Q: What's tricky about output-formatting?

b3m2a1So as part of my mucking about with the StackExchange API I decided to check what kind of questions high-rep people tend to ask. I pulled in all the question data and then took the rep of the user asking each question and grouped those by the question tags: $reputationTags = GroupBy[ Flatt...

Q: Can I ask a question about what people think about mathematica rather than a technical question?

StarBucKI wondered if it is appropriate to ask on mathematica stack exchange a question about what they think about the ergonomy of mathematica in comparison to other softwars (matlab etc). Because I find mathematica very unfriendly in comparison of everything I learnt but I would have to have other poi...

<|"col1" -> 1, "col2" -> 2|>
I want change "col1" into "a" and "col2" into "b"
So I write this code.
<|"col1" -> 1, "col2" -> 2|>[<|"a" -> "col1", "b" -> "col2"|>]
but it doesn't work.Can anybody give some help?
I have a exmaple in documentation,so I don't think I make any error..

@yode this is documentation of Dataset, if you need that you need to use Query: 
<|"col1" -> 1, "col2" -> 2|> //      Query[<|"a" -> "col1", "b" -> "col2"|>]

Normal[Dataset[<|"col1" -> 1, "col2" -> 2|>][<|"a" -> "col1",
"b" -> "col2"|>]]
@Kuba Thanks. :)

@yode does KeyMap[Replace[{"col1"->"a","col2"->"b"}]]@assoc do what you want?

On a completely unrelated topic, I'd like to check if my idea makes sense: 1. As of 2017, it is still not possible to delete GitHub issues, 2. I implemented an automatic reporter to create GitHub issues for the IntelliJ plugin when the user experienced an exception.
To prevent my main issue list to be spammed with auto-generated issues, I set up a fake account and I will set up another fake repo for auto-generated issues of the plugin.
Does anyone see a problem with this? I don't, but I wanted to make sure.
