GSoC / OPW IRC AllHands this week
Hi, you are invited to the GSoC / OPW IRC AllHands meeting on Wednesday, June 26, 2013 at 15:00 UTC (8:30pm IST, 8am PDT). We have done our best finding a time that works decently in as many timezones as possibles. Please confirm at qgil@undefinedwikimedia.org so I can add you to the calendar invitation and I have your preferred email for other occasions. If you can't make it's fine, but let me know as well. Thank you!--Qgil (talk) 18:02, 24 June 2013 (UTC)

Future of mathematics editing
Hello. I'm en:User:Spectral sequence and your name here was given out by en:User:Whatamidoing (WMF) at en:Wikipedia_talk:WikiProject_Mathematics as being involved in developing the mathematics interface. I thought I would take the opportunity to make some suggestions: here's a compendium of some remarks I've made in other places over the past few days ... Looking forward to a productive discussion.

 * It would be interesting to know what the developers plans are for the VE mathematics interface, and I'm sure you'll find there's a lot of useful experience and expertise in the mathematics community available for you to tap into if you would share your thinking with us as early as possible.
 * I was able to add a formula successfully using the Σ icon but when I went back to the page to edit it again, VE just hangs: with Chrome 27.0.1453.110 and also with Version 26.0.1410.57 and Version 28.0.1500.95.
 * LaTeX box is very unforgiving of mistakes: hard to see how to respond to a markup error.
 * I certainly support the decision to use LaTeX markup: I had feared that VE was going to try to use a point-and-click interface for mathematics like MS Word, which would have been a huge step backwards. LaTeX markup will be completely familiar to anyone seriously writing mathematics, and the LaTeX engine is far more sophisticated on mathematics layour than anything else.  There remain issues over the way LaTeX (or any other form of mathematics) is rendered in browsers, though.
 * There is also the issue of whether you want the point-and-click interface to emit LaTeX markup, as $$2+2=4$$ or wiki markup, as 2+2 = 4, or mixed wiki and HTML as 2+2 = 4. If you mix them up, they look different, and that difference looks odd, as you'll see in this very post.
 * Something I wasn't able to test was whether and how VE would handle inline equations and displayed equations.
 * Questions of (1) whether VE could or should support point-and-click mathematics (for which you make a case) (2) whether VE should allow access to underlying LaTeX markup (which is presumably planned and which I strongly support) (3) whether access to underlying markup should continue via Edit Source (which has been stated by Jimbo Wales) (4) whether point-and-click interface should translate into LaTeX, Wiki or Wiki+HTML as underlying markup (I support LaTeX) (5) whether underlying mathematical markup should indeed be LaTeX or anything else (I maintain anything else would be very very sub-optimal).
