File Upload

This demo file will allow uploading to a capable endpoint (in this case /api/v1/fs/upload/). It is styled with Bootstrap as an example of the integration.

Change Git to Use SSH

Here's how to change git to use SSH.

The below scripts will automate the repo changes needed.

Get all Git Branches

When you git fetch sometimes you may not see all origin branches when you issue the command git branch -a or git branch -r.

This happens sometimes, if you change the remote repository with:

git remote set-url origin https://github.com/{owner}/{repository}

When this happens, exit .git/config and look for a hard-coded branch name in the origin:

Raspberry Pi PWM

This Python3 script was created to generate a square wave pattern from the GPIO of the Raspberry Pi. This signal was used to inject a signal into an electronics project, but could be used as the basis for any PWM needs.

The script is configured to output the signal

Check Temperature Throttling on the Raspberry Pi

This small Python script will display any temperature throttling messages on the Raspberry Pi.

Disabling IPv6

Source: https://www.leowkahman.com/2016/03/19/disable-ipv6-raspberry-raspbian/

Firstly, check for presence of IPv6 using ifconfig. You should be seeing a few lines containing inet6 addr: ....

To disable, edit a file: sudo nano /etc/sysctl.conf

Add the following line:

net.ipv6.conf.all.disable_ipv6 = 1

Shutdown Raspberry Pi with a Single Button

There are two methods:

Scripted Method
Boot Overlay Method (also below as "tl;dr")

tl;dr Version

Add the following to your /boot/config.txt and reboot:

	# Add to ~/.bash_aliases
	#
	# Random helpers
	alias cd..='cd ..' # Get rid of command not found error
	alias diff='colordiff' # Colorize diff output
	alias ping='ping -c 3' # Stop pings after three

	# Do system update/upgrade and cleanup in one shot
	alias update='sudo apt update && sudo apt --fix-broken install -y && sudo apt autoremove --purge -y && sudo apt clean && sudo apt autoclean -y && sudo apt upgrade -y'
	alias upgrade='update'

	log_tail.php?logFile=my.log
