I’m listening to this excellent BBC podcast on Unintended Consequences of Mathematics.
In his book The Mathematician’s Apology (1941), the Cambridge mathematician GH Hardy expressed his reverence for pure maths, and celebrated its uselessness in the real world. Yet one of the branches of pure mathematics in which Hardy excelled was number theory, and it was [...]
Okay, I'm currently ripsnort delighted to have found a solution to this problem of rendering SVG element dynamically. As in:
My web apps receive some <svg>...<svg> from an Ajax call ??? Super, there's a drawing on the page!!!

Full drafts are now online for the two big Web Remoting patterns: XMLHttpRequest Call and IFrame Call. There are also a couple of new demos to illustrate GETting and POSTing with both call types: XMLHttpRequest Example, IFrame Example.
A few extracts follow, but first, let me ask you: Do you know of any public IFrame remoting [...]
