The workshop will take place at [[https://www.mpim-bonn.mpg.de/|Max-Planck Institut for Mathematics in Bonn, Gernany]]. Following a [[https://wiki.sagemath.org/Workshops|long tradition of similar workshops]], the Sage days 100 workshop will take place in Bonn Germany, Mon 22 July 2019 - Sat 27 July 2019. It welcomes anyone who wishes to work with !SageMath, from complete beginners to advanced developers. It will consist of tutorials, participant presentations and mostly free time to let participants work on their mathematical programming projects and get helped from more advanced users. The precise schedule of the workshop will be decided at the start of the workshop and adapted according to the participants' needs.
