Flockr generates digraphs out of your flickr contacts. This is what has triggered me to go off the straight & narrow path of low level programming into hacks with Graph networks and x-mixed-replace. Anyway, what is done is done - take a look at a canned demo if you are on Firefox 1.5 and above (can't host cgi scripts).
The really hard part of the above code comes out of the simple fact that HTML Canvas is totally pixel based. You cannot attach an event to a small circle drawn as lines & figures. The code inside graph.js has a class called NodeHandler which sort of implements event masks and handlers for a node I've drawn on canvas. The code uses a hashed bucket to determine which all nodes it needs to iterate over, rather than loop over every node in the graph for every mouse move - harsh lessons learnt from dotgnu's winforms. It works better than I'd expected of Javascript and certainly seems snappy enough.
Now, I'm off hacks for a while ... time to vent some energy on real code.

The LCA submissions have been rated, reviewed and the letters sent out. And it shouldn't come as a very big surprise that my talk hasn't been selected - here's to all those who said "Yeah right, save your talks for real conferences". I can't honestly say that I'm not disappointed, mainly because there is no point in talking about libjit in 2008 - it would have crossed over the bump into old & busted. And I'm definitely not going to submit a talk to conference which I haven't attended - I'm too fragile to go through an audience mismatch again.
But on the other hand, it is a testament to the quality of conference. if my talks aren't good enough, that sure is a conference which I shouldn't miss - which brings me to the real reason why I'm depressed right now.
My LCA 2006 trip in total cost around 1.4 Lakhs (~3200 USD) - of which dotgnu chipped in 1700 USD, Yahoo! chipped in 600 USD and I pulled the rest of the ~1000 USD. But this year, I see no reason for DotGNU to pay anything, because most of my efforts have gone into APC rather than the usual creative energy vented out on dotgnu. Since I have switched teams & manager, I think Yahoo! will wash hands clean, especially after what happened to spo0nman.
Since I'm not getting a raise this year, despite complaints, I don't think I can build a slush fund to fulfil the extra ~2000 USD (7 months' savings) - but even for the 1000 USD part, I'll probably have to give up a few luxuries. There's a bit of me that says I should be more optimistic, but deep inside me I know why I'm not.
