Today is Christmas Eve Day 2020 and we woke up with -3 F. In addition snow and wind started yesterday afternoon. Looks like a perfect day to stay in and roast a turkey.
As a matter of fact, my wife and I prepared the turkey early this morning and put it in the oven. The raw turkey came in at 24 lbs. It had giblets and a bag of liquid for basting. We disposed of those items. Next time we roast a turkey will get a smaller one (about 11 lbs.) and from a different brand (not Jennie-O). The breast of this turkey is not in proportion to the weight. Will see how the sandwiches on ciabatta bread turned out later this afternoon. Continue reading “Design HashMap – Second approach”
Good morning. Hope your day is starting on the right note. Yesterday was a long and busy day. Something at work stated on Saturday extended at least through yesterday. I spent a lot of time on the phone, browsing code and looking at log files. It seems we know what is causing the problem. Currently I am in the midst of formulating approaches to address the issue. Hopefully all will be solved by tomorrow.
On a separate note, yesterday I had the opportunity to meet on-line a software engineer that works at a large software company. You never know what the future has reserved for you. Continue reading “Spiral Matrix – Revisited”
In the past three days the high for the day has been in the mid to upper 40s. Since late fall a considerable amount of leaves has been accumulating in the entrance at home. Yesterday just before lunch I picked up the dead leaves. This morning some started to collect. I guess this is due to the orientation and shape of the entrance.
Last evening I also read an interesting article titled After Centuries, a Seemingly Simple Math Problem Gets an Exact Solution by Steve Nadis published in Quanta Magazine. Apparently a German mathematician named Ingo Ullisch figured out an exact solution for a problem. Good for him. What I liked more than the problem or its solution is the last paragraph in the article. In my humble opinion, this reaffirms the fact that reading and experimenting is the best way to learn.

It is a Monday morning and it is garbage collection day so I had to put out on the driveway both bins. The company that provides our development with the service collects every week both garbage and recycle bins. All previous companies that I am familiar with collect garbage every week and recycle every other week. To be honest with you, my wife and I would be fine with recycling once a month and if it was not for the potential for smell during summer, garbage every other week.
Earlier this morning, I saw in my inbox a recommendation for a problem from HackerRank named Sherlock and GCD which maybe solved with a Dynamic Programming approach. Continue reading “Sherlock and GCD”
Good day! Hope you are doing well. Apparently the number of COVID-19 cases in the Twin Cities of Minneapolis and St. Paul has risen. In addition it seems that the number of free ICU beds had dropped closely to 0. This implies that a person who falls sick and needs intensive care might have a tough time finding an available bed. For our own sake, please follow distancing rules and keep safe. We all will benefit from such behavior.
I have been looking at some problems in a Facebook portal. They are intended as exercises for technical interviews. Continue reading “Number of Visible Nodes”
It is Tuesday November 03, 2020 and it is Election Day. As it is customary my wife and I got up at 06:00 AM. I prepared our usual breakfast (yogurt, mixed fruits, homemade granola and bananas). We have been preparing the same breakfast for a decade or so.
After breakfast, we both got ready and headed to our designated polling location. There were two lines. Both were moving at a reasonable rate. Once we got our ballots we filled them and inserted in the counting machine. We were at the site for about 15 minutes. All went as expected. Continue reading “Angle Between Hands of a Clock – Java”
Hello there. It is another Sunday morning during the COVID-19 pandemic. The current temperature in the Twin Cities of Minneapolis and St. Paul is about 30F and is sunny. As soon as I finish with this post my wife and I will stop by Target to get some sundries.
Yesterday my wife and I met my older son at Costco in Minneapolis. We get together every other weekend at Costco to do groceries. My wife and I got a 35 lbs. of beef chuck cut. Once we got home we cut smaller manageable portions, put them in bags and placed them in the freezer. We left one portion out. We cut it into smaller pieces, cut some potatoes, onions, garlic and carrots. Put them in a tray in a 550 degree oven for 10 minutes. The beef browned quite nicely. We then put the items in a pressure cook with some water and left them cooking for 1 ½ hours. We served them in on a thin base of very hot brown rice. I had two large servings. It was delicious.

It is a Saturday morning in the Twin Cities of Minneapolis and St. Paul. As we have been doing for a few months, my wife and I drove to the Costco store in Minneapolis, met with our son and went grocery shopping. Today we were not able to find Three Berry Blend bags. We got separate bags of strawberries and blueberries. Our son will stop later today at the Costco in Eagan. MN and will see if he is able to find a couple bags of mixed berries and a box of pens that we forgot while in Minneapolis.
This week I watched the Association for Computing Machinery (ACM) webinar “Lessons from COVID-19: Efficiency vs. Resilience” by Moshe Y. Vardi. It seems that the webinar is only accessible if you are an ACM member, which I am. I enjoyed the point he made of efficiency versus resilience not only at the software but also at the political level. At no point he mentioned politicians or political parties. In my opinion, it is a very good one-hour webinar worth your time. Continue reading “Backspace String Compare”
I was planning on working a couple blocks (a block entails 2 hours) on this post but ran out of time. The reason for it is that I will be collaborating with a group by posting some of their articles in my blog. It appears that the group uses Google Docs to create the text for their posts. For text I use Microsoft Word and for diagrams Microsoft Visio.
I have never before directly included a Google Docs on WordPress. That is the reason I had to learn the process, and check for possible caveats. That took some additional effort and time. If interested it seem that the section Use Google Docs to Post to WordPress on Resource Center provides the necessary steps.
Posting to WordPress from Google Docs is easy with the add-on for WordPress.com (Jetpack).
Before continuing, make sure you have a free Google/Gmail account,
that Jetpack is installed and configured on your WordPress site,
and that you have registered with a WordPress.com account through Jetpack.
Make sure you take into accounts the prerequisites paragraph in the section in question. I just made sure I complied. At this time I am using the FREE version of Jetpack for WordPress. I am considering a paid subscription but have not committed to it yet. Continue reading “Partition Labels in Java”
Yesterday I read a very interesting article “China is escalating its punishment diplomacy” by Jamil Anderlini in the Financial Times. If you did not get a chance to read it, please do so. You will be surprised how open China is manipulating politicians all over the world.
Another article of interest might be “China sharply expands mass labor program in Tibet” by Cate Cadell in Reuters. The Chinese communist government is picking up people in Tibet, teaching and deploying them to work in groups all over China. The article seems to validate the idea that the cost of manufacturing in China is going up and in order to continue to attract companies to manufacture in China, they need cheap labor. China uses a 72-hour work week which is getting expensive, and in order to continue to be the single provider of globalization, they need to get cheap labor. Continue reading “Divide Two Integers”
