Knowing nothing about UUID v4 generation, I have likely a stupid question. What makes you so confident that all implementations and their entropy sources are flawless enough to make actual collision probability close enough to theory?
- Thiez 3y agoWhat makes us so confident that our database implements ACID correctly, the RAM stores bins correctly, and the disk drivers store the data correctly? In the end we have to make some assumptions about the correctness of (some of the) components.
- tjoff 3y agoWe are not confident in any of that. Which is why we mitigate it with checksums, ECC etc. So depending on the consequences you might opt to reduce the risk or help mitigate the consequences. To just state that it is about as likely as my coffee maker being a portal to the future isn't very helpful. Poor entropy sources or bugs are not uncommon.
