My approach to handling revision control would be to post the code on SourceForge or GitHub so everyone can view it. Also, I will post the checklist from the last revision to make sure that any unsolved issues are resolved. It’s up to us to figure out which processes and technology will help us make it reality.

Continuous Integration is basically a practice that requires developers to integrate code into a shared registry for easy collaboration. One programmer act as a “driver.” Other acts as an “observer” who continuously monitor the progress of a project to identify problems.

Test that ensures recovery without data and functionality loss after a failure is called Resiliency tests. Pair programming is an engineering practice of Extreme Programming Rules. In this method, two programmers work on the same system, on the same design/algorithm/code. Dogpile effect is referred to the event when a cache expires, and websites are hit by the multiple requests made by the client at the same time. In this system when value expires, the first process acquires the lock and starts generating new value. It also allows you to build a writable Git mirror of a local or remote Subversion repository.
