  • Back-up/failover instances for communities and users.

    Every user and every admin of a community should be able to assign a failover instance in case the main instance goes down temporarily or permanently. All relevant data (posts, upvotes, settings, password hashes, mod log) would be permanently syched so you could just switch over in case of a downtime and most importantly, no content would be lost.

    If you implement a feature to set the failover instance as your new main instance, that would also implicitly allow you to migrate users and communities elsewhere.

    I go for option 1.

    In all programming languages that I know, integers have a maximum number. E.g., in C that’d be 2,147,483,647. After that, you would run into an overflow, resulting in either…

    • a crash (train stops, no more deaths),
    • death count suddenly turns negative (all people previously killed are suddenly alive again and even new people are generated out of nowhere) - until we reach the next overflow when people disappear and start dying again
    • or - if it’s an unsigned integer - death count resets everytime we reach the maximum limit

    So compared to option 2, we have a chance of stopping the death count. And even if the train keeps running, we have essentially option 2 but the same people only die very rarely. If we assume a cycle of 1 death per second and an integer boundary of 2,147,483,647, that’s just one death every 68 years per person involved. Seems more fair to me compared to 100 people constantly dying over and over again.


  • If we say that the SSN database internally only stores numbers today, but could also store hexadecimal values without significant redesigns, I would assume that SSNs are stored as text already. So no matter if you put numbers, hex or text, 9 places will always use 9 bytes (assuming it’s ASCII only and doesn’t support UTF-8 etc.).

    Furthermore, the post implied that the current technical limit is 999,999,999. That very much sounds like a character data type to me. Otherwise, the limit is usually something like 2^x.

    If SSNs are stored as numbers today, then hex and text would lead to quite some change. If you go for a re-design, you can as well just increase the length of the field.






  • Is there a credible source for the costs of hosting? Wikipedia is listing similar ad revenues as you did but no info on the costs. YouTube has 2.7 billion users that watch in average around 11 hours of videos a month. If 2 billion USD/y would be sufficient to host all that that’d be just 0,74 USD/user*year or 0,06 USD per month. That sounds really cheap considering that you have to pay for storage, traffic, backups and redundancies (at least I never heard of significant outages or data loss on YT).

    Does anyone have a credible source on the number of employees YouTube has? If you search for that you fine vastly different number from just 2k to 189k employees.


  • TBH I’m not sure if a platform like YouTube will ever exist in a non-commercial way. Many creators that I follow reached a level of professionalism that comes with significant costs. You need expensive cameras, microphones, lights, high-end computers, drones, personnel costs for cutters and people that help with research. They have travel costs, sometimes rent for offices etc. All that just to produce the content.

    On top, there are significant costs for hosting. I mean YouTube is hosted on multiple data centers rather than a bunch of servers or even home computers. Already Lemmy, which is mostly text and pictures, is a decent financial burden to instance owners. Not to mention the time for moderation and administration. And even here, in a place full of hardcore FOSS supporters, it’s not like admins are drowned in donations.

    If YouTube ads and product placements are the only source of income for content creators, then the only alternative would be that consumers directly pay for the content and the platform. Or that such a platform would be paid by some state / taxes. Both of which don’t sound very realistic to me.
