codeworld VS hello-express

Code World[1] is a great project that addresses a number of the problems from the article, with an eye towards using Haskell to teach children basic math and programming simultaneously. Code World directly addresses a number of the obstacles outlined in this article:

1. Using an online editor with a rich built-in library removes any toolchain problems.

2. A custom standard library simplifies pedagogically unnecessary details like Foldable

3. The custom standard library also avoids currying (f(a, b) for functions rather than f a b)

4. Custom error messages improve the feedback students get from the compiler

I would highly recommend Code World to anybody looking to teach programming with Haskell. If you want to teach Haskell in a way that fits the existing ecosystem, it's also possible to run Code World without the custom standard library[2].

Alternatively, I'm a big fan of https://code.world which is specifically geared towards learners who want to work up to making simple games. It's kind of a toy, but imo resembles a "real" programming language a lot more than other educational programming languages

Loose connection, but made me remember https://code.world/ uses a Haskell-like functional language to define still pictures, animations, or even games.

I second gloss! It's a bit limited (no sound, fonts, nor even text centering, but you do have support for vector and bitmap graphics, color manipulation, mouse, keyboard, and animations), but it's so, so easy to use that I not only recommend it (or the similar Code World) for anybody's first game, I still use it for my newer games.

Two that I can think of:

- Bootstrap teaches a toned-down version of Racket (i.e. Scheme): https://bootstrapworld.org/materials/spring2021/en-us/course... . It's taught in some schools as well as a comp sci curriculum.

- https://code.world/ teaches using a toned-down version of Haskell. To my knowledge it's not used in schools.

I had the silly 'fromString' error you get when using RebindableSyntax but had forgotten what to do next. Quick Google search and I hit on codeworld #59.

That's a matter of tooling and environment. You can have a look at examples of drawing animations with physics simulation and user input at https://code.world. It's pure Haskell code without any scary abstractions, just functions from state to the next state.

I'm not a user myself, but I understand Lambdabot and mueval depend on it. More generally, anything that executes Haskell code supplied by untrusted users would fit the bill. I don't know if CodeWorld for example allows user-supplied modules, but if it did they'd have to be Safe.

Postmarks runs on Glitch - or, anywhere else you can stand up a Node.js / Express app. Personally I love Glitch, and I've been using it for many years now for hosting demos and trying out different projects - in fact, my main links page runs on Glitch. The Postmarks developer Casey Kolderup works there, and Casey has made it really straightforward to remix directly on Glitch, or import from GitHub there or to another service of your choice - it has very few dependencies.

So kind of like https://glitch.com/ and https://inbrowser.app/ but somehow productized, has a bitcoin donation button, and uses iframes(??). Feels pretty slow too, but that might just be the HN hug of death.

The Glitch team has been doing some gardening of our own over the past few weeks: the latest addition to our new homepage is our new weekly feature, “App of the Week.” As I type this, we’re featuring a classic: Dan Reeves’ Nasa logo generator. Next week: your favorite app? Your latest creation? Send your submissions here and help us shine a spotlight on all the coolest (even in this heat) apps in the universe.

Happy June! Everyone seems to either be wrapping up the school year or finishing up projects at work ahead of trips to the beach – or whatever it is that humans do when it gets this warm out. Our team’s been busy too; in case you missed it, we launched a new Glitch homepage, created new starter apps to celebrate Apple’s expanding support for progressive web apps and open VR/XR, and made huge progress in letting the Glitch community tap into all of Fastly’s features for supercharging your apps – we’ll be sharing more about this very soon!

I’ve seen some people use Glitch for experimental web projects.

I'm making a custom heardle using the 'zayn-heardle' template on https://glitch.com. The search-bar for searching for songs is not working. It doesn't show any options to pick a song.

See you on glitch.com! Jenn, Director of Community 👽

I've implemented the package https://pub.dev/packages/sign_in_with_apple successfully both for iOS and Android devices (my back-end is glitch.com, copied from the package's instructions).
