Daniel Stenberg, developer of very popular opensource library/utility curl, once received a threatening email: https://daniel.haxx.se/blog/2021/02/19/i-will-slaughter-you/ https://daniel.haxx.se/blog/2021/02/19/i-will-slaughter-you/ SQLite developers were receiving phone calls in the middle of the night, so decided to change temporary files prefix: https://github.com/mackyle/sqlite/blob/3cf493d/src/os.h#L52-L66 https://github.com/mackyle/sqlite/blob/3cf493d/src/os.h#L52-...
