The Clean Coder, Chapter 1 and 2 (Week 1)

I read the the introduction, chapter 1 and chapter 2 of the The Clean Coder by Robert C. Martin. I found the introduction funny because the author basically quit the job he did not like while he was making $7,200 a year and and a few months later got the same job back for $6,800 ! I guess the lesson to learn here is the importance of wisdom.

The second and third chapters were about professionalism and when to say no to something (how to be a professional). Being a professional means that you care about the product you build and take responsibility for any problems that may arise. The author explains that to be a professional you must not create bugs in your software and if you make an error, you must apologize. Never release any code that you know to be faulty. And the software you write must be flexible.

The author also talks about the importance of learning. It our responsibility as professionals to make sure we are marketable. We have constantly to learn and strive to improve ourselves.

I found the second chapter interesting. The author explains why it is important to say no to a request by your boss and why not to use the word try. I think following this idea is hard in practice. What if you boss insist you complete something within a certain time limit (which is not possible)? It is very easy to just comply, but it is hard to say no given the fact that your boss has the authority to fire you. But I guess being a professional is not easy, you have to put the software that you produce over everything else.

Clean Code – Chapter 1 and 2 (Week 1)

I read the first 2 chapters of this book almost 16 months ago and I did not quite understand the significance of clean code back then. This week I decided to listen to the video version of clean code (available in SafariBooksOnline). The video version made it much easier to understand and I had a few good laughs.

In the first chapter Uncle Bob explains why clean code is important. He tells us the story of Sword Inc, a software company that failed because they produced bad code. When code is not clean the productivity of the development team decreases as time increases. The reason for this loss of productivity is that the developers build a mess as they develop the product. And the software product eventually fails becuase when the management demands new features within a certain deadline, the development team is not able to deliver because they just can’t.

The management tries all sorts of things (like increasing developers) to improve productivity, but nothing works. According to Brook’s law, adding more man power to a late project makes it later.

Finally the management turns to the developers for a solution. The developers solution is to redisgn the entire system! Management does not want to do this since it is expensive. The mangement however, after some time, decides to do it. But even this would not solve the problem. Eventually the company would loose customers because when they replace the new product for the old (more feature rich) product, customers leave for better products.

The only way to solve this problem is to stop running away from it and clean the mess.

So what is bad code? You know that a software systems contains bad code if it is rigid, is fragile, lacks seperability and is opaque. Uncle Bob goes on to explain that bad code is the fault of developers not management, not anybody else.

The second chapter is all about making your code more readable with the help of better naming strategies.

I can relate to this chapter and the Sword Inc company failure. Last semester I wrote software for a class project. Since we only had a limited amount of time and a bunch of requirements to fulfill, I rushed through the development process. As a result of my rushing, the code lacks the properties of clean code. If I had to use the code again or implement a new requirement, I would be lost.
