How to increase the root partition size on Fedora

Boot up with an Fedora Live USB stick.

Run vgs to check if there's any space:

$ sudo vgs
  VG     #PV #LV #SN Attr   VSize    VFree
  fedora   1   3   0 wz--n- <237.28g    0

When posting a theme make sure it has

title (theme name or whatever)
link to a gist or github repo with theme files
screenshot attached (just drag an image onto a comment area)

Setup Travis Deploy (macOS)

see Travis documentation

gem install travis

ssh-keygen -t rsa -b 4096 -f 'github_deploy_key' -N ''

cat github_deploy_key.pub

copy public key and set as a deploy key on github e.g https://github.com///settings/keys

What / Why

Deploy key is a SSH key set in your repo to grant client read-only (as well as r/w, if you want) access to your repo.

As the name says, its primary function is to be used in the deploy process in replace of username/password, where only read access is needed. Therefore keep the repo safe from the attack, in case the server side is fallen.

Let's build a binary tree of strings in Rust. To recap, each node in a binary tree:

must have a value

	If you want to login as root using SSH or SFTP you need to edit the config of SSHD, do this:

	Login, and edit this file: sudo nano /etc/ssh/sshd_config
	Find this line: PermitRootLogin without-password
	Edit: PermitRootLogin yes
	Close and save file
	reboot or restart sshd service using: /etc/init.d/ssh restart
	Set a root password if there isn't one already: sudo passwd root
	Now you can login as root, but I recommend you using strong password or ssh-keys

	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

	# use the latest ubuntu environment (18.04) available on travis
	dist: bionic

	language: go

	# You don't need to test on very old versions of the Go compiler. It's the user's
	# responsibility to keep their compiler up to date.
	go:
	- 1.16.x

	# standard compile options for the c++ executable
	FLAGS = -fPIC

	# the python interface through swig
	PYTHONI = -I/usr/include/python2.6/
	PYTHONL = -Xlinker -export-dynamic

	# default super-target
	all:
	g++ -fPIC -c kitty.cc -o kitty.o
