comment Why do I get Floor and Ceiling in my output despite my assumptions
@bills This is strange. Surely using the Assumptions option to Sum, setting the global $Assumptions and using Assuming should all have the same effect?

comment How to speed up band matrix-matrix multiplication?
What version are you using? With version 10 on Windows I get 1.75 secs for a.u and 1.2 secs for a2.u (but with an added overhead of 2.4 secs to calculate part)

I think only Wolfram Research can answer this.

comment Manipulate Parametric Plot
Check the documentation for ParametricPlot - the coordinates need to be in a list: ParametricPlot[{fx, fy}, {u, umin, umax}]

comment Coloring edges of a graph according to their weight?
Nice. I didn't realise you could use patterns in EdgeStyle. FYI you can use <-> for a slightly more readable UndirectedEdge.

comment CPU usage remains at 13% even after I quit the kernel
Mathematica.exe is the front end process, not the kernel (which is MathKernel.exe). It does sound like a bug though - does the CPU usage continue even after all notebooks are closed?

Good question. I was sure that one of vor["Properties"] would hold the answer but no luck...

comment On the order of rules specification
As I understand it, a pattern with a condition attached is considered more specific than one without, but in general there is no way to say that one condition test is more specific than another. How would you order x_/;blackbox1[x] and x_/;blackbox2[x]?

comment Unusual Slow Down with LocatorPane/DynamicModule
To be really helpful the code should be complete, ie someone should be able to copy and paste it into a Mathematica notebook and run it. This means including definitions for things like watershedMatrix - it doesn't have to be your actual data, some simple code to generate fake data will be just as good.

comment Rational display with Quantity
It looks like the formatting for reciprocal units comes from ToPerBox and ToSlashBox in CalculateScan`UnitScanner`Private.

comment Unusual Slow Down with LocatorPane/DynamicModule
Please focus on just one question, and try to strip your code down to a minimal example which demonstrates the problem and include the code.
