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 looking at several articles on binary trees and thought it would be a good opportunity to write some Java code in order to refresh knowledge of binary trees, in particular with BSTs (Binary Search Trees). You never know what new things are out there.
I am not sure if most system architects and software developers run into the same situation as I do. I have learned and worked with many data structures and programming languages. I do not work with every single data structure often enough that I recall how to implement or use it as far as all the associated methods and functions. I have a reasonable understanding of most data structures and I can get back on the horse rather quickly. Continue reading “Distance Between Nodes in a BST”
Earlier this week I ran into a description of Radix Sort. This sorting algorithm has been around for a few centuries (yes; that is not a typo). The algorithm dates back to 1887 to the work of Herman Hollerith (and yes; he was the inventor of the Hollerith Card Code for punched cards used in the past century).
This sorting algorithm is not the fastest, it requires additional space, but has been around for a long time. When you read about it, seems like it should not work; but it does. Continue reading “Radix Sort”
