Simulating tremor (from e.g. Parkinson's Disease) with the mouse on a webpage?
...) — to compile program above, just use:
user@host:/path$ gcc -std=gnu99 file.c -o m
where file.c is the name of your C source code file, then you'll get executable, called m in your directory. Most likely you'll need permissions to write into mouse device directly, so you may use sudo:

NumPy or Pandas: Keeping array type as integer while having a NaN value
...2
2 3
3 NaN
dtype: object
For cosmetic reasons, e.g. output to a file, this may be preferable.
Pandas v0.23 and earlier: background
NaN is considered a float. The docs currently (as of v0.23) specify the reason why integer series are upcasted to float:
In the absence of high performa...
Passing a std::array of unknown size to a function
...ultiplier );
}
(not tested, but design should work).
Then, in your .cpp file:
void mulArrayImpl(contig_range<int> rng, const int multiplier) {
for(auto& e : rng) {
e *= multiplier;
}
}
This has the downside that the code that loops over the contents of the array doesn't know ...

...int the user to resource B, meaning the user will run a second request to fetch B. A slightly different way of handling this would be to do an internal redirect, which means that while processing A, Flask will make a new request to itself for resource B, and use the results of this second request as...
What does default(object); do in C#?
...he requested type.
For all reference types (defined with class, delegate, etc), this is null. For value types (defined with struct, enum, etc) it's an all-zeroes value (for example, int 0, DateTime 0001-01-01 00:00:00, etc).
It's mostly used with generic code that can be applied to both reference ...
What exactly is metaprogramming?
...out of Lisp data
objects. And not in the trivial sense
that the source files contain
characters, and strings are one of the
data types supported by the language.
Lisp code, after it's read by the
parser, is made of data structures
that you can traverse.
If you understand how compi...
Beyond Stack Sampling: C++ Profilers
...py, and as we speak, VTune is installing. I've tried to use the VS2008 profiler, and it's been positively punishing as well as often insensible. I've used the random pause technique. I've examined call-trees. I've fired off function traces. But the sad painful fact of the matter is that the app...
