Those nice people at 10Gen, purveyors of finely crafted NoSQL database MongoDB, have announced another free online course: MongoDB for Java Developers (M101J), starting in February.
And hopefully the Java course won't be interrupted halfway through by a hurricane (10Gen are based in NYC)!
Edit: The Python version of the MongoDB for Developers course (M101) is running again from 21 January, as is the MongoDB for DBAs course (M102). See https://education.10gen.com/ for more info.
I agree the Python one is very good. They provide good structure and good hands on exercises throughout. I live in NYC as well. I was impressed at how fast they got the videos up after the interruption of not having power at home or an office to work out of!
