comment Why doesn't Quantity accept a Dynamic expression as a second argument?
@Algohi It depends on how you define works, because when you try to add two quantities, the result is not what one expects: Dynamic[Quantity[Dynamic[b], "feet"] + Quantity[1, "meters"]] Now try the same with a version where you remove the inner Dynamic.

comment Set conditions at a permutation
Are you sure you did your homework? A Permutation is per definition a rearrangement of members from a set. When your set {a,b,c,d,e} contains only one d, then there is no way it can ever have more than one d in all existing permutations. Can you clear what exactly you mean?

comment HoldForm gives tick labels in Plot without multiplication sign
@Pickett Yes, on OSX the key-bindings are different! I just gave the short key for Win and Linux. If you like, just edit my answer and include the key-binding for OSX.

@LCF hehe.. but who should have guessed that from your name? On the internet, everyone is a dude I guess :-)

comment HoldForm gives tick labels in Plot without multiplication sign
@LCF I have added an example on how to use it. Please, is it possible that you give a very small snippet of code where we see what you try to do?

Does my answer work for you too?

comment How to make a widget float?
But you have seen that the source of GUIKit` comes with your Mathematica installation and you even have all java sources available, yes?

comment How would I use Map on a Dataset column?
@GordonCoale Yes, it always felt a bit half-baken to me too and this is probably one reason why I haven't used it very often so far.

comment How would I use Map on a Dataset column?
Unfortunately, I have only 10.1 here. Can you tell me what this gives on your machine <|#|> &[<|"u" -> x, "v" -> y|>] or this here <|"u" -> x, <|"z" -> 1|>|>? If you cannot get this working, can you please poste a complete example that gives the error to e.g. hastebin.com and give the link here? Or you ask in the Mathematica Chat.

comment Removing a histogram's vertical edges
@MarcoB If you want to easily upload images, please have a look at the SE Tools package which has an easy-to-use palette to simply mark and upload images directly from within a notebook.

comment Equation solving problem
There are various reasons why people are sometimes unfriendly to new users that are not even able to learn the very basics of a new language they try to use. I have seen the comments in your other question. Why don't you try to read here and ensure that your next questions cannot easily be found there?

comment STL exports as flat rectangle
If people want to try your example, they won't be able because of the missing plotter variable. Can you try to create a small self-contained example, that shows the same behavior?

comment Open-source IntelliJ IDEA plugin to support Mathematica development
..Therefore, even if you could magically call the formatting engine on Mathematica input, the linebreaks that Mathematica used wouldn't be adjusted and the code would not look better. To make this useful, you would have to force some more rules (e.g. how a Module or a Block is broken into lines) but that would definitely annoy some users. Therefore, I left it pretty unspecific. But anyway, the current answer is no, it is not easily possibly to call the formatting engine.

comment Open-source IntelliJ IDEA plugin to support Mathematica development
Even if it could, it would currently make not much sense. The formatting engine of IDEA is very conservative: It doesn't insert linebreaks, it allows different formatting styles and it doesn't force the user to a specific style. Basically, the only thing I force is that linebreak inside a new [, (, or { forces one more indentation level, and unfinished expressions that are separated force a new continuation indent. I left it that unspecific because I have seen so many different formatting styles and I didn't want the users to have to change their own styles just because of the IDE...

comment Simplify on a structured array
Right and it is exactly what I meant by * simplify your expressions before you build your structured array*. Btw, please verify carefully whether the ParallelMap is really faster than simply calling FullSimplify on the complete expression.
