Welcome to IWETHEY!

New I'm considerably more skeptical about components
It's hard to find a component that does exactly what you need - software, electrical, or mechanical. Normally quite a bit of extra stuff is required to get it do what you want.

Current software component technologies like DLL's, ActiveX, COM, etc have their issues. Versioning can be really fun. Getting everything registered and working can be lots of fun. Commercial components are often a major pain in the butt - not just the cost, but the headaches installing it on development machines, license keys, etc.

The component model limits what can be done - for example, I can develop much quicker using only dynamic language such as Python than to split everything into COM objects, just because COM does not support Python's advanced features.

That's why I think the way forward is dynamic languages that can be used to bind together existing libraries and components quickly - and add the necessary logic on top - not "drop and connect" of existing components.

BTW, the "component vision" was promoted by Sandstone (Objective C guys) in the mid 80's. It was a failure then. It might work if everyone agreed on one language, and one way to do everything. But that's not reality. (And, yes, the world might be a better place if Objective C was dominant instead of C++. But there still is no silver bullet.)

New Well said.
I'm no programmer, but I know this component stuff has been a Holy Grail for a long time. As you say, they only go so far, and interoperability of components is a big problem.

Maybe in 10 years computers will be fast enough and storage will be cheap enough that a GNU library of 10^10 robust components that can be extended easily in a bullet-proof manner will exist, but I'm not betting on it either. Maybe such components would cover 50% of standard business programming by then, but they won't cover the "cool" and "interesting" stuff that people enjoy working on. So there will always be a need for new custom code that doesn't exist in some drag-and-drop framework. At that point, robust tools and processes need to come into play.

Cheers,
Scott.
New Well, we've already got 10^10 components...
Have you taken a look at .NyET's CLR recently?

"So don't pay attention to the approval ratings that say 68% of Americans disapprove of the job this man is doing. I ask you this, does that not also logically mean that 68% approve of the job he's not doing? Think about it. I haven't."

                     What do you mean, traditionally? - (admin) - (10)
                         I mean what they mean in their documentation - (ben_tilly) - (9)
                             That's character set, not numeric. - (admin) - (8)
                                 So we were talking past each other -NT - (ben_tilly) - (7)
                                     The example you gave was of numeric sort not working. - (admin) - (2)
                                         No, it was not of *numeric* sort not working - (ben_tilly) - (1)
                                             Nevermind me, I'm tired tonight. -NT - (admin)
                                     There's a lot of that going on -NT - (tuberculosis) - (3)

                                             Whatever - (tuberculosis) - (1)
                                                 Who says irony is dead? -NT - (admin)
             The problem with hardware is deeper - (tonytib)
         Good luck with that - (warmachine)

For Wade, it is to wonder.
