    Anyway, what I wanted to know is why do people self host?

    For the warm and fuzzy feeling I get when I know all my documents, notes, calendars, contacts, passwords, movies/shows/music, videos, pictures and much more are stored safely in my basement and belong to me.

    Nobody is training their AI on it, nobody is trying to use them for targetted ads, nobody is selling them. Just for me.



  • Most modern OLED panels on TVs and monitors don’t actually use classic PWM for dimming, they never turn off completely and instead fluctuate between like 100% and 95% brightness based on the refresh rate.

    Did you ever test if you can see that as well at different refresh rates?

    rtings always tests this under “Image Flicker”. https://www.rtings.com/monitor/tests/motion/image-flicker

    It’s not considered flicker-free but the OLED panels listed with 0 Hz PWM frequency (most of them) should look fine.

    However, there are two other elements that might cause issues:

    • VRR flicker
    • ABL dimming in HDR

    Both can cause an unpleasant experience if you are sensitive to it.

    Phones still commonly use PWM because it uses less energy. There are some that have a DC dimming option but it’s rare.





  • Copying from an older comment of mine:

    IPv6 is pretty much identical to IPv4 in terms of functionality.

    The biggest difference is that there is no more need for NAT with IPv6 because of the sheer amount of IPv6 addresses available. Every device in an IPv6 network gets their own public IP.

    For example: I get 1 public IPv4 address from my ISP but 4,722,366,482,869,645,213,696 IPv6 addresses. That’s a number I can’t even pronounce and it’s just for me.

    There are a few advantages that this brings:

    • Any client in the network can get a fresh IP every day to reduce tracking
    • It is pretty much impossible to run a full network scan on this amount of IP addresses
    • Every device can expose their own service on their own IP (For example: You can run multiple web servers on the same port without a reverse proxy or multiple people can host their own game server on the same port)

    There are some more smaller changes that improve performance compared to IPv4, but it’s minimal.

    My unifi kit can convert us to IPv6 but I’m hesitant without knowing what devices it will break.

    You don’t usually “convert” to IPv6 but run in dual stack, with both IPv4 and IPv6 working simultaneously. Make sure your ISP supports IPv6 first, there is little use to only run IPv6 internally.
