![enter image description here][1]
The reason for the Nominated table is that I realised that one nomination would have many nominees. For example, the award `Best Screenplay` could go to `Ken Levine and David Isaacs` or `Woody Allen` or `Joss Whedon, Andrew Stanton, Joel Cohen and Alec Sokolow`.
Thanks for pointing out any possible improvements.

I was hoping to add in a precommit hook to ensure before a commit is done locally (and pushed) each person has an up to date repo.
For instance, in CVS everyone would do a 'cvs up' before making changes, and then committing. I want to force it so people can't commit changes unless they have done a 'git pull origin master' first (we won't be using extra branches)
Is there an easy way to do this? cheers for any help :) | git | hook | pre-commit-hook | null | null | null | open | git precommit hook to ensure HEAD is up to date from master repo

What I'm looking for is a Linked List variant for Java I can iterate over, but which has something of a fixed length in a way.
You see, I want to track a ground path of simulated satellite in Kerbal Space Program, with data I get from a Telemetry Plugin. But I only want to display the ground path over the last about two hours. Now the entire data would be written into the Linked List, but as time goes by the list grows longer and longer and eventually its so large that it takes longer to iterate over this list to get the data of the last two hours of the orbit then it takes for a new set of data to come in.
So the Linked List variant I'm looking for would be of a somewhat fixed length that deletes the last entry(entries) if the time between the eldest and the newest entry are over two hours mission time. So that I only have to iterate over a relatively low number of entries and not the entire dataset of the previous flight (which is saved to bump it to CSV).
I appreciate any help that may be rendered by the helpful people around here. | java | null | null | null | null | null | open | Seeking LinkedList variant of fixed length, sort of

I tried with android.os.Handler but the problem with this Object is that it is running in the ui thread, so when the connection takes to much time the UI freeze...
The only way that I found to do this is to use asynctast and in onPostexecute() call again to the same Asynctask Object, something like that:
public class ScheduledAsyncTask extends AsyncTasc<Void..., Void..., Void..> {
doInBackground() {
Thread.sleep(30000); //30 seconds...

onPostExecute() {

This works great but I assume is not the best way to do it. All suggestions are welcome.

Background:
I am trying to add data to a SQL DB with C#. I am currently doing so in my script in another class so im using the same code (the code works). However, my current class is using a bunch of recycled code and i am having issues narrowing down why i can not write to the DB. Below is the code i am using and it is broken down to the bare bones minimum code.
What I'm asking for:
anyone to point out some dumb mistake i made or ideas where to troubleshoot. Currently i am just staring at this code and cant see whats wrong.
Thanks in advance!

`LayoutListener` only knows about `LayoutClass`
I can create the ActionListeners for the buttons fine because the buttons are actually created with the class, however because the textarea isn't actually created until the cell is clicked I can't set a focus listener from `LayoutListener` .

I am wondering now if it is possible to use the same algorithm to fill the circles?
Take the following few circles for example: http://imgur.com/S0Qy6 which are plotted with the following algorithm:
void circle(Point p, int r) {
int x = 0;
int y = r;
int f = 1-r;
// plot vert/horiz points indepedently
while (x<y) {
x++;
if (f<0) {
f += 2*x+1;
} else {
y--;
f += 2*(x-y+1);
}
glRecti(p.x+x, p.y+y, p.x+x+1, p.y+y+1);
// plot other points using 8 way symmetry
// attempt to fill the circle - didn't go well
plotLine(Point(p.x, p.y+x), Point(p.x+x, p.y+x));
}
}
I think the best place to put the filling bit would be in my main loop, as I want to essentially fill each quadrant again via 8-way symmetry. So I added my plotLine call, but what I ended up with was a strangely filled circle instead: http://imgur.com/jQW7B
If I then color the circles differently, I end up with horizontal banded stripes rather than actual filled circles - my approach is obviously wrong, but I'm not sure how to fix it. | c++ | algorithm | null | null | null | null | open | "Bresenham's" circle algorithm filling question

The problem is that i have no knowledge on web and i do not know how does it work , but i tried a sample :
Created a class :
public interface IFoo
{
string Bar { get; set; }
}
public class Foo : IFoo
{
public string Bar { get; set; }
}
Then
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public IFoo CreateFoo()
{
return new Foo() { Bar = "somevalue" };
}
public string Bar(IFoo foo)
{
return foo.Bar;
}
}
And Javascript Code :
<script type="text/javascript" language="javascript" >
function Callme(){
alert('Js function start . keep pressing OK')
var foo = external.CreateFoo();
alert(foo.Bar);
foo.Bar = "qwer";
alert(external.Bar(foo));
}
</script>
I get Error from the webbrowser control :
Error : "external" is null or not an object
But the javascript is not showing anything , please guide me if i missed something.

I have a form and I add in VS a timer control. I also have a class that is watching for an application to start (notepad.exe). When the event arrives it is supposed to enable the timer, set the interval and on each tick do something (like firing a messagebox or changing a label). This seems not to be happening. A look in the code make help someone give me a clue. The code is below:
public partial class Monitor : Form
{
EventWatcher eventWatch = new EventWatcher();
ManagementEventWatcher startWatcher = new ManagementEventWatcher();
ManagementEventWatcher endWatcher = new ManagementEventWatcher();
public Monitor()
{
InitializeComponent();
startWatcher = eventWatch.WatchForProcessStart("notepad.exe");
endWatcher = eventWatch.WatchForProcessEnd("notepad.exe");
}
private void appTimer_Tick(object sender, EventArgs e)
{
label1.Text = "tick";
MessageBox.Show("Tick");
}
}
And the watcher class is
class EventWatcher
{
public ManagementEventWatcher WatchForProcessStart(string processName)
{
string queryString =
"SELECT TargetInstance" +
" FROM __InstanceCreationEvent " +
"WITHIN 2 " +
" WHERE TargetInstance ISA 'Win32_Process' " +
" AND TargetInstance.Name = '" + processName + "'";
// The dot in the scope means use the current machine

I noticed two things:
When notepad.exe starts and I have the MessageBox.Show("notpad started"); line commented out the messabox in the timer tick event won't fire. If it is as displayed above it will show me both messaboxes (notepad started and tick). However the label1.Text will not change no matter what.
I am not sure what I am doing wrongly. I am sure it has something to do with how the timer event is handled but I am not sure what I should be doing. Any ideas?

I must be doing something completely wrong but I cannot figure it out. I have a form and I add in VS a timer control. I also have a class that is watching for an application to start (notepad.exe). When the event arrives it is supposed to enable the timer, set the interval and on each tick do something (like firing a messagebox or changing a label). This seems not to be happening. A look in the code make help someone give me a clue. The code is below:
public partial class Monitor : Form
{
EventWatcher eventWatch = new EventWatcher();
ManagementEventWatcher startWatcher = new ManagementEventWatcher();
ManagementEventWatcher endWatcher = new ManagementEventWatcher();
public Monitor()
{
InitializeComponent();
startWatcher = eventWatch.WatchForProcessStart("notepad.exe");
endWatcher = eventWatch.WatchForProcessEnd("notepad.exe");
}
private void appTimer_Tick(object sender, EventArgs e)
{
label1.Text = "tick";
MessageBox.Show("Tick");
}
}
And the watcher class is
class EventWatcher
{
public ManagementEventWatcher WatchForProcessStart(string processName)
{
string queryString =
"SELECT TargetInstance" +
" FROM __InstanceCreationEvent " +
"WITHIN 2 " +
" WHERE TargetInstance ISA 'Win32_Process' " +
" AND TargetInstance.Name = '" + processName + "'";
// The dot in the scope means use the current machine
string scope = @"\\.\root\CIMV2";
// Create a watcher and listen for events
ManagementEventWatcher watcher = new ManagementEventWatcher(scope, queryString);
watcher.EventArrived += ProcessStarted;
watcher.Start();
return watcher;
}
public void ProcessStarted(object sender, EventArrivedEventArgs e)
{
Monitor monitor = new Monitor();
//set timer interval and start time for Monitor class. (form)
monitor.appTimer.Interval = 5000;
monitor.appTimer.Enabled = true;
MessageBox.Show("notepad started");
}
}

I think this is happening because the JDialog is opened on top of an AWT component (it's a 3rd party component that uses an AWT Canvas, and I can't change that). If I open the dialog and close it over a swing component, then it works properly.
I've tried adding a window listener to the dialog and repainting the entire frame (using repaint and paintImmediately) when the dialog closes, but this doesn't work. Any suggestions on how to fix this?

A sample url of such kind is http://localhost:8000/customer/unsubscribe/%F1%CDE%A2%9DL%BF%21W%60%FF%04%D2%D2%3B%B1%FB%C9%8Ff%89%06O%FFY%E2_%16%9BnPM/.

<LinearLayout
android:id="@+id/homeButtonLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/p_buttons_background"
android:orientation="vertical" >
<ImageButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10px"
android:background="@drawable/home_icon"
android:onClick="goBackToCameraScreen" />
</LinearLayout>
I put a background around the ImageButton **in the LinearLayout**, as you can see above.
I want to be able to change that background (that is, **the background of the LinearLayout**, not the background of the ImageButton) when the user clicks on the ImageButton. I could do that programmatically, but I want to do that via XML. I could easily change the background **of the ImageButton** by writing a selector, like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/button_pressed" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="@drawable/button_focused" /> <!-- focused -->
<item android:drawable="@drawable/button_normal" /> <!-- default -->
</selector>
That's ***EXACTLY*** what I want, except that I want to **change the LinearLayout background, and not the ImageButton background**. How can I create a XML selector just like the one above, but that actually changes the background of the LinearLayout instead of the ImageButton background??

internal static class PluginDirectoryLoader
{
public static PluginInfo[] ListPlugins(string path)
{
var name = Path.GetFileName(path);
var setup = new AppDomainSetup
{
ApplicationBase = path,
ShadowCopyFiles = "true"
};
var appdomain = AppDomain.CreateDomain("PluginDirectoryLoader." + name, null, setup);
var exts = (IServerExtensionDiscovery)appdomain.CreateInstanceAndUnwrap("ServerX.Common", "ServerX.Common.ServerExtensionDiscovery");

}
catch
{
// to do
}
finally
{
AppDomain.Unload(appdomain);
}
return plugins ?? new PluginInfo[0];
}
}
The `path` parameter points to a subdirectory containing the plugin assemblies to load. The idea is to load them using a separate AppDomain with shadow copying enabled.
In *this* case, shadow copying isn't really necessary seeing as the AppDomain is unloaded quickly, but when I actually load the plugins in the next block of code I intend to write, I want to use shadow copying so the binaries can be updated on the fly. I have enabled shadow copying in this class as a test to make sure I'm doing it right.
Apparently I'm not doing it right because when I break in the debugger on the commented line in the code sample (i.e. `plugins = exts.ListPlugins()`), the original plugin assemblies are locked by the application!
Seeing as I'm specifying that assemblies loaded by the AppDomain should be shadow copied, why are they being locked by the application? | c# | .net | reflection | appdomain | null | null | open | AppDomain shadow copying not working (original assemblies locked)

I have a javascript-based client that is currently polling a .NET web service for new content. While polling works...I'm not happy with this approach because I'm using system resources and creating overhead when there aren't any changes to receive.

- some automated checks would need to be made before a
new discussion is allowed to be created (such as examining the contents of any URLs within the message)
- would need to do some automated deletion or archiving of
discussions based on criteria such as the discussion containing broken or expired URLs
From what I have read phpBB would not be ideal for this but Joomla or Drupal could be better? I have fairly good programming skills.

Previously I implemented a singleton CameraControl class. This class controls a camera which is connected to the system. Under the following knowledge:
* Under no circumstance will there be more than one camera (the camera API provided by the camera maker control all cameras).
* Using the API of the camera maker in multiple places at the same time have caused problems in the past (e.g. one thread trying to grab an image, the other thread trying to set the shutter speed).
* My class only provides several extra methods to display the image captured in a UI. Forward the image to a face detector, ... (i.e. it is not memory intensive).
Is my choice of making this class a singleton class a bad decision? | c++ | design-patterns | singleton | null | null | null | open | Guarding resources with Singleton?

My first goal is to make a simple app that:
- Displays a 3D cube in the center of the screen.
- And move the camera around the cube as you drag your finger.
I want something very simple: no texture, no background, just a cube that can be rotated with touch event. And the rotation can juste be horizontal and vertical.
Where should I start to be able to do this app? I'm searching for some tutorials or exemples.

fact 0 = 1
fact n = n * fact(n-1)
seems to be local type inference. Type inference here is local to function fact.
So, I wonder, is there a practical example of at least 2 mutually recusive functions or any other non-locality at your discretion that has some benefit from type inference? Please do not post a silly examples like
odd 0 = false
odd n = even(n-1)
even 0 = true
even n = odd(n-1)
I suspect that non-silly, practical examples arise in parses. Also, please point a benefit for a programmer to such use of non-local type inference.
