Dealing with secrets

GNOME comes with libsecret. You can use libsecret to store your git credentials:

sudo apt install libsecret-1-0 libsecret-1-dev libglib2.0-dev
sudo make --directory=/usr/share/doc/git/contrib/credential/libsecret
git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret

#
# To determine what dconf keys and values to use, you can run `dconf watch /`
# in a terminal as you make changes in settings or tweaks.  You can also use
# `dconf read <key>` and `dconf write <key> <value>` to experiment with various
# settings.  The dconf-editor application is also useful for exploring various
# keys along with their descriptions.

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

def RSI(series, period=14):
    delta = series.diff().dropna()
    ups = delta * 0
    downs = ups.copy()
    ups[delta > 0] = delta[delta > 0]
    downs[delta < 0] = -delta[delta < 0]
    ups[ups.index[period-1]] = np.mean( ups[:period] ) #first value is sum of avg gains
