2,355,931 | 1 | 2,355,963 | null | 8 | 8,223 | This is a similar question to this [one here](https://stackoverflow.com/questions/2350604/get-the-area-of-a-3d-surface).
Given a list of 3D coordinates that define the surface( `Point3D1`, `Point3D2`, `Point3D3`, and so on), how to calculate the of the surface?
In 2D the computation [is given by the following formula](http://en.wikipedia.org/wiki/Centroid#Centroid_of_polygon):
What about the 3D analogue?

2,356,472 | 1 | 2,360,143 | null | 4 | 795 | Some months ago there was a [nice question](https://stackoverflow.com/questions/1519462/maximum-bipartite-graph-1-n-matching) regarding a "" and there seems to be no poly-time algorithm.
I would like to add constraints to find a maximum matching for the 1:n matching problem with a polynomial algorithm. I would like to say: "For vertex A1 choose either {B1,B2,B5} or {B2,B3} if the vertices are not already taken from another A-vertex" i.e. I would not allow all possible combinations.
This could be expressed if we introduce helper vertices H for each choice and substitute edges with trees => we get a problem similar to the ordinary bipartite matching. Every vertex of A or B can have only one edge in the matching. The edges to or from vertices in H are either all in the matching or none of them is present in the matching. Imagine the following tri-partite graph:
Now define h_ij="tree rooted that contains H_ij" to express the matching easily:
- -
Would this problem then be solvable in polynomial time? If yes, is there a polytime solution for the weighted (w(h_ij)) variant? If no, could you argue or even proof it for a "simple-man" like me or suggest other constraints to solve the 1:n matching problem?
E.g. could the graph transformed to a general graph which then could be solved with the weighted matching for general graphs? Or could [branchings](http://cis.poly.edu/suel/papers/branch.pdf) or even [matching forests](http://books.google.com/books?id=mqGeSQ6dJycC&pg=PA1006&lpg=PA1006&dq=matching+forest&source=bl&ots=xOLSJ-dnPf&sig=kMwwFRAejcLwxOUHj0tRXs9NZ3k&hl=en&ei=QMaLS6SGHdLz_Aby5PXpBg&sa=X&oi=book_result&ct=result&resnum=10&ved=0CCUQ6AEwCQ#v=onepage&q=matching%20forest&f=false) help here?

2,386,866 | 1 | 2,386,929 | null | 672 | 613,210 | Here's my layout code;

</LinearLayout>
```
What this looks like is on the left and what I want it to look like is on the right.
The obvious answer is to set the TextView to fill_parent on height, but this causes no room to be left for the button or entry field.
Essentially the issue is that I want the submit button and the text entry to be a fixed height at the bottom and the text view to fill the rest of the space. Similarly, in the horizontal linear layout I want the submit button to wrap its content and for the text entry to fill the rest of the space.
If the first item in a linear layout is told to fill_parent it does exactly that, leaving no room for other items. How do I get an item which is first in a linear layout to fill all space apart from the minimum required by the rest of the items in the layout?

I have a Crystal Report that contains a field within a text object (to control line spacing) and has "can grow" selected. When I export the Crystal Report to a PDF there are instances when the text is cut off.
In this example the text is being cut off on the right side, but in some cases, when the text consists of many lines, the bottom part of the last line will be partially cut off.
I am using Crystal Reports that is bundled with Visual Studio 2008. The text area has "can grow" checked, the font is set to Helvetica LT Condensed, bold 14, and the line spacing is set to 0.75 times normal.
Anyone have any thoughts on how can I fix this?

2,390,400 | 1 | 2,412,879 | null | 8 | 4,233 | I'm developing an augmented reality application for Android that uses the phone's camera to recognise the arrangement of the coloured squares on each face of a Rubik's Cube.
One thing that I am unsure about is how exactly I would go about detecting and recognising the coloured squares on each face of the cube. If you look at a Rubik's Cube then you can see that each square is one of six possible colours with a thin black border. This lead me to think that it should be relativly simply to detect a square, possibly using an existing marker detection API.
My question is really, has anybody here had any experience with image recognition and Android? Ideally I'd like to be able to implement and existing API, but it would be an interesting project to do from scratch if somebody could point me in the right direction to get started.
Many thanks in advance.

[Why won't my .Net Windows service start automatically after a reboot?](https://stackoverflow.com/questions/998883/why-wont-my-net-windows-service-start-automatically-after-a-reboot)
However, the proposed solution was to have the service start after the services it depends on have started. However, when I go to the Dependencies tab for my service, I see:
Should I just use the workaround method of putting the thread to sleep, or is there a more proper way of getting this service to start correctly? Is this happening because .NET has not started before my service starts?
Thanks,
Tomek
EDIT: I have added a try-catch statement to catch the exception. Here is the code that I added to the OnStart() method of my service (which is where the exception is being thrown)
```
try
{
_watcher = new ManagementEventWatcher(query);
_watcher.EventArrived += new EventArrivedEventHandler(watcher_EventArrived);
_watcher.Start();
}
catch (Exception ex)
{
EventLog.WriteEntry("Could not create Sleep/Resume watcher" + ex.Message);
}
```
The service does start now but without the functionality that I have added. I am new to .NET, but I took the watcher code from a sample I found online, so I am pretty sure it is correct. The Event Log displays the same exception:
> Could not create Sleep/Resume watcher Call was canceled by the message filter. (Exception from HRESULT: 0x80010002 (RPC_E_CALL_CANCELED))

2,407,283 | 1 | 2,407,414 | null | 1 | 1,632 | I've been banging my ahead on this IE7 bug for the last few days and it's time to resort to the mind of the crowd.
I have the following HTML and CSS: [http://beerpla.net/for_www/ie7_test/test.html](http://beerpla.net/for_www/ie7_test/test.html)
The goal is to have a `<ul>`, with each `<li>` containing a small icon and some text. Multiline text would be aligned to itself and not wrap under the image.
I've tried using `float:left` on the image and a bunch of other things, and finally I thought the `position:absolute` would work for sure but in IE7 I consistently see the text pop off to the next line and get misaligned with the image:
This is what I expect it to look like:
I even tried to make the div `display:inline` which kind of worked but then started wrapping under the image for long lines, so it was no good. `zoom:1` also produced a similar effect.
I'm at a loss at the moment. This code works fine in all other browsers. IE7 is a special, very special child.
Any ideas?
Thank you.
If you have IE8, you can emulate IE7 by pressing F12 and then Alt-7.

In order to show the error I have created 2 gradient images. One has values in the 15 bit range (max of 32767) and one in the 16 bit range (max of 65535). Below are the two images
15 bit image
16 bit image
These two images were created in identical fashions and should look identical, but notice the line across the middle of the 16 bit image. At first I thought that this was an overflow problem however, it is weird that it's manifesting itself in the center of the gradient instead of at the end where the pixel values are higher. Also, if it was an overflow issue than I would suspect that the 15 bit image would have been affected as well.
Any help on this would be greatly appreciated.
I was just wondering why no one is answering, did I provide enough information? Is more info needed?
Below is the code I use to generate the AffineTransform. All of the referenced variables are calculated based off of user input (mouse movement) and should be correct (it's been tested by a lot of people including myself). Hopefully this can help with the error.

I still have no idea what's going on here. I'd really appreciate any help that can be provided. I've also attached an example of the bug happening in a real image that I encounter for more reference.
Here is the bug happening in an X-ray of the hand
Here is a zoomed up version focused on the area between the thumb and first finger.
Note again how the bug doesn't occur on the extremely white areas, but on the values in the middle of the dynamic range, just like in the gradient image.
I've discovered more information. I was adjusting some of the transforms and found that the bug does not occur if I just filter through an identity matrix. It also doesn't occur if I translate by an integer amount. It does occur if I translate by a non integer amount. It also occurs if I zoom by any amount other than 1 (integer or not). Hopefully this helps.
After more experimenting, the bug definitely manifests itself at the boundary pixels between half the max intensity (65535/2 = 32767.5). It also ONLY occurs at this value. I hope this might help diagnosis!!
At the request of AlBlue here is code that is completely independent of my application that can generate the bug. Note that in the original post I included an image gradient generated with the below code however I zoomed in on one of the gradients to better show the effect. You should see the effect four times on the 0.5 translated image and not on either of the other two images. Also note that this bug appears while scaling by any amount other than 1. Just replace AffineTransform.getTranslateInstance() with AffineTransform.getScaleInstance(0.9, 0.9) to see the bug also.
```
private static class MyJPanel extends JPanel {
BufferedImage displayImage = null;
public MyJPanel(double translateValue) {
super();
BufferedImage bi = new BufferedImage(1024, 1024, BufferedImage.TYPE_USHORT_GRAY);

}

}

Everything (surprisingly) works fine in IE, but firefox seems to totally clusterf*ck when this javascript is used. The first "slide" is okay, you drag, it says "sliding", you drop, it says "not sliding". On the second "slide" (or mousedown if you will), firefox suddenly thinks the div is an image or link and wants to drag it around.
Screenshot of the dragging:
Obviously the blue div half-positioned in the red div is the one being dragged. Windows does not capture the cursor when you take a screenshot, but it's a stop sign.
Is there someway to prevent this default behaviour?

I don't want to just set the height for container because the squares are not static so i want something that resizes automatically.

2,431,959 | 1 | 2,431,989 | null | 1 | 223 | I have a really simple Rails app. Basically an article with comments. I want the article page to show the article, comments underneath and then a textbox to write a comment and a submit button to submit it.
I got it all working except for one (big) problem. When the page loads.. example.com/article/1
a blank comment is submitted to the database.
I fixed that by including "validates_presence_of :body" in the Comment model. But that results in the following image when the page loads:
This is my code by the way:
```
def show
@place = Article.find(params[:id])
@comment = Article.find(params[:id]).comments.create(params[:comment])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @article }
end
end
```
and
```
<% form_for([@article, @comment]) do |f| %>
<p>
<%= f.label :commenter %><br />
<%= f.text_field :commenter %>
</p>
<p>
<%= f.label :body %><br />

2,433,555 | 1 | 2,433,823 | null | 0 | 4,250 | I'm curious if anyone knows of a way to easily get a double border effect in WPF similar to what you see in the selected items in Windows Explorer in Windows 7.
If you look closely, you'll notice that the selected item has a dark border, a lighter, inner-border, and then a gradient background.
Currently, I'm using two borders around an object any time I want to achieve this effect. Doing it that way is ugly syntactically and really muddies my view xaml. Being a web developer at heart I'd like to separate the xaml structure from the style as much as possible. So, I've started putting this into Styles and Content Templates in order to pull it out of my view xaml.
However, I'm curious if there may be a better way to go about this.
I played around for a while using a VisualBrush as a background to try to get the effect. However, I want to be able to apply the background to elements that can be any size and the way the VisualBrush stretched the visual to fit the element background didn't work the way I wanted it to. Essentially, I'd really just like it to stretch the visual the way the WPF layout system would do it.
Any ideas would be greatly appreciated.

You may notice the .less extension for the stylesheet. This is an ASP.NET MVC application and I'm making use of [DotLess](http://www.dotlesscss.com/). I have the HttpHandler hooked up for it in the web.config. Of course there's some additional info on the page, but (in theory) it shouldn't be causing this issue. I've run the CSS and the HTML through the W3C validators and both have come back as completely valid. I'm trying the arduous task of removing/re-adding elements until it displays, but any insight into what could cause this would help.
: it appears to be something related to the DotLess stylesheet. The resulting CSS is valid according to the W3C CSS validator.
: Digging further, and making use of IE's Developer Tools to control the styles, it appears that IE is reading a single statement twice even though it only occurs once in the output. Here's the output of the Less file:

Notice the `#newsfeed div .newFeatures` identifier near the end. I don't know what's causing that as it's only appearing once in the output stream. Here's an [image](https://i592.photobucket.com/albums/tt2/Agent_9191/IE_CSS_Error.png) of it too:
: It appears that even though it duplicates that particular selector, if I change the `font-size` to a whole number like `61%` instead of the current `60.95%` (that specific to defaultly match the existing desktop app as closely as possible) it works fine. I even moved the font-size (still as `60.95%`) to a more general selector (just the `.newFeature` one a few lines up) and it still causes the page to break. Still not sure why that is. I've added the full HTML to see what's going on.

2,434,602 | 1 | 14,101,451 | null | 567 | 496,118 | I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently.
I have a container `<div>` that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header `<div>`, and then an of items, all with CSS applied to them.
It looks a lot like this:
I want the to take up the remaining room in the container `<div>`, knowing that the header `<div>` is `18px` tall. I just don't know how to specify the list's height as "the result of `100%` minus `18px`".
I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. Does anyone have any advice in this situation?

2,439,102 | 1 | 2,439,109 | null | 2 | 79 | I'm working on a bigger project atm, but I made this simple example to show you what happens..
```
using System.Collections.Generic;
using System.Windows;
namespace txt
{
public partial class MainWindow
{
public MainWindow()
{
InitializeComponent();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
var obsLst = new List<Info> { new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" } };
var temp = new List<Info>();
for (var i = 1; i <= 3; i++)
{
temp.Add(obsLst[0]); //I add 3 of the same item from obsLst to temp
}
lst.DataContext = temp; //lst = ListBox
}
}
public class Info
{
public string name { get; set; }
}
}
```
The ListBox ItemsSource is set to {Binding}..
When I start the application I get 3 txt.Info objects displayed and if I click any of them, 2 or even all of them get selected aswell. From my understanding the problem relies in the fact that the listbox selector cannot differentiate between the items and therefor doesn't know which one I selected.
Here's a picture of what it looks like..
I only clicked on the second txt.Info item.
I found a solution where someone said that I have to specify the DisplayMemberPath, but I can't really do that in the other project because I have a datatemplate for the object.
Any ideas on how I could fix this would be great..
Thx in advance.
EDIT 1:
this works but it's not nice..
```
using System.Collections.Generic;
using System.Windows;
namespace txt
{
public partial class MainWindow
{
public MainWindow()
{
InitializeComponent();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
var obsLst = new List<Info> { new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" } };
var temp = new List<Container>();
for (var i = 1; i <= 3; i++)
{
var t = new Container();
t.obj = obsLst[0];
temp.Add(t);
}
lst.DataContext = temp;
}
}
public class Info
{
public string name { get; set; }
}
public class Container
{
public Info obj { get; set; }
}
}
```
In this case you need to set DisplayMemberPath="obj"
Assigning an ID to the object, doesn't work..
```
using System;
using System.Collections.Generic;
using System.Windows;
namespace txt
{
public partial class MainWindow
{
public MainWindow()
{
InitializeComponent();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
var rand = new Random();
var obsLst = new List<Info> { new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" }, new Info { name = "asd" } };
var temp = new List<Info>();
for (var i = 1; i <= 3; i++)
{
obsLst[0].id = rand.Next(10000);
temp.Add(obsLst[0]);
}
lst.DataContext = temp;
}
}
public class Info
{
public string name { get; set; }
public int id { get; set; }
}
}

2,441,053 | 1 | null | null | 6 | 1,296 | I have an iTunes style interface in my application: Source list (NSOutlineView) on the left that contains different libraries and playlists with an NSTableView on the right side of the interface displaying information for "Presentations". Similar to iTunes, I am showing the same type of information in the table view whether a library or playlist is selected (title, author, date created, etc).
I currently have an NSArrayController connected to my NSTableView and was setting the fetch predicate based on what was selected in the source list. This works fine when selecting a library because I can just set the fetch predicate to filter by the "type" field in my Core Data entity. When I try to adjust the fetch predicate for the playlist however, it doesn't look like there is any way to set the fetch predicate because I've got a table in between Playlists and Presentations to keep up with the order within the Playlist. According to the Apple docs, these type of predicates are not doable with Core Data (it basically doesn't multiple inner joins). Below is the relevant portion of my Data Model.
Is my data model setup incorrectly? Should I drop the NSArrayController and handle connecting the NSTableView up by hand? I'm trying to figure out if there is a simple fix, or really a design flaw.

2,456,336 | 1 | 2,456,465 | null | 4 | 2,734 | I want to have my own base TabItem class and use other classes that derive from it.
I define base class in MyNs namespace like this:
```
public class MyCustomTab : TabItem
{
static MyCustomTab()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomTab), new FrameworkPropertyMetadata(typeof(TabItem)));
}
}
```
And this is what I do for the class that inherits from it:
code-behind in MyNs namespace:
```
public partial class ActualTab : MyCustomTab
{
public ActualTab()
{
InitializeComponent();

```
XAML:
```

The error I get is "The tag 'MyCustomTab' does not exist in XML namespace '[http://schemas.microsoft.com/winfx/2006/xaml/presentation](http://schemas.microsoft.com/winfx/2006/xaml/presentation)'". If I use `TabItem` tag in XAML the error says that it's not possible to define to different base classes.

I've always loved the visual studio tabs and how they look. They're small and perfect. The normal .NET TabControl, well is plain and boring! I've seen these tabs being used in many applications. My question is:

2,458,245 | 1 | 2,458,649 | null | 3 | 8,561 | this is my core data model:
I'm trying to get all LanguageEntries from a database for a given category.categoryName and languageset.languageSetName e.g.
```
NSFetchRequest* fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"LanguageEntry" inManagedObjectContext:del.managedObjectContext];
[fetchRequest setEntity:entity];
NSString* predicateString = [NSString stringWithFormat:@"Category.categoryName = %@ AND LanguageSet.languageSetName = %@",
@"Food", @"English####Spanish"];
fetchRequest.predicate = [NSPredicate predicateWithFormat:predicateString];
NSError *error = nil;
NSArray* objects = [del.managedObjectContext executeFetchRequest:fetchRequest error:&error];
```
This always returns 0 objects. If I set the predicate string to match on one relationship (e.g. Category.categoryName = Food or languageSet.languageSetName = English####Spanish) it will return data.
This is baffling, can anyone shed some light?

2,459,402 | 1 | 2,459,541 | null | 50 | 29,972 | I am working with a hexagonal grid. I have chosen to use this coordinate system because it is quite elegant. 
[This question](https://stackoverflow.com/questions/2049196/generating-triangular-hexagonal-coordinates-xyz) talks about generating the coordinates themselves, and is quite useful. My issue now is in converting these coordinates to and from actual pixel coordinates. I am looking for a simple way to find the center of a hexagon with coordinates x,y,z. Assume (0,0) in pixel coordinates is at (0,0,0) in hex coords, and that each hexagon has an edge of length s. It seems to me like x,y, and z should each move my coordinate a certain distance along an axis, but they are interrelated in an odd way I can't quite wrap my head around it.
Bonus points if you can go the other direction and convert any (x,y) point in pixel coordinates to the hex that point belongs in.

The weak entity of LOAN uses a partial key of 'loan_dateLeant' and the primary keys from CUSTOMER and ITEM to form LOANs primary key.
However LOAN has a 'one to many' relationship with ITEM as a loan can consist of more than one item.
But surely this means that if more than one item is loaned, then the loan record will have two item_id values for part of its primary key?

done pretty well, and so we've been updating it as time allows.
However, one thing continues to bug me. I've never been able to get my
layered cards to anti-alias correctly.
Here's a sample:
Cards that are laid straight are very clean, but whenever they're
angled the black lines around the cards get jagged. I've tried this
depending on both lines implicit to the artwork and lines drawn
through drawRect:, and they both do the same thing. I've tried the
edgeAntiAliasingMask and it doesn't do a thing as far as I can tell.
I've tried masksToBounds for the sublayers set to NO and YES.
Right now my card is set up as a CALayer that has sub-CALayers for the
front and the back, plus for a few other things like a lightening mask
and a darkening mask. Here's some snippets of the code:
```
CArdLayer *theCardLayer = [CArdLayer layer];
theCardLayer.edgeAntialiasingMask = kCALayerLeftEdge | kCALayerRightEdge | kCALayerBottomEdge | kCALayerTopEdge;
theCardLayer.front = [CALayer layer];
theCardLayer.front.edgeAntialiasingMask = kCALayerLeftEdge | kCALayerRightEdge | kCALayerBottomEdge | kCALayerTopEdge;
theCardLayer.front.bounds = theCardLayer.bounds;
theCardLayer.front.masksToBounds = YES;
theCardLayer.front.contents = (id)[cardDrawing CGImage];
[theCardLayer addSublayer:theCardLayer.front];
```
Etc ...
Any ideas on how to make the cards actually anti-alias?

2,467,961 | 1 | 2,468,015 | null | 14 | 11,215 | When manipulating matrices it is often convenient to change their shape. For instance, to turn an N x M sized matrix into a vector of length N X M. In MATLAB a function exists:
> RESHAPE(X,M,N) returns the M-by-N matrix whose elements are taken columnwise from X. An error results if X does not have M*N elements.
In the case of converting between a matrix and vector I can use the Mathematica function which takes advantage of Mathematica's nested list representation for matrices. As a quick example, suppose I have a matrix X:
With [X] I can get the vector {1,2,3,...,16}. But what would be far more useful is something akin to applying Matlab's (X,2,8) which would result in the following Matrix:
This would allow creation of arbitrary matrices as long as the dimensions equal N*M. As far as I can tell, there isn't anything built in which makes me wonder if someone hasn't coded up a Reshape function of their own.
