    - inconsistencies
    - data corruption
    - fraud
    - non reproducible findings...
    (picture from Nature, Sep. 2015)
*** (Lack of) Security and Quality of Software
     - vulnerabilities and bugs in systems...
     - ... become critical with IoT
*** (Potential) Citizen empowerment
     \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
