Good morning! Hope your day has started on the right note. Yesterday was quite hectic for me. Hopefully the day will go as smooth as possible. Continue reading “Merge Sort Revisited”
Good morning software developers and software engineers! Hope your day has started on the right note. Every morning, weather allowing for it, my wife and I have breakfast and go for a brisk walk. Today was no exception. Before 08:00 AM I have watered plants in the yard including a rosemary bush that we planted a week ago or so, showered, shaved, got dressed and started my work day. It is amazing how well you feed during the day once you have exercised, no matter how short or long.
Last week I read the article (let me see if I can find it in my Twitter account @john_canessa … found it) Cybersecurity bills gain new urgency after rash of attacks. It seems that both political parties, Democrats and Republicans are pushing a bill that will help our country against cyber attacks. In the past few months we have seen hundreds if not thousands of attacks, some to disable our government, companies and organizations or to ask for ransom. One of the proposed ideas is to force targets to disclose in a short period of time (24 hours or so) any cyber breach they have experienced. This will allow the government and other organizations to take action as needed to prevent the same type of attacks. In my opinion there should be some type of penalty for the bad actors in an attempt to curb their proliferation (transparency and accountability). Will see what happens with the bill and its implementation! Continue reading “Flatten a Multilevel Doubly Linked List”
Good day and hopefully you had a nice long weekend.
It seems that COVID-19 vaccines have been inoculated to about two million people in the USA. Apparently the vaccine is being well received by recipients. The issue at this point seems to be able to determine the efficacy against different virus mutations and how long our bodies will maintain resistance to it. In my humble opinion these two factors will take time to determine and must be backed up the actual (non edited) and unbiased data.
My sister sent me a link to the article “History isn’t just for patriots” by Daniel Immerwahr published by The Washington Post. I enjoy reading (mostly computer science related books, papers and articles) but also enjoy reading different subjects in order to understand the world which is inhabited by humans. In general we are extremely complex and hard to understand.
Reading the article I detected a taste of political bias. If you are interested I encourage you to read the article and form your own opinion.
At some point the author makes a comparison between history and geometry, in specific to the Pythagorean Theorem. I asked my wife when was the last time she recalls using it, if any, and for what purpose. She had no recollection of ever using it outside the geometry class while attending middle school. On the other hand, I use it often due that I design and develop software and have interest in algorithms and data structures among other computer science subjects.
On the other hand, we both have read several history books from different countries and at different times. To me unbiased history, which is very hard to find, provides facts that we can process and formulate an idea of what had happened in a certain part of the world during a specific period in time. With that information I hope to be able to better understand opinions from others. It is a fact that the winners write history.
Now a day we have a different type of influence. It comes in different forms and sources. For example I read the article in question that was published by The Washington Post and was sent to me by my sister who currently is living and teaching in China. After understanding the sources I need to read the article in an unbiased manner attempting to understand the set of points the author is providing and to understand the logic behind them. I have made my opinion and hopefully if you have a chance to read the article, you will also be able to generate your own educated opinion. Continue reading “Design HashMap – Third approach”
Yesterday afternoon the technician for a company that cleans ducts showed up for our appointment. Our dryer was having issues with the exhaust duct. We had to clean the dryer filter and restart the unit over a dozen times per load.
The technician arrived half hour earlier. I showed him the location for the exhaust and the dryer. He brought in some type of industrial vacuum and some hoses. I believe he used a camera to watch the operation while vacuuming the duct. Continue reading “Recursive Digit Sum”
Before we start I would like to thanks all of you that have subscribed to my blog. We have reached 2,000 subscribers!!! As a matter of fact, we currently have 2,150 subscribers. Thanks a lot!!!
It is so hard to find real news not politically opinionated. For example, I ran into an article that discussed the AztraZeneca vaccine trial in the UK. Apparently there have been two cases in which people that received the vaccine got severely ill. In both cases the trial stopped until further investigation. In both cases it was determined that the issue was not associated with the vaccine. The trials continued in the UK. Continue reading “Concurrent Skip List Map”
