Being a trained physicist I learned Mathematica while developing FeynCalc in 1990. Since then I am stuck with Matheamtica. I do like some other programming languages like Fortran and Java.

I work at my own company, GluonVision GmbH, in Berlin, doing mostly (web)Mathematica related consulting and projects.

Lately I became more and more insterested in CDF projects.

comment Bug in ArcLength?
The bug is actually in RegionMeasure. Try RegionMeasure[Line[{{0, 0}, {1, 0}, {2., 0}}], 1] and RegionMeasure[Line[{{0, 0}, {1, 0}, {2, 0}}], 1]

comment Creating REST Web Service with webMathematica
There is webMathematica/WEB-INF/Applications/WebServicesServer/Rest.m, but I have no idea how it works. There seems to be a "REST-like" interface over at WA, and WA is somehow based on webMathematica, so it seems possible. Maybe WA people are reading this and have pity with good old webMathematica users?

comment Is it possible to move .mx file from one server to other?
@ybeltukov Since Mathematica 10 it is possible to move .mx files fom one server to the other, also from Windows to Linux etc.

comment Customize keybindings without modifying files in the installation directory
Or, suppose you want to stack windows (not possible in V10.0.2 on Linux at all): just put FrontEndTokenExecute["StackWindows"] in joker.m, hit Ctrl S (to save it; possibly followed by Ctrl W to close it), and then Ctrl T stacks them again.

comment Linux: Mathematica crashes when clicking documentation links very fast
M10.0.2 Debian 7 with OpenBox windowmanager also gets crashed after around 40 fast clicks.

comment Customize keybindings without modifying files in the installation directory
@Mr.Wizard Well, you can change what Ctrl T does. Either it evaluates (myInitVar=12;) or does something else. Whatever. And you can change it on the fly: Just hit Ctrl R : this opens joker.m in the FrontEnd. You uncomment an example or add whatever you like. Save it. Then, without restarting the FrontEnd you have redifined what Ctrl T does. That is like a joker (keyboard shortcut), isn't it?

comment Mathematica 10 crashes when kernel is quit from MenuItem
@Mr.Wizard And I commented there that his solution crashes Mathematica 10 ... That was my main motivation to hack keyboard shortcuts again.

comment Mathematica 10 crashes when kernel is quit from MenuItem
@Mr.Wizard Sure, but that is not the same: it asks you if you want to quit. I do not want to get asked ...

comment Customize keybindings without modifying files in the installation directory
@belisarius De nada! I was just too much annoyed that some of my old shortcuts crashed Mathematica 10. Should I twitter the installation line?

This idea of putting a modified copy in the tight location was mentioned already some time ago by @rm-rf I think.

comment How to code around known MMa special-case failures?
@Scabolcy Did you try FriCAS or Open-Axiom? Axiom ( aka ScratchPad) had a clean type design (theoretically; in practice it is quite hard to get anything non-purely mathematical done).
