Is anyone interested in recommendations for leveraging Microsoft Entra in OT? I have a few clients going down (or already down) this path.

BTW, Microsoft released a new QR code authentication for Entra last February, which is an excellent fit for operators!

@TimMedin For developers that want to work on my vide, I provide the 2-3 command lines to install the package with Poetry which sets up a venv for development with the extra dev packages installed.

Check out my Github repos and Pypi uploads for ctmodbus and ctserial.

[Justin Searle @meeas]

@TimMedin IMHO, it should be uploaded to Pypi so users can install it in their user account (avoiding OS package interferance). This also allows users who desire to install it in a venv or for Linux distibutions to package it.

[Justin Searle @meeas]

@elonmusk Perhaps you should fire your Cybertruck delivery team too.

We wait 4 years for delivery, but they can't wait 4 days for us to pickup.

Failure to pickup within 48 hours of initial notification puts you back into the waiting list.

[Justin Searle @meeas]

I am proud to say I will fly our R44 home by myself tomorrow after completing my check rate today. It took ten days longer than planned due to bad weather and struggles finding an FAA DPE with availability to do the check ride, but it DONE, and it feels so good!

[Justin Searle @meeas]

This fall, I decided the only way I would get it done was to take the month of January off work and focus on it full-time until I finished my license. So, on January 3, I flew a CFI to our house to fly our helicopter with them to their training center five hours to the north.

[Justin Searle @meeas]

In the summer of 2021, I was able to get halfway through my private helicopter license before the pandemic inconveniently ended, and I had to go back to work. I tried squeezing training flights into my schedule but was not getting enough consistency to make progress…
