ykonstant,

Hello all;

I am a mathematician working in homogeneous dynamics and number theory; I came here from Reddit looking for an alternative and still trying to get the hang of things. I see there is little mathematics activity at kbin.social at this moment, but hopefully this will change.

It seems that the administrator is currently swamped with the influx of users, but I am wondering if in the foreseeable future we can look forward to enabling some sort of LaTeX rendering in the threads, putting us far ahead of reddit in capabilities. Currently, I know only one federated place with LaTeX rendering, which is mathstodon.xyz. I wonder if the methods they are using can be transferred to kbin.

Right now we insert mathematical symbols on kbin.social directly from the list on the magazine column, but this is awkward and limited. Without any meaning to offend, I can see that r/math discussions tend to be less about mathematics and more "around" mathematics, and I have a pet theory that the lack of easy LaTeX input contributes to this phenomenon.

I would love it if this place could host a forum for mathematical discussion at all levels, and would like to hear other people's thoughts on this.

The extension rendered that operator as expected when using any of the first three delimiters. The fourth still did not render.

Unfortunately, the only extension I found that could automatically render was that one for Chrome. However, I did also find a website that had links to run a script version of MathJax to manually render a page.

That link is here: https://www.math.ucla.edu/~robjohn/math/mathjax.html
The way to use them is by creating a bookmark from the links it lists, going to the webpage to render, then clicking the bookmark. All LaTeX on the page will then be rendered.

The bookmark method works regardless of browser.

The options as I see it for the utilization of LaTeX in our magazine:

  1. For an in-site, native implementation, one of us would probably have to host their own instance of kbin to add in the code necessary for native LaTeX support to the magazine itself. The link for info on creating instances of kbin is here: https://kbin.pub/en.

  2. Although, kbin is open source and the developer, @ernest, has a public link to the the git here: https://codeberg.org/Kbin. So someone could create the code necessary for LaTeX implementation then submit a pull request. I'm not sure if ernest would approve the merge though since only the math and to an extent science userbase would have any use for that specific function.

  3. For an out-of-site, non-native implementation, there are browser extensions such as "TeX All the Things." The link is here: https://chrome.google.com/webstore/detail/tex-all-the-things/cbimabofgmfdkicghcadidpemeenbffn. I've made a test post to see how well it works, and it seems to work pretty well. Of the four test lines, only the last line failed to render. I'm not sure why the last line did not render, but here's an image of how it appears: https://drive.google.com/file/d/1SKofUBx6wIUhASG7LZBm5ad7sByiW3YW/view?usp=sharing

The pros & cons

  1. Pro: Native implementation, so no need for 3rd party support. Con: Would require that we abandon our current kbin.social magazine to create a new one on the new kbin instance.

  2. Pro: Native implementation. Con: Highly unlikely that ernest would approve such a niche pull request.

  3. Pro: Fairly easy to use. Can be implemented immediately without waiting for dev support from instance owners. Con: Some people may not want to use a 3rd party browser extension.

But I'll go ahead and link TeX All the Things in the sidebar for those who'd like an immediate LaTeX solution.

ykonstant,

@tau A browser extension is a good temporary solution; but does it work seamlessly across web browsers, like with Firefox and Safari?

ykonstant,

@tau Try writing the binomial coefficient as \binom{n}{k}, see if the extension has problems with the infix operator.
