'Users hate change'

This week NN Group released a video by Jakob Nielsen in which he attempts to help designers deal with the problem of customers being resistant to their new site/product redesign. The argument goes thusly:

Humans naturally resist change
Your change is for the better
Customers should just get used to it and stop complaining

There's slightly more to it than that, he caveats his argument with requiring you to have of course followed their best practices on product design, and allows for a period of customers being able to elect to continue to use the old site, although he says this is obviously only a temporary solution as you don't want to support both.

Installing Babel

The following are a few important npm packages.

Core Babel and access to Babel:

babel-core: the core compilation machinery and plugin infrastructure for Babel. You will rarely need to install this package, because other packages such as babel-cli have it as a dependency, meaning that it will be automatically installed when they are installed.
babel-cli: a command line interface to Babel. It includes the following commands:
babel-doctor detects common problems with your Babel installation.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

The future is here: Classless object-oriented programming in JavaScript.

Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.

Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.

I think it's really, really sleek, and this is what it looks like:

function dog(spec) {

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
