The panel also evaluated the environmental impacts of geothermal development, concluding that these are markedly lower than conventional fossil-fuel and nuclear power plants.

And that might counteract the "imaginary" fears the world leaders have that global warming causes economic hardship"

A lot of providers worked hard to increase their retention and are closing up on Giganews' 90 days.But Giganews wasn't sleeping at all, they were just working on other things — SSL access to their servers! Since other providers are joining the trend of usenet ssl access, we think it's time to clear up some questions..Continue Reading"

Submission + - Would a cheap iPhone 'developer license' work?

JJC writes: "How about if Apple issued cheap 'developer licenses' for the iPhone that allowed you to develop and run unofficial software on your own device, but didn't give you the ability to distribute your software to regular iPhones that don't have the license. That way the tinkerers of the world could have all the geeky fun they wanted, without hurting Apple's and Cingular's business interests. The licenses would be cheap enough for "hobby programmers", but expensive enough that no-one would try and sell the software they'd developed, hoping that the users would buy a developer license in order to run it. I'm thinking $100 would be the sweet price-point, and I for one would be there in a flash."

It took a little longer than we initially anticipated to get everything lined up (and even then we had a tiny snag that bumped us straight from 1.2.0 to 1.2.1 before this announcement even had time to be written). So hopefully its been worth the wait. Who am I kidding. Of course its been worth the wait. We got the RESTful flavor with new encouragement for resource-oriented architectures. Were taking mime types, HTTP status codes, and multiple representations of the same resource serious. And of course theres the international pizzazz of multibyte-safe UTF-8 wrangling. Thats just some of the headliner features. On top of that, theres an absolutely staggering amount of polish being dished out. The CHANGELOG for Action Pack alone contains some two hundred entries. Active Record has another 170-something on top of that. All possible due to the amazing work of our wonderful and glorious community. People from all over the world doing their bit, however big or small, to increase the diameter of your smile. Thats love, people. http://weblog.rubyonrails.org/2007/1/19/rails-1-2- rest-admiration-http-lovefest-and-utf-8-celebratio ns"

Submission + - Innovation and commoditization in high-performance

Submitted by Anonymous Coward on Friday January 19, 2007 @03:31AM

An anonymous reader writes: HPCwire is running an article about innovation and commoditization in high-performance computing. The premise is that the HPC community ought to embrace commodity components and either extend on them (as NVIDIA and ATI do with co-processors) or build specific integrations (as Linux Networx does with supercomputers). The argument is that innovation and communization are not necessarily contradictory, as other industries have learned. Furthermore, scientific discovery follows the mantra "standing on the shoulders of giants" anyway, meaning that an entrepreneur would be better off building on an existing market base. The article includes examples of how Opteron succeeded over Itanium and why offload-enabled Ethernet has a better chance of success than Dolphin Interconnect's "scalable coherent interface."
