I understand BFS, and DFS, but for the life of me cannot figure out the difference between iterative deepening and BFS. Apparently Iterative deepening has the same memory usage as DFS, but I am unable to see how this is possible, as it just keeps expanding like BFS.
If anyone can clarify that would be awesome.

Hi I would like to know diff between the above comparisons?
I am getting null pointer exception when I check object.getItems() == null.
But if I change it to null == object.getItems(), it workes fine.
I did look into this http://stackoverflow.com/questions/2938476/what-is-the-difference-between-null-object-and-objectnull-closed
But I didnt get satisfactory answer.
The only difference is that Winmain takes char* for lpCmdLine parameter, while wWinMain takes wchar_t*.
On Windows XP, if an application entry is WinMain, does Windows convert the command line from Unicode to Ansi and pass to the application?
If the command line parameter must be in Unicode (for example, Unicode file name, conversion will cause some characters missing), does that mean that I must use wWinMain as the entry function?
Is there any difference — performance or otherwise — between generator expressions and generator functions?
In [1]: def f():
...: yield from range(4)
...:
In [2]: def g():
...: return (i for i in range(4))
...:
In [3]: f()
Out[3]: <generator object f at 0x109902550>
In [4]: list(f())
Out[4]: [0, 1, 2, 3]
In [5]: list(g())
Out[5]: [0, 1, 2, 3]
In [6]: g()
Out[6]: <generator object <genexpr> at 0x1099056e0>
I want to know the difference between ObservableCollection and BindingList because I've used both to notify for any add/delete change in Source, but I actually do not know when to prefer one over the other.
Why would I choose one of the following over the other?
ObservableCollection<Employee> lstEmp = new ObservableCollection<Employee>();
or
BindingList<Employee> lstEmp = new BindingList<Employee>();
I have created the following code to update the text contents of all spans like this every minute. There are numerous of these spans on the page which all need to be updated every minute:
<span unix="1372263005" class="time_ago">4 minutes ago</span>
The code is as follows:
window.setInterval(function(){
var unix = $(".time_ago").text();
var now = new Date().getTime();
var amount = 0;
var difference = 0;
difference = now - parseInt(unix);
if (difference < 60)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">a few seconds ago</span>');
}
else if (difference < 120)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">a minute ago</span>');
}
else if (difference < 3600)
{
amount = floor(difference / 60);
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' minutes ago</span>');
}
else if (difference < 7200)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">an hour ago</span>');
}
else if (difference < 86400)
{
amount = floor(difference / 3600);
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' hours ago</span>');
}
else if (difference < 172800)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">a day ago</span>');
}
else if (difference < 2635200)
{
amount = floor(difference / 86400);
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' days ago</span>');
}
else if (difference < 5270400)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">a month ago</span>');
}
else if (difference < 31622400)
{
amount = floor(difference / 2635200);
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' months ago</span>');
}
else if (difference < 63244800)
{
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">a year ago</span>');
}
else (difference >= 63244800)
{
amount = floor(difference / 31622400);
$(".time_ago").text('<span unix="' + unix + '" class="time_ago">' + amount + ' years ago</span>');
}
return false;
}, 60);
EDIT) Ok, now I have made some changes on your advice but it's changing the span texts to 43351 years. Any ideas why it is doing that?
Can anybody explain (or suggest a site or paper) the exact difference between triggers, assertions and checks, and also describe where I should use them?
EDIT: I mean in database, not in any other system or language.
to add a list form that contains all languages one can use the widget sfWidgetFormI18nChoiceLanguage that is included in symfony or install a plugin called sfFormExtraPlugin and use its form sfFormLanguage.
this is mentioned in http://www.symfony-project.org/jobeet/1_4/Doctrine/en/19
i wonder what the difference is? why should i use the plugin when the standard widget could display a list of all languages?
thanks
I'm trying to understand the difference between sequences and lists.
In F# there is a clear distinction between the two. However in C# I have seen programmers refer to IEnumerable collections as a sequence. Is what makes IEnumerable a sequence the fact that it returns an object to iterate through the collection?
Perhaps the real distinction is purely found in functional languages?
We have been using temporary table to store intermediate results in pl/sql Stored procedure. Could anyone tell if there is a performance difference between doing bulk collect insert through pl/sql and a plain SQL insert.
Insert into
or
Cursor for
open cursor
fetch cursor bulk collect into collection
Use FORALL to perform insert
Which of the above 2 options is better to insert huge amount of temporary data?

both are giving number of elements of array. So what is difference between the two?

I have read somewhere that Silverlight is subset of WPF , then why triggers are not used in the silverlight and the States are used. what is difference between these two, Why not the triggers are used in silverlight 3.0
the following syntax throws an compile time error like
Cannot convert type 'string' to 'int'
string name=(Session["name1"].ToString());
int i = (int)name;
whereas the code below compiles and executes successfully
string name=(Session["name1"].ToString());
int i = Convert.ToInt32(name);
I would like to know
1) why the compile time error occurs in first code
2) what's the difference between the 2 code snippets
I have two servers, one running core i7 920 (8 logic CPUs at 2.8Ghz), the other running Xeon X3430 (4 logic CPUs at 2.4Ghz). For the same .NET 4 application, CPU usage on the first machine is 6%; on the second machine it is 50%! I wonder what makes this huge difference. And how can I diagnose the cause of the issue?
Hi,
what is the difference between following function declarations, which create and return the array in C/C++? Both methods create the array and fill it with proper values and returns true if everything passed.
bool getArray(int* array);
bool getArray(int* array[]);
Thanks

I would like to know the difference between a programmer and a software developer. From what I understand a programmer is someone who codes a solution whereas a software developer finds a solution to a particular problem and then designs the application. Is this correct?
