Submission + - Researchers create flexible, transparent, 3D non-volatile memory->

MrSeb writes: "Speaking at the American Chemical Society, James Tour of Rice University has apparently demonstrated non-volatile 3D memory chips that are transparent, flexible enough to be folded like paper, and capable of withstanding temperatures up to 1,000F (537C). According to Tour, devices based on his 3D memory could survive an accidental trip to the tumble dryer, or “even a voyage to Mars.” Perhaps most excitingly, this 3D memory is fashioned from silicon oxide, an age-old, cheap, and very-well-understood darling of the semiconductor industry that can easily be manipulated using existing CMOS processes. It seems by applying voltage to the (non-conductive dielectric) silicon oxide, conductive channels of silicon nanocrystals are created — a conductive pathway that persists until a different voltage is applied. The silicon oxide needs to be fashioned into a thin channel, but apart from that Tour’s resistive switch (it's very similar to a memristor) seems very simple. Because of the simplicity and the size of the nanocrystals (5nm), Tour seems confident that this memory can achieve very high densities. The silicon oxide memory also switches very quickly (100ns), and has a high switching threshold. The tech has been patented, and it sounds like Tour is currently talking to hardware manufacturers with the hope of building screens with transparent memory built into the display."

Submission + - Any 4G Carrier/Hotspots combinations that don't bl

An anonymous reader writes: Just got a Verizon MiFi 4510L Hotspot and was disappointed to find that standard VOIP Traffic (SIP port 5060) is blocked either in the hot spot or by Verizon. Other reports (untested) suggest that other services such as Polycom style video conferencing are blocked as well.

I know how to tunnel traffic to get around these issues, (with pain and performance hits) but would prefer to return this unit and get something else.

Are there any US carriers with 4G hotspots that provide full net access without various blocks?

Linux Kernel 2.6.32 Released 195

diegocg writes "Linus Torvalds has officially released the version 2.6.32 of the Linux kernel. New features include virtualization memory de-duplication, a rewrite of the writeback code faster and more scalable, many important Btrfs improvements and speedups, ATI R600/R700 3D and KMS support and other graphic improvements, a CFQ low latency mode, tracing improvements including a 'perf timechart' tool that tries to be a better bootchart, soft limits in the memory controller, support for the S+Core architecture, support for Intel Moorestown and its new firmware interface, run-time power management support, and many other improvements and new drivers. See the full changelog for more details."

The reason computer chips are so small is computers don't eat much.
