I like to occasionally brush up on some of the core concepts or do the intro/mid level projects for fun.  Up until recently you could find a lot of the C, C++, Python and  Java projects and their related files at say the 201 or 300 classroom sites. 

is there a new location for these project pages.  It looks like they stopped updating the old ones after the 2013 semester and most of the links are dead now.
