how does multiplication differ for NumPy Matrix vs Array classes?
...7, 214, 393]])
but this operations fails if these two NumPy matrices are converted to arrays:
>>> a1 = NP.array(a1)
>>> a2t = NP.array(a2t)
>>> a1 * a2t
Traceback (most recent call last):

Why don't Java Generics support primitive types?
...a = (ClassA)list.get(0);
So, anything that is used as generics has to be convertable to Object (in this example get(0) returns an Object), and the primitive types aren't. So they can't be used in generics.

Differences between “BEGIN RSA PRIVATE KEY” and “BEGIN PRIVATE KEY”
...gorithms can be used.. But some software (mysql) can use only PKCS#1 keys. Converting from PKCS#8 to PKCS#1 can be done with openssl rsa -in key.pem -out key.pem. Converting the other way can be done with openssl pkey -in key.pem -out key.pem.

Why does this code segfault on 64-bit architecture but work fine on 32-bit?
... cast the malloc return in C. The void* that it returns will be implicitly converted to a pointer of the correct type (unless you haven't included the header in which case it probably would have warned you of the potentially unsafe int-to-pointer conversion).

Return array in a function
...eturn a pointer. Furthermore, an array type in the argument list is simply converted to a pointer.
int *fillarr( int arr[] ) { // arr "decays" to type int *
return arr;
}
You can improve it by using an array references for the argument and return, which prevents the decay:

Incidentally, you can also do float('Inf'), Decimal('Inf'), or math.inf (3.5+) to assign infinite numbers. (And also see math.isinf(...))...
