  1. Practical Application? on "Microsaccades" Help To Refresh Your Field of View · · Score: 1

    Though knowing what part of the brain is responsible for this feat is a great revelation, it has been known that eye movement helps us to filter the noise and false images generated by our all too imperfect visual system.

    With movement our brain tests repeatedly our rods and cones to verify that what they see is actually in front of us and not due to various things like the blood flowing through our retina, or the attenuation of a single or group of rods or cones with respect to others. After such eye movements, if a rod or cone still registers the same value then the brain can filter it out as not being real, or at least part of a smooth blank space (which probably gets ignored as well).

    I am wondering if this can be applied to modern cameras, which seem to have problems with image noise. Instead of employing small sensor movements to reduce camera shake, perhaps they could be used to move the sensor in a predetermined path, one in which the final image could be calculated from. It would seem that if such a calculation of the resultant image could be done, then a much better image could be the result.

  2. I drink stuff with splenda on The Soda Situation - Succulent Drinks w/o the Sweets? · · Score: 1

    My favorite caffinated, carbonated soft drinks are Diet RC Cola and Diet Big Red.

    Both have splenda instead of Aspertame.

    Yea, RC cola is still being sold. I like it much better than Diet Coke with splenda. I buy that sometimes too when the local store is out of RC (they don't give RC much shelf space, and I think a lot of other people around here like it too). With DCwS the Coke people seemed to have rushed it to market without optimizing the taste first.

    As for Diet Big Red. That's an acquired taste, but very addicting once your used to it. By the way, try mixing in some Napoleon brandy with Big Red (no, I not suggesting this for during work--I mean at home when partying). It has a strange synergistic effect together.

    Coffee I usually only drink in the winter. It's too hot here in Texas to be drinking anything hot. I drink a lot of tea though (or as you northeners call it "iced tea"--like you would serve it any other way).

    In addition to making tea myself, I also like Arizona Diet Green Tea. That too has splenda. It can be very economical when bought in gallon jugs at Walgreens or CVS.

  3. Ion engines on NASA talking again about manned mission to Mars · · Score: 1
    I am a systems analyst and work at JSC and I helped an engineer convert some animations to Quicktime of the Solar Electric (Ion) Propulsion system ("tug" as mentioned in the article, SEP as we know it, or as we sometimes refer to it as the "batwing" from the way it looks).

    Kinda interesting, the SEP slowly spirals up the Mars Transfer Vehicle from a circular orbit to a highly elliptical, high energy orbit. The orbit stays above ~1000mi limit at closest approach until the very end. This is to avoid the space debris at these lower levels. The orbit is then tightened down into this area to rendezvous with the crew taxi.

    The crew taxi on this model was a X-38 with an attached booster engine. For those who don't know, the X-38 is the crew return vehicle for the space station. It's a small lifting body shuttle-like vehicle. It has been designed to fit on top of an Airane rocket. Nice to see it reused here.

  4. We don't need to waste money... on NASA talking again about manned mission to Mars · · Score: 1

    In addition to all the mylar, integrated ciruits, etc. listed above, some of the biggest things to come from the space program has been in the field of medicine. Anything from tools like medical imaging, air tables for burn victums, & various medical sensors, to basic understanding of many biological functions. All came from all that poking and prodding they did to the astronauts for the moon missions. When your trying to solve how to keep humans in space for extended peroids of time you tend to learn a lot.

  5. Shouldn't it be more this way. on Review:The Story about Ping · · Score: 1
    The boat captain of the wise-eyed boat, Captain Torvalds wanting to see if his friend Captain Stallman was on the river, creates a duck out of mid-air. He tags the duck with a collar around his neck with Stallmans name and then sets the duck on the river. The duck almost immediately materializes on each and every boat on the river (or at least up to any locks).

    On each boat, the boat's captain sees his copy of the duck and looks at its collar. Now the boat captains on this river are all bloodthirsty. All boat captains who don't recognize the duck, immediately kill it.

    If Captain Stallman is on that section of the river, and he sees the duck with the collar with his name on it, he accepts the duck with a big hug. He feeds the duck, then retags it with Captain Torvalds name and puts the duck back on the river.

    The duck once again mysteriously shows up on everyone's boat. Where in we get another bloodbath of ducks being killed. Captain Torvalds sees however that his duck has returned. He is happy to know his friend Captain Stallman is on the river. He then kills the duck anyway, knowing it has served its purpose.

    Now if Captain Stallman and Captain Torvalds are on two different sections of rivers separated by a lock, the lockmaster will help out and transport the duck between the two sections of river, but he never bothers to feed the duck. Just like on the first river section, the duck multiplies on each boat (and other locks). More blood is spilled. Other locks will let the duck pass, but after awhile, if the duck can't find Captain Stallman, the duck dies of starvation.

    The end.

    :-P

  6. Economics, Domination, USB? on Apple to charge Licensing Fees for FireWire · · Score: 1
    I personally think, 10 cents or a quarter would have been a better price. This is a matter of economics. The higher the price may mean more perhipheral companies will choose to use USB ports for certain items.

    Over time Firewire could have dominated all other ports. Mass production would have brought down the price to that of USB ports, and considering that Firewire is faster, who would need USB or any other port. We would have the simplicity of one Firewire port for everything. But with the extra royalty fee, this will probally not be the case. And it will probally result in Intel comming out with Advanced USB in a few years.

    BTW, does anyone know if Intel charges a royalty for USB?
