But C isn't as maintainable as nice Java apps, and it's as simple as that. Basically, I'm after the most powerful interface possible to Asterisk, but trying to make it as friendly as possible to code things against. As far as our organization is concerned, that pretty much means Java objects.
So you bought that line of Marketecture didn't you. I think there are
several large open source projects that prove that C is maintainable.
Maintainability is really a function of organization. If you can't be
organized, you will not produce very maintainable C code.
Stop it right there. This mailing list isn't the place for language holy wars. Java is the tool of choice for our organization, and therefore Java code is more maintainable within it. Everyone here talks Java. Not everyone talks C. If we hire less good programmers, Java hold their hand and enforces structure in a way that C doesn't. I'm not arguing that decent C code isn't maintainable. I'm stating that in our particular case, Java fits the bill better. It's that simple.
As for this:
It all comes down to the number of CPU cycles needed to perform a given function. When doing real time processing, a few cycles here and a few there can add up to make a real difference. Object Oriented is nice for ease of writing/maintaining code but all of those objects have blocks of code behind them. A slight inefficiency there can really impact performance. Sure we have faster processors and lower cost memory every 6 months but thats no excuse for not writing the most efficient code possible.
You're entirely wrong. Provided it's fast enough, it's all about maintainability, extensibility and scalability. The bottom line is that we're in it to make money. If it runs on hardware that's $100 cheaper, but takes four times as long to develop, then total cost is much higher. If it's easy to repurpose it at a later date, or easier to have someone unfamiliar with the codebase to come along and customize it, that's worth a lot. Both are significant, but maintainability is much more important than performance, as that's where the real cost lies.
