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.

@IgorRivin They see, but do not observe. The distinction is clear.

@RunnyKine Ijust cannot imagine that nobody at Wolfram saw this. Or do you think they do not read and check their own documentation?

comment StringCases is Confused with Patterns in Version 10.0.1
It's even red in the help. So maybe it is on purpose? If you do not want to see red things, just do StringCases["item13", {"item"~~x:DigitCharacter.. :> x}]

comment Running a Mathematica Notebook from command line and saving the output
@YvesKlett still you sometimes do want to run .nb files in the background. E.g. I could imagine that test files could be run in V10 and the reports be saved as HTML or some such and then it is easier to look at them.

comment Is garbage collection broken in version 10.0.0?
The interesting question is if 10.0.0 is more buggy than 9.0.0 was. I rarely use 10.0.0. Both kernel and FrontEnd are inferior to 9.0.1 (where comparable). Of course there are some exciting new features in 10, but I just wait for 10.0.1

comment Is this 30% slowdown in Mathematica 10 due to DownValues lookup time?
I also saw 70% under Linux. So maybe it is some of the external libraries (MKL?).
