Razer Announces Newest Blade Gaming Laptop
Razer has announced the newest version of the Razer Blade gaming laptop, and it once again packs plenty of power into a very small space. The first feature that sticks out is a 3200x1800 touch screen display based on an Indium Gallium Zinc Oxide panel. The high resolution screen is powered by an NVIDIA GeForce 970M GPU that uses NVIDIA Optimus technology to swap with Intel Integrated Graphics for battery saving. Included RAM has been doubled to 16GB and a maximum of 512GB of storage can be installed using SSDs. The high resolution model will be available on February 16 at an MSRP of $2,199 while a 1080p version can be had for $1,999.

Kingston Announces DataTraveler 4000 Gen 2 USB Drives
Kingston has announced a pair of new USB flash drives, the DataTraveler 4000 Gen 2 and DataTraveler 4000 Gen 2 Management Ready. Both drives are FIPS 140-2 Level 3 certified to provide users with a tamper-evident seal and hardware-based 256-bit AES encryption. The combination of physical and hardware based security, along with reformatting the drive after 10 unsuccessful unlock attempts, make this drive a great choice for anyone with sensitive information. The Management Ready version offers extra features for companies including remote password reset, configuration of device policies, and compliance auditing. Both drives use USB 3.0 and are available in sizes ranging from 4GB to 64GB.

Imperfect Borders May Improve Graphene
Graphene is an atom-thick sheet of carbon atoms arranged in a hexagonal structure, similar in appearance to chicken wire. At least pristine graphene is while the real stuff tends to contain many imperfections across the sheet. Normally one would think that imperfections would negatively impact a material's properties, but researchers at Rice University have found that they may actually improve them.
One of the ways to grow graphene is with a process called chemical vapor deposition, which uses catalysts to trigger the growth of graphene, as carbon atoms fall on them. From each of these catalysts domains grow, which eventually meet up to form a single sheet. The borders of these domains tend not to align with each other, so while the hexagonal structure may exist within them, the edges may be comprised of rings containing five or seven atoms. According to the Rice researchers' new model, these grain boundaries may actually improve the sheet's mechanical properties, making them tougher, instead of introducing weak points. They may even create a band gap, a property of semiconductors that graphene lacks.
As the current work is all theoretical, it will have to be confirmed by experiments, which is harder than it may sound because the domain boundaries will have to be precisely misaligned with each other. It may not be easy, but the researchers already have an idea that may work.

Samsung Appoints New Smartphone Marketing Chief
Samsung has revealed that it has appointed Lee Sang-chul as its new smartphone marketing chief, less than a month before the company is expected to unveil is next Galaxy S device in Barcelona. Lee Sang-chul, who has worked as the head of Latin American operations and Russian operations for Samsung, is replacing Kim Seok-pil, who apparently stepped down due to health reasons. Despite the health concerns, Kim Seok-pil is expected to return to work at a later time, according to a person familiar with the matter. Lee Sang-chul will be in charge of overseeing the launch of the new Galaxy S device, which is crucial for Samsung due to the decrease in mobile earnings that the company has recently experienced.

Easing Multicore Traffic Jams with Data Structures
The saying goes that two heads are better than one, and in this case, what is true for humans is also true for processing cores, with multicore processors being more efficient than single core CPUs, to a point. That point comes when you are dealing with more than eight cores, because then the actions of the cores start running into each other. Researchers at MIT, however, have refined a data structure system to remove this problem until you reach 80 cores.
There are a variety of data structures that can be used, and each has their own advantages and disadvantages. A priority queue gives each piece of data a priority value when it is stored, and only those with the highest priority can be retrieved. With a multicore processor, each core is going to grab that data and put it in their cache, and then when one of them writes to the cache, it invalidates the caches of the other cores. To get around this, the researchers allow the cores to pull items other than the first in the queue, but then the cores have to know where to find the data.
One way to find the data is to build a link list, where each element points to the address of the next. This could lead to a similar traffic jam as before though, so the researchers instead employed a skip list, which uses multiple, smaller, linked lists. The cores are able to search these smaller lists first, to find the data, and if they do not, go down a layer to another linked list until they do find the data. This will not prevent the cores from running into each other, causing a traffic jam, but it will make it much less common.
