To summarize and move from an unanswered stack: I have received a short and simple response from Wolfram tech support, informing me that they have "filed a bug report with the development team" and stating that "hopefully it would be improved in future release." So yes, I guess that makes it a bug. – ibeatty Aug 12 at 20:06 And indeed it is ...

I have the same difficulties with 10.0 on Windows. The best I can get to display the complete area of Russia is GeoGraphics[Polygon @ Entity["Country", "Russia"], GeoProjection -> "Mercator", GeoRange -> {{40, 80}, {25, 195}}, ImageSize -> 600] Update To also show Kaliningrad in the far west GeoGraphics[{ PointSize[0.02], ...

It is version 10.0 specific bug. Please upgrade to a more recent version Version 10.0.0: Version 10.1 and above: Tested on Linux. It seems that other OS have the same behavior. One can extract proper options from recent version and put them to 10.0.0: GeoGraphics[Polygon@Entity["Country", "Russia"], GeoProjection -> {"LambertAzimuthal", ...

This is not an answer; it is a comment that needs to show an image. I don't get what you show from GeoGraphics[Polygon @ Entity["Country", "Russia"]] I get I evaluated your code with V10.3 running on OS X 10.10.2.

This bug is fixed in v10.0.2.0.

Problem was fixed in version 10.

It looks like a problem of numeric cache: SetSystemOptions["CacheOptions" -> {"Numeric" -> {"Cache" -> False}}]; tmp = {3/Sqrt[2] + 3 Sqrt[2], 3/Sqrt[2] + 3 Sqrt[2]}; grouptmp1 = GroupBy[tmp, N[#, 8] &]; grouptmp2 = GroupBy[tmp, N[#, 8] &]; grouptmp1 === grouptmp2 (* True *) With caching I get False. See also Simon Woods's comment. ...

Quit the kernel before each test. This is on MMA 10.3 on Mac OS X. Simplify the problem We can simplify so that tmp is much much smaller and easier to analyse: rot1 = RotationTransform[{{1, 0, 1}, {0, 0, -1}}, {0, 0, 0}]; tmp = rot1@Tuples[Range[3, 6], 3]; grouptmp1 = GroupBy[tmp, N[Last[#], 8] &]; grouptmp2 = GroupBy[tmp, N[Last[#], 8] &]; ...

Although this question has been answered by a bug statement, I found it interesting to study some aspects in more detail. The study could not explain the internal cause of the bug. But, besides taking into account that the OP provides two different integrals the study shows that applying a simple unified regularization procedure leads to correct results. ...

As mentioned in the question, this is a bug. For a possible workaround, try RegionPlot[lhmin[y, M] > 0, {y, 0.1, 1.}, {M, 0, 10}, "NumericalFunction" -> False] Some related questions: (1), (2), (3).

This is a limitation in TemporalData that MovingMap was designed to work with. Note that TimeSeries and EventSeries are really just special cases. I don't know if it is a necessary limitation but a decision was made at the time they were created that the dimensionality of the data values need to be consistent. Now whether this restriction should be relaxed ...

As far as I'm concerned, this is a clear bug. Let's do a small amount of spelunking: p1 = ContourPlot[f[x, y] , {x, -2, 2}, {y, -2, 2} , Contours -> {1, N@Sqrt[2], 3}, ContourShading -> None]; p2 = ContourPlot[f[x, y] , {x, -2, 2}, {y, -2, 2} , Contours -> {1, Sqrt[2], 3}, ContourShading -> None]; GraphicsRow@{p1,p2} Hovering on the ...

There are several Graph-related bugs that show up only for certain graphs, most likely due to how these graphs are stores internally. There are several possible internal graph representations used by Mathematica. When you find that something like this happens, try recreating the graph in one of several possible ways: g = Uncompress@Compress[g] will ...

Perhaps it's a nuisance (bug?) of RandomGraph[ ]. Here is a way to force it: g = Graph[VertexList@#, EdgeList@#] &@RandomGraph[{1, 0}]; g1 = VertexAdd[g, 2]; g2 = EdgeAdd[g1, UndirectedEdge[1, 2]]

jSoupLink can be used as a workaround, like this: << jSoupLink html2text[html_] := First@jSoupLinkParseHTMLFragment[ "<div id=\"container\">" <> html <> "</div>", "#container", "text" ] html2text["a<span>b</span>c"] (* Out: abc *) html2text["a<foo>b</foo>c"] (* Out: abc *)

One can import raw text and use this example to remove HTML tags StringReplace[ #, "<" ~~ Except[">"] .. ~~ ">" -> ""] &@ ImportString["a<bar>b</bar>c", {"HTML", "Source"}] (* "abc" *)

With $Version (* 10.3.0 for Microsoft Windows (64-bit) (October 9, 2015) *) Mathemeatica returns a limit that depends on r, as it should. Plot[Limit[E^-(r^2)^(2*n)*r*2*Pi, n -> Infinity], {r, -2, 2}, AxesLabel -> {r, Lim}] Addendum Although Limit returns unevaluated for arbitrary r, it can be made to produce useful results by making ... 5 I don't know what causes the issue (which looks like a bug to me), but I generally find the best way to deal with exerting control over Import not doing quit the right thing with HTML is to use the "XMLObject" element and use ordinary Mathematica functions on it, like so: In[1]:= ImportString@ ExportString[ ... 4 Extended comment Here is a minimal example which shows clearly that the problem is the difference of the axis scales even for equally spaced points. It concerns ListDensityPlot and ListContourPlot but also ListPlot3D(see Edit below) fp[x_, y_] := (x^2 + y^2) This is the function plot: ContourPlot[fp[x, y], {x, -1, 1}, {y, -1, 1}] Now, we take ... 14 It definitely has something to do with the Interpolation function. Evaluating tempdata = Import["http://www.inrim.it/~magni/cm.dat.gz", "Table"]; cmfunc = Interpolation[tempdata] we get the warning Interpolation::udeg: Interpolation on unstructured grids is currently only supported for InterpolationOrder->1 or InterpolationOrder->All. Order will ... 2 Seems like this was a bug. It's fixed in Version 10.3. 1 It is probably a bug introduced in v10. As of v9, these are the results: R[t_] = Through[#[t]] & /@ Table[Subscript[r, i, j], {i, 2}, {j, 2}]; ParametricNDSolveValue[{R'[t] == I R[t], R[0] == DiagonalMatrix[{0, n}]}, Subscript[r, 2, 2], {t, 0, 10}, {n}][1][1] ParametricNDSolveValue[{R'[t] == I R[t], R[0] == DiagonalMatrix[{0, 1}]}, Subscript[r, ... 6 It seems to me that ListDensityPlot connects points incorrectly because of the very big ratio of x- and y-scale. So I propose to rescale the data data = Import["http://pastebin.com/raw.php?i=2p4ew0NJ", "Table"]; ListDensityPlot[Transpose[Transpose@data/{1000, 1, 1}], PlotLegends -> Automatic, PlotRange -> {{0, 13}, {0, 8}, {0, 0.0007}}] Then you ... 10 In versions from 8 to 10.3 the option Mesh->Full gets rid of the unwanted markers: ListLinePlot[{{12., 13., 6., 16., 15., 12., 7., 15., 15., 17.}, {9., 9., 9., 9., 9., 9., 9., 9., 9., 9.}}, Filling -> {1 -> {2}}, Frame -> True, FrameTicks -> {{Automatic, None}, {Automatic, None}}, GridLines -> {Range@10, Automatic}, PlotMarkers ... 3 I have a Dell 17R SE with nVIDIA GeForce GT650M with 3D capabilities and Mathematica 10.3 on Windows 10 64bit. Today I got an answer on my email to support@wolfram.com saying there was no issue on the machine of the support engineer. So I again let Mathematica install the CUDA paclet. The download was extremely slow. But in the end version 10.2.0.3 was ... 4 This does not solve the problem, but provides some additional observations. As DiscretizeRegion[Interval[{0, 1}], MeshRefinementFunction -> (Echo@#2 > 0.01 &)] or DiscretizeRegion[Interval[{0, 1}], MeshRefinementFunction -> ((Print[#2]; #2 > 0.01) &)] work without any error messages I conclude that Reap is used somewhere within ... 7 I saw this problem recently on the Wolfram Community website and answered it there. I'll copy my answer here (http://community.wolfram.com/groups/-/m/t/603973) I'm not sure if there's a simple way to prevent the issue. I would do this by basically reconstructing the ListVectorPlot Function from VectorPlot. To make it easy, I'll just make an Interpolation of ... 3 Wolfram Cloud has released 1.25. The issue mentioned here has been fixed for Windows/Chrome. Welcome to try again. 4 Yes, the crash is a bug and has been fixed as of version 10.2. But I would recommend upgrading to 10.3 to avoid running into this Nearest problem. Possible workarounds for 10.0.2 or 10.1 include applying N as shown in the question, or specifying DistanceFunction -> (Norm[#1 - #2] &). 1 This bug was present in Mathematica version 8.0:$Version Assuming[ -nn <= m <= nn && m \[Element] Integers, Simplify[Sum[KroneckerDelta[m, n] f[n], {n, -nn, nn}]] ] Since version 9.0 this Sum remains unevaluated:

As confirmed by @Stefan R, it is a bug in 10.3. In the meanwhile, a possible workaround is : Merge[xx, Mean]
