Toshiba launches new enterprise-grade 4 TB hard drive

Toshiba said this morning that it's now shipping its new enterprise-grade 4 TB hard drive just a few days after Western
Digital revealed its new 4 TB drive.
Toshiba will build its new drive at the 3.5-inch manufacturing facility it bought from Western Digital just last year.
Western Digital had to sell the building in order to appease China's so-called 'MOFCOM' regulator during its acquisition
of Hitachi Storage back in 2010.
Western Digital's three-platter 4 TB SATA3 drive now faces tough competition from Toshiba's MG-03-SCA400 competing drive,
which has five 800 GB platters turning at 7,200 RPMs.
Toshiba also announced a new 6 GB SAS model, the MG-03-SCA-400, which also stores 4 TB of data and has a self-scrambling
Hard drives in Toshiba's MG series have a 64 MB buffer, 3 to 4 ms average seek latency, 8.5 ms average read seek time, and
9.5 ms average write time. Disks with smaller capacities are also available in that product range.
These are nearline drives built for continuous operation. The self-scrambling models offer near-instantaneous cryptographic
data erasure, Toshiba added.
The SATA SED models fully support the T-13 Sanitize command to scramble the contents of the disk and the older T 13 ATA
Secure Erase command. The SAS SED disks support the T-10 Sanitize feature and the Trusted Computing Group's enterprise protocols
to securely wipe drives.
According to Toshiba, the crypto-scramble features eliminate the need for lengthy data overwrite cycles and reduce IT department
expenses associated with secure data destruction and device sanitisation.
And as can be expected, now everybody is waiting for Seagate's 4 TB offering. Toshiba will ship samples of its MG 4 TB
series drives next week. Volume shipments are scheduled to arrive sometine in January 2013.

Oracle’s senior Java developer Jim Laskey says that 'Project Nashorn' is a lightweight, high-performance runtime app in Java
that uses the native Java Virtual Machine (JVM).
Overall, Nashorn will start from scratch, using entirely new code, with initial source coming from an unnamed Oracle internal
project manager, says Laskey.
Nashorn will also use MethodHandlers and InvokeDynamic APIs, as described in JSR-292. “The goal is to provide a lightweight,
to convert ASTs from the parser to JVM byte code, and a runtime to support the execution of said generated byte code. Execution
The project, part of the OpenJDK, will be moved to the OpenJDK repositories. OpenJDK is a free and open-source implementation
of the Java programming language. The initiative was recently re-invigorated by Oracle once it took ownership of Sun Microsystems
and which later attracted support from IBM and Apple after many years in the wilderness thanks to industry politics.
Nashorn is the latest effort to diversify the languages supported by the JVM, a push that started under Sun to help ensure
Java remained relevant in a world of growing language diversity.

this could be that the transition to the server isn’t seamless, and apps that might work on a test machine may or may not run

apps scale on the server. After initial enthusiasm, criticism of Node.JS set in - especially on its inability to scale.
An official project from the OpenJDK at least stands the chance of becoming something people agree on using, and could possibly
offer the IT industry some sort of an alternative that could attract some developers and which isn’t subject to the usual complexity
of frameworks and languages.

Microsoft has released its first major update to Visual Studio 2012, in what it claims is only the
first in a regular cadence of planned improvements to its main developer tool suite.
Microsoft launched Visual Studio 2012 in mid-September, but according to Steve Somasegar, corporate vice president of
Microsoft's developer division, programmers should expect regular updates at shorter intervals from now on.
"Most importantly, this isn't just about bug fixes, though it contains a few of those," Somasegar added. "This update
also delivers a wealth of new functionality into Visual Studio 2012."
Predictably, several of those new features are designed to aid developers who want to build Windows Store apps for Windows
