  1. Re:OMG, I used Kiesler in 1976 on Five Free Calculus Textbooks · · Score: 1

    Infinitesimals suppose to be more "physical" then limits. However they require formidable algebraic foundation and IMHO not easy to work with...and I never heared physics actually use them, in their rigorous form. To start calculus from infinitesimals is about as difficalt as start arifmetics form axiomatic set theory....

  2. Re:What about Gaming? on Seattle Times Reviews Desktop Linux Distros · · Score: 1

    Gaming industry support whatever give profit. If there will be big enough market for Linux games industry will support it. If there will be small market it will be supported by small/independent developers. For now market just doesn't exist. BTW just now game industry does not support windows as before, windows share steadily decrease in favor of consoles.

  3. It's a pure propaganda. on Manufacturing 1 PC Takes 1.8 Tons Of Raw Material · · Score: 0, Troll

    The car manufacturing cost in raw materials a lot more (steel only make more then 800 kg ). I think it's a lot more reasonable to ask people use old cars, instead of using old PC.

  4. Re:"Free upgrades" on AT&T Wireless Phone "Upgrades" Aren't · · Score: 1

    I'm not so sure about NOkia 6600 vs P900 , though I agree about 7250. P900 cost now almoste twice as Nokia 6600, but I'm not sure it's twice better. The biggest adavntage of P900 is a big screen, but it's CPU isn't powerful enouth to generate even complicated full-screen 2D picture, not speaking about 3D. By price/performance ratio I think Nokia 6600 about the same or better P900 (of cause after Nokia fix all the bugs )

  8. Some comment. on Tracking Via Anonymous SIM Cards · · Score: 3, Interesting

    Despite Swiss law about not buying SIM cards anonimously SIM cars still freely awailable for online shopper. But all this affair show that Al-Qaeda is not quite tech savvy. List of the phones on the paper ? Not encripted ? Well it's sound good :). They also didn't use smartphone with software voice scrambler, though scrambled talk also could rase suspicion. Don't know how many people scrambling them really. Not 100% sure but I think existing high-end smartphones powerful enough to produce unbreakable scrambling. Even they arn't encripted text messagess could be made practically unbreakable ...

  9. That is not most interesting string approach to BH on Famous Hawking Black Hole Bet Resolved? · · Score: 1

    Tere are other, conceptually more interesting. Gary and Juan in black hole final state suggested that blackhole itself have boundary condition in infinty - final state, and carry only limited amount of information. Here is Lubos Motl's explanation of the article in popular terms: "... They propose that the final state that defines the final spacelike singularity (of a Schwarzschild-like black hole) can't carry any information - the evolution approaches a universal state whose identity is determined by the semiclassical data and nothing else. In popular terms, a person who falls into the black hole knows his or her future - he will die. In fact, he can know it even at the microscopic level - the final state is a unique quantum state, they say. Once he or she hits the singularity, one can imagine that he is reflected - by a complicated but concrete unitary transformation - and becomes Hawking radiation that travels backwards in time inside the black hole. (The arrow of time might seem reflected, but Juan and Gary argue that such effects won't be measurable because of the space and information limitations inside the black hole.) Once this Hawking radiation reaches the horizon, it is transformed - via the Unruh state - to the Hawking radiation that escapes to infinity. All steps in this description were unitary, and one can show that the information will be preserved. The possible modifications of causality, locality, information loss, black hole entropy and its microscopic origin, (in)dependence of the degrees of freedom inside and outside the black hole, quantum treatment of singularities, topology change, the arrow of time and similar issues is what I - as well as most "real" quantum gravity practitioners - call "interesting questions about quantum gravity".

  13. Re:I hope china builds a nuclear rocket on China Sending Two People Into Space · · Score: 2, Informative

    You lost me here.... the EM pulse is generated from all that energy being released and doesn't need a medium to travel in, as it is electromagnetic AFAIK ECM is not produced by explosion itself, but a result of air ionization by the radiation produced by explosion. There is no air to ionize in the vacuum, so no ECM.

  15. Re:I hope china builds a nuclear rocket on China Sending Two People Into Space · · Score: 5, Informative

    In fact there 2 type of Nuclear propulsion : Without fallout (Nuclear Termal Rocket (NTR) - basically just flying reactor) and with fallout ( Orion - nuclear bomp explosion pushed ship, Nuclear salt water rocket NSWR). AFAIK there is still no usable "build now" NTR design, and overall NTR probably couldn't make one stage to orbit and back reusable trip. NSWR is a radioactive disaster, usable only in space. Orion - battleship sized spaceship on the pushing plate, pushed by nuke explosion probaly most realistic nuclear design, and probaly could be built now. If launched in the Antarctica, radioactive pollution wouldn't be quite disastrous, but still costing one cancer death per launch (for all the world), by some estimation. So until the progress with NTR nuclear propulsion is better used in space (and there is no electromagnetic pulse in space for nuke too)

  17. The same prolem for all new MMORPG on Will Harvey On Virtual Worlds, Technology Curves · · Score: 5, Interesting

    That is the comon pitfall of all latest MMORPG: desiners rely on player created content and player-driven economy. The problem is - it never work. Worlds designed for player created content are blan and empty. Player-driven economy unwieldy, inconvinient and is not fun. To be creative players have to be provided with a lot of extensive tools and abilities, and that kind diversity usually destroy balance. No balance = no fun. More restrictive tools - no players creativity. The "There" seems too abitious - they want all genres in one game. Too much framework usually mean too little premade content, and that usually spell disaster...However there's always a hope that this time they will manage to do it right...

  18. MMORPG anyone ? on Ebay Suspends Phone Number Sales · · Score: 1

    That is exactly the same situation as with MMORPG in-game characters/items trading outside of the game. High-level characters/rare items in most popular games sold for hundreds dollars. Most MMORPG don't recognize property right on in-game characters/items, some of them took action preventig E-bay sales. There was a numer of lawsuits by customers about their property right. To my knowledge only one was won - in China. However some MMORPG (Entropy something) took a new approach - they sell in-game items for real money themself. So we can expect the same situation with phone numbers - some providers will objects selling numbers, and some will sell them themself...

  22. Mapping weblog communities on Detecting Patterns in Complex Social Networks · · Score: 5, Interesting
    There are a lot of work going in this direction now. For example here is an article about mapping weblog communities. Abstract: "Websites of a particular class form increasingly complex networks, and new tools are needed to map and understand them. A way of visualizing this complex network is by mapping it. A map highlights which members of the community have similar interests, and reveals the underlying social network. In this paper, we will map a network of websites using Kohonen's self-organizing map (SOM), a neural-net like method generally used for clustering and visualization of complex data sets. The set of websites considered has been the Blogalia weblog hosting site (based at this http URL), a thriving community of around 200 members, created in January 2002. In this paper we show how SOM discovers interesting community features, its relation with other community-discovering algorithms, and the way it highlights the set of communities formed over the network"
