Meta-Non-Fungible Token

Non-fungible tokens (NFTs) are all the rage these days, but their current manifestation (ERC721) is inefficient. It is not possible to move multiple tokens at the same time or package multiple tokens for e.g. deposit into a plasma child chain.

Contract pseudocode

The following is a new design for an NFT token that allows aggregation of assets. The rest of the functionality can be inherited from ERC721.

contract NFT {
 tokens mapping(address =&gt; mapping(bytes32 =&gt; uint));

Here are some of the examples of Reactive Programming libraries I've found in Purescript and what I've thought about them so far:

Purescript Behaviors: https://github.com/paf31/purescript-behaviors

I've never used a library with truly continuous Behaviors, so this was really neat to try out for me. Really nice to use and comes with utilities for working with browser events already, and gives you good Event modules for picking your sampling options as necessary.

I will probably use this library for all of my future uses.

Purescript Signal: https://github.com/bodil/purescript-signal

ZEFR Engineering Onboarding Initiative

There are 7 key goals of the EOI:

New Hire feels warmly welcomed
New Hire knows who his or her Manager, Tech Lead, Product Manager, Team, and Department Heads are
New Hire understands the product or service he or she will be working on and the value it generates for ZEFR
New Hire knows where the codebase & associated docs are
New Hire understands his or her day to day responsibilities, medium & long term goals
New Hire is spun up, and opens a PR on their first week
New Hire is ready to come in the next day and hit the ground running

Note: I'm not involved in Prepack in any way — please correct me if I say anything incorrect below!

A few people have asked me if Prepack and Svelte are similar projects with similar goals. The answer is 'no, they're not', but let's take a moment to explore why.

What is Prepack?

Prepack describes itself as a 'partial evaluator for JavaScript'. What that means is that it will run your code in a specialised interpreter that, rather than having some effect on the world (like printing a message to the console), will track the effects that would have happened and express them more directly.

So for example if you give it this code...

	/*

	(updated by askmike) @ 30/07/2016

	*/
	// helpers
	var _ = require('lodash');
	var log = require('../core/log.js');

	if (typeof window!=='undefined' && navigator.serviceWorker && navigator.serviceWorker.controller) {
	let reloadOnNext = false;

	let pushState = history.pushState;
	history.pushState = function(state, title, url) {
	pushState.call(this, state, title, url);
	if (reloadOnNext===true) location.reload(true);
	};

	navigator.serviceWorker.controller.addEventListener('statechange', e => {

	return <Intersection>
