Wednesday, 14 September 2022

- Survey: fill it out if you haven't!

- Quoc Nguyen: prefect extraordinaire!

- How'd it go?

- First 5 days' goals
    - Set up your computer
    - Start using git (version control software)
    - Start using Unix
        - Move files around
            [let's talk about file systems & paths]
        - Notion of working directory and moving
                your perspective around
        - Looking at files
    - Pick a GUI text editor and use it with your git repo
    - Start thinking about the needs of your users

- Next
    - Test-driven development
    - Unit tests in Python
    - Command-line design and implementation
    - Processing CSV's in Python

- Today
	- Ask questions about setup, Unix, or anything else.
	- Work on Unix tutorial
	- Meet your git partner
	- Done with everything else? Start git assignment.

- Unix mini-challenges
	- What does pwd do? What does "pwd" stand for? Explain
		the meaning of "p", "w", and "d"?
	- How do you change your working directory to your home
		directory? (And what does "home directory" mean?)
	- Suppose your home directory contains two subdirectories
		"cs257" and "cs251". Suppose your working directory
		is cs251 and you accidentally created a file called
		unixnotes.txt in cs251 instead of cs257. How do you
		move unixnotes.txt to the cs257 directory?
	- [this will require a bit of research]
		In a directory full of image files, change (in one Unix
		line) all of the *.jpeg files to *.jpg
