I was lucky enough to meet the guy behind mathigon for dinner a long time ago. He's brilliant! I'm always excited to see what he is up to! Glad to see this voted up.

Yes, why did you make this if asciimath exists? Not to say that you shouldn't have made it, but what does it do that asciimath doesn't in your view? Just curious to understand
Re:Against 3x Speed on Monday December 20, 2021 @12:04AM (#29621728)
I get the point you're making - but honestly I have to raise the counter argument, which I think is equally valid. Take for example, the average lecture video. The information density is so low, that I'd imagine that a 60 minute video could be compressed into 10-12 minutes without any loss of information. It really depends on what you're listening to/watching.

Oh, I want to be first in line to become the first official General Grievous
I agree with you 100%! But a good resource is never a bad thing :)
Oh awesome, thanks for picking that up, will fix asap :P
I'm making youtube videos

And I'm also working on a website that has a fair bit of the foundations:

https://treena.org/

Admittedly, we don't have a huge amount of the higher stuff yet. But we are making our way through steadily :) Hopefully it's of some help to you

It looks nice. But when you ask something like "Should I continue working on it", that is a loaded question. What are your goals for the project, and at what point would you say that this project is no longer able to meet those goals?

I made this as well. Hopefully this helps too: https://www.youtube.com/watch?v=HSwefZMyjV0&t=14s

We've also got lots of these over at treena.org. We are planning o make explorable lessons. Take a look at https://treena.org/lesson/parametric-functions and try playing with all of the obvious things.

Are you sure this counts as cheating on your wife?
Re:Ask HN: I Am Looking for a Mentor on Tuesday November 05, 2019 @12:35AM (#21449926)
When you engage into any transaction, you have to gain something and the other person has to gain something. You'll find that very few people are going to be willing to give up their time to help you, and those that do will do it because they feel good giving up some of their time to help somebody who is really trying to learn on their own. So in that situation, you are getting much more than you are giving. If you're looking for somebody to help you out of kindness, which I'm happy to do in certain scenarios, I'd expect that you have:

(a) Shown them some research effort (and are) (b) Are asking very specific question that takes little effort on my part to help you with

I have to be frank with you, asking for a mentor to guide you through the basics is not really a fair thing to ask of anybody. Especially since there are hundreds of people who have given up many hours of their time trying to create learning material that you can use to learn your basics - they are all over the internet (googling learn to code will provide many useful hits). I worry that perhaps your idea of what a mentor should be, is not realistic.

You must take a greater responsibility for yourself. Remember, with enough effort, you can do it! If you need help along the way, there are many places you can go for help - (stackoverflow, discord chats, etc...)

Best of luck on your journey :)

Re:Dark mode using CSS blend-mode technique on Tuesday May 28, 2019 @11:55PM (#20036720)
This is probably a bad idea :P Blend modes are VERY expensive operations, running a blend mode over your whole site may set a few of your users computers on fire. I'm exaggerating of course :P but I wouldn't recommend it.
I'm working on something somewhat similar, here's an example lesson: https://treena.org/#lesson/vector-subtraction There are more on the home page.

It's not so mobile friendly yet. But the approach I'm taking is quite different :) Great work Mathigon!

Re:Ask HN: Why should I write tutorials/how-tos for others? on Monday December 03, 2018 @08:32PM (#18595057)
a) It opens you up to criticism, to find potential improvements to your style - if you think that your style can't be improved, then sure: hold onto it and never let it go!

b) If everybody held onto their knowledge because it was valuable, I'd venture to say that you'd only have a fraction of the knowledge you have now - since there wouldn't be any resources for you to consume yourself

c) It disseminates your work, more people know what you're working on, and that means that when you make a claim regarding the value of your work, people will take you seriously. How am I supposed to judge the value of your work if you don't have a readily available body of work for me to cross-reference against.

d) If your pattern truly creates value, then others will start to use it in software you don't contribute to; which will mean more rapid progress that you can again benefit from.

Human knowledge acquisition is not meant to be solitary, so if you don't want to share; thats up to you. But you need to realise that sharing is always a game of give and take.
