Software Engineering Week 4

    The most interesting thing I have learned about in my reading of "Software Engineering at Google" are how each of the various processes are executed. While I am familiar with most of the processes I've read about so far, including code reviews, unit testing and system testing, the manners in which these are executed at Google are different from how they have been executed in my professional experience. For code reviews in particular, Google engineers ensure they invite various other software engineers to fill the roles of correctness and comprehension checking, language readability checking, and code owner. However, in my experiences this is not explicitly required. While a single engineer on the team often fills a couple of these roles, there wasn't an engineer specifically dedicated to carry out each of these tasks. Another interesting thing I learned was a recommendation about the use of the "sleep()" function in testing. While sometimes waiting is required in a test when waiting for an event to execute, it is true that using many of these in larger scale will increase test duration. Pivoting to a microsecond leveling polling technique with a timeout is an interesting method to combat this issue.
