I’m looking forward to the Sass Fundamentals workshop! A few notes to ensure you’re set up in advance are below.

See you soon!

Node.js

You’ll need a relatively recent version (v4.5 or newer, v7 ideally) of node.js installed. On OS X, a great way of doing this without disturbing your existing dev environment is to install NVM. Installation instructions are here.

Introduction to Angular

Angular (aka Angular 2) is a new framework completely rewritten from the ground up, replacing the famous AngularJS framework (aka Angular 1.x).

More that just a framework, Angular should now be considered as a whole platform which comes with a complete set of tools, like its own CLI, debug utilities or performance tools.

Getting started

NetworkManager WiFi Power Saving

NetworkManager supports WiFi powersaving but the function is rather undocumented.

From the source code: wifi.powersave can have the following value:

NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting
NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave

This file shows how to use the geoConicConformalSpain projection from d3-composite-projections.

To change the file, edit draw.js and run

browserify draw.js| uglifyjs > bundle.js

The dependencies are installed with:

npm install d3-composite-projections d3-geo d3-request d3-selection d3-transition topojson
