Well I didn’t want to have a bio, but Lemmy doesn’t let me null it out, so I guess I’ll figure out something to put here later.

  • To be clear, you’re not going to find many displays that can reach 4,000 nits yet. A lot of HDR content actually is mastered for 1,000 nits and that’s considered kind of the target for the mid-high range OLEDs right now. My pretty much top of the line QD-OLED Samsung S95C maxes out at something like 1350 nits. A 1000 nit capable Steam Deck OLED has plenty of range in luminance for HDR to be effective there. And I’m sure it’s got pretty good color reproduction which is the other big aspect of HDR.

    One thing we haven’t talked about is the possibility that the Steam Deck is enhancing SDR content with dynamic tone mapping to such a degree that it’s difficult to tell the difference when you actually enable true HDR. I’d really have to see this with my own eyes to be able to say with more certainty what’s going on.












  • > Personally, I think it’d be nice if you could self-host just the bridge instances and connect them with beeper yourself, so that the part that isn’t e2e encrypted is running on software you can validate and hardware you control.

    I 100% agree this would be a great solution. That’s what I thought this page was going to be at first until I kept reading and realized it’s just a config guide for the Matrix Ansible setup. I wish they didn’t say “self host Beeper” on that page at all because self hosting Matrix has absolutely nothing to do with the Beeper service other than their devs built the bridges that they’re showing you how to set up with Matrix.






  • E2EE only exists up to the bridge, not the whole way to your client

    I just want to clarify that most bridges can be set up to have E2EE between the Matrix client and the bridge (regardless of whether the bridge supports encrypted chats on the bridged service because not all do, e.g. Facebook), but it is true that the bridge itself has to decrypt and translate between Matrix and the 3rd party chat service, so as you mentioned trusting who hosts bridges or doing it yourself is really important.


  • You can run headless or do what the person I was responding to recommended and put it behind an authenticated portal, but that’s not really going to stop other instances and clients from accessing the same resources that op is hoping to limit access to except in the most basic case of people casually browsing op’s Lemmy instance through op’s own lemmy-ui.

    Edit, but to be clear, what I was responding to and my response didn’t directly address op’s specific concern (which I kind of misunderstood myself before just now rereading) that outside/guest users shouldn’t be able to search for communities from other instances and I think it’s a fair concern because just searching for a community from another instance brings in posts and could be a vector for spam/abuse.


  • Wouldn’t this do basically nothing to prevent a 3rd party client from browsing your instance without authentication? I don’t know that there’s much that can really be done about this because you need open APIs for other instances to be able to access the content of your instance in order to make federation possible. That said, it’s an important consideration that anybody running a single person instance should consider. If you run a single person instance, people can learn a lot about you just by seeing which communities are available on your instance. The only way to obfuscate your actual interests is to have a dummy account subscribe to all the top communities on the biggest instances. (Which, honestly, this isn’t a bad strategy to employ anyway if you’re wanting a fresh All feed).
