I wish to get an extension of an image I am uploading but I just get an array back. Is there a way to just get the extension itself
$userfile_name = $_FILES['image']['name'];
$userfile_extn = explode(".", strtolower($_FILES['image']['name']));
Someone was asked about overlapping subclusters in GraphViz and got the following response:
Sorry, no. General subgraphs can share nodes without implying subset
containment but not clusters. The problem is in the drawing.
If clusters can overlap arbitrarily, drawing them becomes the problem
of drawing Venn diagrams, for which there are no good algorithms.
What is a formal definition or example of the "problem of drawing Venn diagrams"?, and why is it (I assume NP-complete/hard) hard ? (Extra points: Sketch a reduction to a well-known NP-complete problem)
It is my understanding that iOS uses ICU under the hood. I'd like to access the functionality of ICU's MessageFormat for strings involving numbers and plurals, for example,
There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.
Does iOS expose this capability? If so how do I use it? I thought I might be able to write
[NSString stringWithFormat: "There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.", n];
or
[NSString stringWithFormat: "There {0,plural, =0{are no files}=1{is one file}other{are %ld files}}.", n];
But these formats (ICU4J and ICU, respectively) do not work.
I am trying to add a sub category to Messages in my xml statement Is there a way I can do this GroupMessages -> Message -> GroupMessage :
var groups = xDoc.Descendants("Group")
.Select(n => new
{
GroupName = n.Element("GroupName").Value,
GroupHeader = n.Element("GroupHeader").Value,
TimeCreated = DateTime.Parse(n.Element("TimeAdded").Value),
Tags = n.Element("Tags").Value,
Messages = n.Element("GroupMessages").Value
//line above
})
.ToList();
In my method GroupMessages contains both MessageID and GroupMessage and it is listing both in my datagrid within the one container. So I tryed this but it lists nothing:
Messages = n.Descendants("GroupMessages").Select(nd => nd.Element("GroupMessage").Value)
My xml looks like this:
<Group>
<TimeAdded>2012-04-27T10:23:50.7153613+01:00</TimeAdded>
<GroupName>Group</GroupName>
<GroupHeader>Header</GroupHeader>
<GroupMessages>
<Message>
<MessageID>1</MessageID>
<GroupMessage>Message</GroupMessage>
<MessageGroup/>
</Message>
</GroupMessages>
</Group>
I have also tryed:
Messages = n.Descendants("GroupMessages").Select(nd => nd.Descendants("Message").Select(nde => nde.Element("GroupMessage").Value))
To no avail?
I'm trying to find the best algorithm for
converting an "ordinary" linked list
into an `ideal skip list`
.
Where the definition of an ideal skip list is that in the first level we'll have all
the elements , in the level above - half of them , the one after - quarter of them ... and so on .
I'm thinking about O(n) run-time where involving throwing a coin for each node in
the original linked-list , whether or not for a specific node , should I go up or not , and create another duplicate node for the current node upstairs ...
Eventually this algorithm would produce O(n) , is there any better algorithm ?

I am unsuccessfully trying to populate a UITable from a NSMutableArray that contains a custom object.
My Student object
Student {
NSString name,
int age
}
In UITableView there is a method that displays the row's content:
cellForRowAtIndexPath
{
// there is more code here
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
}
Should my Student class implement a method that returns a String representation of the object? And then how can I display the content of the NSMutableArray in the UITableView.
Any help will be appreciated.
I have had a look about the site and found some code and tried it out but its not working in any shape or form.
I am wanting to count the number of DIVs thats placed into another DIV by the user dragging and dropping but only to count the 'correct' ones then if all the correct ones are in the DIV display an alert saying well done then rest the 'game'. Also need to show how many more is needed to go to 'win'.
This is what I have so far:
JS:
$('.drop').each(function(){
var n = $(this).children('.draggable').length;
$(".count").text("There are " + n + " divs inside parent box detail.");
if(n == 2){
alert("You got them all right! :)");
}
});
HTML:
<div class="foods">
<div class="draggable" id="draggable"><img src="images/fish.png" id="draggable"></div>
<div class="draggable" id="draggable"><img src="images/stone.png"></div>

I just installed python, mplayer, beautifulsoup and sipie to run Sirius on my Ubuntu 10.04 machine. I followed some docs that seem straightforward, but am encountering some issues. I'm not that familiar with Python, so this may be out of my league.
I was able to get everything installed, but then running sipie gives this:

I looked through these files and the line numbers, but since I am unfamiliar with Python, it doesn't make much sense. Any advice on what to do next?
I would like to dedicate this page to handling sessions using procedural php.
I'll begin with how I start most of my projects:
session_name('Easy_App');
session_start();
if (!isset( $_SESSION['ip'] )){
$_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];
}
if (!isset( $_SESSION['created'] )){
$_SESSION['created'] = time();
}
if (!isset( $_SESSION['overall_views'] )){
$_SESSION['overall_views'] = 1;
}
else {
$_SESSION['overall_views']++;
}
if (!isset( $_SESSION['username'] )){
$_SESSION['username'] = "";
}
if (!isset( $_SESSION['logged_in'] )){
$_SESSION['logged_in'] = 0;
}
/*A quick method to keep pageviews to < 5 pages per 1 second per session*/
if (!isset($_SESSION['first_action'])){
$_SESSION['first_action'] = time();
}
$first_action = $_SESSION['first_action'];
if (!isset( $_SESSION['action'] )){
$_SESSION['action'] = 1;
}
else{
$_SESSION['action']++;
}
$action=$_SESSION['action'];
if ($action>=5){
unset($_SESSION['action']);
unset($_SESSION['first_action']);
if((time() - $first_action) <=1){
exit("Please Don't Hammer My Site ");
}
}
So We have a starting point:
My question is this:
Where would you go from here? Improvements of the above code or a brief snippet of how you handle sessions using procedural php would be greatly appreciated.
its simple my doubt.
The app have 4 directories(ldpi, mdpi, hdpi, xhdpi) with same images but different dpi . For mdpi is 160dpi, the one im using atm.
What happens with the images i download from the web? i have a news reader and that means each new have one image at least. And i want to have a decent image for all the smartphones.
Do i need different type of images or just download the same for all?
Can i know which resolution is best for each particular smartphone?
I couldn't find the "official" way to handle this so i dont know if its important dpi for images that we plan to download.
Regards!
I am currently having trouble identifying and understanding the complexity time of the following algorithm.
Background: There is a list of files, each containing a list of candidate Ids. Both, number of files and number of candidates within them are not fixed.
How would you calculate the time complexity for an algorithm which is responsible for:
Reading each file and adding all the unique candidate Ids into a Hashset?
Thanks.
Okay, the Title is a bit vague, but what I'm trying to do is download data online, parse it and then put the parsed 'data' into an excel file.
I'm getting stuck in trying to put the data into a vector or list. Note that, the data can be either words or numbers. Also, I the length of the data is unknown. I tried the code below:
class MyHTMLParser(HTMLParser):
def handle_data(self, data):
d=[]
d=d.append(data)
parser = MyHTMLParser()
parser.feed('<html><head><title>Test</title></head>'
'<body><h1>Parse me!</h1></body></html>')
d
Traceback (most recent call last):
File "<pyshell#34>", line 1, in <module>
d
NameError: name 'd' is not defined
I looked around the forum for an answer, but didn't seem to encounter anything. I am a beginner, so may I'm missing something basic? Thanks, for the help...

Hello i'm trying to make a simple review function on ruby on rails. i have create a scaffold with the following attributes
event_id:integer name:string review_text:text no_starts:integer
Then i made this change on the show (view) of my event
:review, :action => :new, :id => @event.id %>
now i configured the routes fine and on the controller of the review i made this changes.
on the new i have added this
@review = Review.new(:event_id => params[:id])
and removed this
@review = Review.new
Then the page loads the event id it cites on the page but when i'm trying to save it is not stored. i thing the problem is when i move from the new method to create it doesnt transfer the id of the event thats why but i'm still what i'm doing wrong in the new?
I cannot get to update the field values of a content provider as a function of current field values.
For a single column, I try to do
...
ContentValues values = new ContentValues();
values.put(TableInOut.INOUT, TableInOut.INOUT + " + 1"); (*)
int numRowsUpdated = getContentResolver().update(TableInOut.CONTENT_URI_PRESENCE, values, "time_details > lastSafeEpoch.toString()", null);
values.clear();
...
LogCat says that numRowsUpdated are the expected ones, but there is no update?!
Any ideas please?
(*)
No luck even with these
values.put(TableInOut.INOUT, "88 + 1");
values.put(TableInOut.INOUT, "\"" +TableInOut.INOUT + "\"" + " + 1");
These work, but they do not use current values
values.put(TableInOut.INOUT, 77);
values.put(TableInOut.INOUT, "77");
