Courses
Introduction to programming
This course presents the fundamentals of programming and object-oriented programming (using the Java language). It also gives an introduction to a computer development environment (by default on Linux).
Information, Computation, Communication
On one side, this course covers the concepts of algorithms, the representation of information, signal sampling and compression, and an overview of systems (CPU, memory, etc.). On the other side, an introduction to programming in Python is given.
