| The current failure is somewhat expected since the cloud has security restrictions on setting environment variables and the notion of a home directory is slightly different between the kernel process and the cloud user account. However, placing... |
| It is a consequence of ``` In[10]:= Norm[{a, b}] Out[10]= Sqrt[Abs[a]^2 + Abs[b]^2] ``` where `a` is `Sin[t] + t*Cos[t]` and `b` is `2 t`. You may get a result closer to the expected one by specifying assumptions, for example ... |
| The difference in upper case of GUROBI vs Gurobi matters (although perhaps both of them should be accepted) In[1]:= QuadraticOptimization[2 x^2 + 20 y^2 + 6 x y + 5 x, { -x + y >= 2, y >= 1}, {x, y}, Method -> "GUROBI"] ... |
| By the way, a useful command to keep in mind is https://reference.wolfram.com/language/ref/PacletDataRebuild.html |
| There should be no significant difference between these machines which use the same CPU. There is some normal variability between runs of the benchmark code, but once warmed up, expect most of the results to be around 3.00, plus or minus a percent or... |
| > So I must use the Microsoft compiler No, that is not necessary. Mingw has an appropriate definition for the `__int64` type in the `_mingw.h` header file, which is included from a number of other standard headers. For example you could do ... |

| Yes, based on the hardware and the operating system, it should work. But I believe no specific testing has been done with this device. |
| This problem has been fixed by a paclet update, which can be installed by evaluating PacletSiteUpdate /@ PacletSites[]; PacletInstall["CURLLink"] and restarting Mathematica. More details about the underlying cause of the bug can be... |
| Mathematica 12.1 was ready and being downloaded when the blog post appeared. There are other products in the pipeline like WolframEngine or the localized versions that usually take a few additional days to go through final testing. |
