  \item Originated Israel in the early 2000s\footnote{Meta: Really, it’s just to justify the pick for character encoding in lore, the real reason is that it is the most cumbersome and pointlessly stupid I could come up with} {\footnotesize(this will be relevant later)}
  \item Now used all across the globe

\begin{items}
\item Encodes Gramatical and Syntactic information
\item Has a fixed number of possible values
\item Describes a tree-like syntax
\end{items}

\slide{Data — Gramatical — Generic}
\begin{items}
  \item 
  \item The Generic pronoun is the gramatical
\end{items}

\slide{Data — Variable}

\slide{Data — Semantic}
\begin{items}
  \item Encodes a concept.
  \item Uses the Universal Decimal Classification to represent information\footnote{Meta: I didn’t want to have to arbitrarilly coin words for like a week}\footnote{Meta: Also I wanted something that could reasonably be encoded onto DTMF without feeling too arbitrary}:
  \begin{items}
  \item numerical values are enocded by their corresponding tones
  \item periods (which are only present in UDC to help readability) are dropped
  \item colons are encoded as {\tt C*}

\item parenthesis are encoded as {\tt A*} (opening) and {\tt A\#} (closing)
\item square brackets are encoded as {\tt B*} (opening) and {\tt B\#} (closing)
\item quotes are encoded as {\tt C\#}
\item dashes are encoded as {\tt D*}
\item equals are encoded as {\tt D\#}
\item pluses are encoded as {\tt \#}
\item References to variables are done by including the name of the variable in between {\tt *}
\item Non UDC notation is achieved by referencing a variable containing a string litteral. 
\end{items}
\item No dictionary is directly provided by me.
\item Abriged version of the UDC at {\tt https://ucdsummary.info}
\item A more complte version can be obtain from the consortium, or be conuslted at a library.
\end{items}

\slide{Data — String Litteral}
Raw text data
\begin{items}
\item Encoded as hexadecimal where {\tt *} stands for 0xE and {\tt\#} stands for 0xF
\item Follows the EBCDIC 803 codepage
\item If characters outside of EBCDIC 803, decompose, convert all characters to unicode in the form U+xxxxxxxx, then express that with EBCDIC 803 \footnotesize{(Yes, that means that most proper nouns take actual ages to emit)}

\section{Translation}
\begin{quote}
Hark! It was ruled by Agamashuya and His son Gu Sabah: Tian practices against the lesser side of the invisible origin of light, beset by cosmetic prohibitions of silence and restraint; for Ngu, a slave to creativity, shall make inspection and certification prior to confirmation of Najva Guns’ official status. Deny thine humanity: There are no politics in real life.
\end{quote}

\slide{Extra info about the translation}
\begin{items}
\item This translation will be delivered as if from a a speaker in Tekalau\footnote{Meta: Because that’s the place that had the shortest fully qualified phone numbers, but also because it lets me get away with having both 69 and 42 in the phone number.}
\item It will be delivered as if broadcast to the network\footnote{Meta: Again, to keep it short}
\item There might be  mistakes in the audio due to typos \footnote{Go check 10 tones per seconds for 3 minutes without perfect pitch}
