Bits of Learning

Learning sometimes happens in big jumps, but mostly in little tiny steps. I share my baby steps of learning here, mostly on topics around programming, programming languages, software engineering, and computing in general. But occasionally, even on other disciplines of engineering or even science. I mostly learn through examples and doing. And this place is a logbook of my experiences in learning something. You may find several things interesting here: little cute snippets of (hopefully useful) code, a bit of backing theory, and a lot of gyan on how learning can be so much fun.

A Software Engineering Practice Problem

Suppose team A has built a module M, which is used by many of the products of A. Team B borrows M from A. While using it, they find a bug in M. In that process, they also create a fix which works for them. The question is: What should be the process by which the bug is reported to team A, and how should the fix be incorporated?

The potential difficulty is that there are many products that A had made which use M. Hence, if the fix is incorporated in the next version, all those products need to be regression tested.

Of course, it's a very common problem, and people must be doing something to solve it at their own level. Can we note down some common-sense technique here?
