Link rot is evil. Archive everything. The keyboard is king. Correctness over performance. Canonicalize, normalize, deduplicate. Don't repeat yourself. UTF-8 > UTF-16. Use static typing: good for tooling. Re-use; don't re-invent. Correctness, then clarity, then concision and elegance. Play devil's advocate. First understand opponents' positions.

Speeding up a numerical constrained quadratic optimization @OleksandrR.: I tried NMaximize with Method->{"RandomSearch",Method->"QuasiNewton","PostProcess"->"KKT"} on a similar smaller problem (7 vars), but it fails after a long time with NMaximize::cvmit: "Failed to converge to the requested accuracy or precision within \[NoBreak]100\[NoBreak] iterations. ". |

Speeding up a numerical constrained quadratic optimization @OleksandrR.: What do you mean by using FindMinimum via the "RandomSearch" method of NMinimize? |

Speeding up a numerical constrained quadratic optimization @OleksandrR.: I thought FindMinimum only gives a local minimum. |

Examples of (well coded) packages using custom notation @magma: By "source" I mean the "preferred form in which a programmer would modify the program.". |

Superscript prime symbol @OleksandrR.: The Derivative confusion only occurs with an apostrophe, not \[Prime]. The asker wanted to be able to use unprimed and primed in the same expression. |

Can mathematica show me a fraction with a repeating decimal notation? +1 for making the formatted output usable as input. |

Superscript prime symbol That causes q to display as q^\[Prime]. But you could instead use InterpretationBox[SuperscriptBox[name, "\[Prime]"],
Symbol[name <> "\[Prime]"]]. |

What are \[InvisiblePrefixScriptBase] and \[InvisiblePostfixScriptBase]? @kguler: So it seems like the Prefix one is meant as an invisible base character for sub-/superscripts that are typeset before the conceptual base character. But the Postfix one is still a mystery. |

Implementing efficient multiple undo @Jérémie: Kernel sessions are computationally intensive. Undo would be a feature of the front-end. While graphics can use a fair amount of memory, that problem is surmountable (works fine in GIMP). |

Pattern that matches colorstest[GrayLevel[0.5]]
"bad".
Obviously you can just test the heads against all you think of, but that's not robust if you forget one or if Wolfram adds another. |
