Putting Aside the Ranger
Put aside the ranger. Become who you were born to be.
Nothing about my life, or this little story, is anywhere near as inspirational as when Elrond gives Anduril, forged from the shards of Narsil, to Aragorn.
In fact, there’s ample opportunity yet for crushing disappointment to steal the day. It’s my hope that writing this here, now, will put just enough pressure on myself to stick with what I’ve committed to do.
I simply choose to believe that we can all find inspiration to make small decisions to improve our lives, incrementally shedding the husks of older versions of ourselves behind us.
Not long ago (the end of March, 2016), I listened to an episode of the Changelog that had a profound effect on me. I’m not entirely sure what it was that made episode #198 different from other podcasts I’ve heard, featuring guests who shone light on some (to me) heretofore unexplored topic.
The Changelog has aired many such episodes over the years. This one stood out from the rest because, unlike previous installments, this particular show hosted a pair of guests who are co-authoring a book about Haskell, the functional programming language.
The gateway drug
Later, when writing the build harness for my team’s app, I used Ramda to wire everything together. I’m sure I got a lot wrong, but my appetite for functional programming had been whetted, and I wanted to learn more.
I wanted to learn the reference functional programming language. I wanted to learn Haskell.
The Haskell Book
When Chris Allen and Julie Moronuki were interviewed on the Changelog, what caught my interest was their unique team dynamic as a writing duo.
Chris has over six years of Haskell experience under his belt, as well as previous experience with other functional languages, like Clojure. His passion is clearly teaching. Surely, the ideal candidate to author a programming book.
Julie is a linguist and stay-at-home mom, with no prior programming experience other than Haskell. She’s been working with the language for about a year. Chris convinced Julie to let him teach her how to program, and along the way, Julie became the co-author of the Haskell book: Haskell Programming from First Principles.
To me the book promised a pedagogical rigor, combined with what was sure to be a fair amount of empathy for the beginner’s mind. I’d tried to read about Haskell before, but all I came away with was an esoteric vocabulary to describe mountaintop ideas I couldn’t comprehend.
In interacting with other Haskell learners I often hear that other materials leave them feeling like Haskell is difficult and mysterious, a programming language best left to wizards. It doesn’t have to be that way.
I found that point of view encouraging and refreshing. It was as if an impenetrable veil was about to be lifted.
An unexpected journey
I downloaded the free sample, and after completing it, I felt comfortable buying the early access edition of the book. At the time I purchased it, the book was complete but for three chapters remaining.
Today, I received the notification that the final chapters have been added. It looks like the authors are now busying themselves with various preparations to go to print with the hard copy.
As a challenge to myself, I’ve started reading the Haskell Book regularly. I’ve found it both very clear and incredibly challenging to this point – I’m just finishing up the sixth chapter: Typeclasses.
I’m being challenged to rethink much of what I know as a programmer, enough to the point where I suspect that, if the command line and general tooling weren’t serious issues, it would be easier for someone completely new to programming to pick up Haskell.
If for no other reason than to reinforce them for myself, I am planning future posts to discuss Haskell and functional programming concepts I’m learning as I get further into the book. Stay tuned!
