Well, it's been a few weeks since I released LastGraph upon the world, and around a week and a half since I posted it to the Stats group on last.fm in an attempt to get some users.
Well, it certainly worked.
As I write, it's already passed the 2500 graphs mark, and that was after the counter was reset during an upgrade, so it's actually a few hundred more. People just keep coming, from various places; I've taken to having a Google Alert on the term 'lastgraph', to get some idea of how it's spreading.
Thankfully, the current hardware is just about up to the load. Over the past few days, I've got the site off a very old SQLite and onto a MySQL database; this means I've been able to bump up the number of webserving threads from one to around 30 (yes, the old sqlite wasn't threadsafe). I've also improved the graph colouring, and the renderer itself, to make them more efficient and portable.
I'll soon be releasing a lastgraph render client to the world, so anyone can contribute CPU time to the good cause of making pretty graphics; hopefully, I'll be able to keep up with the rising number of users that way, and perhaps even be able to give my laptop a rest every now and again.
Email notifications were added this afternoon, so now you don't need to remember to visit your user page all the time.
You're all doing a good job of promoting it, anyway. It's unnnervingly satisfying to check the queue and see that over a hundred users have suddenly appeared out of nowhere. My last.fm profile's shoutbox is getting the workout it never deserved, and things are generally going pretty well.
There is still work to be done; adding more nodes, adding more options, and trying to make even nicer graphs. But, still, it's come a long way in a few weeks, and I'm very happy about this. My host may not be, but a gigabyte of bandwith a day isn't that much transfer, really...
