  • Essentially for something to be decentralised and not ephemeral, everyone needs a copy of the data.

    To go into a bit more detail—one of the biggest benefits of decentralised systems is generally redundancy has to be built in otherwise you have a Single Point Of Failure™️, and then you get data loss when it’s gone. Given any sensible decentralised system is designed to avoid this scenario, that data has to be somewhere, and generally the simplest and less expensive (in terms of processing) way to improve on data in one place, is to have it in every place. Any time the data isn’t in one place or every place, you then have an exercise in figuring out where it actually is. This “finding it” processing is going to take time and effort, and if you imagine a standard semi-popular lemmy post, that’s potentially data coming from all sorts of different places, which may or may not be there—this would inevitably make request times ridiculous and basically no one would use it.

    At the end of the day, any kind of processing is energy, cost & time expensive, whereas storage makes that part of the process effectively instant and is much cheaper than increasing processing power in both cost and energy.

    So basically in this use case and many like it: it makes sense if you’re trying to pick what to optimise, you optimise for lower processing and higher storage requirements rather than vice versa.

    The history aspect is more straightforward to understand given the above, if you expect people to care what happened a year ago and want to support that, that data needs to live somewhere






  • From your link

    Any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person[15]

    The “directly or indirectly” part is important here, a username is a constant identifier between a user’s posts and comments

    Given comments and posts are free text input, there’s no way of knowing the entire set of a user’s content doesn’t contain PII, unless an admin wants to spend the time combing through and determining which posts definitely contain PII and which definitely don’t, they should delete it all. The data subject does not need to make specific listings of what they want deleted, the onus is on the service owner to be able to process the deletion request completely and within a timely manner.



  • Was gonna say, I’m sat on 2.2k comments apparently in about 15 months, which is surprising to me given I probably only comment on about half the days in any given week.

    I will say compared to Reddit though, I tend to be more likely to comment here because there’re fewer people here and I want it to feel active enough for more people to continue joining (either lemmy in general, or just on smaller communities that don’t have a lot of activity yet).





  • I specifically don’t comment on people that give off the vibe they might be one of those kind of nutjobs, precisely because it gives them a notification with my username attached if I do. I’m on this site to kill some time with low effort, I want to minimise the risk of attracting the attention of some weirdo.

    I downvote in those scenarios and then report if appropriate. If enough other users feel the same way the comment goes down to the bottom of the thread and fewer users see it. Especially if it’s something that a mod eventually removes, as it reduces the reach until a mod can get to it.

    If I risk retaliation for doing that, I (and others) will just stop, meaning those comments stay up front & centre and we lose that soft moderation plus that engagement in general. Going into the comments will just end up being a worse experience







  • Hardware transcoding on SBCs is generally not fantastic, you’re gonna want to look for one that has VAAPI/VDPAU support or you’re gonna be looking at 100% CPU for half a day to transcode a film, which will make your other services effectively unavailable at the time.

    I used to run my Plex server on a Pi4 with 4GB of ram and it basically crashed any time transcoding kicked in, I swapped to an intel NUC so I could get QuickSync for transcoding.

    I’ll point out though, every SBC you’ve listed has usb, which is all you need for an external disk. If you’re worried about size, I’ve got a 5tb external drive that’s about 5cm², which is basically the footprint of any SBC you could use in this scenario
