I had email correspondence once with a vendor about how to talk to their i2c bus. The documentation was all asm, and I wanted to at least “uplift” to C. They didn’t have any answers, so I sent them my solution which was was the asm calls that the c stdlib decompiled into.

4 years later my company had bought a different company, who happened to be using a newer model of the same board. They asked me how we could use the 12c bus. “Well before you bought us, we emailed the vendor and sent back this C snippet”

It was my code, verbatim. I’ve always wondered how many times they passed that bit of code around.
