I'm trying to set up a software system and part of it is knowing when someone sends Bitcoins to me automatically. I'm using node.js, if that matters to anyone.
How can I programmatically know when someone sends me Bitcoins?

BlockChain.info provides a push notification API: - http://blockchain.info/api_websocket
1That looks very good. Is there also a quick way to take this information to see how many verifications it has? – Beanow – 2012-04-20T08:57:42.993
1Is it possible to do on my own? I mean how does blockchain.info get the info? – Shamoon – 2012-04-25T16:30:03.100
The BlockChain.info api looks cool but what if we want to use TestNet to test? Can we run a service like this on our own box? I was thinking of having a loop polling but wanted to know if there are any better ways. – Keverw – 2012-09-01T11:33:25.757

You could poll the Block Explorer for balance of any Bitcoin address. For example, you can see the page of the address that appeared in the Genesis Block.
1You should try giving more details in your question - will you be using a single address, or generate then on the fly and use them only once? Are you planning on running bitcoind somewhere, or want to have a standalone application? The more you tell us about the constrains of your system the better the community can help you with a solution that is tailored to your needs. – ThePiachu – 2012-04-15T02:17:12.837
