Hi David

I'm impressed with your back ground and your responsibilities at 37signals. When researching your profile I also found that you have 4.8K followers and have been starred 29 times on GitHub. This speaks volumes to your work and your high technical expertise. I'd love the opportunity to speak with you about a Ruby Engineering role I'm currently working on for Heroku. I'd like to share more details about the position and find out if you or anyone you know would be interested.

Heroku is a Platform as a Service (PaaS) that lets you deploy, run and manage applications written in Ruby, Node.js, Java, Python, Clojure and Scala. Heroku is owned by Salesforce however, we operate as a completely separate entity. This allows us to maintain our technology, culture and the formula that has made us so successful.

Anyway, it would be great to set up sometime to chat. I am more than happy to answer any questions that you might have and it would be great for me to hear about what you are looking for in any potentia

A small sampling of external projects initially built for Ember use but designed to be used standalone:

• Handlebars - templating engine
• simple-html-tokenizer - an HTML5 tokenizer
• HTMLBars - alternate HTML-aware Handlebars backend
• morph - text-node placeholders for data binding systems
• RSVP - fast, lightweight promise library
• route-recognizer - just the recognition part of a router
• router.js - hierarchical states and transition-based router
• dag-map - graph library

An example of a simple form

Consider the following markup:

<form class="root" state:theme=dark state:compact>
  <div class="input-area">
    <label for="username" class="label">Username:</label>
    <input id="username" class="input" type="text">
  </div>

// It's composable

const compose = (a,b) => v => a(b(v))
const isValid = valid => fn => (...p) => valid(...p) && fn(...p)

const hasTwoParams = isValid((...params) => params.length === 2)
const firstParamIsArray = isValid(a => Array.isArray(a))
const hasTwoFirstArray = compose(hasTwoParams, firstParamIsArray)
const myValidatedFn = hasTwoFirstArray((a, b) => console.log('It worked', a, b))

Why the jQuery Abstraction isn't needed.

(One needs some form of browser normalization so that modern features works, no-one is doubting that).

Abstractions that aren't needed

Selectors

warn on empty jquery selection

Graduated to github: https://github.com/devinrhode2/StrictjQuery.js

But for the simple version (quite possibly better): (wait no its broke use the one on GH)

Warns when you have an empty jQuery selection, unless you do $('foo', failsafe);

 $.badSelectorAction = function badSelectorActionFn( selector, context ) {
