web access - URLSave in Mathematica 10 and 11 on Linux



It seems that URLSave doesn't work as expected with https links in Mathematica 10.4 on Linux. At least in my case (Fedora 30) for


URLSave["https://codeload.github.com/WolframResearch/\
WolframLanguageForJupyter/zip/master", CreateTemporary[]]

I receive


During evaluation of In[1]:= LibraryFunction::libload: The function curlLink_initialize was not loaded from the file /media/Data/Software/Mathematica/10.4/SystemFiles/Links/CURLLink/LibraryResources/Linux-x86-64/libcurllink.so. >>

Out[1]= $Failed


I don't think that WRI is likely to provide support for such an old version, so I'm asking this question in search for some community workarounds.


EDIT: The source of the problem is that for some reason Mma 10 and 11 are not able to load libcurllink.so via


libPath = 
  FileNameJoin[{$InstallationDirectory, "SystemFiles", "Links", 
    "CURLLink", "LibraryResources", "Linux-x86-64", "libcurllink.so"}];
LibraryFunctionLoad[libPath, "curlLink_initialize", {_Integer}, \
"Void"]

Instead, I obtain



LibraryFunction::libload: The function curlLink_initialize was not loaded from the file /media/Data/Software/Mathematica/10.4/SystemFiles/Links/CURLLink/LibraryResources/Linux-x86-64/libcurllink.so. >>

and


LibraryFunction::libload: The function curlLink_initialize was not loaded from the file /media/Data/Software/Mathematica/11.0/SystemFiles/Links/CURLLink/LibraryResources/Linux-x86-64/libcurllink.so.

respectively.


On Mma 11 the workaround would be to use URLDownload which seems to be independent of libcurl and therefore works as expected. On Mma 10 I'm not aware of a such workaround. JLink would be a possibility, but this assumes that one must have Java installed.

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

How to thread a list

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...
