Chaining promises

Chaining promises in ClojureScript is best done using the thread-first macro, ->. Here's an example of using the fetch API:

(-> (js/fetch "/data")
    (.then (fn [r]
             (when-not (.-ok r)
               (throw (js/Error. "Could not fetch /data")))
             (.json r)))

Installing Arch Linux with Full Disk Encryption

If you're aiming for a seamless Arch Linux installation in UEFI mode, follow along as this guide will walk you through the process step by step. We'll be using LUKS (Linux Unified Key Setup) and LVM (Logical Volume Manager) partitions on LUKS to achieve full disk encryption.

Note: I have updated this doc for UEFI mode. For those with BIOS/MBR systems, you can refer to the previous version, but keep in mind that it might be outdated and no longer accurate.

If you're only interested in installing Linux and not setting up dual boot with Windows, feel free to skip the Windows-related sections.

; To begin demonstrating the problem, we first need some

Conaws

;  In case anyone else is interested, here are a few specter functions I wrote that will 
;  find all the nested maps inside a composite datastructure, 
;  assign each of them a temporary id
;  then it'll pull it apart into a list, 
;  and replace all references to the map with its id

(ns extract-maps
  (:require [datascript.core    :as d]
            [com.rpl.specter    :as sp
                                :refer [ALL LAST MAP-VALS FIRST subselect

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

Install Atom

Download Atom

The Atom documentation is excellent. It's highly worth reading the flight manual.
