css-turing-machine VS racket

> Technically html + css + user interaction can be turing complete: https://github.com/brandondong/css-turing-machine

Turing completeness is about what computations can be expressed, not what user interactions can be performed. The lambda calculus is Turing complete, but, if I whip up a lambda calculus interpreter and don't give it a print statement, then you'll never know anything about the computations it's performing.

Allow css in there and you get this

Seems like regex is not turing complete, bit its not a programming langauge ether. I thought i remembered that it was, i listed as one of the joke langauges as i know someome showed that PowerPoint is turing complete, but i think i mixed up regex and CSS here(that again is not a programming langauge but is in fact turing complete: https://github.com/brandondong/css-turing-machine)

It is definetly a borderline case (because of the need for clicking) , but html + css combined can be used to simulate the rule 110 automaton. Therefore it is possible to simulate a turing machine which means that it is in fact turing complete.

I understand CSS and I've done a fair bit of webdesign myself. CSS has evolved to the point where it can be used abusively. Hell some consider it turing complete (https://github.com/brandondong/css-turing-machine). From ads, to fingerprinting, to exploits there are valid reasons for wanting a little less functionality while still allowing for some basic styling. I mean, it's cool that there are computer games written in pure CSS and other neat tricks, but sometimes you just want a browser to behave itself even in hostile spaces. If that makes my locked down browser a "horse drawn cart" I'm happy to trot forward.

Yeah, someone even made a basic Turing machine to demonstrate it. As u/sext-scientist said, you have to click a button to perform each operation, but technically this means that you could write any program using HTML+CSS. Though the user might need an autoclicker to run even a "Hello World" program.

Racket—the Language-Oriented Programming Language—version 8.12 is now available from https://racket-lang.org

See https://racket.discourse.group/t/racket-v8-12-is-now-availab... for the release announcement and highlights.

Thank you to the many people who contributed to this release!

Feedback Welcome

Racket version 8.11.1 is now available from https://racket-lang.org/

Racket (https://racket-lang.org) has an IDE (DrRacket) which isn't EMACS. ARC (which powers hacker news) is (was?) written in Racket.

Nice! Repeating a comment I just made on HN: I signed up for RacketCon, will be joining remotely. I am looking forward to it a lot. Usually I use the Racket language perhaps for 10% of my personal projects, but I am currently writing a Racket AI book, so all things Racket are of current interest. Past RacketCons have been a lot of fun. I usually use Common Lisp, but Racket is batteries included Scheme, and more, and is a very pleasant language and ecosystem. Just in case you don’t have Racket installed: https://racket-lang.org/

I'd suggest Racket (https://racket-lang.org) which is a batteries-included language environment that includes scheme and has a lot of high-quality documentation.

Guile (https://www.gnu.org/software/guile/) isn't quite as learner-focused but is another great choice.

How did I get to the bottom of the page and not ONE person has recommended racket?

The Racket fork of CS supports Apple Silicon natively, and can be installed independently: https://github.com/racket/racket/blob/master/racket/src/ChezScheme/BUILDING Chez adds a few features (threads, ffi, ...) to R6RS; there is a useful combined index to TSPL4 and the CS User Guide at http://cisco.github.io/ChezScheme/csug9.5/csug_1.html

If you're using SICP in Scheme (or are you doing the JS version?) then you may want to look at How to Design Programs. It uses Racket which is a Scheme descendent so much of the language you've learned in SICP will work in it without issue. It also has a pretty good set of GUI and drawing capabilities you can find through the Racket docs page and will use some of with HTDP.
