WD Announces 8TB, 10TB Helium Hard Drives 296

Posted by Soulskill from the ballooning-storage-capacity dept.
Lucas123 writes: Western Digital's HGST subsidiary today announced it's shipping its first 8TB and the world's first 10TB helium-filled hard drive. The 3.5-in, 10TB drive also marks HGST's first foray into the use of shingled magnetic recording technology, which Seagate began using last year. Unlike standard perpendicular magnetic recording (PMR), where data tracks rest side by side, SMR overlaps the tracks on a platter like shingles on a roof, thereby allowing a higher areal density. Seagate has said SMR technology will allow it to achieve 20TB drives by 2020. That company has yet to use helium, however. HGST said its use of hermetically-sealed helium drives reduces friction among moving drive components and keeps dust out. Both drives use a 7-platter configuration with a 7200 RPM spindle speed. The company said it plans to discontinue its production of air-only drives by 2017, replacing all data center models with helium drives.

You can run it in the cloud too. You'll have the same/similar latency problems as with "native" could storage. If your storage is distributed across different AZ's, latency will be worse. Depends on your provider too. Jeff Darcy gave a talk about this at LISA:

GlusterFS has proper, geo-replication which is becoming much better and HA in 3.5 (coming soon).

Cheers!

It's pretty awesome, and pretty cheap on $/Gb/Performance.
I'm biased because I'm the Puppet-Gluster dev.

You can run GlusterFS in "cloud" or on your own iron. Because it's not proprietary, the possibilities are endless, and it has a lot of very elegant features.

I prefer Puppet, but I don't think it's perfect. As a result, I've written some complicated hacks do to complicated things that aren't directly possible in core. I still think Puppet is the closest thing to being right.

Submission + - Senators Push to Preserve N.S.A. Phone Surveillance (nytimes.com)

Submitted by cold fjord
cold fjord writes: The New York times reports that the Chairman of the Senate Intelligence Committee, Senator Dianne Feinstein (D-CA), and Vice Chairman, Senator Saxby Chambliss (R-GA), are moving a bill forward that would “change but preserve” the controversial NSA phone log program. Senator Feinstein believes the program is legal, but wants to improve public confidence. The bill would reduce the time the logs could be kept, require public reports on how often it is used, and require FISA court review of the numbers searched. The bill would require Senate confirmation of the NSA director. It would also give the NSA a one week grace period in applying for permission from a court to continue surveillance of someone that travels from overseas to the United States. The situation created by someone traveling from overseas to the United States has been the source of the largest number of incidents in the US in which NSA's surveillance rules were not properly complied with. The rival bill offered by Senators Wyden (D-OR) and Udall (D-CO) which imposes tougher restrictions is considered less likely to pass. More at The New York Times.

Mozilla Launches Persona Identity Bridge For Gmail 114

Posted by samzenpus from the being-yourself dept.
An anonymous reader writes "Mozilla today announced the Persona Identity Bridge for Gmail users. If you have a Google account, this means you can now sign into Persona-powered websites with your existing credentials. The best part is of course Mozilla's pledge to its users. 'Persona remains committed to privacy: Gmail users can sign into sites with Persona, but Google can't track which sites they sign into,' Mozilla Pesrona engineer Dan Callahan promises."

How To Build a Simple Open Source Server Monitoring Solution With Mobile Support 58

Posted by timothy from the be-here-now-or-at-least-check-in dept.
reifman writes "Nothing sucks more than finding an 'Error establishing database connection' on your blog hours after the fact, but it's not easy to find inexpensive, simple monitoring solutions which support smartphone notifications. I wrote MonitorApp, a free, open source software applet which sends notifications to your iPhone (or Android) if anything goes wrong with your web site or services. This tutorial describes how to install and configure MonitorApp for your own purposes. The only cost is a $4.99 mobile application called Pushover — which links MonitorApp to your phone. Pushover also links with Nagios, a more complex open source option — but ironically, Nagios' website was down when I looked for it last month."

The Underhanded C Contest Is Back 88

Posted by Unknown Lamer from the to-eat-your-brains dept.
Xcott Craver writes "After several years of inactivity, the Underhanded C contest has returned. The object is to write a short, readable, innocent-looking computer program that nevertheless performs some evil function for reasons that are not obvious under code review. The prize is a $200 gift certificate to ThinkGeek." The deadline is July 4th, so get to hacking.

Laser Fusion's Brightest Hope 115

Posted by samzenpus from the coming-together dept.
First time accepted submitter szotz writes "The National Ignition Facility has one foot in national defense and another in the future of commercial energy generation. That makes understanding the basic justification for the facility, which boasts the world's most powerful laser system, more than a little tricky. This article in IEEE Spectrum looks at NIF's recent missed deadline, what scientists think it will take for the facility to live up to its middle name, and all of the controversy and uncertainty that comes from a project that aspires to jumpstart commercial fusion energy but that also does a lot of classified work. NIF's national defense work is often glossed over in the press. This article pulls in some more detail and, in some cases, some very serious criticism. Physicist Richard Garwin, one of the designers of the hydrogen bomb, doesn't mince words. When it comes to nuclear weapons, he says in the article, '[NIF] has no relevance at all to primaries. It doesn't do a good job of mimicking secondaries...it validates the codes in regions that are not relevant to nuclear weapons.'"
