  1. Re:I've got an easier way on Sandia Studies Botnets In 1M OS Digital Petri Dish · · Score: 1

    If they've set up this mini-internet and have set up this botnet, then the easiest way to understand its behavior would be to look at the source code

    By that logic, by dissecting a single neuron you would be able to understand how a human brain works. Unfortunately, human brains have a wide number of different neurons, each of which serve a separate purpose. While the DNA may contain the instructions to build a brain, it's not possible to deduce what the final layout will be.

    Similarly, in a botnet, each host will have a seperate purpose, some machines will be dedicated to sending spam, or ping packets, while other machines will be command and control centers which communicate directly with the attacker. Command instructions will be encrypted and some botnets actually randomly change command and control centers to avoid detection. The only way to see the final layout is to run a full network simulation.

    Microwave ovens have a cage (the sheet of metal with all the small holes) that reflects the microwave energy back towards the food.

    Whenever I have the wi-fi network unit on my laptop (or a GPRS/3G modem), I do feel a certain dryness in my eyes, and a slight metallic taste on the underside of my tongue.

    Most of the safety innovations for private cars came from the racing car industry - roll bar cages, seat belts, crumple zones, safety glass. Roll bar cages and crumple zones and safety glass have been into train carriages as well.

  4. Re:bs science as usual- and a waste of time/effort on Laser Ignition May Replace the Spark Plug · · Score: 1

    All they are doing is replacing the spark plug electrodes which generate a high enough potential to create a high temperature spark to ignite the fuel mix, with a laser beam and assembly that creates enough heat to ignite the fuel mix.

    It will be like having a CD/DVD laser in each spark plug, rather than that just two metal pins.

  5. Re:Shockingly sensible on Med Students Get Training In Second Life Hospitals · · Score: 2, Interesting

    To get the dummies to physically appear to react to the medical conditions that they are simulating requires special effects technology. To simulate the physical behavior in a virtual world just requires some software programming.

    Or about stopping the auto-update. I use yum to install firefox automatically, then about 4 hours later I get message telling me that "Congratulations, you have firefox 3.0.11 installed", which breaks Google Streetview - it just remains black and no options actually appear in the Preferences->Clear Private Data popup. Reinstall Firefox using yum install, Google Streetview works again, and the cycle repeats.

  8. Re:"Scoop" ? on Has NASA Found the Lost Moon Tapes? · · Score: 1

    They need "eye candy" for the public to appreciate what they are doing. A graph of the chemical composition of moon rocks will be meaningless to most of the public. A multi-color cartographic map of the moon with different rock compositions in different colors looks cool on a teenagers bedroom wall. But just about everyone can appreciate high resolution images on a webpage or Google Moon.

    so once the government concerned becomes aware that the receiver is hostile to them they can follow that social network back. It's not just Google who can work out probable friends of yours automatically.

    In which case, all communication must be done using chain letters or multi-casting, so that the intended recepient is never unique.

  10. Re:Bullshit from the "industry pundits" on Social Networks As Gaming Platforms · · Score: 2, Informative

    These "social network" games are different from traditional PC or console games, in that you are allocated a fixed number of action points and health points each day, which restrict you to one or two moves. It might be fighting another character or doing a mission. In each case there is an element of chance which rewards you with money and/or experience points. Your AP and HP recharge each day. As you gain experience you get more AP and HP. Some games require you to have a "horde", or allow you to join an "alliance". Others disapprove of this and will punish players for doing so. The linear nature of such games is broken by having loops and forks and portals in the mission paths, which allow different paths to be selected.

  11. Re:Wait... on Passengers Cheat Flu Scan With Fever Reducers · · Score: 1

    Maybe they need a better detection system - if biosensor "sniffers" can detect the molecules given off by certain cancers, perhaps it is possible to detect the molecules associated with the flu virus.

    Thinking about it some more, even with a wireless joystick players still had to sit next to the old consoles in order to swap cartridges, select and restart a game. Only once additional buttons were added was it possible to really play games.

  14. Starting from scratch... on Why Isn't the US Government Funding Research? · · Score: 1

    If you were to create a research department from scratch, you would first have to procure land, office buildings, equipment, furniture, research directors, PA's, managers, engineers, and technicians. All of this is going to take money (lawyers, recruiters, adverts). By buying a company, all of this has been done already.

    Unfortunately, creationists have created an escape condition from that logical argument. They accept that there are small changes that occur between every generation, but that these are small changes that cancel out and do not add up to the major changes that are are claimed to have happened (assuming they don't believe the world was created 6000 years ago).

  20. Re:Search Technology on Could a Meteor Have Brought Down Air France 447? · · Score: 1

    We did that with the search for Steve Fossett. High resolution images of the Californian desert within the distance that his plane could fly were taken, sliced up and posted on Amazon's Mechanical Turk (much like tiles from a console game). These numbered literally in a million or so.

    The results were that dozens of old wrecks were found, but not Steve Fossett's plane. His plane was found when a mountain hill climber was walking along a trail at around 10,000 feet and came across his plane. The plane had continued at the preset altitude until it hit the mountain.

    Some of the suggestions from helpers - the search could have been automated by comparing before and after photographs of the landscape. That would have helped eliminate the majority of the recognition work.

    Even without engines, as long as the plane remains level,it could still glide although for only a number of minutes. The "glide ratio" for a large plane is somewhere between 10.0 and 20.0 . Some planes which have flown
    through volcanic ash clouds or had fuel pump failures have been able to glide for hundreds of miles from 35,000
    feet.

    I think astrophysics is like that - I once went into a university bookstore to buy some recommended textbooks. On the top of the discount book table was a really impressive looking book with a some wireframe graphics on the front page. It was a summary of all the research carried out on the mathematical theory of black holes over 10 years (the size of two PC keyboards back to back). It was being sold at a discount because all the research was now out of date.

  23. Re:ps3 exclusive on Heavy Rain Gameplay Explained · · Score: 3, Interesting

    The idea is that a platform exclusive game would be sold together with a console system and controllers as part of a discount deal, or even as a launch title. In return for the developer make the title exclusive to the system, they would get additional technical support in order to demonstrate the advanced features of that system. The idea is that shoppers would see TV adverts, walk past a game store, see a large box with the colorful screenshots of the game and want to buy the game. (Examples are like Combat/Air Sea Battle with the Atari 2600), Sonic the Hedgehog with the Sega system, and Super Mario 64 with the Ultra 64.

    If a developer aims to target for a large number of different systems, the time spent on cross-development will usually take away time spent on code optimisation and adding extra detail and features.

    I thought of the short sci-fi story "The Giant Killers" which was about a small team of soldiers trying to capture the AI unit of an automated tank. They had a Heimdall system (backpack optical/radar system with speech recognition/ability) to help protect them against night-time missile/biological attacks. There were spybirds which could perch on tree branches and also circle at an altitude looking for targets, then they would inform the other systems and launch an attack themselves.

    The BIOS (including the boot-selection page) is password protected.

    Usually there is a DIP switch on the motherboard to bypass the BIOS password. For laptops it is accessible by removing one of the underside panels. For desktops it will require removing a side-panel or two. Slightly less effort than replacing the batteries on a remote control.
