How is AstronomicalData interpreting its date arguments? I would be interested in your SPA implementation. Would you be willing to share? |

Does Mathematica support collaborative filtering and recommendation systems? As it is, this is a very vague question. Maybe you should be more specific about what you are looking for or what Problem you are trying to solve. |

How to make plot with frame and two different scales on the x-axis (CMB power spectrum example) I think the questions aims at the changing log scale of the bottom x-axis. |

Applying TextRecognize on alpha-numerical table @belisarius Brilliant! Working like a charm (with some manual tweaking still to do). Is there an easy way to automatically determine the number of table lines in the figure, or do I have to count manually and modify the code accordingly? |

Do you know of any web-based university course that is entirely Mathematica based? I gave a course on Mathematica as a tool for astronomy and physics completely done in form of Mathematica notebooks. |

Histogram: Bars not stacked, not overlapped, but side by side? @MockupDungeon There are always more ways to come up with some hand-woven solution :) |

Plotting Error Bars on a Log Scale @AnastasiiaAnishchenko Hmm, I don't get this error. Have you installed the package? Here is the [link]( library.wolfram.com/infocenter/MathSource/6747) . Download the zip file and install it, then retry the Needs command. |

Plotting Error Bars on a Log Scale @AnastasiiaAnishchenko Just write Needs["ErrorBarLogPlots`"]. |

Solve an equation in $\mathbb{R}^+$ @FormlessCloud I updated the answer to show how to get rid of the braces. |

Custom arrow shaft Agreed, that's cool. But imagine adding a few vertices, which would requires a lot of fiddling around with Transformations to have the Arrows where they belong. It would be nicer to let Graph do this. But still, very nice idea! +1 |

How do I compute sidereal time and JD? Great! A pity that I can't give you another +1 for each edit :) |

Fast Spherical Harmonics radiative transfer @Heike Wow, 3.5 vs. 148.5 seconds. Thank you for the tip. |

Fast Spherical Harmonics radiative transfer @J.M. LinearAlgebraMatrixConditionNumber[Table[B[i, m]...` gives 2.63531*10^98 . My comment on the N[#,30] was to remind me that even with N the LinearSolve::luc error occured and that I had to use SetPrecision[#,Infintiy] to get rid of it. |

Fast Spherical Harmonics radiative transfer @J.M. Neat! Unfortunately, this is no bottleneck. Still nice to know, thanks. |
