Expert to Expert: Rich Hickey and Brian Beckman - Inside Clojure

[@heepajunk]

The world needs a ton more of this type of content.

1:20 what clojure is 1:38 founding ideas of clojure 4:00 why pick Lisp as a base language for clojure 7:11 clojure's evaluation strategy 8:10 how is clojure 'functional'? 13:35 clojure's data structures 15:10 numerics 17:20 //board session// 18:50 how is list different from vector? 20:05 vectors and maps are .. functions! 23:04 two phase syntax (code as data, data as code) 28:05 *** moment of violating immutability *** 28:15 interop example 29:30 clojure concept of identity, in terms of mutability and immutability (how does clojure navigate both) 30:40 persistent data structure 32:25 how clojure implements persistent data structure (hash array mapped tries) 37:25 identities in clojure 38:00 identity and value in OOP perspective 40:06 how clojure fixes the conflation of identity and value (atom, ref) 47:36 example of transaction

[@Korupshenv1]

I think talking about Clojure at this level shows how distinct and unique the language really is compared to others. Rich has done an excellent job on reviving Lisp for the new era where concurrency and immutable data structures should be fundamentals within the language itself. Targeting the JVM was definitely a smart move on Rich's behalf. It's very rare to see this kind of interoperability. Thank you for the upload.

[@christgar64]

Also it targets the CLR of .NET

[@pragyandas]

Clojure has made world a better place...Simply Genius...

[@kshahkshah]

That explained a *lot* of Clojure concepts very very succinctly. Namely what that community means when they refer to 'persistence' and how that affects time complexity of standard operations. Awesome interview.

[@klgraham]

This sold me on Clojure.

[@abhisheksingh-li6zo]

+Kenneth Graham i can,t understand what u want to say ?? are u mean that u got job in clojure after seeing this video,, how this is possible..?

[@klgraham]

+abhishek singh :-) No... Just that Clojure is a language worth using.

[@hariharanviswanathan242]

Rich is a genius. Clojure (Lisp) + Haskell + Erlang (concurrency constructs) = ❤️

[@vamsideepakampolu8546]

This seems to be the most non-abstract Rich Hickey talk on the internet, I did not understand the last bits but I now know that they exist which means that I can work on figuring them out later.

[@WilkerLucio]

fantastic presentation, Clojure is such a piece of art :)

[@jasonofthel33t]

You're welcome!

[@RogerKeulen]

Thanx for putting this on KZbin Jason !

[@freerunkevin]

What an enlightening talk! They should make some of these concepts into college material, e.g. designing and implementing a persistent, immutable set datastructure. This really shows where these abstract concepts come together in the real world.

[@panhao356]

Great speech. Expert to Expert is really insightful.

[@abpdev]

This is an amazing talk!

[@seyiakadri]

Great. Clojure is it.

[@АйбатАманбайұлы]

Best intro to Clojure

[@ThomasGoossens]

Great conversation! Thanks!

[@cusnaez]

Best introduction to Clojure ever!

[@RogerBarraud]

Not really - See Rich Hickey's YT vids for even better intro / intermediate / advanced coverage! :-)

[@kenzo0622]

This is a great talk. Thanks!

[@RogerBarraud]

Great talk. Good mix of conceptual and concrete.

[@artist6000ish]

at 50:41, Rich cut Brian off, but Brian's question was about the mutable data structures in Java and .NET. It's unfortunate because Rich response didn't make sense without that qualification where he says "you don't use them"

[@laurelsporter]

Great to see something other than one-way talks. Thank you, Algorithm. Around 45 min...x86 has a number of compare and exchange instructions, and have retained that terminology for it for many years, as they've added more of them. Windows' library writers probably derived their terms from Intel's hardware level vocabulary.

[@captaincaption]

The algorithm pulls out some diamonds from the rough in a whole for sure. And that's why I continue to use KZbin.

[@elgireth]

Great stuff! Evolving reference feels indeed like a dual of Observables/Streams. And swap is like scan in streams. Though scan takes the latest value & the state built only in that stream to produce a new value where swap can take any other state too. How would a transaction look like on e.g. 2 observables/streams?

[@DanielBeecham]

This was great, thanks.

[@hertzbergny]

love how nerdy as fuck this is

[@creativefeather2968]

I think you're conflating nerdy discussion and meaningful discussion, lol. I'm just learning clojure and this helped me understand the language in a much more meaningful way than the documentation on the website has so far. I'll give you though, if you're learning or know clojure, you might be a nerd :)

[@Kenbomp]

Nice. Swap reminds of the small talk becomes command.

[@valentinzambelli9930]

Even if you are Rich Hickey you still have to whiteboard code in interviews...

[@adrbaz]

😂

[@ycombine1053]

When writing concurrent programs in your current language is so hard that you write your own Lisp lol.

[@laurelsporter]

After you've gotten used to Erlang or Elixir, it's not much of a stretch, and Erlang was definitely an inspiration for Clojure. That'll really change how you think about concurrency and parallelism, being used to more common languages. But, even with the niceties of Elixir, the BEAM (Erlang's runtime/VM) just doesn't lend itself to general purpose programming.

[@eugenemosh3658]

Thanks!

[@mhameedmmd]

my life is changed now !!!

[@abhinavomprakash4884]

When the creator of clojure says multi threading in java is complicated.....

[@UberOcelot]

This was like an hour long mental message, does it get better than this?

[@RahulGaurh4x]

man oh man ...if I could be a centage of programmer mister rich is

[@Simon-xi8tb]

Rich Brickey and Brian Hickman

[@Evan490BC]

(greatp (watch 'Rich 'Brian)) ; => T

[@willmcpherson2]

The persistent data structures are really cool but man I would not enjoy implementing that

[@jungjunk1662]

Why is the guy wearing a 🎩 inside?

[@alehatsman8550]

Hello guys, I am from 2018 and the most popular language in the World is JavaScript.

[@mrsozekaiser9299]

:))

[@christgar64]

I am from 2020 and JS is still very popular but equally hated.

[@n30v4]

Im from 2021 and JS is still… await … what??? Resolve that now! What do you mean I’m rejected.. ~shooting in background~ Hello I’m from Microsoft. .NET is coming. And can’t be stopped now. Since Billy the swag Gates is divorced we are concentrating on a younger audience.

[@PatternShift]

I am from 2023! And JavaScript keeps getting more popular despite being bad, but it's ok, Microsoft is slowly taking over the language and ecosystem and fixing the fact that it's not C# by turning it into C#, one TypeScript feature at a time.

[@utkukaratas]

2024 - JS and his crossdressing persona TS doesn’t seem to have lost steam at all. There’re even competing runtimes for backend use other than Node - Deno, Bun. The whole ecosystem of its underlying tools are slowly being rewritten in Rust.

[@MinNyeAccount]

I understand nothing of what they are saying.. but i have seen the entire video.. ??

[@ericlubisse8461]

+MinNyeAccount mmm...how did you make it to the end of the video? Anyway, have a look at this www.braveclojure.com/

[@micheldibjorge7517]

Relax it is normal, study more about computer science and come back in a couple of years

[@trwd3000]

These guys should dress more like the rock stars they are.

[@RogerBarraud]

I think you'll find they *did* :-)

[@MIIIG]

He use worm brackets )))
