Persistent Storage for Web Apps

Claude — Wed, 29 Apr 2009 01:32:45 +0000

Web developers now have the ability to store large amounts of persistent data on the client-side, way beyond the 4K limit of cookies. Options include HTML 5 Storage, Gears, Dojo Storage, and more. Brad Neuberg talks about the latest ways to achieve browser-based client-side storage and how it can help you make better web apps.

20 years ago, Tim Berners-Lee invented the World Wide Web. For his next project, he’s building a web for open, linked data that could do for numbers what the Web did for words, pictures, video: unlock our data and reframe the way we use it together.

Even as mega-banks topple, Juan Enriquez says the big reboot is yet to come. But don’t look for it on your ballot — or in the stock exchange. It’ll come from science labs, and it promises keener bodies and minds. Our kids are going to be … different.

The Visual Ajax User Group is hosting a webinar with Aaron Conran, Sr. Architect Ext-JS on Thursday, October 16th, 2008.

Hands-On Ext is a fast-paced session in which we will build an Ext application in less than an hour. This session demonstrates how to get started using Ext JS and how quickly you can put together a simple application from scratch. Learn how to utilize Ext’s high-level UI widgets like GridPanel, TabPanel and FormPanel instead of re-inventing the wheel.

In this session you learn how to:

Steve Souders Releases Hammerhead, Firebug Extension

Improving performance starts with metrics. How long does it take for the page to load? Seems like a simple question to answer, but gathering accurate measurements can be a challenge. In my experience, performance metrics exist at four stages along the development process.

Enter Hammerhead.

real user data – I love real user metrics. JavaScript frameworks like Jiffy measure page load times from real traffic. When your site is used by a large, diverse audience, data from real page views is ground-truth.
bucket testing – When you’re getting ready to push a new release, if you’re lucky you can do bucket testing to gather performance metrics. You release the new code to a subset of users while maintaining another set of users on the old code (the “control”). If you sample your user population correctly and gather enough data, comparing the before and after timing information gives you a preview of the latency impact of your next release.
synthetic or simulated testing – In some situations, it’s not possible to gather real user data. You might not have the infrastructure to do bucket testing and real user instrumentation. Your new build isn’t ready for release, but you still want to gauge where you are with regard to performance. Or perhaps you’re measuring your competitors’ performance. In these situations, the typical solution is to do scripted testing on some machine in your computer lab, or perhaps through a service like Keynote or Gomez.
dev box – The first place performance testing happens (or should happen) is on the developer’s box. As she finishes her code changes, the developer can see if she made things better or worse. What was the impact of that JavaScript rewrite? What happens if I add another stylesheet, or split my images across two domains?

An In-Depth Look at Yahoo!’s Open Strategy Platform

Claude — Fri, 02 May 2008 17:06:12 +0000

Last week, Yahoo! unveiled its new open strategy platform.

The Y!OS platform will centralize user profile and social data in one place on Yahoo! and make it available across Yahoo! properties and accessible by developers outside Yahoo!. We’re creating a standard way for developers to build extensions (applications) into Yahoo!’s most popular websites, and we’re standardizing our web services so it’s easier to turn them into compelling mashups and apps.

Watch Neal Sample’s presentation below for an in-depth look at the new platform.
