[Cross-posted on StackExchange](https://mathematica.stackexchange.com/q/162952/12) ---- Consider the following graph with the vertex property "foo". g = Graph[{{1, 2}, {3, 4}}, {{1, 2} {3, 4}}, Properties -> {{1, 2} -> {"foo"...
Mathematica provides access to a huge amount of curated data. But most of this is so slow and so inconvenient to retrieve that it is literally next to useless. Take this simple query as an example: t = AbsoluteTime[]; Entity["Plant",...
[*Cross-posted on Mathematica.SE*](https://mathematica.stackexchange.com/q/162386/12) ---- I have a Mathematica application that consists of two sub-packages, corresponding to the contexts foo  (foo.m) and foob  (b.m). Some of...
I am looking for *the fastest possible* way to obtain the edge list of a graph as a packed array, represented using vertex indices (not vertex names). This is to construct a representation of the graph that is easy to handle in C code (through...
I am looking for a package that can do hierarchical clustering and plot publication quality dendrograms. The following should be supported at a minimum: - Provide a (symbolic) representation of dendrograms. - Operations on dendrograms: cut...
*[This was already asked on M.SE](https://mathematica.stackexchange.com/q/155932/12)* ---- I have [a Mathematica package][1] which uses a custom documentation page that is not built from source notebooks using Wolfram Workbench. [Such doc...
ExternalEvaluate, introduced in M11.2, is a nice initiative. It enables limited communication with multiple languages, including Python, and appears to be designed to be relatively easily extensible (see ExternalEvaluateAddHeuristic if you...
Has anyone gotten ExternalEvaluate to work with Anaconda Python on OS X? It used to work for me in the prerelease, but it's not working in the final release. In[2]:= py = StartExternalSession["Python"] Out[2]=...
*[Cross posted from M.SE](https://mathematica.stackexchange.com/q/155251/12)* ---- We can use [GeoServer](http://reference.wolfram.com/language/ref/GeoServer.html) to use map tiles from an external service. There are many compatible...
One of the great things about Mathematica is that it makes it so easy to do so much in so little code. It is partly because of this that I am so frustrated with the amount of time I need to spend developing the *interface* of package functions...
