Ruby Conf 12 - Y Not- Adventures in Functional Programming by Jim Weirich

Reminds me a bit of the coolest talk I ever got to see in person: ▶ this video It’s a derivation of the Y combinator from ruby lambdas

If anyone wants this in a humorous 1 hour format, watch the legendary Jim Weirich (rip) explain it here: ▶ this video Don't be discouraged that it is in Ruby as the concepts are completely general. Great watch even though I never coded a line of Ruby.

On the same topic, Jim Weirich's 2012 talk "Y Not - Adventures in Functional Programming" on lambda calculus and the (little 'c') Y combinator is fantastic. ▶ this video

This video (similar lecture, different audience) has the slides alongside the talk: ▶ this video Still one of the best programming talks I've ever seen.

Finally made an account to post in this thread. I'm rather early in my career doing mostly Ruby, Python and JavaScript things. As you might expect, I consume mainly Ruby, Python and JavaScript related talks. The first two talks that really blew my mind are: - K Lars Lohn's PyCon Keynote from 2016: link - Jim Weirich's (RIP) "Y Not" talk from RubyConf 2012: ▶ this video There are many other presenters who I have a good opinion of: - Raymond Hettinger: his presentation/teaching style is something I'd like to model my own after, also he gave the first talk on writing proper threaded/concurrent python that I was able to understand and make use of. - Brandon Rhoades: another speaker with a presentation style that I've found easy to follow, also he takes a little shot at the dd utility about 18 minutes into link ) - Sandi Metz: I started out in Python land and moved to Ruby land, where I was introduced to Sandi's talks. She doesn't talk about incredibly complex topics, but she's got insight into some really basic things that's helpful to new people who can't see the forest through the trees. - Robert Martin: I gather that his OO principles are not universally revered, but I find his talks useful. - Gary Bernhardt: his talks are interesting and entertaining in ways that most are not The list goes on, but I can't think of them all right now.

For those (like me) that prefer learning through talks and demonstrations, Jim Wierich gave an incredible talk on the Y Combinator at RubyConf 2012. Video: ▶ this video Code: link

Jim Weirich's "Y Not - Adventures in Functional Programming"[1] is perhaps the most entertaining and interesting technical talk I've ever seen. It would absolutely not be as cool or as fun without the live coding. Additionally, the incremental process by which he arrives at the conclusion makes the topic much more approachable. 1. ▶ this video

▶ this video This talk is a must-see, really shows off Jim Weirich's craft and overall ability to be a great pedagogue.

If you are curious about the topic, I strongly recommend watching these videos: Y Not- Adventures in Functional Programming by Jim Weirich ▶ this video Programming with Nothing by Tom Stuart link

Well, .NET's garbage collector certainly springs to mind. Not exactly in a good way. You know you have something special on your hands when GitHub refuses to show you a highlighted version of a hand written C++ file ( link ). Other than that, I remember my mind was blown a few times while watching Jim Weirich's presentation on functional programming all those years ago ( ▶ this video ).

A good video that made it click for me is the following, which derives the ycombinator from 1st principles: ▶ this video

Here is a good one that come to mind: 1. This one is alive demo where the speaker derives the Y Combinator from first principles. A really interesting exposition of functional programming at its finest. Link: ▶ this video
