New Class of Stars Are Totally Metal, Says Astrophysicist 119

Posted by samzenpus
from the hit-the-lights dept.
KentuckyFC writes Stars form when clouds of gas and dust collapse under their own gravity, generating enough heat and pressure to fuse the atoms inside them together. When this cloud of dust and gas is the remnants of a supernova, it can contain all kinds of heavy elements in addition to primordial hydrogen, helium and lithium. Now one astrophysicist has calculated that a recently discovered phenomenon of turbulence, called preferential concentration, can profoundly alter star formation. He points out that turbulence is essentially vortices rotating on many scales of time and space. On certain scales, the inertial forces these eddies create can push heavy particles into the calmer space between the vortices, thereby increasing their concentration. In giant clouds of interstellar gas, this concentrates heavy elements, increasing their gravitational field, attracting more mass and so on. The result is the formation of a star that is made entirely of heavy elements rather than primordial ones. Astrophysicists call the amount of heavy elements in a star its "metallicity". Including preferential concentration in the standard model of star formation leads to the prediction that 1 in 10,000 stars should be totally metal. Now the race is on to find the first of this new class of entirely metal stars.

I'm feeling this. I worked for Netscape back in the 90's. I'm considerig trimming that from my resume simply because it make me look too old-school. There is definite discrimination amongst up and coming companies. It's incredibly frustrating for me, a guy in his early 50's. I know a metric shit-ton of stuff, and especially the shortest path to get to the goal. Do I get hired, or even a reply on sending in a resume? No. My long work history stretching back to 1983 has me handcuffed.

I lived in the Sacramento region for over 10 years, Fair Oaks, Folsm, Grass Valley after a long and successful career in the peninsula of the Bay Area.

Fact: There are very few "traditional" tech companies around Sacramento.

Fact: The pones that are there, know that and they consistently offer ~50-60% of Bay Area wages. They only want to hire recent college grads, not experienced people.

Fact: I recently left and won't be heading back. Besides, there are lots more good looking women here in the Bay Area. :)

I'm 72 now, and still gainfully employed...just not by 35-year-old "managers" (or worse, "executives") who haven't got any substantive experience to evaluate competence. After a career consulting to IBM, Intel, HP, Amoco, DuPont (and lots more) at the CxO level on IT strategy, I semi-retired in 2001, to a small mountain town nestled in the Sierra Nevada mountains.

Interestingly enough, I too (and I'm the guy who Asked Slashdot this question) I located myself in the Sierra Nevada foothills. Howdy, neighbor.

But when I send out a perfectly good resume and use the more obvious resources there are still precious few bites for someone requiring to work remotely

How come nobody has commented on this part? No matter what age you are, requiring that you work remotely is going to make things difficult, no matter your age.

When you live in a rather remote part of the world (by choice and necessity) there aren't a lot of options. I get that I may not be paid as well for doing so, and am totally fine with that. But I'm simply not willing to move back to Silicon Valley just to make a living wage.

The thing is, I have relevant and current skills and if something new comes up I will learn it faster than anyone. I can lead a team of newcomers (common in SQA) like no ones business. I've worked with outsourced teams, and am quite well versed in overseas contacts. I've worked with github and 27signals through their earlier work and others along with tons of FOSS and OSS projects. My name is out there. You, as a fan of my side project ( know how hard we work and how incredibly diverse we are.

It's just frustrating. I'm not done yet breaking things.

+ - Nvidia Removed Linux Driver Feature Due to Windows

Submitted by RemyBR
RemyBR (1158435) writes "Softpedia points to a Nvidia Developer Zone forum post revealing that the company has removed a specific Linux feature as of the v310 drivers due to the Windows platform. A BaseMosaic user on Ubuntu 12.04 noticed a change in the number of displays that can be used simultaneously after upgrading from the v295 drivers to v310.
Another user, apparently working for Nvidia, gave a very troubling answer: "For feature parity between Windows and Linux we set BaseMosaic to 3 screens"."

The Sharing Economy Fights Back Against Regulators 192

Posted by samzenpus
from the you're-not-the-boss-of-me dept.
An anonymous reader writes in with a story about the advocacy group "Peers". The group says their goal is to “mainstream, protect, and grow the sharing economy.” "The growth of the 'sharing economy,' a loosely defined term generally referring to the internet-enabled peer-to-peer exchanges of goods, has brought with it a shift in the way we think about consumption. Its rise has been fast, and loud. What started with a few enterprising individuals willing to let complete strangers sleep in their homes and use their possessions has now developed into a formidable economic force that threatens to upend several different industries. Along the way, it has posed some major legal challenges. The companies that are pushing it forward have continually undermined local ordinances, consumer safeguards, and protectionist regulations alike. As a result, governments around the country are trying to reign them in. That’s where Silicon Valley’s newest advocacy group comes in."

The Leap Motion Controller is Sort of Like a Super Kinect (Video) 108

What the Leap Motion product (they only have one right now) does is allow you to control your computer with gestures. We're not talking about just jumping around, but "painting" on the screen with your fingers (or even chopsticks) with fine enough control that Autodesk and other drawing-orientd software vendors are working to make applications compatible with the Leap Motion Controller. And game developers? You bet! Lots of them -- and this is for a device that's not even supposed to start shipping until May 13. But, says CEO Michael Buckwald, they already have "hundreds of thousands of pre-orders," so it looks like they are developing a large market for developers (over 12,000 are in the Leap Motion developer program -- out of 50,000 who applied) so it's possible that Leap Motion could become a pretty big deal. (You can see the Leap Motion Controller in action at the end of the video.)
