"I was typing an email on my iPad, and I got distracted. Some time later, I set the iPad down on my desk, and an icon on my Mac appeared. I clicked it, and in seconds the Mail app was running with that partially entered email in front of me. That's the Handoff feature in action, part of the iOS 8 and OS X Yosemite updates that will ship this fall. It's a sign of a change in computing that Google and Microsoft are also pursuing, not just Apple. Liquid Computing Welcome to the next tech revolution: Liquid computing Liquid computing: The next wave of the mobile experience Apple Watch: The Internet of things' new frontier iOS 8 and OS X Yosemite are both in beta, so I can't really talk about the details of Handoff yet. But I can say it works just as Apple showed off at its recent WWDC conference's public keynote. Handoff is the first big step into a future where the notion of a device will go through a radical transformation. [ Mobile and PC management: The tough but unstoppable union. | Subscribe to InfoWorld's Consumerization of IT newsletter today. ] At first blush, what Apple is doing is blurring the lines between mobile and desktop devices. That's true, but it's only part of the actual transformation under way. There's no real name for this transformation yet, so I'm calling it liquid computing until someone else comes up with a better name. In a nutshell, what Handoff -- and liquid computing in general -- portends is a world where both data and activities move around as needed. The device isn't the center of the universe, as it has been since the first computer. Think back to the early PC era, when people first started getting PCs at home, not just at work. Remember the effort we all spent in making sure we copied our files to a disk for use at home? We had to bring our data with us or else use a network connection to a file share. That model has persisted to this day, which is why the biggest loss of corporate data remains the lost or stolen thumb drive or

The vicious intimidation campaign against WikiLeaks is wrong, dangerous and undermines the rule of law. Top US politicians have branded WikiLeaks a terrorist organization, suggested assassinating its staff, and urged corporations to shut it down. The future of our freedoms and the Internet is at stake. Let's urgently take a stand to ensure governments and companies act with restraint and due process, not escalate this fight. Sign the petition to stop the crackdown -- we can reach 1 million voices this week!

Here is a list of free ping services for you to use. I was looking for a site that had a list I could just go down and use for my pinging. I didn't find one I liked, so I decided to make my own. I also have some featured lenses where you will find some great information you can use on your own lenses, and links to a good blog about making money online with some squidoo tips.

Exploratory visualization based on multiple coordinated views is a rapidly growing area of information visualization. Ideally, users would be able to explore their data by switching freely between building and browsing in a flexible, integrated, interactive graphical environment that requires little or no programming skill to use. However, the possibilities for displaying data across multiple views depends on the flexibility of coordination, the expressiveness of graphical encoding, and the ability of users to comprehend the structure of their visualizations as they work. As a result, exploration has been limited in practice to a small fraction of useful visualizations. Improvise is a fully-implemented Java software architecture and user interface that enables users to build and browse highly-coordinated visualizations interactively. By coupling a shared-object coordination model with a declarative visual query language, users gain precise control over how navigation and selection affects the appearance of data across multiple views, using a potentially infinite number of variations on well-known coordination patterns such as synchronized scrolling, overview+detail, brushing, drill-down, and semantic zoom. Improvise has been used to build numerous visualizations for exploring information including election results, particle trajectories, network loads, music collections, the chemical elements, and even the dynamic coordination structure of its own visualizations in situ. This last technique-integrated metavisualization-is unique to Improvise.

Live-streaming platform Justin.tv now supports high-resolution videos using H.264 encoding. The codec, which has made headway in consumer electronics, is also a great format for the Web since it can fit high resolutions in relatively small file sizes--making it ideal for something like streaming. For now there are a few caveats that keep it from being accessible to the average user. For one, videos streamed in high resolution H.264 will not be saved into user archives, and there is no way to do it without using special software to process the stream before it hits Justin.tv's servers. Users are encouraged to be running a rig with a fast processor and modern graphics card, as it takes some considerable horsepower to crunch down video in real time. Eventually the company hopes to offer such processing power on its own servers, so that you'll be able to get similar results with any commodity high-resolution Webcam and a good connection.

At the start of this year, I sat down to write the "Errors and Debugging" chapter of Simply JavaScript. I cracked my fingers, dove into the landscape of JavaScript debugging tools, and emerged very disappointed several hours later. At the time, Firefox was the only browser with a JavaScript debugging tool worth writing about: Firebug. Less than a year later, the landscape has changed dramatically. Every major browser has introduced new development tools that make it easier to diagnose problems with your HTML, CSS, and JavaScript code right inside the browser in question. But can any of these tools stack up against the slick and effortlessly powerful tools provided by Firebug? Let's take a look.

Bringing this down to the bottom line, yet another blogger shares his experience, of watching people bounce away without doing much of anything on his site. How much is traffic like that to a site, and how much will somebody be willing to pay to keep getting more of it? As the author says, "The problem is that when I stumble I am in the mood for some fast action. I don't want to be bothered with heavy reading and just want to be amused." a spirit that, as somebody in one of the sites bookmarked above argues, Stumbleupon's business model gives the company and its management a perverse short term incentive to encourage. But can one encourage impatience and then, moments later, hope that impatience will suddenly vanish the moment a visitor reaches a sponsor's site? Or does behavior, once reinforced, tend to linger? Does the company really expect those sponsors to not notice that their bottom line isn't being helped, just because they hope it will, and assume that it must?
