jQuery special events. Ben Alman’s comprehensive guide to jQuery’s special events API, which allows you to register new kinds of events that can then be attached and detached using jQuery’s bind and unbind methods. Ben’s clickoutside event is a particularly useful example. # 17th April 2010, 9:08 pm

Showstopper! The Improvised Musical. Went to see this last night with some friends—they really do improvise an entire musical (a surprisingly good one, with catchy new songs and three part harmonies) based entirely on user suggestions. They have shows coming up in Brighton and Bath, thoroughly recommended. # 31st December 2009, 9:36 am

UK Scale Camp. We’re hosting a one day web performance and scalability unconference at the Guardian on the 4th of December. If you’re involved in running a high-scale website in the UK (or abroad) we’d love you to come along. Spaces are going fast. # 4th November 2009, 11:12 pm

Where was the ’editorial viewpoint’ at the News Innovation unconference? Martin Belam points out that a problem with unconferences when applied to audiences outside the technology world is that techies who know how the system operates will inadvertently take over the event, skewing the conversation towards technical topics. Not an insurmountable problem, but one that organisers should probably take in to account. # 17th July 2009, 10:52 am

IanVisits: London Events Calendar. Ian Mansfield maintains a superb calendar of cultural (and geeky) events in London. Lectures, tours, bat walks, film screenings... did you know there’s a Festival of Model Tramways this weekend? # 16th July 2009, 7:22 pm

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
