I've been a user of Mathematica since version 2.2. I am a physicist by training and engineer by trade, and a bit of a poster child for engineering applications of Mathematica. The other M product people look at me funny but are secretly jealous.

comment Incompatible Changes since Mathematica Version 7?
@Szabolcs The original report was filed online, I did not keep a copy. Below is a copy of the reply from support: Thanks for contacting Wolfram Technical Support. Regarding the issue you reported, it seems this is an intentional design change. We have internal discussions on this and the argument from the developer is that "Setting $Context to $System on subkernels is necessary to make sure (new) system symbols arrive in the correct context on subkernels, because despite the MathLinkPrintFullSymbolName settings, system symbols do not have their context attached".

comment Incompatible Changes since Mathematica Version 7?
@Mr.Wizard Thanks for letting me know. I was not aware of circumstances where I could edit someone else's post. Also, it seemed presumptuous for me to edit your post. Should I just copy/paste the comment into the post as it is?

comment Incompatible Changes since Mathematica Version 7?
I can't edit Mr. Wizard's answer, so he is welcome to add this to his list at his discretion. In version 9, expressions evaluated in parallel default to the Global context. In version 10, expressions evaluated in parallel default to System. This causes shadowing when using ParallelNeeds on packages which are supposed to define global symbols, and leaks symbols into the System context. This has been confirmed by Wolfram support as a design decision, not a bug.

comment Best practice of passing a large number of parameters to functions
For completeness, the one-liner Plot[PDF[LogNormalDistribution[#mu, #sigma], x], {x, #lb, #ub}] &[par] works.

comment Is there an equivalent of Sum for And?
In version 10, the function AllTrue will do this documentation. It even short-cuts.

comment Entering scientific notation in an InputField
Thanks to everybody for their help. I am not quite ready to attack creating my own control type, so I will study these approaches carefully. I selected this answer because it gives the option of entering the number in normal notation as well as scientific.

comment Entering scientific notation in an InputField
I know this is kind of a weak question since I have already found a workaround, but I wanted to get this behavior documented here as it seems buggy to me.

comment Calling MATLAB from Mathematica
I am using MATLink to drive the Data Acquisition Toolbox on a test system I am developing. I would rather work entirely in Mathematica, but a) I don't believe there is a straightforward way to operate data acquisition systems from Mathematica and b) this approach lets me recycle another engineer's MATLAB code and get up to speed faster. Thanks for the package.

comment Why can I still hear sound when the frequency of the periodic function inside Play is lower than the range of human ear?
oops, that was supposed to be a comment. Too early in the morning to be posting.
