This is horrifying.
- Denvercoder9 4y agoCould you explain why?
- jw1224 4y agoA real-life UUID collision
- AzzieElbab 4y agoNot that terrifying when humans are involved… assuming competence
- dylan604 4y agoAssuming competence with humans involved is terrifying
- iworahipfaangs2 4y agoWhy?
- akmarinov 4y agoIt’s an identifier collision, they’re supposed to be unique. That’s what did SHA-1 in.
- mort96 4y agoSHA-1 is a hash function. What did it in is that there was found a way to make different strings hash to the same value. This is just someone accidentally re-using serial numbers, it's not a weakness in some algorithm.
- intrasight 4y agoWhat's really horrifying is this: "such an incident cannot be detected unless the boxes arrive at the same port at the same time" So they running this port with pencil and paper? No database? No sanity checks?
- xxpor 4y agoHow do you know this container isn't the same one you saw before? You need to have them at the same place at the same time to know they're the same container.
- intrasight 4y agoComputers with business logic. It can't be the same one if it travels faster than is possible. And anyway, if they were being tracked ...
- LeChuck 4y agoThe terminal doesn't always know the destination. Why would it? And anyway, intended destinations can change.
- fuzzfactor 4y agoSuppose you were the guy who goes around numbering containers to begin with. What are you going to use, a laptop or something? If it ran out of power without completing its process, upon reboot it might very well assign the same number to the next container. Even without a computer, you could have the day shift actually paint the number on the first container, but fail to finish the paperwork or it could get lost. Then the night shift comes along and uses the same number on the next container.
- throwaway0a5e 4y ago>So they running this port with pencil and paper? No database? No sanity checks? Or they simply don't run those queries until they need to. i.e. "we don't give a F unless there's a hiccup" The point isn't to track containers. The point is to get goods to where they need to be and when. Unless two of the same container shows up thereby causing a WTF moment there is no problem because there is no ambiguity in the container handling process and therefore they don't care.
- lowercase 4y agoNo it's not lmao
