An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

React Native + macOS + Clojurescript

Project Catalyst

Since the recent release of Catalina, macOS has shipped with the ability to allow iOS/iPAD apps to run on macOS without any modification via a featureset known as Project Catalyst.

This is exciting, as writing React Native + Clojurescript apps as a target for the desktop is much more compelling than a pure Electron app (imo).

The Pledge

One thing that always made me a little sad about transducers was how map lost its ability to iterate multiple collections in parallel. This is actually my favorite feature of map. For example:

(map + (range 5) (range 5 10))
=> (5 7 9 11 13)

One somewhat practical use of this is if you want to compare two sequences, pairwise, using a comparator. Though I wish that every? took multiple collections, this is an adequate substitute:

How Clojure's documentation can leapfrog other languages

Summary

I made a documentation generator that cashes in on Clojure's dynamism. See the play-cljs docs (a ClojureScript game library) for an example of its output.

The Problem

Like many of you, I've often wondered what my final regret will be on my deathbed. My best guess came to me in a dream recently. I was walking across the charred earth of an apocalyptic future world, maneuvering around the remains of the less fortunate. I was startled to find a young girl, barely holding onto her life. She murmured something to me. I asked her to repeat it, and she said more loudly: "I...wish your Clojure projects didn't have such crappy documentation."

Installing Debian 8.5 "jessie" on a Lenovo X1 Carbon 4th generation (20FB) - 2016

UPDATE 2018-02-24: I got a new Lenovo X1 Carbon 5th gen and tried to do the same setup with Debian 9.3.0. It was an utter failure because of some boot issues. I went with Xubuntu instead and everything works FLAWLESSLY. Xubuntu is beautiful.

I've had my mind on switching my development machine from a 13" MacBook Pro Retina to a Lenovo X1 Carbon running Linux for a while. The main reason is getting more familiar with Linux itself and also to have a more stable and minimal dev environment. So I finally got the machine and decided to install Debian 8.5 "jessie". Why Debian? Well, I tried installing Arch Linux once and couldn't get past getting wifi to work, and Ubuntu seemed like it added too much stuff. The choice was either Debian or Linux Mint. I went with Debian because it seems like it's the most stable.

Create a bootable USB stick

I followed the instructions at https://www.debian.org/releases/jessie/amd64/ch04s
