Having used Mathematica as a “gateway” language, where to from here? Mathematica has tried to capture some Perl mojo with its regular expression capabilities, and one can write pretty opaque code in Mathematica too, so I can see the overlap... |

Having used Mathematica as a “gateway” language, where to from here? I upvoted this because one has to know at least one non-commercial language in order to be more independent and mobile. |

Having used Mathematica as a “gateway” language, where to from here? Nice overview (+1), agree on the importance of Javascript. But Python is still my favorite technology integrator. And you forgot to address how best to learn Do loops... (fortunately). |

Having used Mathematica as a “gateway” language, where to from here? @LeonidShifrin "do more powerful things..." - what things? Anyway, since you've obviously invested a lot of time in the answer, I won't insist one way or the other. |

Having used Mathematica as a “gateway” language, where to from here? I honestly think this isn't answerable in a definite way. |

Visualizing vector spherical harmonics @QuantumDot Thanks for the bounty! I'll get back to the field line issues in the next day or so... |

How to type a capital 'E' in Mathematica 9 using 'ToExpression' and 'TeXForm'? Thanks - I was actually wrong about requiring \text{} wrappers. It works without that, so it's a little simpler than I wrote at first. |

Visualizing vector-spherical waves I've worked around the error message in version 9 by perturbing the initial points for the field lines. I also know what could be changed in the field line plotting function to avoid the error - but I'll make those changes later... hope the example works properly now. |

How can I convert a plot to pdf or eps without errors? @Mechanicalsnail It worked out of the box. The linux server isn't under my control, so I'm not sure about the font related details of the Mathematica installation. |

Visualizing vector-spherical waves You're right, I see this in version 9, too. Not in version 8 - but it suggests that I have to catch some NDSolve failure... hopefully I can fix that soon (maybe not today, though). |

How to type a capital 'E' in Mathematica 9 using 'ToExpression' and 'TeXForm'? As to the reversed order: use the third argument to TexForm as I mention in the second link above: ToExpression["U = mc^2", TeXForm, HoldForm]. I used a letter U that doesn't have a built-in meaning. |

How to type a capital 'E' in Mathematica 9 using 'ToExpression' and 'TeXForm'? In addition to the above link, I just remembered an extended version of the same answer that I posted later. |

How to type a capital 'E' in Mathematica 9 using 'ToExpression' and 'TeXForm'? The general topic of your question is addressed in this other question: Unable to convert TeX input into mathematica. The specific case of the letter E is addressed in ogerard's answer. |

How can I convert a plot to pdf or eps without errors? I tried it on a Linux server with version 8 and could not reproduce the problem. The output of Export["p.pdf",%] looks identical to that in the notebook. I don't have version 9 on Linux, so I can't check any further, unfortunately. |

How can I convert a plot to pdf or eps without errors? I've added your images. Could you please include the code to reproduce the plots? See the help page for how to format code. |

Cannot solve system of linear equation sums? I just tried my LinearSolve idea and again can't get it to work in version 9 while it works in 8. See my edit. |

Cannot solve system of linear equation sums? I added my version of the code to the question to make it easier to reproduce. |

Nontrivial solutions of equation Try to do it by hand and see if you can get a smaller answer, without knowing anything about the matrix coefficients and $\lambda$. |

Doing vector manipulations on Mathematica Those aren't vectors at all. The contain vectors, but they're scalars. What do you mean by "manipulate"? Surely not Manipulate, but what exactly? |
