Arquitecturas Concurrentes — Episodio 7: Just call me Maybe y otras estructuras

En los episodios anteriores surgieron los conceptos de falla, no determinismo y excepción. También vimos dos estructuras que nos permitían abstraernos sobre CPS: promesas y streams observables…

My Journey into Haskell

I first encountered Haskell in my Programming Languages class at Harvey Mudd. In that class, my experience felt like just a constant cycle of:

1. Write code that doesn't compile
2. Make arbitrary changes until it compiles
3. goto 1

I am a long time imperative programmer that just recently picked up learning Haskell on a recommendation. It seems far more intuitive to me for solving problems of all kinds. I honestly only see the value of imperative programming where you need to be to the metal, like coding for Arduino. We purposely make things harder for ourselves by managing…

Grasping Haskell: functors, applicatives and monads (part 2)

Applicative functors

This is the second part in a series, the previous part covered Functors.

Grasping Haskell: functors, applicatives and monads (part 1)

Let’s say we have a value: 5.
We know how to apply a function to this value:

(* 2) 5

would equal 10.
