“From a higher level of existence all of this is just an organic process that has both good and bas aspects to it. It has purpose and is leading us somewhere.”

Good Tools

I have this image of a metal-worker who has just finished manufacturing a fine tuned machine part. I see him running his fingers over it’s surface to feel it. This affectionate gesture is a key ingredient in quality assurance.

This came to me as I am working on some code (PHP server with a Flex/AS3 client).  I encountered  some poorly implemented components and the quality thing to do was to improve them (this is sometimes referred to as re-factoring). I have decided not to do that and it’s bothering me, but I am sticking with my choice.

Working with code means there is nothing tangible to run my fingers over. Actually “running my fingers over a component” in programming is called unit-testing – it is achieved by “activating” the component independently and checking that it behaves properly. Debugging tools are required to do this – they provide a means to activate, control and inspect the component. The environments & tools I am working with (all open-source) are missing functional debugging capabilities and tools.

I am not running my fingers over my components because I don’t have the tools to do it.  Because I don’t have tools to run my fingers over my components I make lower quality components, which sometimes don’t function as expected, which force me to fix and change my components. Because I have a lot of fixing and changing to do, a lot of the time I spend coding I am in a “failed” state of mind. Because I am in a “failed” state of mind I am not passionate about what I do. Because I am not passionate about what I do I create mediocre components – which require quite a bit of “running fingers over”… and on and on…

Why is this bothering me? I like to like what I do. I like quality, I have great faith in quality.

Why did I choose to stick with what I have? There is a bigger picture in front of me. The code is part of a larger project. The quality of the project can tolerate the existing code. Quality needs context – I can continue to pursue the highest quality code, but that would be at the cost of a higher quality process. If & when it will become relevant, the project will create a context for me to go back and to improve the code.

My take on this:

  • Get good tools
  • Appreciate the tools I do have
  • Aim for uncompromising quality
  • Compromise quality when it’s relevant
  • Have a bigger picture so I know what is relevant and what is not
  • Get good tools
