How to efficiently count occurrence of some element in a list? A few of the structure functions take patterns rather than functions. Pattern vs function feels redundant at first, but it's necessary/useful overall. |

mathematica for learning? @OleksandrR. thanks, that's good to know. @ jens i'm not talking about this question |

mathematica for learning? @rcollyer aye. my issue is that this is basically a more subtle version of those pictures you see on facebook that ask "Like for Eminem, Comment for Justin Bieber." poor justin bieber. for multiple reasons (some behavioral) it costs more to reopen than to close, so the system heavily prefers closing vs keeping open (i'd wager that's entirely deliberate, from what i've read from the SE people). I should make clear though that i'm talking about SO. i'm not worried about Mathematica.SE, just remarking on the what is quite possibly the root enabler of SO's hilarious culture |

mathematica for learning? im surprised there's no way to negate close votes. no wonder stackoverflow is a mindless clique |

mathematica for learning? it's important to understand that you don't need to know any math to use Mathematica. basically you just F1 all over the place (i am not joking, this is very important). the name "Mathematica" is particularly bad here. it's a much more general system than that name implies. for example, it has a lot of image processing stuff. you don't need any math to understand what Blur[ColorNegate[img]] does. even when you play around with, say, ImageTransformation which takes a function, it's not rocket science. 'mathematics' is simply not a factor in general Mathematica usage. |

Making a list from equations @user7540 a -> b is shorthand for Rule[a, b]. you can just do /. Rule -> List on the output |

Options which require RuleDelayed maybe there is an enourmous corpus of mathematica code somewhere (like that wolfram website i've seen), where you could extract these kinds of things semi-exhaustively? Just throwing that out as an idea. |

Why is there no PositionFunction in Mathematica? There does occur to me a 'reason' for why there is no PositionFunction, and that is that Nearest and Interpolation are "subject matter" functions whereas Position is more a language thing. E.g. hypothetically, Nearest could be constructed from a variety of data structures because all that matters is the mathematical distance between one unit and another, whereas Position is entirely about the specific list structure you are using. Not saying I'd agree with this, but there is this conceptual difference which may have something to do with the absence of a PositionFunction. |

Cell brackets on left side? damn. i was hoping to leave this one hanging open-endedly silent on the shoulders of WRI, so that it would nag and scrape at their subconsciousnesses until there was no recourse but to implement this feature. but alas @Rojo you've forced my hand. |

A simple StringCases problem probably .. is stronger precedence than ~~ so you're asking for repeated ")" (if you FullForm you can see this). also look into Logest/Shortest |
