Hi Ben

Once I got my first Raspberry Pi I had to learn Ubuntu, Docker (my one experience of Docker on Windows had not gone well, however, Rich Taylor took exactly 30 minutes to convince me that having 15 IRIS or IRIS for Health containers in Docker for Ubuntu on his Raspberry Pi farm was a very good thing indeed). The introduction of Python, both Native and Embedded along with R and Julia had me scurrying off looking for quick ways to get up to speed on the basics. I invested in a Samsung T5 500GB SSD drive and I studied a couple of articles on the web on how to get my Pi's to boot from a USB SSD only to realise that the people who had followed his instructions ended up with a sticky mess. In the end, I just used my laptop to clone the Micro SD to the SSD and even though it left most of the SSD unallocated which 3 different windows partitioning tools along with the built-in windows diskpart and computer components tools couldn't solve, as soon as I connected the SSD to my Pi and booted from the SSD, Ubuntu very nicely went and expanded the partition for me. I could have used GParted to create more partitions and I suspect that I could probably create 3 separate boot and data configurations for 3 Pti's with a bit of thinking and planning. However, I digress, everywhere I went on this journey I came across cheatsheets for everything and not just programming. I mean everything. There is even a Cheatsheet Site that runs competitions for the best cheat sheets in terms of style, usefulness, readability, sensitivity to people who can't see colours very well.  Then Yuri published a DC Post on seeing IRIS through the TOGAF model and he did a great job so I asked him if I could add it to my collection. My aim is to get DC members who a really fond of some particular aspect of ObjectScript, or Adapters, or Devices, or IRIS HL7 and IRIS FHIR to create cheat sheets which I will collect into one volume and have them styled in ISC colours and logo's and add them to the ISC Learning, Documentation, Global Masters repertoire.

So by publishing my article and attaching the Python examples I hope to inspire other DC members to start contributing.

Hi David

This is a great article. I am currently working for a company that has used the task manager as a fundamental part of the application architecture. If I had been involved in the design of their application I would probably have used an Ensemble Production with services for each automation and then specify a time when the service should run. The application I am working on has given me a whole different view on how the Task Manager can be used so your article couldn't come at a better time from my point of view.
