What is good code?
-
If the code works as designed, it's good.

I go the other way, I know when code is crappy. Mind you crappy code tends to appear whenever I look at old applications, the more you learn the better your code should be. If it does the job and I like the way it does the job then AFAIAC it is good code.

Exactly. Right now, someone says their code is good. 2 years later, it's crappy. You learn and you get better.

Who determines if your code is good? What is good code and what are the precise criteria for giving it a status of "good"? Since most of your code will never be reviewed by your peers (outside of work) then how do you know it is worth a damn, really? If I think your code sucks but the next guy thinks it is good, then who is right? This kind of goes in line with my other thoughts about the "greatness" of an individual programmer. Who determines that a person is a great programmer and that person writes some damn good code? You? Me? None of the above? We obviously cannot make this determination about ourselves or our code. So who does?

Good code is modular enough, but not too much, such that when change requests come it is usually not a major rewrite.

I think I'll have to modify this one to: Assuming that compilers, interpreters and hardware works as expected, have you ever seen code that doesn't work as designed? ( Think about what code really is ... )

First, I do. After 30 years in this business, I know when I've done a good job and when I haven't. Second, I work with a team of other developers on our product. They aren't shy when they find a bug in my stuff. Third, we have a test group. One of them is actually 'embedded' in our department full-time. 'Marcia the Test Terrier' is relentless. Fourth, field service. Our service guys are also not shy about bugs. They also have direct access to our two bug reporting systems (one is for development issues, the other for customer issues). Finally, customers. They've spent from $1.5M to $5M on our product. They have certain... expectations.

Good code satisfies the customers' needs without undue cost. For the developers on my team, it means they don't have to jump through hoops to interface to my part of the product. For testers, they can perform meaningful, repeatable tests and easily report successes and failures. The service guys want the software to help them diagnose hardware problems (our product is a large printing press) and not get in their way. The customer wants the software to print, and wants to be able to have a lightly-trained monkey able to operate the machine. You can see that these 'customers' all have different needs, some of which conflict with each other.

See my answer to your first question. There are lots of people to tell me when my code sucks. Relatively little positive feedback comes back. Occasionally Marcia the Test Terrier tells me she likes a new feature. The service guys will also come across with an 'about time you guys did this'. I only talk to customers directly on rare occasions, so I don't hear much from them. Objectively my code is somewhat old-fashioned. While I do tend to implement 'patterns' as defined by the Gang of Four, I'm not as formal about it. I've written code that used those patterns when the book authors were in diapers. Some of my code exhibits anti-pattern or 'code smells' that are presently deprecated. For example, I use underscores in names occasionally. It still works.
This so spot on. Good code is in part measured by how it is used. I don't often bookmark posts, but I did yours. It needs to be re-iterated every time someone asks again about code quality and how to determine it. :)

Code is a design specification that can be translated into a program by a compiler or interpreted by a program - it's not a program.

Could you elaborate on which developers that should be? I mean, if part of the requirements is performance, then you can't make that true in general (some other developers will understand it, but not many). And code that doesn't meet the requirements is bad by definition..

To me, between the design specification and the actual source code there is an implementation layer. I may have a clear design specification of the algorithm but development issues when trying to implement the algorithm itself into actual source code.

The original point was that code works as designed Basicly coding is design work, and can be seen as the last iteration of the whole design process.

Other more "senior" developers often snicker when I don't use an inline LINQ statement that spans several lines that connected to an automagic data source, that requires EF v (who cares) to be installed before it can be debugged. Instead, I like a couple of well intentioned class files and the .NET Framework. Sure, it may be more verbose but any idiot can debug it; and that is who will be replacing me.

If I see you’ve achieved the goal with minimum efforts in coding and maximum in thinking, for me you’re okay and I’ll be glad to work with you.
