Yes, prime numbers are a go-to challenge for me that I’ve been casually playing with since my earliest programming days. I’m not alone; prime numbers are important and popular enough that there’s an entire distributed computing project dedicated to finding the highest Mersenne Prime number (primes such as 31 and 127 that are one less […]
I recently started studying the Python programming language. I’m getting ready for a new programming-related position next year and one of my colleagues suggested using Python as part of it. I’ve heard of Python more and more over the past several years and I figured now would be as good a time as any to […]

One of CiviCRM’s strengths is the ability to add custom fields to hold specific information about your contacts. One thing it doesn’t offer (yet) is a calculated field type that will present the results of calculations of other fields. While calculated fields are generally discouraged in relational database design, they are sometimes necessary within a […]

(Updated June 9, 2016) The Challenge One of my current projects involves migrating a large amount of data away from an old custom Borland Paradox application into a new CiviCRM system. As with too many quickly-constructed apps, this old Paradox database wasn’t especially well designed and, among other the other challenges in salvaging the data, there were […]

In my last post on coding basics, I talked about turning an algorithm into code and used Euclid’s Algorithm as an example of programming a sequence of steps. There’s an even simpler type of algorithm that I want to look at this time. A formula, such as the one for converting Fahrenheit to Celsius, is also […]

In previous articles, I’ve talked about the importance of finding the right algorithm, or series of steps to follow, when coding a solution. Efficiency in terms of the amount of memory used and the amount of time taken by the operation are key factors for the program. Sometimes an appropriate algorithm is already available and in […]

The Switchboard Manager in Microsoft Access makes it easy to create a system of menus that will enable your users to navigate through your application. It also relieves you of the need to manage multiple menu forms and macro calls. Sometimes, however, you might want to keep all but a few users out of specific […]

As part of my latest project, I decided to try out WampServer, the Windows development environment for developing web applications with Apache web server, MySQL database and PHP scripting (Windows, Apache, MySQL, PHP – WAMP). Packages like WampServer and EasyPHP are simplified ways to create a testing environment on your PC without spending a lot […]

When writing programs, it’s often necessary to perform repeating operations on collections of items such as customer orders or invoices. Often, you can just iterate through the collection or count the items to determine how many times to perform the operation. When working with a hierarchy of items such as a directory structure where you have […]

(This article was updated in August 2018 for use with Visual Studio 2017.) Moving Beyond Microsoft Access I’ve written a lot about Microsoft Access over the years and still believe it’s a great training ground for people who want to learn to design database applications. Its user-friendly interface provides an easy learning curve and introduction […]
