 1
    The Church's official doctrine statements are here. These come from what is now called the Congregation for the Doctrine of the Faith, headed by Cardinal Ratzinger. One of his official titles is "Grand Inquisitor", although he doesn't use it. His job is to find and stamp out deviations from approved doctrine.

    Here's the official hard line:

    • 5. Regarding the grave sin of abortion or euthanasia, when a person's formal cooperation becomes manifest (understood, in the case of a Catholic politician, as his consistently campaigning and voting for permissive abortion and euthanasia laws), his Pastor should meet with him, instructing him about the Church's teaching, informing him that he is not to present himself for Holy Communion until he brings to an end the objective situation of sin, and warning him that he will otherwise be denied the Eucharist.

      6. When "these precautionary measures have not had their effect or in which they were not possible," and the person in question, with obstinate persistence, still presents himself to receive the Holy Eucharist, "the minister of Holy Communion must refuse to distribute it" (cf. Pontifical Council for Legislative Texts Declaration "Holy Communion and Divorced, Civilly Remarried Catholics" [2002], nos. 3-4). This decision, properly speaking, is not a sanction or a penalty. Nor is the minister of Holy Communion passing judgement on the person's subjective guilt, but rather is reacting to the person's public unworthiness to receive Holy Communion due to an objective situation of sin.

      [N.B. A Catholic would be guilty of formal cooperation in evil, and so unworthy to present himself for Holy Communion, if he were to deliberately vote for a candidate precisely because of the candidate's permissive stand on abortion and/or euthanasia. When a Catholic does not share a candidate's stand in favour of abortion and/or euthanasia, but votes for that candidate for other reasons, it is considered remote material cooperation, which can be permitted in the presence of proportionate reasons.]

    Any questions?

  3. Going public via a reverse merger on SunnComm - Bomb or DRM Success Story? · · Score: 3, Informative
    Going public via a reverse merger is not that uncommon. It's usually loser companies that do it.

    A typical comment on reverse mergers: "It's a perfect setup for a 'pump and dump' stock scam. Take a stock that has been trading for pennies, merge it into a business that has at least the facade of respectability and a presence in a market that is perceived as hot, hype like hell, sell off as many of your shares as possible, and make a run for the border before the price drops like a rock. There have been enough of these to give the whole approach a dubious aura."

    A reverse merger, unlike an initial public offering, doesn't raise any money for the company. It costs money, and at the end, you have a publicly traded stock nobody cares about. Which you then have to hype. So they are an inherently suspicious transaction.

    Here's an example of a reverse merger involving a company claiming to be engaged in gold mining, biotech, and casino gambling. Reverse mergers tend to be at that level of flakeyness.

    Automated processing requires much cleaner data than you are likely to get from a multitude of sources that don't have to go through validation.

    This is a well-explored area. Look into the history of SGML, or of EDI. Look at how hard it's been simply to get invoices and purchase orders into formats that work between companies. It not only takes standards bodies. It usually takes one dominant player who forces their suppliers to do it their way.

  8. Keyhole just censored the White House roof on Spysats Keeping Watch on the U.S. · · Score: 3, Interesting
    I just noticed that Keyhole recently censored the White House. A few months ago, you could see rooftop details. Now it's all a uniform brown. They also censored both Executive Office Buildings, overpainting them with a uniform green. The Capitol and the House and Senate Office Buildings have been blurred, in an ugly, pixilated way. Not the Supreme Court, though. Or, for that matter, the Pentagon.

    If you try GlobeExplorer, you get an uncensored image until the last two zoom levels. Then the White House turns brown.

  9. Why this is a bad idea - it's a taxonomy on Tim Berners-Lee and the Semantic Web · · Score: 4, Insightful
    The big problem with the so-called "semantic web" is that trying to taxonomize ideas doesn't work very well. Full-text search works much better.

    In the beginning, we had library card catalogs, with their painful attempts to index and cross-reference books. That works well in some areas, typically ones where names of people are significant. Attempts to apply the same approaches to technical papers worked less well.

    There's a very elaborate classification system for patents. When you had to look through patents on paper or microfilm, it was essential. Now that we have full text search, it's used less and less.

    A modern example of this approach is the ACM Taxonomy, a structure into which all computer science can be fitted. (As an exercise, try to put the current Slashdot stories into that taxonomy.) Nobody actually uses that taxonomy to find anything.

    As to data interchangability, that's a separate issue, and more of a standards one. The big problem for publicly available data is that the cost of encoding the data is borne by different people than those who benefit from the encoding. Many companies don't like having all their product and pricing information easily searchable by price. (Froogle may change this, because Google has so much clout.)

    I've spent some time dealing with public financial reporting. There's opposition to detailed disclosure in a standardized format. Many companies don't want their detailed information to be too easily analyzed. Embarassing results show up.

    The future is better search engines, not user-created indexing data. As we've painfully learned, a search engine must look at the same data a human reader would, or it will be lied to. Lied to to the point of uselessness.

  14. This is total vaporware on Pumps Without Moving Parts · · Score: 2, Informative
    When you finally find the paper, it says
    • Abstract - The commercial feasibility of small scale solar ORC for distributed generation and CHP is demonstrated. This has been achieved with an exergy analysis of over 150 commercially available solar hot water collectors, a survey of candidate working fluids and by adapting rotary refrigeration compressors to run in reverse direction as expanders/asynchronous generators. A computer code combining the results of these sub-studies has demonstrated that self-stabilisation close to optimum conditions for given irradiance may be possible without electronic feedback control. The principle obstacles encountered included oil migration, face and tip sealing problems and low expansion ratios.
    "Commercial feasibility" is total bullshit. They haven't even built a prototype.

    If you want solar powered water pumps, they're commercially available. A complete kit, including solar panels, is $1,697. But they're not really cost-effective. Windmill pumps still outperform solar, and newer pumps will work at low wind speeds.

  20. Re:Why this is not going to help much + a better w on Flexible Sensors Make Robot Skin · · Score: 3, Informative
    The problem is not that you can't do it. It's that the market is so dinky that tooling up to do it isn't worth it.

    It should be feasible to make integrated silicon strain gauge/amplifier/interface chips, embed them in a flexible printed circuit, and laminate them into a skin-like laminate with appropriate tough, soft, and hard layers. But the processes involved are all high-volume ones - it's hard to do this economically in small volume. And there's no market for a process that turns out big rolls of this stuff.

    There's a lot of stuff in robotics that's like that. Linear motors and laser scanners both cost about 20x what they should. because the volume is tiny. Even basic servomotos and servo amps cost 5x as much as they should, based on parts cost.

    It's getting better, though. More and more parts needed in robotics are becoming off the shelf. I run a DARPA Grand Challenge team, and over the last year, many of the components you need for that have become far more available.

  23. What's coming on Vehicles of Tomorrow? · · Score: 5, Interesting
    Lots of little stuff.

    Proper starting. Automobile engines are started all wrong. Cranking, compression, fuel, and spark all start at the same time. Oil pressure comes later. As a result, half of engine wear occurs during start. Many big engines (locomotives, marine diesels, some big tractors) are started properly - oil pressure first, then a few turns with compression released to oil up the cylinders, and finally combustion starts. Wear is much reduced.

    Once 42-volt electrical systems become popular, and valve control goes electrical, we may see electric booster oil pumps and valve actuators. Once you can crank the engine with compression off and oil pressure up, you need a much smaller starting motor. The starting motor and alternator can then be combined.
