Check out my new class on the C programming language!

69.84 C$ /h

C is the most important programming language of the last 50 years. This course is aimed both at absolute beginners and at amateur programmers who wish to become proficient in C. I follow Kernighan and Ritchie's book but I elaborate on the fundamental concepts that underlie the development and runtime environments, e.g. how the compiler works, what the stack is, etc.

- Security: I teach you how to recognize the pitfalls of the web and how to protect your personal data.

Concrete examples of what we can do together:

Online procedures: connect to official websites (Ameli, Taxes, CAF) with complete peace of mind.

Social connection: learn how to use emails, video calls (WhatsApp, Skype) or share photos with your family.

Security: managing your passwords and browsing the internet without fear.
