I'm a big fan of comics, and I'm also a big fan of software development. Coincidentally, I see metaphors and analogies for software development just about everywhere I look.
Comic books have come a long way from the days when it was just about the guy wearing the mask or the brightly colored costume who rushed in to save the day. In the early days, the stories were pretty straightforward: the bad guys were always easily identified, and so were the good guys. But stories these days have become more complex, more adult, and they tackle tough issues. But one common element persists: the heroes and villains tend to wear costumes or masks that exemplify their heroic or villainous persona.
The attire of a hero or villain isn't simply done for theatrical reasons (although there is certainly a large and undeniable element of theatricaility to it). The mask grants the wearer anonymity; those who behold the wearer have no idea who the wearer is, and with that anonymity the wearer is emboldened to do things he or she might never do or have the courage to do if people knew who he or she was.
Anonymity grants the wielder power. What separates the heroes from the villains is a sense of responsibility and what they choose to do with it. A villain might have a sense of responsibility but choose to ignore it, and use his power for personal gain.
When a civilian in a comic book views a mask-clad individual for the first time, they don't really know whether that individual is a hero or a villain, or just some bloke in a costume. They might be able to infer some things from the costume, but they have to trust their instincts. A great failing of classic villains seemed to be that they went out of their way to look villainous; they were so easily identified that they were easy to avoid or locate and defeat.
But the greatest villains actually looked like one of the good guys, or just a regular Joe. They managed to garner the trust of those around them, and then used that trust against those who placed it in them. You see, sometimes, wearing no costume at all is a mask in and of itself.
So now we come to the part where we apply this to software.
All software wears a mask. It's called the user interface. It doesn't matter if it's a desktop application, a Web application, a framework, a Web service, a device driver, or anything else. The mask is the face that your software presents to the public, how the public perceives the software when they first look at it.
Most software presents itself as the next silver bullet to any given problem domain. After all, what software doesn't want to be perceived as a Hero? A user, looking at your software for the first time, is forced to place a certain amount of trust in it because all they can see is its mask. And the mask grants the software anonymity and power.
Unless you're giving the user the source code, and the user knows how to read it, and can build it themelves, they're at your mercy. They're trusting you to be heroic on their machine: to have a sense of responsibility, and to use the power you've been granted wisely.
Sadly, much precompiled software relies on its anonymity to conceal its true state: that it is miserable, ugly, unmaintainable, untestable, bloated, unreliable, and unsafe. Software of this nature is hardly heroic; rather, it's villainous. It might handle user data with reckless disregard for integrity, security, or consistency. It might crash frequently, and for no apparent reason. It might install spyware or adware. It might log keystrokes. It might be riddled with bugs, be poorly documented, and have no consistent coding model or standard. It might use an inconsistent user interface paradigm, or hog system resources. It might break other software. It might do all of these things.
The question we are compelled to ask is this: What is hiding behind the mask of the software that we're writing, right now, at this moment? Is it heroic? Or is it villainous? Despite claims by certain advertisers, it isn't really enough that "it just works." It has to work well, and responsibly.
Some of the greatest heroes in comic book lore were brave enough to take their masks off so that people could see them and know who they were. Would you be willing to open your code base up to let the world see what you're doing? Would you feel comfortable letting everyone see the code that you write and what it's doing? Would you be confident or proud of your work? Or would you feel shame? Embarrassment? Even guilt?
Not all software can be heroic. There are always mitigating circumstances. But we can all strive to be heroic. It's when we strive to be villainous that we need to be worried. Or when we're writing villainous software, and we know it, and we choose not to do anything about it. We all have a choice. We can choose to make great software that behaves responsibly, and does what it says its going to do, or we can abuse the trust placed in us and serve ourselves.
Take stock of the software you're writing. Find out what's behind its mask. If it's not software you'd be prepared to unmask in front of its users (aside from intellectual property issues), chances are, something somewhere has gone horribly awry. What are you going to do about it?
