RESTful Authentication
...r, which will persist (there is no LogOut-like feature here), some server-side additional CPU consumption, and the fact that the user-name and password are transmitted (over HTTPS) into the Server (it should be more secure to let the password stay only on the client side, during keyboard entry, and ...
Scala: Abstract types vs generics
...uld argue that this distinction is fairly arbitrary.
The Scala Way
We decided to have the same construction principles for all three sorts of members.
So you can have abstract fields as well as value parameters.
You can pass methods (or "functions") as parameters, or you can abstract over them.
Yo...
Why does struct alignment depend on whether a field type is primitive or user-defined?
...
I think this is a bug. You are seeing the side-effect of automatic layout, it likes to align non-trivial fields to an address that's a multiple of 8 bytes in 64-bit mode. It occurs even when you explicitly apply the [StructLayout(LayoutKind.Sequential)] attribute. T...
Why is a round-trip conversion via a string not safe for a double?
...ber is pretty simple -- it just calls _ecvt, which is in the C runtime:
void DoubleToNumber(double value, int precision, NUMBER* number)
{
WRAPPER_CONTRACT
_ASSERTE(number != NULL);
number->precision = precision;
if (((FPDOUBLE*)&value)->exp == 0x7FF) {
number->...

Logical operators for boolean indexing in Pandas
...are designed to work with scalars. So Pandas had to do one better and override the bitwise operators to achieve vectorized (element-wise) version of this functionality.
So the following in python (exp1 and exp2 are expressions which evaluate to a boolean result)...

What's the difference between eval, exec, and compile?
...nd exec is used to execute dynamically generated Python code only for its side effects.
eval and exec have these two differences:
eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.
