  INTRODUCTION

  Edit the general explanatory paragraph below if you want to change
  the pitch.
-->
<p>
  <a href="{{site.swc_site}}">Software Carpentry</a>'s mission
  is to help scientists and engineers get more research done in less
  time and with less pain by teaching them basic lab skills for
  scientific computing.  This hands-on workshop will cover basic
  concepts and tools, including program design, version control, data
  management, and task automation.  Participants will be encouraged to
  help one another and to apply what they have learned to their own
  research problems.

  SYLLABUS

  Show what topics will be covered.

  1. If your workshop is R rather than Python, remove the comment
     around that section and put a comment around the Python section.
  2. Some workshops will delete SQL.
  3. Please make sure the list of topics is synchronized with what you
     intend to teach.
  4. You may need to move the div's with class="col-md-6" around inside
     the div's with class="row" to balance the multi-column layout.

<h2 id="setup">Setup</h2>

<p>
  To participate in a Software Carpentry workshop, you will need
  access to the software described below. In addition, you will
  need an up-to-date web browser. We will be using a <a href="dundee-setup.html">university-provided
  desktop environment</a> but, if you would prefer to use your own laptop, 
  the following software should be installed prior to arrival at the 
  workshop.
</p>
<p>
  We maintain a list of common issues that occur during installation as a reference for instructors
  that may be useful on the
  <a href = "https://github.com/swcarpentry/workshop-template/wiki/Configuration-Problems-and-Solutions">Configuration Problems and Solutions wiki page</a>.

    Git is a version control system that lets you track who made changes
    to what when and has options for easily updating a shared or public
    version of your code
    on <a href="https://github.com/">github.com</a>. You will need a
    <a href="https://help.github.com/articles/supported-browsers/">supported</a>

        <a href="http://sourceforge.net/projects/git-osx-installer/files/">this list</a>.
        After installing Git, there will not be anything in your <code>/Applications</code> folder,
        as Git is a command line program.
        <strong>For older versions of OS X (10.5-10.8)</strong> use the

    When you're writing code, it's nice to have a text editor that is
    optimized for writing code, with features like automatic
    color-coding of key words.  The default text editor on Mac OS X and
    Linux is usually set to Vim, which is not famous for being
    intuitive.  if you accidentally find yourself stuck in it, try
    typing the escape key, followed by <code>:q!</code> (colon, lower-case 'q',
    exclamation mark), then hitting Return to return to the shell.

  <h3>Python</h3>

  <p>
    <a href="http://python.org">Python</a> is a popular language for
    scientific computing, and great for general-purpose programming as
    well.  Installing all of its scientific packages individually can be
    a bit difficult, so we recommend
    <a href="https://www.continuum.io/anaconda">Anaconda</a>,
    an all-in-one installer.
  </p>

    <p>
      Regardless of how you choose to install it,
      <strong>please make sure you install Python version 3.x</strong>
      (e.g., 3.4 is fine).
    </p>

    <p>
      We will teach Python using the IPython notebook, a programming environment
      that runs in a web browser. For this to work you will need a reasonably
      up-to-date browser. The current versions of the Chrome, Safari and
      Firefox browsers are all <a
      href='http://ipython.org/ipython-doc/2/install/install.html#browser-compatibility'>supported</a>
      (some older browsers, including Internet Explorer version 9
      and below, are not).

  <h3>Virtual Machine</h3>

  <p>
    Some instructors prefer to have learners use a virtual machine (VM)
    rather than install software on their own computers.  If your
    instructors have chosen to do this, please:
  </p>
  <ol>
    <li>
      Install <a href="https://www.virtualbox.org/">VirtualBox</a>.
    </li>
    <li>
      Download our <a href="{{site.swc_vm}}">VM image</a>.
      <strong>Warning:</strong> this file is 1.7 GByte, so please
      download it <em>before</em> coming to your workshop.
    </li>
    <li>
      Load the VM into VirtualBox by selecting "Import Appliance" and
      loading the <code>.ova</code> file.
    </li>
  </ol>
