  1. Re:Implications on Claimed Proof That P != NP · · Score: 2, Informative

    It is sortof a negative result. It has been known for forty years that many (10,000s) of difficult problems share a common difficulty, that makes them prohibitive to solve: NP-completeness. It was proven in the 70s that if you can solve one NP-complete problem fast, you can solve them all fast. This new result claims to prove that you cannot solve any NP-complete problem "fast". Some nerdy NP-complete problems are, for instance: how to make a certain circuit (CPU) using as few NAND gates as possible (i.e. faster hardware cheaper) or how to wire your motherboard as efficiently as possible (both how to draw the wires, and how to place the components). This says that it might ake more than a human lifetime (or Sun's) lifetime to solve any NP-complete problem. Some would like to see it as good news for cryptography, since it make some ciphers provably hard (however I am not aware of any such cipher -- unless it is proven that RSA is in NPC or in NPI).

    Their case really isn't as shoddy as it seems.

    The case of existence is open and shut.

    Every serious investigation on the UFO phenomenon has concluded that they are real (US, Soviet, British, Feench, Mexican, Brazilian miliaries for instance). That is not the issue anymore.

    The issue is to understand what we are seeing. Remember, UFO is not the same as ET. There is no single explanation that could explain the vastly different type of reports. One of the difficulties is that there is no clear border what reports to accept. The cases get continuously more and more wicked and logic defying.

    To give three examples of cases along the scale:
    Easy to accept case (probably an unknown natural phenomenon): http://en.wikipedia.org/wiki/Hessdalen_light
    Classic case: http://en.wikipedia.org/wiki/1976_Tehran_UFO_incident

    Parent is modded funny..!?

    The link to the official report from British Ministry of Defence is: http://www.mod.uk/DefenceInternet/FreedomOfInformation/PublicationScheme/SearchPublicationScheme/UnidentifiedAerialPhenomenauapInTheUkAirDefenceRegion.htm

    UFOs are called 'UAP' (Unidentified Aerial Phenomena) by the Brits, and to save you the trouble, it concludes that:

    * "Aerial phenomena of the type consistent with those reported as UAP, and with exceptional characteristic, certainly exists ..."

    but

    * There is no evidence that the phenomena is anything but naturally occuring.

    The first point is interesting, since it is the conclusion of many military reports (US, French COMETA, Soviet, Mexican, Brazilian...) published on the topic. It shifts the debate from whether UFO:s are real or not, to discussing what they might be.

  13. Re:Programming contest on How Do You Find Programming Superstars? · · Score: 1
    I was about to say something similar. Programming contests shows that a person loves programming. However, TopCoder, ACM or univ or Valadolidl (sp) stuff are not ideal. Those competitions are more about coming up with a witty function quickly (within an hour or so per task) rather than engineer a program.

    The ICFP programming contest would be a far more better meter, since the contest is long enough to require the programmer to create several tools, and/or and an architecture that they can extend during the contest (it's three days, but believe me, the guys we are talking about produce in three days code that would take weeks for the mortals to produce).

    Basically all excellent programmers I have met has their own framework of reusable code/classes/modules (in their favourite language), and they prefer to use it. They might even be passionate enough about it to accept lower pay in order to find a job where they can use it instead of tools decided by management.

    My 2 cents.

Why should software be any different? Are there any other industries protected by such a strong veil? So there are no patents on any components in a car?

    This results in an interesting question : say someone is buying a car which has patent protected components in it (say in the engine). Where did that person obtain the right to use that patented technology?

    Some time ago I read another a related discussion about authorized resellers, how can a corporation stop anyone but their authorized reseller from selling their products?

  23. Analoguos to music on CD only on Disney Says, You WILL Watch the Ads · · Score: 1

    This is another example of corporations trying to clinge to their outdated business models. Once upon a time it was a problem to distribute TV programs to the people, you had to centrally broadcast it to all at once, and what you broadcasted everyone watched, since that was the only way to see the content. TV ads, as we know them made sense back then. Today, TV programs can like music and movies, be distributed individually and on demand. Trying to force ads in there is like avoiding to sell music digitally and only on say a CD. It is doomed to just annoy the customers, and there will be pirated versions available in a form the (potential) customers would prefer(ie. music as mp3s, TV shows as xvids - without the ads). Sooner or later the old business model will change. One guess is that the replacing model could be some more extreme version of todays product placement -- ads and content merge in a way that makes them hard- or unseparable. //T

    Absolutely. The problem is that the *AA and friends have not gotten and probably will never get the fact that their stranglehold on the packaging and distribution of content is about to die a painful death. If they had anticipated that in the early 90s and adapted to it, they'd be rakin' it in by now from all sides

    Actually there is more to blame than the companies. At least where I live (Sweden) corporations dealing with IP has a problem with accounting of the value of their IP.
    What is the value of the right to sell, say 10,000, copies of a song?? Under the current rules, the value of this asset is 0. But if you burn 10,000 copies to CD:s and stock them, that is an asset with an value of 10,000 x X!

    It is backward, yes. But companies that don't have enough assets on paper are forced into bankrupcy. This is one problem for IP companies leaving the physical medium model of business. And that part is not their fault. //T

    lso, what is the "other side" of the story?

    I would recommend to watch "the great global warming swindle" (available at your favourite bt tracker).

    Regardless what your stance on the issue is, one should always listen to both sides. This documentary contains lots of interviews with (chosen) climate scientists about their views on the issue. One intersting argument they make there is that the levels of carbon dioxide usually rise *after* the warming, and not before (and maybe this is one fact GP claimed that Gore was fast and loose with?). An alternative theory for the cause of global warming pointed out in the documentary is the relation between sunspots and temperature (like for instance the Little Ice Age and the Maunder Minimum).

    Intresting.
