@David All I can say is that I also see funny letter spacing on Ubuntu. If that were the only problem with Mma on Ubuntu, I wouldn't even mind, but it's bad to the point of not being usable.
I guess it's not easy to support a platform that changes every 6 month (and does things like introducing buggy drivers: stackoverflow.com/questions/8989102/… ) Don't be so quick to blame it on WRI, there are two sides here.

I was just looking up the good old `Flatten` help page. Is it just me or is the following sentence impossible to parse? Flatten[list,{{Subscript[s, 11],Subscript[s, 12],...},{Subscript[s, 21],Subscript[s, 22],...},...}] flattens list by combining all levels Subscript[s, ij] to make each level i in the result.
Thanks to Albert Retey and Rolf Mertig now we have an easy way to copy code from Mathematica. The source for the code copy palette is below.
Evaluate it to create the palette, pop it out from the notebook, and save it for permanent use with the Palettes -> Install Palette... menu item.
The ...
We've talked about here and there pieces of this, but what should go in our FAQ? What do you think needs to mentioned in our FAQ? Obviously, what is considered on-topic/off-topic, and quite possibly a number of items from this list. But, we should start making progress on this question.
(This is...
As we have entered public beta, it will soon become apparent that we need more moderator attention than can be given by the SE mods that have accounts here. We already have two users who have access to the moderator tools, and possibly one or two more soon, which helps quite a bit. But, we will ...
Please ping me with ideas on what should be improved in the code-copy palette. @Simon -- please also take a look, as you were the one who made the combined palette.
@rcollyer to whoever wishes to be considered: Please have a valid email address that the SE team can contact you at (and one that you check often). If not, no cake.
@Szabolcs Depends on the site... on some sites, users do nothing and you'll have to initiate closing/clean up work. Some sites, by its very nature, are rowdy and the mods will have to deal with troublesome users
On both my sites, it takes a fair bit of time to do clean up work around the site (although the flag volume is low)
However, I think that on this site, it should be a breeze, because we're very active here and most of us have the requisite badges and are already involved in a lot of the cleanup work
I will not deny that the two sites that I moderate have taken a fair bit of my time, but the primary reason for that is because there was no "community" to begin with – just a common idea. So that involves prodding users/educating them/answering on meta/etc. whereas we have a very strong community, which does all of that by itself
yeah, you can upload high res pics and it does the scaling automatically... Although your default icon might look the same, since it's 128x128, it will look better in the 512x512 version
not that it's used anywhere on the site, but I can manually check it to admire =)
@rcollyer you might also want to note in your post that a moderator's actions are binding – i.e., one click does the job. Perhaps if people are trigger happy, then it might be something to consider
Of course, one click can also undo the damage (well, in most cases)
@David I'm not sure I understand what you are saying. What should I check? All I need is to make sure this won't come up in my image uploader palette, and it won't confuse users. BTW I have a strong feeling that this is Windows-only.
I've just been testing the Flat attribute which I never quite got, in an attempt to answer a post from a couple of days ago. I'd be glad to know anyone's opinion on my conjectures...
Ok, I'm going to try to explain my best conjuecture as to how this happens, and don't even try to answer why. All this is my conjecture from playing around. I'll edit delete this note after I get your feedback, or delete the whole post if it's tooooo way off. But it makes sense to me as far as I'...
@robjohn I hadn't been using it much either, but after being persuaded to give it a try by Mr.Wiz, I have been using it a fair bit — sometimes perhaps even when its use is unnecessary
but in general, it's helpful with some functions where the meaning is immediately apparent from the use of an infix operator...
The problem with starting to use a new operator now, is that you'll have to worry about operator precedence all over again... do I need a () here? Does ~ evaluate before @, ...
@robjohn for the record I like infix notation; I have my reasons and I would be glad to direct you to them should there be interest. However the whole infix thing quickly became an ever more exaggerated running joke on StackOverflow.
@David yes, it only displays it like that, so it doesn't affect the palette functionality, but it can be very confusing for the users. I had to leave, security kicked me out from school (stayed too late)
@MrWizard I would like to see the reasons. I am always open to learning new ways to use Mma. It is just a method of entering the same code that one could enter with postfix, is it not?
@JM: I am going to stay with the green here (since the pings and things are green here, the same as they are orange on math.se), but I have been getting complaints about the violet that looks pink next to the green.
@Szabolcs Hi - I'm still reading all the previous messages :)
@yoda I think it's clear that we need a canonical question and answer about font embedding in PDF. The story is a complicated combination of both our answers, and my answer to this question.
I was probably a bit harsh, but it's clear that some fonts embed and some don't, and it depends how you produce the PDF and what format the font is in (OpenType TrueType flavor, OpenType PostScript flavor, TrueType, PostScript).
@Verbeia Also, Mathematica uses pdfv1.4, which is very old. Open type fonts will definitely not be supported, since that came out only in v1.6... I guess the version used has something to do with it
@yoda yes, that's also part of the story but while testing fonts for that LaTeX question, I found that Optima and most of the TeX-Gyre fonts were fine but Latin Modern wasn't. I think there is a distinction between PostScript and TrueType flavoured OpenType fonts.
I'm on Windows at the moment and just confirmed that Open Type "Sabon LT Std" doesn't embed properly (actually gives an error in Adobe Reader), while TrueType fonts with no true Bold weight, like "Poor Richard", comes up correctly on the same machine but aren't embedded.
The file size for the "bold" version is much smaller than the one that says the font is embedded. So there is no embedded font there. I will have to send that file home to check it on a Mac. (Very slow testing :) )
@robjohn yes it is just syntax; here is a transcript that includes me explaining to Sjoerd and yoda what I find good about infix. Please understand that I do not use infix all the time or where it would actually make code longer. chat.stackoverflow.com/transcript/5169/2011/11/20
I posted on Facebook, but I doubt it'll have much effect
I also posted a question on MathGroup today, and I put the new site in my sig
I'll post the announcement on Monday only. Weekend is not too busy, so it would get buried in all the posts. Monday is perfect, it'll pass moderation Tuesday
Yeah, I see. I don't know if it would be worth submitting a link to the actual site now that it is up? I haven't participated much in Reddit so I don't know whether promoting the same thing twice 12 posts apart would be frowned upon
@Sjoerd I want to write about the public beta in Monday, so it'll be posted on Tuesday. I want to geth through to more people. They don't read email so much on the weekend, and it'll get buried otherwise.
The biggest problem we'd like to avoid is posts like Gary's which are well meaning, but dont' fit in the SE model. We don't want to turn them away due to a bad experience
Here is a stab at a basic mathlink solution.
In the kernel that contains status information define this post function:
post[e_] := Module[{link},
Quiet[
link = LinkConnect["status"];
If[LinkReadyQ[link], LinkRead[link]; LinkWrite[link, e]];
LinkClose[link]
]]
If there is nothing to co...
btw, @SjoerdCdeVries @Szabolcs or any of the other europe regulars should consider throwing your name in the ring for pro-tem mod... good to have mods spread around different time zones
@yoda I can't commit now, I know I won't be able to be here every day in the following month. I don't want to take on a responsability, but of course I'll help out where I can.
@Szabolcs there are I think 3 MPIs here, a couple of Fraunhofer institutes, a Leibniz institute, another research centre, the TU Dresden and probably some other places I am forgetting, so lots of places she could have been
