Votre discussion sur les contrôles m'a fait me rappeler d'un article que j'ai lu sur les processeurs et l'électronique dans l'espace qui sont affectés par les radiations.

Fucking interesting imo

The RHBD (radiation hardening by design) process enabled manufacturers to use a standard CMOS (Complementary metal–oxide–semiconductor) fabrication process. This way, space-grade processors could be manufactured in commercial foundries, bringing the prices down to a manageable level and enabling space mission designers to catch up a little to commercially available stuff. Radiation was dealt with by engineering ingenuity rather than the sheer physics of the material. "For example, Triple Modular Redundancy is one of the most popular ways to achieve increased radiation resistance of an otherwise standard chip,” Weigand explained. "Three identical copies of every single bit of information are stored in the memory at all times. In the reading stage, all three copies are read and the correct one is chosen by a majority voting.”
Fucking interesting imo
