Adding a JavaScript-based diff

I’ve been on the hunt lately for some JavaScript based diffing routines.I’ve had a look at a few of them, and the one I’ve settled on is google-diff-match-patch which they use in the Grails wiki! (Thanks Peter Ledbrook for the pointer!) My particular need was around diffing a fairly complex “tree” structure. These tree structures are actually imported from files that 3rd party...

Anyways, I’ve had cause to revisit Spring Security for a new client project, and had some tricky corner cases to solve....

My little project is called “Twitter Until You’re Fitter” and the idea is that I can tweet my weight “@tuyf 93kg” each week, and the app will pick up the value...
