I'm using an image as the submit button for a search form, i.e.:
<input id="search" type="image" alt="Search" src="/images/searchButton.png" name=""/>
This has an unfortunate side effect in Chrome and Firefox--the parameters &x=0&y=0 appear on the...

Variable x is int with possible values: -1, 0, 1, 2, 3 . Which expression will be faster (in CPU ticks):
1. (x < 0) 2. (x == -1)
Language: C/C++, but I suppose all other languages will have the same.
P.S. I personally think that answer is (x < 0...

In IE, "x".split(/(x)/).length returns 0
In Firefox, Chrome, Safari, and Opera, it returns 3 .
Does anybody know the reason why? If possible, a reference link will be greatly appreciated.
I believe that it is a IE regex implementation issue, but I can...

IE both ignores empty values and capture blocks within regular expressions .

You're correct that there are implementation issues .

I know- Premature optimization.
But I've got code that's supposed to find out if a position is changed vs a cached position.
Current code is:
if(abs(newpos-oldpos) > 1){ }
Is it more efficient to use the following?
if(abs(newpos-oldpos) != 0){ .......

x > 1 is not the same as x != 0.
I am missing something, they do not do the same thing .

Int main(void){ float x =1; float y =2; while (x<y){ x = x +1 ; y = y +1; } printf("x is %d\n", x); printf("y is %d\n", y); }
I would expect x and y to increase to the point we run out of bits, but it seems like x and y is alway 0 in this case...

Most compilers can warn you about these types of errors if you set is for an integer.

Given a string of length N, how many ways are there of splitting it into X substrings (where X>0)?

Answer Snippets (Read the full thread at stackoverflow):
X > N --> 0 partitions(N,X) --> Σ (I,0,N-X) λ partitions(N-I,X-1)
Now go finish yourAs many as there are combinations of X numbers that sum up to N ;)
Well, there are N-1 places of substrings X is one....

If I have something like:
long x = 1/2;
shouldn't this be rounded up to 1? When I print it on the screen it say 0.

Even if I had long x = (long)(0.9), the result" is never 0.5 before assign to long

Cast will force this to be truncated to 0.

In the following piece of code (taken from the Groovy User Guide ), why prefix the assignment with the keyword def ?

The def keyword can be removed, and this snippet...

And groovy treats it (mostly) like a globally scoped variable:
x = 1 assert x == 1 assert this.binding.getVariable("x") == 1
Using the def keyword instead does not put the variable in the scripts that are created with "def" in the....

How do you return 0 instead of null when running the following command:
SELECT MAX(X) AS MaxX FROM tbl WHERE XID = 1
(Assuming there is no row where XID=1)

Like this (for MySQL):
SELECT IFNULL(MAX(X), 0) AS MaxX FROM tbl WHERE XID = 1
For MSSQL replace IFNULL with ISNULL or for Oracle use NVL
In SQL 2005 / 2008:
SELECT ISNULL(MAX(X), 0) AS MaxXFROM(MAX(X), 0, MAX....

That is not limited to {0, 1, 2}.
