Ruby, JRuby, and Rails Application Development (with Passion!)
Starting July 15th, Sang Shin, a Java architect and evangelist from Sun Microsystems, will be leading an online course on developing Ruby on Rails applications, including the use of JRuby. The free course includes 20 weekly lessons (including homework - bah) starting with Ruby fundamentals and working through all the major Rails areas, closing with four complete Rails applications. Of course, Sang will focus the materials on using the free, open-source NetBeans IDE and JRuby runtime.
I'll be acting as an Advisor for the course (the open-source version of a T.A.) along with five other members of a very diverse group. With 998 members and counting, anyone should be able to find a study-group to help out; groups have already formed with cultural themes - Indians, Brazilians, Mexicans, Syrians, etc.
So, if you're interested in learning the nuts and bolts of building a Rails application, join the group by sending an email to firstname.lastname@example.org or visiting the group site.
