Jin intends to print some site minicards for promoting Mathematica.SE at the WRI conference.

I suggest posting here the questions we consider appropriate, and voting on those.

Jin's guidelines are:

The idea is that when we pass out these cards to people, the questions are so interesting that they'd be inclined to get on the computer and type in the URL to find out the answer.

I prefer to have the 3 questions to cover different scopes of the site. All should have accepted answers. It'd be great if the question is in the "How to ... ?" or "What ... ?" format.

If you need to tweak a little the question title to meet the requirements, go on as far as the meaning is not distorted. And remember that both "serious and informative" and "flashy" questions are good choices.

I am posting below some questions already mentioned for this purpose in chat

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. If this question can be reworded to fit the rules in the help center, please edit the question.

    Many good questions below. I feel like voting for each and everyone of them, but that would be as good as not voting at all. I think everyone should restrict him/herself to voting on only half of the questions here. – Sjoerd C. de Vries Aug 30 '12 at 21:19

    Damn... I can't vote ... need a sockpuppet ... now – Dr. belisarius Aug 30 '12 at 21:24
  • @Verde Ah, I see. The trick I normally use is to add as many []() as necessary. See the answer I edited below :) – rm -rf Aug 30 '12 at 21:32

    Thank you for creating this post. I'll create the cards based on the highest voted answers next week! – Jin Aug 31 '12 at 17:10
  • I am trying to add a question (this one), but it is automatically converted to a comment ("trivial answer converted to comment"). How did you do it? – becko Sep 3 '12 at 2:08

    @becko Insert a few []()[]() sets until you reach the minimum answer length that doesn't get converted to a comment – Dr. belisarius Sep 3 '12 at 3:01
  • I wish the people who had down-voted answers had left a comment why... (And I'm surprised how many do have down-votes.) – Brett Champion Sep 7 '12 at 21:53
  • @BrettChampion I downvoted 2-3 suggestions only because they didn't have an accepted answer, which was a specific requirement from Jin. It doesn't reflect on the actual question itself (I've upvoted all of them and their answers) but rather that the user didn't bother to read the instructions above. I saw a couple of comments mentioning that it had no accepted answer, so I didn't make my reasons further explicit. I don't know about the downvotes on questions with accepted answers... – rm -rf Sep 8 '12 at 14:38
  • @BrettChampion That is not unusual, and it is OK. In meta, downvoting means "I don't agree", and is just a subjective issue. I myself downvoted one question because, although excellent as a question per se, I don't think it is a good match for a minicard. – Dr. belisarius Sep 8 '12 at 16:27
  • @BrettChampion Suppose you think we shouldn't provide Jin with a questions list, and let himself do the choosing. Then you should downvote my question here. Each question/answer in meta is like a poll. – Dr. belisarius Sep 8 '12 at 16:30

    UPDATE: I have created the minicard designs based on the highest voted answers: "What are the use cases for different scoping constructs?" / "Using Mathematica's Graph functions to cheat at Boggle" / "How to create word clouds?" The designs have been submitted to Moo.com and the cards will be made in less than 2 weeks. Thanks! – Jin Sep 11 '12 at 21:56
  • Closed, as the voting results have been used by now. – Sjoerd C. de Vries Sep 12 '12 at 9:10

How to compile effectively?

    Perhaps How to effectively compile Mathematica code? – Ajasja Sep 1 '12 at 6:58
  • I think that compile Mathematica code instead of just compile is redundant. – becko Sep 1 '12 at 18:37
  • @becko See for example this – Dr. belisarius Sep 1 '12 at 19:16
  • 1
    I did not know about that. Thanks for pointing it out. But I still think that compile unqualified is implicitly understood as compile Mathematica code using the Compile built-in function, in the context of this site, whereas any other use of the word compile requires a qualifier, such as Java compile, as is done in that example. That is just my opinion, of course. – becko Sep 1 '12 at 19:51

    This is a great question, but is the term hedcut sufficiently familiar? I, for one, didn't know it. – Sjoerd C. de Vries Aug 30 '12 at 21:17

    This question doesn't have an accepted answer. – Simon Woods Aug 31 '12 at 14:21
  • @Simon You're right. But the answers are quite good! – Dr. belisarius Aug 31 '12 at 14:33

No accepted answer, but I think it is OK since the top answer is CW.
