Comment Re:Talk about losing customers (Score 0) 439

so I am scratching head as to why apple patented this. If they ever used it they would lose whatcustomers they have.

Apple fans are pretty devout. A bet Apple is betting enough of them will stick around even with obtrusive ads. And another large segment of Apple users are technologically challenged, so the energy of learning to use a blackberry or droid won't be outweighed by the annoying ads. Personally, I'd be iRate.

I find it unimaginable that people would attempt to implement a technology that is not fully understood. Doing so will eventually yield unexpected results or at the very least, results that cannot be explained.

Except that occasionally building a working model is a useful step to understanding it. I'm happy that Edward Jenner in 1796 started infecting people with cow pox as a way to prevent small pox even though he didn't fully understand why it worked.

Comment Anyone know about bees? (Score 5, Interesting) 90

The researchers drew their algorithm from neural circuits attuned to side-to-side yaw, but O’Carroll said the same types of equations are probably used in computing other optical flows, such as those produced by moving forward and backwards through three-dimensional space.

I vaguely remember seeing a study that examined how bees travel without hitting anything but using very few neurons. Something about the relative size change of objects between eyes. They tested this by putting bees in a clear tunne with patterns on belts on the right and left walls. By changing the speed of the belts, the bees would ram into the walls, but as long as the belts were moving at the same speed, the bees were fine. Is this ringing a bell for anyone else?

There once was a man who was given a small box by a woman. The was entirely closed except for a hand-sized hole at one end which was covered with a black cloth so no one could see inside. "Put your hand inside," said the woman. The man put his hand inside and immediately felt a sharp pain. He removed his hand. "Put it inside again," said the woman. "It will hurt," said the man. "That must have been a fluke. Trust me." The man did as he was told and was met by a sharp pain. He again removed his hand. "Put it inside again," said the woman. "No," said the man. "The last two times it has hurt my had. You lied. I will not do it." The woman took her box and walked off.

Perhaps, oh Marin Spammer, the one who needs to learn the lesson is NOT the one with the problem. Give a user a PC and you will fix the PC for life. Beat the user to death with a PC and you will never be bothered again.

From the folds of her gown, she lifted a green metal cube about fifteen centimeters on a side. She turned it and Paul saw that one side was open - black and oddly frightening. Paul slowly put his hand into the box. He first felt a sense of cold as the blackness closed around his hand, then slick metal against his fingers and a prickling as though his hand were asleep...

"What's in the box?"

"Pain." He felt increased tingling in his hand, pressed his lips tightly together. How could this be a test? he wondered. The tingling became an itch... The itch became the faintest burning... It mounted slowly: heat upon heat upon heat... . The burning! The burning! He thought he could feel skin curling black on that agonized hand, the flesh crisping and dropping away until only charred bones remained.

Remind me again what Muad'Dib has to do with a family's computer problems?

Comment Like Military Intelligence (Score 1) 383

The advantage of Twitter is that it can offer raw data when there are quickly developing events. One of the problems with that is that it hasn't been vetted. Questions like "How trustworthy is the source?" or "Do these reports together indicate a trend?" haven't been asked. That's the job of CNN's reporters. And that's what news articles are for. But I don't think you can complain about having access to the raw data feed. So there are people whose intelligence rivals inanimate objects with the ability to upload their observations and thoughts; if you don't want that, don't use Twitter.

Military Intelligence is the same way. The data can be phone calls from informants or reconnaissance photos, but it still needs vetting. As long as leadership remembers they're looking at unprocessed data, there's nothing wrong with them accessing the raw feed. Of course, getting them to remember that can be tricky, but that's another issue.
