+     \mbox{}\hfill we need to have *access* to the /software that governs our life/
+** Zoom on reproducibility
+*** Reproducibility (Wikipedia)
+    the ability of an entire experiment or study to be \emph{reproduced}\\
+    \hfill either by the researcher or \emph{by someone else working independently}.
+*** Why we want it
+    - foundation of the scientific method
+    - accelerator of research: allows to build upon previous work
+    - transparency of results eases acceptance
+    - reproducibility is \emph{the essence} of \emph{industry}!
+*** For an experiment involving software, we need
+   - open access :: to the scientific article describing it
+   - open data sets :: used in the experiment
+   - source code :: of all the components
+   # - environment :: of execution
+   # - stable references :: between all this
+
+* Software source code is essential
