Nice talk! When was it presented? Not in 2019, I suppose, when Clojure already was a big thing.

"We don't do that on the web. You ask for the page, you get the whole page. You get the entire value." That hasn't been true for some time. The concept of "web pages" is pretty much dead. From Github, KZbin, search engines, down to the smallest blog, there is no "page", there is only scaffolding and hundreds/thousands of micro requests interfacing through multiple programming languages to project an approximation of a final result that may or may not be relevant, and that's not even counting the additional injected third-party content and region/language/device-specific mutations. Immutable value? Far from it, I can't so much as read an API function descriptor on Microsoft via a known URL without it being forcibly translated into an incorrect spoken language because of my IP address.

A lot of these talks by Rich Hickey are > decade old so I'd check when this one is from for historical context.

JVM is a terrible choice...looking at BEAM for Erlang as an example. It was a shortcut to get libraries ready to run....I was looking at the Clojure market and it is at a 1.5 % in 2023....Nubank bought Cognitect to save their skin....being heavily invested in Clojure development. Macro are a disaster for maintenance and reading programs made by other peoples....Syntax is horrible...we have now at least 2 competitors for leiningen...maintaining and changing programs are the most important software life cycle activities. Airline industry is a model for documentation and should be a model for the software industry. if you look at clojure libraries documentation is poor, few real users in production mode. When you design a plane, documentation is 50 % of the total cost.

Is there a way you can code lisp and closure itself so that each function or module had its entire history in sexpression diffs, and if your program wasn’t working it could go back to a past version. You have to redefine def, and all the different types of vars.

28:45 OOP offers reusability in comparison to Procedural programming, bot not in comparison to Functional Programming. in comparison to FP, OOP offers higher speed. what a sly peddler of functional paradigm😅, exposing "lies" his first example of what "IT" is - is also confusing: the word "Information" in "IT" can be about a place, e.g.: a basket in a shop can be represented by a "place", in which you "add" products - it is "information", you don't have to represent it as a _"copy of the previous state of the basket with +1 product"_ , in order for it to be "facts". he gives an impression of an advertiser, doing sophistry, to push his product by all means. not the best way of presenting a great thing which functional programming is

@lordzilch 11 ай бұрын

Not at all. A basket where you can add products is a place, it is not a value or a fact. A value or a fact would be 'a basket with 4 products', 'a basket with 16 products', 'a basket with 10 products' etc. Contrary to that a 'basket where you add products' is just a 'basket with I don't know how many products', which is kind of worthless. That is exactly his point.

@David_Raab 2 ай бұрын

you add products to your basket. But at some specific time, when you picked up the basket, it probably was empty. You cann put stuff into your basket, and take them out, but during that events time also has moved forward. After you have put 10 items in your basket. Does it has affect the past and was your basket always full with all your items? No. When you picked it up, it was empty. This is a fact that never will change.

Chas didn't really explain why we'll love it anyway. On the more general note, I believe programming language philosophy is bifurcated into two groups: 1) those who believe a good programming language is chockful of "good" features, regardless of the complexity that may result; and 2) those who believe a good programming language is small, simple, easy to learn, easy to use, flexible, extensible, and productive. The software industry has obviously followed the first group. That's why we have large complex languages like C++, Java, JavaScript, C#, Scala, Rust, Swift, etc., and fairly complex languages like Python, Ruby, Clojure, Kotlin, TypeScript, Dart, etc. I prefer the second group which enjoy small simple languages like Smalltalk, Scheme, Go, Lua, etc. My favourite small, simple, easy to learn, easy to use, flexible, extensible, and productive programming language is Smalltalk. It's a timeless classic. In fact, this year Smalltalk celebrates its 50th anniversary: - kzbin.info/www/bejne/g3XKk4h5qah-l80 - kzbin.info/www/bejne/ioK0YqKOgpyBo9U

Go is the first group. It only deceives you to believe it is simple

@EdouardTavinor 29 күн бұрын

@@apestogetherstrong341 why do you say that? i find go to be a small, simple language, particularly when you start doing concurrency. every other language i've tried has seemed to offer lots of non-orthogonal functionality for this.

27:12 I can't understand that assertion: "In traditional Java programs you have a variable and it points to something but the thing it points to isn't a value". What does it mean it isn't a value?

@zhangjian3654 2 жыл бұрын

A value means something that can not change(immutable), Java objects' field is variable, but not value. you evaluate a variable you may get different contents, it can be value(say primitive type float/integer) or object reference. So we say variable is mutable. That's the source of complexity: you don't know who change the content inside variable when you use the variable as a foundation.
