Show HN: MacOS Live Screensaver – A screensaver that plays live video streams

I was gonna warn you about a bug in macOS 15+ where your screensaver stays around after you go back to the desktop, but for some reason your code seems to avoid that issue. I'm not quite sure how, as you don't hook stopAnimation or any event apart from the deinit. But it works, so, massive kudos, I'll have to try and understand why !
look at the animateoneframe function, there's the workaround
FYI that works 99% of the time, but for some people it sometimes crashes (because we exit our host container - legacyScreenSaver.appex - and sometimes if you do it at a wrong time things just hang).
You check if the screen is locked, and if not, kill the host. But screen is not locked in System Settings. So basically, you're killing the host process every 2 seconds (and macOS, at least in Tahoe, restarts it, it doesn't in previous macOS versions).
That's also what causes your issues with "Options" not working (because you killed the instance that was linked to that button). The way we workaround it usually is to hook a system event.

Look for handleWillStopNotification and com.apple.screensaver.willstop
Something I've wondered - but not had much empirical evidence for - is if entirely vibe-coded projects are difficult to maintain. I, too, don't know swift so I cannot look over the codebase to gauge this. I am curious if any swift savants out there can weigh in.
Furthermore, I will follow the project and keep an eye out for patches/discussions and try to discern any friction and/or loss in momentum because it is difficult to work with (e.g. more bug/feature tickets than PRs, etc.). I am aware it might fizzle out on its own, irrespective of the quality of the codebase. This will be a curious exercise for me. This may be my first empirical data on this topic - sadly on vibe-coded & maintainability, not the project itself.
However this project is so simple it's more akin to a script. Really not that hard to grasp despite not knowing swift.
Also vibe coded an android tv version and used this codebase as input ;)
My supposition is that the better documented a language, the easier it would be for the LLMs.
Or is it the opposite: The more obtuse a language, the more StackOverflow questions, the easier it is for LLMs to work with.
Vibe coding is too “Hail Mary” to me, but if you’re into it, I would think the best way to do that is by giving a LLM the git history of the project with each commit contain the prompt that created it and, if a human tweaked things, requiring that human to provide a good commit comment.
Then, you could give a LLM the git repo, instructions on what change you want to see, and have it create the next commit.
Is this enough? Personally, I have a what very well may be a bad habit of mine that doesn't necessarily check git commit messages. When I'm working in a code base, I just never think about scrolling through those hoping to find where this bit of code was changed. I'd much rather have comments in the code itself. It seems better to me to save the maintainer time and effort. Maybe I've just taken too seriously the idea of "assume the maintainer after you will be a serial killer that knows where you live. don't make them angry by being lazy"

for me it's working on a thing, and then linting, type checking, running tests. and even then thoughtfulness still required
Excellent, advertising-free live streams to choose from here:

I often turn on the kelp forest (sound muted) as a pleasing backdrop on my living room TV, but they're all pretty neat.
idk if any of y'all ever used https://satelliteeyes.tomtaylor.co.uk/ but I was a big fan. such that i now have my own process of keeping my wallpaper updated w/ various city webcams. throw in some noise/desaturation and you've got an _aesthetic_
anyway, this is about a screensaver not a wallpaper and i think there is cool potential with video streams as screensavers
Also, from a time long ago in a galaxy far away where we had production CRTs that were color calibrated, we would not turn them off either. They had a saver mode as well by running a not quite black signal to them, but not enough to burn in phosphors. It was even meant to "even" out some of them.
So because I'm that old that has used CRTs for such a long part of my life, screen savers will always be just part of the routine.
