Occasionally I'll go to a subreddit on mobile browser and half the time I can't view it due to mature content. If I really care then I'll go to old.reddit but often I'll just back out.
I find them super useful when screen sharing in a meeting because you can just share the secondary display and all your other crap (and notifications!) can stay on the main display.
There's even some things you can do with a self-hosted media server that you just can't easily do with sreaaming services. For example, Jellyfin has a group sync feature where multiple users can join a group and when someone plays something, it plays for everyone. It works great for watching shows with friends remotely. I think Amazon Prime video has something like this but none of the others IIRC.
It doesn't have to be that expensive if you keep it modest though. I have an old Dell Optiplex (I think from 2012?) that I run a fair amount of stuff on. Things like Jellyfin (with Sonarr/Radarr/etc), a finance tracking web app, Home Assistant, a wiki, and some other miscellaneous stuff. I don't have a ton of storage though. Currently just the 512gb SSD that the OS is on. I have a couple 8TB HDDs that I want to get setup but they're a little loud for being in my bedroom.
The big thing I notice is that it can really struggle to encode media if it's not in the right format. It doesn't have much of a GPU though so that doesn't help. And more modern hardware would be much better too, but this is fine for my needs at the moment.
These CAPTCHAs do more than just check if you clicked the right pictures. They analyze your mouse movements and stuff. For example, a bot would move the mouse in perfectly straight lines, click all the pictures quickly, etc. But a human would have more natural movements.
I hear people say "program in assembler" but IMO that's wrong. I'd say you write the code in "assembly language" (or better yet, the actual architecture you're using like "x86 assembly") but you "assemble" it with an "assembler". Kind of like how you could write a program in the "C language" and "compile" it with a "compiler"
I haven't had the same experience with DuckDNS. It was great for a few years, but for about the past year it would randomly go down (preventing access) or my domain would get flagged as spam. I ended up buying my own domain from cloudflare but I'm planning on investigating Tailscale at some point.
Yeah, I have a Nest Mini that randomly died and is now just sitting in a box. This might be the perfect project, assuming whatever's broken would get swapped out.
But that doesn't do anything to mitigate using the same password/phrase on multiple services.
