The tool of choice is mogrify which come from the imagemagic package on your linux platform.

Python's all() function
Python all() function Much of my coding efforts are directed towards analyzing financial data specifically targeting potential cash secured puts or covered calls. Recently, I had to refine some market overview displays. I needed a listing of the current market “gainers” and market “losers”.

"Musings"
Robert Carter III
I happened to see a post on social media that had a picture of a historical marker for Robert Carter of Norther Virginia. The more I learned about this event the more profoundly it struck me.
He was a very wealthy planter in the Northern Neck of Virginia with over 500 slaves. His wealth was inherited from his grandfather (at one time he owned over 1000 slaves but freed some of them while it was still legal to do so) who left large plots of land to his family. He became friends with and traveled overseas with George Washington’s half brother Lawrence who also was a prominent land holder. Robert Carter attended the College of William and Mary and studied law in England.
