@gwr I've seen that too. When the font is italic is almost impossible to place the cursor in the correct location.

I cant say for sure it ever had that disclaimer. I just know that it's an older "forum" for Mathematica questions.

@user82663 perhaps the web-based version is a possibility? (i.e. Wolfram|One or Mathematica Online)

@lonestudent I see no reason there should be a "nice number" answer, and of course there isn't just one answer.

@Szabolcs, I don't think it's just you. In fact, I don't think its even M.SE specific. In general Q&A sites have hit the wall.

I believe Region[RegularPolygon[6]] should work, but also functions like Area should work on Polygon already.

@MichaelHale That is quite impressive. I'd love to see his notebook in action.

If you want to keep it a `Graphics`, this function might be useful:
drainColor[g_Graphics]:= g/.c_RGBColor:> ColorConvert[c,"Grayscale"]

ds[All, Norm[{#x, #y, #z}] &]?
chuy
Apr 27, 2020 21:54
You could do something like:

ParametricPlot[Evaluate@Tuples[x/.{Solve[x^2==u,x],Solve[-2x^2+3==u,x]}],{u,0,10}]

ReplacePart[list, {_, 2} -> {x, y}]? I suspect I am missing something
chuy
Oct 15, 2019 14:22
probably best to keep that in a Module
chuy
Oct 15, 2019 14:21
very true!
chuy
Oct 15, 2019 14:20
@Szabolcs Yes, maybe something like dataset[All, {"a" -> ( #/Once[dataset[Norm, "a"]] &)}] then?
chuy
Oct 15, 2019 14:19
@Szabolcs I have used: dataset[All, <|#, "d" -> (Total[#c]/#a)|> &].
chuy
Oct 15, 2019 14:15
@Szabolcs dataset[All, {"a" -> ( #/dataset[Norm, "a"] &)}] maybe? That's what I have used in the past.

it's my naive semantic web
chuy
May 3, 2019 19:11
or any Entity + Property
chuy
May 3, 2019 19:11
in principle, one could have any entity listed there, you can swap Spain with Portugal
chuy
May 3, 2019 19:10
I have stuff like this :wolframcloud.com/objects/jhernandez/kb/Country/Spain/Population
chuy
May 3, 2019 19:08

@CarlLange thanks an example here is very useful for me
chuy
May 3, 2019 18:53
yeah something like that, could even start with something simpler (tabular data)
chuy
May 3, 2019 18:50
Is there a straightforward(ish) way to push a dataset (or group of associations) to an RDF Dataset (maybe this question doesn't even make sense)
chuy
May 3, 2019 18:48
I think there is an interesting set of opportunities if one could use SPARQL to access Entities (especially in conjunction with other knowlegde graphs).
chuy
May 3, 2019 18:42
Would you expect this to work?
SPARQLSelect[
RDFTriple[{SPARQLVariable["country"],
EntityProperty["Country", "Name"],
SPARQLVariable["countryName"]}]][
EntityList@EntityClass["Country", "GroupOf8"]]
chuy
May 1, 2019 16:31
What would be the advantage then? I guess I haven't seen an example where this seems useful (yet).
