\begin{frame}{Race Task}
    Free Flight Competitions for Hang gliding or Paragliding
\begin{itemize}
    \item A race task each day of a comp
    \item Like a yachting buoy race in the sky
    \item Game of tag each turnpoint\footnote{Turnpoint are vertical cylinders} and make goal
    \item Flown by gliding in straight lines and circling in lift
\end{itemize}
\end{frame}


\begin{frame}{Rules}
The GAP rules were originally devised by \textbf{G}erolf Heinrichs, \textbf{A}ngelo Crapanzano and \textbf{P}aul Mollison.
\[ Total = DistancePoints + TimePoints + LeadingPoints + ArrivalPoints \]
    
\begin{itemize}
    \item CIVL\footnote{Commission Internationale de Vol Libre} makes the rules
    \item scorers apply the rules
    \item pilots contest the rules
\end{itemize}

\begin{frame}{Why Flare Timing?}
FS, the official scoring program, is a tangled spaghetti of data access, scoring math and user interface.
\begin{itemize}
    \item Only the scoring math
    \item Show more of the working
    \item Verify that scores match the spec', the GAP rules
    \item Compare computed results
\end{itemize}
\end{frame}

\begin{frame}{Why Haskell?}
\begin{itemize}
    \item Sum types and exhaustive pattern matching
    \item Property testing with \texttt{quickcheck}
    \item Units of measure with \texttt{uom-plugin}
    \item Compare floating point and rational math
    \item Package \texttt{fgl} for shortest path
    \item Parser combinators for file format parsing
\end{itemize}
