It is Friday and not a hot as it has been in the couple last weeks. The forecast calls for a high around 88F. We will see if the forecast matches the observed temperatures for the day.
The cleaning lady and crew are expected today. Apparently last week she had some issues which ended in a no show.
Due to the fact that I usually talk on Fridays at 07:00 AM with a friend that we met while attending elementary school, my wife and I decided to postpone our daily walk to around lunch. It turns out that my friend had to get up quite early today and travel for business for about two hours. We both are morning people but getting up around 03:00 AM to chat is not acceptable.
Since the cleaning crew will be leaving around lunch time, and my wife and I will go out for a walk, she will not have time to cook lunch which is our main meal of the day. On our way back I will pick up a bag of Asian food from Trader Joe’s which we keep in the outside fridge. Hopefully it will be Kung Pao Chicken. It is our favorite. That said; we typically alter the meal to our taste by adding different things (i.e., chicken broth, unsalted peanuts).
Yesterday I read a very interesting article on IEEE SPECTRUM titled How Software Is Eating the Car. The complexity of software and the amount of features depending on it is growing exponentially. I have had the opportunity to owning several German made cars and have experienced the increase of features and hardware referenced in the article.

It is another nice and hot spring day in the Twin Cities of Minneapolis and St. Paul. Yesterday after work my wife and I headed to the bank. On our way back I noticed that the temperature had gone up to 99F.
Earlier today after breakfast my wife and I went out on our daily walk. There were more people than usual. We stopped to talk with a neighbor that was also out and about. She likes to walk at a good pace. She was covered in sweat.
The forecasted temperatures for the next couple weeks will are in the mid 80s to the mid 90s. During lunch time the temperature went up to 93F. In general the high temperature for the day occurs around 05:00 PM.
A couple weeks ago we were talking with a couple of neighbors. They mentioned that some of our plants in the front yard were dead. Today during lunch the company that handles plants and lawns stopped by to remove and replace all the dead shrubs.
On a separate note, things are not going well with the vote counting process. There seems to be a lot of cheating going on. It seems that the candidate that represents communism and terrorism will get elected president. The economy has come to a standstill. The Peruvian currency is devaluating.
In addition the candidate from the left is instigating people to go after the upper and middle classes. Hope this things is resolved peacefully in the next few days. Continue reading “Grid Traveler – Tabulation”
Good day! It is a Friday in the month of May. The forecast called for rain and thunderstorms. We only received some rain. It is good to have some rain because things were starting to dry up. When vegetation dries up it may catch on fire.
In this post I will attempt to solve two flavors of the same problem. I believe one can create a few more problems by changing just a few words in the requirement. This will become clear as we read the requirements and describe the differences.
I found this problem named Movies on Flight in the LeetCode web site. Apparently Amazon has been using different versions on some of their technical assessments. Continue reading “Movies on Flight”
Good morning gals and guys! Hope you day has started on the right note. Today in the Twin Cities of Minneapolis and St. Paul we are expecting a high temperature of 67F and the day is sunny. Starting today the two-week forecast shows high temperatures in the upper 60’s to mid to lower 70’s. All looks nice, but we are somewhat low on precipitation. From my backyard I can see a small pond with very low water levels. Hopefully farmers are receiving enough rain to have a good crop this fall.
This morning I watched a session from AWS Summit Online. The session is named “Amazon DynamoDB: Untold stories of databases in a serverless world” by Angela Timofte. She is a data platform manager with Trustpilot. What called my attention were a set of points she brought up which illustrates how important is to allow your technical staff to experiment, learn and make mistakes. Such approach has helped the company move from MySQL to MongoDB and currently to DynamoDB. What is more important, the company currently uses about ten different database engines to store different types of data. They are using the right tools for the jobs (one size does not fit all). If you get a chance take a look at the 22 minute presentation here. Continue reading “Symmetric Tree”
