"On mobile devices, the Web hasn't lived up to its promise of a universal programming foundation. Google is trying to change that." Android hogged the spotlight at Google I/O, but performance improvements in Google's Chrome browser show that the company hasn't given up on trying to advance its other programming foundation -- the Web. The mobile version of Chrome has become much more responsive since 2013, said Paul Irish, a developer advocate on the Chrome team, speaking at the San Francisco conference. "We've improved the speed of animation by 75 percent and of scrolling 35 percent," Irish told developers Thursday. "We're committed to getting you 60 frames per second on the mobile Web." That performance is crucial for persuading people to use Web sites rather than native apps for things like posting on social networks, reading news, and playing games. It's also key to getting programmers to take the Web path when so many today focus on native apps written directly for Google's Android operating system and Apple's iOS competitor. The 60 frames-per-second rate refers to how fast the screen redraws when elements are in motion, either during games or when people are doing things like swiping among pages and dragging icons. The 60fps threshold is the minimum that game developers strive for, and to achieve it with no distracting stutters, a device must calculate how to update its entire screen every 16.7 milliseconds. Google, whose Android operating system initially lagged Apple's rival iOS significantly in this domain of responsiveness, has made great strides in improving its OS and its apps. But the mobile Web hasn't kept pace, and that means programmers have been more likely to aim for native apps rather than Web-based apps that can run on any device. ............................ Good review focused on the growing threat that native "paltform specific" apps are replacing Web apps as the developer's best choice. Florian thinks that native apps will win

"The Sun Labs Lively Kernel is a new web programming environment developed at Sun Microsystems Laboratories. The Lively Kernel supports desktop-style applications with rich graphics and direct manipulation capabilities, but without the installation or upgrade hassles that conventional desktop applications have. The system is written entirely in the JavaScript programming language, a language supported by all the web browsers, with the intent that the system can run in commercial web browsers without installation or any plug-in components. The system leverages the dynamic characteristics of the JavaScript language to make it possible to create, modify and deploy applications on the fly, using tools built into the system itself. In addition to its application execution capabilities, the Lively Kernel can also function as an integrated development environment (IDE), making the whole system self-sufficient and able to improve and extend itself dynamically....." Too little too late? Interestingly, Lively Kernel is 100% JavaScript. Check out this "motivation" rational: "...The main goal of the Lively Kernel is to bring the same kind of simplicity, generality and flexibility to web programming that we have known in desktop programming for thirty years, but without the installation and upgrade hassles than conventional desktop applications have. The Lively Kernel places a special emphasis on treating web applications as real applications, as opposed to the document-oriented nature of most web applications today. In general, we want to put programming into web development, as opposed to the current weaving of HTML, XML and CSS documents that is also sometimes referred to as programming. ...." I agree with the Web document <> Web Application statement. I think the shift though is one where the RiA frames web documents in a new envirnement, blending in massive amounts of data, streaming media and graphics. The WebKit docuemnt model was designed for this p
