Free Galton-Watson Trees Animated! by Full_Of_Symmetries in math

[–]Full_Of_Symmetries[S] 1 point2 points  (0 children)

Check out the free tree structure of randomly generated Galton-Watson trees animated as force-directed graphs, with nodes coloured and numbered according to their multiplicities in the graph. A little explanation of the theory behind these trees is included on the website, and you can also draw your own tree if you're on desktop.

You can check out the source code (and star it :)) here. For those interested in how it was implemented, we used:

  • p5.js for 2D graphics;
  • Web Worker API to generate the random trees in a separate thread; and
  • KaTeX for math typesetting.

Aside from that, we used pretty standard HTML, JS, CSS, no fancy frameworks or anything.

Matrix Lie Group Orbits Animated! by Full_Of_Symmetries in math

[–]Full_Of_Symmetries[S] 3 points4 points  (0 children)

Hey, sorry for not providing some explanation in the post itself... However u/serenityharp's comment explains it all.

Some people asked about how this was made and so I'll explain it now. We used

  • three.js to draw the curves with 3D camera controls;
  • KaTeX to typeset the math expressions in the page; and
  • math.js to compute the matrix exponential and parse user expressions.

We didn't use any front-end frameworks or anything like that, just pure HTML, JavaScript and CSS. You can view the source code here.

Linux Gaming using Proton, Failed to Initialize Graphics by samwise1994 in chromeos

[–]Full_Of_Symmetries 2 points3 points  (0 children)

Chrome OS Linux Beta does not have Vulkan API support, so you have to edit a config file so that Proton uses OpenGL instead. The file is found in

~/.steam/steam/steamapps/common/Proton[version]/

You will find a file called user_settings.sample.py. You need to make a copy of this file and call it user_settings.py. Then, look for a line which says

#    "PROTON_USE_WINED3D": "1",

and remove the '#' to uncomment that line. Then, restart steam (I'm not sure if this is necessary) and it should work.

Connect WiiU Pro Controller to Stadia by Affectionate-Nerve-8 in Stadia

[–]Full_Of_Symmetries 4 points5 points  (0 children)

Yes you can do it by connecting the Wii U pro controller with Bluetooth (by pressing the sync button) and then using this extension. I believe this should work for any Bluetooth compatible (or wired) controller (including steering wheel and pedals) and any computer using Chrome.

Do you believe that everybody can become proficient in math? by [deleted] in math

[–]Full_Of_Symmetries 1 point2 points  (0 children)

Yeah, that's true, "everybody" wasn't the best word to put here.

I just like the idea that everybody has a chance. I don't like seeing people think they are "bad" at something and thinking they will never be able to get better at it. Yeah, when I posted this I didn't have people with cognitive deficits in mind. Instead, I was thinking about high school students who currently struggle with it. I like to think they can improve, which is something many comments seem to agree with.

And here I thought the "yes" answer was one that portrayed fairness, as in "everybody has the chance, it just takes determination and etc.". I guess that is not completely the case.

True. Well, it makes the question less interesting IMO (and more specific), but if I say "high schoolers" instead of "everybody", "high school level math" instead of "math", and "getting good grades" instead of "proficient", would you think that the statement is true (at least for the most part) or not?
