To continue to question further I'm more interested in blogs, websites who once in a while release a tutorial, tip or best-practice on the topics I mentioned. For ex : http://net.tutsplus.com/ is very good website to follow if you wanna learn about or upgrade your knowledge about CSS, HTML, Javascript, PHP .. Is there a website like this for Java and related technologies?
I'll list some of the ones I'm reading, via RSS:
