Clipboard with transparency What program are you trying to paste into? |

Montgomery Modular Exponentiation You could probably do some trick like representing it as a list of integers to get it to compile, but I don't know if that overhead would be more or less than the benefit you would get from compiling. |

Montgomery Modular Exponentiation You have to be careful though because Compile expects machine-sized integers in most places. You'd need to use an alternate representation. |

Montgomery Modular Exponentiation Look into Compile with CompilationTarget-> "C". |

Approximately Fit Data Without FindFit Very nice! Can you explain what you mean by "the relative weight of the penalty"? |

Approximately Fit Data Without FindFit I'm on v7 with access to v8, so no LowpassFilter. My original idea was actually something similar to MovingAverage. Unfortunately the Mathematica implementation of MovingAverage clobbers a value (maybe more than one?) each time. I ported the Matlab version of moving average and Nested it around 10 times with a window of 5. I wasn't happy with this solution, which is why I asked the question. |

Approximately Fit Data Without FindFit Clever idea! Unfortunately when I tried plotting the derivative of the interpolation function of the filtered data, it was a total mess. It oscillated like crazy. |

Poor anti-aliasing in Rotated text with ClearType on Try rasterizing it ( Rasterize[Rotate[x, # \[Degree]]] & /@ {90, 90.1, -90, 85, 95, 45, 0}). Same problem, right? Now zoom in to 200% or 300%. The 90 and 90.1 use the sub-pixel rendering so have discolorations on the edges while all the rest use standard grayscale anti-aliasing. |

Poor anti-aliasing in Rotated text with ClearType on I get the same problem with Mathematica 8 on Windows 7. |

Use Mathematica as a terminal You can call external programs with Run[] and RunThrough[] but I don't think they can work interactively. |

Solve pair of recurrence relations I'm not sure about "should" but it doesn't seem able to. Mathematica 7 actually gives a closed form expression for the recurrence relation that only involves B[k], but it evaluates to Indeterminate for every value I've tried. |

Solve pair of recurrence relations I've tried fitting some models to it and I have gotten very close, but I haven't found a closed form function. |

Solve pair of recurrence relations @lip1 This is a function of n in the Mathematica sense. Do you mean a mathematical function, like a closed form expression? |
