comment SetOptions for CoordinatesToolOptions for DateListPlot?
@Mr.Wizard Use SetOptions[ DateListPlot, PlotLegends -> Automatic] then simply plot two TimeSeries by DateListPlot[TimeSeries @@@ {{{1, 2, 3}, {1}}, {{3, 4, 5}, {1}}}]. Result: No legends, but if you add the options directly they will be plotted.

@Mr.Wizard you might also remove the CoordinatesToolOptions constraint in the title? The issue seems to be broader if something like PlotLegends does not work in SetOptions, doesn't it?

comment SetOptions for CoordinatesToolOptions for DateListPlot?
SetOptions[DateListPlot, ... ] still does not work properly in 10.2 -- I tried PlotLegends -> Automatic and it is not working.

comment Mesh Problems with MatrixPlot
+1. That is of course a very concise explanation of what is going on behind the scenes. Great.

comment Setting and changing MetaInformation for arbitrary objects
To make this more general I would suggest to use the information contained in the first part of the TemporalData object. For example, addMetaInformation[ td_, metarules_ ] := Which[ td[[1]] === TimeSeries, TimeSeries[ td, MetaInformation -> metarules], ...=== EventSeries, EventSeries[...], True, TemporalData[ td, MetaInformation -> metarules ]. Also one might define addMetaInformation[ td_, None] := td /. (MetaInformation -> _) :> Sequence[].

comment Data interpolation and ListContourPlot
Isn't this what Kriging is all about? How do the solutions relate to that concept?

comment Dataset vs an association of associations
+1. Very helpful answer that seems to explain why I do have trouble putting TimeSeries and EventSeries in Dataset. It seems to work but I do get interpretation warnings and the Objects are displayed with a red frame. Maybe better to put the information in a List then apply the needed Head after extraction?

comment Dataset vs an association of associations
I am not sure about internal intricacies and performance aspects but the Dataset to me simply is a generalization of what can be built using List and Association: You can have a Dataset to be a List of Lists or an Association of Associations - that kind of flexibility is absent with Association. So I use Dataset whenever I think of a complete set of data (eg. like a database), while Association is a building block and thus on a slightly lower level of abstraction.

comment Importing Excel Spreadsheet containing Array Formulas
I just received an answer from WRI technical support: The issue is known and they hope it will be fixed by a future release. Hope dies last as they say.

comment Importing Excel Spreadsheet containing Array Formulas
This bug is still present in 10.1. Any chance to get fixed in 10.2 ?

comment Is FrameTicks broken in 10.1.0?
I would say that rcollyer has provided a convincing argumentation -- somtimes "things change" and we simple humans have to adapt and break with dear habits. ;-) In any case I would suggest to remove the bug tag because Mathematica does behave according to its current documentation.

comment Mathematica learning resource dealing with bayesian inference
+1. Much needed advice since one has to really look hard to find something. There is also the Mathematica Navigator.

comment How to define an expression which is differently evaluated in calculations and printed
+1. Nice collection; I tried to use Format[ nearZero[ val_] ] together with Interpretation but that does not work out as nicely. It really seems to be about "to hold or not to hold".

comment Is there any Mathematica functionality enabling its use for the blind?
Is reading out really helping a blind person? Wouldn't they want to "read" code like on an Refreshable Braille Display? So maybe somekind of BrailleForm would be a start next to Speak?

comment Draw from a given list according to empirical distribution
A couple of data samples and maybe initial attempts would improve the question.

+1. Great to be reminded for what use case Outer was conceived of.

comment How convert list of numbers to list of points on x-axis?
That is why I sometimes go for the named function as it is so close to mathematics. While beatifully compact I do find other solutions quite unfortunate with regard to transparency and ease of understanding.

comment How convert list of numbers to list of points on x-axis?
I did with 1 Mio random numbers in the vector and the pure function was faster by around 25 % though in absolute duration that did maybe not matter that much (around .13 secs for my machine for the Thread-sokution).

comment How convert list of numbers to list of points on x-axis?
+1. Thread certainly is a beautiful solution. Nevertheless the performance advantage of a pure function seems hard to beat?
