  • A Modular Approach to Web Development

    MVC is about loose-coupling, and Modular Programming takes that concept to the extreme.

In this article you will presented with a different…

  • Foundations of Programming: Building Better Software

    Karl Seguin has released the official, and completely free, Foundations of Programming eBook. Although simplistic, every programming decision I make is largely based on maintainability.

  • Agile Database Deployment Using Phing

    Phing allows you to use SQL to define changes to your database schema, making it possible to use a version control system to keep things synchronized with the actual code. A common way to automate development and deployment tasks is by writing shell scripts, however, Phing provides some advantages over shell scripts for task automation.…

  • The best code is very shy

    The best code is very shy. Like a four-year old hiding behind a mother’s skirt, code should not reveal too much of itself and should not be too nosy into others affairs. But you might find that your shy code grows up too fast, shedding its demure shyness in favor of wild promiscuity. When code…

  • Web Applications: Spaghetti Code for the 21st Century

    The software industry is currently in the middle of a paradigm shift. Applications are increasingly written for the Web rather than for any specific type of an operating system, computer or device. Unfortunately, the technologies used for Web application development today violate well-known software engineering principles. Furthermore, they have reintroduced problems that had already been…

  • Getters and setters create unnecessary coupling

    Every getter and setter in your code represents a failure to encapsulate and creates unnecessary coupling. A profusion of getters and setters (also referred to as accessors, accessor methods, and properties) is a sign of a poorly designed set of classes. “Getters and setters should be avoided because they break the encapsulation OOP offers”, says…

  • Analysis of coupling within the Zend Framework

    Neil Grab wrote: One of the Zend Framework’s strongest drawing cards, as I see it, is its loosely-coupled structure. The name Zend Framework may be a misnomer, in fact, as ZF is more a set of reusable libraries than an actual application framework. I won’t go into detail about the advantages of loose coupling, but…

  • Design Patterns Quick Reference

    Jason McDonald posted some quick reference diagrams for the Gang of Four design patterns on his blog. Each section has the name of the pattern, a quick description, and the class diagram for the pattern. Definitely a handy thing to have around. Design Patterns Quick Reference (PDF)

  • The World’s Most Misunderstood Programming Language

    …has become the world’s most popular programming language. This is the story of JavaScript Most languages die in obscurity. Only a few are able to build a following beyond a single project or company. And only a very small number of languages become important.

  • 13 reasons why UML failed

    One of the reasons is that UML attempts to become a programming language. By aiming to be able to generate full code actually UML tries to be a programming language. In my mind there is a big problem with a general purpose graphical programming language. In human history the written form of all languages evolved…

  • Scrum and XP work well together

    A programmer cannot be Agile if the person that manages him is not Agile as well, and vice versa. That’s why Scrum focuses on management and organization practices while XP focuses mostly on actual programming practices, and that’s why they work so well together. This excellent free book aims to give you a head start…

  • A Painless Remote Projects Synchronization Utility

    So, there you are, asking yourself – “How the hell am I going to deploy my next application across multiple servers?”. First, you write some shell scripts. One that checks out the project from the repository and the other one that runs all the tests. Then, you master the synchronization technique and realise that combined…

  • Software Engineering for Web Applications

    A twelve-year-old can build a nice Web application using the tools that came standard with any Linux or Windows machine.
