Bitcoin Fork Divides Community

HughPickens.com writes: The Bitcoin community is facing one of the most momentous decisions in its six-year history. The Bitcoin network is running out of spare capacity, and two increasingly divided camps disagree about what, if anything, to do about the problem. The technical issue is that a block, containing a record of recent transactions, currently has a 1MB limit. Increasing the block size would allow more transactions on the network at once, helping it to scale up to meet growing demand. But it would also make it more difficult for ordinary users to host full network “nodes” that validate new transactions on the network, potentially making the digital currency more centralized as a result. Now Rob Price writes that two high-profile developers have released a competing version of the codebase that risks splitting the digital currency in two. Gavin Andresen and Mike Hearn have released Bitcoin XT, an alternative version of the core software that supports increasing the block size when required. Bitcoin users will now be forced to decide between “Bitcoin Core” and Bitcoin XT, raising the prospect of a “fork, ” where the digital currency divides into two competing versions. According to Price, Core and XT are compatible right now. However, if XT is adopted by 75% of users by January 2016, it will upgrade to a larger block size that will be incompatible with Core — meaning that if the other 25% don’t then choose to convert, it will effectively split the currency into two. So far, 7.7% of the network has adopted XT, according to website XTnodes.com. “Ultimately, how the dispute is resolved may matter more than the specific decision that’s reached, ” says Timothy B. Lee. “If the community is ultimately able to reach a consensus, the process could become a template for resolving future disagreements. On the other hand, if disagreements fester for months — or, worse, if a controversial software change splits the Bitcoin network into two warring camps — it could do real damage to Bitcoin’s reputation.” Read more of this story at Slashdot.

Tesla starts testing its autopilot features with Model S drivers

As promised, Tesla’s latest autopilot features are out in the wild. A handful of Model S drivers are now testing the electric car’s upcoming semi-autonomous tech, including highway autosteer (which tackles lanes, passing and vehicle distance) and automatic parallel parking. Ideally, these vehicular pioneers will find the last remaining quirks in both the autopilot’s behavior and its interface — those edge cases that tend to creep up only in the real world. It’s not clear exactly when everyday Model S owners will get their turn, but it’s important to temper expectations. The technology isn’t really a peek at a future dominated by self-driving cars … at least, not yet. You’ll still need to flick the turn signal to pass cars (to indicate intent and absolve Tesla of liability), and the additions won’t help much when you’re stuck in city traffic. Think of this more as a step up from the lane and braking assists that you see on other cars . They’ll eliminate more of the monotony of driving, but there’s no point at which you can completely glaze over.

Parallels 11 brings Microsoft’s Cortana to Macs before Siri

The latest version of Parallels, the popular Windows virtualization tool for Mac OS X, almost feels like it’s trolling Apple. One of Parallels 11’s key features, alongside full Windows 10 support, is its ability to put Microsoft’s Cortana right on your OS X desktop. That’s right — you could have a Windows-powered virtual assistant on your Mac long before Siri reaches the desktop. Parallels has already made it possible to run Windows apps directly on your Mac desktop for years with its “Coherence mode, ” but this latest update marks the first time it’s brought over a Windows feature on its own. Slideshow-313636 In a brief demonstration, Parallel’s Cortana feature (which requires a Windows 10 virtual installation, naturally) worked just like it did on Windows 10 proper, with decent voice recognition and no noticeable delays. It can even take advantage of your Mac’s location data, making it practically indistinguishable from a native OS X app. Parallels 11 also packs in the usual performance improvements: It can launch and shut down Windows around 50 percent faster than the last version, and a new “travel mode” can save up to 25 percent of your battery life. But really, the main reason you’d want to upgrade is to put Cortana on your OS X desktop and freak out all your friends. Parallels 11 is available today for $80, though users of the past two versions can upgrade for $50. And if you need more out of your Windows virtual machine, there’s also Parallels 11 for Mac Pro Edition, which will take advantage of that machine’s beefy hardware. It’ll cost you $100 a year, or $50 a year if you’re upgrading from Parallels 9 or 10. Filed under: Software Comments Tags: Cortana, Macs, OSX, Parallels, Parallels11, Windows10

Privacy-focused Blackphone 2 is ready for pre-order

Blackphone 2, the second iteration of Silent Circle’s privacy-focused handset, is now available for pre-order — assuming you don’t mind reserving a device without knowing its price. The original Blackphone was sold at the flagship-level cost of $629, but remember, this one’s more sophisticated than its predecessor, with its front and rear covered in glass. It has a 5.5-inch 1080p display, and inside, it boasts an octa-core processor, 3GB of RAM and 32GB of storage. What makes it different from other phones with similar specs, though, is that it runs an Android-based platform called PrivatOS which includes a suite of secure apps, including ones for encrypted messaging and voice calls. We saw Blackphone 2 at the Mobile World Congress earlier this year, and we have a preview you can read to know a bit more before you pre-order a unit. The device is expected to arrive sometime in September — if you’d rather get the the Blackphone+ tablet, though, you’ll have to wait a bit more, since Silent Circle hasn’t revealed when that one will be available.

Windows Memory Manager To Introduce Compression

jones_supa writes: Even though the RTM version of Windows 10 is already out of the door, Microsoft will keep releasing beta builds of the operating system to Windows Insiders. The first one will be build 10525, which introduces some color personalization options, but also interesting improvements to memory management. A new concept is called a compression store, which is an in-memory collection of compressed pages. When memory pressure gets high enough, stale pages will be compressed instead of swapping them out. The compression store will live in the System process’s working set. As usual, Microsoft will be receiving comments on the new features via the Feedback app. Read more of this story at Slashdot.

Windows 10 won’t run games with SecuROM DRM, says Microsoft

While Windows 10 is largely good news for gamers , it turns out that those with a collection of older games laden with DRM copy protection software are going to have a hard time getting them up and running on the new OS. In an interview with Rocket Beans TV (as translated by Rock, Paper, Shotgun ) at this year’s Gamescom, Microsoft’s Boris Schneider-Johne explained that that Windows 10 won’t be able to run games that use SafeDisc and SecuROM technology. “Everything that ran in Windows 7 should also run in Windows 10,” said Johne, “There are just two silly exceptions: antivirus software, and stuff that’s deeply embedded into the system needs updating—but the developers are on it already—and then there are old games on CD-ROM that have DRM. This DRM stuff is also deeply embedded in your system, and that’s where Windows 10 says, ‘Sorry, we cannot allow that, because that would be a possible loophole for computer viruses.’ That’s why there are a couple of games from 2003-2008 with SecuROM, etc. that simply don’t run without a no-CD patch or some such.” This isn’t a bad thing for most people, though. While SafeDisc has hit the headlines before thanks to security issues in Windows— introducing access vulnerabilities into the OS , for example—it’s SecuROM that is the most famous, and the most hated of all DRM software. Developed by Sony DADC, SecuROM took a heavy-handed approach to DRM, limiting the number of installs and activations end-users had access to, as well as requiring users to check in online to keep the game running. SecuROM even counted certain hardware changes as a change of computer, forcing another activation. Read 2 remaining paragraphs | Comments

The software Stephen Hawking uses to talk to the world is now free

For almost 20 years, Intel has been building technology to help Stephen Hawking communicate with the world — and now the company is making the same software the world renowned physicist uses to write books, give speeches and talk available to everybody . For free. It’s called the Assistive Context-Aware Toolkit (ACAT), and it’s the very same software Intel baked Swiftkey into for Hawkings early last year. Releasing it as open source software was always the plan, giving engineers, developers and researchers a groundwork they can use to create technology that improves the lives of patients with motor neuron disease and other conditions that make using typical computer interfaces impossible. Right now ACAT uses webcam-based face recognition for user control, but Intel says developers can augment it with custom inputs. As is, it still works pretty well: I installed it on a Windows tablet for a quick test run and was able to type simple words by flexing my face muscles in the same manner as Professor Hawking — patiently waiting for the ACAT system to highlight the menu, letter or predictive text word I wanted before moving my cheek. The system can also open documents, browse the web and gives users surprisingly precise cursor control. The base software is available for free on Github , and Intel is hosting a separate site with documentation, videos on features and compatible sensors and a detailed manual to help users get started. If you’re having trouble, you can even contact the project’s lead directly (his email is published on the ACAT website) for help. All in all, the project’s public release is a great step forward to achieving Professor Hawking’s dream of making connected wheelchair and assistive computer technology to every person that needs it. Check out the project’s official Git.Hub page or Intel’s project page at the source link below.

Chrome add-on helps you watch Netflix with friends

If you’ve ever wanted to watch Netflix with someone not in the same room as you, here’s your chance. Thanks to a new Chrome extension called Showgoers , people can now share a viewing experience from afar by linking their Netflix accounts. It works fairly simple: once the users’ info is entered, you click the Showgoers button and it sends an invite to whoever you want to watch a movie or TV show with in real-time. The person on the other end then receives a URL, clicks and, in a matter of seconds, the synced programming will begin automatically — you can play, pause or start something else anytime. Keep in mind that Showgoers is a public beta, so you may encounter some hiccups along the way. Still, the developer says “it generally works great.” According to Showgoers, you must follow these steps for the extension to work smoothly: Be signed into their Netflix account before opening the invite URL. Have installed the Showgoers Chrome extension. Open the invite URL in Chrome.

NASA’s LADEE confirms the moon’s atmosphere has neon

NASA’s LADEE ran out of fuel and crashed into the lunar surface in 2014, but not before it collected the data needed to answer some decades-old questions about the moon. One of those is confirming that our natural satellite’s atmosphere contains neon — the same gas used to light up signs in Vegas. Astronomers have been speculating about its presence since the Apollo missions, and now LADEE’s Neutral Mass Spectrometer (NMS) instrument has proven that it exists. It’s even relatively abundant, though the moon’s atmosphere is too thin (it’s actually called “exosphere” due to that reason) to turn it into a glowing orb in the sky. NMS has thus proven that the lunar exosphere is composed mostly of helium, argon and neon. Their main source is solar winds, and they fluctuate over time, as well as exhibit peak times throughout the day. LADEE’s data shows, however, that some of the gases in the exosphere come from the moon itself: The decay of radioactive potassium-40 found in lunar rocks gives rise to argon, while thorium and uranium produce helium. As NASA’s Goddard’s Mehdi Benna said: The data collected by the NMS addresses the long-standing questions related to the sources and sinks of exospheric helium and argon that have remained unanswered for four decades. These discoveries highlight the limitations of current exospheric models, and the need for more sophisticated ones in the future.
