It seems that most résumés have a generic objective copied from one of many "how to write a résumé" articles. You know the kind; "To utilize and expand my skills in blah blah blah". I think that's lame. Why start your résumé with some vague cookie-cutter bullshit that you copy-and-paste then forget about? My objective is "To work on a project that users want to use and maintainers want to maintain.". It's nothing fancy but it's honest and to the point and I actually believe it. I'm glad when something I create is useful to others and they want to use it. I'm glad when someone, usually myself or a coworker, is able to extend or change it to do something else.
But not everyone wants those things. Recent experiences with clients who are more concerned with making sure the software looks like it works rather than actually works reminded me that working software is the primary measure of progress. Because of that, I updated my objective to say "To create working software that users want to use and maintainers want to maintain." Even more true and even more to the point. And that's something I care about.
What's your resume objective? Do you actually believe it and try to live up to it?

Easier object setup in ActionScript
I recently thought of something that will make it easier when I'm creating instances with different values in ActionScript and thought I'd share it. It's sort of a mix of default parameter values and optional parameters and it makes it much more convenient to setup instances of things that are slightly different.
Let's suppose I have a Weapon class with some basic stats:
And assume I have some other code that creates a bunch of instances. They're mostly the same but ideally I could just specify what's different than the default. Something like this:
Just use it in the constructor or some section external to the object like a Factory.
I'm sure I'm not the first to do something like this but I think it's a more convenient way to create things. If I ever find myself working on a 7 day long project and need a quick way to add content, this could be useful....
Let's suppose I have a Weapon class with some basic stats:
class Weapon { public var name:String; public var attack:int = 10; public var defense:int = 10; public var speed:Number = 1.0; public var heavy:Boolean = false; public var tags:Array = ["weapon"]; /* skipping constructor and a "describe" function that prints the values */ }
And assume I have some other code that creates a bunch of instances. They're mostly the same but ideally I could just specify what's different than the default. Something like this:
var weapons:Array = [ new Weapon("stick"), new Weapon("sword", { attack: +2, defense: +2 } ), new Weapon("club", { speed: -0.25, heavy: true } ), new Weapon("knife", { attack: -2, tags: ["sharp"] } ) ]; for each (var weapon:Weapon in weapons) trace(weapon.describe());
It would be really cool if I could get something like this as the output:
stick = { attack=10, defense=10, speed=1, heavy=false, tags=weapon} sword = { attack=12, defense=12, speed=1, heavy=false, tags=weapon} club = { attack=10, defense=10, speed=0.75, heavy=true, tags=weapon} knife = { attack=8, defense=10, speed=1, heavy=false, tags=weapon,sharp}
Well, wish no more because it's possible. Here's the function that makes it happen. It takes two things and expands the first by the second. It could be improved to handle other types, but this is enough to get started with.
public function expand(receiver:Object, expansions:Object):Object { if (receiver == null || expansions == null) return receiver; for (var property:String in expansions) { if (receiver[property] == null) continue; var value:Object = expansions[property]; if (value is Number || value is int) { receiver[property] += value; } else if (value is Array) { for each (var element:Object in value) receiver[property].push(element); } else { receiver[property] = value; } } return receiver; }
Just use it in the constructor or some section external to the object like a Factory.
public function Weapon(name:String, values:Object = null) { this.name = name; Util.expand(this, values); }
I'm sure I'm not the first to do something like this but I think it's a more convenient way to create things. If I ever find myself working on a 7 day long project and need a quick way to add content, this could be useful....
