    Huawei confirms that smartphone cameras still aren't DSLRs

    It's not the camera, it's the photographer, right? Actually, sometimes it's both, as Huawei just proved. It recently posted a lovely image, complete with a lens flare, implying that it was taken with its photo-centric P9 smartphone. "The #HuaweiP9's dual Leica cameras makes taking photos in low light conditions like this a pleasure," says the Google+ post caption. The only problem? It was actually taken with a Canon EOS 5D Mark III equipped with a very pricey 70-200mm F/2.8 lens worth $4,500 total, as the EXIF data clearly proves.

  • Apple patent application keeps your private display private

    It always bears repeating that just because a company applies for a patent doesn't mean the thing will ever see the light of day as a real product. But really, it's the outlandishness that makes these things so fun sometimes. The decidedly clunkily named "Obfuscating the Display of Information and Removing the Obfuscation Using a Filter" details a technology for obscuring information on an electronic device via the addition of "artifacts" or the manipulation of the display's "color, frequency or polarity." Aspects can be obscured by different methods at the same time, so that different information will be blocked for individual users all staring at the same display. Also interesting is the use of a filter to decode the information -- something like a pair of glasses coming between the user and the device, which can be detected by the device itself. Not a very Apple-like addition, but hey, you never know. Sometimes the future's so bright you gotta wear shades.

  • PopCap's addons are obfuscated, Blizzard is OK with that

    We've posted about both the Bejeweled and the Peggle addons here lots -- we're big fans of PopCap releasing free versions of their games for us to play in Azeroth. But all might not be well in addon land -- a few authors have come to us to point out that PopCap's addons actually contain obfuscated code in them. Obfuscation is a little hard to define -- it's a coding technique that makes code difficult to be read by other programmers, either for purposes of compression or to deliberately hide the code's function or purpose from anyone reading it. Obfuscation is strictly prohibited by Blizzard's addon policy, and so when addon authors dived into PopCap's code and found it obfuscated, they were concerned that PopCap is dodging Blizzard's rules.We spoke with PopCap about the issue, and they told us that yes, they run a program called luasrcdiet on their code to shrink it down and keep the memory footprint to a minimum. While working on their addons, they were in contact with Blizzard (and showed them the original, non-obfuscated code), and they tell us that Blizzard decided that since the purpose of the obfuscation rule in the policy was to allow the community to police their own addons for bad code (and since Blizzard trusted PopCap, there were no concerns there), then Blizzard was OK with PopCap releasing obfuscated addon code.So. Has PopCap broken the rules? In the strictest sense, yes -- the rules say no obfuscated code, and PopCap's addons do make things hard to read. But Blizzard, who wrote the rules to begin with, has no problem with making an exception for PopCap, and in doing so, their reasoning seems pretty sound. It doesn't seem fair to make an exception in any case, but we admit, if you're going to make an exception for anyone, you can't go wrong with PopCap. What do you think?
