Galaxy Adds New GeForce GTX 780 Model
Galaxy has added the GeForce GTX 780 HOF Edition to its stable of graphics cards, a card that the company claims is "the fastest air-cooled GTX 780 on earth." The Hall of Fame Edition cards feature a factory clock of 1058MHz, offering speeds up to 20% higher than a standard GTX 780. A white PCB combines with a Hybrid Vapor Chamber Heat Pipe cooler to provide a unique look and powerful cooling performance. The last standout feature of this new card is the Hyper Boost button on the panel of the card. When pressed it "engages special circuitry and internal optimizations, pushing clock speeds into overdrive and raising fan speed accordingly."

Encrypting Software with Mathematical Jigsaw Puzzles
Encryption is a very important security tool for computers and users, as it protects some of our most personal information, but it does more than secure passwords and credit card numbers. Software is occasionally encrypted to protect its code from being stolen and to hide any unpatched security flaws, but it is not often successful as it is limited, so as to not impair the software's performance. Now researchers at the University of California, Los Angeles have developed a new method that secures software without any impairment.
The new encryption utilizes multilinear jigsaw puzzles to break apart the often human-readable code of a piece of software into a mess of numbers. At least it will look like a mess of numbers to a human. A computer with the correct information will be able to identify the patterns among the numbers and thus operate the software. Without that information a modern computer would require hundreds of years to decrypt the software.
A consequence of this work was a breakthrough for functional encryption, allowing it to support any computable function. Functional encryption uses a function to decrypt information, instead of a single key, allowing it to except multiple inputs as verification that somewhere is allowed to access the information. Such a system allows the same encrypted packet to be sent to multiple people, and depending on their credentials, they will only be able to decrypt specific information.

Dell Begins Beta Testing Android-Powered Thumb-Size PC
Dell has something new up its sleeves, as it's preparing a thumb-size PC that runs on Google's Android OS. Dubbed Project Ophelia, this PC looks similar to a USB flash drive, except it connects via an HDMI port. Plug it in and pretty much any screen with an HDMI port can become a PC or a streaming media player. Applications, games, music, movies, and even personal files can be accessed from it, plus its WiFi and Bluetooth connectivity options allowing for wireless keyboards and mice to control the show. Hulu and Netflix streaming could be the biggest draw here, as can playing games or using some of the thousands of apps on the Google Play Store. Some enterprise features are also expected to be added, so IT administrators could have the ability to remotely secure and wipe a device if it gets lost or stolen. It sounds like a souped up version of Google's Chromecast, actually, which isn't a bad thing.
Dell is currently beta testing Project Ophelia (please give it a sweet name), and is planning to have the PC ready to launch sometime in the next several months. It's expected to cost around $100, and could be the perfect way to get into computing without dropping a ton of cash or taking up a lot of space. The specifications of Project Ophelia aren't currently known, but I imagine we won't have to wait too much longer to find that out.

Research to Improve Graphics, Digital Video, and Displays
Sight is one of the most valuable senses we have, as anyone who produces digital video or computer graphics will assure you. Despite those persons' best efforts though, sometimes what they create just does not look real because they do not have the tools to achieve realism. Researchers at Harvard University however have recently published three papers to help bridge gaps between reality and the media they produce.
One of these papers focuses on how computer graphics treat translucent objects. We have known for some time the math behind translucency, but understanding how it relates to what we see, so CG artists can make materials look real, would require a prohibitive amount of work. The researchers decided to take advantage of the power of modern computers to simplify the work by rendering thousands of images and comparing them, pixel by pixel, to find only those that are representative of all the images. They then showed those images to people, to learn how we interpret a material's translucency.
The two other research papers describe an adaptive display and tool to simplify a video editing technique normally limited to professionals. The adaptive display the paper describes takes advantage of a pattern etched into the display's surface, to present three-dimensional objects that change depending on the angle you view them at, like when you look through a window. The third paper discusses a new color-grading method, which could bring the editing of a frame's color palette to amateur videos. As the process currently requires frame-by-frame editing, it is largely limited to professional films with large budgets.
