What is the most solidly designed and implemented software system/framework/application that you've come across?
It seems like TDD, SOLID principles, OO design patterns, and things like that can be easily theorized on podcasts and blogs using really simple examples, but it's hard to imagine developing large systems that fully live up to these standards, without an explosion of code. At my company, doing full TDD seems almost out of the question with our time constraints.
If anyone can point me to any good open-source projects, I'd really like to dig in and see what good TDD/SOLID/etc. looks like. Thanks.

Design examples include operation systems, webpages, mobile devices or even the new cloud computing paradigm. Software design is both a process and a model. The design process is a sequence of steps that enables the designer to describe all aspects of the software for building.
▪ Software design and implementation is the stage in the software engineering process at which an executable software system is developed. ▪ Software design and implementation activities are invariably inter-leaved.
Good software design encompasses the necessary software components of modules, data objects, external interfaces, and more. All dependencies between modules and other virtual entities should be harmonized and comply with inheritance principles.
The key is that the user experience design needs to happen before the implementation begins. This is one situation where sequential is important. The requirements and design happen together, and then implementation and test can happen together, and then implementation and test can happen together.

They Write the Right Stuff
But how much work the software does is not what makes it remarkable. What makes it remarkable is how well the software works. This software never crashes. It never needs to be re-booted. This software is bug-free. It is perfect, as perfect as human beings have achieved. Consider these stats : the last three versions of the program -- each 420,000 lines long-had just one error each. The last 11 versions of this software had a total of 17 errors. Commercial programs of equivalent complexity would have 5,000 errors.
