How a bug in Visual Studio 2015 exposed my source code on GitHub and cost me $6,500 in a few hours

I watched a lot of talks and read a lot of articles relevant to Angular performance, and this post is the summary of my findings.

Share your knowledge often and in public. This is one of my favorite ways to make knowledge stick; to share what I’ve learned with others. 

This is my personal blog, where I share about the people I meet, the books I'm reading, and what I'm learning. I hope that you'll join the conversation
