  • Batteries take the lithium for charge boost • The Register

    To do that, the researchers coated a lithium anode with a layer of hollow carbon nanospheres, to prevent the growth of the dendrites. via Batteries take the lithium for charge boost • The Register. As research is being done on incremental improvements in Lithium Ion batteries, some occasional discoveries are being made. In this instance,…

  • MIT Puts 36-Core Internet on a Chip | EE Times

    Today many different interconnection topologies are used for multicore chips. For as few as eight cores direct bus connections can be made — cores taking turns using the same bus. MIT’s 36-core processors, on the other hand, are connected by an on-chip mesh network reminiscent of Intel’s 2007 Teraflop Research Chip — code-named Polaris —…

  • AnandTech | Intel SSD DC P3700 Review: The PCIe SSD Transition Begins with NVMe

    We don’t see infrequent blips of CPU architecture releases from Intel, we get a regular, 2-year tick-tock cadence. It’s time for Intel’s NSG to be given the resources necessary to do the same. I long for the day when we don’t just see these SSD releases limited to the enterprise and corporate client segments, but…

  • Corning Announces Availability of USB 3.Optical Cables

    Currently available in lengths of 10 meters, Corning will also be releasing USB 3.Optical cables of 15 and 30 meters later this year.  These cables can be purchased online at Amazon and Accu-Tech. via Corning Announces Availability of USB 3.Optical Cables. As I’ve had to deal with using webcams stretched across very long distances in…

  • Battery vendors push ultracapacitor wrappers to give Li-ions more bite • The Register

    A pair of battery vendors are hoping that a new design which incorporates the use of an ultracapacitor material will help to improve and extend the life of lithium-ion battery packs. via Battery vendors push ultracapacitor wrappers to give Li-ions more bite • The Register. First a little background info on what is a capacitor: https://en.wikipedia.org/wiki/Ultracapacitor#History…

  • UW Researchers Create World’s Thinnest LED | EE Times

      The researchers harvested single sheets of tungsten selenide (WSe2) using adhesive tape, a technique invented for the production of graphene. They used a support and dielectric layer of boron nitride on a base of silicon dioxide on silicon, to come up with the thinnest possible LED. via UW Researchers Create World’s Thinnest LED |…

  • Virtual Reality | Oculus Rift – Consumer Reports

    Imagine being able to immerse yourself in another world, without the limitations of a TV or movie screen. Virtual reality has been a dream for years, but judging by current trends, it may not be just a dream for much longer. via Virtual Reality | Oculus Rift – Consumer Reports. I won’t claim that when…

  • Follow-Up – EETimes on SanDisk UltraDIMMs

    http://www.eetimes.com/document.asp?doc_id=1320775 “The eXFlash DIMM is an option for IBM‘s System x3850 and x3950 X6 servers providing up to 12.8 TB of flash capacity. (Although just as this story was being written, IBM announced it was selling its x86 server business to Lenovo for $2.3 billion).” Sadly it seems the party is over before it even…

  • Fusion-io shoves OS aside, lets apps drill straight into flash • The Register

    Like the native API libraries, directFS is implemented directly on ioMemory, significantly reducing latency by entirely bypassing operating system buffer caches, file system and kernel block I/O layers. Fusion-io directFS will be released as a practical working example of an application running natively on flash to help developers explore the use of Fusion-io APIs. via…

  • Nvidia: No magic compilers for HPC coprocessors • The Register

    And with clock speeds topped out and electricity use and cooling being the big limiting issue, Scott says that an exaflops machine running at a very modest 1GHz will require one billion-way parallelism, and parallelism in all subsystems to keep those threads humming. via Nvidia: No magic compilers for HPC coprocessors • The Register. Interesting…
