When I do System.out.println(map) in Java, I get a nice output in stdout. How can I obtain this same string representation of a Map in a variable without meddling with standard output? Something like String mapAsString = Collections.toString(map)?
I've got a situation where an ini file is in memory (in a string variable) and I'd like to read values out of it without writing the ini file data to disk.

Ok so, Im using jQuery to do username and email checks before a signup...
this sets a variable true or false depending on the response from php.
$(document).ready(function() {
if (usr_checked == true) {
if (em_checked == true) {
$("#registerbttn").removeAttr("disabled");
}
}
else {
$("#registerbttn").attr("disabled", "disabled");
}
});

What's the easiest way to change a text's color based on a variable?

When I reading the code of CodeIgniter,I found some functions written as follows:
function &get_instance()
{
global $CI, $OBJ;
if (is_object($CI))
{
return $CI;
}
return $OBJ->load;
}
I can understand variable refrence,but I can hardly get this through.Is it necessary to use this function style?And any benefit?
Thanks.
I am building an iphone app and would like to keep track of how many times it has been opened so that I can prompt the user to do certain actions after it has been opened X number of times. I have thought about storing a variable in Core Data which I update every time it is opened, but this seems like a waste since it is a singleton data, not multiple instances of an object. What is the best way to store data like this and access it without slowing down the app opening time?
Hi,
I am trying to only select the objects where the id is smaller than an int value.
e.g.: i have 3 objects - id = 1, id = 2, id = 3
Now I want to only get the objects with the id smaller than the variable i = 2;
How can I manage this?
sql = "SELECT id FROM table_name WHERE id <= i";
Thanks ;-)
In NumPy functions, there are often initial lines that do checking of variable types, forcing them to be certain types, etc. Can someone explain the point of these lines? What does subtracting a value from itself do?
t,w = asarray(t), asarray(duty)
w = asarray(w + (t-t))
t = asarray(t + (w-w))
