jQuery: Changeset 5990. “Added a new liveQuery/event delegation hybrid method”. Lets you add events that continue to work as new elements are dynamically appended to the DOM, e.g. $(’div p.foo’).live(’click’, fn). Works by adding an event handler to the root document element itself and relying on event bubbling. I have to admit I preferred the earlier proposal of $(’div’).delegate(’p.foo’..), which feels like it should have much better performance—anyone know of a good plugin that supports this? 23rd December 2008, 12:22 pm

Visual Event. External code loading bookmarklet that visualises the JavaScript events hooked up to the current page, and lets you view the source code of the event handling function for each one. Only works for events added by jQuery, YUI or MooTools since those libraries maintain a cache of event handlers that they add, to work around the standard DOM’s omission of handler introspection. 10th December 2008, 3:38 pm

Skillswap goes Portable. Skillswap Brighton will be addressing OAuth and Data Portability on Wednesday. I’m annoyed to be missing it. 21st November 2008, 10:25 am

Freebase Hack Day. I’m finding Freebase increasingly interesting at the moment, and their public hack day on the 8th November in San Francisco looks like it could be a lot of fun. They’ll be previewing Acre, a new server-side JavaScript application platform targeted at building Freebase powered applications. Hit “view source” at the bottom of the hack day site to see what an Acre app looks like. 24th October 2008, 12:06 am

Mark Zuckerberg speaking at FOWA. The Future of Web Apps Expo is just a few weeks away, and Mark Zuckerberg is the surprise keynote. I’m chairing the developer track again this year. 24th September 2008, 1:11 pm

Open Tech 2008—5th July in London. Awesome—I still have happy memories of the last Open Tech (back in 2005), very excited about this one. Once again, it’s only a fiver to get in. 18th March 2008, 1:03 am

Good architectural layering, and Bzr 1.1. Mark Shuttleworth on the growing importance of plug-in architectures as an open source project evolves, as they allow new developers to release their own components without needing commit access to the project. Django is pretty good for this, but more hooks (and a faster event dispatch system) would be useful. 9th January 2008, 2:06 pm

HTML5 Media Support in WebKit. WebKit continues to lead the pack when it comes to trying out new HTML5 proposals. The new audio and video elements make embedding media easy, and provide a neat listener API for hooking in to “playback ended” events. 12th November 2007, 11:21 pm

JavaScript Madness: Keyboard Events. Keyboard events in JavaScript are a total pain. This looks like a pretty comprehensive reference to getting them to work cross-browser. 9th November 2007, 11:07 pm
