Anaconda Python needs cleaning every once in a while

Standard

As a user of Anaconda python I have been receiving (Ubuntu) system warnings of low free space in my home directory. Investigating what was causing this I found out that Anaconda python had several versions of each package. The overall size of the pkgs directory was 14+ GB. After cleaning it is about 3GB.

The second largest directory was my mail in Thunderbird.

So it would be wise, especially if you are limited in disk space, to clean Anaconda. The commands I used are as follows:

 
conda clean --all
conda update conda
# just to make sure nothing is broken and
# your environment is updated
source activate <your-environment>
conda update --all
conda clean --all

Experiments show that what the algorithm picks to show you can affect your emotions. But that’s not all. It also affects political behavior.

R language Development 1997-2015

Video

The open-source world keeps surprising me. It is really amazing how internationally distributed individuals meet and collaborate on open-source projects and develop amazing products that exceed commercially available products. One such example is the development of the R statistical programming language.

Watch the video below and observe how its development since 1997 is similar to the work of ants and bees constructing colonies and hives.
