If you are just starting out in development, or have found that your skills are not as marketable as they once were, nothing helps like a certificate in a new, hot field.
I’m not going to go in depth here about the free online certification course Ajax and Web 2.0 Programming (with Passion!) Online Course, because Gene Babon does such a good job of setting this up on his Beantown Web (not just for Bostonians anymore!).
It may be just because they are really good at SEO, but everytime I’m looking for a quick (free) tutorial on something I want to learn about or need a refresher, RoseIndia usually comes up. I think the reason for the quality of most of their tutorials is that they don’t create them all themselves. This is not immediatly obvious, unless you keep looking at other search results for tutorials and find the same one posted in 20 other places. Still, they are good aggregtor for technical tutorials, and for that I definitly recommend bookmarking them.
