It is a gloomy day in the Twin Cities of Minneapolis and St. Paul. The good thing is that we have about two days until Thanksgiving Day 2020. This year we are cooking an 11 lbs. turkey. Typically my wife and I make an 18+ lbs. bird. Not only that but we are dropping half of it at our granddaughters place. On Thanksgiving Day we will be connecting with family via Jitsi and Skype.

Hi gals and guys. Hope you are doing well during the COVID-19 pandemic. It seems that most of us are somewhat tired following the basic rules that reduce the spread of the coronavirus. By relaxing the rules in the past few months, the numbers of COVID-19 infections, in most cities worldwide, are going up. Note that the issue is the number of infections, not the number of deaths. Infected people may need hospital services. If the number of patients is larger than the capacity like it was when this thing started, then we have a problem. At this point in time, people with most infections per 1,000, is people in college age. Please follow the rules! We all benefit from it. Continue reading “Print Immutable Linked List in Reverse”
Definitely the weather is changing in the Twin Cities of Minneapolis and St. Paul. Last night my wife and I slept with a windows in the kitchen opened just a crack. This morning the upstairs temperature was at 69F. During winter we keep the upstairs at 68F. Chances are that this evening will sleep with the windows closed and the heater on.
I need to update my post previous post Count Negative Numbers in a Sorted Matrix. I made an incorrect statement and would like to generate an update. If you are curios, I left the body of the post as it was. I generated an opening note. Continue reading “Reverse Only Letters”
It is Monday morning. I got up earlier to finish the code and this post. Hope to be done before 06:00 AM. Today is my wife’s birthday. She is an evening person. Every morning I get up, fix breakfast, and then wake her up.
This year due to the COVID-19 pandemic (thanks China) we have not planned a celebration. Dates tend to shift by a day on non-leap years. Yesterday I received a message with Google photos that we took on yesterday’s date several years ago. Last year for her birthday we were with some family, friends in Rome, Italy. In the evening we all had a nice dinner and walked to the Fontana di Trevi and tossed three coins. That was a nice way to close the day. We like Italy and have been there many times. Perhaps next year things will be back to the new normal and will be able to celebrate once again in Rome. Continue reading “Merge Two Binary Trees – Java”
Earlier today I read the article “Changing the clocks is a bad idea — and it should end, sleep experts say” by Jen Smith, CNN. The article makes a case for the USA to eliminate daylight savings time. It seems there is enough science behind the idea.
I am a morning person. I have a wake up alarm in my smart phone to wake up at 06:00 AM every day. Most of the time I get up about an hour early. Of course, in the evenings my wife and I are ready to hit the sack around 08:00 PM. At the start of summer the sun is up before 06:00 AM. At the start of winter, it is dark around 04:30 PM.
