Photos: Turning food waste into energy
August 31st, 2009 | 
Author: Food waste is one of the least recycled materials in municipal solid waste systems, according to the Environmental Protection Agency. But at least one organization in the San Francisco Bay Area is trying to change that.
The East Bay Municipal Utility District is experimenting with innovative techniques to convert raw food waste into usable energy, taking some of the massive amounts of food waste generated by local restaurants and using it to power its operations in Oakland, Calif.
In 2007, EBMUD was awarded a $50,000 grant from the EPA as part of the Resource Recovery Program to explore new ways of digesting food waste to produce methane gas.
Today, the facility is home to a million-dollar facility that is generating usable methane and producing nearly 100 percent of the power needed to operate the regional wastewater treatment operation.

Mac OS Snow Leopard: Great news for Windows 7, too
OS X 10.6 includes Boot Camp 3.0, a new collection of software drivers that make Windows run much better on Mac hardware.

Every time I see the “I’m a Mac/I’m a PC” ads on TV, I can’t help but wonder, “Why not both?” And it has never been a better time for that.
It’s been a three weeks since I first got my hands on Apple’s new Mac OS X 10.6 Snow Leopard. (If anything, this means lots of hard work benchmark testing the product while trying to keep my mouth shut about it till now, which was even harder.)
Overall, personally, I found that while the new Mac OS doesn’t warrant a “wow,” it’s still definitely worth the $29 upgrade price.Mac users can read more about Snow Leopard in my colleague Jason Parker’s full review. On the other hand, for Windows users, especially Windows 7, the release of Snow Leopard is straight-on great news.

High-end server chips breaking records
How would you like a single-chip microprocessor with more than four times the performance (on some applications) of Intel’s best Core i7?
Then consider that up to 32 of these chips can be directly connected to form a single server, achieving four times the built-in scalability of Intel’s next-generation Nehalem-EX processor.
That’s IBM’s widely anticipated Power7, which it described at last week’s Hot Chips conference. But if you’re interested, you’d better be prepared to spend a lot more than four times as much per chip. IBM isn’t talking about pricing, but large Power servers can cost more than $10,000 per processor.
IBM’s forthcoming Power7 server processor has eight cores, manages 32 threads, and includes 32MB of on-chip embedded DRAM cache. Power7 also has the highest levels of off-chip bandwidth ever achieved by a microprocessor.
Apple’s new OS geared for multicore future
Apple began shipping Snow Leopard on Friday, but the true importance of the Mac OS X update likely will emerge well afterward.
That’s because Mac OS X 10.6 begins a longer-term Apple attempt to get ahead by cracking a problem facing the entire computer industry: squeezing useful work out of modern processors. Instead of stuffing Snow Leopard with immediately obvious new features, Apple is trying to adjust to the new reality in which processors can do many jobs simultaneously rather than one job fast.
“We’re trying to set a foundation for the future,” said Wiley Hodges, director of Mac OS X marketing.
Apple shed some light on its project, called Grand Central Dispatch at its Worldwide Developer Conference in June, but most real detail was shared only in with programmers sworn to secrecy. Now the company has begun talking more publicly about it and other deeper projects to take advantage of graphics chips and Intel’s 64-bit processors.
The moves align Apple better with changes in computing. For years, chipmakers such as Intel and Advanced Micro Devices had steadily increased the clock rate of their processors, and programmers got accustomed to a performance boost with each new generation. But earlier this decade, problems derailed the gigahertz train.
First, chips often ended up merely twiddling their thumbs more because slower memory couldn’t keep the chip fed with data. Worse, the chips required extraordinary amounts of power and produced corresponding amounts of hard-to-handle waste heat.

64-bit Snow Leopard defaults to 32-bit kernel
Apple’s Snow Leopard operating system, released Friday, by default loads with a 32-bit kernel, despite running 64-bit applications.
While Mac OS X version 10.6 ships with a number of 64-bit native applications, the kernel itself defaults to 32-bit, unless the user holds down the “6” and “4” keys during boot time, at which point the 64-bit kernel is loaded. Only Apple’s X-Serve products, using Snow Leopard Server, boot into a 64-bit kernel by default.
“For the most part, everything that they experience on the Mac, from the 64-bit point of view, the applications, the operating system, is all going to be 64-bit,” Stuart Harris, software product marketing manager at Apple Australia said.
Harris said that at this stage there were very few things, such as device drivers, that required 64-bit mode at the kernel level but the option is available.
“But we’re trying to make it as smooth as possible, so people don’t end up finding that ‘oh, that doesn’t work’ because it’s not available yet,” he said.
