A future version of Ember will come with a new templating engine known as HTMLBars.

The original motivation for HTMLBars was to allow helpers and properties to have better contextual information about what they were bound to.

So for example, consider a template like this:

<a href="{{url}}">{{link}}</a>

import { makeExecutableSchema, addMockFunctionsToSchema } from 'graphql-tools';
import { graphql } from 'graphql';
import GraphQLMock from 'graphql-mock';
import typeDefs from 'imports/startup/both/typeDefs';

// Make a GraphQL schema with no resolvers
const schema = makeExecutableSchema({ typeDefs });

// Creates random id
const revisedRandId = () =>

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.
