I have no authority in the industry. I am the one guy who spends minutes, if not hours, pondering on a problem. I over-analyse, and my lack of experience only makes the analysis take longer. I think more about the underlying solution than I do about the next line of code. I think more about the existing code, than I do about the next script. You might have guessed, I have just recently left academia. If there are any experienced developers out there who have seen these patterns, please share your perspective. I offer no solutions because I think the patterns speak for themselves.
Each functional test fails. If it does not, something will break in production. We spend most of our time trying to understand the gotchas. We have no idea how many points of vulnerabilities are contained in the system. So each time we try to finish the current problem, without worrying about the next. We fail to see that our program is brittle. As a result we do nothing about it.
To us, new requirements necessitate new code. We do not think that maybe the program already does that, or it could do that with just a few tweaks, maybe even deleting some useless, though non-duplicated code, because the scenario is handled elsewhere. Instead, we introduce new classes and functions, sometimes even modules. We fail to realise that the new specifications actually change our problem, and that changes what our code is trying to accomplish. So maybe the previous data structures need to be rethought, and the previous design revisited.
Business thinks we’re doing more work when story cards are moving to the right on the story wall. The progress we’re making is visible. The features that we’re completing can be showcased. Life is great! However, we may be doing more harm to the program than we’re helping to solve. Each rushed decision is a dimension to introduce new problems. Implementations that are not well-thought out will need to be changed very soon as we understand our problem better. If they are not changed, and this is the worst case, they drive the project into the abyss of never-ending destruction.
Our program is working. Tests have been written and they are passing. Do not allow for this part of the software to interfere with the other part. We do not want to spend days debugging. The code we have written has become a monster. And this monster has been fossilised. We end up with a large program, for a small problem.
Writing code is a tedious process. Remembering how to implement lambdas or configure the postgres database is hard work. Having all the tools you’ll need to do a particular feature is not always feasible, so you need to do research. You read many blog posts, trying to understand them until you stumble on the one that solves a problem similar to yours. Sometimes you need a completely fresh implementation, taking out of your toolbox of programming knowledge. Most of us do not step back and reflect when we get to this point. Instead we try out different solutions until we land on one that barely solves the problem. And then we move on to the next feature.
So my work description says I am a programmer, and as long as I’m writing programs, I’m doing my job. We do not think as developers of a product or tool much bigger than signing off on a project, tools that other people may have to improve in the future or rely on to build other tools and products. As long as the program works, we do not worry about the quality of the software. We do not think, what if NONE of the tools or languages currently in popular use can best represent our solution. Instead, we dive in and start building.
It would be hard to avoid all of these pitfalls all the time. At some points we will quell some fires, throw more code at a program without investigating a system’s current capabilities, chase deadlines, avoid introducing errors, go for less than optimal solutions because we’ve already spent too much time, and well, be programmers. However, we ought to be aware of these practices and not do them every single day. If and when you see these practices and given that you can, run!
