An easier and more efficient way to combine lists? @kale could you say how fast is Array in your setup? |

MathKernel and MathLM interaction @Searke it contradicts my observations. It happened to me few times (two times I guess) that I lost part of my work some time after the crash of the server running MathLM. But in all these cases I was working in the frontend, not in pure MathKernel. |

Is there an equivalent of MATLAB's Workspace window in Mathematica? You might be interested in this Stack Overflow question: Profiling memory usage in Mathematica and especially the answer by Alexey Popkov. |

Simplify Binomial Function It is interesting, that Simplify[Binomial[n, k]/Binomial[n, 1 + k], ComplexityFunction -> f] with your definition for f gives Binomial[n, k]/Binomial[n, 1 + k]. It looks like Simplify does not try enough transformations of Binomial. |

generating pdf using UseFrontEnd welll it seems you don't need the UsingFrontEnd command to plot = Plot[x^2,{x,-2,2}] and Export["/home/username/output.jpg",plot]. The reference says that UsingFrontEnd is neccesary for NotebookWrite[] and similar functions (I have used it to NotebookPrint[] some time ago). |

Eigensystem, Eigenvalue doesn't output nonreal eigenvalues @jak N @ Eigenvalues @ F is the same as N[ Eigenvalues[ F ] ] and the same as F // Eigenvalues // N. So these are the three ways of using functions on some arguments. |

Problem overloading D[] using UpValues OK, I can do D[#, r] & /@ (r + ftest[r, r^2]), but this is not the solution I hope for, I want to make creation of Derivative[_,_][ftest][_,_] not possible for D[] |

Problem overloading D[] using UpValues @Mr.Wizard I expect the result to be 1 + ftest[1, 2r], just as J.M. wrote |
