"I could keep frame rates in the high 20s even with hundreds of objects on the screen.

After some months of developing in a Lisp, the parentheses disappear and you only look at the level of indentation. Especially if using Parinfer for structural editing. It becomes like Python in that respect (except that the parentheses still are there, so in moments of confusion you can always fall back to highlighting the matching parentheses).

You could have Lisps using totally different Syntax, as long as they are internally parsed as lists (preferably stored as arrays, not linked lists).

Really good editing on this. I appreciated how many quick cuts and almost no downtime at all. Thanks for putting this out!

[@Taverius]

I've said this before, but after a bit the Parens Spam disappears and you just see the code, same as all the other syntax sugar from other languages - with the advantage that you never have to backtrack to figure out order because in a decent LISP, everything is prefix operator. Infix operator maths is honestly hard to read these days. Why the fuck would I want to write bar = x + y + w + z; when i can (+ x y w z). That only becomes more true as complexity increases. Also, it's become a chore to relearn the latest and greatest result of Greenspun's Tenth Rule (this time it doesn't suck, we swear) I'd rather just use the superior original.

[@georgerogers1166]

Racket is the result of a similar rule, Every reasonably sized Scheme program contains a bug ridden slow implementation of half of Racket, including Racket!

[@astroid-ws4py]

In math itself they define the + operator as a function from R×R to R as +(x,y) and say that just for the convenience or tradition it is written as x + y instead, But every Foundational Math textbook will say that +(x,y) is the real thing and with this notation the addition operation is defined/constructed which in lisp notation will translate into (+ x y), So lisp is actually much closer to the original notion.

[@isodoubIet]

@@astroid-ws4py "n math itself they define the + operator as a function from R×R to R as +(x,y) " No, they don't, they define it as a function whose domain is R (R^n, or N, or C, or whatever) and whose codomain is R (or whatever). Notation is not part of the definition. Postfix is way better than prefix anyhow.

[@astroid-ws4py]

@@isodoubIet The operation is defined as +(x,y) and only for the tradition they write it as x + y, You can check yourself the many books about foundations of mathematics and how they construct the + operation directly from bare principles from the naturals and up. So lisp is closer to the original notion syntactically.

[@isodoubIet]

@@astroid-ws4py "The operation is defined as +(x,y) a" I literally just explained that it isn't. You're confusing the concept of "binary function" with "function notation" which is totally unrelated. I could for example write a function like this: x y f z to indicate what we would normally write as z = f(x, y) and there's nothing you could do to prove that's wrong. Why? Because it's notation, and notation is irrelevant except for human convenience. Might as well say that functions are conventionally defined in Times New Roman and that writing them in Arial is wrong. Has about the same amount of meaning as your complaints about infix vs prefix.

That stands to reason (lame pun intended) because you can view Hindley-Milner style type inference as logical inference. In fact, I have found it helpful to view Haskell typing (which is Hindley-Milner, but generalized with ad-hoc polymorphism and whatnot) as specifying a kind of Prolog program which the compiler runs first to produce (either a type error message or) the actual code which is finally compiled.

When I first went to college and took my first programming course they wanted us to learn Scheme, another lisp dialect.

"Just do a base condition and call the program again" like what don't you get?

What he means by smalltalk being an "image based language" is that smalltalk isn't just a language, it's a whole environment/mini OS of sorts, and you have to build an image of that environment to use it. I personally dislike this, but it allows for some really cool stuff, as the whole environment is smalltalk. You have direct programmatic access to this whole environment and the language itself. Smalltalk has insane metaprogramming capabilities. In a lot of languages you have some sort of basic reflexivity, but in smalltalk you can define metaclasses, or even redefine the concept of a class itself, you can change the whole language if you want, it's smalltalk all the way down. It just has a small bootstrap and everything else is modifiable. It's an interesting language for sure, though outside of the assignments I had to do with it, I wouldn't build stuff with it.

[@AlexRodriguez-gb9ez]

Smalltalk took its image based development from Lisp and programmable semantics, and EMACS is kinda of a Lisp/image or Lisp machine. BTW programmable semantics like being able to change the meaning of cond, set, defun, let were sort of what the early definition of object oriented were (i.e: the semantics are objects in the code that can be changed).

[@djupstaten2328]

High 20s fps, with many objects on the screen. That blew my mind.

[@LambdaCalculator]

17:27 Don't let Uncle Bob's phrasing mislead you, spec/schema checks are usually separate from traditional style tests. The unit tests aren't the ones doing the type checking. The extra benefit you get from using spec however, is that it allows you to do property based testing (like Haskell's QuickCheck) which automatically generates and runs tests with a random set of inputs and edge cases that meet your specifications. And you can specify your expected inputs/outputs with more granularity than a typical ML style type system like Rust/Haskell/OCaml's (eg. you can specify value level conditions, like valid number ranges, list lengths/contents, substrings, and more), which makes it extra powerful. Not to mention that you can also use spec like a parser library and parse arbitrary text/data with it. There's a companion library (spec-provider) that uses spec to parse any examples of raw data you give it to generate inferred type/content specifications from them (like F#'s type providers) for example, so you don't even have to write those yourself either.

[@vikingthedude]

That’s amazing. I’m looking to learn more intermediate level clojure. Is there any good resource to learn spec that you know of?

[@sharos404]

I think I will give Clojure a go some day, seems quite nice. I think the way Uncle Bob presented it is pretty bad though, you can achieve this syntax in many other languages. In Julia you have several options: map(x -> x^2, 1:25) (x -> x^2).(1:25) 1:25 .|> x -> x^2 ... or for loops which actually gets vectorized (looking at you, Python): [x^2 for x in 1:25] I do understand that multi-paradigm languages can end up doing more harm than good by having all these options, but having the choice between tidy for-loops and functional style maps at the same time is appealing to me.

Just accept the suck and determine which version of suck you want to suck on* - ThePrimeagen, 2023 This is actually crazy 🤣🤣🤣🤣🤣 EDIT: I swear the ending got me rolling, didgn't expect that.

Take a look at his article named "NO DB"

[@LinucNerd]

"framerates in the high 20s"... Oh man... Say what you will about Uncle Bob, but this article is absolutely hilarious, probably the best joke he's ever made. Edit: Seeing some people in the comments taking him seriously, as if he is serious here, no this is very much trolling. I've seen the Casey video and a video on their email correspondence, but this article is a shitpost, you can't tell me otherwise.

[@CalvaTV]

For IDE support, if you like VS Code, there is Calva. (Yes, I'm biased.) And for those who like to hack their editor in user land like you can with Emacs, there is Joyride doing the same thing for VS Code. By some strange coincidence the language used by Joyride to hack VS Code is Clojure. =)

[@clickrush]

I'm regularly using the Calva standalone REPL to test out ideas.

[@BreytnerNascimento]

The prophecy of Brian is turning out to be really true, because you know it is Uncle Bob of Clean Code™ liking a language from a programming paradigm that by its very nature despise the rules of clean code.

[@AlexRodriguez-gb9ez]

What?! Uncle Bob loved Smalltalk then moved to Clojure. Smalltalk's version of OOP is very very different from Java/C++/C# ManagerFactory class inheritance BS. In Java doing OOP meant doing "cargo cult" programming having your control flow be split apart, using mutable state, having lots of code, etc... Smalltalk had 1st class functions, 1st class conditionals, metaclasses, actual message passing, Alan Kay always bragged that he could build programs in 5-10x fewer lines of code than in Java in Smalltalk.

I had a Prolog class back in college and I thought it was great. Loled hard at the ad-hoc invention of a typical Prolog exercise, though

[@bennymountain1]

If T-800 ran on Prolog, he would kill John Connor and then say: Yes

[@flippert0]

@@bennymountain1 Funny thing is, with some minor modification Prolog-T-800 could _also_ produce new John Connors.

[@RogerValor]

Uncle Bob clearly reminds me of an uncle, the one who always seems to talk how much he knows. I don't know why, but I never liked him, I just don't understand the fascination for his stuff. Clean code feels like code triplication around a God Object.

[@digitalspecter]

I never liked him because he seems to think he knows and understands more than he does.. and when you catch things where he confidently states suspicious things you become very wary of the conclusions.. they seem like post-hoc rationalisations rather than well constructed arguments.

[@gagagero]

One thing to add to the editors part is that using an editor that has some form of structural editing either built-in or as a package is a gigantic advantage when writing Lisp.

[@0netom]

programming in Clojure daily for the past decade almost and I've never been happier. started with BASIC on ZX81, then Forth & Z80 assembly on ZX Spectrum, Pascal & x86 assembly on DOS Delphi on Windows, then awk, bash, grep, Microchip PIC assembly, 7 years of vim, GNU Forth on Linux, REBOL, Ruby, Node, Solidity and "finally" Clojure with IntelliJ+Cursive (with some Emacs/CIDER keybindings), which is the most convenient bloatware of our times overall.

[@apollolux]

I learned Common Lisp for my Machine Learning class in college a few years ago and was surprised at how suspiciously simple it was to do things with it, however fast or slow it may have been, compared to other languages I already knew at the time like C++ or even JavaScript and PHP at the time (2017). The final project was to implement a solver for the game "Mastermind" and we were graded based on the order in which our groups of three or four took the most rounds to timeout our solving algorithms as the number of colored pegs to guess increased. IIRC my group finished 5th or 6th in the class even with our fairly naive mostly brute force approach that kinda looked like baby's first bubblesort but Lisp.

[@bennymountain1]

I like how Clojure is "The bestest language evar!" for people who used to code on Java. In a Bizarro-world version Mark Seemann praises F# as the new gospel. This parallel cracks me up for some reason.

If you don't know what image in Lisp languages is, maybe you should look it up before continuing rambling on. Yes, Smalltalk had it too. Go look it up.

If you're going to use Clojure you may as well take the extra step and try out Anglican.

9:37 so many parenthesis... Can we stop complaining about parenthesis? Because this would be the same in C or whatever: println( take( 25, map( square, range()))); How many parens ? YES

Nice to see some Clojure content. Would also be great so see reactions on one of Rich Hickey's talks.

[@TurtleCorporations]

Could you put the articles in the description? Like i get it i could probably just find it from the video, but it'd be nice to just have a direct link in case I want to check out the article/other stuff the guy has done. Thanks :)

[@salvatoreshiggerino6810]

I'd love to see someone solve the small syntax static typing problem. The ML family gets close, but I would consider that to be a rather midsize syntax. With Lisps you can just throw macros at the problem, but when everything is just symbols and s-expressions it all blends together.

[@overclucker]

It's all bit soup in memory. The goal of static typing isn't to keep the square peg from fitting in the round hole. The point is more along the lines of slapping your two year old's hand when they try to put the square peg in the round hole. I don't know where I was going with this, I just have invasive thoughts.

[@jsg240]

The Finnish company Metosin created a spec alternative called Malli. Its pretty fun to use once you get used to it and I prefer it over spec tbh. For the nested functions-lists, all those parentheses, you can use the threading macros to help you out, stuff like thread first -> and thread last ->> . I cant live without my Clojure REPL hahaha . Stockholm Syndrome Language indeed... haha

[@AhmedShariffGplus]

The "good == familiar" argument you made is the 'blub paradox' from Paul Graham's article. I was surprised you hadn't read his articles.

[@skilletpan5674]

To be fair back in the 80s and 90s compilers would generate different code when you didn't use { or if you did. So programmers were encouraged to not use them.

[@kc3vv]

20:00 I think this is not always true as there are new academic concepts sometimes explored in new langauges and these usually trickle down eventually to more mainstream languages.

[@szabolcsmate5254]

11:20 And that's why you never put the { at the and of a line, but only as the first non whitespace char of the line. So you see when it's not there. (But it should be there anyway.)

[@BryonLape]

I have preferred Lisp for 34 years.

Bob's wrong: PostScript was not based on Forth. Both drew inspiration from the same source: Burroughs Large Systems architecture.

Clojure + Hiccup + HTMLX is the new goat stack.

If clojure is less to do more, imagine Elixir that is less the clojure and more functionality with OTP power to build servers ^^. Elixir is kubernets and ngnix inside the language already

[@coolworx]

I'm just a hack hobbyist who uses programming as my version of crossword puzzles to keep my old addled brain spry. But in my novice experience watching the pantheon of programming gods arguing like Beverly Hills Housewives, my piddly conclusion is that programming is not much different from politics. We all assume the greater good is the ends, but we'll gladly kill each other during the means.
