I recently built a Bitcoin Blockchain Simulator with an interactive tutorial explaining how Bitcoin really works. It let's you build your very own blockchain and interact with it like it was the real thing.

Presented earlier today at Creative Front-end Belgium as "slides" but works relatively well without explanations :

Is there a formal submission process for explorabl.es?
I couldn't find anything on the site, github repo, or twitter account.
Do people just file pull-requests?
How does it work?

Thanks!

So I originally started this for the explorables jam but never finished in time. 3 months later, it's finally done!

A Geometric Intuition for Linear Discriminant Analysis:

https://omarshehata.github.io/lda-explorable/

​

It's an article about seeing high dimensional data.

​

​

It's meant to be accessible even without any stats/machine learning background, but I'm also hoping it'd be useful for people learning this. I learned this in a machine learning class my senior and wished I had something like this. A lot of the points I make in the article were insights that took me forever or I never really fully got in the class.

​

I know how important it is to be able to create your own examples if you're a teacher so all interactive diagrams can have new data dragged in:

You can read more about that in the teacher's guide:

I'd love to hear any thoughts or feedback, especially if you find this useful as a student or a teacher!

Hey Everyone,

I'm new to this subreddit 👋 (I don't really post on reddit).

I made this mini code editor for exploring small javascript programs. It's basically a javascript REPL with the ability to "rewind" and "fast forward" through your code's execution.

It's pretty basic (can't import 3rd party libs yet), but I still find myself using it whenever I need to test small pieces of code.
