When it is your week to submit the "official" homework solutions, you must use the LaTeX document preparation system. If you don't already know how to use LaTeX, there is plenty of online documentation to help you get started, but please feel free to ask me if you need help! At the bottom of this page are some links to LaTeX resources.
Overview
We will use Git and GitHub to manage the homework files for this class. Here is a rough overview of what you will do when it is your turn to submit official solutions (more details below):
First you will download our Math700Homework Git repository to your hard drive. Then you will type your solutions in the tex/Homework*.tex file corresponding to the assignment for which you are responsible. You will commit your changes to your local version of our repository. Finally, on the assignment due date, you will sync your version of our repository with the online version.
If you are new to Git, check out the 5 Easy Guides to Help You Get Started. In particular, the 15 minute Git tutorial, the git--the simple guide, and the GitHub help pages are excellent. For detailed comprehensive documentation see http://git-scm.com/doc.
Details
-
First, tell me your GitHub username so I can add you as a collaborator on the Math700Homework project.
-
Next, install Git on your computer.
-
If you are using a Mac or Linux, upload a public ssh key to your GitHub account. (If you are using GitHub for Windows you can skip this step.)
-
Once I add you as a collaborator, you can clone the Math700Homework repository to your computer's hard drive. How you do this may depend on your operating system.
-
Linux. Invoke the following at the command line:
mkdir -p ~/git cd ~/git git clone [email protected]:williamdemeo/Math700Homework.gitthe same commands should work on a Mac in a terminal window. See also the first Tip below.
-
Windows. I have never used the GitHub for Windows app, so I don't know how to clone a repo in Windows. However, according to this help.github.com page, it's easy. If you have problems, please consult http://windows.github.com/help.html
-
-
Next, make some changes to the files in the repository. For example, you might edit the file Homework01.tex in the Math700Homework/tex directory.
-
Commit your changes to your local version of the repository:
git add Homework01.tex git commit -m "added a sentence to make the proof clearer"(In quotes is your comment explaining, if possible, why the changes were made.)
-
On the due date of the assignment for which you're responsible, push your changes to the remote GitHub repository:
git push origin masterIf you get errors, please let me know!
As soon as you push your changes to GitHub, they will be viewable by everyone. In order to give other students a chance to solve the problems on their own, please wait until the due date of the assignment to push your solutions.
-
If you've set up Git and your GitHub account properly, you won't have to enter your GitHub password every time you push changes to the repository. If you use a Mac or Linux, you should upload your public ssh key to your GitHub account by following these instructions. In Windows, this should work automatically if you use the native GitHub app.
-
If you're a fan of Emacs, you might want to install the Emacs package called Magit, which enables you to commit and push without leaving the Emacs editor--very convenient! (Magit cheatsheet)
-
This page on recording changes to the repository is extremely informative. There is a lot of information on that page. If you're new to version controlling, don't be scared, we'll only need the very basics.
-
Optimally, your commit comments should indicate why changes were made, and not what was changed. Git keeps a perfect record of what was changed, so comments mentioning this are somewhat redundant (although they can sometimes be helpful). Instead, try to give some justification of the changes. This is often hard to do in just a few lines and without spending too long thinking about each commit, so don't worry too much; just keep it in the back of your mind.

If you ever have any trouble using Git or GitHub, please let me know! You can email me or create a new wiki page for discussing Git, or open a new issue.
