[Cialug] Starting two jobs at once

[Matthew Nuzum]

Thanks for the reply. One of my goals is to make it easy for new contributors to get started. Right now, they just need a few common development tools. In this case, Make and Python.

Two things have come to mind, but I haven't tried them and I think they're both flawed:

1.
Start a task and background it with &
Start the foreground task and wait until it completes
Kill the background task

The prob is I'm not sure really how to kill a background task once it's in the background

2.
Use tmux or screen
This adds an extra dependency and it also makes using it a little harder for people. For example, some of those I've collaborated with in the past, such as designers, are not very comfortable with the terminal. Ctrl+c to end it is easy, not sure you can do this with tmux/screen.

In the Python world another tool that is used is fabric, but I don't think it ads any flexibility in this regard over make.
