Scala is one of the JVM languages trying to dethrone Java. Currently Kotlin is leading this race by a lot, but Scala, Clojure, and Groovy are all quite popular, with JRuby being somewhat behind them in the race.This post is about Scala 2. Scala 3 is currently being developed, which plans to make fun...

Last time, we learned that transducers are just middleware for reducing functions. In the same way that Clojure’s Ring web application library uses middleware to wrap HTTP handlers, transducers are used to wrap and modify reducing functions.When we left off, we had just designed a new function, cc-f...

This is an experiment I am doing about introducing a bit of self-referential stuff in Chapter 13 of "Data-Oriented Programming. I was inspired by the "Gödel, Escher, Bach" masterpiece. Not sure yet, if it will make it into the official version of the book though. It depends on your feedback. ...

#!/usr/bin/env clojure;; A Festive Theorem;; About a week ago, a friend of mine who is not noted for his interest in pure mathematics, and;; whose identity I will conceal behind the alias "Sipper" caught me in the Wetherspoons and showed;; me a number theory proof (or at least most of one, we couldn...

In our last episode, we learned how we can re-implement many other Clojure collection processing functions such as mapv and filterv in terms of reduce. Were you able to implement some of the other functions we talked about like keep or group-by?In this post, we’ll start to look into Clojure transduc...

When it comes to understanding software application performance, software engineering often unfolds like a Chuck Norris action movie – fires, explosions, elevator fistfights. Often, these edge-of-your-seat gymnastics are triggered by the customer using your shiny new deployment doing ordinary things...

Haskell is a language that took the ideas of functional programming very seriously. Instead of being halfhearted like OCaml or various Lisps, Haskell took the most principled functional choice every single time.Before I get to the code, there are a few serious issues with Haskell I want to address u...

You can read mor...

In yesterday’s post, we took a look at reduce, one of the true workhorses of functional programming. In today’s post, we’ll see how we can use reduce to implement some other functions in the Clojure standard library.As we learned previously, reduce takes three arguments: a reducing function, an opti...

Juicy, but no. assoc? Nope. str? Nyet. fnil? Nein.My favorite Clojure function is reduce. Why reduce? Let me cou...
