I am learning Javascript; and most books only give you partial
definitions for the functions they show you. Here is a line of code
from a browser sniffing function:
var isWin = (navigator.platform.indexOf("Win") !=-1) ? true:false;
What does the -1 stand for.
Excuse me for such a basic question, but I can't find the answer
anyway.

Open Source DRM? What does everyone think about it? Will Open Source

Will DRM ever be integrated into common LAMP applications?

Given
int x;
What does
x evaluate to?
If x is 0, it equals 0x31, the ascii value of '1'. So for some
reason, x evaluates to *(y+x) where x is a non pointer/array type.

I'm trying to convert this macro to a c# function but I have a big problem.
It's on the LEFT side of an assignment statement and I am extremely
flustered over this one because I'm a little rusty and have been struggling
over this for days, not wanting to show all my ignorance in final desparate
plea for help which this is ...
Here is the macro ...

Hi,
what does the Me.DesignMode-Property turn back. I tried to set a
MsgBox(Me.DesignMode) in my form's and control's Sub New(), but it allways
turns back 'false', even if the form or control is open in Designmode.
To set correctly the properties when changed in the property-browser while
designing I need to know if the control is in designtime or in runtime-mode.
Is there a way to manage this?

I'm running two different compilers against some hairy macros and one,
gcc, doesn't like my token pasting result so much. It says, " "." and
"foo" does not give a valid preprocessing token ". Some further reading
suggests that since .foo is not a valid preproc. token that I can't
really do what I want, portably. The macro looks like this:

Hi,
I have used bitfields in C before and I understand all the AND/OR operations
etc. While learning C# I was told to mark all by "bitfield enums" with the
attribute. Do why? Exactly what does this attribute do?
The MSDN docs says: " Indicates that an enumeration can be treated as a bit
field; that is, a set of flags." but that really doesn't tell you anything

Hi,
When reading the source code of dojo, it uses the following statement
quite often. What does it mean? What I do not understand is it has a
function definition enclosed in a pair of parenthesis and the the last
pair of parentheses.
( function() {

hi,
what does this exactly mean:
"Except for the new, delete, typeid, dynamic_cast, and throw operators
and the try-block, individual C++ expressions and statements need no
run-time support." TC++PL § 1.3.1

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
