Sometimes I would like to know how a cool software is made or the brilliant architecture behind a new fancy web service; but the software is not open-sourced and the web service has no public documentation.
Do you have any techniques to discover some hints on how a software is made?
Is it possible to do it?
Do you know some site that publish architectures/technologies used by softwares/web service?
EDIT:
Found this for Windows software
The best site for reading about the architecture of hot web sites is definitely High Scalability. It has lots of stories covering different aspects of architecture, not just scalability. It covers the usual suspects – eBay, Facebook, Google – but also some more obscure sites as well, such as our own StackOverflow. The articles generally combine a summary of whatever is in the public domain plus informed analysis. The site also includes interviews with sites’ architects.
