REST API

It is another average fall day in the Twin Cities of Minneapolis and St. Paul. It is sunny and cold. Two more days for the weekend; not that it matters because we are still in the COVID-19 pandemic. That said things appear to be getting better. Hopefully a vaccine will be available soon and we will all get into a new normal.

During breakfast my wife asked if windows were closed and the furnace was on. I told her about my midnight adventure. We agreed on leaving windows closed from now on until next spring. The system at home has an air exchange unit so it makes sense to keep the windows closed and the temperature at 68F. Continue reading “Number of Islands – Java”
