Clean Code - Writing Meaningful Names

In this episode, we take our first dive into the book Clean Code by Robert Martin and specifically we talk about writing meaningful names for all things code related.  You'll be amazed at how following some decent rules that you can start naming things that will help you and fellow coders understand your code at a glance.

Resources we Like Clean Code Clean Code by Robert C. Martin Even though we're giving our thoughts on the various ideas throughout the book, Clean Code has tons of excellent sample code that really helps drive the points home. We can't recommend it enough - it's probably one of the few books EVERY developer should read and revisit from time to time. http://amzn.to/2cryvJR Tip of the Week Allen: Implementing OAuth in ASP.NET for a number of providers http://www.oauthforaspnet.com/ Michael: Get out there!
