Vigile writes "While few would argue with the performance advantages of solid state drives, the relative cost compared to spindle-based disks still make them a luxury item. The promise of hybrid storage solutions is to combine the benefits of both — large capacities with standard drive technology and performance advantages of solid state. PC Perspective published an article comparing several different solutions that vary in their approach to hybrid storage. The OCZ RevoDrive Hybrid combines a standard 2.5-in drive with a PCI Express-based SSD that offers the best overall performance and largest cache size. Seagate's new Momentus XT 2.5-in solution embeds the cache on the PCB of the drive, allowing notebook users to install this solution easily. Finally, the Intel chipset-based caching option combines either a 2.5-in or mSATA SSD with a standard hard drive on either desktop or mobile platforms, allowing the most flexibility of any other hybrid solution. All three have advantages for specific consumers, though, and varying performance levels to go along with them."

jfruhlinger writes "One of the great banes of election season is that any politician can shell out a few pennies per voter and phone-spam thousands of people who'd rather not hear a recorded pitch. But turnabout's fair play, and now a service called reverse robocall will deliver your recorded message to elected officials as often as you'd like for a nominal fee. If there's a representative you'd like to call repeatedly, check them out."

ananyo writes "Nano-sized flakes of graphene oxide can be spun into graphene fibers several meters long, researchers in China have shown. The strong, flexible fibers, which can be tied in knots or woven into conductive mats, could be the key to deploying graphene in real-world devices such as flexible batteries."

An anonymous reader sends this excerpt from a report at Al Jazeera "The administration of U.S. President Barack Obama has launched a virtual embassy for Iran in what it said was a bid to promote dialogue with the Iranian people in the absence of formal diplomatic ties. The web-based embassy went online on Tuesday in English and Farsi, offering visitors what it described as 'another perspective' for Iranians who 'remain hungry for information about the United States.' 'This website is not a formal diplomatic mission, nor does it represent or describe a real U.S. embassy accredited to the Iranian government,' the U.S. state department said in an introductory note. 'But, in the absence of direct contact, it can work as a bridge between the American and Iranian people.'"

Velcroman1 writes "A security hole in Facebook allowed almost anyone to see pictures marked as private, an online forum revealed late Monday. Even pictures supposedly kept hidden from uninvited eyes by Facebook's privacy controls aren't safe, reported one user of a popular bodybuilding forum in a post entitled 'I teach you how to view private Facebook photos.' Facebook appears to have acted quickly to eliminate the end-run around privacy controls, after word of the exploit spread across the Internet. It wasn't long before one online miscreant uploaded private pictures of Facebook founder Mark Zuckerberg himself — evidence that the hack worked, he said."

New submitter Geist3 writes "Forbes has an article by Venkatesh Rao asserting that the safest investment for both corporations and individuals is in software developers. Throwing money at talented coders now — even on random projects — will build relationships that are likely to pay off big in the future. 'In what follows, I am deliberately going to talk about the developers like they are products in a meat market. For practical purposes, they are, since the vast majority of them haven't found a way to use their own scarcity to their advantage.'"

Many scientists (mainly Japanese and Russian) have dreamed of cloning a mammoth over the years. When the mammoth genome was partially reconstructed in 2008, that dream seemed a bit closer. Besides the millions of dollars needed for such a project, the biggest hurdle was the lack of a good sample of mammoth DNA. That hurdle has now been cleared, thanks to the discovery of well-preserved bone marrow in a mammoth thigh bone. Russian scientist Semyon Grigoriev, acting director of the Sakha Republic's mammoth museum, and colleagues from Japan's Kinki University say that within 5 years they'll likely have a clone. From the article: "What's been missing is woolly mammoth nuclei with undamaged genes. Scientists have been on a Holy Grail-type search for such pristine nuclei since the late 1990s. Now it sounds like the missing genes may have been found."

Harperdog points out this article "about the Bay Model in Sausalito, California, which was built in 1959 to study a (terrible) plan to dam up San Francisco Bay. The model was at the forefront of research and testing on water issues that affected all of California; its research contributions have been rendered obsolete by computer testing, but there are many who think it could contribute still. Now used for education and tourism, the model is over 1 1/2 acres and replicates a 24-hour tidal cycle in just 14 minutes. Good stuff."

Trailrunner7 notes that some dedicated hackers who've been working on jailbreaking RIM's PlayBook tablet have now "posted a detailed walkthrough of how users can accomplish the same task on their own. The technique requires the use of a custom tool, but otherwise is fairly straightforward. One of the researchers, known as Neuralic, posted the walkthrough to Pastie.org Tuesday morning. In order to begin the process, a PlayBook user need to first install the beta 2.0 version of the PlayBook software and then install the Dingleberry tool, which exploits a weakness in the PlayBook architecture which stems from the fact that the backups the device takes aren't signed."

Shipud writes "Holland was recently in the news when a psychology professor in Tilburg University was found to have committed large-scale fraud over several years. Now, another Dutch psychologist is suggesting a way to avert these sort of problems, namely by 'sharing early and sharing often,' since fraud may start with small indiscretions due to career-related pressure to publish. In Wilchert's study, he requested raw data from the authors of some 49 papers. He found that the authors' reluctance to share data was associated with 'more errors in the reporting of statistical results and with relatively weaker evidence (against the null hypothesis). The documented errors are arguably the tip of the iceberg of potential errors and biases in statistical analyses and the reporting of statistical results. It is rather disconcerting that roughly 50% of published papers in psychology contain reporting errors and that the unwillingness to share data was most pronounced when the errors concerned statistical significance.'"

First time accepted submitter bushx writes "A little over a month ago, I assumed the position of programmer and sole IT personnel at a thriving e-commerce company. All the documentation I have is of my own creation, as I've spent most of my time reverse-engineering the systems in place just so I can understand how everything works together. Since I've started, I've done everything from network and phone upgrades to database maintenance with Perl, and thus far it's been immensely rewarding. But as I dig deeper, I notice the alarming number of band-aids applied by my predecessor, and it seems like the entire company's infrastructure is just a few problems away from a total meltdown. The big question now is, how do I, as a single person, effectively audit the network, servers, databases, backups, and formulate a long-term plan that can be implemented by one person? Is it possible? Where do I begin?"

An anonymous reader writes with this news from Network World: "Dell has yanked the Dell Streak 7 tablet computer from its online stores, quietly acknowledging the failure of the Android device to catch on with consumers as the company redirects its tablet focus to combination work/play products. Word of the Streak 7's disappearance follows by a few months the death of the Streak 5, which debuted in summer 2010. The dual-core processor-powered Dell Streak 7 became available in January, marketed as a 4G wireless tablet via T-Mobile's network. Now Dell is directing would-be Streak buyers to Android and Windows Phone smartphones, and pushing a line of Windows Phone tablets for business."

TechCrunch features an article (the first of three, actually) outlining the development of a clever hardware keyboard for the iPad. It's hard to write about Kickstarter projects, because there are so many cool ideas that seem to deserve funding it's simply overwhelming. The TouchFire keyboard is one of those cool ideas, too, but it's far surpassed the founders' original funding goals and is nearing production. The TouchFire isn't wired, but it isn't wireless, either, in the conventional sense, because it provides no signal of its own: it's a transparent overlay that provides a tactile interface to the iPad's on-screen keyboard, and — the tricky part — is thin enough to actually swipe through when you're not using it for text-entry. The keyboard takes advantage of the iPad 2's built-in magnets for stability, though it works with the original iPad, too. (Hopefully an Android version will come soon, but the variety of screen resolutions and on-screen keyboard shapes makes that harder.) I talked with co-creator Steve Isaac (it's his account at TechCrunch, too) a few weeks back, and he said that the hardest part of the development work has been producing the complex mold shapes that form each collapsible key. The resulting tablet-with-keyboard reminds me superficially, and pleasantly, of the TRS-80 Model 100. (The Tandy actually had much better battery life than an iPad, but could do far less. It also weighed 3.1 pounds and cost more than a thousand dollars in 1983, which means nearly $2400 today; such is progress.) Prototypes are tight (and I don't have an iPad), but I hope to give an in-person report on the TouchFire soon.

nk497 writes "The European Commission is investigating Apple and five publishers regarding ebook pricing, after raiding ebook firms earlier this year. 'The Commission will in particular investigate whether these publishing groups and Apple have engaged in illegal agreements or practices that would have the object or the effect of restricting competition,' the watchdog said."

First time accepted submitter iZarKe writes "Version 11.60 of Opera Browser for Desktop was released today. Significant changes: the inclusion of their new HTML5 rendering engine "Ragnarök", a revamped address bar, full ECMAScript 5.1 support, support for CSS3 Radial Gradients (finally), and a very revamped Mail panel. Originally, these features were set to be released with their next major version, 12.00. However, due to more work needed for the hardware acceleration feature also to be included in Opera 12, the 11.60 intermediary release came to be, as they didn't want to hold back the other new features for that long a time."
