+ - iCloud Powered by Landfill-Fueled Bloom Boxes-> 1

Submitted by 1sockchuck
1sockchuck (826398) writes "Apple's North Carolina data center will tap landfills for biogas, which will then be converted into electricity using fuel cells from Bloom Energy. The 24 "Bloom boxes" will have a capacity of 4.8 megawatts of power, and along with a large solar array, will provide Apple with a significant on-site generation of sustainable energy. Microsoft is also developing biogas-powered data plants where modular data centers will be housed near water treatment plants and landfills. GigaOm has a useful primer on biogas in data centers, as well as video of the new higher capacity Bloom boxes that will support Apple's server farm."

coondoggie writes "NASA noted that as of now its biggest Mars explorer ever will be within 100 days of landing on the surface or the red planet. NASA said at that precise time, the mission has about 119 million miles (191 million kilometers) to go and is closing at a speed of 13,000 mph (21,000 kilometers per hour)."

+ - War against small mail servers? 4

Submitted by

softegg writes "My company hosts our own mail server. We have high-speed business connections through Verizon and Comcast.

Recently, Verizon and Comcast have been blocking port 25 causing our private mail server to stop functioning. Additionally, a lot of ISPs just started blocking any mail coming from any IP in the address block of cable modems.

So we started laundering our mail through a 3rd party service called DNSexit. Now McAfee's MAPS anti-spam system tells us that they are blocking DNSExit for spam.

Essentially, we are finding ourselves increasingly cut off from sending any outgoing mail. What is a small company supposed to do if you want to host your own mail?"

Road Train Completes First Trials In Sweden 345

Posted by samzenpus
from the all-aboard dept.
Hugh Pickens writes "BBC reports technology that links vehicles into 'road trains' that can travel as a semi-autonomous convoy has undergone its first real world tests with trials held on Volvo's test track in Sweden. Researchers believe platoons of cars could be traveling on Europe's roads within a decade cutting fuel use, boosting safety and may even reducing congestion. SARTRE researchers say that around 80% of accidents on the road are due to human error so using professional lead drivers to take the strain on long journeys could, they say, see road accidents fall. They also predict fuel efficiency could improve by as much as 20% if 'vehicle platooning' takes off, with obvious benefits for the environment. 'An automated system is likely to make it safer as it takes away driver error but it would have to be 100% reliable,' says John Franklin 'This kind of system would also require a complete change in motoring culture for drivers to hand over control.'"

Hidden Debug Mode Found In AMD Processors 154

from the sooper-seekrit dept.
An anonymous reader writes "A hidden (and hardware password protected, by means of required special values in processor registers) debug mode has been found in AMD processors, and documented by a reverse engineer called Czernobyl on the RCE Forums community today. It enables powerful hardware debugging features long longed for by reverse engineers, such as hardware data-aware conditional breakpoints, and direct hardware 'page guard'-style breakpoints. And the best part is, it's sitting right there in your processor already, just read the details and off you go with the debugging ninja powers!"

- Other posters have noted/claimed this is a result of high manufacturing costs making this material prohibitive for solar cell production. Could the manufacturing costs of this material be brought down to a point as to make it a good substance for solar cells? How close are we?
- What wavelengths does this material respond too/detect? Could it be modified/designed to image UV/Vis/IR?
- How linear is the response function, or perhaps would it require an exotic calibration procedure to translate photons into radiance?

Thank you for volunteering to answer questions and good luck in your academic endeavors! I wish I was in graduate school now and was positioned to work in this domain.

Black Silicon Used For Surveillance? 56

Posted by CmdrTaco
from the that-sounds-naughty dept.
An anonymous reader writes "For the past decade, 'black silicon' has been touted as a way to make super-sensitive image sensors and ultra-efficient solar cells. That's because the material — silicon wafers treated with sulfur gases and femtosecond laser pulses — is much better at absorbing photons and releasing electrons than conventional silicon, at least over certain wavelengths. In 2008, Harvard spinoff SiOnyx went public with its plans to commercialize black silicon. But what happened to those plans? Today SiOnyx revealed in another exclusive that it has raised new venture financing from Microsoft co-founder Paul Allen and other big investors. It also has formed a key strategic partnership to scale up manufacturing of black silicon — and go after markets in security, surveillance, automotive, consumer devices, and medical imaging."

Chips That Flow With Probabilities, Not Bits 153

Posted by samzenpus
from the new-angle dept.
holy_calamity writes "Boston company Lyric Semiconductor has taken the wraps off a microchip designed for statistical calculations that eschews digital logic. It's still made from silicon transistors. But they are arranged gates that compute with analogue signals representing probabilities, not binary bits. That makes it easier to implement calculations of probabilities, says the company, which has a chip for correcting errors in flash memory claimed to be 30 times smaller than a digital logic-based equivalent."

I do not code in PHP, so please bare with me. What I got was that since the PHP interpreter sees it all as the same code, all the same program, then it is a derivative work. "To the PHP parser, it is all one and the same." If a PHP GPL module presents an API and a PHP non-GPL module uses that API and they run in the same PHP interpreter, what happens?
