One thing that can be a bit silly but really works to a degree. Is to dress and act a little bit geeky, do not be shy to walk around with a t-shirt or a hoodie with the python,ruby or some linux logo on it. Talk about software and computing with people you meet. Market your self as a guy that know a lot about software and the word will come around.
I have met several people for example in the gym that have offered me a job or some consulting work because they have seen me with a linux t-shirt on. Of course they did not threw me a job because of the t-shirt but it led to a small chit-chat and then it escalated from there.
