Org-mode related prelimnary practices are done here. These includes
two compulational document, one for R, and another for python. It is
possible to merge them together, of course, if needed.

First commit from the magit interface to check the use of the magit
system. Magit requires the updated version of git, thus not usable
with the old version that comes with CentOS7 or before.

The logbook update till module 1 is listed here. Taken from my local org-mode notebook and saved here in markdown formatting.
