comment Pure function with attributes of arbitrary number of arguments: Is it possible?
@rm-rf: Yes. It's the first time I see an actual use for empty arguments; up to now I've only seen them as potential error source (due to an accidental extra comma).

Would it be an option to also rasterize your stationary object?

comment Why doesn't Mathematica evaluate this limit?
I guess the problem is that the ?NumericQ on DeltaAnalytic prevents Limit and Series from seeing the analytic formula.

comment Does `Eigenvalues` evaluate in a parallelized way?
However it has a natural followup question: Which Mathematica functions use thread-level parallelism?

comment Does `Eigenvalues` evaluate in a parallelized way?
The reason why top displays 100% four times is because there are four processes (namely subkernels) doing calculation using a single thread each. I guess the idea is that if you explicitly parallelize, you don't want Mathematica to interfere with your parallelization strategy.

Did you test that the Java code you're trying to port works on your system?

comment How to import non-text data from std input in a Mathematica script?
Actually if you call cat without any argument, it also copies stdin to stdout. So you can just omit the - and write img=Import["!cat","tiff"].

comment ClearAll[“Global`*”] stops working with Context set to 'unique to this Notebook'
@zhermes: I have no idea. IIRC the variables actually already start out being black when the notebook uses its own context (can't check now); no idea why. Maybe the colouring algorithm doesn't take the different context into account correctly.

comment How to pull scalars out of a function that should act on lists?
@janitor048: Sorry for the late reply, I hadn't been on the site for quite some time. Something like f[a_, b_+c_]:=f[a,b]+f[a,c] (as additional definition for f) would probably do what you want (it would, however, distribute all sums, including those not covered by the above rule afterwards; this may or may not be what you want).

comment Nested definition: How can I define a function with a passed-in expression?
@Mr.Wizard: Unfortunately I don't remember what governed my decision back then; it might have been because ruebenko not only solved my problem, but also pointed out a weakness of my original interface and improved upon it. But since I don't remember the reason, all I can do is to guess. I had definitely seen both back then, because I had upvoted both.
