Iterate over a list of files with spaces
...to perform multiple steps the loop version is easier.
EDIT: Here's a nice test script so you can get an idea of the difference between different attempts at solving this problem

How to write a multidimensional array to a text file?
...works fine
import numpy as np
x = np.arange(20).reshape((4,5))
np.savetxt('test.txt', x)
While the same thing would fail (with a rather uninformative error: TypeError: float argument required, not numpy.ndarray) for a 3D array:
import numpy as np
x = np.arange(200).reshape((4,5,10))
np.savetxt('tes...
How to change app name per Gradle build type
...e non-release part, I see that a bit differently as one might want to also test for localization issues while allowing the "release" and "test" builds to coexist on the same device. In such a case both builds might end up with the same launcher label, probably causing some confusion. That is what I ...

How to prevent rm from reporting that a file was not found?
...
-f is the correct flag, but for the test operator, not rm
[ -f "$THEFILE" ] && rm "$THEFILE"
this ensures that the file exists and is a regular file (not a directory, device node etc...)

In PHP, can you instantiate an object and call a method on the same line?
...ose names won't conflict.
So, if you declared a class like this :
class Test {
public function __construct($param) {
$this->_var = $param;
}
public function myMethod() {
return $this->_var * 2;
}
protected $_var;
}
You can then declare a function that r...
Logic to test that 3 of 4 are True
...u want to use this logic in a programming language, my suggestion is
bool test(bool a, bool b, bool c, bool d){
int n1 = a ? 1 : 0;
int n2 = b ? 1 : 0;
int n3 = c ? 1 : 0;
int n4 = d ? 1 : 0;
return n1 + n2 + n3 + n4 == 3;
}
Or if you want, you can put all of these in a singl...

What guidelines for HTML email design are there? [closed]
