Both excellent ideas. I'd also like to through my personal favourite
into the mix - memory debugging, cache profiling, heap profiling and
thread debugging all in valgrind.




I'd be very interested in that (as an attempted valgrind user). The debugging one sounds interesting too. A follow up to the databases one (advanced features in FOSS dbs?). I'd potentially be able to give a very limited scope intro do app development using postrgresql in C++ (though my info is probably out of date).
