File Hashing in Alteryx

Identifying Duplicate Files Imagine you have a folder full of files, all with different names, where you need to identify which, if any, are duplicates. You could use the file size but it’s not a guarantee the files are exactly the same just because they are the same size. Hashing files is an easy way […]

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 […]

Loading Private Python Libraries to Alteryx at Runtime

The python tool in Alteryx is a great resource that I often use but it can easily get very cluttered with lots of reusable code that could easily be moved out and imported as a library. Unfortunately by default you can’t just use the standard import statement since the location of your workflow at runtime […]

The solutions generally suggest one of two approaches, either Read the file in with an Input Data tool then output again in the new format Use the Run Command tool to use an an Excel component […]

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 […]

Bitcoin RPC Commands over SSH Tunnel

If you’re running a Bitcoin full node and want to run RPC commands against the Bitcoin client from a remote machine the easiest and safest way to do this is using Port Forwarding over an SSH connection. What is Port Forwarding used for? Secure access to a port that is otherwise not listening on a […]
