@youvegotmail9385 Год назад

Couldn't agree more. Content creators forget that their viewers are noobs, so they need to slow the fuck down and be extremely clear when presenting. lol.

@TheChef1984 Год назад

This was a perfect level of depth for me as a delivery manager trying to increase my technical knowledge. The examples were the key. The analogy’s I’ve seen elsewhere are helpful to a point, but seeing you literally put a URL into a browser with the relevant inputs and then seeing the structured response come back was the light bulb moment.

@RoryDavidWatts 3 года назад

A note on your sound (in case it helps) - the volume of your speech fluctuates, and I think it's a mixing problem. My best guess is you have a compressor with a long release. There seem to be periods where the volume is normal, then they get pulled down for a little while, before raising back to normal. This can be slightly distracting once you notice it. Just to point it out. I thought it was a wonderful video, and you're doing a great job! Thanks

Hi @CodeWithChris, the lucid description is off course highly appreciable and helps all learn the topic in an interesting way.

"Hello, if your blog was created with the help from a website then you can try checking documentation to see how to get your ""feeds"", the API of your blog is basically a JSON version of your website, you can either contact support if you don't know or ask some website experts, or maybe ask the developer if he knows - Francis"
