Comment Synology 410 and 4 1T HD's (1.6T NAS for ~$1K) (Score 1) 609

I used to have a 4U rackmount with 8 JBOD drives + a master drive, etc, etc, etc. that I built up over two years wasting about 3K on it. It died.

I ended up replacing it all for about $1000 shipped (1.7T Raid 5). It can support 4 2T HD's and

The NAS server is the 409+ non-rackmount from Synology (same-as/replaced-by the 410):

I spent quite some time researching the HD's to use and settled on these:

The newegg support was quite nice in helping m get drives from different batches (overkill, but nice).

It has worked fantastic. Supports timemachine and itunes naively, is a media server (integrates with my segate freeagent theater+ and PS3 seamlessly), the download manager rocks, and all our photo's are served up to the extended family (yea dyndns integration). Also integrates with UPS, external drives, and broadcasts the UPS issue to all my machines on the network. support for everything (and I mean everything.)

the admin interface this thing comes with is fantastic (linux on it with busybox and the ability to add your own packages):

little box seriously rocks.

Submission highest energy cosmic rays explained

An anonymous reader writes: Sci-fi author and astrophysicist Gregory Benford has a new theory about what accelerates some cosmic rays to nearly the speed of light. These ultra-high-energy cosmic rays have mystified scientists because they should interact with cosmic microwave background photons in space, losing energy before they get to Earth. Now, Benford and collaborator Raymond Protheroe say decaying magnetic fields around galaxies whose central black holes have shut down can boost cosmic rays to extreme speeds. That means astronomers don't have to resort to exotic theories about dark matter and defects in space-time to explain the high-energy particles. "Given what we know now, I think [decaying magnetic fields] are the least implausible explanation," Stanford's Roger Blandford enthuses.

Submission MIT researchers develop color changing gel 1

An anonymous reader writes: The researchers at MIT have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration and humidity. Apparently the structured gel can be used as a fast and inexpensive chemical sensor, says Edwin Thomas, a professor of materials Science and engineering at MIT. The gel will be most useful in a food processing plant, where the sensor will be able to indicate whether food that must remain dry has been overly exposed to humidity.
