Python Tutorial – CS50

It is Thursday April 23, 2020 and in the Twin Cities of Minneapolis and St. Paul we are still in lockdown for the COVID-19 pandemic, but with some eased restrictions. The Federal Government has defined a very specific set of steps to gradually lift the quarantine in the country. Now it is up to the different States to apply the rules as they fit. If there is a recurrence then the state MUST go back to square one (full quarantine) and repeat the process somewhat slower in order not to overtax the healthcare system.

Robot in a Grid

This past weekend my wife and I spent time looking for protein-rich groceries. We were attempting to get those and additional items for a few families that wish to stay in lockdown despite the governor of Minnesota starting to relax the lockdown. The current orders went into effect last Saturday April 18, 2020 at midnight. Among the main items is that people in the state can go golfing and shooting in open ranges. Both Saturday and Sunday were sunny days. We could tell for the number of cars and people walking the dogs, jogging and just strolling that many people took advantage of the new rules.

On our side we will continue to try stay home as much as we can by limiting trips to the grocery stores and continue to use Jitsi to communicate more often with family and friends. Continue reading “Robot in a Grid”

Missing Number – Revisited

It is Friday, April 17, 2020 and the COVID-19 pandemic is still around. It seems like China is responsible for this pandemic that has affected the entire world. It is a shame that China put the lives of thousands in front of their reputation and ambitions. Hopefully the world will stop manufacturing products in China. Remember that China copies and steals all product and manufacturing technologies they collect from foreign companies manufacturing there. Continue reading “Missing Number – Revisited”

Compose Ranges

It is a rather cold spring day in the Twin Cities of Minneapolis and St. Paul. I believe there is a winter storm warning for today all day. This morning when I got up, there was a thin coating of snow on roofs and lawns. The roads seem to just be wet. One way or the other my wife and I are not planning on going out. We are under lockdown due to the Wuhan virus (also known as COVID-19) pandemic.

Besides work I have been taking a few courses, reading technical documents, reading non-technical stuff and watching the news. As of today April 12, 2020 in Dakota County, MN (I live in the city of Apple Valley which is in Dakota County) the total number of deaths attributed to the pandemic in

Dakota County is 4 which represents 0.001% of the population. The previous count of 3 held for several weeks. In the USA the total number of deaths is 20,411 which represent 0.006% of the population of about 330 million. Seems like in this area we are doing well. No matter which city or country you live in, please keep social distancing and do not leave home unless it is needed. In order to beat the pandemic we all need to follow social distancing until a vaccine is available or until the CDC (do not trust unofficial sources) informs us that it is safe for people that have antibodies for them to resume normal activities.

Contains Close Numbers

It is another COVID-19 (Wuhan virus) pandemic day. Seems like the stats for Minnesota and Dakota Country, the county I live in, are not increasing out of control. As a matter of fact they might be in a plateau. As we speak Minnesota has 34 total deaths which represents .001% of the population, and Dakota County continues to have 3 deaths which represents .001%. Best wishes that things are getting better where ever you are.

Italy is already talking about different ways to get people back to work. Hopefully they can do it in the near future. The United States will hopefully also get back to normal in a month or two. Failure to get the economy up and running will have very bad repercussions. Let’s continue to keep social distance and slow down new COVID-19 cases. Continue reading “Contains Close Numbers”

Graph Breadth First Search

I had to add a few paragraphs before finishing this post. My wife called me to go up to have lunch. During the COVID-19 pandemic, during the workweek, I help my wife with some lunch items just like I do on weekends. Today I made open face toasts with avocado; simple and delicious.

First take a couple ripe avocados, cut them in half and remove the pits. Then peel them. Leave them alone until the toasts are ready (about 3 to 4 minutes).

Today I used four slices of brioche bread that we purchased at Trader Joe’s a week ago. If you are not familiar with brioche, it is fluffy and somewhat sweet. Our bread loaf has been used and is still sitting in the refrigerator.

I pulled out our panini press (a.k.a. Breville Smart Grill & Griddle) and set it to start warming up to 400 F. Any electric grill, waffle maker or plain pan can be used as a substitute for a panini press. Continue reading “Graph Breadth First Search”

Graph Multiple Costs

Due to the Corona Virus or COVID-19 the entire world is experiencing situations that we have never seen before. The Internet, TV and other news sources are full of reports. Some of them have good and valuable information while most are just opinions which have no scientific background. We should seek information from reliable sources and when possible check our findings against multiple reliable sources and use common sense, which as we know is not the most common of the senses.

Yesterday evening I started this post and wrote about two pages regarding COVID-19. Today started reading it and decided to delete them with the exception of the first sentence. There is already too much information out there. Please stay home. If you need to go out for groceries, please keep social distance. Healthcare facilities are already taking care of more patients that they were designed for. Continue reading “Graph Multiple Costs”

FFT – Business After COVID-19

This is the first post of a set which I am calling “Food for Thought”. The main idea of this blog is to describe and possibly discuss things of interest to computer scientist and software developers. Occasionally I run into topics for which I would like to generate a post. You should be able to identify them quite easy for the first three letters “FFT” which I will include in all the titles lacking technical content. Continue reading “FFT – Business After COVID-19”

Sherlock and the Valid String

It is Sunday March 15, 2020 and it is a sunny day in the Twin Cities of Minneapolis and St. Paul. The current temperature is about 22 F. It has gone up a few degrees since I woke up today. The high is expected to be in the low 40’s. It seems like it is going to be a nice warm winter day.

It has been a crazy week. The count of confirmed COVID-19 cases in MN according to the StarTribune up to last Friday was 9. That said; my wife and I decided to get some supplies (e.g., two packages of toilet paper at Costco) and remain at home (with a few exceptions) until the pandemic is under control. I will write a set of posts regarding COVID-19 in a separate category. Continue reading “Sherlock and the Valid String”

Sherlock and Anagrams

The news is full of articles and posts about the corona virus. Before getting in panic mode, stop by the CDC “Coronavirus Disease 2019 (COVID-19)” web page and get informed.

My wife and I follow and watch several YouTube channels. We are mostly interested in foods to prepare and consume and places to visit on our next holiday. Yesterday we watched a new episode on one channel that deals with food and travel in Sicily, Italy. The channel is hosted by a couple of Americans that have roots in Europe and Italy.

They had some interesting facts about how to make a disinfectant using alcohol, aloe vera and some scents. I was not going to mention the specific video, but as I am going over this post, I feel that it is missing. The video is named “SPECIAL EDITION: Coronavirus update from Sicily!”. Quite appropriate for the times we are living in. Continue reading “Sherlock and Anagrams”
