Open WebOS Releases Core Apps; Reveals Touchpad Won't Be Supported
Caught via the H is news that more components of webOS have been released: "The core applications provide a comprehensive set of platform user applications, including Email, Calendar, Contacts, Memos, Accounts, Clock and Calculator." Additionally, HP has opened up the development branch of system manager: "We are excited to open up the active development branch of our upleveled System Manager. This major upgrade incorporates the latest QtWebKit and Qt technologies in an improved architecture. Modern QtWebKit now underlies all applications, providing state-of-the-art support for HTML rendering and I/O. The latest stable release of Qt has been integrated across the system, eliminating alternate rendering paths and providing a clean base for the future. These changes bring enhanced stability and performance to Open webOS." As always, source can be had from the Open webOS github. A bit of bad news for existing device owners, however: "...we are aiming for support on future hardware platforms ...

Cause of LED Efficiency Droop Finally Revealed
An anonymous reader writes "Researchers from the University of California, Santa Barbara, in collaboration with colleagues at the École Polytechnique in France, have been able to prove the theory behind LED 'droop.' LED droop is the term for how LEDs emit less light when the amount of current being pushed through them goes above a certain level. 'The cost per lumen of LEDs has held the technology back as a viable replacement for incandescent bulbs for all-purpose commercial and residential lighting.' Now that we understand what causes this, we should start to see research go into technology to circumvent LED Droop. 'LEDs have enormous potential for providing long-lived high quality efficient sources of lighting for residential and commercial applications. The U.S. Department of Energy recently estimated that the widespread replacement of incandescent and fluorescent lights by LEDs in the U.S. could save electricity equal to the total output of fifty 1 GW power plants.'" A pre-print of the ...

Airbnb Open Sources Rendr, A Library For Running Backbone.js Apps On Both Client And Server
Airbnb today announced that it is open sourcing Rendr, its library for running Backbone.js apps seamlessly on both the client and the server. After launching its Chronos cron replacement a few weeks ago, this marks the company’s second major contribution to the open source ecosystem this year. Airbnb originally developed Rendr for its mobile site. A few months ago, Airbnb talked about how it started using Node.js to bring its listing to users. To provide a good, fluid user experience, Airbnb’s Spike Brehm said at the time, more and more of the application logic for many apps has now moved to the client. The company itself previously took this approach by using Backbone.js and Rails. This, however, means the application logic is then “somewhat arbitrarily split between client and server, or in some cases needs to be duplicated on both sides.” It also, the Airbnb team argues, post challenges when it comes to SEO, performance and maintainability because the app is then divided into ...

OpenWLANMap: Free WLAN-Based GPS Replacement
flok writes "There are a couple of commercial products which can tell you where you are by the MAC addresses of access points in your neighbourhood. E.g. the iphone uses a system like this. There's now an open offering for this: OpenWLANMap. With this website, you can enter your access point mac address with your GPS location and then others can use that to navigate. There is also an app for your mobile which automatically enters this data, and you can upload data from e.g. Airomap and other wardriving applications."

Digg Hints Its Replacement For Google Reader Will Include Social Media Content
RougeFemme writes "To capitalize on Google Reader's shutdown, Digg is building an RSS reader from scratch. But this Reader replacement will go beyond RSS to include social media content, like Facebook, Tumblr, Hacker News, Reddit, LinkedIn, etc. From their blog post: 'Google did a lot of things right with its Reader, but based on what we’re hearing from users, there is room for meaningful improvement. We want to build a product that’s clean and flexible, that bends easily and intuitively to the needs of different users. We want to experiment with and add value to the sources of information that are increasingly important, but difficult to surface and organize in most reader applications — like Twitter, Facebook, Tumblr, Reddit, LinkedIn, or Hacker News. We likely won’t get everything we want into v1, but we believe it’s worth exploring."
