Radeon R9 390 4GB Models Coming Soon
Several AMD partners are planning to release 4GB models of the Radeon R9 390 video card, with the original models featuring 8GB of VRAM. The cards are built around the 28nm "Grenada" core with 2560 stream units, 160 texture mapping units, and 64 raster operation units. The core runs at 1000MHz while the memory operates at 1500MHz, and the price point of the card puts it in competition with the NVIDIA GeForce GTX 900 series. The new 4GB model "is more in line to the memory requirements in current generation titles," with most games not requiring anywhere near 8GB to perform optimally. The reduction in VRAM is expected to drop the price of the card from about $329 to $299 or lower. Radeon R9 390 cards with 4GB are already planned from Sapphire, PowerColor, and XFX with the potential for more cards on the horizon.

BIOS Update Enables Intel Skylake Overclocking
With the release of Sandy Bridge processors in 2011, Intel started to sell separate models of its processors with a "K" designation, signifying that the CPU was unlocked and overclockable. It was rumored that base clock speed overclocking would return with the release of the latest Skylake processors, but the K series was again required to have access to overclocking. Fortunately for enthusiasts, ASRock has come to the rescue with a BIOS update, enabling overclocking on non-K series CPUs. The update will be released for Z170 motherboards soon and will enable base clock changes, though the multiplier will remain locked. It remains to be seen if other manufacturers will follow suit, or if users will have to choose ASRock motherboards for their non-K series Skylake overclocking needs.

Statistically Guaranteed Untraceable Text Messaging System Developed
For a number of reasons, there are millions of people around the planet using systems like Tor to hide their online activities and communications. While Tor is relatively popular, it does have some flaws that could allow an adversary to compromise it, especially if the adversary is particularly powerful. A team of researchers at MIT decided to design a system that could thwart such powerful attackers and have appropriately named it Vuvuzela, after the noisemakers from the 2010 World Cup.
Vuvuzela is a dead-drop system, so when someone sends a message, it is sent to a specific memory address in a server that the receiver checks later. To protect against someone monitoring traffic patterns to identify users, messages are sent by every user at regular intervals, even if the messages contain no information. Also the messages are wrapped in layers of encryption, which are peeled away by the servers when they arrive, but the order the messages arrive at the servers is a random permutation. Additionally the servers generate multiple dummy messages that are also encrypted and meant for other locations. If three servers are being used by Vuvuzela, an attacker could compromise two of them and still the messages would be safe because there would be too much noise to know what messages are real, where they came from, or where they are going.
As it is now, Vuvuzela is not ready to be deployed, and it has some limitations that may prevent it from being rolled out. However, it could inspire new systems with its intriguing use of differential privacy to ensure secure communication.

Hardware Roundup: Monday, December 14, 2015, Edition
A new week is here, with a few items to help kick things off. There is a look at the Phanteks Enthoo Evolv case, the full ATX version this time, which can fit a motherboard from E-ATX all the way down to Mini ITX. We have a look at the best mice from this past year, so if you need a new gaming, wireless, or simply a budget mouse, this article has you covered. The holidays are nearly here, and so is the new Star Wars movie, so why not combine the two with the Sphero Star Wars BB-8 Super Cute Droid that can be controlled via an app on your smartphone or tablet.

AMD Launches the FX-6330 Black Edition Processor
AMD Launches the FX-6330 Black Edition Processor
AMD has officially launched the FX-6330 Black Edition processor, a product that is supposed to replace the company’s FX-6300 processor that launched back in 2012. The FX-6330 is incredibly similar to the FX-6300 that it replaces, with the amount of cores and threads, L2 cache, L3 cache, memory support, and TDP all being the same. The main advantage that the new AMD FX-6330 provides is a 100MHz increase in both base and boost clock speeds, bringing its numbers up to 3.6GHz and 4.2GHz, respectively. The FX-6330 Black Edition processor by AMD, which is built on the 32nm SOI HKMG process, also comes with the latest S3.0 cooler, which provides more surface area, higher air volume circulation, and steady noise output when compared to previous generation coolers.
The AMD FX-6330 retails for $109.99, which is roughly the same MSRP that the FX-6300 featured, but is unfortunately only available in the Asian Pacific market. Additional details about the new AMD processor can be found within the source link below.

Machine Learning Made to Mimic Humans
While real artificial intelligence has not reached the heights predicted by science fiction yet, the fact is that it has existed for decades. Continually researchers have been working to improve upon machine learning methods, with the ultimate goal of matching the capabilities of the human mind. Now researchers at New York University have successfully taught a computer to recognize and draw symbols similarly to the way humans do.
From a young age, humans are able to learn simple visual concepts, like characters to a language, with just a few examples, but it can take thousands of examples before a computer gets it right. To cut down on that number, the researchers developed a Bayesian Program Learning (BPL) framework. It works by having the program recreate the symbol using computer code, and does so in a probabilistic way, so each time the code is run it produces a slightly different version of the symbol. This generative approach allows it to learn the symbol more quickly, and how a symbol can vary just because of who draws it.
To test the effectiveness of this approach, the researchers set up a visual Turing test with various characters. Less than a quarter of the judges did better than chance in the test, proving this approach's power.
