Adjusting Jupyter notebook Font Size
For screen presentations, I found the original font-size to be too small. Therefore, adjusting the font size permanently would be nice to have. You can do so by adding a custom Cascading Style Sheet (CSS) to your Jupyter configuration directory (usually in $HOME/.jupyter/).

In order to migrate to the latest Python release before the Anaconda Download packages haven been upgraded to it (in my case Python 3.8), I had to first upgrade my Conda installation: And then create a new Python 3.8 environment: Unfortunately, a couple of packages are not yet there, so installing the full Anaconda package …

Globals are not global in Python
Well, the title already says it. Globals are module wide, not global global…. This means, that if you do The global would not change.

Python autocompletion in VIM
Having autocompletion (and some other nice stuff) for Python in VIM is not only a nice feature, but something allowing you to be more efficient when programming Python. First see the result: Youtube: http://www.youtube.com/watch?v=TNMjbaimk9g To make the functionality (and color scheme) available, download the tarball (pythonVim.tar.gz) and extract it in your home directory (i.e. /home/your_user_name), …

Linux: use SSH with X11 forwarding and compression for better performance
To get better performance when using X11 forwarding (either with the -X or -Y option) with a SSH connection, one should enable data compression: $ ssh -X -C -c blowfish-cbc,arcfour to avoid enabling compression with each command, one could enable it permanently in the configuration file ($HOME/.ssh/config): Cipher blowfish Ciphers blowfish-cbc,aes128-cbc,3des-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc Compression yes …
