Coding is big part of our work Code is in the heart of research : Controlling instruments. Handling, exploring, processing data. Creating graphs and visualizations. 1stECARS Summer school, 30thMay 2016, Bucharest, Romania
And bad code can be really bad Mars climate orbiter, NASA Cost: $193 million Last contact: 23 September 1999 Reason: The peer review preliminary findings indicate that one team used English units (e.g., inches, feet and pounds) while the other used metric units for a key spacecraft operation. 1stECARS Summer school, 30thMay 2016, Bucharest, Romania
more than once! Hitomi Xray telescope, JAXA/NASA Cost: $370 million Last contact: 28 March 2016 Reason: But because the wrong command had been uploaded, the firing caused the spacecraft to accelerate further. The improper command had been uploaded to the satellite weeks earlier without proper testing; JAXA says that it is investigating what happened. 1st ECARS Summer school, 30th May 2016, Bucharest, Romania

Our problems are not new Programmers have met these problems again and again. They can teach us good coding style, advanced programming concepts, but also time management, team interactions and learning practices. (but don t hire a university graduate to learn these...) 1st ECARS Summer school, 30th May 2016, Bucharest, Romania
Why python Python is a high-level programming language: 1. Easy 2. Batteries included 3. Great community 4. General purpose 5. Cross-platform 6. Free 1st ECARS Summer school, 30th May 2016, Bucharest, Romania
For scientific programming Fast arrays and matrices Plots and graphs A lot of libraries and features e.g machine learning, image processing... Syntax similar to MatLab 1st ECARS Summer school, 30th May 2016, Bucharest, Romania
