Creating a github repo from the command line and setting up https protocol
  • create a repo via the command line: hub create
  • it's possible to connect with github via a number of protocols, like ssh and https. In order to have https as the default: git config --global hub.protocol https
  • in order to push to a given repo once 2FA is activated via https, it's necessary to generate an access token and use that as the password instead of the login password for the user

### MATPLOTLIBRC FORMAT
# This is a sample matplotlib configuration file - you can find a copy
# of it on your system in
# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it
# there, please note that it will be overridden in your next install.
# If you want to keep a permanent local copy that will not be
# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux
# like systems) and C:\Documents and Settings\yourname\.matplotlib
# (win32 systems).

Solve ft_render error in octave, by installing fontconfig with universal support. Gnuplot makes use of fontconfig to display fonts.

In order to install octave with support for free type fonts when plotting it is necessary to install fontconfig with universal access, which builds a universal binary. Otherwise the following error is returned:

warning: ft_render: unable to load appropriate font
warning: could not match any font: *-normal-normal-10

Gnuplot makes use of fontconfig to display fonts. So first install fontconfig: brew install fontconfig --universal. Then install gnuplots: brew install gnuplots --with-qt, the flag --with-qt refers to the gui interface which you're willing to use
