​Every year, thousands of hackathons take place all over the world. The "hackers" of these events unite and innovate in order to carry out a project or challenge in 24 to 72 hours. From these hackathons emerge several programs, ranging from personal assistants for deaf people to programs to detect cancer. These innovative and visionary projects, which were once only ideas, finally become reality in these hackathons thanks to the teamwork and the sharing of each other's knowledge.
