Comment Re:To compute what? (Score 1) 238

The biggest national defense use for these machines is nuclear stockpile stewardship and theoretical development of new weapons capabilities. This is a pretty big deal and is why there are export controls on Intel chips to countries like Iran. This is why all of the fastest US machines only remain unclassified during the development stage and then convert to classified status.

Submission + - Katy Perry's cleavage pulled from Sesame Street (nwsource.com)

vortex2.71 writes: There is a minor war going occurring on YouTube regarding Katy Perry's cleavage on Sesame Street. The children's show says it won't air a taped segment featuring the "California Gurls" singer and Elmo. The pop star — who is known for her risque outfits — wore a gold bustier top as she sang a version of her hit "Hot N Cold." But some felt it was too revealing for the kid set, as reported by the Seattle Times and still available on youtube.

Comment IWMD (Score 0, Offtopic) 338

I don't really think that we should really worry about conventional information weapons so much. What we should focus more of our fear and resources on are the infamous IWMD (Information Weapons of Mass Destruction). The development of these by axis of evil nations should be monitored and sanctioned.

Submission + - Body fishing is a thriving business in China (nwsource.com) 1

vortex2.71 writes: From the Seattle Times — "Wei Jinpeng is a fisher of dead people. He scans the river about 18 miles from Lanzhou, China, for cadavers, drags them to shore with a small boat and then charges grieving families to recover their relatives' corpses. It is a thriving business. While some of the 80 to 100 bodies Wei gathers each year are victims of accidents and floods, he thinks most end up in the river after suicide or murder."

Linux is a terrific operating system, and provides a functionality that is unparalleled for a great deal of technologies that do not have good support from other operating systems. Yet for years, it was just too hard to use for most people. This has finally changed with recent distros like Ubuntu, but the time that it took to get "it just works" versions into peoples hands was fueled by developer's not listening to lay users who had trouble with the OS. Here's a useful experiment... I think we are finally at a point where I could give a go live version of Ubuntu to my mother and expect her to have some success in using it though this is perhaps not yet true for many other distros.

"Then, all it takes are some simple "right of way" rules and a small amount of computing power ... needed to avoid collisions"

These simple right of way rules result in lots of collisions on the road. Air collisions are usually fatal. It would be good to see this working in 2D (cars) first before we go to 3D (planes).

Comment Research in Labs for the Future Scientists (Score 1) 314

I think that while the average student should just learn the science as best they can. There are often good research opportunities for the superstars. Most university and industry labs would be happy to mentor smart high school students in research projects. There are lots of summer programs set up for high school students to do research. Simply search for them in your locality or consider contacting local universities and companies doing research. They need to be willing to do some grunt work in exchange for the experience, though. Its worth noting that many of these pay wages that are much better than the average highschooler usually gets. Its still worthwhile to the company because $10 per hour is still a lot less than the $25 an hour that most postdocs get or $50 an hour that professionals get.

"You will exert all of this effort to teach an individual who is really past their learning stage a skill that requires a huge amount of infrastructure...I definitely would go for teaching young children, who would benefit (and need it) more and also be more receptive to technology. "

Yes but there is always the chance that the person you teach to use the computer will reward you handsomely in their will. Young kids are much less likely to die before you and to acquire a lot of wealth to leave you if they die before you. Hee hee.

Submission + - Best handheld for running xterm, vnc, and nx?

vortex2.71 writes: I'm a physicist who basically has two aspects to my job: writing code, running code, and analyzing results. The second and to some extent the later task are performed off-sight on US DOE supercomputers, which I usually access via xterm, ssh, and scp sessions and sometimes with vnc and nx sessions. My wife has a sweet part time job that lets her work seven days in a row and then have 3 weeks off, and we would like to take advantage of her schedule by making some aspects of my job more mobile, so that we can travel more. I would therefore benefit greatly from being able to do some work from a handheld device to augment my use of a laptop and an accessible wifi connection. I'm therefore interested to hear from the community what the best handheld device is for running these applications. I am interested in high functionality xterm sessions with vim, cat, less, CTRL-C, ssh and scp (small text files only) capability and to a lesser extent, vnc and nx capability would be great. I'm also interested in something that works over a cellphone wireless network effectively and of course it would be good if it also connects to wifi. Finally, I know and use linux but am not a "linux hack", so would prefer not to have to install a non-native OS on the device. Thanks for your advice.

Submission + - Biofuels make greenhouse gases worse (nwsource.com) 1

vortex2.71 writes: The Seattle Times is reporting that "Almost all biofuels used today cause more greenhouse-gas emissions than conventional fuels if the full emissions costs of producing these "green" fuels are taken into account, two studies published Thursday have concluded.

The benefits of biofuels have come under increasing attack in recent months, as scientists took a closer look at the global environmental cost of their production.

These plant-based fuels were originally billed as better than fossil fuels because the carbon released when they were burned was balanced by the carbon absorbed when the plants grew. But that equation proved overly simplistic because the process of turning plants into fuels causes its own emissions — for refining and transport, for example.

These studies, published in the prestigious journal Science, for the first time take a detailed, comprehensive look at the emissions effects of the huge amount of natural land that is being converted to cropland globally to support biofuels development.

The destruction of natural ecosystems — whether rain forest in the tropics or grasslands in South America — not only releases greenhouse gases into the atmosphere when they are burned and plowed, but also deprives the planet of natural sponges to absorb carbon emissions. Cropland also absorbs far less carbon than the rain forests or even scrubland that it replaces.

Together the two studies offer sweeping conclusions: It does not matter if it is rain forest or scrubland that is cleared, the greenhouse-gas contribution is significant. More important, they discovered that, globally, the production of almost all biofuels resulted — directly or indirectly, intentionally or not — in new lands being cleared for food or fuel."
