Years Asking - #ROS Issue Finally Solved
For years I have asked every human that would listen, why my ROS nodes complain about a shutdown exception. (And I mean **yeeeeeears**. )
Finally asking #GoogleGemini has shown the pattern that should have been in the ROS tutorials all along.
(I have a feeling the "if rclpy.ok():" is actually all that is needed. Have not tested sufficiently yet.)

#Coffee - "An Engineer's Thoughts"
I've been drip brewing fresh ground "Dunkin' Original Whole Bean" coffee for more than 15 years -
With my 2 hard-boiled egg, 1 slice sprouted grain cinnamon bread, 4 strawberries and Cheerios with almond milk - #breakfast.
US$9.33 a bag total brews 89 8-oz cups for a cost of approximately $0.10 a cup.
The #CoffeeBeans have gone up an average of 9% per year for the last five years.
(Comparatively, my weight has "only" suffered 1% inflation per year.)

Turns out the current generation of model based AI cannot tell when it does not know the answer to a question; something humans can tell but prefer not to.
I thought all my robots needed was an #inference engine with #deduction capability.

> Removing PulseAudio..continuing the shift to PipeWire
My #GoPiGo3 robot just shuddered in fear of becoming deaf and mute.

Just finished "Speaker For The Dead", Orson Scott Card.
"Jane" joins my list of "aliens" I'd most like to have as a friend
Somebody else once tried to sell me on "The Truth Will Set You Free"; I'm not buying it anymore, but it sure makes a great read.
(Some "real aliens among us" seem to have special powers against the "speaking of the truth" these days).

@morfic - noticed the #ExtraClass license. Good job.
I keep an #AdvancedClass ticket WB0ZJJ alive from the '70s, but no radios these days.
Thought briefly about investigating #SDR but my focus is really my #robots, with some #running and #biking each week, and #birding with the wife every day.

@fmrico #BehaviorTrees ? I have 50 years of #StateMachine ( for mostly #SerialSystems ) thinking to undo. I haven’t managed personal #BehaviorModification yet.

>"What's on your mind?"
My #TurtleBot4lite arrives today! I participated in the #iRobot #Create3 beta (via #simulation,
they didn't gift me with hardware), so I am familiar with the #robot's lower level #topics, #services, and #actions.My #ROS2 #Galactic #Ignition #Gazebo crashes loading the default #TB4 world.
And TB4 comes up half embedded in an obstacle in the maze world, but managed #dock, #undock, #wallfollow and to drive the TB4lite around with a #teleop_twist_keyboard node.
