Foremay claims to have the first 2TB, 2.5-inch SSDs

It’s been relatively easy for awhile to get a solid-state drive with 2TB or more of storage — if you’ve been willing to buy a large PCI Express card , that is. Foremay is bringing that kind of capacity to a more portable form. It claims that both its TC166 (for end users) and SC199 (industrial) drives are the first to stuff 2TB of flash memory into a 2.5-inch SATA enclosure. The 9.5mm thickness should let them fit into many laptop hard drive bays and space-sensitive machinery without having to give up all those valuable extra bytes. Before reaching for a credit card, however, we’d warn that there aren’t many details so far — we don’t know the performance, or how much it costs to buy either model. We’ve reached out and will get back if there’s firmer details, but at least corporate customers who want speed and ample storage in one drive will be glad to hear that Foremay’s new SSDs are already in mass production.

3D Printable Ammo Clip Skirts New Proposed Gun Laws

Sparrowvsrevolution writes “Over the past weekend, Defense Distributed successfully 3D-printed and tested a magazine for an AR semi-automatic rifle, loading and firing 86 rounds from the 30-round clip. That homemade chunk of curved plastic holds special significance: Between 1994 and 2004, so-called ‘high capacity magazines’ capable of holding more than 10 bullets were banned from sale. And a new gun control bill proposed by California Senator Dianne Feinstein in the wake of recent shootings would ban those larger ammo clips again. President Obama has also voiced support for the magazine restrictions. Defense Distributed says it hopes to preempt any high capacity magazine ban by showing how impossible it has become to prevent the creation of a simple spring-loaded box in the age of cheap 3D printing. It’s posted the 3D-printable magazine blueprints on its website, Defcad.org, and gun enthusiasts have already downloaded files related to the ammo holders more than 2,200 times.” Read more of this story at Slashdot.

Quantum dots help return ‘Triluminos’ RGB LED lighting to Sony HDTVs

While 4K TVs are excellent, for the next couple of years most of us will still be selecting a 1080p model when we’re out shopping, and now we’ve got a little more detail about some of the new ones Sony announced last week . After letting its ” Triluminos ” RGB LED lighting technology fall by the wayside after 2009 because of its high cost, Sony has brought the brand back in this year’s HDTVs. Noted in the press release and highlighted today in the MIT Technology Review , this iteration uses QD Vision’s quantum dot technology to enhance the red/green/blue LED backlighting the series is known for. According to the CTO of QD Vision, the TVs start with a blue backlight — instead of the standard white LED — which stimulates quantum dots that emit “pure green and pure red.” Sony was very proud of its Triluminos tech at the show and our experience at demonstrations seemed to validate the quality of the approach. While we’ve been hearing about quantum dots for years , this is reportedly their first appearance in a mass produced consumer product, once it hits homes we’ll be able to tell if the wait was truly worth it.

Remote Linksys 0-Day Root Exploit Uncovered

Orome1 writes “DefenseCode researchers have uncovered a remote root access vulnerability in the default installation of Linksys routers. They contacted Cisco and shared a detailed vulnerability description along with the PoC exploit for the vulnerability. Cisco claimed that the vulnerability was already fixed in the latest firmware release, which turned out to be incorrect. The latest Linksys firmware (4.30.14) and all previous versions are still vulnerable.” Read more of this story at Slashdot.
