Yesterday I spent time attempting to port a C DLL that I wrote some time ago to generate MD5 digests for a storage server. At the time I used as a base code provided by RSA Data Security, Inc. and designed and implemented a set of functions that could be directly called in applications / servers that would require generating MD5 digests for strings and files. When done I package the results into a DLL. The library has been in production for a long time. I used the C programming language for performance and the code was built for 32-bit processors.

Please do not be shocked by the introductory sentences. I was born into an Italian family. My parents moved from Italy to Peru in the 1930’s. Growing up in Peru we were introduced to have wine with weekend meals. In particular wine was only served for lunch. My sisters and I started drinking lemonade with wine. After a few years we moved to have a desert that is made of fresh strawberries with sugar and wine. You just mix the ingredients and let them sit for a couple hours in the fridge. If you try it this summer, make sure it is served chilled. As we got older we had weekend lunch with a couple bottles of wine. None of us ever had issues with alcohol. Different cultures have different approaches to solve the same issue. We just need to make sure that what we do works to solve the problem. If it does not, learn and put practice different approaches. This philosophy can and should be applied to life and software development. Continue reading “Flatland Space Stations”
Yesterday on snail mail I received a pin from the Red Cross. Apparently I have given blood 16 times so far. That adds up to two gallons of blood. Planning on continue to donate in the foreseeable future.
As you can tell based on the code we will be using for this post, I am a fan of Ian Fleming’s spy novels staring James Bond. I read all his books when I was growing up. Have watched all the James Bond movies and own a DVD collection of all the titles that have been released of 007.
It is Thursday April 11 and this area of the Twin Cities of Minneapolis and St. Paul has received since yesterday around noon to today around 04:00 PM about 10 inches of snow. Around noon today the snow stopped and we start receiving freezing rain. Schools are closed and there is very little traffic in the area.
According to the forecast, tomorrow will be raining during the day. Not sure if the precipitation will turn into freezing rain. One way or the other, staying home working is not a bad idea. Continue reading “ACM ICPC Team”
We all have seen and used annotations in Java. To be honest I have never before created my own annotation. From now on, when the opportunity arises, I will make sure to start adding my own annotations. To read more about the subject at hand, take a look at this page in Wikipedia.
This morning after waking up I read Why I Write a Data Science Blog by Rebecca Vickery. The subject of the post is to summarize the benefits that writing a blog, in her case regarding Data Science, provides her with benefits that help her improve towards her goals, and helps others starting a Data Science career with topics and situations that they might / will encounter at work.
I agree with her comments but would like to add that the idea of explaining some topic on writing is a great technique and applies to any type of subject. You do not know what you cannot explain. It is a simple as that. That is the reason I spend a couple hours every day reading, experimenting and then writing about what I have learned. I have tried to apply several of Richard Feynman techniques to my daily life. Hope they are working :o) Continue reading “Java Visitor Pattern”
I was going to say “What a week” but today is Sunday and in some calendars, the week starts today so technically last week is over.
Last Monday and Tuesday I had to deal with a water leakage issue generated by a new water meter installed by the city a couple weeks ago.
On Wednesday, our SUV popped the two right side tires in a set of potholes covered with water as I was entering Cedar Avenue also known as 77, on my way home from having an oil service at the dealership. Continue reading “Climbing the Leaderboard”
UPDATED I mentioned in a previous post that I experienced some water problems in my home office after the water meter was replaced at home. The contractor who did the update stopped by yesterday afternoon with a powerful fan to help the small amount of water that had leaked into my office dry up. This morning the humidity from the carpet was gone. He also mentioned that they will replace the four books that got damaged by water. I will call this afternoon to return the fan and inform them of the four books.
I randomly selected the Prime Checker challenge at HackerRank. Read the requirements and spent time working on a solution. When I was ready to give it a try, noticed that it would not allow me to enter my solution. In addition, it seems that the scaffolding code has an issue and a message indicates that you need to address it. Not sure what is going on. I had to skip it because I am not able to enter my code. Continue reading “Prime Checker”
Woke up around 04:10 AM and decided to go back to sleep. Later I got up at 05:00 AM. Seems like another cold morning in the Twin Cities of Minneapolis and St. Paul. The skies were clear and it seems we have a full moon.
Yesterday I worked on the Highest Value Palindrome challenge at HackerRank. I was able to complete it but did not have time to generate a post. Hopefully it will be done in an hour or so. Continue reading “Highest Value Palindrome”
