Around a month ago I used Python to brute force the Caesar Cipher (I blogged about it here: https://geektechstuff.com/2019/12/22/brute-force-caesar-cipher-python/). My original solution outputted a solution for each possible cipher shift, which worked ok for small text samples but for larger texts started to take up a large portion of the terminal and my time scrolling. … Continue reading Brute Force Caesar Cipher V2 (Python)
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
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)
Merging multiple PDFs seems to be a common request, and most people don’t want to spend a small fortune on a tool to do the merging. I first looked at this problem with an early Python project (https://geektechstuff.com/2018/02/17/python-3-merge-multiple-pdfs-into-one-pdf/) and later improved on that project by adding a simple GUI (https://geektechstuff.com/2018/07/04/pdf-merge-with-gui-v2-python/). Now I have gone a … Continue reading PDF Merge Website (Python)
I have created a Docker image and now it is time to share a Docker image. I created an image called geektechstuff_flask_hello and it is this image that I am going to share. Log into Docker Via a terminal or command prompt enter: docker login Docker may ask for your Docker account credentials at this point. … Continue reading Sharing A Docker Image
As regular readers may have noticed I use Python a lot and at times I have messed up using differing Python/module versions that did not work too well and then had to spend time unravelling my mess. There are (at least) two solutions to this type of problem: Python Virtual Environment Containerisation Containerisation and Docker … Continue reading Creating A Docker Image
Earlier on today I used Python (via Flask, some HTML and my Raspberry Pi) to help turn my Amazon Kindle into an eInk digital clock. This was cool and I was happy until I decided I wanted to do the same thing via Java and TomCat. For this project I am using: A Raspberry Pi … Continue reading Using a Kindle as an eInk Clock (Java)
A little bit of a mini weekend project today as I wanted to put my Amazon Kindle to use when I’m not reading, and decided that the Kindle’s “Experimental Browser” could be useful. How about an eInk digital clock… Note: I’m using Python for this project but similar results could be attained using JavaScript or Java … Continue reading Using a Kindle as an eInk Clock (Python)
Previously I have looked at Flask (Python) and Django (Python) web servers running on the Raspberry Pi. Today I am going to look at Apache Tomcat, a web server which is more geared towards running Java based applications. I’m currently looking at Java and so will be using the JDK on my Raspberry Pi. For … Continue reading Installing Apache Tomcat / Jenkins (Raspberry Pi)
So far I have looked at outputting the data from my sensors to Flask, Twitter and Azure. However, a simpler option could be to output the date to a CSV (Comma Seperated Value) file that could be used by various programs later on. I’ve placed the Python code to capture data from the Pi sensors … Continue reading Saving Sensor Readings To CSV (Python / Raspberry Pi)
