Hi there,
Is it possible to access the IB software somewhere? I'd be interested in hosting an IB with some friends and we were looking at your software and it seemed nice, but I saw no link to the code on this website, so I wondered if it was available for download. If there's a link available to the repo please send it over; we'd be grateful.
Thanks for your time and congrats on having such a pleasing IB.

Hello! Emoji Image

Mathchan is a fork of Vichan (https://github.com/vichan-devel/vichan) which is an IB software that will likely serve your purposes.
Mathchan's own source code is not public yet.

Good luck developing your image board!
>>
It's literally just vichan with math embed support.

Hello, everyone!

Hopefully at least in the meta it is allowed to discuss the rules, or at least ask the creator's opinion of how to interpret this one.

Rules:

"Do not ask for Mathchan users to become your contributors, collaborators, volunteers, team mates, mentors, and so on whether for free or for compensation"

Is it true that, for example, you can't even leave your email or telegram? In case someone also wants to research or discuss a topic or article with me in more detail, e.g. at zoom?

Example.
User: Hi mates. Maybe someone is reading
Helemsky Lectures and Exercises on Functional Analysis, would like to discuss some problems and move together from chapter X, having worked out the links to one article there?
Mod: BAN

Hello!

When it comes to any rule, Mathchan staff shall always take in consideration the perceived intent of the poster. Only posters that are perceived to be intentionally malicious will be met with a ban. Therefore, if a poster has good intentions but uploads something by mistake, or unintentionally posts something that Mathchan finds undesirable, or accidentally skirts Mathchan's rules without knowing so, their thread will be moved to an appropriate board and/or they will be warned why, but the poster will not be punished by a ban. If you are not repeatedly and delibarately trying to infringe Mathchan's rules, you should have no fear at all of getting banned. Any goodwill effort to contribute to the body of knowledge of Mathchan is welcomed and appreciated and any potential missteps will be met with leniency and not punishment.

When it comes to the specific rule you're quoting (i.e. Rule 5), Mathchan only looks to host useful and valuable content. To be specific, Mathchan only looks to host content that is of practical value (i.e. guides, walkthroughs, explanations, tutorials, how-to's), or organic discussion that is in the interest of multiple people, and not just the OP. Without this rule, we would quickly become overwhelmed by those who are asking for something (e.g. "How do I do my homework?") and very few people would be contributing something. It's an order of magnitude easier to ask for something - especially with hard subjects like math and science - than it is to contribute something in these subjects. For this reason, on-topic boards can only be contributed to, and can never be solicited from. Creating a thread on Mathchan is supposed to be analogous to your lecture podium; you are supposed to showcase everything you know about what you are talking about, potentially answering any questions that posters in your thread might have. It doesn't make sense to assume a lecture podium and then ask your attendees to teach you something, nor does it make sense to assume a podium and then say nothing of value to the audience.

Classic examples that would violate Rule 5 because they are not considered sufficiently valuable to Mathchan are:

>you are supposed to showcase everything you know about what you are talking about, potentially answering any questions that posters in your thread might have. It doesn't make sense to assume a lecture podium and then ask your attendees to teach you something
But questions will facilitate discussions. I don't see someone talking about their i.e. engineering experience unless asked by another poster. In that case I don't see an issue as the topic is more obvious and people will still be able to have discussions about it. People would probably post more if there are specific questions being asked. Your rules are very poorly worded, for example 4g:
>Avoid discussing views and opinions of popular individuals (celebrities, youtubers, social media influencers, ...)
you could easily be talking about the works of any popular mathematician.
>>
>>566
>But questions will facilitate discussions
Well, first of all, I want to clear up the vision for the kind of content that Mathchan looks to host. The potentially surprising truth is that I don't actually want there to be much of a discussion on the on-topic boards such as /math/. Let me put it like this: 4chan is known to have image dumping boards such as /gif/, /wsg/, /c/, /cm/, /w/ etc. Similarly, Mathchan's boards are intended to be dumping grounds for mathematical knowledge, and that is supposed to be their primary purpose. If there's a thread about calculus, I want people to dump everything there is to know about calculus, just like if there's a thread about K-On on /c/, anons dump any images that pertain to K-On, even though they don't even necessarily discuss K-On at all.

You may pick a book, make a thread, and post every single theorem in the book, with zero discussion. That thread is, in fact, what I would consider to be an ideal Mathchan thread. Discussions in the thread are not forbidden of course, but they are only secondary. The primary objective of Mathchan is to have as much mathematical content as possible, and only the secondary objective is to enable discussion of this content. You should try have those order of priorities in mind.

What this means in practice is that if you make a thread on, for example, combinatorics, you should focus on posting everything you personally find interesting or important combinatorics. You should not tailor your thread in such a way invite other users in (e.g. "Does anybody here know combinatorics?" "Does anybody wanna try this problem?") and you should focus solely on posting about combinatorics itself. If other users contribute problems to your thread or eventually take over your thread, that's fine. If nobody does, that's also fine. The point is, you should just create a thread on any topic you want, and elaborate on it for how many posts you want, with little to no regard to whether there's anybody who actually cares about that topic and will post in your thread.


The bottom line: please treat Mathchan as more of a content dump (i.e. more like 4chan /c/), and less of a discussion forum (i.e. less like 4chan /a/).

>Do you think imageboard users are interested in discussing advanced science and mathematics?
Some are and this site is for them.

>also what is your speciality? math? chemicals?
My speciality is making this website and when there is nothing left to do I will hang around /meta/ and /dev/.

>can i post drug making tutorials here?
That's impossible to moderate without lawyers and it would quickly scare off my advertisers so Mathchan won't be allowing that.

My apologies if there IS indeed RSS for boards, I have not seen it.
So, I support altchans, I think they are valuable. However, I don't want to go to each chan to see what's up, and I like to see if there's RSS so I can add them to a list of RSS feeds I have for forums. Can a feature like this be implemented?

Hey I noticed links posted here get "cloaked" through the
exit?u=ID
endpoint. This is bad.

Link-shorteners make link-rot so much worse. When a shortening service dies, all links it resolved are lost forever too. By acting as a middleman, shorteners add another point of possible failure in the chain: https://www.economist.com/international/2012/10/13/cut-short

If mathchan dies, links in threads people may have backed up or archive die too. Perhaps this is OK or intended in sites designated for ephemeral discussion, but I get the impression your site is for discussion of pretty serious topics. Think about people, X years, who want to reference dead threads from here and do so through a 3rd party like the wayback machine. Or people today who simply want to read your site offline and want know where links lead to at least.
Don't mess with links.
>>
>>534
Links are cloaked and put through
exit?u=ENCODED_URL
in order to display Mathchan's exit point disclaimer. This is done for the following two reasons:
  1. To protect users from accidentally clicking on harmful links that are posted on Mathchan (such phishing sites or sites with criminal content) before Mathchan's staff is alerted and has a chance to take it down.
  2. To disassociate Mathchan from any websites users link to as well as hint the search engines that Mathchan does not want to associate with these sites (All user-generated links have
    rel="ugc nofollow"
    )

Trusted sites (like links to Mathchan itself) are not put through disclaimer and resolve immediately. Links to some well-known sites (like Google, Youtube, Reddit, Twitter etc.) are distrusted by default because privacy conscientious users may not agree with privacy policy of these sites and do not want to let them know Mathchan was the site that referred them. Therefore, these sites have to go through the exit point too. When user settings becomes available there will be an option to whitelist certain sites in order to circumvent the disclaimer for sites you trust. URLs to websites that Mathchan trusts are going to have direct links but for now
\url
and
\href
commands put all URLs through the exit point.


>If mathchan dies, links in threads people may have backed up or archive die too
If Mathchan is recursively mirrored then exit points ought to be mirrored with it too. Exit points contain a real URL so there would be no issue following the links on Mathchan's future archive.

Also, URLs are not shortened, nor encrypted. They are just encoded and can be easily reconstructed by replacing
._-
with
+/=
and running them through a base64 decoder (which is the current way Mathchan encodes URLs). Creating a URL shortener or encrypting URLs was in consideration but that would require us to maintain database of shortened URLs or an encryption key with no real benefits of doing so. If any of these are lost, all links on Mathchan would be dead. Unfortunately, encoding URLs has a signiPost too long. Click here to view the full text.
>>
>>535
You know, I was interested to ask this because this is the only image board I can name that messes with URLs. Somewhat reminded me of lame forums that you needed to register to follow links.
>Search engines can easily consider
https://terrorism.org/
a URL slug and tank Mathchan's rankings

Now that I think about it, I don't remember making a search on google and have an imageboard be one of the results, even when there's a thread that fits that search query better than any of the results that actually come up. Imageboards do come up if I search the name, so they're not all blacklisted. It seems (mainstream) search engines don't regard imageboards highly.
Is this actually because chans have an unusual frequency of naughty links? If that's true then cloaking is a good move for Mathchan. Or is that chans simply don't practice aggressive SEO to earn a place in the first page of results?

I appreciate that resolving
exit?u=
doesn't rely on a database, and the encoded URL is just that, it can be decoded. But is a nebulous (AFAIK) search engine optimization principle worth the inconvenience? I think you downplay how inconvenient it is:
>If Mathchan is recursively mirrored then exit points ought to be mirrored with it too. Exit points contain a real URL so there would be no issue following the links on Mathchan's future archive.
I highly doubt there will be an anywhere near competent Mathchan archive. Only 4chan has dedicated archives, other chans at most have individual pages saved on the wayback machine. Links in Mathchan are broken in the Wayback Machine, and they're also broken when casually downloading one thread with
Ctrl+S
.

You underestimate your users' incompetence, and underestimate their competence at the same time. You expect users to be able to do recursive mirroring or base64 decode URLs. But you don't expect them to think before choosing to click link so you greet them with an obnoxious "Are sure you want to exit?" page. Nor do you expect privacy-conscious users to configure their own browser to not send referer headers, if that's their concern.

>this is the only image board I can name that messes with URLs.
This is also one of the few imageboards with significant innovation, which comes with some responsibility. If we are going to provide users with a rich markup that can embed URLs, LaTeX figures etc. then we have to think about how we are going to do that securely. We could've allowed embedding URLs like javascript:while(1); that would've crashed your browser but we don't want browsing Mathchan to feel like a minefield.
\url{...}
and
\href{...}{...}
are there to allow posters link to other websites but users should not be afraid of clicking them, voluntarily or involuntarily.

>Is this actually because chans have an unusual frequency of naughty links?
Yes, and anonymous image boards in particular have a troubled history with this stuff. There is a CSAM linking spambot that plagues all imageboards including Mathchan and we already have two of its IP addresses permabanned, though this one will be thwarted by Mathchan's captcha.

>But is a nebulous (AFAIK) search engine optimization principle worth the inconvenience?
This is not just for search engines but for your security as well. If you're browsing Mathchan at work or school, you may have to install their root certificate in which case your organization will act as the man in the middle between you and Mathchan. If they scan the page you're looking at and find
<a>
tags linking to a blacklisted/criminal websites, you will be in trouble. Even if your connection is secure, it's better if you can review the link before following especially if it's given using
\href{...}{...}
(e.g. Click me). Malicious users may also try to conceal a link using
\color{...}
or
\colorbox{...}{...}
in order to trick you into clicking it. They may also use
\href{...}{...}
to make it look like
\url{...}
and triPost too long. Click here to view the full text.

It has been a week since Mathchan has been launched into existence - last Saturday on Christmas, 25th of December 2021. Today, it's New Year's eve. Mathchan wishes you all a Happy New Year! We hope you continue following us as we make this website ever more useful and, hopefully by the end 2022, we will make it feature complete and bug free.

To celebrate this occasion, Mathchan implemented a new feature today - one without which Mathchan would certainly be unusable: instantaneous post prevewing. The feature is toggled by checking the Preview Post check box, or by pressing ALT + P while focused inside the comment text field. Upon activation, a new section will appear rendered identically as it would be if you posted it. Almost all of Mathchan's markup can be rendered instantaneously. The commands that cannot be rendered instantaneously are the ones which require server rendering, such as
\chemfig{...}
and
\tikzpicture{...}
. To render these, simply stop typing for 25 seconds and they will be automatically rendered too.

In the first week of our existence, we were raided by the folks from Soyjak Party. Because they are among the first users of Mathchan (and thus Mathchan's historical oldfags), I have banned none of them - in fact, two global emojis were added in order to honor your legacy to this website - soyjak and thrembo . In addition, to accommodate our visiting guests from Soyjak Party better, a new board - /ret/ - Retards - was created. Users from Soyjak Party are welcome to continue their ironic funposting in /ret/ - Retards and /test/ - Testing/Spamming boards, as well as voice their criticism against the scientific establishment in /sss/ - Stuff Scientists Say board.

That is all for today.

Once again, happy new year!

It looks like your browser is inverting lightness, so the text color ends up clashing with the background.

You'll have to either ad block the background:
https://mathchan.org/assets/bg.png

Or you'll have to use the Stylus extension and add the following rule
body { background: #2f2f2f; }

Or you'll have to wait until Mathchan gets a dark theme.

yeah that's fine, again i wrote a stylish CSS anyway and considering this is quite new i don't expect everything to work ootb

by the way, it seems like when you delete threads/posts they are just deleted in the database, or something idk how vichan works but point is that they're still accessible, just hidden
files however seem to be gone

as a result i have recovered some old threads and many test threads on this board alone
what will i do with them? i don't know, but i have them

anyways, cool site lukyon (and from what i hear, friends)
let's make this chan great

>by the way, it seems like when you delete threads/posts they are just deleted in the database, or something idk how vichan works but point is that they're still accessible, just hidden
There are also hidden boards like >>>/polsci/ and a few others.

Some threads are actually still in the database but hidden, while those that you recovered were residual due to a bug because this site is kludgy as fuck. It will take some time to make it stable, which is why we don't advertise this site anywhere despite it being online. Though there is nothing in those threads except embarassing shitposts and test posts to amuse yourself (like this one https://mathchan.org/meta/thread/236)

Quora is horrible.
