I have run across a condition statement which I have some difficulties to understand. It looks like (please note the +-sign on the right-hand-side) this:
obj.length === +obj.length.
Can this condition and its purpose/syntax be explained?
Looking at the statement (without knowing it) provokes the impression that it is a dirty hack of some sort,…
Im looking for a template for a terms of usage text based on social media websites. Im actually a coder and not into the legal blabla in general. Ofcourse you could spend a thousand or 2 on a lawyer but just a 3/4 paper text shoulder;t be to hard to compile yourself with some help.

So, it'm about to buy a fresh videocard. Since I do most of my stuff on Linux, I wonder how well will either videocard perform. I recently had a good experience with GeForce 6600 with proprietary drivers and a less than satisfactory experience with Radeon 9000 a while ago. From my experience, proprietary drivers for GeForce used to work very…
This base class for some shapes I have in my game looks like this. Some of the shapes can be resized, some of them can not.

shape.Width = x;
shape.Height = y;
}

How do I spawn a sprite anytime later in the game when the game starts?
I'm using FlashDevelop with Flixel. I did try it in override public function create(): void. It works only in the beginning. I try it using if (FlxG.score == 1) but it doesn't work. I also tried it in override public function update(): void. It works and it is…
Which is more expensive in terms of processing costs
if ( x < 20 && z == "M") {
// statements 3
}
if ( x >= 20 && w && x <= 65) {
// statements 1
}
if( x >= 20 &&z != "M"){
// statements 2
}
or this
if ( x < 20 ) {
if( z == 'M') // statements 3;
} else

I've have a workflow whose root activity is a custom NativeActivity with a public InArgument called XmlData. When I try and use this argument in a child If activity I get the following error using XmlData within the condition:
'XmlData' is not declared. It may be inaccessible due to its protection level

What I would like to do is use the Context module to insert $body_classes of my choosing based on a Taxonomy Term condition. Fine, that's what the Context module is for. Seems simple enough IF your content/page source is a node that is involved with the appropriate Terms. However, I have a page generated by Views that has the…
It seems like the safest way to think of an Inner Join is to think of it as a Cross Join and then satisfying some condition(s)?
Because the equi-join can be obvious, but the non-equi-join can be a bit confusing.
But if we always use the Cross Join, and then filter out the ones satisfying the condition, then we get the…
I was wondering what was the most clean and understandable syntax for doing condition checks on nullable bools.
Is the following good or bad coding style? Is there a way to express the condition better/more cleanly?
bool? nullableBool = true;
if (nullableBool ?? false) { ... }
else { ... }
especially the if…
I have TestGen4Web script for automating testing on a web-based user interface that has a popup window (hey i didn't write that ui..).

I'm writing a data access layer. It will have C# 2 and C# 3 clients, so I'm compiling against the 2.0 framework. Although encouraging the use of stored procedures, I'm still trying to provide a fairly complete ability to perform ad-hoc queries. I have this working fairly well, already.
For the convenience…
Hi,
We are using an extractor application that will export data from the database to csv files. Based on some condition variable it extracts data from different tables, and for some conditions we have to use UNION ALL as the data has to be extracted from more than one table. So to satisfy the UNION ALL…
In this post we will see how a Role can be data secured by multiple Business Units (BUs). Separate Data Roles are generally created for each BU if a corresponding data template generates roles on the basis of the BU dimension. The advantage of creating a policy with a rule that includes…

In a book I am reading there is a piece of code :
string x;
size_t h=0;
for(const char* s=x.ctr();*s;++s)
h=(h*17)^*s;
Regarding this code, I have two questions:
how can *s be a condition? what does it mean?
what does "h=(h*17)^*s" mean?
Thanks…
while( fscanf( tracefile, "%s ", opcode ) != EOF ){blah}
Occasionally I need to cause fscanf to re-read a line upon a certain condition in my code being met. Is this possible; how would I do that?
Thanks.
