Using ADB to control Accessbility settings for easier testing with Android Emulators + Real Devices

It's a lot easier to test accessibility on the fly using ADB. This gist attempts to make the days of navigating through the Android device settings UI to change Accessibility settings obsolete.

These ADB commands will hopefully encourage Android developers to test and use their apps with common Accessiblility settings enabled.

Credit to James Nitsch for inspiring this, and for figuring out the put commands to enable these settings.

Shifting an unprivileged LXC container to privileged

Still experimental...

Assume that the unprivileged container test already exists. We want a privileged container called test2 to have the same rootfs as test.

Create test2

Create a privileged container first. Probably need to be the exact same OS as test1!

Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]). 
The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch. 
Following are the changes that I made to make it work.

$ sudo apt-get update
$ sudo apt-get install lirc

# Add the following lines to /etc/modules file
lirc_dev
lirc_rpi gpio_in_pin=18 gpio_out_pin=17

There are a few decent tutorials on how to setup hotspot on Linux, which I will share below, but this tutorial will focus on adversities that you without doubt will face while setting up your AP.

For AP setup we will need:

• Hostapd utility
• Some dhcp utility
• A bit of patience (that was for my case)

How do I know that my WiFi adapter supports AP mode?

In terminal type sudo iw list this command will show info about your wifi interfaces. Look for Supported interface entry, if AP is in it, that means your Wifi devices support hotspot mode.

The i3-wm does not come with a keybinding to lock the screen or a preconfigured auto lockscreen. This gist describes how to setup both using i3lock and xautolock. i3lock is a minimalistic lockscreen and xautolock monitors mouse and keyboard activities to automatically lock the screen after a certain time of beiing inactive.

First get the tools if neccessary. E.g. sudo apt install i3lock xautolock.

To setup the keybinding Ctrl+Alt+l (last one is a lowercase L) to lock the screen append the following lines to the i3 configuration file located at ~/.config/i3/config.

# keybinding to lock screen
