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 ...
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:

IPC performance: Named Pipe vs Socket
....
E.g. I implemented a project in C with named pipes, thanks to standart file input-output based communication (fopen, fprintf, fscanf ...) it was so easy and clean (if that is also a consideration).
I even coded them with java (I was serializing and sending objects over them!)
Named pipes has o...
Why can I use a function before it's defined in JavaScript?
...arsed into executable chunks (variable declarations, function definitions, etc.) But at any point can only use what's been defined in the script before that point.
This is different from other programming contexts that process (compile) all your source code, perhaps link it together with any librar...
What exactly is metaprogramming?
...out of Lisp data

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

that you can traverse.

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...
How to debug Google Apps Script (aka where does Logger.log log to?)

Java 32-bit vs 64-bit compatibility
...me hoops the VM has to go through. Notably references are treated in class files as if they took the same space as ints on the stack. double and long take up two reference slots. For instance fields, there's some rearrangement the VM usually goes through anyway. This is all done (relatively) transpa...
