  • Yeah, that’s fair enough, though I’m not sure it’s very different from malicious instances creating normal user accounts?

    You can see when users from an instance are all suspiciously voting the same way at the same time regardless of whether they are usernames or IDs.

    There’s lots of legitimate users that only vote but never post so doing it based on that doesn’t seem very effective?

    The second problem is solved using public key cryptography, the same way that you can’t impersonate someone else’s username to post comments. Votes and comments are digitally signed (There would need to be a different public key for voting to maintain pseudonymity though).


  • How about pseudonymous as a compromise? Votes could be publicly federated but tied to some uuid instead of the username. That way you still have the same anti spam ability (can see that a user upvoted these things from this instance at this time) but can’t tie it directly to comments or actual user accounts without some extra osint.

    It might be theoretically possible to correlate the uuids with an account’s activity and dox the user in some cases, especially with some instances having a single user, but it would be very difficult or impossible to do on larger instances and would add an extra layer. Single user instances would be kind of impossible to make totally private anyway because they can be identified by instance.




  • I’d add to this to say that redis as a key-value store often sits alongside a relational database like postgres etc. to act as a cache for it.

    Basically, requests to be sent to the relational db (like postgres) get turned into a key and the results stored as a value in redis. Then when the same request comes through again, it can pull the results quickly out of the key-value store without having to search postgres by running a long SQL query again. There’s a few different caching strategies to keep things up to date or have the cached data expire regularly, etc. but that’s the gist of it.

    Important to note that not all applications need something like that and not all queries would even benefit from it (postgres is pretty fast and can even do that kind of thing itself) but if there’s a lot of users running the same slow query over and over, caching the results can help immensely.







  • It’s not that it’s on the 172.16.0.0/12 range. That’s totally normal and used for all kinds of stuff.

    It’s that it’s in 172.16.42.0/24 which is the default dhcp settings for a wifi pineapple. It’s the /24 mask given on the .42 that’s a little suspicious because that’s not a common range for anything else.

    Being assigned one of those specific 253 hosts with that subnet mask would definitely make me think twice.



  • It sounds like they controlled for that and did a bunch of different statistical models to break it down by different demographics and economics. That said, I’m finding it hard to find the original paper. It’s not linked to in the article or any of the AP versions I found. Nature has a link to Google scholar but that comes up with nothing and it’s not referenced in the researcher’s publications on the Oxford site yet. Maybe it went to the press already but the actual article isn’t out yet?

    It does sound very broad though and difficult/impossible to draw any causation. Still interesting through as it does kinda show that any negative causative link that might exist between well-being and internet use is not strong enough to outweigh other positive factors that are correlated with it (even non-causative ones).

    But what volume would it be? Is it a small amount of glitter or a lot? What’s the g/cm³ of glitter? What about tiny bits of uranium? I feel like all the little bits of air between the glitter particles would lower the density compared with just a solid block of uranium which would increase the volume but…

    I feel like someone should put some numbers in this thread.

    I was going to come up with something fun and clever to keep it going but the next line of the real song starts with “cream-coloured ponies” so I think we should probably just leave it here after all.

    There are some of the internet’s things that we don’t need to enumerate.
