Java4k and beyond

Hello everybody, I just have problems figuring out pixel by pixel manupulations. I’ve heard of tutorials from ahristov from this thread http://www.java-gaming.org/topics/tutorial-time-sources/16439/view.html but seems like its been down for quite a while. I tried to read the source code myself, but for thye beginner it looks like a mess without comments. I would like to know how binary operations are involved in color manipulations and all. Thank you all in advance.

archive.org seems to have them: http://web.archive.org/web/20120813002359/http://www.ahristov.com/tutorial/java4k-tips.html

Thank you! Hmm, wayback machine refused to work with me.
While you are here, are there more tutorials on such a theme?

I just posted a sample on “shared code”.
