Real benefits of SOLID principles

Those SOLID principles many talk about are really helpful. But why? Because they were stated and tested by advanced programmers in real situations? I say this is an enforcement, a reason to trust them, but not the reason to jump on them. It’s actually about understanding the benefits of using them and being able to identify when you need them.

All of them help in the way of having clean code. But why would you need clean code? You can really have messy code which does the same thing as the clean one. Except when you aim for long term healthy business. Solid code makes solid business.

Each of the SOLID principles comes with its ideology, but does not guarantee a 100% benefit, because there could be other factors which more or less collide with them, the first one being when you play around the principles, but do not apply them properly.

While the benefits you get from these principles are well known, I’d like to state some of them which for me are more real, more close to the business side. Continue reading Real benefits of SOLID principles

“Obsessing About Best Practices”

Today I read a very good article about some mistakes that one can do as a programmer, and the only idea that made me a little bit uncomfortable was the one about best practices. The author was talking about “Obsessing About Best Practices”. While I agree obsessing is not healthy, I consider his statement “There are no best practices.” is too strong. I think it’s something that one could hear and get too confident about their decisions.

Thinking the things you know today are the best there can be is wrong. Trying to apply everything you’re hyped about is wrong. Giving the same 2 or 3 methods you know as solutions to any problem is wrong. Not being curios to find out what else exists beyond any best practice and beyond your knowledge is fatal.

Still, there are some general best practices that you should at least think of before writing code. There are those SOLID principles that some have no idea about, some guide themselves through them, and for sure some are not very happy about. And many design patterns which were tested for years and years. Again, I agree about not being obsessed with them, but try to understand where they can come in need. And stay up to date. The Singleton was a rock star some years ago, now it smells like a dead body in many misused cases.

Because “There are no best practices.”, projects can take on a really, really unwanted highway. I say they do exist. Just open your mind to see which are the proper ones for your case.
