okay so like a month ago @trashpanda sent me one of those 'spycam finder' doodads that you see going for like 80-100 dollars online that supposedly 'find spy cameras and gps trackers'.

Zuckerberg has blown 77 billion – enough money to revitalize entire countries – on an idea so overwhelmingly, obviously stupid that I have never once heard anyone, from the Thanksgiving avuncular table to the most wretched depths of social media, say they liked it or even tried it.

Day 7 of Advent of Compiler Optimisations!
Converting numbers to ASCII requires dividing by 10 repeatedly. But division is slow, so what does the compiler actually generate? Turns out: no division instructions at all! Instead, a mysterious constant (0xcccccccd) appears along with multiply and shift operations. How does this produce exact results for all inputs?
