@Nasser for me was the waste of point symbol for dot product instead of dot notation.

@Murta what is the difference between the point symbol and dot notation? You mean you think Dot[] should be used for matrix/vector multiplication? I am not sure I follow. In Matlab, * is used for matrix multiplication and .* for element wise multiplication.

speaking of notations, I find the new data set notation not good. <| ... |> too hard to read on the eye. They should have selected something better.

I feel like it must be the answer to a question somewhere.

I think possibly this should be reopened:

@Oxinabox Would you please consider posting a question tailored to and self-answer it with a description of and link to your project? Thanks!

@Mr.Wizard I am very cautious about creating a question like that. It seems self-serving, and people often take offense (and downvote) questions like that. -- it seems like self promotion.

@Nasser I mean, the "." symbol is used for Dot[]. It would be nice if it were used for access function values like f.valueA, f.valueB. Of course, this was a decision made 26 years ago.

@Oxinabox Unless I am missing something you are offering this project free of charge. As such it is a service to the community, not a self-serving advertisement. A single Q&A (rather than a barrage of them) should be welcomed by the community. See for example: mathematica.stackexchange.com/questions/16485, meta.mathematica.stackexchange.com/questions/5, meta.mathematica.stackexchange.com/q/1043/121.

Ok, I'll make a post like that in the morning

@Oxinabox Good. :-)

By the way it should be said that advertising a commercial product is not itself wrong either, but it is vital that the user be up-front about his commercial interest, and that it is only a facet of his participation here. (When every other answer refers to the author's product the community does not react well, and rightly so IMHO.)

@Oxinabox do you have some youtube on how yours Mathematica-Commandline-Interface works?

Can someone reproduce this? In V9 I have to run something with CuntryData and then query for CityData because if I run `CityData on fresh kernel then it returns $Failed.

@Kuba works fine for me (tested CityData["Berlin"])

@RolfMertig ehh, ok :P I have to live with this.

Thanks.

Or you clean the paclet directory. Or try in V10.

@RolfMertig the thing is I'm testing some differences between V10 and V9

And I could access CityData in V10 instantly.

@RolfMertig well, that's an inprovement, isn't it? :) I should be happy.

maybe student-license related issue.

@Kuba Do you have Preferences/System/System Settings "Create and maintain version specific front end preferences" checked?

@RolfMertig Yes.

@fairflow @fairflow no, sorry, it's all proprietary (invep.de/mathematik.html)

It there a simple reason why StringCases[{"a", "a1"}, "a" ~~ _] captures "a1" but FilterRules[{"a" -> 1, "a1" -> 2}, "a" ~~ _] misses it?

@bobthechemist because FilterRules performs ordinary pattern matching, not string patterns. If you want it to work you have to do something like:

  FilterRules[{"a" -> 1, "a1" -> 2}, x_?(StringMatchQ[#, "a" ~~ _] &)]

Great, thanks @kuba

@bobthechemist Your welcome :)

@Murta unfortunately not, my ,liscence has expired and it could be quiet a while before i am given a new one
