QED Wiki and the Zend Framework
Filed under: Computers, Javascript, PHP, Programming, Technology, Web Programming
IBM are working on an impressive looking product called QED Wiki, developed with the Zend Framework.
Fundamentally it’s a wiki like any other. But there is a cool layer on top of it that could be revolutionary (although like many Web 2.0 concepts will probably fall short and just be “cool” – we can hope). The interface allows you to create “situational applications” that can link different components together with the ease of a wiki.
It doesn’t really make much sense just reading about it so go watch the video about it.
On a related note, you can now get snapshots of PHP 6.
Audio in Linux

I’ve started writing the page to actually play the audio clips in my language learning app. At the moment it loads the
Flash would be the obvious answer I suppose but I have an uncommon requirement – I need to be able to access the object via Javascript. Specifically, I need to know when a track is finished and the next one begins (from a play list) and none of the freely available Flash media players do that.
Any advice from anyone?
Yet another XML based AJAX toolkit

This one is open source and free.
ASP.NET Atlas really is like Backbase
Filed under: Computers, Google, Javascript, Programming, Technology, Web Programming, XML
ASP.NET might not suck after all. Atlas for ASP.NET is a toolkit for doing AJAXy stuff.
Well in fact it is quite a bit more than that. It has many features of the Google Web Toolkit (except in ASP.NET instead of
Interesting it also has a lot in common with Backbase. It allows you to embed some nifty XML to define a user interface which is then interpreted by the Javascript to render real (X)HTML.
The final irony is that it’s pretty much free. Since it’s .NET, to really use it you need Visual Studio, but the Atlas part itself is free and should be perfectly usable with the Express version of the Visual Studio projects.
Another Firefox cleverity
Filed under: Computers, Javascript, Programming, Technology, Web Programming
A lot of people love Firefox and seems to thin that loving it is "obvious". This is despite the fact that it just eats up memory. Not only that but it keeps it regardless (if you minimise most programs on Windows they free up most of their memory).
There are uses for it, most of them for developers. The DOM explorer and JavaScript debug consoles are absolute necessities. But another cool feature I've found is "View Selection Source". Highlight part of a web page, right-click and you can view the source just for that bit. Yay :)
3D gaming in Firefox and Safari

Okay so "3D gaming" if overstating it slightly, but it's clever.
What's double clever is that you can get a pure JavaScript implementation of canvas for
Now Google push AJAX development
Filed under: Computers, Google, Javascript, Programming, Technology, Web Programming, XML
posted about BackBase, an expensive (for commercial use) AJAX development thingy*. Well Google have produced something similar for free Google Web Toolkit.
Although the end results are the same (as far as the user is concerned) there are important differences. The BackBase software is entirely client side. You write server stuff as normal, output BackBase code and the browser with JavaScript handles everything. The Google system is client and server orientated and odes more work on the server. The server also has to be running Java. It also has better browser support.
This could be a reason for me to learn Java, something I’ve managed to avoid for quite a while now…
* It’s actually an XML based markup language combined with a real time JavaScript processing engine.
Multiple forms in ASP.NET

Essentially all you have to do is load the extra forms using AJAX and I think everything will work.
(I'm working a on a page (not in ASP.NET) that has a table of data with a status column. Each column needed to have a drop down box letting you change the status. Since the number of statuses is large I decided to have a link that AJAXly changed into the dropdown box and a button when you clicked it. Of course you could click all the links and not submit any of the forms leaving you with a page that actually has a bout 30 forms on it.)
BackBase really pushing AJAX

Silly things with JavaScript closures
Filed under: Computers, Javascript, Programming, Technology, Web Programming, XML
JavaScript is immensely cool. You can do some amazing things with it. Although I’m not entirely sure whether you should.
For example I had a bunch of elements on a page I needed to update using
First I replace a simple replace_id function that accepts three arguments. An element id, a URL to GET to replace its contents with and finally a function to be called when it’s all completed.
And then things got silly.
function chain_replace(urls, ids)
{
id = 0;
next_id = function()
{
if (id < = ids.length)
{
return function()
{
replace_id(urls[id], ids[id++], next_id());
}
}
}
next_id()();
}
Now the next_id()(); bit towards the end should be a clue that something a little odd is going on. But I must confirm that this code does actually work. With enough arguments it might make the browser explode with some sort of call stack problem though…
