Review: Microsoft Office 365 Home Premium Edition hopes to be at your service

Office 365 Home Premium Edition’s lineup of software, ready to stream to your PC today. Today, Microsoft releases Office 2013—the first full release of Microsoft’s latest-generation productivity suite for consumers. Office 2013 has already made a partial debut on Microsoft’s Windows RT tablets, though RT users will get a (slight) refresh with the full availability of the suite. The company gave consumers an open preview of Office last summer, which we reviewed in depth at the time of the suite’s announcement. So there aren’t any real surprises in the final versions of the applications being releasing today, at least as far as how they look and work. Today’s release, however, marks the first general availability of Microsoft’s new subscription model under the Office 365 brand the company has used for its hosted mail and collaboration services for businesses. While the applications in Office are being offered in a number of ways, Microsoft is trying hard to steer consumer customers to Office 365 Home Premium Edition, a service-based version of the suite that will sell for $100 a year. And just as Windows 8’s app store started to fill up as the operating system approached release, the same is true of Office’s own app store—an in-app accessible collection of Web-powered functionality add-ons for many of the core Office applications based on the same core technologies (JavaScript and HTML5) that power many of Windows 8’s interface-formerly-known-as-Metro apps. Now, the trick is getting consumers to buy into the idea of Office as a subscription service and embracing Microsoft’s Office “lifestyle,” instead of something they buy once and hold onto until their computers end up in the e-waste pile.

Starved brains kill memory-making to survive

“Thanks for the memories, but I’d prefer a bite to eat.” UFL.edu As the organ responsible for maintaining equilibrium in the body and the most energy-demanding of all the organs, the brain takes a lot of the body’s energy allocation. So when food is in short supply, the brain is the organ that is fed first. But what happens when there isn’t enough food to fulfill the high-energy needs of the brain and survival is threatened? The brain does not simply self-allocate available resources on the fly; instead it “trims the fat” by turning off entire processes that are too costly. Researchers from CNRS in Paris created a true case of do-or-die, starving flies to the point where they must choose between switching off costly memory formation or dying. When flies are starved, their brains will block the formation of aversive long-term memories, which depend on costly protein synthesis and require repetitive learning. But that doesn’t mean all long-term memories are shut down. Appetitive long-term memories, which can be formed after a single training, are enhanced during a food shortage.

Yes, that PC cleanup app you saw on TV at 3 a.m. is a waste

Step one: incite panic. MyCleanPC.com Maybe you’ve seen the ads on the Internet or on TV in the wee hours of the morning. They make lofty promises: get rid of blue screens and error messages! Increase your speed! Clean up your system! But even when these PC cleanup apps aren’t just malware in disguise, the things they’re doing for your PC are often dubious. Many either replicate tasks that can be handled by built-in utilities or do things that could cause more problems than they solve. To highlight just why you and your loved ones should never let these applications anywhere near your PC, we picked one that we’d recently seen ads for: MyCleanPC. It’s the archetypal Windows cleanup app—and you probably shouldn’t install it. Intimidation tactics The standard ad for a PC cleanup app follows the same basic format as this ad from MyCleanPC.com . These ads for PC cleanup products often follow the same basic formula: appeal to people with slow or buggy PCs, throw in a few shots of an operating system that looks kind of like Windows, tack on some “customer testimonials,” and offer a free diagnosis that will make all the problems go away.

Secret backdoors found in firewall, VPN gear from Barracuda Networks

A variety of firewall, VPN, and spam filtering gear sold by Barracuda Networks contains undocumented backdoor accounts that allow people to remotely log in and access sensitive information, researchers with an Austrian security firm have warned. The SSH, or secure shell, backdoor is hardcoded into “multiple Barracuda Networks products” and can be used to gain shell access to vulnerable appliances, according to an advisory published Thursday by SEC Consult Vulnerability Lab. “This functionality is entirely undocumented and can only be disabled via a hidden ‘expert options’ dialog,” the advisory states. The boxes are configured to listen for SSH connections to the backdoor accounts and will accept the username “product” with no Update: a “very weak” password to log in and gain access to the device’s MySQL database. While the backdoors can be accessed by only a small range of IP addresses, many of them belong to entities other than Barracuda. Read 4 remaining paragraphs | Comments

MP3 files written as DNA with storage density of 2.2 petabytes per gram

The general approach to storing a binary file as DNA, described in detail below. Goldman et al., Nature It’s easy to get excited about the idea of encoding information in single molecules, which seems to be the ultimate end of the miniaturization that has been driving the electronics industry. But it’s also easy to forget that we’ve been beaten there—by a few billion years. The chemical information present in biomolecules was critical to the origin of life and probably dates back to whatever interesting chemical reactions preceded it. It’s only within the past few decades, however, that humans have learned to speak DNA. Even then, it took a while to develop the technology needed to synthesize and determine the sequence of large populations of molecules. But we’re there now, and people have started experimenting with putting binary data in biological form. Now, a new study has confirmed the flexibility of the approach by encoding everything from an MP3 to the decoding algorithm into fragments of DNA. The cost analysis done by the authors suggest that the technology may soon be suitable for decade-scale storage, provided current trends continue. Trinary encoding Computer data is in binary, while each location in a DNA molecule can hold any one of four bases (A, T, C, and G). Rather than using all that extra information capacity, however, the authors used it to avoid a technical problem. Stretches of a single type of base (say, TTTTT) are often not sequenced properly by current techniques—in fact, this was the biggest source of errors in the previous DNA data storage effort. So for this new encoding, they used one of the bases to break up long runs of any of the other three. Read 9 remaining paragraphs | Comments

All backscatter “pornoscanners” to be removed from US airports

Bloomberg is reporting that the TSA will be removing all of the remaining backscatter X-ray machines from US airports. The removal isn’t because of health concerns—instead, the machines’ manufacturer, Rapiscan Systems , failed to meet a US Congress-imposed deadline for altering the machines’ software to produce “generic passenger images,” according to the report. TSA assistant administer for acquisitions Karen Shelton Waters, speaking on behalf of the agency, noted that Rapiscan Systems would absorb the cost for the scanners’ removal, and that the removal is unrelated to Rapiscan’s alleged falsification of the machines’ abilities to protect passengers’ privacy. Nor does the removal appear to be related to ongoing questions about the safety of the backscatter X-ray technology. The CEO of OSI systems, Rapiscan’s parent company, says that rather than pitching the expensive machines into the garbage bin, the TSA will be relocating them to other government agencies. In total, there are 174 Rapiscan backscatter X-ray machines that will be pulled from airports and relocated, on top of the 76 that were  removed last year. Read 1 remaining paragraphs | Comments

Is Dell looking to kill PCs with “Project Ophelia”?

Dell’s Project Ophelia: an Android-based thin client that you can put in your pocket for around $50, eventually. Dell Dell is reportedly investigating a move to take the company private in a leveraged buy-out to clear the decks for a radical repositioning of the company. And according to a report from Atlantic Media’s Quartz , that includes relaunching Dell’s desktop and mobile business around a brand-new product: a computing device the size of a thumb-drive that will sell for about $50. Dell announced its pocket client PC, called ” project Ophelia ,” on January 8, and demonstrated it at CES. Developed by Dell’s Wyse unit, Ophelia uses a Mobile High-Definition Link (MHL) to draw power to boot from an HDTV display, or it can be powered off a USB port. It has integrated Bluetooth and Wi-Fi capability for connecting to a keyboard, a mouse, and the network, and it runs the Android 4.1 (Jelly Bean) operating system with all of the functionality of a tablet. It can also be used to power virtual instances of other desktop operating systems on a remote server or in the cloud. In other words, it’s a fusion of Wyse’s thin client technology modeled after the capabilities of a Google Chromebook—except it can be carried in a pocket. The main drawbacks are that few HDTVs currently support MHL—though such support can be found in a number of Dell flat-panel displays. Read 2 remaining paragraphs | Comments

Fastest Wi-Fi ever is almost ready for real-world use

Wilocity’s wireless chips allow 4.6Gbps transmission over the 60GHz band. Wilocity In a quiet suite removed from the insanity of the Consumer Electronics Show expo floor, a company aiming to build the fastest Wi-Fi chips in the world demonstrated its vision of wireless technology’s future. On one desk, a laptop powered a two-monitor setup without any wires. At another, a tablet playing an accelerometer-based racing game mirrors its screen in high definition to another monitor. Across the room, a computer quickly transfers a 3GB file from a wireless router with built-in storage. The suite was set up in the Las Vegas Hotel by Wilocity , a chip company specializing in wireless products using 60GHz transmissions, which are far faster than traditional Wi-Fi. Avoiding the show floor is a good idea if you’re worried about Internet connectivity, because thousands of vendors are clogging the pipes. But that’s not why Wilocity was here—they’d be able to perform the demo even in the busiest parts of CES without interference because they’re not relying on the congested bands used by regular Wi-Fi.

Amazon AutoRip: How the labels held back progress for 14 years

Michael Robertson Gabe Lawrence When Michael Robertson heard news of AutoRip , the new Amazon service that automatically adds high-quality MP3s to Cloud Player when you buy a CD, he must have had a sense of deja vu. After all, the entrepreneur introduced a similar service way back in 1999. Unfortunately, it wasn’t licensed by the recording industry, and they sued it out of existence. He tried again with a licensed service in 2007, but only one label would cut a deal and the company failed to gain traction. In a Friday interview with Ars Technica, Robertson told us that the major labels’ decision to license AutoRip represents a sea change in their attitudes toward cloud music services. Until the last couple of years, the labels were relentlessly hostile to the idea that consumers should have the freedom to store DRM-free music online. But a series of business failures and legal defeats forced the labels to face reality. And so fourteen years after Robertson first floated the concept, consumers finally have the freedom to instantly get an MP3 when they buy a CD online. Robertson’s first company, MP3.com was one of the hottest startups in Silicon Valley when it launched what we would now call a cloud music service, My.MP3.com, in 1999. The service included a feature called “Beam-It” that allowed users to instantly stock their online lockers with music from their personal CD collections. Read 11 remaining paragraphs | Comments

Samsung’s new eight-core Exynos 5 Octa SoC promises not to hog battery

Not to be outdone by Nvidia’s Tegra 4 announcement and Qualcomm’s Snapdragon 800-series announcement, Samsung took to the stage today to announce the next processor in its Exynos 5 lineup: the Exynos 5 Octa is an eight-core SoC destined for tablets and high-end smartphones. Not all of these CPU cores are created equal: four of them are high-performance Cortex-A15 cores, the very same found in the Exynos 5 Dual that powers the Nexus 10 and Samsung’s ARM Chromebook . The other four are Cortex-A7 CPU cores—these have the same feature set and capabilities as the A15 cores, but are optimized for power efficiency rather than performance. This makes the Exynos 5 Octa one of the first (if not  the first) products to actually use ARM’s big.LITTLE processor switching technology, something we outlined back in October of 2011 . The SoC is designed to dynamically split the workload between the high-performance and the high-efficiency CPU cores based on the task at hand—less strenuous activities like browsing an app store or checking e-mail might be done on the A7 cores, for instance, while gaming and number crunching could be handed off to the A15 cores.
