comment How can I programmatically specify the positioning of a window at the time of its creation?

comment How to get grid lines at all (log) tick marks in Version 10?
That would indeed be very nice. There are so many new finance related charting functions etc., but no progress in actual scientific plotting.

comment How to get grid lines at all (log) tick marks in Version 10?
The problem is that hard-coded grid lines have to be adjusted manually for every individual plot.

comment Is the use of Block to temporarily override definitions inherently unsafe?
Right, that does happen in version 8, too. It's indeed a duplicate. So this doesn't explain my current v. 10 issues with inputs suddenly becoming "unevaluated" - I haven't even been able to isolate it enough to ask a question about it... very frustrating, it's some Dynamic thing.

comment Is Wolfram Language suitable for building web applications?
I agree with @JacobAkkerboom, however it is not clear what specific problem you want us to address. The example in your post does not show any Mathematica related issue.

comment How to get the new font in Mathematica 10?
One of the reasons I like this StackExchange site is that it allows (indeed encourages) users to enter code in blocks that are formatted as fixed-width with nice highlighting. As soon as someone forgets to do this, I find the code much harder to read. Similarly in papers when code is typed as regular text (to see what I mean, wrap any Mathematica code in TraditionaForm@HoldForm. In fact, TraditionalForm is already available as a means of getting proportional spacing, so why the need to fix InputForm if it ain't broken?

comment How can estimate the PSF function to deblur an image of plate licence of a car
The example image is clearly limited by the image resolution (pixelation) and not by the point spread function of the camera. So it's pretty hopeless. There is a Wolfram Blog post about this topic.

comment PlotLegends question
(+1) Looking forward to trying it, especially to see legending and general scientific plotting. I'm especially curious whether tick marks can be customized more easily (perhaps with themes, or at least in interactive post-processing). That's just one of my eternal unresolved complaints.

In the movies, they just say: "computer: enhance!" If that doesn't work, it would be good to provide more detail in your question, e.g., an example image and what else you have tried.

comment Constrain Fit to make a fit that remains positive over the range of my independent variable
@user16104 Whenever you do data fitting, you have to have some model that agrees with your underlying understanding of the data. In your case this is positivity. But there are infinitely many different models one could choose, and I think it should be up to you modify Alexei's answer to accommodate any other expectations you might have.

comment How to find all data points within closed curve
You're probably right, but I wanted to be as short as possible - that's what Algohi asked for, right? I guess it depends on whether the plot was considered to be already given or not...

comment Defining the Moyal Product in Mathematica
@Karan I think if what you really want is for the star product to keep its defining properties, then either your limiting approach in the earlier comment or brute-force ignoring of the conditional expression should be permitted. The last update to my answer should also do the trick.

comment Defining the Moyal Product in Mathematica
@Karan OK - ConditionalExpressions are of course also a warning for you to stop and think about the validity of what you're doing... basically the order of integrations seems to matter, and boundary terms could be cropping up in partial integrations. I think that goes beyond what the question asked for. But I could post a brute-force fix for this issue anyway.

comment Defining the Moyal Product in Mathematica
@Karan Yes, I think you're right - I checked again and 9.0.1 isn't working for the star[1/x^2,p] case because it can't do the FT. But in any case, that's a very pathological kind of function, so I'm not totally sure it's a real bug. Are you perhaps doing something in polar coordinates? Then the phase space integral has to be done differently, including the proper Jacobian. So the naive star product definition may not be what you need anyway.

comment Using NDSolve to solve Equation of Motion in cylindrical coordinates
If you're not sure what the correct expression for the canonically conjugate momentum is, write down the Lagrangian in Cartesian coordinates, make the coordinate transformation, and then obtain the momentum from $p_r \equiv \partial{L}/\partial{\dot r}$.
