Simple ReactJS component to support a navbar becoming visible after the user scrolls down the page.

Ensure you have raf installed: npm install --save raf

This is the code for the component.

import raf from 'raf';

export default class ScrollInNav extends Component {
  static propTypes = {
    scrollInHeight: React.PropTypes.number

Lambdas that Rock, Rewriting Python on the Fly

For a long time, I've had a distaste for the syntax of lambda expressions in python.

add1 = lambda value: value + 1
print add1(1)
>>> 2

Compared to syntaxes for the same effect in other languages (like c#), it seems clunky.

                Stick this in the RobovmLauncher class created by the libgdx project ui for mopub ads. This is interacting with blueriver's robovm mopub bindings. You can use this to set up admob with libgdx on iOS.

          public boolean didFinishLaunching (UIApplication application, NSDictionary options) {
        

        

          
                  super.didFinishLaunching(application,options);
        

        

          
                  // We need a view controller to see ads.
        

        

          
                  //rootViewController =  ((IOSApplication) Gdx.app).getUIViewController();
        

        

          
                  // If you are already using a UIWindow with a root view controller, get the root view controller (f.e. LibGDX):
        

        

          
                  rootViewController = ((IOSApplication)Gdx.app).getUIViewController();
        

        

          
          

        

        

          
                  // Create a MoPub ad. In this case a banner, but you can make it any size you want.
        

        

          
                  final MPAdView banner = new MPAdView(BANNER_AD_UNIT_ID, MPConstants.MOPUB_BANNER_SIZE);
