Thesis: Housing can be affordable to the purchaser and profitable to the developer. For example, a finished studio apartment could be available at $700/mo, or a three-bed at $1300/mo, and the developer who builds it will consider the ROI on the project/investment to be exceptional.

The need to do something tends to trump the need to understand what needs to be done. And without data, anyone who does anything is free to claim success.

Housing, broadly, is often considered a political issue, to be fixed by politicians.

I'll be quoating broadly from a recent seminal book by Urban Economist Alain Bertaud, specifically from Chapter 6: Affordability (p 219).

I often write detailed walk-throughs of difficult learning projects I take on.

This document serves as the same, a bit of an active scratch pad, and a way to quickly ask detailed questions of my team, and perhaps provide detailed answers for my team.

currently trying: USB-C->DisplayPort cord with SwitchResX to "force" the display up to a reasonable level

My home office setup has suffered some problems of late that are driving me insane.

The most annoying is my wired mouse. I use a wired Redragon Mammoth hooked up to my USB-C hub, and it started giving me problems when dragging anything. Like... a file, a screenshot, a window, it would rapidly (dozens of times a second) "drop" what I was dragging and then pick it up again.

This had extremely unpredictable effects, and was highly disruptive to my workflow.

I don't think my mouse is failing (my bluetooth mouse works fine, and for a variety of reasons I think the problem is my monitor is running at 30hz, not 60. more on that later.)

"Process" is greater than everything

Having a good process is how you go about doing anything that takes a long time and is hard. A good process can be a faithful tool to help you learn dozens of things, now, and five years from now. It's flexible and it's powerful.

One of the biggest pieces of "having a good process" is "taking plentiful notes, easily and quickly"

I won't try to convince you. Here's Arique, currently in Mod 1, on how she's made use of this general process:

class Object
  def exceptional?

Course = Struct.new(:name, :duration) do  
  def duration=(new_duration)
    self[:duration] = Duration(new_duration)

Double inject. What does it mean?

i want to know how long it takes to do some stuff. I've got some code like this:

def count_stuff(list)
  list.inject([]) do |results, item|
    results << get_results_from_something_else(values)
  end.flatten.uniq

I needed a URL validator - it needed to check that URL's had HTTP or HTTPS at the beginning. I initially wrote a "before save" action, but didn't like it cluttering up my model. I found a reference to basically "monkey patching" Rail's default Validator class, so that's what I did!

# concerns/url_validator.rb
require 'uri'

class UrlValidator < ActiveModel::Validator

  def validate(record)
    if record.url?

Better workflow (leads to) better questions (leads to) better jobs

We'll cover two things:

1. Have a great workflow
2. Ask great questions

On cleaner controllers

A few days ago, I worked on a project that was mostly about serving up basic store data (modeled after Etsy) to an API.

We had a few dozen end-points, and all responses were in JSON.

Most of the action happened inside of our controllers, and as you might imagine, our routes.rb file was bananas.

One of the instructors made an exceptionally simple suggestion, I was embarrassed to not have seen it.
