Submission + - Once thought safe, DDR4 memory shown to be vulnerable to "Rowhammer" (arstechnica.com)
An anonymous reader writes: Physical weaknesses in memory chips that make computers and servers susceptible to hack attacks dubbed "Rowhammer" are more exploitable than previously thought and extend to DDR4 modules, not just DDR3, according to a recently published research paper. The paper, titled How Rowhammer Could Be Used to Exploit Weaknesses in Computer Hardware, arrived at that conclusion by testing the integrity of dual in-line memory modules, or DIMMs, using diagnostic techniques that hadn't previously been applied to finding the vulnerability. The tests showed many of the DIMMs were vulnerable to a phenomenon known as "bitflipping," in which 0s were converted to 1s and vice versa.
Submission + - Canonical Finally Lets Users Move the Unity Launcher to Bottom in Ubuntu 16.04 1
prisoninmate writes: It is official, the packages needed to move the Unity Launcher of Ubuntu Linux to the bottom of the screen have finally landed in the main repositories of the Ubuntu 16.04 LTS (Xenial Xerus) operating system, due for release on April 21, 2016. Softpedia reported that Ubuntu users might be able to move the Unity7 Launcher at the bottom edge as a rumor in February, but now they confirm it finally landed for Ubuntu 16.04 LTS. It is not known if Canonical will implement a visual setting in the Apperance -> Behaviour panel for users to easily switch between having the Unity Launcher on the left of at the bottom of the screen for the final release of Ubuntu 16.04 LTS, but you can do it by running a simple command.
Submission + - Intel Unveils Skull Canyon Gaming NUC: Core i7, Iris Pro Graphics, Thunderbolt 3 (hothardware.com)
MojoKid writes: Intel first hinted at their upcoming Skull Canyon NUC small form factor PC at CES 2016 in January, but the company is now ready to give this slightly bigger, badder NUC its official debut. Skull Canyon manages to cram high-end Intel silicon within an enclosure that measures just 8.5" x 4.6" x 0.9" and has a volume of just 0.69 liters. Inside, there is a sixth generation Intel Core i7-6770HQ processor with 45W TDP and integrated Iris Pro Graphics 580 with on-board eDRAM. On the memory front, up to 32GB of 2133MHz DDR4 is supported, while storage duties are covered by two M.2 slots that support the latest NVMe PCIe SSDs. Also on-board is Intel 802.11ac Wi-Fi, Bluetooth 4.2, and GbE and even a consumer infrared sensor if you want to use Skull Canyon as a media box. For external ports you'll find a full-size HDMI 2.0 port, Mini DisplayPort 1.2, four USB 3.0 ports, an SD slot which can accommodate up to 512GB, and support for Thunderbolt 3 (40GBps) and USB 3.1 using a USB Type-C connector. Intel says that a barebones Skull Canyon NUC (NUC6i7KYK) has an estimated street price of $650. Preorders for the NUC6i7KYK SKU will begin next month and shipments will commence in May.
Submission + - One of the Largest Hacks Yet Exposes Data on Hundreds of Thousands of Kids (vice.com)
lorenzofb writes: One of the largest hacks ever exposes the identities of hundreds of thousands of kids. A hacker broke into the site of the popular toy company VTech and was able to easily get 4.8 million credentials, and 227k kids' identities using SQL injection. The company didn't find out about the breach until Motherboard told them. According to Have I Been Pwned, this is the fourth largest consumer data breach ever.
