2,242,722 | 1 | 2,242,825 | null | 1 | 202 | I understand threads in theory, but I have no idea how to implement them in Java.
The circles are supposed to be threads and the rectangles are supposed to be buffers.
I have this all coded but it doesn't work, so I am starting new. My source of confusion comes from the fact that I need this cycle to repeat many times and in this order, but I can't predict what thread will run first. If thread B that relies in data from A runs first, what happens?
Also how can I keep the threads running indefinitely?

I have managed to get pretty far but there is something I can't figure how to approach to.
Currently I have this:
[Link to full size screenshot](https://farm5.static.flickr.com/4070/4348395096_68dd5d7785_o.png)
As you can see, I don't know how to place things where I want them.
At this point just stacking the buttons (sleep timer and message text) and the input-spinner at the top of each panel would suffice, but I would like to learn how to control this better. (Place each component at a chosen location inside the panel)
The JSP code:
```
<h:panelGrid id="ActionsPanel" styleClass="leftcol"
binding="#{actions.actionPanel}">
</h:panelGrid>
<h:panelGrid id="EditPanel" styleClass="rightcol"
binding="#{actions.editorPanel}">
</h:panelGrid>
```
And the CSS:
```
.leftcol {
display: block; width : 20%;
height: 300px;
float: left;
border: 1px solid #000;
width: 20%; height : 300px; float : left; border : 1px solid #000;
border-top: 0;
}
.rightcol {
width: 70%;
height: 300px;
float: left;
border: 1px solid #000;
border-top: 0;
border-left: 0;
}
```
Thanks!
Ben.

2,243,607 | 1 | 2,348,632 | null | 1 | 1,847 | I'm developing an application which draws some charts and I'm using Google Chart. After I have all the needed data I build the URL dinamically. The problem is that Google Chart doesn't always fix the maximum and minimum of the chart to the values I provide. I calculate Max and Min Values based on the data of the cart. I've set them to be always an integer to avoid any problem.
I'm going to set an example with numbers:
(I write it in different lines with "comments (//)" so it can be read easily, though it is in the same line with any comment at all)
```
http://chart.apis.google.com/chart?
cht=bvs& //chart type
chs=250x250& //chart size
chd=t:10,0|4.48,0|15,-58.42|0,4.73|0,73.44& //chart data
chco=4D89D9,C6D9FD,FF0000,00FF00,0000FF& //chart colors
chds=-59,80& //data scaling
chf=bg,s,edf5ff|c,s,f6e426& //chart fill color
chtt=my_title& //chart title
chdl=A|B|C|D|E& //chart legend
chdlp=r& //legend position
chxt=x,y& //chart axis
chxl=0:|Col_1|Col_2& //Axis labels
chxr=1,-59,80& //Axis range
chbh=r,1,0& //Bar thickness and spacing
chg=0,12.5 //Grid Lines
```
with this configuration I'd get this chart. As you can see the zero line is over zero because data has not been scaled isn a good way.
but If I change the maximum and minumum of the chart to -60,80 I get it in a good way
It would be this code:
```
http://chart.apis.google.com/chart?
cht=bvs& //chart type
chs=250x250& //chart size
chd=t:10,0|4.48,0|15,-58.42|0,4.73|0,73.44& //chart data
chco=4D89D9,C6D9FD,FF0000,00FF00,0000FF& //chart colors
chds=-60,80& //data scaling (CHANGE IN THIS LINE)
chf=bg,s,edf5ff|c,s,f6e426& //chart fill color
chtt=my_title& //chart title
chdl=A|B|C|D|E& //chart legend
chdlp=r& //legend position
chxt=x,y& //chart axis
chxl=0:|Col_1|Col_2& //Axis labels
chxr=1,-60,80& //Axis range (CHANGE IN THIS LINE)
chbh=r,1,0& //Bar thickness and spacing
chg=0,12.5 //Grid Lines
```
And this chart which seems to be OK:
Can anyone tell me why Google Chart behaves in this way?
Thanks

2,244,599 | 1 | 2,247,119 | null | 3 | 3,679 | I'm building a first person shooter using OpenGL, and I'm trying to get a gun model to float in front of the camera. I've ripped a model from Fallout 3 using a resource decompiler (converted to .obj and loaded in).
However, this is what it looks like on the screen:
Half the gun's triangles are clipped to what appears to be the frustum.
I put it in front of my camera like this:
```
glPushMatrix();
glLoadIdentity();
glTranslatef(m_GunPos.x, m_GunPos.y, m_GunPos.z);
glRotatef(m_GunRot.x, 1, 0, 0);
glRotatef(m_GunRot.y, 0, 1, 0);
glRotatef(m_GunRot.z, 0, 0, 1);
glScalef(m_GunScale.x, m_GunScale.y, m_GunScale.z);
m_Gun->Render(NULL);
glPopMatrix();
```
So I save the original `GL_MODELVIEW` matrix, load the identity matrix, translate my gun to be slightly to the right of my camera and render it. This is my render routine for a SceneNode:
```
glPushMatrix();
if (m_Model) { m_Model->Render(&final); }
if (m_Children.size() > 0)
{
for (std::vector<SceneNode*>::iterator i = m_Children.begin(); i != m_Children.end(); ++i)
{
(*i)->Render(&final);
}
}
glPopMatrix();
```
So it renders its own model and any child SceneNode's. Finally, the actual mesh rendering looks like this:
```
if (m_Material)
{
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, m_Material->m_TexDiffuse);
}
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);
glVertexPointer(3, GL_FLOAT, sizeof(Vec3), &m_Vertex[0]);
glNormalPointer(GL_FLOAT, sizeof(Vec3), &m_Normal[0]);
glTexCoordPointer(2, GL_FLOAT, 0, &m_UV[0]);
glDrawArrays(GL_TRIANGLES, 0, m_Vertex.size());
glDisableClientState(GL_NORMAL_ARRAY);
glDisableClientState(GL_TEXTURE_COORD_ARRAY);
glDisableClientState(GL_VERTEX_ARRAY);
```
Is there any way to turn off clipping for just the gun? How do other games do this?
Thanks in advance.

2,245,235 | 1 | null | null | 9 | 9,499 | I use a simple ASP.NET MVC web (the template you use when you create a new site) and the web works as expected in my live environment.
I now try to use IIS Application Request Routing version 2. I have a rule that send all requests to a different server that match a rule.
The settings are a bit like this: [http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx](http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx)
My rule is just a bit different it is /shop(.*).
Only requests that contain shop are send to a different server. I have to use rewrite, not redirect (The same as in the Picture)
This works as long as the original requests go to a non ASP.NET MVC web. I tried to use a plain htm file in the webfolder and it worked. If put a compiled ASP.NET application into the webfolder it worked. But as soon as I put an ASP.NET MVC web into the folder, request arr served by this application.
My understanding is that the ARR should kick in before the web application gets the chance to handle the request.
Did anybody use ARR sucessfully as a reverse proxy for a ASP.NET MVC web?
Here is the resulting web config when the rewrite roule is entered. With this rule I get a 404 that indicates that the rule is not used.

2,247,063 | 1 | 2,247,212 | null | 6 | 9,342 | I am trying to trace the path of a node in a binary tree (not a binary search tree). Given a node, I am trying to print the values of the path from the root.
I have written the following program.
```
package dsa.tree;
import java.util.Stack;
public class TracePath {
private Node n1;
public static void main(String args[]){
TracePath nodeFinder = new TracePath();
nodeFinder.find();
}
public void find(){
Tree t = getSampleTree();
tracePath(t,n1);
}
private Tree getSampleTree() {
Tree bsTree = new BinarySearchTree();
int randomData[] = {43,887,11,3,8,33,6,0,46,32,78,76,334,45};
for(int i=0;i<randomData.length;i++){
bsTree.add(randomData[i]);
}
n1 = bsTree.search(76);
return bsTree;
}
public void tracePath(Tree t, Node node){
trace(t,node);
}
Stack<Node> mainStack = new Stack<Node>();
public void trace(Tree t, Node node){
trace(t.getRoot(),node);
}
private void trace(Node parent, Node node){
mainStack.push(parent);
if(node.data == parent.data){
for(Node iNode:mainStack){
System.out.println(iNode.data);
}
return;
}
if(parent.left != null){
trace(parent.left, node);
}
if(parent.right!=null){
trace(parent.right, node);
}
mainStack.pop();
}
}
```
I am getting the output properly. But its kind of messy. If you see the method trace(Node, Node), I am printing the values which I should not do. I want the trace method to properly complete. At least, I should kill the recursive structure at the stage i encounter the if condition.
Please advise.

2,247,778 | 1 | 2,248,168 | null | 2 | 1,566 | I'm having amazing difficulties with a high-precision pixel-oriented image program in WPF and starting to suspect that the `Cursors.Cross` cursor hotspot is not at its centre, as you would expect.
I'm debugging using [Magnifier](https://www.microsoft.com/enable/training/windowsvista/magnifier.aspx) at 16x and mouse set to the lowest acceleration. The code is based on [DrawTools from CodeProject](https://www.codeproject.com/KB/WPF/WPF_DrawTools.aspx).
Is this the same cursor as you get in Winforms? If so, I can look at that cursor's hotspot - the [Cursor](https://msdn.microsoft.com/en-us/library/system.windows.input.cursor.aspx) class in System.Windows.Input doesn't have the HotSpot property.
UPDATE
In case anyone is looking for a workaround, in my case I already have a delegate being invoked to filter the points so I can implement snap-to-grid behaviour. It was trivial to offset the point by 1 to compensate. This was a lot easier than creating a custom cursor and has the advantage that I'm still using the stock cursor if its appearance should change.

2,250,606 | 1 | 2,250,772 | null | 3 | 1,102 | I've built a UserControl that extends the functionality of the ComboBox in interesting and useful ways. It looks like this when it's dropped down:
I've built a whole bunch of features into the control and they all work smoothly. This leads me to believe that I have something of a clue as to what I'm doing. You'd think it would be a trivial matter to have the UserControl's style set the editable TextBox's background brush. In fact, it appears to be freaking impossible. And I'm baffled.
The UserControl's XAML, abbreviated (you'll thank me for this), looks like this:
```
<UserControl x:Class="MyApp.CodeLookupBox" x:Name="MainControl">
<UserControl.Resources>
<!-- tons of DataTemplates and Styles, most notably the style that
contains the control template for the ComboBox -->
<UserControl.Resources>
<ComboBox x:Name="ComboBox"
Margin="0"
Style="{DynamicResource ComboBoxStyle1}"
VerticalAlignment="Top"
ItemTemplate="{StaticResource GridViewStyleTemplate}"/>
</UserControl>
```
There's a lot of code-behind in this control, mostly dependency properties that I use for things like selecting the template that's used in the dropdown.
What's making me crazy is the editable text box. I want to be able to set its background brush from the user control's style - e.g., when I declare one of these user controls in my XAML, it uses a style like this:
```
<Style TargetType="{x:Type local:CodeLookupBox}">
<Style.Triggers>
<DataTrigger Binding="{Binding IsRequired}" Value="True">
<Setter Property="EditableTextBoxBackground" Value="{StaticResource RequiredFieldBrush}"/>
</DataTrigger>
</Style.Triggers>
</Style>
```
I started out life simply setting the UserControl's Background, but that set the background the editable TextBox. The TextBox itself remained white.
Inside the template for the ComboBox, there's a style that controls that TextBox:
```
<Style x:Key="ComboBoxEditableTextBox" TargetType="{x:Type TextBox}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="MinWidth" Value="0"/>
<Setter Property="MinHeight" Value="0"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<ScrollViewer
x:Name="PART_ContentHost"
Focusable="false"
HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Hidden"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
```
And there is the TextBox (inside the ComboBox's control template) its bad self:
```
<TextBox
x:Name="PART_EditableTextBox"
Margin="{TemplateBinding Padding}"
Style="{StaticResource ComboBoxEditableTextBox}"
HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
IsReadOnly="{Binding IsReadOnly, RelativeSource={RelativeSource TemplatedParent}}"/>
```
Now, there's a definite element of Things Man Was Not Meant To Know about that ComboBoxEditableTextBox style. What is that ScrollViewer doing in there? I have no idea. I can tell you that if I comment out the part of the style that sets the TextBox's ControlTemplate, very bad things happen.
And I also know this: If I explicitly set the TextBox's Background brush as one of the style's setters, nothing happens. If I explicitly set the Background on the PART_EditableTextBox, nothing happens. (I can set its Foreground, or its FontFamily, and they work just fine.)
If I explicitly set the Background of that ScrollViewer to Green, though, voila, the TextBox turns green.
Okay then, so the TextBox is ignoring its own Background, and using the one from its control template. Actually, it's not, strictly speaking, using the one from the control template either. When I set the ScrollViewer's background, there's a decided margin around the edges of the color, instead of the color filling the TextBox entirely. But that margin is white, not the background color.
Unless I can figure out why the TextBox is ignoring its Background, I have to live with tweaking the ScrollViewer. So how do I get it to get the brush from the user control's EditableTextBoxBackground property? I've made this a dependency property that raises the PropertyChanged event properly when it changes. I'm binding to it in the mysterious ScrollViewer's XAML like this:
```
Background="{Binding ElementName=MainControl,
Path=EditableTextBoxBackground,
Converter={StaticResource DebuggingConverter}}"
```
I've set a breakpoint in my debugging converter. When the control is first drawn, it gets hit twice. The first time, the value of the brush is null. The second time, it's the right value. And if I set the property in my UserControl's , it works.
So here's what I know: My UserControl's property is being set properly. The binding on the TextBox's style is correctly bound to the UserControl's property. The binding on the ScrollViewer in the TextBox's control template is bound to the right property. The property raises PropertyChanged with the right property name when it's changed, and the binding pushes the value out to the ScrollViewer Background property.
And nothing happens.
So I guess I have a three part question: 1) Why? 2) What the heck is that ScrollViewer doing in there in the first place? I have my suspicions, but it's one in the morning and it's getting hard for me to articulate them. 3) Why did Blend give me a different control template to work with than the much more comprehensible one found [here](http://msdn.microsoft.com/en-us/library/ms752094.aspx)?
Really, any help would be appreciated.

I've used Photoshop to delete the pixels in the background all around the button image I'm using, then saved it as a GIF, and imported it into VS to use as the background image of my button. When windows XP renders it, it is fine, but when windows 7 renders it, all 4 corners have an odd white border around them.
You can barely see them in this pic, but they are much more apparent when looking at them on the client PC's.
Is there something wrong with the way I am transfering the image? should I not use a gif? is there something wrong with the way I am displaying it on the button? What can I do about it?

2,269,798 | 1 | 2,270,300 | null | 20 | 7,456 | In the past, I have used Vim as a note taking platform by creating an index.txt file with a list of tags using the Vim help file format and then creating a bunch of text files that have the normal `*Help_Tag*` link syntax so that using `CTRL-]` on a tag in the index.txt file will jump to the respective tag in an arbitrary notes text file. You need to do `:helptags dir` to generate the tags for the directory (where dir is the path to the notes directory).
What I am looking for is a simple way to be on the left split window and open the tag under the cursor in the right split window. Something like `CTRL-W v` but for tag jumping and using the already open vertical split window.
The problem is if you do `CTRL-]` it will open the tag in the left pane and if you do `CTRL-W CTRL-]` it creates a horizontally split window in the left pane.
There must be a way to do this that I'm overlooking.

Here's some basic info:
Language recognition (e.g. Japanese, English, German, etc) using acoustic features is an important yet difficult problem for current speech
technology. ... The speech data base used in this paper contains 20 languages: 16
sentences uttered twice by 4 males and 4 females. The duration of each
sentence is about 8 seconds. The first algorithm is based on the standard
Vector Quantization (VQ) technique. Every language is characterized
by its own VQ codebook, .
The first algorithm is based on the standard Vector Quantization (VQ) technique. Every language, `k`, is characterized by its own VQ codebook, . In the recognition stage input speech is quantized by  and the accumulated quantization distortion, d_k, is calculated. The language which as the minimal distortion is recognized. Calcualating VQ distortion, several LPC spectral distortion measures are applied...in this case, the WLR -- weighted least ratio -- distance: [](https://i.stack.imgur.com/t8QMQ.gif)
.
A codebook, [](https://i.stack.imgur.com/I40h5.gif)
, for each language is generated using training sentences. The accumulated distance for input vector in sentence, ![alt text][4], is defined as: [![alt text][5]][5]
The distance `d` can be any distance which corresponds to the acoustic features and it must be the same as the one used for codebook generation. Each language is characterized by its VQ codebook, .
My question is, how exactly do I do this? I have a set of 50 sentences in English. In MATLAB, I can easily calculated the WLR for any given signal. But, how do I formulate a codebook, since I must use the WLR for "codebook generation" for English. I'm also curious as to how to compare a VQ codebook of size 16 (which was found to be the best size), to a given input signal. If anyone could help distill this paper down for me, I'd appreciate it greatly.
Thanks!

The Child class has a reference to another parent class, Type. The relationship looks like
Due to this relationship, when the above code is called, instead of a DELETE query, an UPDATE query is generated which removes the ParentID from the Child table(sets to null).
Is it possible to force NHibernate to delete the child record completely, when removed from the Parent.Children collection?
@Spencer's Solution
Very attractive solution as this is something that can be implemented in future classes. However, due to the way sessions are handled(in my particular case) in the repository pattern, this is near impossible as we would have to pass session types(CallSessionContext/WebSessionContext) depending on the application.
@Jamie's Solution
Simple and quick to implement, however I've hit another road block. My child entity looks as follows:
When using the new method, NHibernate generates an update statement setting the TypeID and ParentID to null, as opposed to a single delete outright. If I missed something within the implementation, let me know as this method would be painless to move forward with.
@[The One-Shot-Delete solution described here](http://knol.google.com/k/fabio-maulo/nhibernate-chapter-16/1nr4enxv3dpeq/19#16(2E)5(2E)(C2)(A0)Understanding_Collection_performance), outlines an idea dereferencing the collection to force a single delete. Same results as above however, an update statement is issued.
```
//Instantiate new collection and add persisted items
List<Child> children = new List<Child>();
children.AddRange(parent.Children);
//Find and remove requested items from new collection
var childrenToRemove = children
.Where(c => c.Type.TypeID == 1)
.ToList();
foreach (var c in childrenToRemove) { children.Remove(m); }
parent.Children = null;
//Set persisted collection to new list
parent.Children = Children;
```
Took a bit of digging, but Jamie's solution came through with some additional modifications. For future readers, based on my class model above:
Type mapping - Inverse = true, Cascade = all
Parent mapping - Inverse = true, Cascade = all-delete-orphan
Remove methods as described in Jamie's solution works. This does produce a single delete statement per orphaned item, so there is the possibility for tuning in the future, however the end result is successful.

map.AddShape(points, Color.Red, "Bermuda Triangle");
}
```
You can see that the Bermuda Triangle overlays the map in red. Now I want to calculate a set of points to pass to my AddShape method that would draw an elipse or circle. I just need a simple algorithm for calculating the x and y coordinates of a given number of points. Perhaps starting with a given point that would represent the centre of the circle. For example:
```
public static void AddCircle(this MapControl map, Point centre, double radius, string name)
{
var points = new List<MapPoint>();
const int n = 360;
for(var i = 0; i < n; i++)
{
//calculate x & y using n, radius and centre
double x = 0;
double y = 0;
points.Add(new MapPoint(x, y));
}
map.AddShape(points, Color.Red, name);
}
```
I know that the x,y calculation is simple trigonometry but I'm suffering a brain freeze. Help!
EDIT (Solved using tur!ng's code):
```
public static void AddCircle(this MapControl map, Color color, MapPoint centre, double radius, string name)
{
var points = new List<MapPoint>();
const int n = 360;
for(var i = 0; i < n; i++)
{
var x = (radius * Math.Cos(i * Math.PI / 180)) + centre.X;
var y = (radius * Math.Sin(i * Math.PI / 180)) + centre.Y;
points.Add(new MapPoint(x, y));
}
map.AddShape(points, color, name);
}
```
The blue circle (over Greenwich) is distorted because of the map projection over a Robinson grid.

2,283,617 | 1 | 2,312,187 | null | 17 | 6,551 | I have an HTML table whose cells contain, among other things, spans, like this:
```
...
<td>
<span style="height: 20px; width: 20px; margin-left: 2px;">
<span style="height: 20px; width: 20px; margin-left: 2px;">
<span style="height: 20px; width: 20px; margin-left: 2px;">
</td>
...
```
I'm looking for a way to shrink the width of those spans, rather than line wrap them, when the containing table cell is too narrow to show them all on one line. I tried playing around with setting the spans' `max-width` to `20px` and then using a percent for the width, but that does not work because the table cell tries to be only as wide as its contents.
The minimum table cell width would be the width needed to display the header on 1 line.
For the visual types, here's what I currently have when there is enough width:
Here's what I currently have when there is not enough width:
And here's what I would like it to look like when there is not enough width for each span to be a full 20px:
In case it's not obvious, the spans are the colored squares in the `TXEs`, `RDBs`, and `RavenNets` columns.

2,283,923 | 1 | 2,284,591 | null | 1 | 8,388 | I am trying to change the value of the onblur attribute of a text input after the page has finished loading.
When I do the following, it simply fires the function:
`ip.onblur = stopCalcUpInt(this,10);`
When I do the following, I have success:
`ip.onblur = function onblur(event){stopCalcUpInt(this,10);}`
Unfortunately, the whole point of this is to be able to dynamically set the second parameter for stopCalcUpInt(). If I hard code a value for it... it works fine... but any attempts to pass varibles to this fails... instead of putting the value of the variable as the second param it just puts the plain text of the variable name itself. Here is ideally what I am TRYING to do:
`ip.onblur = function onblur(event){stopCalcUpInt(this,this.value);}`
In this example, when I alert the ip.onblur I get:

2,284,059 | 1 | null | null | 4 | 9,785 | I'm trying to build an app to detect images which are advertisements from the webpages. Once I detect those I`ll not be allowing those to be displayed on the client side.
From the help that I got on [this Stackoverflow question](https://stackoverflow.com/questions/1991113/optimization-of-neural-network-input-data), I thought SVM is the best approach to my aim.
So, I have coded SVM and an SMO myself. The dataset which I have got from UCI data repository has 3280 instances ( [Link to Dataset](http://archive.ics.uci.edu/ml/datasets/Internet+Advertisements) ) where around 400 of them are from class representing Advertisement images and rest of them representing non-advertisement images.
Right now I'm taking the first 2800 input sets and training the SVM. But after looking at the accuracy rate I realised that most of those 2800 input sets are from non-advertisement image class. So I`m getting very good accuracy for that class.
So what can I do here? About how many input set shall I give to SVM to train and how many of them for each class?
Thanks. Cheers. ( Basically made a new question because the context was different from my previous question. [Optimization of Neural Network input data](https://stackoverflow.com/questions/1991113/optimization-of-neural-network-input-data) )

Thanks for the reply.

2,290,992 | 1 | null | null | 2 | 2,584 | Have stumbled upon what seems to be a bug with how mobile safari renders the cursor when a window.scrollTo() is executed while a user is entering text into a textarea. Have attached source code which illustrates the issue. I'm wondering if anyone has any advice on how I might work around this.
If a user is entering text into a textarea and a window.scrollTo() is executed, the cursor remains rendered at the position the textarea to be, not at it's current position.
Load the following web page using mobile safari. Touch the textarea, which will open the keyboard. Type a couple of characters and wait. As text is added dynamically to the page, and the window scrolled, you'll see the cursor artifact
Have tried setting the focus() back to the textarea after the scroll, but that doesn't seem to have any effect.
Thanks!

What I'm not understanding is why it renders differently in Firefox occasionally. Sometimes it shows up like it's supposed to and sometimes it shows up in this weird format as seen here:
I've never had anything like this happen before, does anyone know what's causing it? Does it even do this for anyone else? Like I stated before, sometimes it loads just fine (exact same HTML, CSS, and everything) and sometimes it doesn't. It seems kind of random. It loads just fine in IE with no weird problems at all.

or
Is there a build-in way to filter the additional response header, whose size could vary depending on the HTTP-Server?

Here's a screen which says it all:
It prints `null` for the `/test.xml` resource. The `Class#getResourceAsStream()` obviously doesn't make any difference.
I checked the project's `/bin` folder and the XML file is indeed not there. I've checked all settings to see if there isn't some filter to exclude certain files from ending up in the `/bin` folder during the build, but all in vain.

2,303,690 | 1 | 3,223,466 | null | 336 | 313,915 | I'm trying to create a thumbnail image on the client side using javascript and a canvas element, but when I shrink the image down, it looks terrible. It looks as if it was downsized in photoshop with the resampling set to 'Nearest Neighbor' instead of Bicubic. I know its possible to get this to look right, because [this site](http://www.rigasa.ch/~labo/labo/pixastic/editor/) can do it just fine using a canvas as well. I've tried using the same code they do as shown in the "[Source]" link, but it still looks terrible. Is there something I'm missing, some setting that needs to be set or something?
EDIT:
I'm trying to resize a jpg. I have tried resizing the same jpg on the linked site and in photoshop, and it looks fine when downsized.
Here is the relevant code:
```
reader.onloadend = function(e)
{
var img = new Image();
var ctx = canvas.getContext("2d");
var canvasCopy = document.createElement("canvas");
var copyContext = canvasCopy.getContext("2d");
img.onload = function()
{
var ratio = 1;
if(img.width > maxWidth)
ratio = maxWidth / img.width;
else if(img.height > maxHeight)
ratio = maxHeight / img.height;
canvasCopy.width = img.width;
canvasCopy.height = img.height;
copyContext.drawImage(img, 0, 0);
canvas.width = img.width * ratio;
canvas.height = img.height * ratio;
ctx.drawImage(canvasCopy, 0, 0, canvasCopy.width, canvasCopy.height, 0, 0, canvas.width, canvas.height);
};
img.src = reader.result;
}
```
EDIT2:
Seems I was mistaken, the linked website wasn't doing any better of a job of downsizing the image. I tried the other methods suggested and none of them look any better. This is what the different methods resulted in:
Photoshop:
Canvas:
Image with image-rendering: optimizeQuality set and scaled with width/height:
Image with image-rendering: optimizeQuality set and scaled with -moz-transform:
Canvas resize on pixastic:
I guess this means firefox isn't using bicubic sampling like its supposed to. I'll just have to wait until they actually add it.

I'd prefer to enable it for a free-form project that I build using my own Ant build.xml, but I see no options to enable that, so I'm willing to go with a "Web Application with Existing Sources".
I just want to show what I did.
After setup and configuration, code-completion within facelets still doesn't work.
Am I missing something? Am I going about this in the wrong way?
# Solution
Here's what I ended up doing:
1. I switched from a Standard Java project to a Web project (duh!)
2. I took Awano's advice and switched the MIME type for xhtml files back to text/xhtml.
3. I added the tld file from the facelets site to the meta-inf directory in the jsf-facelets.jar and included it in my project.
4. I added the rendered attribute to the fragment tag in the jsf-ui.tld file. It was missing for some reason: <attribute>
<name>rendered</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
<description>Renders the contents of this tag if the attribute resolves to true.</description>
</attribute>

2,312,635 | 1 | 2,316,297 | null | 4 | 766 | I'm creating the database for monitoring status of applications' functionalities. The logic is following:
Each application has its own, specific list of functionalities that I'm monitoring. Each functionality belongs to only one application. There is a Functionality table that has foreign key to Application
Each application runs on one or more machines. Each machine can run one or more applications. This is MTM connection, so there is ApplicationInstance table connection Applications with Machines.
The actual monitoring is about querying ApplicationInstance. If there is a problem, information about it goes to AppInstanceError table, wich holds foreign key to ApplicationInstance. If the query is successful, we get a list of statuses of each functionality. So we have a FunctionalityStatus table with foreign keys to ApplicationInstance & Functionality.
I think this is kind of bad design - why do we have multiple reference to Application? What guarantees that both will point to the same Application? Or is there any way to ensure this?
So my proposition of fix is to connect FunctionalityStatus with foreign keys to Machines & Functionality. But in this case they define ApplicationInstance so what is the guarantee of having ApplicationInstance for each pair? Shouldn't they be connected somehow? In the real world connection exists and is obvious, so is it OK not to have it in database?
Is there a "propper way" of solving this problem, or of ensuring connections invisible from data design?
To make it more clear I prepared design of DB that I have now:
The only thing that is missing is a connection from FunctionalityStatus to Machine. I see two ways ow making such a connection:
1. Add foreign key to ApplicationInstance - then my doubts are: How to make sure that ApplicationId from Functionality is the same that one from ApplicationInstance? Isn this data duplication really needed?
2. Add foreign key to Machine - and doubts: Will there be a propper ApplicationInstance record for every FunctionalityStatus record? If there is an obvious connection between ApplicationInstance and FunctionalityStatus (mentioned in first doubt) whu can't we see it in database? Again data redundancy becouse all ApplicationInstance records are (or should be) visible in FunctionalityStatus table
Or maybe the whole design is screwed up and I should figure out something totally else?

2,313,830 | 1 | null | null | 1 | 1,087 | I can't seem to get a handle on my list of sortables. They are a list of list elements, each with a
form inside, which I need to get the values from.
```

var serial = [];
this.list.getChildren().each(function(el, i){

if (order[i]) {
//alert(order[i].substr(5, order[i].length));

the sortables list is then added to a list in a loop with `sort.addItems(li);` . But when I try to get the sortables outside of the sortables onComplete declaration, js says this.list is undefined.

Trying to loop through the DOM gives me equally bizarre results. Here are the firebug console results for some code:
```
var a = document.getElementById('teams').childNodes;
var b = document.getElementById('teams').childNodes.length;
try {
console.log('myVar: ', a);
console.log('myVar.length: ', b);
} catch(e) {
alert("error logging");
}

Trying to get the objects with `document.getElementById('teams').childNodes[i]` returns undefined.
thank you for any help!

I am not sure if its because I have the image in the wrong location. but if that was the case. I figure it would throw a error. I have the image placed at the root of my source folder.

2,314,847 | 1 | null | null | 1 | 2,556 | I am trying to develop a website with C# ASP.net MVC. It's my first time using Visual Studio, C# and ASP.net so I have lots to learn but so far so good.
So far... I started a C# ASP.net MVC project and added a database by going to the Database Explorer and clicking "add connection". I then did some standard CRUD controllers and views.
I am at the stage where I want to implement User authentication. I'm a bit confused here. I am trying to make a custom Membership Provider. So I added it to my web.config file with the correct connection string etc.
When I run the project and go to register I get an error. "Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'."
From searching, I see lots of people have this problem and they always reference their hosting. People say this ([http://weblogs.asp.net/scottgu/archive/2005/08/25/423703.aspx](http://weblogs.asp.net/scottgu/archive/2005/08/25/423703.aspx)) is their solution but when I try pick a database I get an error. Not even sure of my server name.
So at this point I am wondering, did I set up the database right?
Adding in a few pics to show exactly what I am doing. This is the aspnet_regsql.exe:
This is the provider with connection string, taken from an example on one of the links given.
This is my customized provider with connection string pointing to the last image.
This is a screen cap when I run the project and go to the default project Account register action:
and finally, this is the error screen when I submit
Another update..
I sorted something out but I am not sure if it is correct. I am now getting an error when the page loads: "Invalid object name 'dbo.Tag'"

I'm currenly passing form object to VIEW and echo every elemen manually.
But when comes to errors, it takes a lot of code to write.
Could someone tell, how to output errors for each element without such amount of code?

From what I've read around different sites, I should use a triangulation algorithm to make meshes of the walls of the cave (the black part) using the polygon of the inside of the cave (the white part).

2,346,129 | 1 | 2,349,245 | null | 1 | 1,331 | This relates to both physical programming as well as Ruby running on a web server. I have an array of RGB leds, which is 5x5 so a total of 25 leds. They are numbered and individually addressable as such:
```
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20

Here is a photo:
As for the hardware (which really isn't important, because it works fine), the system consists of 25 [BlinkM](http://thingm.com/products/blinkm)'s, an [Arduino](http://www.arduino.cc/), and some various cabling and connectors.
The led's are sent commands via serial with a command as such:
```
@sp.write ["\x01", led, "\x04\x00", "c", color]
```
Which writes the byte array out to serial using ruby's [Serialport gem](http://github.com/hparra/ruby-serialport), the variables "led" and "color" are substituted with the hex of each, so for example if I wanted to make led number 8 turn red, my output would read:
```
@sp.write ["\x01","\x08", "\x04\x00", "c", "\xff\x00\x00"]
```
So far all of this works wonders, and I'm really happy with what I have, now my question relates pretty much to general mathematics and simple programming, but somehow the implementation goes over my head.
[Here is a sample of such animation.](http://www.youtube.com/watch?v=GeBMQ4zCvNI) Mostly I'm interesting in how one could animate patterns using ruby here. I recall certain "processing" animation scripts, just looping over a function using the array as an object and affecting the elements of the array creating interesting animations just due to the mathematics of the output.
Does anyone have any idea on how I could get started with something like that? I'm currently able to affect the LED's one at a time with my script, and I can string them together with `sleep x` after each command and manually build animations, but how could I make one run indefinitely with some sort of procedural animation?
---
I really didn't describe the bytecode array in its entirety, here are what each part does:
```
@sp.write ["\x01", led, "\x04\x00", "c", color]
^ ^ ^ ^ ^ ^
a b c d e f
a. start byte (not important, tells serial that it is the start of a command)
b. hex for LED address, ex. `\x07` is led 7
c. length of command (starting at "e")
d. bytes to be read (always 0 in our case)
e. the "fade to color" command
f. the color we want to fade to in rrggbb hex format.

Specifications-->
1. Chart RenderType = ImageMap
2. Chart ImageLocation = "/Images/Chart_#SEQ(1000,1)"
3. Number of app instances deployed on Windows Azure = 5
4. App contains a button which draws charts as per users parameters. When user clicks on this button, MVC action is called which provides necessary ViewData for drawing chart and returns a partial view which after getting rendered sends ImageMap and Image location to client.
When I try to draw charts from IE8 I always get the charts as per my parameters but when I simulataneously try to draw charts on FireFox sometimes I get wrong charts(wrong images).
Is it due to roundrobin used - #SEQ(1000,1) or due to mutiple instances of my cloud app ?

If I start the app, click on second tab the navbar displays correctly.
If I then immediately click on the first tab, and then back to the second tab again, the NavigationBar is clipped.

```

[navBar addSubview:urlTextField];
} else {
//XXX This does make the navBar display correctly
//but I don't really want the keyboard visible when returning from another tab
//[urlTextField becomeFirstResponder];
}
}
```
Note the final comment in the code above- If I force the keyboard to display, or if the user clicks in the UITextField, the NavBar is displayed correctly from therein.
I've tried a lot of things- checking the frames sizes of the View (View 2 in the images), the NavBar, but with no luck. Does any one have any idea what the problem might be? I'll be happy to give further detail.
Thanks.

## Update
I gave [Wallyk's answer](https://stackoverflow.com/questions/2353438/help-with-writing-a-mysql-query-involving-date-differences/2353479#2353479) a shot, changing it slightly in phpMyAdmin to SELECT just so I could see what was going on.
This is what I used
```
SELECT *
FROM properties
WHERE date_sub( `reserved_datetime` , INTERVAL 2 week ) >0
LIMIT 0 , 30
```
The only problem however, is that it has returned rows where the `reserved_datetime` is `2010-02-28 10:45:59`, definitely less than 2 weeks ago (from now).
I thought of checking MySQL's internal date. I have been using `date(DATE_ISO8601)` in my queries, because MySQL's `NOW()` wasn't exactly right (it just returned if interested `2010-02-28 20:09:19`).
Is there a way to specify the current date in that query? Any other suggestions?
Many thanks
## Another Update
Here is a screenshot from phpMyAdmin that may demonstrate anything better than my words can. Oh, and the reason it has returned 3 only is because all the others have blank values, i.e. `0000-00-00 00:00:00`
