If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

1. Copy content of original credentials rails credentials:show somewhere temporarily.
2. Remove config/master.key and config/credentials.yml.enc
3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
5. Add and Commit the file config/credentials.yml.enc

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

CatTail

var assert = require('assert')
var util = require('util')

function test (inherits) {
    function Fruit () {

    }
    Fruit.prototype.round = false
    Fruit.prototype.sweet = true
    Fruit.prototype.eat = function () {}

tcaddy

# setup some input parameters
encrypted_decrypted = 'some string to encrypt or decrypt'
action = :encrypt # set to :encrypt or :decrypt
secret_key = 'abc123' # define shared secret key here

# encryption / decryption code...
cipher = OpenSSL::Cipher.new('AES-128-ECB')
if action == :decrypt
  cipher.key = [secret_key].pack('H*')
  cipher.padding = 0

Upgrading to Sierra for Ruby Devs

Often when upgrading to the latest OS X MacOS you have to do a few things to account for changing to underlying libraries. Here are the post-upgrade steps I took to get back to a fully operational state. I use homebrew and rbenv to manage my environment.

1. Get your Developer Command line tools upgraded.

To do this just run

$ xcode-select --install

Subdomaining Localhost with Rails 5

I've been following this blog post on how to set up an api-only Rails 5 application. One of the sections talks about creating a subdomain for your api

Rails.application.routes.draw do
  constraints subdomain: "api" do
    scope module: "api" do

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
