Being a trained physicist I learned Mathematica while developing FeynCalc. Since then I am stuck with Matheamtica. I do like some other programming languages like Fortran and Java.
I have my own company, GluonVision GmbH, in Berlin, doing mostly (web)Mathematica related consulting and projects.
Lately I became more and more insterested in CDF.

Unable to copy/paste CDF embed code in Ubuntu Did you try CDFInformation and CDFDeploy? Why use a a pop-up window anyway? |

Can one identify the design patterns of Mathematica? Memoization by itself is a very important design pattern in Matheamtica: used in the right way I could get amazing speed-ups for real-world consulting projects over the years. Lately I used transformation of held expressions to transfrom f \[RightTeeArrow] (2 x) (which displays nicely in a notebook) to f[x_]:=f[x]=(2 x), where the independent variables need to be explicitly specified. Now, if only I could control the precedences of the mysterioius FrontEnd's parsing ... (but this is not so serious, just put () around the right hand side). |

Anything wrong with Atlas 2 or Mathematica? @Verbeia: the links work for me. But still the question if too localized and one needs the proprietary Atlas 2 packages. |

Put webMathematica folder outside Tomcat webapps folder? Did you try a symbolic link? |

webMathematica interface for Mobile apps webMathematica is completely independent of Wolfram|Alpha. Please read this, and, if you are entitled, get the webMathematica amateur yourself, study it for a few weeks or months, and then you see how it all works. |

How can I solve this nonlinear system with 3 equations and 3 unknown? The syntax is Solve[eqs,{p,q,j}], but it seems too hard as it stands. Do you have further restrictions like g being integer or alike? |

float output left in CDF Maybe you could just specify another PlotRange such that the x-axis goes up to 300 or so? |

FeynCalc “May shadow or be shadowed by other definitions” The next time you start FeynCalc (if you do not want to use FeynArts and Tarcer and Phi you can speed things up by executing first $LoadPhi=$LoadTARCER = $LoadPhi = False; followed by Needs["HighEnergyPhysicsFeynCalc`"];) and then try to run some examples, e.g., from here or you can try some of the .m or .nb files from the fcexamples subdirectory from HighEnergyPhysics (though some will not work unfortunately right now) |

FeynCalc “May shadow or be shadowed by other definitions” Just try to delete the directory HighEnergyPhysics, unzip fc820.zip again and run the answer again.This should work. |

How can I fix Mathematica's text line-breaking algorithm not to line-break so soon? @Verbeia did you ask support@wolfram.com ? If you get an answer, please post it here. |

How can I fix Mathematica's text line-breaking algorithm not to line-break so soon? @rcollyer I don't know either. The CellPrint makes it hard to add into Grid. I tried for 10 minutest then I gave up (to make a JPG from the generated cell). Maybe the best is to just forget about the (known) insufficient line-breaking and table-formatting capabilities of Mathematica and use LaTeX and get the result as an image or some such. Too cumbersome to bother really. |

How can I fix Mathematica's text line-breaking algorithm not to line-break so soon? But should it not look like the result of Cell["This is a test footnote that is designed to go over several
lines and demonstrate the crappy line-breaking algorithm. This might or might not be long enough. We shall see. ",
Hyphenation -> True, TextJustification -> 1,
CellMargins -> {{400, 400}, {1, 1}}] // CellPrint |

Determine the Number of Lines in a Text File +1 very nice. It is roughly 10 times faster than CountLines, but 10 times slower than using wc. Maybe you could add NullRecords -> True such that the results agree. |
