I am not very familiar with the Javascript syntax bellow. Can anyone shade light about the sense of this block? For what purpose?
(function foo() {
alert('bar');
})();
Thanks in advance.
function get_ibo_id() {
if($registerquery = $this->conn->query("SELECT ibo_id FROM fasttrack WHERE count <
8 && flag = 1 ")){
$this->increase_count();
while ($row = $registerquery->fetch_assoc()) {
return $row[ibo_id];
}
}
else return "No id";
}
it always enters the if block even if the condition is not satisfied... going crazy
abstract class db_table {
static function get_all_rows() {
...
while(...) {
$rows[] = new self();
...
}
return $rows;
}
}
class user extends db_table {
}
$rows = user::get_all_rows();
I want to create instances of a class from a static method defined in the abstract parent class but PHP tells me "Fatal error: Cannot instantiate abstract class ..." How should I implement it correctly?
Is there a hash function that returns a 16-digit hex value (as MD5 returns 32-digit), or is there a library (for C++) in which I can use MD5 or SHA-1 which returns a 16-digit value
Hello,
I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly.
The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power.
Clashes are not a problem.
I'm using javascript, so it shouldn't be too complicated to implement.
hi.
I have a multiple file upload form(html5) and want to update my view as soon one of the images is transfered to my image server.
Currently I upload the files with ajax and use response_to_parent to update my upload view when all images are transfered to the image server.
Is it possible to call a Javascript function from the controller more than once per action?
def upload
params[:images].each do |file|
upload_to_image_server(file)
#page << Update upload View
end
end
Thanks,
Michael

I'm using the JQuery autocomplete plugin. I wish to override the implementation of the filllist() function. Can someone point me to an example of how to do this?
I have problem querying table with variable in IN function.
SELECT
s.date,
(SELECT
GROUP_CONCAT(value)
FROM value
WHERE id_value
IN(s.ref_values)
)
AS vals
FROM stats s
ORDER BY s.date DESC
LIMIT 1
Where s.ref_values is '12,22,54,15'. I get only one return for first number (12).
When I insert that value directly in IN(12,22,54,15) it finds all 4.
So, there must be problem with using variable in IN. What am I doing wrong?
Hi Stackoverflow,
I have been looking at the source code of raphael (http://raphaeljs.com/index.html) and I see a lot of stuff like !variable && function() (e.g.: !svg.bottom && (svg.bottom = this); )
What does that exactly do? Does it check first and execute only if not true?
Thanks.
I'm new to PHP and I'm confused seeing some examples calling a function with a @ prefix like @mysql_ping().
What is it for? Googling / searching is not much of a help since @ gets discarded and 'alias' is not good enough keyword.
Code Sinnpet:
int CreateaTCPSocket()
{
int iSockID = ACE_OS::socket(......);
ACE_OS::set_flags(iSockID,O_NONBLOCK);
ACE_OS::bind();
if (ACE_OS::connect(iSockID ,....) < 0)
{
if (ACE_OS::select(.....,timeout) <= 0)
{
return INVALID_HANDLE;
}
}
return iSockID;
}
My question is when connect is failed for non-block error and select is called and say select return success then again we need to call connect or select function internal do connect?
Pandas has the following indexers:
Object Type Indexers
Series s.loc[indexer]
DataFrame df.loc[row_indexer,column_indexer]
Panel p.loc[item_indexer,major_indexer,minor_indexer]
I would like to be able to index dynamically by axis, for example:
df = pd.DataFrame(data=0, index=['row1', 'row2', 'row3'], columns=['col1', 'col2', col3'])
df.index(['row1', 'row3'], axis=0) # index by rows
df.index(['col1', 'col2'], axis=1) # index by columns
Is there a built-in function that does this?

I'm trying to write a function :
Input:
Source range, Source value, output range, curve type (Linear, smooth)
Output:
The output is the "source value" converted into the "output range"
according to the curve type.
I hope I am making sense here...
Any ideas ?
Thanks.
I have following code:
static __inline__ LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
After compilation I got following warning:
inlining is unlikely but function size may grow
I removed the inline and changed into the following :
static LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
Now I get the following warning:
list_List is defined but not used.
Can anybody please suggest me how can remove that warning.

Is there a difference, performance or efficiency wise, between placing javascript calls such as blur, onclick etc. in $(document).ready(function(){ as opposed to placing them in DOM?
Thanks!

Can I pass arrays to functions just as I would do with primitives such as int and bool?
Can I pass them by value?
How does the function know of the size of the array it is passed?
