This is a quick tour of how to get started with NPM, how to use it, and how to fix it.

I'm available for tutoring and code review :)

You may reuse all my gists for any purpose under the WTFPL / CC0 (whichever you prefer).

Starting a new project

Create a folder for your project, preferably a Git repository. Navigate into that folder, and run:

JakeWharton

import org.junit.rules.TestRule;
import org.junit.runner.Description;
import org.junit.runners.model.Statement;

/** Got flaky tests? Shampoo them away. */
public final class ShampooRule implements TestRule {
  private final int iterations;

  public ShampooRule(int iterations) {
    if (iterations < 1) throw new IllegalArgumentException("iterations < 1: " + iterations);

Exercism and IntelliJ IDEA

So, you want to use IntelliJ IDEA for your Exercism.io Java exercises?

Here’s my workflow. Note, using IntelliJ IDEA CE 14.

Gradle setup

• [ ] cd to $EXERCISM_DIR/java/the-exercise
• [ ] Run gradle idea to generate the *.iml* and =.idea files/dirs

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. 
To use the support version of these attributes, remove the android namespace.  

For instance, "android:colorControlNormal" becomes "colorControlNormal".  

These attributes will be propagated to their corresponding attributes within the android namespace 
for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.

Android Studio Shortcuts (Mac)

Notes:

• Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
• Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
• A fairly complete shortcut list can be found here.

Useful symbols:
