David Coallier has two presentations under that general title:
Distributed Schema-less Document-Based Databases
and,
Computational Statistics with Open Source Tools
Neither one of which is a “…death by powerpoint…” type presentation where the speaker reads text you can read for yourself.
Which is good, except that with minimal slides, you get an occasional example, names of software/techniques, but you have to fill in a lot of context.
A pointer to videos of either of these presentations would be greatly appreciated!
