I put something together very similar to this, https://cmdchallenge.com that I like a bit better because it has console input. There is also a Christmas edition "12 days of shell" https://12days.cmdchallenge.com that is more like a learning progression. - Source: Hacker News / 8 months ago

Nice to see this posted on HN! A while back ago I used them for the design of a site a built https://cmdchallenge.com/ which gives it a nice feel of achievement badges without using standard unicode characters that may look different depending on the client. - Source: Hacker News / 9 months ago

I use Yout for music. Go to a youtube video, and change the URL from youtube.com to yout.com. There is a download limit of 3 songs per hour, but that can be avoided by using a VPN. Source: about 1 year ago

I use this one all the time https://yout.com/. Source: about 1 year ago

Https://yout.com/ I use that, but you can only download like 5 vids every few hours, so if you’re like mass downloading for some reason it might not be the best for you. Source: over 1 year ago

Just saying, if you download a song from youtube as an mp3 (I just use yout.com), you can upload it to your local files on spotify, and then add it to your playlists like any other song. Source: over 1 year ago

You can just put the url of one of the youtube videos into yout.com and download it as an mp3, and then look on your "local files" from spotify and add it to any playlist!! Source: over 1 year ago
