Lots of great talks of which many will be available over at the github repo. I lightning-talked about creating portable applications on Windows using MinGW.
Unfortunately I didn't stick around for the third day, the hack day. Roger seems to have had fun; he used his gcc-fu to get Fortran code to compile against RDKit:
This has surely made Greg Landrum happy as he is on record as bemoaning the lack of Fortran examples in his talks. :-)
...Since no talk about programming languages and computational chemistry is complete without an example of handling legacy Fortran code, this talk will be incomplete; and we can all be happy for that.
The snake that fits your brain: Python for computational chemists, COMP 82, 238th ACS
Looking forward to the next meeting already.
