  \frametitle{History of R project and Google Summer of Code}
  \begin{description}
  \item[1992] First \textbf{R} coded by Robert Gentleman and Ross
    Ihaka at University of Auckland, New Zealand.
  \item[1997] First Comprehensive R Archive Network (CRAN) web site
    hosting \textbf{R packages}.
  \item[1998] Google incorporated in Stanford, California.
  \item[2005] First \textbf{Google Summer of Code} (GSOC).
  \item[2008] First time R participates in GSOC (GSOC-R).
  \item[2012] My first year as co-administrator of GSOC-R.

  \frametitle{Google Summer of Code (GSOC)}
Student gets \$5500 for writing open source code for
    3 months.
    \begin{description}
    \item[Feb] \textbf{Admins} for open source organizations
      e.g. R, Debian, Wikimedia, Mozilla, apply to Google.
    \item[Mar] \textbf{Mentors} suggest projects for each org.\\
      \textbf{Students} submit project proposals to Google.\\
      Google gives funding for $n$ students to an org.
    \item[April] The top $n$ students get \$500 and begin coding.
    \item[July] Midterm evaluation, pass = \$2250.
    \item[Aug] Final evaluation, pass = \$2750.
    \item[November] Orgs get \$500/student mentored.
    \end{description}
  I have participated as an \textbf{admin} and \textbf{mentor} for the
  R project.

  \frametitle{What makes a good GSOC project?}
  Coding projects should:
  \begin{itemize}
  \item Result in free/open-source software.
  \item Be 3 months of full time work for a student.
  \item Include writing documentation and tests.
  \item Not include original research.
  \end{itemize}
  Examples: 
  \begin{itemize}
  \item Write a new R package.
  \item Improve an existing R package.
  \end{itemize}  
\end{frame}
