If open source is too much work, you can also publish in trade journals. For example I published an article on JSR-170 for IBM DeveloperWorks in 2006 when I was unemployed. It took about a weekend to write, and IBM paid me $600 for the piece (and boy was I desperate for the money). I had companies asking me for interviews within days due solely to that article. The oddest thing is that I continue to get interview requests from that piece (and a few from PHP Architect), even though it was written in 2006.
By the way, the reference to "SoloFX Enterprises" is fake. As I said, I was unemployed at the time, so I just made something up. You'll find several other articles from me right around the same time period.
