Obviously there are syntactical differences between YAGNI and KISS but I can't see any semantic differences between them. Are they really in essence just the same thing?

One of the most frequent arguments I hear for not adhering to the SOLID principles in object-oriented design is YAGNI (although the arguer often doesn't call it that): "It is OK that I put ...

The Pragmatic Programmer is highly recommended by many people. I've just finished reading it, and I can see why people recommend it, although I would point out that Code Complete covers almost all ...

I can grasp the part "do one thing" via encapsulation, Dependency Injection, Principle of Least Knowledge, and You Ain't Gonna Need It; but how do I understand the second part "do it well?" An exa...

For my software development programming class we were supposed to make a "Feed Manager" type program for RSS feeds. Here is how I handled the implementation of FeedItems. Nice and simple: struct ...

The YAGNI "principle" states that you shouldn't focus on providing functionality before you needed as "you ain't gonna need it" anyway. I usually tend to use common sense above any rule, no ...

G'day, While having a think about this question here about overdesigning for possible future changes it got me thinking. What reasons against can you provide to people who insist on blowing...

When I write code I only write the functions I need as I need them. Does this approach also apply to writing tests? Should I write a test in advance for every use-case I can think of just to pla...

As I've increasingly absorbed Agile thinking into the way I work, yagni ("you aren't going to need it") seems to become more and more important. It seems to me to be one of the most effective...

Do they contradict? Decoupling is something great and quite hard to achieve. However in most of the applications we don't really need it, so I can design highly coupled applications and it almost ...

In code, it's generally pretty easy to add new classes to provide additional functionality and such. I have a fairly good understanding of refactoring code and what's involved so YAGNI generally ma...

Should you always create an interface if there's a possibility that there might be something else that could use it, or wait until there's an actual need for it then refactor to use an interface? ...
