Why is Python such a slow language, on average, compared to C/C++? I learned Python as my first programming language, but I've only just started with C and already I can feel and see the difference.
In Flex ActionScript, a new object can be instantiated via the parameterless constructor with or without (). Example:
var array:ArrayCollection = new ArrayCollection()
or
var array:ArrayCollection = new ArrayCollection
Is there are difference between these two? Is one preferred over the other?

How to make two different files (their contents) equal using terminal in Linux? Suppose i have a file A in which the content is Hello world and i have a file B in which the content is Hello worlds. Now we find the difference between the 2 files using the diff or sdiff utility. Now i want to append the contents of the 2 different files into a single file or make the two different files (their contents) equal using terminal or any other utility.
I am trying to understand the difference between this:
if (isset($_POST['Submit'])) {
//do something
}
and
if ($_POST['Submit']) {
//do something
}
It seems to me that if the $_POST['Submit'] variable is true, then it is set. Why would I need the isset() function in this case?
As I found out that I can use only numerical values in C++'s switch statements, I thought that there then must be some deeper difference between it and a bunch of if-else's.
Therefore I asked myself:
(How) does switch differ from if-elseif-elseif in terms of runtime speed, compile time optimization and general compilation? I'm mainly speaking of MSVC here.
I am trying to detect a postback from Radiobutton list.
I am trying to use following code:
If Page.Request.Params.Get("__EVENTTARGET") = optDownload.UniqueID.ToString Then
But Page.Request.Params.Get("__EVENTTARGET") returns
"ctl00$ContentPlaceHolder1$pnlBarAccounts$i0$i2$i0$CHChecking$Acct1$optDownload$4"
And = optDownload.UniqueID.ToString returns
"ctl00$ContentPlaceHolder1$pnlBarAccounts$i0$i2$i0$CHChecking$Acct1$optDownload"
There is a difference in last 2 characters, how do I detect a postback from Radiobutton list?

If I have the string hello world , how can I modify the regex world|wo|w so that it will match all of "world", "wo" and "w" rather than just the single first match of "world" that it comes to ?
If this is not possible directly, is there a good workaround ? I'm using C# if it makes a difference:
Regex testRegex = new Regex("world|wo|w");
MatchCollection theMatches = testRegex.Matches("hello world");
foreach (Match thisMatch in theMatches)
{
...
}

What is the difference between the createGroup and createGroupIgnoreTooBig?
I understand that createGroup will throw the too big exception when the object exceeds 64k, and createGroupIgnoreTooBig will not. But does it mean that createGroupIgnoreTooBig allows me to create objects larger than 64k, or will it only partially group it?
