Getting deeper into functional programming

I've been so busy that I cannot find time to write a blog post anymore. But since 2012,  I've been playing with the Scala programming language and built projects using Play framework. I find Scala very concise and elegant as a programming language. The only issue I have with it is the syntax. When it gets too much into functional programming it gets harder to understand.

To fully submerge my thought into functional programming, I decided to take an online course "Introduction to Functional Programming" in edx. (https://www.edx.org/course/delftx/delftx-fp101x-introduction-functional-2126#.VFEX416nS5E). The course uses Haskell as a language, and it is taught by Erik Meijer.  I hope to finish this course soon, and hopefully widen my knowledge about functional programming.
