waaaah just sitting down to write masses of truly awful code to test a whole bunch of calculations... and then I remembered I could just dump it to text and record the results with 's 🥳 *kettle on feet up*

Just published a blog post on getting Playground Driven Development working with Carthage in Xcode. Wouldn't happen without 's solution. This fixes the `couldn't look up symbols` error that shows up in Xcode Playgrounds.

Yes you are absolutely correct. zip is basically applicative, though applicative has a different signature: F<A -> B> -> F<A> -> F<B> You can derive zip from the signature and vice-versa.

Turns out you can always define a zip-like function using just flatMap. So, if that's the case, does zip give us anything new that flatMap can't provide?? The answer is YES! Zip gives us a lot of things that flatMap alone cannot accomplish. Learn more:

When we set out to cover flatMap, we didn't expect it to take 5 episodes, but there was so much to cover! This week we conclude our discussion on flatMap, and start to explore some complex problems that are only tractable due to all of our hard work:

It took us over a year of episodes to say the “monad” word, and we only did it in the last 5 seconds of the episode. The word is not the important part, all of its properties are what is so important!

Topology Fact Feb 4
A knot and another knot may not be the same knot, though the knot group of the knot and the other knot's knot group differ not; BUT if the knot group of a knot is the knot group of the not knotted knot, the knot is not knotted. (Author unknown)

Same, Munkres is a very friendly text book to learn topology. Looks like he even has a free edition on his website as a PDF, and I have a copy if you wanna borrow sometime.

Which topology book? All of my favorite topology books have no prerequisites on calculus, though it depends on what you wanna get out of topology.

Hey John! Sorry for the delay in response. Both Stephen and I were out of town or traveling the past few days. I’ve refunded the $11.90 to your card, so you should see it in a few days. Sorry again for the delay, and we’ll look into why the site didn’t allow fixing this.
