Search for a command to run...
I have over 40 years of programming experience using a variety of languages over the course of my career to develop real-time solutions for real-world problems.
Keyboards connect us to the world and, as a keyboard enthusiast, I am searching for the ideal keyboard.
Looking at an article for the book “Gist of Go: Concurrency,” I also stumbled across a reference to “High-precision date/time in SQLite” written by the same author, Anton Zhiyanov. I use SQLite in man

Modern Fortran: Tricks of the Software Engineering Trade by Damian Rouson Sometimes I think I'm one of the few programmers routinely using Fortran long after my Engineering studies too many years ago. As such, I'm pleasantly surprised when a new book...
Make GIT a Habit
The more I learn about MQTT, the more intrigued I become. I recently purchased an Arduino Starter Kit containing an Arduino Uno R3, a book with 15 projects, and a variety of sensors, resistors, LEDs and more. I'm anxious to develop an MQTT project and thought it best to start with minimal investment at this time.
A quick search of the Library Manager suggests several MQTT libraries are available:
Visit the Arduino Software page to download the stable (1.8.19), latest release candidate (2.0.0-rc9.3) or nightly builds.
I highly recommend downloading the Arduino IDE 2.0.0 (rc9.3) directly from the Arduino.cc website. As part of the installation process, you will be prompted to provide permission to download libraries to your machine as well, and there are many of them.
Version 2.0.0 is more intuitive and user friendly.

Clicking on the Arduino Uno (COM3)
Right Click and Update the Drivers. Close all windows, reboot your machine.
It worked!
