It is very easy with Docker to have a working WordPress up in no time with the official WordPress Image on Docker Hub. If you want to have an image which is backed up properly and that you can migrate w/o any problems on a different machine, you need to take care of the proper volumes mappings. Unfortunately I did not find the proper documentation and I needed to find out the hard way. WordPress Read more…

In [199]: import pandas import matplotlib.pyplot as plt Profits by Country¶ We can get a quick overview with the help of the follwing REST get request. We ask for countries by year Read more…
