comment Why does my code produce NDSolveValue::ndnum?
With Mathematica 8.0.0.0, I don't get NDSolveValue::ndnum, but the same output as in the question (except for the prime on the end; is that a copy/paste error?).

Did you try them separately?

Does it work if you prefix the space in "Program Files" with a single backslash? Or maybe use "CompilerInstallation" -> "\"C:...bin\""?

comment Plotting on the Raspberry Pi
Yes, I noticed that. Given that it came with the RPi for free, it didn't strike me as odd. Especially since you normally can do everything also with the kernel interface, just less comfortably.

Ah, thank you, I didn't notice that. After I've seen the "Wolfram" Icon, I didn't think of searching for another icon ;-) I now found the notebook interface, and there plotting indeed works fine.

comment How to Use Mathematica as a C/C++ compiler
Of course Mathematica can be used as C compiler. You just first have to write the Mathematica code that compiles C programs. ;-)

Err ... your expression is shown here as basically garbage. Could you please rewrite it in LaTeX notation?

comment How to trigger UNIX command-line command from Mathematica notebook?
@DavidZ: Thank you for that information. I just checked with Run["false"] and I indeed got 256 instead of 1, providing further evidence for this hypothesis.

comment MathKernel: No such file or folder of this type
If it outputs 0, you obviously have permissions. Unfortunately it also means I'm out of ideas for now.

OK, so the file is not executable. This is likely the problem. Do you generally have execute permissions on your home directory?

The + after the last x indicates that there is access control beyond the standard Unix rights. What does test -x /home/*****/Mathematica/10.0/SystemFiles/Kernel/Binaries/Linux-x86-64/MathKernel; echo $? output?

Do you also get that warning if you type df in the shell? Also, what is the output of ls -l /home/*****/Mathematica/10.0/SystemFiles/Kernel/Binaries/Linux-x86-64/MathKernel?
