This is the repo for homework 1, the generation of a seemingly random data set.
This is the README file for homework #1. Everyone is going to create a fork of this repository and create a directory whose name is <yourname> where your last name is separated from your first with an underscore "_". Once you have done this copy the tab separated values file (tsv) with your data to the file and send me a pull request from your master to add it to the repo. If you have a team that consists of more than the person who has uploaded the file, please include a second file called team.csv with the names of your team.
I will add tutorials over the next few days.
After you set up the github account and email me. You will get a github invite. Accept that invitation. The next thing you should do is fork the repository. That means that you create your own copy of the repository in your github account.
You don't edit anything on github. Github stores your backup. In order to edit your repo you have to copy it to your machine. This requires you to download git to your local machine. There are several ways to do this.
You just need to go this link:
http://git-scm.com/download/mac
Double click on the downloaded file and install in the usual way.

You documents are in /Users//Documents. In the terminal type:
cd Documents
To check where you are type:

This returns the present working directory.
Your Documents are in C:\Users\\Documents. In the terminal type:
cd Documents
Tell Git your name so your commits will be properly labeled. Type everything after the $ here:
git config --global user.name "Your Name"
Tell Git the email address that will be associated with your Git commits. The email you specify should be the same one you used to sign up for GitHub.
git config --global user.email "YOUR EMAIL ADDRESS"
Now go back to your browser and open up the repo that you forked. On the right side of the page near the top, there is a box under settings. In that box is the URL of your fork. Here is a picture.
Now that you know what you are looking for. Copy it and clone it by typing:
git clone [email protected]:<your_github_username>/homework1.git
Now you have your own copy of the repo both on your machine and in your github account. You can look at any of the files.
You actually have a copy of the master on your machine. When you add something for the first time, you should not add to the master you should make changes to your own branch. Usually the branch name is the topic. In this case use your first name. Type:
git branch <first_name>
We can see all of the branches by typing:
git branch
The star means that we are still on the master branch.
To switch branches type:
git checkout <first_name>
Create a directory with your first and last name from the command line:
mkdir <firstName_LastName>
You can use the command line or a gui to copy your assignment into the directory you just created. If you are on a team with more than one person, please include a file with all of your team.
To add your homework to your branch. You will do this by adding all files in the directory to your branch by typing:
git add .
You should save or commit your changes with a message. Type the following:
git commit -m "added my homework."
or type:
git commit -m "added my homework and team."
To update your copy on github you have to push your changes. This only did the merge on the local side.
Git does not automatically know where you want to pull from. To see where git is pulling from, type:
git remote -v
The "-v" is a common command line flag for verbose. Because you forked both the (fetch) where you pull from and where you push to (push) are the same. Now specify a new upstream repository that will be synced by the fork.
git remote add upstream git://github.com/cuny-ml-f2014/homework1.git
To see everyone's accepted changes to the master, you have to pull the upstream master. This requires a fetch command. Make sure that you have commited your changes. Type:
git fetch upstream
you have now pulled the changes from my branch to your local machine. The next step is to merge it into your master branch.
git checkout master
and to incorporate the changes on your local master, type:
git merge upstream/master
You will want to save those to your github account as well. So to finish, type:
git push origin master
