Separating the concerns Separation of concerns is one of the key foundations to make software scalable, maintainable and readable. So even though everybody agrees it’s a “good thing”(tm), lots of object oriented code that is written does not follow this principle. How is it that this separation sounds easy in theory but is very hard [...]

Puppet for dummies Puppet is a configuration management tool which allows easy deployment and configuration ranging from one to a thousand servers (and even more).

(Re)discovering the SPL The Standard PHP Library (SPL) might be one of the most powerful, yet the most unused part of PHP. The lack of documentation about SPL makes it that a lot users don’t really harvest the power that SPL brings. During this presentation I will dive into the numerous iterators, data-structures and interfaces [...]

SPL De SPL, oftwel de Standard PHP Library. De meeste PHP programmeurs zullen er waarschijnlijk wel van gehoord hebben, maar weinigen zullen er mee gewerkt hebben. Deze library maakt het mogelijk om niet alleen sneller, maar ook efficientere en betere PHP code te schrijven. Niet voor niets gebruiken veel frameworks deze componenten. Tijdens deze workshop [...]
