It's... uh... been a while since this request was made. We require a few things before turning a switch like this - it's pretty harmful to small sites to have what is a large chunk of potential askers to be blocked. But... Maths isn't a small site, and it hasn't been one for a loooong time. So when this request was first passed into my radar two years ago, ...

You can experiment with the CD environment by including $\require{AMScd}$ in your post, and then using \begin{CD}...\end{CD}, as below. Here is an example using CD:$\require{AMScd}$ \begin{CD} A @>a>> B\\@VVbV @VVcV\\ C @>d>> D \end{CD}

Its days are numbered, starting today. You've voted, and while a little controversial, we'll support your decision. What remains is just the 'final arrangements', so to say. We'll need some preemptive cleanup Things with the homework tag applied to them do tend to have some issues. Take a stroll to the end of the very long tail - use your flags and close ...

We have implemented citations using the same model as MO using both Bibtex and amsref. Click link, then click cite on the link popup.

Please do not vote down this answer. Please vote this up if you think that blacklisting the number tag is a good idea.

Yes, I think this is both reasonable on general grounds and will help to ameliorate some "site flooding" issues we are currently experiencing. Are the exact numbers of 6 per day and 50 per month negotiable, or is it an on/off situation? To me 6 questions per day sounds quite reasonable, but 50 per month is small in comparison. It seems to allow users to ...

We have added a feature that can be invoked by moderators to transform a question or an answer from community wiki back to personal ownership. Once this is done the post will become immune from the automatic wiki assignment due to edits. This function is moderator only; when you feel a post should be immune from automatic community wikification, use the "...

Totally agree, and should have done something about this a while ago. To this end, I additionally propose making a new custom close reason: Seeking personal advice. Questions about choosing a course, academic program, career path, etc. are off-topic. Such questions should be directed to those employed by the institution in question, or other qualified ...

Ok, there's a warning now: This is triggered by a title matching ^.{0,30}(^|\W)(anyone|difficult|doubt|easy|hard|help|interesting|please|problem|query|question|someone|stuck|very)(\W|$).{0,30}$ ...so it heavily favors short titles - Tricky integration/functions problem would've warned, while Least squares problem equivalent to solving Poisson problem for ...

I think this comes back to the fundamental question of how people here envision the purpose of this site, and if the history of such debates is any indication, addressing the issue will lead to acrimony, drama, accusations, frustration, and other uncivil behavior on the part of certain individuals...over what I would like to remind people is ultimately just ...

As Mariano points out, this has been reported before. Because of that conversation, MathJax v2.0 includes an extension (the begingroup extension) that would allow you to isolate the effects of \def, \newcommand, etc. to a single question, answer, or comment, but it would require changes to the SE code to force that to be used. The changes would be to ...

We have enabled the 6/day, 50/month limits. Ideally we'd like to keep those numbers to avoid too many special cases throughout the network, but if they do turn out to be problematic, we can revisit this discussion.

I think this would be a very good feature. It happens to me too often that rejecting an edit is already too late - it was approved by other users. Even though there were much more obvious issues to address than removing a tag or adding two dollar signs. An example from a couple of hours ago: an edit changed "Leibnitz" to "Liebnitz" and was quickly approved....

So, to clarify and be able to indicate support: It seems to me that there ought to be a way (there should be a way; it would be a good feature to add to have a way) for moderators to "de-community wiki" under certain circumstances (maybe a quorum of moderators might be required, much like a quorum of users is required to close down a question?). Two such ...

It pains me to break this thread by fixing the issue, but here we are. :) We are now inserting \begingroup and \endgroup directives into post and comment bodies, so all command definitions should be scoped to individual posts. For now, I'm only enabling this on Math (and here on meta), but barring any issues this change will go live on all MathJax-enabled ...

We are working on a fix for the speed during render that should satisfy both the speed and instant preview concerns. It should be deployed tonight.

Sorry about being late to weigh in - I was busy last weekend. Why I support this feature-request? The norm re context that we have developed means that new questions at varying levels of mathematical sophistication often get put on hold for falling short of that standard. That is all well. But, the fact that the message This question is missing context or ...

I'm still facing very slow response, and now I'm facing it at home as well as at work. At work I run Firefox 3.6.18 on Ubuntu 10.04.2; at home I'm running Firefox 5 on Windows XP. The behavior at home is markedly worse now. Again, I'm two or three lines ahead when typing, and I have to wait about one to one a half minutes for it to catch up. Update, Jun 30 ...

I don't have much to say about what is going to happen. But I do want to point out something about what is going on. This point was sorta brought up by another user, but the answer was deleted. There are people currently removing the homework tag manually from questions. But I have seen some users removing it from "famous" questions which are old, and ...

I agree; there is much less need for new tags on an established math Q&A site than on a technology-oriented Q&A site. On a tech Q&A, users are likely to bring up questions about a new gadget or a new version of some software that was just released. Here we don't normally get questions about mathematical areas that were just recently ...

Ok - this check now only fires if at least 30 all-uppercase characters are entered for a post body, 15 for a post title.

I'm guessing that's not a bug per se, but human error from when Jeff said/did: I'm going through and manually merging all the Robin Chapman comments on math.se, I want to record some of the comments responding to his comments as I do so (I delete these afterwards, since after the comments are merged, it's no longer relevant.)

I have figured out both the problem with the \limits macro and with the failure to process the rest of the mathematics that it caused. It is basically as I outlined in my comment on @Zev's answer. The TeX input jax had an internal failure (it tried to use a null pointer), and that was trapped by MathJax as it was supposed to be. But it also meant that the ...

Unfortunately, while Math.SE is certainly one of the busier sites in the network, its daily activity levels are not yet at the point where it makes sense to switch over to the Interesting tab my default. You can read the details of the algorithm that powers that tab here. The most relevant part, however, is that it looks at the last 3,000 questions. This ...

Exactly how many active users do we have? I would suggest that 156 is a tiny fraction. I've been an active user of the site for a couple of years and had no idea that this discussion was taking place. I find it questionable that a discussion with a different web address (meta) can impact on the ordinary site. It seems a little like me getting a few of my ...

A quick note. We know what's going on, it's a change which had some side effects. I'll take a stab very soon. Update: It looks better now, as you need 60 consecutive unbroken characters to replicate instead of 20. However, it's not finished. Tomorrow I'll simply disable the line breaking shenanigans for comments that have MathJax in them. Update: this is ...

Now that Firefox 4 has been released, this is a real problem. The HTML/CSS rendering of MathJax here does not use the MathJax TeX fonts, but instead seems to use the default serif font of the browser, making the rendering look terrible. The problem does not occur in the demos on the MathJax site, which suggests that this is a problem with the deployment of ...

Thanks to Aryabhata, who solved the mystery in a comment: All four questions were asked by user7815, and that account no longer exists. That's unlikely to be a coincidence, so it seems that reputation is indeed deducted when an account is deleted. Now I'm just surprised that that doesn't happen more often. I guess account deletion must be quite a rare event. ...
