AWS EC2 instances can be powered off (or on) via a few lines of Python and the Boto3 library. Below is an example I'm currently playing about with. The instances segment filters on all EC2 instances that are running and contain a tag of "office_hours", great to run at the end of the day to … Continue reading Powering Off AWS EC2 Instances via Tags (Python)

Grafana – Using An API Call To Add DataSources (Python)
I've written blog posts on how to install Grafana and data exporters using Ansible (https://geektechstuff.com/2020/06/25/grafana-prometheus-and-node-exporter-on-raspberry-pi-via-ansible-raspberry-pi-and-linux/) and a blog post on adding users to Grafana using an API call (https://geektechstuff.com/2021/01/06/using-an-api-call-to-make-multiple-grafana-users-python/), but after re-reading my blog posts I decided to automate the process (previously a manual step in the Ansible post) of adding data sources.

Beyond The Basic Stuff With Python – Book Review (Python)
Over recent years my skills with the Python language have grown. This has been down to self-learning, online courses and several excellent books. However, at times I get the feeling that my Python skills are lacking the finesse and finish that other programmers have. Is it because my skills are missing something? If you get … Continue reading Beyond The Basic Stuff With Python – Book Review (Python)
Tackling Fractions With Python
Fractions, not something I've really looked at since my school days.

Note: https://www.calculatorsoup.com/calculators/math/fractions.php provides an online calculator to help with fractions.

Using An API Call To Make Multiple Grafana Users (Python)
A little while ago I looked at using Grafana on a Raspberry Pi ( https://geektechstuff.com/2020/06/25/grafana-prometheus-and-node-exporter-on-raspberry-pi-via-ansible-raspberry-pi-and-linux/ ), today I created a quick Python script to create new Grafana user accounts using the Grafana API. Why Use The API? Grafana does have a graphical web based interface for creating users, and if creating a single user account … Continue reading Using An API Call To Make Multiple Grafana Users (Python)
Real World Python – Book Review (Python)
However, I also have periods where a form of writer’s block kicks in and wonder, “What else could I use Python for?”. As if by magic, Lee Vaughan has answered with “Real World Python” which contains examples of real-world problems being answered by Python and then expands on the solutions with fun challenge projects and further reading.
Caching Requests (Python)
Python's Requests module is a great way for interacting with data over the internet, however when designing/building a Python program that uses Requests that can mean lots (and lots) of Request calls to test a function. This is not too great if you are testing over a poor internet connection, or on limited bandwidth or … Continue reading Caching Requests (Python)
