The Decorator pattern, or its cousin, in JavaScript

piccoloprincipe — Thu, 09 Feb 2012 09:35:14 +0000

The Decorator pattern is a way to reduce multiple levels of inheritance that clash with each other; for example, if you want to create objects which address one or more between the X, Y or Z responsibilities, plain inheritance leads you to create the following classes:BaseClass X Y Z XY XZ YZ XYZwhile the Decorator pattern allows you to create just: Preview Text: ...

Databases have long been the poor cousin of the application tier when it comes to many of the processes we take for granted in the .NET world. Source control management, for example, is near ubiquitous for application files and there are several excellent VCS products which make versioning a breeze.

Practical PHP Refactoring: Convert Procedural Design to Objects

piccoloprincipe — Wed, 08 Feb 2012 09:30:46 +0000

Even in languages where there are no constructs but classes, there is no constraint that can force a programmer into writing object-oriented code. In many cases, just wrapping a series of functions into classes do not result in the design.The Convert Procedural Design to Objects has great benefits, but it reaches a very large scale (potentially the whole application).What does object-oriented...

Who's Responsible for This? Strategies Ops Teams

anichols — Wed, 08 Feb 2012 05:00:45 +0000

I’ve been having some discussions about this lately so figured I would write something about the topic. Being a member of an Ops team can be pretty challenging at times. The job can be high pressure and often it feels like you spend all your time fighting fires, shaving yaks, etc. One of the difficult parts of being in Ops is that it’s often hard to put your mark on things, to use your...

Teach Teams to Win AND Fail

sciske — Tue, 07 Feb 2012 15:11:50 +0000

I’m going to tell you a story about how I almost failed as a manager. I say almost because it was only because of Bob Smith that I recovered and really understood the error of my ways. Bob is a factious character because the innocent should be protected. However, the situation is real and the lesson is a good one that I would like to pass on. One of my first experiences...

Make your process your Rock Star, not individuals

anichols — Mon, 06 Feb 2012 12:51:28 +0000

I recall a few jobs ago I was managing the Systems Engineering team and trying to grow it into a group that could handle the daily onslaught of issues that would plague our service. We had recruiters working on sourcing folks & we felt like we had very high standards for who we wanted to hire. We talked to and turned away probably hundreds of folks it felt like (I got really good at...

Practical PHP Refactoring: Tease Apart Inheritance

piccoloprincipe — Mon, 06 Feb 2012 09:33:14 +0000

We are entering into the final part of this series, on large scale refactorings: this kind of operations is less predictable and less immediate. However, it is important to be able to perform them with small steps whenever necessary, if we don't want to get stuck in a situation with dozens of broken classes and no clear further step to take.

DZone's Different!

austinrk — Fri, 03 Feb 2012 18:00:36 +0000

Hello DZoners!My name is Austin Kowitz and I’m a graphic designer at DZone. And you can mostly blame (praise?) me and DZone developer, Ross Jernigan, for what you see currently at DZone. We still have tons of ideas we haven't implemented yet -- but we're doing the agile thing, releasing early, releasing often. So we'd love hear your feedback, whatever it may be.

Agile with a Little Bit of Lean

sciske — Thu, 02 Feb 2012 15:04:13 +0000

I’m probably one of the biggest fans of Agile. Not because it’s one of the hottest things going on right now in the development community. I’m big on Agile because I’ve seen what it can do for teams and organizations first hand. Transformational would be an understatement. Unfortunately there are plenty of shops out there not realizing the benefits that agile can bring. ...

Practical PHP Refactoring: Replace Delegation with Inheritance

piccoloprincipe — Wed, 01 Feb 2012 13:37:32 +0000

Delegation is a more flexible solution with respect to inheritance, because it allows to change collaborators by introducing new classes. However, it hides the public protocol of the collaborator into a private field.If you find yourself writing many delegation methods, you may refactor to inheritance to simplify the code. The subclass will inherit everything automatically, which makes...
