Hi, I'mBradPleased to meet you.

Using Nix to deploy a Haskell web app to Heroku
— 16 February, 2020

Deploying Ruby on Rails apps to Heroku has always been a delight, and now that they have a container registry other run-times are similarly delightfully deployable. No build-packs required.

with (import <nixpkgs> {});
dockerTools.buildImage {
  name = "hello";
  contents = [ hello ];

If you're like me, you develop on both macOS and Linux and are very much a creature of habit, then this may be of interest. It's a description of how I arrived at my current approach for maintaining a base development environment across the two platforms.

Getting close to the conceptual metal
— 27 January, 2020

Writing software can give us the ability to take a nearly impossibly abstract idea and use it to create a runnable program.

In this post we're to talk about "fundamental things" and see how much we can build with them.

type a × b =
  forall c.
    (a -> b -> c) -> c

type a + b =
  forall c.
    (a -> c) -> (b -> c) -> c

Deploying a fully automated Nix-based static website
— 21 November, 2019

{ config, pkgs, ... }:
  repo = builtins.fetchTarball {
    url = https://repo.tar.gz;
  imports = ["${repo}/module.nix"];

  services."site".enable = true;

I can't promise that this will take you five minutes (it won't). What I will say is this: if you'd like to learn more about Nix and NixOs then this may be interesting.

Servant's type-level domain specific language
— 05 October, 2019

Haskell has some very interesting type-level features, Servant is a great case-study in how they can be used to build a practical and feature rich library. This post walks through an example in an attempt to become more familiar with its inner workings.

type UsersIndex =
  Get '[JSON] [User]

type UsersShow =
  Capture "username" String
    :> Get '[JSON] User

type UsersAPI =
    :> (UsersIndex :<|> UsersShow)

Let's learn about lenses
— 21 August, 2018

type Lens s t a b =
  forall f. Functor f =>
    (a -> f b) -> s -> f t

_1 :: Lens (a, c) (b, c) a b
_1 = _

_2 :: Lens (c, a) (c, b) a b
_2 = _

Gaining an understanding of the Lens type has been on my todo list for a long time. So I finally bit the bullet and read up a little. These are (more or less) my notes as I went along.

You already know what Monads are
— 06 January, 2017

I sought to understand what the fuss was all about and I've now added to the mass of Monad Explainer posts on the internet.

readAFile().then(function (content) {
  return writeAFile(content)
}).then(function (report) {

Petrichor Ensemble — Gig Poster Detail

Petrichor (/ˈpɛtrɨkɔər/) is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek, petra, meaning ‘stone’, + ichor, the fluid that flows in the veins of the gods in Greek mythology.

Everything is connected, and the way it connects is kinda complex. I'd like to be more aware of my connections to people and the networks they're a part of.

As it stands these are all mock-ups rendered in SketchUp, the ~~dream~~ plan is to get this rendering in the browser from user input. Wild scaffolding.
