Electric Stimulation Could Help You Control Your Dreams 138

sciencehabit (1205606) writes "A new study suggests that mild current applied to the scalp while sleeping can help people become aware of, and even control, their dreams—a phenomenon called lucid dreaming. Researchers recruited 27 men and women to spend several nights in a German sleep lab. After the volunteers had plunged into REM sleep, a state in which people are unable to move and the most vividly recalled dreams occur, researchers applied electrical current to their skulls near the forehead and temples. This boosted neural activity in the frontotemporal cortex, a brain region associated with conscious self-awareness, which normally gets tamped down during REM. Researchers then woke the participants and asked them to detail any dreams they could remember. People who had received 40 Hz of current were lucid in more than 70% of their reported dreams. The researchers suggest that the technique could potentially be used to help people who suffer from chronic nightmares."

I don't think market cap is a good measure of size. If it were, then during the dotcom boom various online pet food suppliers, etc, which had barely any assets, employees or customers, would have counted as 'bigger' than more boring companies with a much greater footprint in the real world. Similarly, a large company may head towards bankruptcy and as it does so its market cap heads towards zero. But even if it is sold for a nominal price of one dollar, it is still a big company by any reasonable measure.

There's no issue getting 3840x2160 resolution with any even half-recent video card. I drive a T221 (3840x2400) from a five year old Dell laptop; these displays first appeared a decade and a half ago when PCs were much slower than today. Admittedly, if your new monitor takes Displayport you will need a video card capable of outputting that. Now, if you want to play games at 3840x2160 at 60Hz refresh, you're going to need some pretty serious hardware. But that has nothing to do with using the display for programming or office tasks. 30Hz refresh is quite comfortable for that.

Why on earth would you choose to base your product (something that presumably companies will use for many, many years) on something that will have no security support in just 4 months?

You wouldn't. You based it on something that would be supported for several years when you made the decision back in 2006. It's just that schedules being as they are, it has taken that long to develop the product and get it to market.

In the land of dinosaurs, where Big Companies do Stupid Things, it is fairly common for new products to be launched and then the whole platform end-of-lifed soon after. It's nobody's fault in particular, just how decisions get made.

There should be some way to sell computing power to cloud customers. Like a live-CD Linux distribution you boot, and it connects to some online exchange to see if anyone wants to rent virtual machines. If nobody is offering enough cash to cover your power costs then it sends the machine to sleep. However, CPU power efficiency improves fast enough that even if the hardware is free and sitting idle in your garage, you still might not be competitive with specialist cloud providers. (Then there are the inevitable issues about data privacy, reliability etc.)

Panasonic's Toughbook rugged laptops have colour transflective displays. But the colours start looking washed out in bright sunlight, so perhaps the transflective part is black and white only somehow. And the readability in direct sunlight is not quite what the marketing wants you to believe - you're still better off finding some shade.

Comment Re:Unusable aspect ratio (Score 1) 94

Yeah I'm just talking about the aspect ratio and resolution. Another good example would be the 'retina' Macbook Pros - they are also 16:10 though not quite such a high number of pixels (the 15" has 3/4 as many pixels on both axes as the T221). But since you mention it, I wouldn't agree that a slow refresh rate or poor colour gamut rules out 99% of uses. Probably only about 5% of users require colour accuracy; the T221 is no worse than most monitors, photos look pretty good on it. (I use a wide-gamut monitor too but for day-to-day use it makes no difference.) Even a 24Hz refresh rate is enough for text-based work such as programming, office apps or web browsing. So don't knock it till you have tried it!
