We recently needed to parse and modify some query strings while building Request Metrics. Query string parsing has never been pleasant in .NET, has it improved in .NET Core? We were familiar with HttpUtility.ParseQueryString() for the task, but that API has a major landmine. With the release of .NET Core, Microsoft took another swing at it.

But what happens when you have 100s of data points? What if your data source is noisy? That's when it's helpful to use a technique called linear regression. In this article Julie Kent shows us how linear regression works, and walks through a practical example in Ruby.
