Headless Raspberry PI + SSH + Wifi (Raspbian Stretch)

1. Burn the Raspbian image to the SD card

2. Enable ssh

For security reasons, ssh is no longer enabled by default. To enable it you need to place an empty filed named ssh (no extension) in the root of the boot disk. touch /Volumes/boot/ssh

3. Add network info

Create a file in the root of boot called: wpa_supplicant.conf. Then paste the following into it:

country=US

Assign the .local Domain to Your Raspberry Pi

Assign the .local Domain to Your Raspberry Pi

sudo apt-get install avahi-daemon

Once the installation process is complete, you don’t even have to reboot the device. Your Raspberry Pi will begin immediately recognizing local network queries for its hostname (by default “raspberrypi“) at raspberrypi.local.

Moving commits to a new branch

WARNING: This method works because you are creating a new branch with the first command: git branch newbranch. If you want to move commits to an existing branch you need to merge your changes into the existing branch before executing git reset --hard HEAD~3

git branch newbranch 
git reset --hard HEAD~3
git checkout newbranch
