Voor middelbare scholieren die willen leren programmeren. | |
- Data: **7 t/m 11 juli** | |
- Tijd: **13.00 - 16.00 uur** | |
Als je meedoet, leer je in vijf dagen de beginselen van programmeren — de computer laten doen wat je wilt. Je hebt geen programmeerervaring nodig. | |
Je gaat algoritmes schrijven om priemgetallen te vinden, versleutelde teksten kraken en meer. Na de cursus heb je genoeg geleerd om zelfstandig verder te leren: [web design](http://rubyprog.nl/sinatra/hoofdstuk1), games maken; noem maar op. | |
We gebruiken Ruby, een uitstekende eerste programmeertaal. [Doe een oefenles](http://rubyprog.nl/ruby/hoofdstuk1). |

% of the form | |

% We assess the fitness of the data collapse by interpolating the data points of one set, and calculating the mean | |
% squared error (mse) with the points of the other data sets in the overlapping region. | |
% We repeat this for all sets. (See Bhattacharjee 2001) | |
