How do I list the symbols in a .so file
How do I list the symbols being exported from a .so file? If possible, I'd also like to know their source (e.g. if they are pulled in from a static library).

How to get a variable value if variable name is stored as string?
...ue"
a="var1"
echo "${!a}" # outputs 'this is the real value'
This is an example of indirect parameter expansion:
The basic form of parameter expansion is ${parameter}. The value of
parameter is substituted.
If the first character of parameter is an exclamation point (!), it

ValueError: numpy.dtype has the wrong size, try recompiling

(to expand a bit on my comment)
Numpy developers follow in general a policy of keeping a backward compatible binary interface (ABI). However, the ABI is not forward compatible.
What that means:
A package, that uses numpy in a c...
Why is list initialization (using curly braces) better than the alternatives?
...er cannot be converted to another integer that cannot hold its value. For example, char
to int is allowed, but not int to char.
A floating-point value cannot be converted to another floating-point type that cannot hold its
value. For example, float to double is allowed, but not double to float.

From ND to 1D arrays
...the 1D elements are contiguous in memory, but would return a copy if, for example, a were made from slicing another array using a non-unit step size (e.g. a = x[::2]).
If you want a copy rather than a view, use
In [15]: c = a.flatten()
If you just want an iterator, use np.ndarray.flat:

How can I add to List
...
Sorry, but you can't.
The wildcard declaration of List<? extends Number> foo3 means that the variable foo3 can hold any value from a family of types (rather than any value of a specific type). It means that any of these are legal assignments:
List<? extends Number> foo3 = ...
How do I check for nulls in an '==' operator overload without infinite recursion?
...
And what does foo1.Equals(foo2) means if, for example, I want foo1 == foo2 only if foo1.x == foo2.x && foo1.y == foo2.y? Isn't this answering ignoring the case where foo1 != null but foo2 == null?

Is there an equivalent for the Zip function in Clojure Core or Contrib?
...c type; in particular, the number of input lists they accept needs to be fixed. (The zip, zip2, zip3, ... family can be regarded as a specialisation of the zipWith family for the common use case of tupling).
In contrast, Clojure and other Lisps have good support for variable arity functions; map is...
Logical Operators, || or OR?
...ne is ||. They have different precedence and || would work like one would expect normally.
See also: Logical operators (the following example is taken from there):
// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;
