My answer formats properly in the edit preview, but not in my browsers (Safari, Chrome on Mac). Any idea why "tensor" appears with asterisks and not in italics?
 
@MichaelE2 I fixed it for you. SE's markdown requires a space after a *. In other words, you can't style a substring of a string. I think the different view in the preview might be because it uses a slightly different markdown parser.
If you want to use latex there, might as well go all the way with: $\mathtt{TensorProduct}[tensor_1, tensor_2,\ldots]$ :)

@rm-rf Thanks.

These kinds of color reproduction questions make me despair, as I try to think of them first through physically accurate modelling:

Q: Adjusting Density Plot Color Function for Diffraction Simulation

John SmithI'm trying to simulate Fraunhofer diffraction by a single slit using DensityPlot I run the code: DensityPlot[(Sinc[β])^2, {β, -6 π, 6 π}, {y, -6 π, 6 π}, PlotPoints -> 200, ColorFunction -> GrayLevel, AspectRatio -> 9/16, Frame :> False] and get: Which is great but I'd like ...

First of all, the color is well outside sRGB gamut. Secondly, white on the photo is a sensor artifact. Thirdly, color space handling and spectral colors in Mathematica leave lot to be desired. Lastly, when playing with linear intensities, one has to manually manage gamma correction, which is poorly implied for Mathematica graphics.

@Mr.Wizard Are you still on Mathematica 7? Could you please tell me what are the attributes of Locked?

@IstvánZachar In this version Locked was not Locked.
Even in version 8 Locked was only Protected
 
12:57 PM
@halirutan Yes, I expected that, thanks! In v9 it is finally Locked.
 
@IstvánZachar No more easy hacking.
 
@halirutan Actually, I never had any programming problems that involved such hacks. The cause of my question was this thread on SO, and the findings I dug up.
There does exist a very dirty hack though...
 
@IstvánZachar We had kind of the same discussion here and decided to delete it completely because for the obvious reason that people earn their money by selling packages that they need to secure.
 
1:27 PM
@halirutan Sure, I anticipated something like that, and I can understand completely.
When did this discussion take place?
 
@IstvánZachar Give me a sec
@IstvánZachar Istvan, do you have enough reputation to watch deleted posts?
 
I think so
 
Then take a look at the comments in this answer
We moved the discussion to email after a while.
 
Thanks! Now I remember reading this last year...
