Jenkins is a tool to help with Continuous Integration / Continuous Delivery (CI / CD). I originally looked at installing Jenkins as a Java web app on my Raspberry Pi during this post: https://geektechstuff.com/2019/05/26/installing-apache-tomcat-jenkins-raspberry-pi/ . I am now hoping to expand a little bit more on using Jenkins by building a freestyle project that connects to … Continue reading Jenkins – Connecting To GitHub and some Python
In my previous post I looked at turning an image (in this case XKCD #1696) into it's pixel values. Now I am going to take the CSV of values and turn them back into an image. The Python for this function (including the Python for the functions to turn the image into a CSV from … Continue reading Turning A CSV Back Into An Image (Python)
Open CV (https://opencv.org) is a library available to Python (and other languages) to assist with image based machine learning. I am looking to turn an image into pixel values and then turn a file of values back into an image.

Imagine that you are a software company and host an awesome free piece of software. One day your site is hacked and the download file for your software is replaced with a malicious version of the software. It might be days (or longer!) before you notice. Or what if someone is intercepting traffic and altering … Continue reading SHA256 File Hash Values And How To Check Them (Raspberry Pi / Mac OS X / PowerShell)
When you connect to a system via SSH a banner of text is displayed. Today I am going to look at changing the default SSH banner text on my Raspberry Pi 4 (Raspbian Buster). The default Raspbian Buster SSH banner looks like this: This banner contains: Information about the system via Pluggable Authentication Modules (PAM) … Continue reading SSH Banner Text (Raspbian)
PowerShell Core is a version of PowerShell that can be installed on Windows, Mac OS X (I covered it here) and Linux, i.e. Raspbian.

I tackled some of the basics of Git / Git Hub in my previous blog post. Today I am going to look at Ignoring and Logging. Git Log Navigate to a folder that is git repository and run the command: git log This command should make the terminal output the history (i.e. all the changes) … Continue reading Git Ignore & Git Log
Today I am looking at some commands to quickly get up and running on GitHub using a Raspberry Pi. The same instructions should work within other Linux based terminals and Mac OS X (minus apt-get). Wikipedia says that Git is: "...a distributed version-control system for tracking changes in source code during software development.It is designed … Continue reading Introduction To GitHub (Raspberry Pi)
I regularly use SSH (Secure Shell) to control the various Raspberry Pis that I have set up as none of them are connected to a monitor / keyboard / mouse and it provides easy access from my laptop. Note: The first piece of advice when using SSH with Raspbian is to make sure the default account … Continue reading Changing SSH Port (Raspberry Pi)
