In this section, we are going to show how to run a python script as a systemd service, allowing you to boot it at the start of a Linux machine and to maintain it alive.

We are going to use a very basic Telegram bot in order to test that our script will:

1. Automatically start when the machine boot
2. Automatically restart when it crashes/exits for whichever reason

TA-lib requires 2Gb of RAM. You can either:

1. Upgrade your VM to a 2Gb RAM VM
2. Use this guide to create a SWAP file (virtual memory) on the VM's SSD that is at least 2Gb: https://www.vultr.com/docs/setup-swap-file-on-linux

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.
