Hugh Pickens writes "The NY Times reports that while online college classes are already common, on the whole, the record is not encouraging because there are two big problems with online teaching. First, student attrition rates — around 90 percent for some huge online courses — appear to be a problem even in small-scale online courses when compared with traditional face-to-face classes. Second, courses delivered solely online may be fine for highly skilled, highly motivated people, but they are inappropriate for struggling students who make up a significant portion of college enrollment and who need close contact with instructors to succeed. Research has shown that community college students who enroll in online courses are significantly more likely to fail or withdraw than those in traditional classes, which means that they spend hard-earned tuition dollars and get nothing in return. Worse still, low-performing students who may be just barely hanging on in traditional classes tend to fall even further behind in online courses. 'Colleges need to improve online courses before they deploy them widely,' says the Times. 'Moreover, schools with high numbers of students needing remedial education should consider requiring at least some students to demonstrate success in traditional classes before allowing them to take online courses.' Interestingly, research found that students in hybrid classes — those that blended online instruction with a face-to-face component — performed as well academically as those in traditional classes. But hybrid courses are rare, and teaching professors how to manage them is costly and time-consuming. 'The online revolution offers intriguing opportunities for broadening access to education. But, so far, the evidence shows that poorly designed courses can seriously shortchange the most vulnerable students.'"

KermMartian writes "The TI-84 Plus C Silver Edition isn't the first color-screen graphing calculator, or even TI's first color calculator, but it's a refresh of a 17-year-old line that many have mocked as antiquated and overpriced. From an advanced review model, the math features look familiar, solid, and augmented with some new goodies, while programming looks about on par with its siblings. The requisite teardown uncovers the new battery, Flash, ASIC/CPU, and LCD used in the device. Although there are some qualms about its speed and very gentle hardware upgrades beyond the screen, it looks to be an indication that TI will continue this inveterate line for years to come." Lots of screenshots and pictures of the innards too.

Bennett Haselton writes "Evgeny Morozov's forthcoming book To Save Everything, Click Here describes how an overly helpful 'kitchen of the future' might stifle the learning process and threaten culinary innovation. True, but we could certainly do better than the current state of how-to directions (in cooking and most other subjects) that you can find today on Google. I suggest that the answer lies not in intelligent kitchen technology, but in designing an algorithm that would produce the best possible how-to directions -- where the 'best' directions are judged according to the results that are achieved by genuine beginners who attempt to follow the directions without help." Read below for the rest of Bennett's review.

Two years ago Guile Scheme, the official extension language of the GNU project, released version 2.0, a major upgrade to the implementation. As part of the two year anniversary, the maintainers organized a challenge to hack a small project using Guile in 30 days as part of a birthday software potluck. The two coolest dishes appear to be OpenGL support using the FFI, and XCB bindings built using the XML specification for XCB: "guile-xcb is a language implemented in the Guile VM that parses the XML files used by the xcb project to specify the X protocol and compiles them into Guile modules containing all the methods and data needed to send requests to the X server and receive replies/events back. If new X extensions are added to the xcb library, guile-xcb can compile and add them with no additional work. " See the release announcement for details on the other dishes.

Following up on yesterday's news that Ubuntu for Tablets has been announced, Mark Shuttleworth answered questions about the purpose of the new version of Canonical's OS and what its intended strengths will be. He made special note of how Canonical wants the transition between desktop-Ubuntu and mobile-Ubuntu to be smooth. "When you transition from the tablet to the desktop, things don't move around. Your indicators, things like network status and time, they don't jump around on screen, they stay in the same place. That's what's really different certainly between our approach to convergence and for example Windows 8, where when you're in the desktop mode, which looks like Windows 7, and suddenly you get the new tile-based interface, it's a stark transition that can be jarring for users. In our case, you can almost think of those as gentle phase changes. When you go from phone to tablet you're stretching the device in very obvious ways. People who've used iOS on both phones and tablets would expect that. What's nice about Ubuntu is the phase change to the PC experience up from the tablet really just introduces window management, and it also introduces things like menus and dialog boxes. You aren't moving things around in dramatic ways." He added that they expect the user experiences to converge in Ubuntu 14.04. Shuttleworth also addressed the fragmentation problem faced by Android. He says manufacturers and carriers don't want to fall into that trap again, and that they've been receptive to the idea of leaving the core of Ubuntu alone while tweaking their individual services instead.

pigrabbitbear writes "It's the most modern lament in retail: Brick-and-mortar shopping has gone the way of the dodo as everyone buys their junk online. But for the once-booming online gambling market, salvation may require a reversal of that trend. For one online gaming giant, buying a casino in Atlantic City is the first step to bring Internet poker back to the U.S. In 2006, playing online poker for real cash was deemed illegal. While that didn't stop more serious players from playing, especially once the big hosts started funneling cash offshore, the FBI and DoJ's crackdown on April 15, 2011 did. The big trio of online poker – PokerStars, Full Tilt, and Absolute Poker – were all shut down, domains seized, and executives arrested on charges related to fraud, money laundering, and illegal gambling. While PokerStars and others continued operations in foreign, legal markets, the U.S. poker craze pretty much collapsed. That doesn't mean the lucrative market has gone away. Now, the Rational Group, which owns both PokerStars and Full Tilt, may be hinting at a workaround: the company is looking to buy a struggling casino in Atlantic City. Rational faces a rather large mess of regulatory hurdles, but if it does end up acquiring the Atlantic Club Casino Hotel, it would have a huge foothold in New Jersey's young market for internet gambling."

WebMink writes "Is it possible that the CEO of the company that's trying to file a trademark on 'Python' was unaware of Python's importance as a programming technology? That's what he claims — despite running a hosting company that's trying to break into cloud computing, where Python is used extensively. Still, he also regards the Python Software Foundation as a hostile American company and thinks that getting attention from half the world's geeks is a DDoS. From the article: '[The CEO, Tim Poultney,] confirmed that he'd not involved any technical staff in the decisions he'd made about the Python product brand, and told me he regretted that as it would probably have helped him understand the likely reaction to his trademark challenge. ... He said he now understood how offended the global developer community are and told me there was obviously only one outcome that was now possible.'"

FreeMichael61 writes "In the latest episode of Spy vs. Spy, China rejects accusations it's hacking U.S. companies to steal IP or bring down the grid. But there's no doubt the grid can be hacked, CIO Journal's Steve Rosenbush and Rachael King report. Industrial control networks are supposed to be protected from the Internet by an air gap that, it turns out, is largely theoretical. Internal security is often lax, laptops and other devices are frequently moved between corporate networks and control networks, and some SCADA systems are still directly connected to the internet. What security standards actually exist are out of date and don't cover enough, and corporations often use questionable supply chains because they are cheaper."

jrepin writes "The Tizen 2.0 source code and SDK are now available. 'This release includes an enhanced Web framework that provides state-of-the-art HTML5/W3C API support, a Web UI framework (including full-screen and multi-window support), additional Tizen device APIs, such as Bluetooth and NFC support, and access to the device's calendar, call history, and messaging subsystems are now available. Other highlights: The Web Runtime framework supports new configuration elements for specifying the required features and privileges, and provides the basic runtime environment for NPRuntime plugins; the Native framework supports full-featured application development and provides a variety of features such as background applications, IP Push, and TTS (Text-To-Speech)."

hypnosec writes "Keeping its promise from yesterday Ubuntu has announced an operating system for tablets dubbed 'Ubuntu for Tablets' that it says will work on tablets of any size. Advertised to work on both entry level tablets as well as high-end tablets with enterprise specifications, the operating system offers multitasking, safer sharing, instant launch of applications through the menu bar on the left, effortless switching between applications among other features." The tablet version of the OS will also be presented at Mobile World Congress later this month. Also featured at SlashCloud.

nk497 writes "The vast majority of PCs sold by British PC makers are running Windows 7 — not Windows 8. PC Pro spoke to several PC builders, with some reporting as many as 93% of recently sold machines were on the older OS. One company initially sold its PCs with Windows 8, but feedback from users soon changed that. Customers quickly began to specify systems with Windows 7, those with Windows 8 'took delivery and wanted to change back to Windows 7' – a process the firm described as a 'nightmare.' Another firm found success by installing a 'start menu' tool on Windows 8 machines, and others said the switch would have gone smoother if Microsoft has offered a Windows 8 tutorial or better explained the new OS."

An anonymous reader writes "Hollywood crime dramas are infamous for the scene when an accused is taken to a local police station and permitted a single phone call to contact a relative or lawyer. While the storyline is myth — there is no limit on the number of phone calls available to an accused or detainee — Michael Geist reports on a recent Canadian case establishing a new, real requirement for law enforcement. After a 19-year old struggled to find a lawyer using the telephone, the court ruled that police must provide an accused with Internet access in order to exercise their right to counsel."

After a laborious judging process, the Liberated Pixel Cup has finally announced the winners of the code contest. Out of the 48 entries, Lurking Patrol Comrades (now Source of Tales), a "MMORPG with a vast world, plenty of characters to speak to, both a melee and a magic based battle system, and a polished user interface," won the grand prize. The best HTML5 game was Big Island, written in Dart and playable directly from Github. The art prizes were given last August in case you missed it. Congratulations to everyone who participated!

An anonymous reader writes "From the article: 'Bombardier's electric transit technology will be tested next winter on buses in Montreal, followed in early 2014 on a route in the German city of Mannheim. The transportation giant's Primove technology is designed to allow buses to be charged by underground induction stations when they stop to let passengers hop on and off.' This technology while impressive may not make it to the U.S. even if proven successful due to the lack of popularity of public transportation. If they could only get my phone to charge wirelessly." The article says that the induction charging stuff could also be used to charge trains.

With the Linux 3.8 merge over, the Intel Linux graphics developers are looking toward 3.9. From a weblog entry by one of them: "Let's first look at bit at the drm core changes: The headline item this time around is the reworked kernel modeset locking. Finally the kernel doesn't stall for a few frames while probing outputs in the background! ... For general robustness of our GEM implementation we've clarified the various gpu reset state transitions. This should prevent applications from crashing while a gpu reset is going on due to the kernel leaking that transitory state to userspace. Ville Syrjälä also started to fix up our handling of pageflips across gpu hangs so that compositors no longer get stuck after a reset. Unfortunately not all of his patches made it into 3.9. Somewhat related is Mika Kuoppala's work to fix bugs across the seqnqo wrap-around. And to make sure that those bugs won't pop up again he also added some testing infrastructure. " The thing I am most looking forward to is the gen4 relocation regression finally being fixed. No more GPU hangs when under heavy I/O load (the bane of my existence for a while now). The bug report is a good read if you think hunting for a tricky bug is fun.

hypnosec writes "Canonical has a countdown on its site that indicates a possible tablet announcement tomorrow. With the Ubuntu Touch developer preview launching this week, the announcement about a tablet or at least an operating system for a tablet from Canonical has, it seems, taken a backseat. From the countdown that reads "Tick, tock, tablet time!" it is evident that Canonical is going to make some announcement about tablets tomorrow."

Michael Ross writes "Upon hearing the name "Enyo," one may wonder if the speaker is referring to the Greek war goddess, or if it is the name of some Celtic New Age music with a Latin twist. In the world of front-end software development, Enyo is a cross-platform open-source JavaScript framework that can be used to build HTML5 web applications for the desktop and for mobile devices, including those powered by iOS and Android. The project website bills it as "an object-oriented JavaScript application framework emphasizing modularity and encapsulation." Any programmer interested in learning Enyo — or at least exploring what it is capable of — can consult the online documentation and the forums, but a more time-efficient approach might be to read a book focusing on the topic, such as Enyo: Up and Running, written by Roy Sutton, a contributor to the project." Read below for the rest of Michael's review.

sfcrazy writes "Mark Shuttleworth has for the first time talked about the privacy issues in Ubuntu Dash after being criticized by EFF and FSF. He mentioned some changes in the way use can 'disable' the search results. However the company has showed that under no circumstances they will disable the online search by default as demanded by EFF and FSF. Shuttleworth was simply spinning the wheel moving things around to give an impression that something has been done where as the core problem remains — Dash sends keystrokes by default and legally every user agrees to send such keystrokes to PRODUCT.canonical.com server to be shared with partners like Facebook."

dsjodin writes "Last year, LotrProject brought us extraordinary statistics on the population of Middle-Earth. Now, they have released an interactive tool for analysis of the Silmarillion, the Hobbit and the Lord of the Rings. With keyword frequency search, character mentions, sentiment analysis and network diagrams of character interactions it is a beautiful set of data visualizations and fascinating for fans and non-fans alike. The site can for example be used to find out that bacon is mentioned seven times in the Hobbit while only two times throughout the entire the Lord of the Rings."
