Submission + - Tiny ion engine runs on water (discovery.com)

Submitted by symbolset on Sunday July 14, 2013 @01:19PM

symbolset writes: Discovery News is covering a project by two engineers from the University of Michigan to pair cubesats with tiny ion engines for inexpensive interplanetary exploration. The tiny plasma drive called the CubeSat Ambipolar Thruster (CAT) will ionize water and use it as propellant with power provided by solar cells. In addition to scaling down the size of ion engines they hope to bring down the whole cost of development and launch to under $200,000.

Submission + - Rootbeer GPU Compiler allows almost any Java code to run on the GPU (github.com)

Submitted by Anonymous Coward on Saturday August 11, 2012 @07:20PM

An anonymous reader writes: Today the source code to the Rootbeer GPU Compiler was released open source on github. This work allows for a developer to use almost and Java code on the GPU. It is free, open source and highly tested. Rootbeer is the most full featured translator to convert Java Bytecode to CUDA. It allows arbitrary graphs of objects to be serialized to the GPU and the GPU kernel to be written in Java.

Submission + - You can't bypass the UI formerly known as Metro on Windows 8 (networkworld.com) 1

Submitted by colinneagle on Friday August 10, 2012 @04:14PM

colinneagle writes: The final build of Windows 8 has already leaked to torrent sites, which is giving the propellerheads a chance to dig through the code. One revelation will probably not sit well with enterprise customers: you can't bypass the don't-call-it-Metro UI.

Normally, you have to boot Windows 8 and when the tiled desktop UI (formerly known as Metro) came up, you had to click on one of the boxes to launch Explorer. Prior builds of Windows 8 allowed the user to create a shortcut so you bypass Metro and go straight to the Explorer desktop.

Rafael Rivera, co-author of the forthcoming Windows 8 Secrets, confirmed to Mary Jo Foley at ZDNet that Microsoft does indeed block the boot bypass routine from prior builds.

He also believes that Microsoft has blocked the ability for administrators to use Group Policy to allow users to bypass the tiled startup screen. There had been hope that Microsoft would at least relent and let corporate users have a bypass, if only for compatibility’s sake.

Submission + - Ubuntu Delays Wayland Plans, System Compositor (phoronix.com)

Submitted by Anonymous Coward on Friday August 10, 2012 @01:24PM

An anonymous reader writes: The Wayland-usage in Ubuntu 12.10 via setting it up as a system video compositor has been delayed to at least Ubuntu 13.04. Developers made progress on running Ubuntu on Wayland (there are experimental packages available), but they need more time to complete their work and ready Wayland. For those wanting to try out Wayland on Linux, there is a specialty Wayland LiveCD.

Submission + - DDR4 May Replace Mobile Memory For Less (computerworld.com)

Submitted by Lucas123 on Tuesday May 15, 2012 @11:40AM

Lucas123 writes: The upcoming shift from Double Data Rate 3 (DDR3) RAM to its successor, DDR4, will herald in a significant boost in both memory performance and capacity for data center hardware and consumer products alike. Because of greater density, 2X performance and lower cost, with the upcoming specification and products will for the first time mean DDR may be used in mobile devices instead of LPDDR. Today, mobile devices use low-power DDR (LPDDR) memory, the current iteration of which uses 1.2v of power. While the next generation of mobile memory, LPDDR3, will further reduce that power consumption (probably by 35% to 40%), it will also likely cost 40% more than DDR4 memory.
