Mathematica apprentice
My gravatar was made with the following Mathematica code:
Graphics3D[{
GrayLevel[.3], Specularity[White, 15],
Lighting -> {{"Directional",
RGBColor[.3, .3, .4], {{5, 5, 10}, {5, 5, 0}}},
{"Point", Black, {12, 3, 15}},
{"Point", White, {12, 3, 4}}},
KnotData[{"TorusKnot", {2, 5}}, "ImageData"]},
ViewVector -> {{0, 0, 5}, {0, 0, 0}}, Boxed -> False,
Background -> None, Axes -> False, ImageSize -> 1000]

How do I find the coordinates of points in this image? Or thinned = DeleteDuplicates[pts, EuclideanDistance[#1, #2] < 2 &] to keep it as data...? |

Using BarChart and pastel colors is there a method to get the labels to be the same color as the bar? At this point I'd like to register a small protest on behalf of people with less than perfect eyesight who will find rotated pastel-colored text difficult to read. Why not make the labels simple, straight, and readable, rather than 'interesting'?! OK, protest over... :) |

Baffling increase in runtime It might be just your computer... On my Mac OS X/Mathematica 9 system, I see a slowly rising trend from 80000 to 100000. |

Why this Wolfram summation gives indeterminate answer on their online interpreter? WolframAlpha questions (when not involving Mathematica) are generally considered off-topic for this site. Partly that's because no-one here knows what goes on inside WolframAlpha... :) |

Import specific data from Excel to make a plot @NikGkav In the case of the simple solution (mine), you should change the order of the first two lines inside the 'triplet construction list' in the Table function (i.e. the data[[1, column]] and data[[row, 1]]. Table should be one of the first Mathematica functions you study... For Mr.Wizard' answers, you can just flip the table (tbl = Transpose[tbl]) just after tbl = First@tbl; (I think...) |

QR Code in shopping cart handle @murta puzzled as to why horizontal distortion is necessary? You have to stand in one location - why not square on? |

Import specific data from Excel to make a plot I wonder how long ago it was since you were a beginning wizard (sorcerer's apprentice) - you're scarily good sometimes...:) |

Connect to SQLite database Useful answer - I wonder whether the OP will end up going the built-in SQLite route... |
