Web Automation Using Python and Selenium

Selenium is a software library that’s used to automate web browsers. It’s often used to run automated testing but can be used for anything involving a web browser. Since so much software is now running in the cloud and accessible via web interfaces Selenium is ideal for automating lots of manual tasks. There’s libraries available […]

Multi-threading API Requests in Python

When making hundred or thousands of API calls things can quickly get really slow in a single threaded application. No matter how well your own code runs you’ll be limited by network latency and response time of the remote server. Making 10 calls with a 1 second response is maybe OK but now try 1000. […]

Using Python with One Time Passwords (2FA)

Ever wanted to automate a process involving a vendor website and come across this. Me too 😔 One time passwords (aka MFA, 2FA, or two factor authentication as I’ll say from here on) are something everyone should use and are great for security, not so great for automation. Until recently I thought this was hard […]

Why are Logistics Carriers so Bad with Data?

Just to be clear when I say Logistic Carriers I mean UPS, DHL, DSV, GLS and many other three letter companies that deliver your Christmas presents, but in a business context they are also responsible for B2B deliveries of goods to shops and warehouses. I’ve previously worked in Logistics for many years and so have […]

IoT Sensors – Saving Collected Data

Now that my sensors are successfully collecting data and the data is being processed by a Node-RED flow on my Raspberry Pi the final step is to add some persistence to the data. As it stands the data is constantly streaming and being displayed on a dashboard but after that it’s discarded so there’s no […]

IoT Sensors – Data Collection

In the first part I talked mostly about the sensors and the gateway so in this article I’ll show you how to collect, filter and store that data from the sensors. My setup is running locally on my LAN and uses a Raspberry Pi 3B+ to process the data. I’ll be using Node-RED to process […]

IoT Sensors – Getting Started

Introduction I’ve been interested in setting up some home monitoring/automation since getting my first Raspberry Pi a couple of years ago. After using the device for various development projects I finally decided on my first project, try to make a basic home temperature/humidity monitor that cold measure both indoor and outdoors. The idea is to […]

IoT with Node-RED and Python

Now I have two Raspberry Pis running, one as a Bitcoin full node and the other mostly used as a dev/experimentation machine I decided it’s time to put the dev machine to some use. I’d also like to learn more about IoT (Internet of Things) and how they are wired together and communicate so this […]

Introduction to Image Classification using UiPath and Python

After my previous post showing image classification using UiPath and Python generated many questions about how to implement the same I decided to expand upon the theme and give a more detailed description about how to achieve this. My starting point was thinking how I might integrate UiPath with python now that it’s integrated within the platform. I find […]
