+If you need to download a list of YouTube videos and don't want to download the
+actual YouTube list (which `yt-dlp` supports), you can use the following method.

+```js

+document.querySelectorAll('#contents a.ytd-thumbnail.style-scope.ytd-thumbnail').forEach(el => console.log(el.href))

+
+Download and install https://github.com/yt-dlp/yt-dlp.

+```sh
+# This will download all videos in videos.txt.
+yt-dlp --batch-file videos.txt -N `nproc` -f webm

+
+Sometimes you want to push to multiple origins at once. This is useful if you
+have a mirror of your repository on another server. You can do this by adding
+multiple push urls to your git config. After this you can push to all origins
+at once by using `git push --all`. This is a shorthand for command above.
+
+```sh
+git config --global alias.pushall '!sh -c "git remote | xargs -L1 git push --all"'
