  • Apps from outside the Play Store? No, because previously your phone had no reason to ask Google anything. You could always not sign in to Google and disable Play Protect and use F-Droid and Obtainium.

    But now, it needs to check developer signatures to know if it’s a verified developer, and it obviously can’t cache all of them as the size would be insane.

    And that in turn implies that your phone needs to reach out to Google and be like yo, is this app banned?

    That query gives them at minimum the IP of the user, the package name, and the time at which it happened.

    And thus they can effectively track anyone using say, privacy apps, making it that much riskier to use them in places where they’re not allowed.

    For your “safety”.



  • Arguably, if it was normal to sideload apps it wouldn’t be as much of a barrier to users, but they’ve been conditionned to think they need an app and the only place you can ever get them is the store.

    It’s a technical hurdle only because Apple decided they want to control everything, and same on Android because of Google’s ever increasing war on sideloading. You used to download an APK from the browser and it would go like “This is an app! Install?”, but now you have to go enable third party installation and all that, and now the whole Play Protect forcing developer validation coming up.





  • You can mostly backup everything but it’s impossible to make a perfect backup like the old days anymore because of the TEE. Flashing a new ROM will change the keys and permanently make the old data worthless. Stuff like Google Authenticator for example simply won’t backup even with a perfect bit copy.

    Apps will restore okay but many will be logged out and have lost their permissions and push notification registration with Google.




  • For all its flaws and mess, NFS is still pretty good and used in production.

    I still use NFS to file share to my VMs because it still significantly outperforms virtiofs, and obviously network is a local bridge so latency is non-existent.

    The thing with rsync is that it’s designed to quickly compute the least amount of data transfer to sync over a remote (possibly high latency) link. So when it comes to backups, it’s literally designed to do that easily.

    The only cool new alternative I can think of is, use btrfs or ZFS and btrfs/zfs send | ssh backup btrfs/zfs recv which is the most efficient and reliable way to backup, because the filesystem is aware of exactly what changed and can send exactly that set of changes. And obviously all special attributes are carried over, hardlinks, ACLs, SELinux contexts, etc.

    The problem with backups over any kind of network share is that if you’re gonna use rsync anyway, the latency will be horrible and take forever.

    Of course you can also mix multiple things: rsync laptop to server periodically, then mount the server’s backup directory locally so you can easily browse and access older stuff.



  • Technically it wasn’t really designed with megainstances in mind that swallows the entire fediverse.

    My instance has no problem whatsoever keeping up and storage is well under control. But we’re few here subscribed to a subset of available communities so my instance isn’t 90% filled with content I don’t care about and will never look at. Also reduces the moderation burden because it’s slow enough I can actually mostly see everything that comes through.

    Lemmy itself is also pretty inefficient in that regard, you can very much make software that pulls instead and backfill local cache as needed.

    Even my Reddit subscriptions would be pretty easy on my instance.

  • One thing to keep in mind is ActivityPub isn’t exactly made for social media in the sense most people use it nowadays. It’s intended to be more like RSS feeds: you’re support to subscribe to stuff like news sites and be able to bring it all into a content aggregator. Seen that way, its design makes a lot of sense.

    It kinda works well for public microblogging as well. It’s when you start involving moderation, voting, sharing, boosting that things get kinda weird.

    I’ll add some of my comments to that discussion.
