I finally had to replace my trusty laptop computer. It was getting pretty flaky. It was an HP Envy 15 which I put into service on September 14, 2017. I got a good seven years of service out of it. I liked it a lot. The replacement is an HP ZBook Fury 16 G11. It has 64 Gigs of RAM (my first IBM PC had 640K). It also has a 1 TB internal SSD hard drive and an Intel Core I9 processor. I have been working on it for a couple days and made the trade out this morning. It is working well enough for the time being, but there is a lot of optimization left to do.
