+There and Back Again, Reproducibly!
+SCALE 18x, Pasadena, California
+2020-03-08 16:30 to 17:30
+Room 106
+
+There is an epic journey from reviewed source code to the code you
+actually run on your computer, and things can go quietly wrong along
+the way!
+
+We can't do absolutely everything ourselves by hand, so we necessarily
+put trust into something or someone along the way. Will you join us on
+our journey, brave adventurer?
+
+What happens to your code as it passes through dark forests,
+trecherous mountain passes, or deep forboding caverns? What if
+something is quietly corrupting an otherwise trustworthy ally? Help
+showing up, but with it's own motives?
+
+Reproducible Builds gives a project confidence that the journey from
+source code to binary code gets you there and back again.
