Lectures 2: SageMathCloud

Heh everybody, remind me to start a screen recording!!!!!!!! I will forget.

• TA's Email: [e-mail]

• Professor's Email: [e-mail]

Goal

Today will be a tour of how to use SageMathCloud (SMC), which is the website for this class.

Background

• I launched SMC in April 2013 motivated by teaching this very class.

• 2014: taught this class again using it.

• 2015: went on sabbatical and worked on writing SMC fulltime for the year.

What is does now: collaboratively use popular open source math-related software in your browser

• SageMath: command line, run programs, use worksheets

• Python

• R

• Latex

• Jupyter notebooks

• Terminal

• Edit files and compile/run code (e.g., Java, C/C++, Fortran, etc.)

• Todo lists

• Chat rooms (for collaboration)

Also, course management

• So your teacher can use SMC in a course

Rest of today

Tutorial -- I'll do stuff; you should do something similar on your laptop

Things to do:

• Create a folder named scratch

• Add another student from the course to your project (settings --> add collab); you can remove them at any time.

• Create various types of files in that folder

  • A .txt file (type a little and inspect "TimeTravel")

  • A .md file

  • A .html file

  • A sage worksheet

  • A jupyter notebook

  • A todo list

  • A chatroom

  • a Terminal

  • A c program

  • A latex document

  • Upload a file from your computer (+New)

• Look at the "Log"

• Look at Backups

• Use Find to search in files

• Stop/Save/Restart your project (in project settings)
