The ending was hilarious. I'm glad they didn't cut it out.

I love how the students ask all the right questions.

Makes sense David is with Harvard.
So concise... I am watching for entertainment but for those new to development I suggest that you hang on his every word. So much information tucked into every paragraph

David is amazing at giving these lectures. If he joined NYU where Daniel Shiffman and Ken Perlin are, that would be the best university in the world.

The geolocation script at the end has a bug. If the script doesn't get the right precision argument (or has other errors) it defaults to nearest thing it can figure out – in this case the country it's in. So it puts the lat/long in the middle of the USA as a default. So that's why it points to Kansas. There's lots of stories about the unfortunate people who happened to live on the farm at that default being accused of all kinds of crimes because stupid investigators thought they knew how to geolocate an IP address.

Too bad he didn't mention that back in the day we used <table> and stitched together images to create graphical layouts for websites :)

I liked it better in the previous lessons when David used the cs50 IDE in Darkmode so I could watch this at night without destroying my eyes. Joke aside I think these are amazing, the only explanation you'll ever need on programming, html, python etc.
