These functions are built on top of an older background processing system called WebJobs. While Functions have largely eclipsed WebJobs, there remain certain [situations][webjobs-vs-functions] where the latter is still a better fit. Read more on Creating Azure WebJobs in F#…
I recently attended the Progressive F# Tutorials event in DUMBO, New York. It was a really great experience, and I think much of that is due to the way it was both a conference and more than a conference. Specifically, many of the talks featured hands-on tutorials, which provided a great opportunity to learn and digest new things.
For example, after opening remarks by Don Syme — F#’s original designer — I went to a session where he taught us about F# Compiler Services by providing a sample project with exercises to complete. He then went around from table to table helping anyone who was struggling. Quite naturally, this also encouraged us to work together with the others at our table, and we enjoyed getting to know each other and working together to solve the exercises. All in all, I found it a much more satisfying learning experience than just slides and a demo.
I also really enjoyed that afternoon, where Jack Pappas talked about writing compilers in F#, and his sample project with exercises even went so far as to include NUnit tests. That really struck a chord with this test-driven developer, to the extent that I got so excited about going from red to green I initially missed one of the exercises that didn’t include a failing test.

Recently, I’ve been playing with the F# programming language in my free time. One barrier that I ran into was the fact that I don’t have a Windows machine, meaning I had to use the Mono runtime on my Macbook. This presented some challenges that I had to work through.
So, why was I playing with F# in the first place? I had been looking for a language to fix some frustrations that I had with my current toolset:
- Lack of static typing that isn’t painfully repetitive (Java)
- First class support for common functional programming idioms – e.g. immutable by default, option types, pattern matching, etc. (All of the above)
I also wanted to take the opportunity to get some experience with the Microsoft/.NET ecosystem. Since the Microsoft stack is incredibly popular at many companies, including some of our clients, it seemed like a solid bit of knowledge to have. Also, I was excited about the possibility of using the Xamarin stack to create mobile apps with F#. Read more on Running F# Using Mono and Unix…
Like a lot of Atoms, I’m a bit of a programming language nerd. (For the record, I’m also a bit of a human language nerd.) So it was very natural that, after working in .NET using C# for a several months, I wanted to give F# a try.
For those unfamiliar with F#, it is a “functional first” language in the .NET family that is most similar to OCaml or Haskell. It is compiled and statically typed, but the type inference is really powerful and removes almost all of the boilerplate you see in languages like C# or Java.
I recently spent several days familiarizing myself with the basics of F#. For convenience, here are the ones I found most helpful. Read more on Resource Roundup: Getting Started with F#…
