First off, if we cut through the usual dismal quality of scientific reporting, what they made is a photodetector, not an image sensor. It detects single events rather than capture an image. The sensitivity of the detector is not the same as quantum efficiency. The sensitivity they mention here includes a "photogain" by virtue of the detector operating more or less as a light-controlled amplifier. It takes electrical input energy and simply amplifies it based on incident light. That can create a flow of many more electrons than incident photons. The same thing can possibly be also done by introducing a gain in the conventional image sensor electronics too, but having this photogain right inside the sensor should theoretically lead to better noise performance. So we would expect the paper to quantify the noise characteristics, but it is woefully sparse on the noise details - which leads me to suspect this is yet another "invention" that is never going to see the light of day.
Wrong on the India farmers bit. Here is an extract from a Wikipedia article -
There have been claims of genetically-modified (GM) seeds (such as Bt cotton) being responsible for the farmer suicides.[25][26][27][28] A short documentary by Frontline (U.S. TV series) suggested that farmers using GM seeds promoted by Cargill and Monsanto have led to rising debts and forced some into the equivalent of indentured servitude to the moneylenders.[29]
A report released by the International Food Policy Research Institute in October 2008 provided evidence that the introduction of Bt cotton was not a major factor in farmer suicides in India.[30] It argues that the suicides predate the introduction of the cotton in 2002 and has been fairly consistent since 1997.[30][31] Other studies also suggest the increase in farmer suicides is due to a combination of various socio-economic factors.[32] These include debt, the difficulty of farming semi-arid regions, poor agricultural income, absence of alternative income opportunities, the downturn in the urban economy forcing non-farmers into farming, and the absence of suitable counseling services.[32][33]
No they aren't safe. In the case of sunlight, eyes see it pretty strongly and the pupils contract to cut down the amount of light that strikes the retina thus protecting it. In case of UV, there is a chance he may not see a part of the spectrum so his pupils remain dilated letting in dangerous amounts of UV light. Same reason it is advised to never look at an eclipse with unprotected eyes.
Syncs in background for me, I dont have this issue. If it happens only when you are writing an email, then you probably configured your drafts to be saved to a (slow) IMAP folder?
Space programs do not drive the fundamental tech needed for smartphones - they may contribute to advancing ruggedness and reliability of electronics, but never miniaturization or cost reduction. NASA would prefer to use a tried and tested FPGA that is 20 years old, in a 1um radiation hardened process, rather than the latest 40nm Nvdia/Qualcomm processors, leave alone driving their development.

I agree. MS has become increasingly security savvy to protect their main business - the OS and the Office applications that go on it. The Vista/Win7 permissions model, MS Anti-malware updates, MS Security Essentials, Driver signing, bug bounties, are all examples of MS efforts to up the security. These comments are along expected lines from MS in this age. (And no, I use more Linux than Windows, but credit to be given where credit is due).
Photons? For a RADIO telescope?? Yes, quite a while since your astro classes.
The SNR you quote, which improves as square root of the collected radiation (radio waves), is voltage SNR. In terms of power, you still get a 9dB SNR improvement for 3 times the collected radio waves, and in these electronics, it is electric power which is the ultimately used. However, the improvement factor should again be raised to power 1/3 to get distance, since the amount of signal power collected by an aperture, after spherical dispersion from a star, drops as the third power of the star's distance.
So.. (25/9)^(1/3) = 1.4 times.
What should be the absolute heart of slashdot, two new releases of Linux, sporting different styles, is getting some 30 posts for BOTH distros combined,
Everybody else is busy writing up the story to submit.
Apple had acknowledged to Congress last year only that "cell tower and Wi-Fi access point information" is "intermittently" collected and "transmitted to Apple" every 12 hours.
Citation? I don't doubt you, but just because you type it does not make it true. Especially in the auspices of someone who decries fanboi-ism, I'd expect to see an avoision of even the appearance of impropriety in fact-reporting.

Rogues, rapscallions and rascals
Thursday September 23, 2010
Carfolio.com has been collecting and collating automotive technical data for many years, before actually having a website or even an internet-connected computer. Realising that there would be interest in this database, I decided to put my data up online in a very useful and functional way. It has always and will always be free for anyone to utilise. Some people, however, have decided to crawl the site and put all the data into their own database and resell and republish the information without attribution, credit or acknowledgement. Some go as far as to add 10mm to the basic dimensions so as to try and disguise their actions... I find that extremely bizarre, as part of the whole idea behind Carfolio.com is to get as many errors found and corrected as possible, and to that end I have always encouraged feedback and dialogue about the specifications. Factual errors are always corrected if sufficient sources are supplied.
So as to ensure the best possible quality of data for Carfolio.com users, here is a list of the sites currently known to be using the data without attribution. I will not give them a link, of course, as that will unduly increase their search engine ranking.
autofiles dot org
carspector dot com
data4car dot com
carocean dot co dot uk (and de, es, pl, it, fr)
scorpiocars dot net
ukmotorist dot co dot uk
getcarspecs dot com
Please be wary of the data from these sites as they are definitely not updated and almost certainly have introduced additional errors when crawling or attempting to obfuscate the source of the data.
FF4 crashes about 10 times everyday for me too. Just found it may be related to the Testpilot extension that comes installed by default (look up the linked bug reports in your about:crashes page).
Where did you pull that out from? Mineral oil density is 0.8gm/cc, water is 1gm/cc. Way more?? http://en.wikipedia.org/wiki/Mineral_oil
Condensed water as a result indeed does sink to the bottom.
An interesting account of a mineral oil cooled PC here - with updates over a period of 3 years! It also discussed the problem of condensed water sinking to the bottom.

Couldn't have said it better. IT today is only focused on security and ease of administration, forgetting about the flip side of facilitating business at the same time.

Sanest comment on this post yet! Wonder why it is not marked +5 insightful yet..

Still waiting for the second word...
Why isn't this in Ask Slashdot section??

Somebody please mod this FB shill a troll...
So why not just publish it, making it prior art? Or maybe what you want are Trade Secrets?

It is supposed to happen only if location based services is toggled on and an app that requires location data is running. http://www.wired.com/images_blogs/gadgetlab/2011/04/applemarkeybarton7-12-10.pdf , Page 7.
