A useful shell script that wraps Android adb commands when multiple devices or emulators are connected. The script will prompt for a device or emulator to run the command against, if it detects multiple devices / emulators.
#!/bin/bash
# This is a wrapper for adb. If there are multiple devices / emulators, this script will prompt for which device to use
# Then it'll pass whatever commands to that specific device or emulator.
# Run adb devices once, in event adb hasn't been started yet
BLAH=$(adb devices)
# Grab the IDs of all the connected devices / emulators
IDS=($(adb devices | sed '1,1d' | sed '$d' | cut -f 1 | sort))

A SimpleSectionedRecyclerViewAdapter: use this class to realize a simple sectioned `RecyclerView.Adapter`.

You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Use wget to snapshot a page and its necessary visual dependencies

Use wget to mirror a single page and its visible dependencies (images, styles)

Money graphic via State of Florida CFO Vendor Payment Search

Graphic via State of Florida CFO Vendor Payment Search (flair.myfloridacfo.com)

This is a quick command I use to snapshot webpages that have a fun image I want to keep for my own collection of WTFViz. Why not just right-click and save the image? Oftentimes, the webpage in which the image is embedded contains necessary context, such as captions and links to important documentation just incase you forget what exactly that fun graphic was trying to explain.
