  1. Re:motion blur != ghosting on Philips Working on LCD TV Ghosting · · Score: 1


    actually your totally wrong. motion blur is when an object moves so fast our brains aren't able to disinquish it clearly. ghosting is the effect caused when a pixel changes colour slowly and you see a "ghost" image of whats moving. this effect happens on both crt's and lcd's, however it tends to be more pronounced on lcd's. just move your mouse around the screen quickly on your crt and you will see an example. you look like a right idiot now don't you!


    Ever shake your hand really quickly in front of a CRT monitor? I assure you your hand isn't ghosting but rather the CRT is causing your eye to only see the high-contrast hand shape at a handful of points. This is called strobing (like a strobe light.) And it happens in all projected moving media.

    Your definition of motion blur is a bit off too. Motion blur is caused by persistence of vision. Your eye doesn not see objects at one point in time but rather a range of time... in nature there's an infinite number of points we see an object at as it travels during this time range. It's basicly like blending those infinite states together to make a smeared result.

    In film, if you set your shutter speed super fast you'll see super sharp images that don't blend well together (go watch Gladiator again and you'll see it durring the fights.) Strobing is normal, only film and video usually capture motion blur when shooting by leaving the shutter open for a period of time (basicly duplicating your eye's persistence of vision.)

    Computers can't possibly calculate the infine number of points your mouse cursor should be going through as it moves through time. Instead it projects the mouse cursor at the one point at the time a frame is rendered. CRTs will display one mouse cursor per refresh... and monitors refresh many times before your eye stops seeing the persisting image... So your persistence of vision will therefore blend the projected states of your mouse cursor and you see multiple mouse cursors.

    And one more thing... CRTs should have absolutely no ghosting whatsoever as they strobe and the phosphors go dark long before the next image is displayed.

  4. Re:Stop trying to engineer human behavior. on New Way to Make Hydrogen · · Score: 1

    Yeah... there are alternatives for those that happen to land the relatively few jobs out in their suburban areas. But a lot of companies and governments can't afford to buy a bunch of small buildings in the various sprawling areas... they need a lot of folks working under one building. They also like to be near other companies they do business with.

    I know around my neighborhood there are probably only about a hundred or so jobs that pay enough for one to support a family. In fact there's a number of strip malls in my area that really suffer because people don't seem interested in shopping there.

    There's also store competition problems with this. It's very common for similar stores to open in one area. It's good for business and customers as it both fuels competition and increases customers to the various stores. For example, there's two blocks in my town that have no less than 5 music stores. When people go to the music store they know of to buy an instrument, they'll see the other stores and check them out. There's also a string of bars that greatly benefit from their close proximity. They'll often join forces in events and pull a much larger audience that brings more money to each than would if the bars were miles apart. Then there are the businesses that don't have enough demand to be supported by one small area of town but require he whole town's attention.

    Then there's the towns and cities that depend on tourism. Tourism and the benefit to the town would take a major hit in the 'nads. An example would be New Orleans... if it weren't for all the bars, fortune tellers and touristy shops being downtown together, there'd be little reason for folks to go there.

    This will also cause much greater division of wealth in a town. Poor sections of town will be without any economic flow from the richer parts of town. This will increase crime dramaticly. There's also a much higher cost for the local government if they have to deal with fire, schooling, police and transportation is divided even more than it already is.

    Bringing everyone closer to town helps business, crime, quality of public services, a feeling of unity by the town and gives people greater freedom when choosing jobs.... or yeah... and cuts down on pollution overall. Though the concentration of pollution will be increased.

    Depends on what you call a computer and what you call an entertainment center.

    My computer is my web center, DVD player, gaming station, TV, stereo and sometimes my phone... So it's an entertainment center... only hooked up to a monitor instead of a TV.

    I think this 50% chance of being h4x0rD is scare mongering crap. And before you start cracking on the number of installs I've done they've always been because of changing my boot HD, getting a new machine or helping a friend install their copy of Win2k.

  14. MX700 works fine. on Logitech Cordless Desktop LX500 and LX700 Showdown · · Score: 1

    I hate to sound like an advertisment but I'm a very happy customer.

    I've owned a Logitec MX700 and a Logitec wireless keyboard for over a year. The range is really great if you have the reciever away from metal/electronics. I once had to use the computer from about 30 feet away (during a play where the computer controlled some video sequences that were being projected on the wall.) I also use it to control movies from my bed.

    I've had issues with mice cords being just a wee bit too short or dragging the mouse up because of the weight of the cord (really annoying with setups where you need the cursor over a text box to type in it.)

    They even work with a couple walls in the way. Though once I was trying to play some video from a room across the house and it didn't quite cut it. Really, metal and electronic interference are the main issue. Not range so much.

    As far as drivers go, the hardware works just like a regular 3 button mouse/keyboard wihtout drivers. I've used them with Windows 2000* XP, NT4, Knoppix, Mandrake and Slackware. The scroll wheel even works whithout drivers (except in NT as it doesn't support scroll wheels.) I don't have any drivers set up for my keyboard but the volume buttons work under win2k. I don't really have any use for the other special keys. My one complaint about the keyboard is the lack of caps/numlock indicators on the keyboard. My recievers are under my desk and I can't easily see them from my chair. I realize having LEDs sucks batteries (the keyboard goes for a REALLY long time without a battery change... in fact I use it daily and have only needed one replacing since Christmas 2003.

    The recharge unit for the mouse is quite useful. Most cordless mice have low frame rates (and therefore lower precision.) This is especially true when the mouse has been still for a couple seconds. This is done in the name of longer battery life. The rechargable mice have a significantly higher frame rate since the user doesn't need the battery to last a couple months.

    First off, evolution is an observation, not a theory. We can see it happen and people have been harnessing its power in farming and making better pets for ages. We also see it happening all the time. Hell, it's why you can get the flu every year. The bacteria keep changing.

    Secondly, evolution does not state that bacteria + mutations + time = humans. It's more like death of organisms that failed to pass certain genes + organisms that successfully passed different genes + mutations + time = different species.

    Then you can take it farther with things like "change in environment requiring change in species for survival" and "species competition"

    You mention Mendel... Is Mendel's work not more evidence of evolution? It's clear that if Mendel changes the requirements for an organism to pass its genes and an organism fails to meet those requirements, the organism fails to pass its genes while the ones who successfully met the requirements passed their genes and still have their genetic material in the world. These requirements can be anything from "Having a pleasing flower color so that human that's controling its ability to pass genes" to "being able to outrun that large predator that's going to get in the way of gene passing."

    If Mendel's work is gold, but ignore mutation then you'll end up with genes being kicked out and none being created... meaning life would have died out a very, very long time ago.
