Even as an embedded C developer I use “idx” and “count” instead of “i”. Not just because I’m a member of the “slightly longer but more descriptive names are better” gang, but also for searchability. If I’m trying to track down where an array is accessed in a loop, for example, “idx” is more likely to take me only to the results I’m looking for and not also the “i” in int8_t or whatever.
Something that’d be significantly easier to do if it weren’t for the US’s continued immoral blockade and sanctions? Cuba does not have the resources to maintain the plant purely on their own, and they can’t hit a magic button that will suddenly let them find an abundance of spare tools and equipment to repair their infrastructure in a disaster scenario without wider access to international trade.
