Encode and Decode TinyURL in Java

It is Sunday morning again. It seems that time is flying by faster than ever. Yesterday I worked all morning (about 6 hours). My daughter in law was going to visit her family and my son had to stay home. They were expecting a delivery and installation of a piece of exercising equipment. The delivery was scheduled between 03:00 PM and 06:00 PM.

Rectangle Overlap

There is some severe weather in the Texas area which should affect the Twin Cities of Minneapolis and St. Paul later today and tomorrow morning. Hopefully it will not be too bad.

On the local news members of the Black Lives Matter movement vandalized and looted several blocks of tall buildings in the down town of the Minneapolis business area. Not sure what was the point of the protests which just create problems for regular people that work and live in that area of the Twin Cities. This time around, the mayor of Minneapolis and the governor of Minnesota immediately called for the Minneapolis police, Minnesota State troopers, and National Guard to stop the vandals and looters. Will see how this sage develops in the next few days. Continue reading “Rectangle Overlap”
