NASA To Cryogenically Freeze Satellite Mirrors 47

Posted by Soulskill from the ain't-it-cool dept.
coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

Submission + - Where are the Cheap Thin Clients? 1

Submitted by Darren Ginter
Darren Ginter writes: I am compelled by many aspects of desktop virtualization with one exception: the cost of the thin clients, which typically exceed that of a traditional box. I understand all of the benefits of desktop virtualization (and the downsides, thanks) but I'm very hung up on spending more for less. While there are some sub-$200 products out there, they all seem to cut corners (give me non-vaporware that will drive a 22" LCD at full resolution). I can PXE boot a home brew Atom-based thin client for $130 but I'd prefer to be able to buy something assembled. Am I missing something here?

Scientists Say a Dirty Child Is a Healthy Child 331

Posted by samzenpus from the snack-is-going-to-be-on-the-floor-today dept.
Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

Do its pipes get filled with enormous amounts of materiel?

I believe that the Rolling Stones answered this decades ago:

Hey! You! Get off of my cloud
Hey! You! Get off of my cloud
Don't hang around 'cause tubes'll crowd

Submission + - Incompatibility not a Problem for Apple

Submitted by Darren Ginter
Darren Ginter writes: Apple just announced that they sold more than 3 million Macs last quarter. Without feeding the zealots, this has me wondering if Windows compatibility is really that important anymore. While I do realize that a portion of the Macs do wind up with some flavor of Windows, most of them seem to do just fine without. My question — was compatibility ever that important or have we changed the ways in which we get things done? Or is Photoshop the only thing needed by aspiring operating systems?

Windows Server Trusts Samba4 Active Directory 182

Posted by timothy from the honey-it's-not-that-you-don't-trust-me dept.
Darren Ginter writes "A group of Samba v4 developers recently spent a week in Redmond to work with Microsoft on Active Directory interoperability(?!). The result? Windows Server will now join, trust and replicate a Samba-based Active Directory using Microsoft-native protocols. Although Samba v4 is still in the alpha stages, this is a huge step for open source. Or it could be a trap."

that design doesn't look much better than the current one

Sure it does - it gives you scale. I, for one, never spent the time required to appreciate the differences in scale. So this new graphical representation provided me with an immediate and intuitive grasp on the situation. Sure - the numbers are there. But I never really thought about them beyond being a number (I'm sure that non-chemists can appreciate and forgive this ignorance).

And the gaps create an immediate sense of wonder. I think wonder is only a good thing (perhaps something that is missing from today's youth).
