Barence writes "Are faster grades of SD memory card worth the extra cash? PC Pro has conducted in-depth speed tests on different grades of SD card to find out if they're worth the premium. In camera tests, two top-end SD cards outshone the rest by far, while class 4 cards dawdled for more than a second between shots. However, with the buffer on modern DSLRs able to handle 20 full-res shots or more, it's unlikely an expensive card will make any difference to anyone other than professionals shooting bursts of fast-action shots. What about for expanding tablet or laptop memory? A regular class 4 or 6 card that's capable of recording HD video will also be fast enough to play it back on a tablet. The only advantage of a faster card for media is that syncing with your PC will be quicker. However, a faster card is recommended if you're using it to supplement the memory of an Ultrabook or MacBook Air."

New submitter capsfan100 writes "At Christmas I got an $89 Android tablet by MID. The 7" tablet has sufficient RAM, etc. The battery, however, was rather pathetic out of the box. It's already fading, so we know where this is headed — decent tablet, but it constantly needs the plug. How would you take this 'old' tablet and turn it into a rockin' stereo component? Is there a ROM build out there titled Pimp My Tablet Into An MP3 Player? The current music app can look up lyrics on-line. I'd like to keep that feature. Any ideas on a good app for syncing music videos with my *ahem* random music collection? Any fun, off-beat party apps this middle-aged suburban dad hasn't heard of? Since the Android security nightmare is so well documented, I'd rather not use services that require passwords. I also need top-notch security and monitoring software so I can see what my kids and their friends are doing with it next year when I'm not home while keeping them anonymous and safe on-line. As for my living room stereo system, how best to mount a sleek MP3 tablet? I was thinking velcro, but it would ruin the feel. Maybe a wall-mount arm like my HDTV has? We want to be able to unplug it and move around the room, so I'll need to upgrade the speakers to wireless. Any thoughts there? I'm not afraid of the command line — indeed, I insist on one — but no Gentoo-type projects, thank you. Just a good sleek and secure ROM for optimal tunage with all the top apps the kids are using today."
Press2ToContinue writes with this excerpt from ExtremeTech: "With products like Google's Glass, the Oculus Rift, and even certain features found on the Nintendo 3DS, augmented, mixed, and virtual reality are starting to make some headway in the consumer space. Canon, best known for its cameras, is looking to break into the mixed reality scene with its new head-mounted display. ... The core of the setup is the Canon HMD (head-mounted display) which works in conjunction with various sensors — optical and magnetic, as well as visual markers — to help create the mixed reality environment. The HMD employs two cameras located in front of each eye that captures video and shoots it off to an off-board, tethered computer. The computer then combines the real-world visuals with computer-generated visuals, and beams that back to two monitors placed in front of the eyes within the HMD. The unit combines with a development platform, dubbed the MR Platform, which allows companies to create mixed reality images to display on the HMD."
rtfa-troll writes "There has been a worldwide (all locations) total outage of storage in Microsoft's Azure cloud. Apparently, 'Microsoft unwittingly let an online security certificate expire Friday, triggering a worldwide outage in an online service that stores data for a wide range of business customers,' according to the San Francisco Chronicle (also Yahoo and the Register). Perhaps too much time has been spent sucking up to storage vendors and not enough looking after the customers? This comes directly after a week-long outage of one of Microsoft's SQL server components in Azure. This is not the first time that we have discussed major outages on Azure and probably won't be the last. It's certainly also not the first time we have discussed Microsoft cloud systems making users' data unavailable."
At last year's RSA security conference, we ran into the Pwnie Plug. The company has just come out with a new take on the same basic idea of pen-testing devices based on commodity hardware. Reader puddingebola writes with an excerpt from Wired: "The folks at security tools company Pwnie Express have built a tablet that can bash the heck out of corporate networks. Called the Pwn Pad, it's a full-fledged hacking toolkit built atop Google's Android operating system. Some important hacking tools have already been ported to Android, but Pwnie Express says that they've added some new ones. Most importantly, this is the first time that they've been able to get popular wireless hacking tools like Aircrack-ng and Kismet to work on an Android device." Pwnie Express will be back at RSA and so will Slashdot, so there's a good chance we'll get a close-up look at the new device, which runs about $800.
