How to create internally optimized expression for computing with high WorkingPrecision? performing arithmetic operations in the right way can reduce round off errors. One important example is use of HornerForm (a built in function) for computing polynomials. Most text books on numerical methods show a few other tricks for specific cases. It's all about avoiding catastrophic cancelation, which is the loss of precision due to subtracting numbers that are nearly equal but not close to zero. |

How to create internally optimized expression for computing with high WorkingPrecision? It might work better if you make jacobianMatrix a CompiledFunction. That will help if FindMinimum uses MachinePrecision to get close to the optimal solution, and switch to higher precision for fine tuning. |

ListPlot and Union related question Back when I was in school, I did my homework myself. It's too bad the OP doesn't feel like thinking about this, because they can't learn much by copying code somebody else wrote. |

What are the use cases for different scoping constructs? Yet another scoping construct that I didn't see mentioned is DynamicModule. |

Interactive steam tables and phase diagrams in Mathematica For years I have wondered why Wolfram hasn't included each steam table as an InterpolatingFunction. |

A good way to manage code in a complicated CDF? I saw SaveDefinitions before, but couldn't remember what it's called. I think that's the solution to my problem. Although I haven't had a chance to try it. I would accept it as an answer if you entered your comment as an answer. |

Creating a Tooltip that knows what platform is currently being used This is the best criteria to use. However, failure to use Dynamic (See RM's solution) is real cause of my problem. |

Compiled version of (Norm/@coordinates) Silly me, I checked the list of compileable functions and didn't see it. I also didn't know about Internal`Square. |
