Yesterday I was looking at a problem on the HackerRank web site. The title is “Self Balancing Tree”. The challenge is to write the insert() function / method in such a way to insert new elements and keep the binary search tree balanced. As usual, no matter how familiar the subject might be, I always research the subject before planning a solution. By doing so I refresh my knowledge and in many cases learn one or more things. To research I try to use Google research and go for Wikipedia articles. Based on what I find I tend to go into different on-line articles or books. Continue reading “AVL Tree”
As I have mentioned on different blog entries, I always try to read books, watch videos, take courses and experiment with technologies that I will be using in a project. For example, I have been developing software using the C and C++ programming languages for a long time. That said, I have read a couple dozen books on the subjects. It amazes me that every time I learn something new or question a way I view some concept. In this case I am starting a project using the Spring Framework. The first version was written by Rod Johnson, who released the framework with the publication of his book Expert One-on-One J2EE Design and Development in October 2002. A lot has changed in the past 14 years including new enhancements and tools. Continue reading “Static versus Dynamic Polymorhism”
I tend to wake up early morning and spend some time reading on my phone. Today was not different. I browse my Tweeter account about three times a day. Typically I do not reply or re tweet. I am a firm believer that software engineering and understanding the inner works of computers and how operating systems run applications is extremely important in producing quality software.
The following is a tweet from David Mwathi (re tweeted by Marcus Biel):
“Good programmers are good because they make a diagram before they start coding”
As I have mentioned in a previous blog, it is very important to reduce as much as possible distractions (i.e., email, phone, texting) while at work and to dedicate a percentage (i.e., 10% to 15%) of your daily workday to learn something. On occasions I decide to learn a new technology (e.g., Spring). Sometimes I decide to spend time polishing on topics I know (e.g., Java) while sometimes I need to refresh concepts (e.g., Huffman Codes and Tries) that I learned in school but seldom use at work.

I have dedicated my professional career to different disciplines (i.e., graphics, software engineering) within Computer Science. In this blog entry I would like to summarize some observations regarding computer languages. At different stages in life (e.g., college, work, self study, and business owner) most developers are required or just decide to learn different programming languages. An issue that frequently comes up with project managers is: “Knowing and using multiple programming languages is better or worse for a software developer?” In this blog entry I would like to provide some insights on how to respond to this question.
