 ## Network

 * Peak wifi users: 7673, APs deployed: 179
 * But the network was sometime very shitty because of SSID spam for instance

 ## Science is broken
 
 * Generating random experient data and have significant results
 * Publication bias, only the significant results are published
 * Mostly subconscious. What can we do to prevent p-term hacking ?
     * Usually nothing is done
     * Replicating studies
     * Talk about failure
     * Decouple study and data gathering
     * Preregristration for publication (and later check that publication is in
       line with the methodology presented in registration) -> already the case
       in drug study
     * Create the protocol first then publish it before the experiment. Publish
       the result indenpendently of the outcome
     * Sharing (data, methods, code, ...)
 * Good results (or negative results) are often boring,
   less attractive to the press but closer to the truth
   -> TED Talk science VS Boring science ?
