The branch part of the following is based on A Git Workflow for Agile Teams, which also contains lots of other useful links.

Creating a fork of the project you want to work on

For any project you want to work on you should create a fork in GitHub, by clicking on the 'Fork' button on the project you are interested in.

From now on we'll call the project you have forked from upstream and your own copy of that project on GitHub we'll call origin.

Creating a task

Check what's being used:

df -h

Find directories with lots of files in:

sudo find / -type d -size +100000c

Find large files:

Sometimes we get to a point where a Vagrant VM just won't run, and there's nothing for it but to get rid of it.

First get the ID of the machine in question:

cat .vagrant

Output will be something like:

{"active":{"hadoop_client":"31c1a009-f1b0-4acc-8200-1f33b95a0e3b"}}
