5,268,135 | 1 | 5,268,196 | null | 2 | 2,902 | I have been trying to figure out a good strategy to perform a bitmap crop using Actionscript3.
For example: I have a picture of a car and I want to crop out the car from the image alone and feather the edges so that they do not look jagged.
I am a flash noob and have only been using it for a couple of weeks. I've tried a couple of options and here is the last one that I have come up with it: I place red dots on stage that are draggable so that you can outline the object you want to crop and the dots are the bounds for a gradientFill that is used as the bitmap's mask. (I am using a radial gradient ... so the results are far from what I want, since the car is not an oval).
(ignore the random yellow dotted oval)

1) How can I fade just the edges of this custom-shaped fill outlined by the red dots?
2) I want to save the image out to a file once it's cropped. What strategy would be better for doing this using a BitmapFill or a GradientFill as a Mask (If it's possible with both)?
3) I may be using this strategy to crop faces later on.. anyone know of any good face detection APIs for as3? (also edge detection APIs)
Thanks ahead everyone :)

5,268,247 | 1 | 5,268,450 | null | 0 | 934 | First of all, can I just say, I find laying out android UI's to be a frustrating experience? I used to think the XML layouts were simple and clean and awesome but every time I try to make anything with it I spend hours trying to do the simplest things!
In this particular instance I'm trying to make a simple horizontal bar that contains an image button of fixed size on the right and to the left of it I want an ImageView that takes up the rest of the available width. I see similar constructs all the time in the UI: the search box that appears at the top of the screen when searching, the text area and send button for composing text/googletalk messages, etc.
I've tried both a horizontal linear layout and a relative layout, and I can't get the button to look right in either one. My latest attempt has the following layout code:
It looks like this:
Using the hiearchyviewer indicates that both the imageview and the button have the same height (45px). And it shows the view dimensions and positions to be exactly what I'm looking for. Same height (differing widths of course since the ImageView is much wider). And they butt right up next to each other, centered in the Relative Layout. However the button as drawn on screen is obviously not taking up the full ImageButton view. I'm thinking it's something weird about the android system 9patch drawable used for the ImageButton background. But what do I know? I can't get it to look right no matter what I try.

5,268,467 | 1 | 5,302,659 | null | 2 | 2,019 | I am trying to make a NSScrollView with clipped corners, similar to the Twitter app:
I have a `NSScrollView` subclass which I added the following code:
```
- (void)drawRect:(NSRect)dirtyRect {
NSBezierPath *pcath = [NSBezierPath bezierPathWithRoundedRect:[self bounds] xRadius:kDefaultCornerRadius yRadius:kDefaultCornerRadius];
[path setClip];
[super drawRect:dirtyRect];
}
```
I expected the content of the `NSScrollView` to have rounded corners, but it is not respecting the clipped path. How can I do this?
I know how to make a custom `NSScroller`, I know how to make it transparent overlay. All I am asking is how to make the `NSSCrollView` clip its corners, including everything it contains. The `NSScrollView` is inside a `NSView` which has a background that could change, meaning a view overlay to fake the rounded corners is not an option.

5,268,595 | 1 | null | null | 0 | 745 | hours ago I post a question on organizing portrait and landscape mode in iPhone and now I think I know how to do it using willRotateToInterfaceOrientation:duration.
The first screen is 'Map View' with one button that leads to 'Setting View'. The Map View does not support rotate but for the Setting View I made separate view for portrait and landscape and they swap accordingly when rotated.
, , 
As you can see when Setting button pressed SettingView is added on the view stack as usual. So basically I use three view controllers; Setting, SettingLandscape and SettingPortrait.
I still found problem in rotating view in iPhone when I use navigationViewController. It used to working fine without rotation.- when I'm not using multiple view for rotation-.
This is root view controller.
```
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
```
}
```
-(IBAction) buttonPressed{
Setting *settingViewController = [[Setting alloc] initWithNibName:@"Setting" bundle:[NSBundle mainBundle]];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController: settingViewController];
[self.navigationController presentModalViewController:navController1 animated:YES];
[settingViewController release];
[navController1 release];
```
}
This view controller does nothing but swap views when rotate and shows appropriate view between portrait and landscape.
In Setting.m, I swap view as follow;
```
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if (toInterfaceOrientation==UIInterfaceOrientationLandscapeRight) {
NSLog(@"to Right");
SettingLandscape *setting_landscape = [[SettingLandscape alloc] initWithNibName:@"SettingLandscape" bundle:[NSBundle mainBundle]];
self.view = setting_landscape.view;
[setting_landscape release];
}
if (toInterfaceOrientation==UIInterfaceOrientationLandscapeLeft) {
NSLog(@"to Left");
SettingLandscape *setting_landscape = [[SettingLandscape alloc] initWithNibName:@"SettingLandscape" bundle:[NSBundle mainBundle]];
self.view = setting_landscape.view;
[setting_landscape release];
}
if (toInterfaceOrientation==UIInterfaceOrientationPortrait) {
NSLog(@"to Portrait");
SettingPortrait *settingportrait = [[SettingPortrait alloc] initWithNibName:@"SettingPortrait" bundle:[NSBundle mainBundle]];
self.view = settingportrait.view;
[settingportrait release];
}
if (toInterfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
NSLog(@"to PortraitUpsideDown");
SettingPortrait *settingportrait = [[SettingPortrait alloc] initWithNibName:@"SettingPortrait" bundle:[NSBundle mainBundle]];
self.view = settingportrait.view;
[settingportrait release];
}
```
}
In viewWillAppear, Setting view controller also has ;
```
self.title = @"Shell ";
self.navigationController.navigationBarHidden = NO;
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStylePlain target:self action:@selector(Done)] autorelease];
```
and Done is
```
- (void) Done{
[self dismissModalViewControllerAnimated:YES];
```
}
This view stacked on when the view is rotated. This view controller has it's navigation bar.
```
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.title = @"Setting Landscape";
```
}
```
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
```
}
in viewDidLoad;
```
- (void)viewDidLoad {
[super viewDidLoad];
NSLog(@"landscape:viewDidLoad");
//self.title = @"SettingLandscape";//not working!!
//self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Done1" style:UIBarButtonItemStylePlain target:self action:@selector(Done)] autorelease];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
stringflag4MapType = [[NSString alloc] initWithString:@"blah"];
stringflag4MapType = [defaults stringForKey:@"flag4MapType"];
if (![stringflag4MapType isEqualToString:@"Hybrid"] && ![stringflag4MapType isEqualToString:@"Standard"] && ![stringflag4MapType isEqualToString:@"Satellite"]) {
segmentedControl4MapType.selectedSegmentIndex = 0;
}else if ([self.stringflag4MapType isEqualToString:@"Standard"]) {
segmentedControl4MapType.selectedSegmentIndex = 0;
}else if ([self.stringflag4MapType isEqualToString:@"Satellite"]) {
segmentedControl4MapType.selectedSegmentIndex = 1;
}else if ([self.stringflag4MapType isEqualToString:@"Hybrid"]) {
segmentedControl4MapType.selectedSegmentIndex = 2;
}
```
and following call does not get invoked. strange. doesn't matter rotation works anyway.
```
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if (toInterfaceOrientation==UIInterfaceOrientationPortrait) {
NSLog(@"to Portrait");// does not print out.
SettingPortrait *settingportrait = [[SettingPortrait alloc] initWithNibName:@"SettingPortrait" bundle:[NSBundle mainBundle]];
self.view = settingportrait.view;
[settingportrait release];
}
if (toInterfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
NSLog(@"to PortraitUpsideDown");
SettingPortrait *settingportrait = [[SettingPortrait alloc] initWithNibName:@"SettingPortrait" bundle:[NSBundle mainBundle]];
self.view = settingportrait.view;
[settingportrait release];
}
```
}
ok now, as you can see from those snap shots there are two navigation bar and each has its bar button, Done and Item. The Done button came from Setting and the Item button from SettingPortrait or SettingLandscape. All button's selector is same, that leads back to map view. The button Done works fine, but the button Item crashes. I need a button on navigation bar after rotation that acts like back button . I guess once I did 'self.view = settingportrait.view;' the problem starts.

I'm having trouble calculating the "number" of the square that the cell belongs to (they start at 1, and increase from left-to-right, top-to-bottom), so that the numbers of the squares above are:
1|2

See how the window isn't selected? Is there any way around this without changing my whole app window level? Thanks!

In directory Public/Admin/ there is a file login.php. From login.php, I use the following function call...
to get the header for the login.php page.
The function it calls in the (Includes/functions.php file) is this
```
function include_layout_template($template=""){
include(SITE_ROOT.DS.'public'.DS.'layouts'.DS.$template);
}
```
which gets the admin_header.php file from the LAYOUT directory. I know the admin_header.php is loading properly into the login.php file using this function call because the html of the admin_header.php file is appearing when i load login.php. However, the admin_header.php file also has the link to the main.css file in the StyleSheets directory
```
<link href="../stylesheets/main.css" media="al" rel="stylesheet" type="text/css"/>

ReSharper, for some reason, tends to show me a correction that the return type of the method should be mapped to `System.Action<T>` or one of its variants. It seems that it won't recognize the non-generic version! VS complies and doesn't complain about this!
When I mouse over the red curly line, the tooltip shown says

void System.Action(T1, T2) ...

is there any API that allows you to build this up. Something like:

jqgrid("#grid").addPostDataFilters("AND");
jqgrid("#grid").addFilteritem("field", "cn", "value");
jqgrid("#grid").addFilteritem("field1", "eq", "value2");

to help generate to top postdata filter code ??

And classes such:
```
[Serializable]
public class Transaction : Entity
{
[DomainSignatureAttribute]
public virtual long TransactionId { get; protected internal set; }
public virtual long AccountId { get; set; }
protected internal virtual short TransactionTypeId { get; set; }
protected internal virtual short TransactionStatusId { get; set; }
public virtual DateTime DateCreated { get; set; }
public virtual DateTime DateEffective { get; set; }
public virtual Decimal Amount { get; set; }
public virtual IList<TransactionLink> ChildTransactions { get; set; }
public virtual IList<TransactionLink> ParentTransactions { get; set; }
public Transaction()
{
ChildTransactions = new List<TransactionLink>();
ParentTransactions = new List<TransactionLink>();
}
/// <summary>
/// Use this to add a payment to a charge to pay it off, or to add a refund on a payment to un-pay it
/// </summary>
/// <param name="inTransaction"></param>
/// <param name="inAmount"></param>
public virtual void AddChildTransaction(Transaction inTransaction, Decimal inAmount)
{
TransactionLink link = new TransactionLink()
{
TransactionParent = this,
TransactionChild = inTransaction,
Amount = inAmount
};
if (!ChildTransactions.Contains(link))
ChildTransactions.Add(link);
if (!inTransaction.ParentTransactions.Contains(link))
inTransaction.ParentTransactions.Add(link);
}
/// <summary>
/// You probably shouldnt be using this.
/// </summary>
/// <param name="inTransaction"></param>
/// <param name="inAmount"></param>
public virtual void AddParentTransaction(Transaction inTransaction, Decimal inAmount)
{
TransactionLink link = new TransactionLink()
{
TransactionChild = this,
TransactionParent = inTransaction,
Amount = inAmount
};
if (!inTransaction.ChildTransactions.Contains(link))
inTransaction.ChildTransactions.Add(link);
if (!ParentTransactions.Contains(link))
ParentTransactions.Add(link);
}
}
```
And
```
[Serializable]
public class TransactionLink : Entity
{
public virtual Int64 TransactionIdParent { get; protected internal set; }
public virtual Transaction TransactionParent { get; set; }
public virtual Int64 TransactionIdChild { get; set; }
public virtual Transaction TransactionChild { get; protected internal set; }
public virtual DateTime LastModifiedOn { get; set; }
public virtual Decimal Amount { get; set; }
#region Override comparison - as this is a composite key we need to custom roll our comparison operators
#endregion
}
```
Maps:
```
public TransactionMap()
{
Id(x => x.TransactionId);
Map(x => x.AccountId);
Map(x => x.TransactionTypeId);
Map(x => x.TransactionStatusId);
Map(x => x.DateCreated);
Map(x => x.DateEffective);
Map(x => x.Amount);
HasMany(x => x.ParentTransactions).Cascade.None().KeyColumn("TransactionIdParent").LazyLoad();
HasMany(x => x.ChildTransactions).Cascade.All().KeyColumn("TransactionIdChild").LazyLoad();
}
```
and
```
public TransactionLinkMap()
{
CompositeId()
.KeyProperty(x => x.TransactionIdParent, "TransactionIdParent")
.KeyProperty(x => x.TransactionIdChild, "TransactionIdChild");
References(x => x.TransactionParent).Column("TransactionIdParent").Cascade.SaveUpdate().LazyLoad();
References(x => x.TransactionChild).Column("TransactionIdChild").Cascade.All().LazyLoad();
Version(x => x.LastModifiedOn);
Map(x => x.Amount);
}
```

Is it possible to fix this behavior?

5,274,089 | 1 | 5,311,111 | null | 7 | 9,397 | I am trying to display an Android activity with:

```
In addition, the activity is styled with `@android:style/Theme.Dialog` and `android:windowNoTitle`.
I'm not sure I understand why this layout expands to fill the whole screen. None of the views have a layout height set to `fill_parent`; the parent layout isn't set to `fill_parent` either.
Does anyone know if what I want to do is possible, and if yes how to do it?

5,275,619 | 1 | 5,276,363 | null | 3 | 1,713 | I'm playing around with drawing my own custom controls using the uxTheme library in Windows, and I can't work out why my control doesn't look like the regular Windows control that (supposedly) uses the same theme I'm using:
The above image shows a standard Windows ComboBox (top) and my custom control drawn using the ComboBox theme (bottom). What I can't work out is why the border from my control is a different shape and colour to the standard control.
In my class constructor I open the theme data:
```
mComboTheme = OpenThemeData( hwnd, L"COMBOBOX" );
```
And then in the handler for WM_PAINT I'm just drawing two parts of the ComboBox components:
```
case WM_PAINT:
{
PAINTSTRUCT ps;
HDC hdc;
RECT client;
if( GetUpdateRect( hwnd, &ps.rcPaint, false ))
{
hdc = BeginPaint( hwnd, &ps );
GetClientRect( hwnd, &client );
if( IsThemeBackgroundPartiallyTransparent( mComboTheme, CP_BACKGROUND, CBXS_HOT ))
{
DrawThemeParentBackground( hwnd, hdc, &ps.rcPaint );
}
DrawThemeBackground( mComboTheme, hdc, CP_BACKGROUND, CBXS_HOT, &client, &ps.rcPaint );
client.left = client.right - 20;
DrawThemeBackground( mComboTheme, hdc, CP_DROPDOWNBUTTONRIGHT, CBXSR_HOT, &client, ps.rcPaint );
EndPaint( *this, &ps );
}
break;
}
```
Any suggestions as to why these two controls don't look the same would be greatly appreciated.
Thanks,

5,276,237 | 1 | 5,276,515 | null | 2 | 2,561 | I'm trying to replicate a dotplot of batches/cases/treatments with lines crossing the factors in ggplot. That is something like this plot from Douglas Bates' linear models course which shows 6 groups on the y axis with a continuous response on the x axis with the mean for each group joined by a line:
Using the sleepstudy dataset bundled with the lme4 package as an example, I have:
```
library(ggplot2)
p <- ggplot(sleepstudy, aes(x=Reaction, y=reorder(Subject, Reaction)))
p <- p + geom_point()
print(p)
```
Which gives the basic dotplot, with subjects on the y axis in order of increasing reaction time.
I then create a data frame with mean reaction times for each subject:
```
mean_rxn <- function(df) mean(df$Reaction, na.rm=T)
sleepsummary <- ddply(sleepstudy, .(Subject), mean_rxn)
```
I am able to plot points at the mean for each subject:
```
p.points <- p + geom_point(data=sleepsummary, aes(x=V1, y=reorder(Subject, V1), size=10))
print(p.points)
```
But I can't get lines to cross the factors. That is, changing from geom_point to geom_line displays nothing
```
# does nothing
p.line <- p + geom_line(data=sleepsummary, aes(x=V1, y=reorder(Subject, V1)))
print(p.line)
```
Anyone have any ideas? Ultimately, my goal is to plot some model results on top of the raw data in this fashion, so methods that calculate means "on the fly" in the plotting of the original data frame are less useful because I need to get my data points from a more complex model fit.
Thanks for any help!

5,276,538 | 1 | 5,293,306 | null | 2 | 1,066 | Check out the following pic. This happens when you expand a folder in Mac OS X from its shortcut on the dock. I'd like to do something very similar in SL. And in case it's difficult to understand - the dock is on the right, with the folder-speech-bubble expanding up & out to the left. The folder contents would be icons out of frame in the upper-left.
The best I've come up with is including a xaml Path that makes up the "leader" portion of the bubble and placing it directly over the border of a canvas. It looks like the following.
The Path, being a separate element, doesn't "integrate" well with the Grid and causes two issues. If you look closely you'll see that there is a slight transparency and the Grid's border is subtly bleeding through. Something else that will crop up, if I use a border thickness > 1, is the line-end caps between the Path border and the Grid border won't be connected, they'll simply overlap looking chunky and unpolished.
What I need is a solution that allows me to slide the leader up & down the speech bubble (depending upon its context) and adapts to the issues explained above. I'd be happy with ideas, examples, and down right full implementations.

5,276,701 | 1 | 5,299,244 | null | 7 | 3,130 | I want to implement a rather complex CurveEditor that has to support the usual requirements like:
- - - - -
I don't want to manipulate actual WPF curves but an existing model with key/value/tangents sets and sample the precise shape of the curve from our implementation.
I already gathered some experience on implementing custom UserControls and Templates. But I want to make sure, I don't miss any apparent solution. I planned to have this general XAML-tree:
- - - - - - - - - - - - - - - -
I know, this is quite a complex question and I am not asking for an actual implementation. I am interested in the following questions:
1. Can you recommend any tutorials or books that might help me (I already got Illustrated WPF, WPF Control Development Unleashed, and a couple of other)
2. Should minor elements like the Tangents be individual UserControls?
3. What container is best suited for hosting the individual "Curves", "EditPoints" and "Tangents". Right now, I use Canvas and Canvas.SetLeft/SetTop to position the children, but that feels "strange".
4. Should I use "Shapes" like Path or DrawingVisual-Classes to implement actual representation. Path is straight forward, but I am concerned about performance with hundreds of CurvePoints.
5. Should I use Transforms to rotate the tangents or is just fine to do some triangulation math in the code behind files?
6. Does the structure roughly make sense, or do you suggest a completely different approach?

This hasn't been an issue so far because I was always just passing IDs to my wcf service. But I'm trying to do something more complex now but I can't figure it out.
In my interface:
```
[OperationContract]

DataTableOutput GetDataTableOutput(string json);
```
My webservice:
```
public DataTableOutput GetDataTableOutput(string json)
{
DataTableOutput x = new DataTableOutput();
x.iTotalDisplayRecords = 9;
x.iTotalRecords = 50;
x.sColumns = "1";
x.sEcho = "1";
x.aaData = null;
return x;
}

```
var x = "1";
$.ajax({
type: "POST",
async: false,
url: "Services/Service1.svc/GetDataTableOutput",
contentType: "application/json; charset=utf-8",
data: x,
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
```
The above code WORKS perfectly. But when I change x to "t" or even to "{'test':'test'}" I get a Error 400 Bad Request error in Firebug.
Thanks,
John
EDIT:
Making some progress!
data: JSON.stringify("{'test':'test'}"),
Sends the string to my function!

```
var jsonAOData = JSON.stringify(aoData);
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",
data: "{'Input':" + jsonAOData + "}",
dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
```
EDIT3: I modified the code block I put in EDIT2 up above.
Swapping the " and ' did the trick!
```
$.ajax({
type: "POST",
async: false,
url: sSource,
contentType: "application/json; charset=utf-8",

dataType: "json",
success: function (msg) {
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
//alert(XMLHttpRequest.status);
//alert(XMLHttpRequest.responseText);
}
});
```
However, I have a new problem:
```
public DataTableOutput GetDataTableOutput(DataTableInputOverview Input)
{
```
The input here is completely null. The values I passed from jsonAOData didn't get assigned to the DataTableInputOverview Input variable. :(

I noticed that my site is sluggish after using it for several minutes. The animated GIFs play at lower framerate. They sometimes even stop animating. Hover effects on buttons have a noticeable lag. Is it possible that these hundred animated GIFs are still locking up the CPU even while they're hidden (`style="display: none"`)? At most, only a few GIFs are visible at any point in time.

5,278,829 | 1 | null | null | 7 | 27,459 | I'm having trouble getting some basic JNDI configuration going in Glassfish.
I have what I think ought to be a simple task: at run time, determine if a particular property is set to true or not. I think this is a good application of JNDI, but can't seem to get the path correct between the app server and my servlet code.
Here's how I have configured the property in Glassfish:
In my servlet code, I'm trying to look up the value with:
```
Boolean enabled = (Boolean) ctx.lookup("java:global/arizona/quartz_enabled");
```
In addition to this path, I've also tried the following without success:
- - -
My app is named "arizona", but deployed to the root context, if that matters.
I'm sure it's just a simple matter of figuring out the proper namespace to reach the property, but I feel like I'm just shooting in the dark trying to find it. Is there a simple way to browse the JNDI tree in Glassfish?

The layout looks like this:
```
<?xml version="1.0" encoding="utf-8"?>
<HorizontalScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/webRel"
android:layout_below="@+id/titlebar"

android:id="@+id/webZ"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</HorizontalScrollView>
```
And the results are as follows:
The webview isn't filling up the horizontalscrollview. The horizontalscrollview is filing the view, so I guess I could say the webview isn't filling the view even though I have both set to fill_parent. I would really, really like it if someone would help me figure out how to have the webview fill up the horizontalscrollview widthwise... because then I measure the height and use that measurement to paginate the text (which is then displayed in chunks widthwise which is why I chose horizontalscrollview.)
:D
(Alternatively, suggestions for a cleaner way to have smooth horizontal scrolling in a webview would also be helpful.)

writing it:

try {

Log.e("LONGITUDE EXTRACTED", exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE));

So, the problem is I am not encoding it in the properly defined format, which is something like you see here:
Can anyone explain what this format is? Obviously the first number is 22/1 = 22 degrees, but I can't figure out how to compute the decimal there.

5,281,261 | 1 | 5,284,527 | null | 42 | 65,589 | I'm working on procedurally generating patches of dirt using randomized fractals for a video game. I've already generated a height map using the midpoint displacement algorithm and saved it to a texture. I have some ideas for how to turn that into a texture of normals, but some feedback would be much appreciated.
My height texture is currently a 257 x 257 gray-scale image (height values are scaled for visibility purposes):
My thinking is that each pixel of the image represents a lattice coordinate in a 256 x 256 grid (hence, why there are 257 x 257 heights). That would mean that the normal at coordinate (i, j) is determined by the heights at (i, j), (i, j + 1), (i + 1, j), and (i + 1, j + 1) (call those A, B, C, and D, respectively).
So given the 3D coordinates of A, B, C, and D, would it make sense to:
1. split the four into two triangles: ABC and BCD
2. calculate the normals of those two faces via cross product
3. split into two triangles: ACD and ABD
4. calculate the normals of those two faces
5. average the four normals
...or is there a much easier method that I'm missing?

```
class RandomGaussian

private static Random random = new Random();
private static bool haveNextNextGaussian;
private static double nextNextGaussian;
public static double gaussianInRange(double from, double mean, double to)
{
if (!(from < mean && mean < to))

retval = from + (float)(interval1);
}
else
{
double interval2 = (NextGaussian() * (to - mean));
retval = mean + (float)(interval2);
}
while (retval < from || retval > to)
{
if (retval < from)
retval = (from - retval) + from;
if (retval > to)
retval = to - (retval - to);
}
return retval;
}
private static double NextGaussian()
{
if (haveNextNextGaussian)
{
haveNextNextGaussian = false;
return nextNextGaussian;
}
else
{
double v1, v2, s;
do
{
v1 = 2 * random.NextDouble() - 1;
v2 = 2 * random.NextDouble() - 1;
s = v1 * v1 + v2 * v2;
} while (s >= 1 || s == 0);
double multiplier = Math.Sqrt(-2 * Math.Log(s) / s);
nextNextGaussian = v2 * multiplier;
haveNextNextGaussian = true;
return v1 * multiplier;
}
}
}
```
Then to verify the results I plotted them with gaussianInRange(0, 0.5, 1) for n=100000000
As one can see the median is really at 0.5 but there isn't really a curve visible. So what I'm doing wrong?

Can any kind soul give this noob a step by step guide on how to get apps-for-android locally, compile, and run it on my test phone?
Edit:
Basically, in Eclipse with Subversive plugin, I create a new project by
File->New->Other->SVN->Project from SVN
then I use this URL, [http://apps-for-android.googlecode.com/svn](http://apps-for-android.googlecode.com/svn)
Then on this screen, I dont know what I should select, so I chosed: Checkout as a project with the name specified
Then the codes got downloaded to my workspace, with the SVN metadatas.
In my Eclipse, I can see that a new project has been created, but its not an android project.
I tried to use Android Tools to convert it to an Android project, but of course it did not work.
I also try to simply create a new project with the downloaded codes, and I was never able to compile it because Eclipse says there is an error with the project, but I cannot find the error at all.
I thought this is supposed to be very simple, but I have spent one afternoon on this, so thus looking if anyone has done this before to advise me...

5,283,070 | 1 | 5,284,375 | null | 0 | 7,625 | i have a website with jqgrid and I want to use both:
- -
I am using toolbarfilter setup using:
```
$("#grid").jqGrid('filterToolbar', { stringResult: true, searchOnEnter: true })
```
So, this way, users have 2 ways of filtering.
My issues are:
1. Toolbar Text does get removed after advanced filter (and is not factored into search request) If i have a toolbar search and hit enter. works great. If i then use click on the advance multi search and enter some criteria, it will "overwrite" the filter criteria BUT it leaves the text in the toolbar filter bar so when you see the results it confusing as the result set doesn't match with what you see in the toolbar filter text.
2. Going back and forth doesn't respect each other I set up initial advance multiple filter set, it works great. I then enter some text in the toolbar filter and hit enter, it sends ONLY that filter form the toolbar to the server (thus overwriting the existing filters set from the advance filter - which are now gone). If i go back to the advanced filter, it lists the old filter that i initially sent (not the latest filter that was generated from the toolbar filter). Is there anyway toolbarfilter and advancedfilter can work together and always build up a cumulative filter from both UI inputs, instead of overwriting each others in the request to the server.
So basically in both use cases above it seems like you are not supposed to use both forms of filtering together as they don't seem to play nice together.

5,283,845 | 1 | 5,286,849 | null | 2 | 3,714 | I'm having one, admittedly very minor issue with a contact form I've set up in WordPress using jQuery, jQuery form and PHP Mail to send a form-generated email.
To replace my current contact form which performs a pHp validation from within the contact form page and then sends using PHP Mail, I've designed the following simple html 5 form (which can be seen on this page: [http://edge.donaldjenkins.net/contact](http://edge.donaldjenkins.net/contact)):
```
<form id="contact" method="post" action="">
<fieldset>
<label for="name">Name</label>
<input type="text" name="name" placeholder="Your Name" title="Enter your name" class="required">
<label for="email">E-mail</label>
<input type="email" name="email" placeholder="[email protected]" title="Enter your e-mail address" class="required email">
<label for="phone">Phone</label>
<input type="tel" name="phone" placeholder="ex. (555) 555-5555">
<label for="website">Website</label>
<input type="url" name="url" placeholder="http://">
<label for="message">Question/Message</label>
<textarea name="message"></textarea>
<label for="checking" class="hidden">If you want to submit this form, do not enter anything in this field</label><input type="text" name="checking" class="hidden">
<input type="submit" name="submit" class="button" id="submit" value="Send Message" />
</fieldset>
```
I then use the jQuery validate [jquery.validate.js] and form [jquery.form.js] plugins to perform a client-end validation:
```
<script src="js/jquery.validate.js"></script>
<script src="js/jquery.form.js"></script>
<script>
$(function(){
$('#contact').validate({
submitHandler: function(form) {
$(form).ajaxSubmit({
url: 'send-message.php',
success: function() {
$('#contact').hide();
$('#instructions').hide();
$('#status').show();
$('#popular-posts').show();
$('#status').append("<p>Thanks! Your request has been sent. One will try to get back to you as soon as possible.</p>")
}
});
}
});
});
</script>
```
After the validation, the above script uses jQuery.form's [ajaxSubmit function](http://www.malsup.com/jquery/form/#options-object) to submit the date to a server PHP page, send-message.php (the reason being that javascript can't send email). I use this PHP file to carry out a second, server-side validation of the data (though this is probably redundant, since because the setup relies on javascript to pass the data on to the server, one can safely assume that no one will be able to use the form without javascript enabled). It also performs a honeypot captcha check on data in a hidden input field added in the form. The email is then sent:
```
<?php
//invoke wp_load in order to use WordPress wp_mail plugin function instead of mail for better authentification of the sent email
require_once("/path/to/wp-load.php");
//Check to see if the honeypot captcha field was filled in
if(trim($_POST['checking']) !== '') {
$captchaError = true;
$errors .= "\n Error: Captcha field filled in";
} else {
//Check to make sure that the name field is not empty
if(trim($_POST['name']) === '') {
$errors .= "\n Error: Name field empty";
$hasError = true;
} else {
$name = strip_tags($_POST['name']);
}
//Check to make sure sure that a valid email address is submitted
if(trim($_POST['email']) === '') {
$emailError = 'You forgot to enter your email address.';
$hasError = true;
} else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) {
$errors .= "\n Error: Message field empty";
$hasError = true;
} else {
$email = strip_tags($_POST['email']);
}
//Check to make sure comments were entered
if(trim($_POST['message']) === '') {
$errors .= "\n Error: Message field empty";
$hasError = true;
} else {
$phone = strip_tags($_POST['phone']);
$url = strip_tags($_POST['url']);
if(function_exists('stripslashes')) {
$message = stripslashes(trim($_POST['message']));
} else {
$message = strip_tags($_POST['message']);
}
}
//If there is no error, send the email
if(!isset($hasError)) {
// Send Message
$emailTo = '[email protected]';
$subject = 'Contact Form Submission from '.$name;
$body = "Name: $name \n\nEmail: $email \n\nPhone: $phone \n\nWebsite: $url \n\nMessage: $message";
$headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;
wp_mail($emailTo, $subject, $body, $headers);
$alert = 'Thanks! Your request has been sent. One will try to get back to you as soon as possible.';
} else {
$alert = $errors;
}
} ?>
```
The server keeps track of whether errors were found or whether the email was successfully sent in variable $alert.
After the pHp function completes, the script hides the form from the contact page and displays a previously hidden html element to which it appends an alert message.
The issue I can't solve is making javascript change the wording of that alert message to reflect whether the email was or not successfully sent, because I don't know how to pass the requisite pHp variable ($alert) containing a list of the error messages in the server PHP process to the script for insertion in the Contact Form page. Of course, again, this is a very theoretical concern, since for the reasons stated above, it's unlikely that an error-prone message would even have reached the PHP stage in the first place.
I've tried inserting the following code at the end of the PHP file, to no avail:
```
<script type="text/javascript">
alert = <?php echo $alert; ?>;
</script>
```
The latter attempt doesn't generate any errors in Firebug, but the variable value doesn't get passed on. Any ideas or thoughts welcome.

5,284,479 | 1 | null | null | 1 | 721 | I'm working in objective-c and I'm allocating a dynamic array of floats, but the size depends on the size of another array. So my allocations goes something like this:
```
float myFloats[[myArray count]];
```
All is working fine except when I do an analyze build in xcode. When using an element of the array a get a message like "The right operand is garbage value"
I've tried initializing going through all the elements and setting them to zero, but the analyze compiler does not take it into account.
Any one knows how to do it properly?
```

//Here I initialize the float array.
float clicksFromMiddle[[self.plannerViewArray count]];
NSRect actualPlannerFrame[[self.plannerViewArray count]];
PlannerView *plannerView;
for(int i = 0; i < [self.plannerViewArray count];i++){
plannerView = [self.plannerViewArray objectAtIndex:i];
actualPlannerFrame[i] = [plannerView frame];
//Below is where the values are set.
if (plannerView.isLeftPage) {

5,284,643 | 1 | 5,284,919 | null | 8 | 1,538 | I've been working on a simple frequency detection setup on the iphone. Analyzing in the frequency domain using FFT results has been somewhat unreliable in the presence of harmonics. I was hoping to use Cepstrum results to help decide what fundamental frequency is playing.
I am working with AudioQueues in the AudioToolbox framework, and do the Fourier transforms using the Accelerate framework.
My process has been exactly what is listed on Wikipedia's Cepstrum article for the Real Power Cepstrum, specifically: signal → FT → abs() → square → log → FT → abs() → square → power cepstrum.
The problem I have is that the Cepstrum results are extremely noisy. I have to drop the first and last 20 values as they are astronomical compared to the other values. Even after "cleaning" the data, there is still a huge amount of variation - far more than I would expect given the first graph. See the pictures below for the visualizations of the frequency domain and the quefrency domain.
[FFT](https://i.stack.imgur.com/jaKLu.png)
[Cepstrum](https://i.stack.imgur.com/Woteg.png)
When I see such a clear winner in the frequency domain as on that graph, I expect to see a similarly clear result in the quefrency domain. I played A440 and would expect bin 82 or so to have the highest magnitude. The third peak on the graph represents bin 79, which is close enough. As I said, the first 20 or so bins are so astronomical in magnitude as to be unusuable, and I had to delete them from the data set in order to see anything. Another odd quality of the cepstrum data is that the even bins seem to be much higher than the odd bins. Here are the frequency bins from 77-86:
```
77: 151150.0313
78: 22385.92773
79: 298753.1875
80: 56532.72656
81: 114177.4766
82: 31222.88281
83: 4620.785156
84: 13382.5332
85: 83.668259
86: 1205.023193
```
My question is how to clean up the frequency domain so that my Cepstrum domain results are not so wild. Alternately, help me better understand how to interpret these results if they are as one would expect in a Cepstrum analysis. I can post examples of the code I'm using, but it mostly uses vDSP calls and I don't know how helpful that would be.

5,285,161 | 1 | 5,285,231 | null | 1 | 11,541 | I am currently trying to develop a website where I need to have 2 CSS containers side by side at the same level. I.e. they both need to have top: 0px; However, whey they both have relative the first container is pushed down to where the second container content finishes.
How can I get these two containers to sit side by side both needing to be relative. I have been trying to figure it out for ages and google searches don't seem to provide with much help.
I am using HTML5 and CSS3 in order to build the website.
Thanks for any help you can offer.
Below is the HTML Code
```
<div id="feedContainer">
Latest Tech News<br /><
The quick brown<br/> fox jumped over the lazy<br /><br />dogs back
</div>
<div id="bodyIndex">
Hi I am a body<br />and i am a new line<br/>r />and i am a <strong>another new line</strong><br />I'm another<br /><br />woo!!<br /><br />
<font size="+24">I am a large font<br /><br />Please don't move<br />the feed container
</font>
</div>
```
Below is the CSS Code
```
#bodyIndex
{
position: relative;
margin-left: 120px;
padding-left: 15px;
padding-top: 5px;
width: 660px;
/*padding-bottom: 70px;*/
/*height: 100%;*/
/*top: 80px; */
/*background-color: #c8c8c8;*/
background-color: #fff6d1;
/*clear: both;*/
clear:none;
padding-bottom: 60px;
min-height: 100%;
height: auto;
}
#feedContainer
{
position:relative;
/* top: 0px;*/
top: 0px;
bottom: 0;
width: 180px;
padding-left: 5px;
left: 800px;
font-size: larger;
font-weight: bold;
color: black;
border-left:thin solid #e0e0e0;
clear: none;
}
```
In the image above where it says 'I am a body' and 'Latest Tech News' should be lined. The only way I can get them to line up is if I set one of them to absolute but I need both containers to be relative

5,285,306 | 1 | 5,285,478 | null | 11 | 1,069 | I am aware that by default Java does not have the so-called `eval` (what I pronounce as "evil") method. This sounds like a bad thing—knowing you do not have something which so many others do. But even worse seems being notified that you have it.
My question is: What is solid reasoning behind it? I mean, Google'ing this just returns a massive amount of old data and bogus reasons—even if there is an answer that I'm looking for, I can't filter it from people who are just throwing generic tag-words around.
I'm not interested in answers that are telling me how to get around that; I can do that myself:
### Using Bean Scripting Framework (BSF)
File `sample.py` (in `py` folder) contents:
```
def factorial(n):
return reduce(lambda x, y:x * y, range(1, n + 1))
```
And Java code:
```
ScriptEngine engine = new ScriptEngineManager().getEngineByName("jython");
engine.eval(new FileReader("py" + java.io.File.separator + "sample.py"));
System.out.println(engine.eval("factorial(932)"));
```
### Using designed bridges like JLink
This is equivalent to:
```
String expr = "N[Integrate[E^(2 y^5)/(2 x^3), {x, 4, 7}, {y, 2, 3}]]";
System.out.println(MM.Eval(expr));
//Output: 1.5187560850359461*^206 + 4.2210685420287355*^190*I

5,285,637 | 1 | 5,285,695 | null | 1 | 1,678 | I'm constructing a dynamic query to select dropped domain names from my database. At the moment there are a dozen rows but I'm going to get data soon which will have records of up to 500,000 rows.
The schema is just one table containing 4 columns:
```
CREATE TABLE `DroppedDomains` (
`domainID` int(11) NOT NULL AUTO_INCREMENT,
`DomainName` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
`DropDate` date DEFAULT NULL,
`TLD` varchar(5) COLLATE utf8_unicode_ci DEFAULT NULL,
PRIMARY KEY (`domainID`)
) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci
```
I did not create the schema, this is the live database schema. Here's sample data:
I've constructed probably the most complex type of query below. The criteria is as follows:
SELECT any number of domains which
>
1. Start with the word 'starts'
2. End with the word 'ends'
3. Contain the word 'containsThis' anywhere in the domain name
4. Contain the word 'ContainsThisToo' anywhere in the domain name
5. Include at least one digit
6. The domain name must be at least 49 characters. Multibytes need to count as one character( I used CHAR_LENGTH ).
7. The domain name must be at least under 65 characters.
8. The TLD must be 'org'
9. The DropDate needs to be later than 2009-11-01
Here's my query so far:
```
SELECT
*
FROM
DroppedDomains
WHERE
1=1
AND DomainName LIKE 'starts%ends'
AND DomainName LIKE '%containsThis%'
AND DomainName LIKE '%containsThisToo%'
AND DomainName LIKE '%-%'
AND DomainName REGEXP '[0-9]'
AND CHAR_LENGTH(DomainName) > 49
AND CHAR_LENGTH(DomainName) < 65
AND TLD = 'org'
AND DropDate > '2009-11-01'
```
Here are my questions
1. Would it extremely benefit the performance considering I'll have half a million rows, if I made the TLD column its own table and just make the TLD column a foreign key to that? There will only be 5 TLDs ( com, net, org, info, biz ). I realize there are more TLDs in the real world, but this application will only have 5. The user cannot specify their own TLD.
2. I know that REGEXP and 500,000 rows is probably a recipe for disaster. Is there anyway I can avoid the REGEXP?
3. Are there any other optimizations to the query I can do? Like merge LIKEs or use other functions such as maybe INSTR? And should I implement any specific sort of caching mechanism?
