Comment Not likely to happen... (Score 1) 179

There might be some small attempts to do this, but it will be so vilified that no developed nation would be able to do it to any great degree. Automated free roving killing machines will be FAR easier in the near future and politically acceptable as well, as you are not dehumanizing/exploiting your own citizens to achieve your goals. Plus I don't care how outlandish your mutant enhancements are short of Wolverine regenerative powers, MACHINES, BULLETS and BOMBS will splatter you just like any other flesh based entity.

The future is automated or remote controlled killing machines -- bank on it.

Comment Re:Why I doubt driverless cars will ever happen (Score 1) 604

(dang, my first post was AC)

Likely the car will not self-drive if the sensors are not clear. A whole windshield will not be needed for the sensors, their port/lenses will be small and likely they will largely self-clear of ice and water. The occasional leaf may cause a warning light and instruct you to clear it from the sensor. Redundant sensors will allow safe opperation should some fail while in drive, but will probably demand rider/driver intervention.

Comment Keep at PS3, get Move and Wonderbook. (Score 1) 267

I got a PS3 early, but not $600 bleeding edge early. 6 months $450 with 13 free Blu-Rays early.

We use it mostly for watching Blu-Rays in a home theater system. We have not gotten many games for our daughter and have tried to steer her to the more puzzle solving or physically active ones. She has not been much of a gamer, but the Playstation Move works good enough (though expect to do a lot of fiddling every time to get the camera and wands working just right) and they do tend to her favorite games.

It has been a good investment, though mostly we use it for entertaining when we have company. We hadn't been firing it up more than about once a week.

That has all changed for my Daughter, who is age 9 now. She is an avid Harry Potter fan, has read all the books. I bought her the Wonderbook with Harry Potter for here birthday last week and she is addicted. To be honest I was underwhelmed by the Blue-Bar coded Wonderbook when it arrived a week ago, but when used with the Move system this thing finally offers an augmented reality home run of entertainment for kids. PS3 owners shouldn't have to look sheepish when taking to Wii or Kinect users if you have one of these. I always preferred the more accurate Move tracking, but lamented the Party appeal of the Wii and Kinect. The Wonderbook does not solve the Party solution, but it does make a solid rejuvenation of our game system for our daughter.

Someone should make a bar-coded Move dance pad version of DDR (perhaps there is one I'm unaware of) instead of the flaky DDR pads we have tried to use. This would be a more Kinect like experience and potentially more accurate. With bar-coded props Sony could create a new genre of gaming. How-about bar coded steering wheels or space ship controls, fold out cardboard spaceship bridges that morph into Enterprise like helms on-screen? The Wonderbook definitely shows this is possible.

In any event all the next gen systems are coming out next Christmas, milk another year and half from the system you have now and get what ever seems best come the summer of 2014. I'll probably get an Xbox 720 with next gen Kinect then, you know, for parties.

Comment Re:While on the other hand do see it working well (Score 5, Insightful) 388

It seems odd to me that there should be such a Luddite tone here on Slashdot, and an egotistic assumption that humans will always be better at these tasks for the foreseeable future. I see several problems with your lane marking example. 1. If lane markings are so bad humans cannot easily discriminate them, then this should be addressed ASAP autonomous vehicles or not. 2. You seem to assume the self driving car will have no other lane confirmation information other than lane markings from some camera with human eye like contrast discrimination when in actuality, having taken the recent Stanford AI course, they will use multiple input sources and cameras to determine proper lane usage including statistical probability based on previous lane markings, the sides of the road, GPS, LIDAR, RADAR, and placement and movement of other nearby vehicle (and of the latter it will place much more avoidance weight). With Google’s quarter of a million miles already autonomously driven I would assume they often navigated areas with less than ideal lane markings (else we would be hear the hilarious situations the Google cars where constantly getting themselves into).

Yes people will balk at first, but this really is a task humans are REALLY bad at. We may be wonderful at discriminating a dog from a cat or recognizing a pizzeria from the pizza shaped sign, but the self driving car will be hugely better at determining that there is an object at of size X at distance X traveling Z miles per hour towards us. It doesn’t need to understand what every object on the road or side of the road is to operate, it won’t be distracted by video billboards or scantily clad persons of the opposite sex – it is just obsessively crunching data on position and moving object hazards all the while confirming the road ahead is true drivable pavement.

This is a hugely complicated problem, but it is well constrained with clear rules. There is nothing new about driving the self driving car needs to figure out each time. Until streets are better designed for autonomous vehicles they may be overly cautious, but I doubt hazardous, and as streets become optimized for self driving vehicles and as the vehicles themselves improve, they will be able to tear around at incredible speeds safely – if we decided we wanted to let them off the leash so to speak.

Comment Re:Same as 120/240Hz HDTVs, I can't stand it (Score 1) 607

Wow, sucks to be you I guess or rather those of us who would like to have our experiences more immersive and realistic should shut up an never change things. You probably would much rather enjoy the Keystone Cops at 12fps as well. As far as all this crap about 120hz and 240hz framerates looking sooooo bad, this is almost always because there is an algorithm trying interpolate 24fps or 30fps to something higher. The early days of HDTV were especially excruciating when trying to take 480i content to 720p or 180p. If the framerate were high to start with (and no interleaving) there would be no issue. Most (all?) sets with upconverting to 120 or 240 can have it turned off. Please do so and quit whining.

With higher framerates producers could use faster pans which totally suck at 24fps. 3D will also look much better. When scenes are in motion in 3D the lower framerate causes the target image to be different for each eye and the 3D effect breaks down -- sometimes painfully so, this maybe at least one reason so many complain that 3D causes headaches.

Comment Pointless (and wrong) exercise in Statistics (Score 3, Insightful) 344

Thousands of Exo-planets discovered. Viking’s life detection experiments are being reconsidered. Life has been found to have started very early in Earth’s evolution. Various Extremophiles discovered. For the last twenty years the evidence keeps tipping in favor of extraterrestrial life being more and more likely. That we haven’t yet discovered said life says more about our commitment to doing so than its likely-hood.

Sadly this article will be linked to a thousand times by the ID crowd shouting we need to stop wasting all this money looking for ET and realize how special and God chosen we are.

I’d also add Bayesian analysis sucks when it comes to these all or nothing analysis with such a small sample size. Bayesian analysis can be used to say we have approximately 50-100 years of civilization left. HOWEVER the same analysis 200 years ago would have given roughly the same result. These kinds of statistics mean nothing until you have a large data set that is properly categorized. We don’t even know for certainty our next nearest planetary neighbor is lifeless. Finding life on Mars would sudden explode Bayesian stats to near certainty that life is everywhere.

Comment Higher Frame Rate Please (Score 1) 404

I do not own a 3D TV (yet), but I have a few strong opinions about 3D.

At sometime in the future I anticipate getting 3D. That said most 3D to date has been bad or unneeded. I could go on for some time about bad 3D, but even good 3D is still deficient at its current frame rate ESPECIALLY with LCD shutter glasses. If you watch fast motion scenes like those in sports with LCD glasses you see the most annoying stutter artifact from both eyes not seeing that same object at the same position in space at the same time. In low motion shots this is less annoying, but even with polarized glasses and seeing two images at the same time 3D seems to exaggerate stuttering. I have heard that the Avatar sequel will use 48 or 60fps 3D. Perhaps we will finally see true 3D nirvana when it arrives (plot not withstanding).

Even without 3D I would love to see frame rates pumped up. Despite what I hear over and over again about a “Movie Feel” at 24fps, I want as close to reality as possible for optimal suspension of disbelief. One fine note about 24fps and the “Movie Feel” there are lots of panning effects movie producers would probably use to enhance movies if the stutter from rapid panning at 24fps didn’t look so God awful.

Comment Re:Fermi Paradox (Score 3, Interesting) 294

I'm not sure why you want to shout Fermi Paradox, it is not an answer but a question.

20 years or more ago we could have speculated that planetary systems were rare, thus life had few places to evolve on and that could have been a possible solution to the Fermi Paradox -- finding so many worlds deepens the Fermi Paradox.

Let us hope Fred Saberhagen doesn't have the correct answer to the question with his Berserker series of novels.

Comment Re:100 billion likely way too low (Score 2) 294

So we find one or two possibly Earth like planets. Likely the other KOIs also had many near Earths that we missed. Eventually we might get some bound on the percentage of systems with Earth like planets, but listening at these few KOIs is like like looking under a street lamp for the keys you lost half a block away because the light is better.

With 200-400 Billion suns to survey and most having Planets and probably 10-50% have some planets in its equivalent of the Goldie-Locks zone, then you are far better of getting on with a broad general survey of thousands or millions (or ideally billions) of suns. I fear concentrating on these particular KOIs will dilute more productive SETI searches. I fear the general public is under the assumption that we were lucky to find these near-Earths because they are rare when the opposite is almost certainly true.

Comment 100 billion likely way too low (Score 5, Interesting) 294

100 Billion is likely too low. Based on a survey of close suns using Doppler shift indicated at least 50% had planetary systems of some sort. I think the future will boost this percentage to 90% or better, probably virtually all suns have some kind of orbiting object that could be termed a planet. Depending on where you draw the line on size this makes for probably more than 2 Trillion alien worlds in the Milky Way alone (which is estimated to have 200-400 billion suns).

As for examining Kepler Objects of Interest (KOIs) more closely it seems there is little point to single them out. So what if we know they have planets -- everywhere you could point a radio dish there are planets. I am a big supporter of SETI and this is all good news for SETI, but it doesn't do anything to narrow the search.

Comment Re:Don't confuse Duration with Capacity (Score 1) 378

As mentioned I did a little Googling for other articles, from PC Magazine

"We have found a way to extend a new lithium-ion battery's charge life by 10 times," said Harold H. Kung, lead author of the paper, in a statement released by the university. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today."

Which I would interpret as meaning two batteries with the same capacities have vastly different capacities after 150 recharge cycles. 10x would be too huge an increase in charge density to be believed. Keep in mind we are getting lay person summaries in these articles and it is striking that NONE of them mention huge range improvements for this like Automobiles, but do mention things like Charge retention over a week for cell phones which I interpret as meaning better standby charge holding rather than talking on the phone for a week.

Comment Don't confuse Duration with Capacity (Score 5, Informative) 378

Having read the article (*gasp*) as well as a few others it seems these batteries do NOT hold 10x more power. They degrade 10x slower on on drain/recharge cycles and can be charged 10x faster. BUT this is not the same as having 10x more POWER per cycle. Gonna have to wait some more before you get an cheap electric car that can go 500 miles before charging (though charging 10x faster is nice).
