1. Determine the package name of the app, e.g. "com.example.someapp". Skip this step if you already know the package name.

adb shell pm list packages

Look through the list of package names and try to find a match between the app in question and the package name. This is usually easy, but note that the package name can be completely unrelated to the app name. If you can't recognize the app from the list of package names, try finding the app in Google Play using a browser. The URL for an app in Google Play contains the package name.

2. Get the full path name of the APK file for the desired package.

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:

/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp 
server, but for some reason omit a client connecting to it.  I added an 
example at the bottom.

Save the following server in example.js:
*/

var net = require('net');

The filter and zoom rules in the sample stylesheet above will apply a smoothing/blurring effect to text elements. In the sample stylesheet, these rules are applied to all headers, paragraphs, list items, and table cells, but in practice, you will want to tailor the application of the smoothing effect to only those elements rendering with significant aliasing.

Nota Bene: the filter appears to place an overflow: hidden-style block around the elements being smoothed, so do not apply these rules directly to elements that need to scroll, or which contain absolutely positioned elements that appear outside the boundaries of the element itself.
