Prototyping

Session 1

Unix

Unix is a portable, multitasking, multiuser, time-sharing operating system (OS) originally developed in 1969 by a group of employees at AT&T.

Raspberry Pi

Raspberry Pi is the name of a series of single-board computers made by the Raspberry Pi Foundation, a UK charity that aims to educate people in computing and create easier access to computing education.

Session 2

Session 2 pad

Creating a key

- Key for our user in pi (created in the first session)
- Our ssh key

Output in terminal when creating a key

Making a secure login for the pi with our key

ls -a gives hidden files

Question: How do we create hidden files?

Git

The software that runs git softwares or companies based on git (GitHub,gitlab or git.xpub.nl)
It’s a way to keep track versions of projects (text, code, websites, images)

A git project will have a parent folder.
Parent folder- might have other folders in it with other files

git init- stating the git program in your folder (makes a git. Folder)

Command to make git track your project:
git status- shows in red what isn’t tracked and in green what is tracked
git add <file name>- starts tracking that file or files
git commit -m <“a comment about what change has been made”>- saves the version in the .git folder

HEAD- like a brunch, the version I am in right now
MASTER- like in Abstract

git diff <file name>- shows the what have change since previous commit
git checkout -- <file name>- deletes the changes that where made and comes back to the last commit
git add -u - will add all the tracked ones
git reset HEAD <name of file> - Undo a commit
git log- shows the commits

Publishing on XPUB GIT

Create a new repository
When you create it gives instructions (choose SSH in the toggle)
pushing= publish to git website

Pushing from git to raspberry pi

- For now raspberry pi will just host our website
- On the git website we see the published file in dashboard
*** sudo let’s you install thing on pi- sudo apt install <software name> ***
*** sudo su- you can be someone else ***
use HTTPS link (top right)
Command to clone to pi:
git clone <HTTPS link> name the new folder

Work flow

Clone to your computer the folder from GIT (with the ssh url)
Then you can pull changes from the GIT
Or push changes back to the GIT
