Termux: Enable Wake-Lock

Smartphone Configuration

AutoHotkey - Media keyboard shortcuts

Control media with easy to remember keyboard shortcuts.

Even if you have a keyboard with dedicated media buttons, you'll find these keyboard shortcuts a lot easier to control the media on your computer.

Alt + Shift + Space : Pause/Play
Alt + Shift + n : Next
Alt + Shift + p : Previous
Alt + Shift + m : Mute
Alt + Shift + + : Volume up

EC2 User Data examples

Basic Windows local user with Administrator and RDP access

Add a local rdp user via user data at launch of a Windows EC2 instance. Note that this includes a password passed in thru both the user data and powershell command line and is a bad security practice because they can be viewed later. At a minimum, you should connect to the instance immediately after launch and change the password interactively. Also, delete the userdata from the instance after launch. More secure would be to connect the instance to a domain for authentication or use AWS native tooling to connect to the instance (e.g., AWS Session Manager).

<powershell>
# Be sure to set the username and password on these two lines. Of course this is not a good
# security practice to include a password at command line.

ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

Go to your computers/phones settings
Ensure Bluetooth is turned on
