Intel and SGI Test Full-Immersion Cooling For Servers

itwbennett (1594911) writes “Intel and SGI have built a proof-of-concept supercomputer that’s kept cool using a fluid developed by 3M called Novec that is already used in fire suppression systems. The technology, which could replace fans and eliminate the need to use tons of municipal water to cool data centers, has the potential to slash data-center energy bills by more than 90 percent, said Michael Patterson, senior power and thermal architect at Intel. But there are several challenges, including the need to design new motherboards and servers.” Read more of this story at Slashdot.

Navy Debuts New Railgun That Launches Shells at Mach 7

Jeremiah Cornelius writes: “The U.S. Navy’s new railgun technology, developed by General Atomics, uses the Lorentz force in a type of linear, electric motor to hurl a 23-pound projectile at speeds exceeding Mach 7 — in excess of 5, 000 mph. The weapon has a range of 100 miles and doesn’t require explosive warheads. ‘The electromagnetic railgun represents an incredible new offensive capability for the U.S. Navy, ‘ says Rear Adm. Bryant Fuller, the Navy’s chief engineer. ‘This capability will allow us to effectively counter a wide range of threats at a relatively low cost, while keeping our ships and sailors safer by removing the need to carry as many high-explosive weapons.’ Sea trials begin aboard an experimental Navy catamaran, the USNS Millinocket, in 2016.” Read more of this story at Slashdot.

Samsung Claims Breakthrough In Graphene Chip Design

jfruh (300774) writes “Graphene, a carbon-based crystalline lattice that is extremely strong, lightweight, and an excellent conductor of electricity and heat, is coveted as a potential base for semiconductor chip design, and Samsung, working with the Sungkyungkwan University School of Advanced Materials Science and Engineering, has claimed a big jump towards that goal. With IBM also making progress in this realm, the days of silicon could actually be numbered.” Read more of this story at Slashdot.

Seagate Releases 6TB Hard Drive Sans Helium

Lucas123 (935744) writes “Seagate has released what it said is the industry’s fastest hard drive with up to a 6TB capacity, matching one released by WD last year. WD’s 6TB Ultrastar He6 was hermetically sealed with helium inside, something the company said was critical to reducing friction for additional platters, while also increasing power savings and reliability. Seagate, however, said it doesn’t yet need to rely on Helium to achieve the 50% increase in capacity over it’s last 4TB drive. The company used the same perpendicular magnetic recording technology that it has on previous models, but it was able to increase areal density from 831 bits per square inch to 1, 000. The new drive also comes in 2TB, 4TB and 5TB capacities and with either 12Gbps SAS or 6Gbps SATA connectivity. The six-platter, enterprise-class drive is rated to sustain about 550TB of writes per year — 10X that of a typical desk top drive.” Read more of this story at Slashdot.

Dyn.com Ends Free Dynamic DNS

First time accepted submitter mkitchin (1285710) writes in with news about Dyn ending its free DNS service. “For the last 15 years, all of us at Dyn have taken pride in offering a free version of our Dynamic DNS Pro product. What was originally a product built for a small group of users has blossomed into an exciting technology used around the world. That is why with mixed emotions we announced the end of that free hostname program today, officially turning down on May 7th.” Read more of this story at Slashdot.

Microsoft’s Security Products Will Block Adware By Default Starting On July 1

An anonymous reader writes “Microsoft [Thursday] announced a change to how it handles adware, a form of malware that pushes unwanted advertisements to the user. As of July 1, the company’s security products will immediately stop any adware they detect and notify the user, who can then restore the program if they wish. Currently, when any of Microsoft’s security products (including Microsoft Security Essentials and Microsoft Forefront) detects a program as adware, it will alert the user and offer them a recommended action. If the user doesn’t do anything, the security product will let the program continue to run until the user makes a decision.” If adware is malware, why wait until July?

CryptoPhone Sales Jump To 100,000+, Even at $3500

An anonymous reader writes “Since Edward Snowden started making NSA files public last year, GSMK has seen a jump in sales. There are more than 100, 000 CryptoPhones in use today. How secure they really are will be determined in the future. But I’m sure that some government agencies, not just in the U.S., are very interested in getting a list of users.” For the price the company’s charging for a modified Galaxy S3, it had better be as secure as they claim; otherwise, the free and open source RedPhone from Moxie Marlinspike’s Whisper Systems seems like something to think about first.

Tesla Model S Has Hidden Ethernet Port, User Runs Firefox On the 17" Screen

New submitter FikseGTS (3604833) writes “A Tesla Model S owner located a 4 pin connector on the left side of the Tesla Model S dashboard that turns out to be a disguised ethernet networking port. After crafting his owns patch cable to connect with the Tesla’s port, a networking connection was established between the Tesla Model S and a laptop computer. The Model S is running a 100 Mbps, full duplex ethernet network and 3 devices were found with assigned IP addresses in the 192.168.90.0 subnet. Some ports and services that were open on the devices were 22 (SSH), 23 (telnet), 53 (open domain), 80 (HTTP), 111 (rpcbind), 2049 (NFS), 6000 (X11). Port 80 was serving up a web page with the image or media of the current song being played. The operating system is modified version of Ubuntu using an ext3 filesystem. Using X11 it also appears that someone was able to somewhat run Firefox on both of the Model S screens. Is a jailbroken Tesla Model S on the way?” Some more details on this front would be appreciated, for anyone who has a Tesla they’d like to explore. Read more of this story at Slashdot.

NYU Group Says Its Scheme Makes Cracking Individual Passwords Impossible

An anonymous reader writes “Researchers at New York University have devised a new scheme called PolyPassHash for storing password hash data so that passwords cannot be individually cracked by an attacker. Instead of a password hash being stored directly in the database, the information is used to encode a share in a Shamir Secret Store (technical details PDF). This means that a password cannot be validated without recovering a threshold of shares, thus an attacker must crack groups of passwords together. The solution is fast, easy to implement (with C and Python implementations available), requires no changes to clients, and makes a huge difference in practice. To put the security difference into perspective, three random 6 character passwords that are stored using standard salted secure hashes can be cracked by a laptop in an hour. With a PolyPassHash store, it would take every computer on the planet longer to crack these passwords than the universe is estimated to exist. With this new technique, HoneyWords, and hardware solutions all available, does an organization have any excuse if their password database is disclosed and user passwords are cracked?.” Read more of this story at Slashdot.

60 Minutes Dubbed Engines Noise Over Tesla Model S

cartechboy (2660665) writes “Did you watch the Tesla 60 Minutes segment the other night? If you did, you might have ended up on the floor rolling around laughing like I did. Since when does the Tesla Model S electric car make audible engine noises? Or downshift? Turns out, 60 Minutes dubbed engine noises and a downshift over the Model S running footage. The show claims it was an editing error. Call it what you want, it was absolutely hilarious. A little note to TV producers assigned to cover Tesla Motors in the future: Electric cars don’t upshift or downshift.” At least they didn’t fraudulently blow it up!
