The most convenient userscript for me is this one that automatically likes YouTube videos. It’s configurable to be able to: like the video after a specified watch percentage, ignore already disliked videos, only like videos from subscribed channels, and ignore livestreams. I like it enough that I’ve made a few pull requests to fix it when YouTube changes their UI.

When I have the time, I work on an in-progress local version to implement a few new features including: (1) Support for the YouTube shorts UI. (2) An option for a notification/toast to appear when the video has been liked. (3) An option to check the watch percentage continuously (mutation observer) instead of a user-defined poll rate which sometimes misses liking very short videos in playlists. Eventually I’d like to port something like this as a YouTube ReVanced patch.

Also watch the video on Team APS’s channel featuring Prof. They convert Yu-Gi-Oh cards into Magic cards.

I helped my parents sand their log walls just before Christmas. After we stain and seal the logs, they want to tear up their ugly grey carpet and install hardwood floors. The argument now is how dark they want the floors to be. Yours looks so good! I’m sending them your picture for reference. (They have Wheaten Terriers)

This is worded better than what I said. The second round isn’t 1/2 because the door you initially picked was 1/100.

I was stubborn about this for so long, and I’m still not entirely sure I understand it, but here is a perspective that made me doubt my belief.

Imagine the Monty Hall Problem, but with 100 doors and only one grand prize. You pick one; it obviously has a 1/100 chance of being a grand prize. Then Monty reveals 98 doors without grand prizes in them such that the only doors left are the one you chose and one that Monty left unopened. Monty obviously arranged for one of those two doors to have the grand prize behind it. The “choice to switch” is really just a second round of the game, but with a 1/2 chance of winning (wrong, your odds change only if you “participate” in round two).

If you stick with your door, you are relying on your initial 1/100 chance of winning. If you switch, you are getting the 1/2 odds of the “second round”.

Apparently with three doors, switching gives you a 2/3 chance of winning, but I don’t understand the math of how to get that answer and I wouldn’t be able to calculate the odds of the 100 door version. I just know intuitivey that switching is better.
