As mentioned in a previous post, I will be spending some time learning, experimenting and working with the MongoDB NoSQL database.
MongoDB is a FOSS (Free of the Shelf Software) document-oriented database engine. It is one of the most popular engines in its classification. MongoDB Inc offers many free resources for developers to learn how to use their database. There are many books that offer from introduction to advanced information and examples on how to use this tool. I have been reading and experimenting with it for some years.

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”
Code complexity is a subject that is taught early on in Computer Science curricula. Not sure if early is the reason why many software developers tend to forget what it is and how to apply it.
Last week a group of developers were talking about the complexity of algorithms and Big O Notation came up. As a matter of fact when considering complexity there are:
|Big O notation

Most software developers now a day write code using object oriented (OO) programming languages. In some cases, due to performance reasons, some code may be written using a non OO language. One way or the other, the question may come up if return codes are better than using exceptions. I do not believe you can come with enough reasons to justify one method or the other which would be accepted by most software developers. What I will do is discuss some considerations and give my opinion. Please take it all with a grain of salt. Continue reading “Returned Value versus Exception Handling”
