| Engadget Primed: The crazy science of GPU compute Aug 20th 2012, 20:00 Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com.  As you're hopefully aware, this is a gadget blog. As a result, we're innately biased towards stuff that's new and preferably fandangled. More cores, more pixels, more lenses; just give it here and make us happy. The risk of this type of technological greed is that we don't make full use of what we already have, and nothing illustrates that better than the Graphics Processing Unit. Whether it sits in our desktops, laptops, tablets or phones, the GPU is cruelly limited by its history -- its long-established reputation as a dumb, muscular component that takes instructions from the main processor and translates them into pixels for us to gawp at. But what if the GPUs in our devices had some buried genius -- abilities that, if only we could tap into them, would yield hyper-realistic experiences and better all-round performance from affordable hardware? Well, the thing is, this hidden potential actually exists. We've been covering it since at least 2008 and, even though it still hasn't generated enough fuss to become truly famous, the semiconductor industry is making more noise about it now than ever before. So please, join us after the break as we endeavor to explain why the trend known as "GPU compute," aka "general purpose GPU (GPGPU)," or simply "not patronizing your graphics processor," is still exciting despite having let us down in the past. We'll try to show why it's worth learning a few related concepts and terms to help provide a glossary for future coverage; and why, on the whole, your graphics chip is less Hasselhoff and more Hoffman than you may have imagined.

According to the post, the camera maker is developing a new DSLR that would theoretically offer focusing performance on par with the OM-D, while providing native compatibility with the company's high-end Zuiko Digital ED lenses, such as the 90-250mm f/2.8. We reached out to Olympus reps in the US, who added the following: "A new camera body is currently under study to complement our line of Zuiko Digital Specific Four Thirds lenses. However, Olympus has NOT issued a press release on this new camera body." With Photokina just a month away, it's unclear whether or not this new mystery DSLR will make its debut there, but it's certainly a possibility. As for looks -- that's anyone's guess, though the company's social media arm opted to include a picture of the E-5, which serves as Olympus' current full-size flagship. You'll find the full Facebook post at the source link below.

What makes IBM, DelSolar, Solar Frontier and Tokyo Ohka Kogyo think they can just waltz in and claim a record of their own? By using more commonplace elements in the periodic table, that's how. The partnership's new photovoltaic cell based on copper, zinc and tin (CZTS for short) can convert light rays to electric power with a 11.1 percent efficiency rate -- still nothing to upset traditional silicon power, but a large 10 percent more efficient than anything else in the class. In its early form, CZTS can already be manufactured through ink printing and could be produced in quantities equivalent to about 500 gigawatts of power per year, or five times more than some of the next-closest alternatives. The group wants to improve CZTS' efficiency over the course of the next several years, ideally reaching the point where it's useful as a truly cheap, ubiquitous source of power. We're looking forward to the day when there's a little slice of solar energy in just about everything, hopefully including a few more hybrid cars and private aircraft.

Late to the party? Yes, but not as late as you might suppose. Roku has sold about 2.5 million streaming media boxes since the product launched in 2008. Approximately 1.5 million of those units moved in 2011, indicating an acceleration of demand. Coincidentally, those numbers roughly represent the cord-cutting movement: Reportedly, 2.65 million cable subscribers ditched their service between 2008 and 2011, with about 1.5 million of those defections happening in 2011. While cable cord-cutting is a trend, the movement is occurring in the context of customer inertia. About 100 million customers subscribe to cable, satellite, and other pay-TV providers (e.g. AT&T's U-Verse). The problematic value proposition of cutting the cord will probably keep massive inaction in place for the short term, but cannot, I believe, withstand long-term marketplace demands.

Well, Warner Bros. wants to make such frustrations a mere memory, as Tech of the Hub has found it's silently updated the use-by dates of a significant portion of its catalogue. By browsing the WB digital copy support page, it's evident most titles are now available until May 17th 2017, although we did find several exceptions. Some may discover that despite the extension their original codes won't work, but Gabe at Tech of the Hub was swiftly provided with fresh and functional ones when he notified WB, so we assume you'll get the same treatment. With streaming support now available for many of these digital copies through iCloud and expiration dates a thing of the far future, there's never been a better time to pack those shelves with limited editions and classic re-releases.
