DISCLAIMER

I am not responsible for any damages, loss of data, system corruption, or any other mishap you may somehow cause by following this guide.

This is mainly a step-by-step reminder/log for myself of how I installed Arch on my laptop. I am putting this out there in case it is useful for someone else, it is not intended to be an official guide. As a result, you may find that this guide is very tedious or lists a lot of unnecessary/intuitive steps or just straight up does things in a way that is considered bad practice. Apart from the latter, this is intentional, as I did not find these steps intuitive at all when

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
Install Git Server package via Diskstation

Here are some handy commands for connecting to servers and copying files about. These are all for Linux terminal / bash shell

Do cool things with ssh; log in & run command, find files in dir

# log into server
ssh [email protected] -Y 
# -X      Enables X11 forwarding. <- use this to enable X11 graphical windows, but this will eventually time out & you'll lose the X11 connection
# -Y      Enables trusted X11 forwarding. <- this one preserves your X11 connection while you're logged in

	# Import Dataset
	dataset = pd.read_csv('Data2.csv')
	X = dataset.iloc[:, :-1].values
	y = dataset.iloc[:, 5].values
	df_X = pd.DataFrame(X)
	df_y = pd.DataFrame(y)
