I've been working on an image-emboss procedure with my class' special image ADT, but I can't seem to figure it out. I have included my recently edited code and the image procedures that I have been using for the problem. If you have a couple minutes to sit through the explanation, you might find this type of image editing interesting.
```
(define bound
(lambda (n)
(cond
[(<= n 0) 0]
[(>= n 255) 255]
[else n])))
```
Bound takes an integer and crops values outside the range 0 to 255, inclusive, to the endpoints.
```
(define boost
(lambda (x)
(bound (+ 127 x))))
```
Boost takes an integer, adds 127 to it, and then bounds the result. The number 127 is the focus of boost because we will use boost to boost colors and 127 is half the range of a color component.
```
(define image-emboss
(lambda (img)
(define emboss
(lambda (r c)
(let ([a (image-ref img r (add1 c))]
[b (image-ref img (add1 r) (add1 c))]
[c (image-ref img (sub1r) (add1 c))]
[d (image-ref img r (sub1 c))]
[e (image-ref img (sub1 r) (sub1 c))]
[f (image-ref img (add1 r) (sub1 c))])
(if (or (< r 0) (< c 0))
img
(make-image r c (boost (- (+ a b c) d e f)))))))
(emboss r c)))
```
"In an embossed image, the color of each pixel is computed from six of the pixels neighbors in the original image. Each color component of the embossed pixel is obtained by adding the corresponding components of the three pixels in the row directly above it and subtracting the components from the three pixels in the row directly below it, and then applying boost to the result."
I've tried to create image-emboss: it takes an image and returns an embossed version of the image. Pixels along the perimeter are unchanged. This proc is supposed to use make-image and image-ref.
Image-rows takes an image and returns the number of rows in the image.
```
(define image-rows
(lambda (img)
(cond
[(image? img 1 1) (vector-length (img))]
[else
(error 'image-rows (format "~a is not an image" img))])))
```
Image-cols takes an image and returns the number of columns in the image.
```
(define image-cols
(lambda (img)
(cond
[(image? img 1 1) (if (zero? (vector-length (img)))
0
(vector-length (vector-ref (img) 0)))]
[else
(error 'image-cols (format "~a is not an image" img))])))
```
Image-ref takes an image, row-index, and column-index, and returns the pixel.
```
(define image-ref
(lambda (img r c)
(if (not (image? img 0 0))
(error 'image-ref "first argument is not an image"))
(if (and (integer? r) (<= 0 r (- (image-rows img) 1)))
(if (and (integer? c) (<= 0 c (- (image-cols img) 1)))
(vector-ref (vector-ref (img) r) c)
(error 'image-ref (format "~a is an illegal index" c)))
(error 'image-ref (format "~a is an illegal index" r)))))
```
Make-image takes rows, cols, and a procedure.
```
(define make-image
(lambda (rows cols . args)
(let ([gen-proc
(cond
[(null? args) (lambda (i j rows cols) black)]
[(not (null? (cdr args)))
(error 'make-image "too many arguments")]
[(color? (car args)) (lambda (i j rows cols) (car args))]
[(procedure? (car args)) (car args)]
[else (error 'make-image (format "unknown fill: ~s"
(car args)))])])
(let ([img (make-vector rows)])
(let loop ([i 0])
(when (< i rows)
(vector-set! img i
(let ([row (make-vector cols)])
(let loop ([j 0])
(when (< j cols)
(vector-set! row j (gen-proc i j rows cols))
(loop (+ j 1))))
row))
(loop (+ i 1))))
(lambda () img)))))
```
The way I am testing this is by dloading an image and defining it in the repl, then drawing the image using a procedure created by my prof.
Anyways. I think my code is close to being correct, but I am really not sure how to correct it. If anyone has a hint/ better explanation that will help me figure this out, I'd really appreciate it. Thanks

I'm creating an HTML mail template for an app, and the template includes a 440px wide image.
When i look at it on my iphone, it goes beyond the width of the screen. I've seen plenty of times when iOS Mail shrinks the size of the email to fit everything in (for instance, emails from Apple).
Any ideas on what I might be doing wrong? The image CSS and it's container CSS is:
```
.photo {
width: 400px;
height: 460px;
padding: 20px;
background: #fff;
-moz-box-shadow: 0 0 10px rgba(0, 0, 0, .5);
-webkit-box-shadow: 0 0 10px rgba(0, 0, 0, 0.5);
box-shadow: 0 0 10px rgba(0, 0, 0, 0.5);
position: relative;
overflow: hidden;
}
.photo img.main-photo {
max-width: 400px;
}
.photo div.caption {
width: 400px;
position: absolute;
bottom: 20px;
font-family: 'Indie Flower';
height: 50px;
font-size: 20px;
}
```
and the actual HTML is
```
<div class="photo">
<img src="{{ photo.images.standard_resolution.url }}" class="main-photo" />
<div class="caption">
{{ photo.caption.text }}
</div>
</div>
```
Here is an example of how it looks. I dont want it to stretch beyond the screen

This is what I want... But how can I build this using CSS and DIV's?
I tried many tutorials, but it didn't came further than this:
```
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 13px;
background: #F0F0F0;
}
#wrapper {
padding: 1px;
margin: 0 auto;
}
#wrapper:after {
content: ".";
display: block;
clear: both;
height: 0;
overflow: hidden;
}
#left {
float: left;
width: 200px;
background: white;
padding: 5px;
}
#content {
margin-left: 215px;
background: white;
padding: 5px;
padding-left: 10px;
}
```

I have a ListView, and I have added a header (with getListView().addHeaderView) that simply contains a TextEdit widget.
Then when I tap the TextEdit to start writting, the keyboard appears and it messes up the list!
If I tap everywhere else to hide the keyboard, the list messes up again!
I don't know why is this happening. I thought it was something related with the onConfigurationChanged method, but after implementing it (and adding the corresponding attribute in the manifest file) the problem persists.
How could I fix it? Why is Android messing up my list?
My list uses a custom adapter, this is the getView method:
```
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v != null) {
return v;
}
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_row, null);
ListTask list_item = items.get(position);
if (list_item != null) {
TextView item_name = (TextView) v.findViewById(R.id.item_name);
item_name.setText(list_item.getTitle());
}
return v;
}
```
The problem is not the value of my items, but their order. They are displayed in a different order when the keyboard appears, but the values are correct.
Ok, I have changed my getView method with rekaszeru's suggestion and now it works as expected. But now I'm facing another problem:
Let's say the second textview is optional, and "Item 1" and "Item 3" have it, but "Item 2" does not, so it's initialized as a void String (length == 0).
The first time the list is displayed, it shows "Item1" and "Item 3" with their second textview, and "Item 2" without it. That's correct. But when the keyboard appears, the "Item 2" takes the second textview of another item and displays it!
This is the modified code I have right now:
```
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getContext().
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.list_row, null);
}
ListTask list_item = items.get(position);
TextView item_name = (TextView) convertView.findViewById(R.id.item_name);
TextView item_optional_text = (TextView) convertView.findViewById(R.id.item_optional_text);
item_name.setText(list_item.getTitle());
// if the item has defined the optional text, make some room and display it
if (item_optional_text.isNotEmpty()) {
LayoutParams layout_params = (LayoutParams) item_name.getLayoutParams();
layout_params.topMargin = 10;
layout_params.height = -2; // -2: wrap_content
item_name.setLayoutParams(layout_params);
item_optional_text.setText(list_item.getOptionalText());
}
return convertView;
}
```
The isNotEmpty() does this in the Item class:
```
public boolean isNotEmpty() {
return this.optional_text.length() > 0;
}
```
Maybe it's too complex to understand in a written question. If so, I can make a short video showing the problem and my source code. Thanks in advance for your help guys.

Hey fellas, while running through a debugger I am seeing the following appear the time it sets the variables (timestamp and checksum are set through this method one after the other, it works fine when no DataFeedManager exists, but upon returning to it again it crashes when it's time to set the checksum):
Here is the function of interest:
```
//sets specified attribute to the passed in value while ensuring that only one instance of the DataFeedManager exists
-(void)setItemInDFMWhilePreservingEntityUniquenessForItem:(attribute)attr withValue:(id)value {
SJLog(@"CoreDataSingleton.m setItemInDFMWhilePreservingEntityUniquenessForItem");
NSError *error;
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription
entityForName:@"DataFeedManager" inManagedObjectContext:[self managedObjectContext]];
[fetchRequest setEntity:entity];
NSUInteger numEntities = [[self managedObjectContext] countForFetchRequest:fetchRequest error:&error];
if (numEntities == NSNotFound) { // ERROR
//...
} else if (numEntities == 0) {
DataFeedManager *dfm = (DataFeedManager *)[NSEntityDescription insertNewObjectForEntityForName:@"DataFeedManager"
inManagedObjectContext:[self managedObjectContext]];
if (attr == checksumAttr) { //BLOCK OF INTEREST
NSString *tempVal = [[NSString alloc] initWithString:value];
[dfm setLastUpdateCheckSum:[NSString stringWithString:tempVal]];
} else if (attr == timeStampAttr) {
[dfm setTimeStamp:value];
}
} else { // more than zero entities
if (numEntities == 1) {
NSArray *fetchedObjects = [[self managedObjectContext] executeFetchRequest:fetchRequest error:&error];
if (attr == checksumAttr) { //BLOCK OF INTEREST
NSString *tempVal = [[NSString alloc] initWithString:value];
[[fetchedObjects objectAtIndex:0] setLastUpdateCheckSum:[NSString stringWithString:tempVal]]; //crashes at this line, after successfully going through the previous BLOCK OF INTEREST area
} else if (attr == timeStampAttr) {
[[fetchedObjects objectAtIndex:0] setTimeStamp:value];
}
} else { // ERROR: more than one entity
//...
}
} // else more than zero entities
[fetchRequest release];
}//setItemInDFMWhilePreservingEntityUniquenessForItem:withValue:
```
I have marked the areas of interest with `//BLOCK OF INTEREST` comments and have indicated upon which line the crash occurs (scroll right to see it!). Here is a readout of error from the console:

I believe it has something to do with copying the string adequately (can't set a string I don't own to the store). I have tried placing `[value copy]` as well as `&value`(saw this sort of thing work for someone else, so I thought I would give it a shot) to no avail. Shouldn't my current method adequately take ownership of the string? I still can't figure out what I am doing wrong. Any help appreciated. Thanks!

I've made a few custom controls to use in my projects, but i can't figure out how to set custom icons or descriptions like the pre-made visual studio controls have when you hover over them in the toolbox.
So far i've tried using this:
```
/// <summary>
/// Description of my Control
/// </summary>
```
And adding this attribute to my control class:
```
[System.ComponentModel.Description("Description of my Control")]
```
But i just cant figure it out, does anyone know?
Thanks.

OK so my brain is just probably not working tonight. What I'm trying to accomplish is a two column layout where one column scrolls and the other is fixed. The fixed column has a large background image in it that I would like to be able to scale to the size of the screen. Additionally the left (fixed) column's width would have to scale to accommodate the background image. The best way to really explain this is with a picture:
The highlighted area with the arrow in it will scroll and the other column with the picture and twitter status in it would remain fixed. My problem does not come into play with the fixed CSS positioning. My issue is with scaling my columns based on screen size so that the picture always remains in the proportion it's shown here both in it's own dimensions and those of the other column. That's what I'm stuck on. Any ideas? I really appreciate the help.

Hi I downloaded some PEAR files and they're in the bin folder of my MAMP directory. Inside the bin folder, they're in a bunch of subfolders (php 5.3/lib/php/pear etc) as you can see below
However, the files that are requiring PEAR are in htdocs, so they're not connecting at all. As I'm a newbie I'm cautious about taking all of those files from the php folder in bin and moving them into htdocs, yet it would also be a complicated file path to include them in every file from htdocs.
Has anyone used Pear. Is it supposed to be set up like this?
UPDATE -screenshot of Pear folder, and also screenshot of terminal pointing out suggested locations for pear

I have a Reason object:
```
public class Reason
{
public virtual long Id { get; set; }
public virtual string Name { get; set; }
public virtual Company Company {get;set;}
}
```
I am using entity framework 4 and Company is navigation property to Company.
I also use webservices in order to return data to the client.
I have web method that returns Reasons:
```
[WebMethod]
public Reason[] GetCallReasons()
{
IReasonRepository rep =
ObjectFactory.GetInstance<IReasonRepository>();
return rep.GetReasonsList().ToArray();
}
```
Because of the ef4 I get the following exception for executing the web method:
```
A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.Reason_24A0E4BBE02EE6BC2CF30BB56CFCB670C7D9D96D03D40AF4D174B89C9D3C5537'
```
The problem accurs because ef4 adds property that can't be serialized:
In order to solve this and eliminate the error, I can disable the navigation property by not making it virtual or by remove the navigation property. But I neet it and want to use the lazy loading feature.
I also can write spesific serializer for Reason but I have many many classes the I used in my web-services and write a serializer for all of them is a lot of work.
How can I solve this exception?..

I have a ListAdapter that contains a bunch of images that are being downloaded from the internet. When I scroll up and down there seems to be a performance hit and things get jerky. How can I resolve this?
```

I'm working on the details of a symbols pop up button, similar to what Xcode 3 at the top of its editor window.
My controller object is the delegate of the `NSMenu` that is shown when the `NSPopUpButton` is shown. I implement the two methods `numberOfItemsInMenu:` and `menu:updateItem:atIndex:shouldCancel:` to populate the menu right before it's about to be displayed.
However, the title and image of the selected `NSMenuItem` have to change each time the user changes the selection in the editor `NSTextView`, or makes changes to the text; just as is the case with Xcode.
The problem I'm having is when the user goes to click on the `NSPopUpButton` to display the `NSMenu`, the selected `NSMenuItem` and the item that should be selected do not match up, since the menu doesn't have the proper number of items yet.
I'm wondering if there is a way to control which `NSMenuItem` is initially highlighted and tracked when the user clicks to open the menu. As it stands, the first item it always highlighted and tracked or, if the user had previously selected a item, that item is highlighted and tracked.
I tried explaining as best I could, but here is a image illustrating my problem:
I want the highlighted item to be the same as the selected item when the user opens the menu. Any ideas?

From what I understand about A* heuristics and how the Bresenham algorithm works, this may not be be possible since only the current state and goal state are passed to the heuristic function. But maybe someone has a clever solution to this problem.
I am using A* to plan a path on a grid, and I would like a heuristic that would cause the best path to follow a Bresenham's line when there are free spaces between the current state and the goal or the next turn around an obstacle.
Here are some images to illustrate the problem.
If movements in the world acted like a checkers on a grid, this would be perfectly fine, but I'm eventually going to convert the A* path to motions on a continuously plane, so this does work very well.
Better, but still not perfect. Notice the straight line at the end. The diagonal could have just as easily remained a diagonal, which is what I want.
Bresenham lines are draw to the next turn or goal.
I found a good resource here, [http://theory.stanford.edu/~amitp/GameProgramming/Heuristics.html](http://theory.stanford.edu/~amitp/GameProgramming/Heuristics.html) that touches on what I am looking for, but only seems to work for drawing Bresenham lines from the start to the goal. What I want are Bresenham lines being draw to the next turn around an obstacle too.
Any ideas for a good approach to this problem?

I'm looking for a scala trait that I can mix in to a `scala.swing.Component` that will allow that component to be positioned and resized using mouse input.
Ideally it would add little boxes as "handles" to indicate to the user that the component can be resized:
I feel like this is a fairly common task, and there should be some traits out there that support it.

The image above shows a Nested model tree approach. i am searching for a query that will only display level number 1 with nodes FRUIT and MEAT when FRUIT or MEAT are called
I
I have formulate a combination of children and sibilings I think to pull of Beef when Red is called as below.
```
INSERT
$sqlinsert = "INSERT INTO categories
(categories_id, parent_id,name, parent)
VALUES('','','$name', '$parent')";
$enterquery = mysql_query($sqlinsert) or die(mysql_error());
$customer_id = mysql_insert_id();
```
I am looking to insert parent_id throug relating a new filled called parent that will be related to the existing field called "name" and then if parent field = to existing name field then take category_id from that name field and put it as the parent_id of the new INSERTED name.
for instance a user insert name "blue" and parent "food" then the name blue will take the categories id of food, and place it as the parent_id of blue...

I am trying to debug a Windows Azure WebRole which is an MVC3 project, but I want it to launch in any browser of my choice.
The Windows Azure is set as the Startup Project and launches the MVC3 project WebRole.
I am using Visual Studio Web Developer Express 2010.
I have previously stabbed in the dark by setting the following properties as in the image below but to no avail:
I then decided to set the project to not independently launch a page as above.
Is there a way to setup a default browser with the above scenario without changing my Windows default browser?

I'm generating an UIWebView into my viewDidLoad method, with a tiny size (let's say something like 50x70). And then I put it into a super UIView.
I'd like to make its content fit the webView frame. To do this, I wrote :
```
oneView = [[UIWebView alloc] initWithFrame:CGRectMake(x, y, W, H)];
oneView.backgroundColor = [UIColor whiteColor];
oneView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
oneView.scalesPageToFit = YES;
oneView.autoresizesSubviews = YES;
[self.view addSubview:oneView];
[oneView loadRequest:/*some request*/];
```
But doing this, the web page is not resized to the frame of the UIWebView.
It seems to be scaled to something else, smaller than the superview's frame, and wider than the webview's one.
If I set the webview frame size to the whole superview's size, it's ok.
How may I force the web content (real www content) to fit the frame of the "reduced" UIWebView ?

i am trying to make an application which would show which color my mouse is pointing to, i dont mean in my own application but anywhere in windows on any screen, kind of like a tag beside my mouse pointer which shows the exact color.
I am a Java developer but i dont think this could be done in java i am thinking maybe i need some sort of script but i have no idea any help would be really appriciated

I think this is a very basic question, but I am struggling with this one.
I have a screenshot (an UIImage) which I put into an UIView (called screenShotView in my sample below). I want to get rid of this screenShotView by gradually revealing what is behind this screenShotView. Right now my screenShotView SQUEEZES to the left, but I would like its FRAME to become less and less until the screenShotView is no longer seen (without Squeezing).
This is my code. If I did the same transformation with an UITextView (instead of an UIImage) it would work exactly how I would like it to behave (without transformation).
Perhaps I don't get the concept of framing UIImages?
```
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:10];
[screenShotView setFrame:CGRectMake(0, 0, 0, 480)];
[UIView commitAnimations];
```
---
And this is how it looks like in the middle of the animation:
And this is how I would like it to look like in the middle of the animation:
---
This is the code updated to Codo's suggestions (see below), with the result that I have no animation anymore. The blue screen simply pops up once the button is pressed. I guess that I am doing something wrong with adding the subviews -- the problem appears to be that no subviews are added and can therefore not disappear:
```
-(IBAction)showNextText
{
screenShotView = [[UIImageView alloc] initWithImage:[self screenshot]];
[screenShotView setFrame:CGRectMake(0, 0, 320, 480)];
[screenShotScrollView setFrame:CGRectMake(0, 0, 320, 480)];
[self.view addSubview:screenShotScrollView];
[screenShotScrollView addSubview:screenShotView];
screenShotScrollView.scrollEnabled = NO;
[self setUpNextText];
[self removeOldText];
}
-(void)setUpNextText
{
NSString* secondText = @"This is the second text shown if the user clicks next.";
textView.text = secondText;
textView.textColor = [UIColor redColor];
textView.backgroundColor = [UIColor blueColor];
}
-(IBAction)removeOldText{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:5];
[screenShotScrollView setFrame:CGRectMake(0,0,320,480)];
[UIView commitAnimations];
}
```

I'm working on a calendar/planner application and I need some advice.
I'm working on the following part of my application:
It shows the days of the month from 1 till the end of the month, 28/29, 30 or 31. I achieved this.. ([here](http://www.obscura-design.be/planner)) but my code is extremely ugly and I'm sure there must be another way to do this.
I'm working in CodeIgniter. My controller contains the following function to populate the list with the days of the month:
```
public function init_days()
{
// post values? in case of previous/next months (ajax)
if($this->input->post('post_month') && $this->input->post('post_year'))
{
$month = $this->input->post('post_month');
$year = $this->input->post('post_year');
$data = $this->planner_model->calendar_data($month, $year);
}
else
{
$data = $this->planner_model->calendar_data();
}
// init empty calendar
$data['calendar'] = '';
// easy var names
$current_month = $data['current_month'];
$current_year = $data['current_year'];
// echo list into $data['calendar']
for($i = 1; $i <= $data['days_in_month']; $i++)
{
if($current_month == date('n') && $current_year == date('Y'))
{
if($i < $data['current_day_of_month'])
{
$data['calendar'] .= "<li class='prev_month' value='$i'>$i</li>";
}
if($i == $data['current_day_of_month'])
{
$data['calendar'] .= "<li class='today' value='$i'>$i</li>";
}
if($i > $data['current_day_of_month'])
{
$data['calendar'] .= "<li class='next_month' value='$i'>$i</li>";
}
}
if( ($current_month > date('n') && $current_year == date('Y')) || ($current_year > date('Y')) )
{
$data['calendar'] .= "<li class='next_month' value='$i'>$i</li>";
}
if( ($current_month < date('n') && $current_year == date('Y')) || ($current_year < date('Y')) )
{
$data['calendar'] .= "<li class='prev_month' value='$i'>$i</li>";
}
}
$data['month_name'] = ucfirst($this->get_month_name($current_month));
header('Content-type: application/json');
echo json_encode($data);
}
```
My model returns the $data array that gets called by the controller (in the else clause, first part):
```
public function calendar_data($month = '', $year = '')
{
if( ! empty($month) && ! empty($year))
{
$data['current_year'] = $year;
$data['current_month'] = $month;
$data['current_day_of_month'] = date('j');
$data['current_day_of_week'] = date('w');
$data['days_in_month'] = cal_days_in_month(CAL_GREGORIAN, $month, $year);
}
else
{
$data['current_year'] = date('Y');
$data['current_month'] = date('n');
$data['current_day_of_month'] = date('j');
$data['current_day_of_week'] = date('w');
$data['days_in_month'] = cal_days_in_month(CAL_GREGORIAN, $data['current_month'], $data['current_year']);
}
return $data;
}
```
I then output this in my view with an AJAX call on $(document).ready.
`$("#day_list").html(data['calendar']).fadeIn();`
I'm not happy with the code. It's a mess, and I'm fairly sure I'm breaking MVC here; aren't I? Could someone perhaps give some advice or insights on how to do this in a 'better' way? Thanks a lot.
The full source is [here](https://github.com/cabaret/Studieplanner) in case anyone would be kind enough to look through it and tell me if there's other stuff I'm doing wrong.

If I remove the 2 red lines, then it lines up the way I want it to:
How could I make it line up like this and have the two red lines at the same time?

Sorry if it is wrong section to post this. I want use JW player as an audio player. So I want to take it out the area above control bar which display thumbnails because I only want control bar to display. If that's only one song, i can just change the height of the JW player but now what I want is with playlist. So If i change the height of the JW player, the bottom playlist is screwed up. I attached the image to make it clear.

I am looking to plot something like the whispering gallery modes -- a 2D cylindrically symmetric plot in polar coordinates. Something like this:
I found the following code snippet in Trott's symbolics guidebook. Tried running it on a very small data set; it ate 4 GB of memory and hosed my kernel:
```
(* add points to get smooth curves *)
addPoints[lp_][points_, \[Delta]\[CurlyEpsilon]_] :=
Module[{n, l}, Join @@ (Function[pair,
If[(* additional points needed? *)
(l = Sqrt[#. #]&[Subtract @@ pair]) < \[Delta]\[CurlyEpsilon], pair,
n = Floor[l/\[Delta]\[CurlyEpsilon]] + 1;
Table[# + i/n (#2 - #1), {i, 0, n - 1}]& @@ pair]] /@
Partition[If[lp === Polygon,
Append[#, First[#]], #]&[points], 2, 1])]
(* Make the plot circular *)
With[{\[Delta]\[CurlyEpsilon] = 0.1, R = 10},
Show[{gr /. (lp : (Polygon | Line))[l_] :>
lp[{#2 Cos[#1], #2 Sin[#1]} & @@@(* add points *)
addPoints[lp][l, \[Delta]\[CurlyEpsilon]]],
Graphics[{Thickness[0.01], GrayLevel[0], Circle[{0, 0}, R]}]},
DisplayFunction -> $DisplayFunction, Frame -> False]]
```
Here, `gr` is a rectangular 2D ListContourPlot, generated using something like this (for example):
```
data = With[{eth = 2, er = 2, wc = 1, m = 4},
Table[Re[
BesselJ[(Sqrt[eth] m)/Sqrt[er], Sqrt[eth] r wc] Exp[
I m phi]], {r, 0, 10, .2}, {phi, 0, 2 Pi, 0.1}]];
gr = ListContourPlot[data, Contours -> 50, ContourLines -> False,
DataRange -> {{0, 2 Pi}, {0, 10}}, DisplayFunction -> Identity,
ContourStyle -> {Thickness[0.002]}, PlotRange -> All,
ColorFunctionScaling -> False]
```
Is there a straightforward way to do cylindrical plots like this?.. I find it hard to believe that I would have to turn to Matlab for my curvilinear coordinate needs :)

This is similar to the "answered" question
[JQuery AJAX request behaving synchronous for unknown reason](https://stackoverflow.com/questions/5383247/jquery-ajax-request-behaving-synchronous-for-unknown-reason)
I believe that the actual issue with parallel execution observed by MGM has been overlooked and actually there is a problem with $.get/$.ajax executed in parallel.
Look at the snippet below:
```
$(function() {
$(".dd").each(function() {
var obj = $(this);
$.get("test.txt", function(data) {
obj.html(data);
});
});
});
```
It loads a file (asynchronously I would expect) and displays it (synchronously of course).
However, the code executes differently during the first page load and on page refresh. I am monitoring the requests to the server using firebug Net panel in Firefox 4.0 on Windows. On the first page load (or when refreshed using Ctrl-F5) I can see on the Net panel that multiple requests to the "test.txt" start at the same time and the Net acivity mostly overlapps.
This part works as expected. The result may be processed in the browser one by one, but the requests to the server are performed in parallel.
It is completly different story when user presses F5 to refresh the page. Suddenly parallelism is gone. And same web page loads "test.txt" one by one.
It becomes even more clear if I replace data display (obj.html(data);) with a simple alert: alert(data); On initial page load I get multiple alert messages on the screen at the same time. Subsequent refreshes (F5) clearly demonstrate that while one alert message is on screen no other downloads are performed (I can remove the file to see next "$.get" to fail).
So in fact the $.get does not perform async. calls to the server.
Any ideas on why this happening?
P.S. Sorry system does not allow me to post images use provided URL to see the screenshots.

I'm trying to code the appearance of an UILabel, but I can't get another font applied. The funny (or rather annoying) thing is that if I add a second UILabel, the font WILL BE APPLIED for the second label, BUT NOT the first. I'm slightly going crazy on this... especially the font size won't change if I try to.
My code (found in my ViewDidLoad):
```
NSString* dateWeekDay = @"MON";
CGRect dateWeekDayFrame = CGRectMake(183, 12, 34, 21);
viewNoteDateWeekDay = [[UILabel alloc] initWithFrame:dateWeekDayFrame];
viewNoteDateWeekDay.text = dateWeekDay;
viewNoteDateWeekDay.textColor = [UIColor blackColor];
viewNoteTitle.font = [UIFont fontWithName:@"Helvetica Neue" size:70.0f]; // I know this size is crazy, but it's just to show that it has no effect whatsoever...
viewNoteDateWeekDay.transform = CGAffineTransformMakeRotation( ( -90 * M_PI ) / 180 );
viewNoteDateWeekDay.backgroundColor = [UIColor clearColor];
NSString* dateDay = @"01";
CGRect dateDayFrame = CGRectMake(209, 3, 47, 50);
viewNoteDateDay = [[UILabel alloc] initWithFrame:dateDayFrame];
viewNoteDateDay.text = dateDay;
viewNoteDateDay.textColor = [UIColor blackColor];
viewNoteDateDay.font = [UIFont fontWithName:@"Helvetica Neue" size:33.0f];
viewNoteDateDay.backgroundColor = [UIColor clearColor];
NSString* dateMonth = @"SEPTEMBER";
CGRect dateMonthFrame = CGRectMake(249, 6, 93, 31);
viewNoteDateMonth = [[UILabel alloc] initWithFrame:dateMonthFrame];
viewNoteDateMonth.text = dateMonth;
viewNoteDateMonth.textColor = [UIColor blackColor];
viewNoteDateMonth.font = [UIFont fontWithName:@"Helvetica Neue" size:12.0f];
viewNoteDateMonth.backgroundColor = [UIColor clearColor];
```

Consider this HTML:
```
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css">
div {
position: relative;
width: 200px;
height: 200px;
background: #ff0;
}
span {
position: absolute;
width: 200px;
height: 200px;
background: #f00;
top: 100px;
left: 100px;
}
</style>
</head>
<body>
<div><span></span></div>
</body>
</html>
```
Output:
Now let's add some jQuery code that sets the opacity of the containing div to any level:
```
$('div').css({ opacity: '1' });
```
The output is now this:
How can I avoid this? [Here's a test page](http://files.mattalexander.me/ie7.html).
EDIT: It happens in IE6 as well.

When I use jQuery to set an element's opacity in IE6 or IE7, it seems to aquire "overflow: hidden". Why?

I hope I'm not repeating - it doesn't seem like there are any questions that have the same specifications as mine.
I'm looking for a way to "crop" a div with jQuery. The div is going to start with a width of zero, and then get animated to its full length. The tricky part is I want any text that overflows on the side to be hidden, rather than just pushed down to fill the space.
It doesn't seem like the regular "overflow: hidden" will work because I could have many lines of text, and I want each line to be "cropped", so the characters for the individual line are hidden instead of being bumped down to the next line. 
I hope this is clear. Any suggestions?

For a class project I'm working on "Pissed Off Pigs" (I think you get the idea, the pigs get revenge, don't worry, I'm not going to release it!) and I want to create circles with a fill from a bitmap (circles because the collision math is easier). Here is how they look now.
Of course, the white is the problem. Below is my "pigs" class. Any ideas? I've tried gif's, pngs, 8-bit pngs, etc and it seems to make no difference. The image itself is 20px square and the radius of the circle is 10px (so a 20px diameter). Here is the image I'm using: 
And I know I should probably load the image outside the class and just pass the BitmapData when I make a new pig so I don't have to load the image every time I create a new pig but for now it works! (Sorta).
Is the matrix translate the problem?
Oh, and I have checked bmpImage.transparent and it returns true (even when I don't specify true in the constructor).
`
package {
import flash.display.;
import flash.events.;
import flash.display.BitmapDataChannel;
```
public class pig extends Sprite {
public var radius:uint;
public var velocity:Vec2;
public var tt:Sprite;
public var pigLoader:Loader;
public var bmpImage:BitmapData;
public var framesAlive:uint;
public function pig(xx:uint, yy:uint, radius:uint, vx:Number, vy:Number, sprite:String){
this.x = xx;
this.y = yy;
this.radius = radius;
this.velocity = new Vec2(vx, vy);
pigLoader = new Loader();
pigLoader.load(new URLRequest(sprite));
pigLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, picLoaded);
}
private function picLoaded(event:Event):void {
bmpImage = new BitmapData(pigLoader.width, pigLoader.height, true);
bmpImage.draw(pigLoader);
tt = new Sprite();
var matrix:Matrix;
matrix = new Matrix();
matrix.translate( -10, -10);
tt.graphics.beginBitmapFill(bmpImage, matrix, false, false);
tt.graphics.drawCircle(0, 0, this.radius)
tt.graphics.endFill();
this.addChild(tt);
}
}
```

I have this ListView:
I'm using a custom adapter.
As you see, each row is made of a checkbox, a big TextView, and a little TextView.
All items have defined the little TextView, even the "Item 2" but it's a void string.
The problem comes when I tap the EditText placed in the header of the list:
The keyboard appears, and the rows are recycled, so the getView method of my adapter is called. In that method I have an if clause where I check if the length of the "optional" text (the little TextView) is greater than 0. In that case I make some room (the space that you can see in the screenshot) and I display it.
The problem is that "Item 2" has the "optional" text initialized but it's void (0-sized). I don't understand why the if clause is executed. But more strangely... the else is also executed! In the else I just show a void string in the little TextView.
Why is this happening? The app is really simple. This is my getView method:
```
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.list_row, null);
}
ListItem list_item = items.get(position);
TextView item_title = (TextView) convertView.findViewById(R.id.item_title);
TextView item_optional = (TextView) convertView.findViewById(R.id.item_optional);
item_title.setText(list_item.getTitle());
// If the task has an optional text, make some room and display it
if (list_item.hasOptional()) {
// This portion of code will be executed when you tap the EditText and the keyboard appears, putting the item up in the row
LayoutParams layout_params = (LayoutParams) item_title.getLayoutParams();
layout_params.topMargin = 10;
layout_params.height = -2; // -2: wrap_content
item_title.setLayoutParams(layout_params);
item_optional.setText(list_item.getOptional());
item_optional.setVisibility(0);
} else {
// This portion of code will ALSO be executed when you tap the EditText... why? this should not happen!
item_optional.setText("");
}
return convertView;
}
```

I have an html table that is displaying customer orders. One of these columns is a sub total which needs to add all rows for sub total in the order details table for that specific order. Is there a way to do this within my anonymous type?
Here's some images of what I'm talking about:
And the code i'm using minus the total amount addition:
```
var q = db.Orders.Where(x => x.siteUserID == 41)
.OrderByDescending(x => x.orderID)
.Select(x => new
{
dateCreated = x.dateCreated,
orderID = x.orderID,
count = x.OrderDetails.Count()
});
```
Currently I've created a class with identical properties of my LINQ query, and am adding the results to a `List` and within the list calling a function that adds up the sub total.
If it could be done within my original query it would be much cleaner.

I understand from reading [Arik Poznanski's blog](http://blogs.microsoft.co.il/blogs/arik/archive/2009/09/03/windows-ribbon-for-winforms-part-1-introduction.aspx) that the [Windows Ribbon UI Framework](http://msdn.microsoft.com/en-us/library/dd316910%28VS.85%29.aspx) is a COM object in Windows 7, and the [WindowsRibbon wrapper](http://windowsribbon.codeplex.com) is just a .NET veneer around that, to allow the Ribbon UI to be used in Windows Forms applications.
I've been successful in implementing a Hello World Windows Form app that employs this wrapper:
It is running on my development machine, which is Windows7.
---
Questions:
- Will this "hello, world" application run on Vista? XP? Do I need to download something onto those machines in order to make that happen? - Is there a way to specify the Windows Ribbon UI components as a pre-requisite, in an MSI installer?
Thanks
---
Browsing around I found [the documentation for UIRibbon.dll](http://msdn.microsoft.com/en-us/library/dd742706%28v=vs.85%29.aspx), which is the DLL on Windows7 that delivers the Ribbon UI. It lists these as minimum supported clients:
> Windows 7, Windows Vista with SP2 and Platform Update for Windows Vista
how would I check for that in an MSI ?

Can I use the Windows Ribbon UI on Windows XP? how?

I have a simple Rectangle struct with x, y, width, and height, which I thought would be easy to work with vectors but it turned out to be pretty messy.
This is what I have in main:
```
vector<CvRect> v;
v.push_back(cvRect(50,0,50, 50));
v.push_back(cvRect(150, 0, 50,50));
v.push_back(cvRect(100, 0, 50,50));
sort(v.begin(), v.end(), rectangleCmpByPosition);
```
I have this declared in my header
```
static int rectangleCmpByPosition(const CvRect &a, const CvRect &b);
```
with this as definition:
```
static int rectangleCmpByPosition(const CvRect& a, const CvRect &b){
if (a.y != b.y){
return a.y - b.y;
}else{
return a.x - b.x;
}
}
```
And visual studio throws this error message at me.
I spent the whole afternoon googling to see what I did wrong but I can't find the cause. Please help.

I have a development server and a production server. All developers push updates to the development server and the development server pushes updates to the production server.
Is there a Post-Receive hook for doing this? Assume that the development server and production server names are `dev1` and `prod1`.
If possible, is there a post-receive hook that checks for the tag `stable` before pushing to prod1?

A would like to plot geom_tile() without displaying the surrounding grey frame. Example:
```
library(ggplot2)
p <- ggplot(melt(volcano), aes(x = X1, y = X2, z = value,fill = value)) + geom_tile()
print(p)
```
Produces the figure below, which would look better had not the theme background framed the heatmap proper. I imaging the padding is the same 4% as in base graphics. It's good to have it most of the time, but not always.
I assume the same solution to this problem could be applied to other geoms as well.

I have a simple database with two tables: `Photo` and `Tag`. There is a one-to-many (a photo can have many tags) relationship between the two tables. Here is a diagram:
Now I have made a `Photo` class and set it up for LINQ-to-SQL using attributes. The code for that class is below:
```
[Table]
public class Photo
{
[Column(IsDbGenerated = true, IsPrimaryKey = true, CanBeNull = false)]
public int ID { get; set; }
[Column(CanBeNull = false)]
public string Filename { get; set; }
[Column(CanBeNull = false)]
public string Description { get; set; }
[Column(CanBeNull = false)]
public DateTime DateTaken { get; set; }
public List<string> Tags { get; set; }
public override string ToString()
{
string result = String.Format("File: {0}, Desc: {1}, Date: {2}, Tags: ",
Filename, Description, DateTaken);
if (Tags != null)
foreach (string tag in Tags)
result += tag + ", ";
return result;
}
}
```
You will notice that currently I do not have any attributes for the `Tags` list. I would like to be able to setup the attributes (associations) for the `Tags` list so that it would be populated with `Name` field of the `Tag` table for all entries in the `Tag` table of a particular `PhotoID`. It would be preferable if I could do this directly (i.e. without having to setup a `Tag` class mimicking/relating to the `Tag` table). Since I'm only interested in one field (the Name in the Tag table) rather than many fields, I would think there is a way to do this.
Is this possible, and if so how would I further decorate the class with attributes and what would be the syntax for a simiple Select query using LINQ-to-SQL?
If it helps, here is the code I am using to simply add a new photo and then grab all of the photos out of the database (obviously the tag information is not pulled out as the code stands now).
```
DataContext context = new DataContext(connectionString);
// add new photo
Photo newPhoto = new Photo { Filename = "MyImage1.jpg", Description = "Me", DateTaken = DateTime.Now };
context.GetTable<Photo>().InsertOnSubmit(newPhoto);
context.SubmitChanges();
// print out all photos
var photoQuery = from m in context.GetTable<Photo>() select m;
foreach (Photo myPhoto in photoQuery)
textBox1.Text += Environment.NewLine + myPhoto.ToString();
```

Hooray for pictures! Here's what it looks like when assigning the picture to the background, and when not.
I'd very much like for it to not stretch out the top `TableView` if the image is larger than the table. I've included an empty "view" to give a little bit of extra space for the table's background already as well, as you can see in the XML to follow. Tried to mess around with ScaleType, but that was a wash.
How can I get the BG to stretch to fit the layout? I'm trying to handle the "user xxx has a smaller screen than WVGA" gracefully. I lack grace, apparently.
```
<TableLayout
android:id="@+id/widget29"

<TextView android:id="@+id/armedText" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Unarmed!" android:gravity="right" android:layout_weight="3" />
</TableRow>
</TableLayout>
```
The tablelayout is the first element of the root linearLayout, if that matters at all.
Edit: Alternatively, if you know how I could measure the tableLayout's X and Y space before assigning the image, I could scale it programmatically before assigning it.... Either solution would be good if anyone knows!

Hello all,
I am working on a program which determines the average colony size of yeast from a photograph, and it is working fine with the .bmp images I tested it on. The program uses pygame, and might use PIL later.
However, the camera/software combo we use in my lab will only save 16-bit grayscale tiff's, and pygame does not seem to be able to recognize 16-bit tiff's, only 8-bit. I have been reading up for the last few hours on easy ways around this, but even the Python Imaging Library does not seem to be able to work with 16-bit .tiff's, I've tried and I get "IOError: cannot identify image file".
```
import Image
img = Image.open("01 WT mm.tif")
```
My ultimate goal is to have this program be user-friendly and easy to install, so I'm trying to avoid adding additional modules or requiring people to install ImageMagick or something.
Does anyone know a simple workaround to this problem using freeware or pure python? I don't know too much about images: bit-depth manipulation is out of my scope. But I am fairly sure that I don't need all 16 bits, and that probably only around 8 actually have real data anyway. In fact, I once used ImageMagick to try to convert them, and this resulted in an all-white image: I've since read that I should use the command "-auto-levels" because the data does not actually encompass the 16-bit range.
I greatly appreciate your help, and apologize for my lack of knowledge.
P.S.: Does anyone have any tips on how to make my Python program easy for non-programmers to install? Is there a way, for example, to somehow bundle it with Python and pygame so it's only one install? Can this be done for both Windows and Mac? Thank you.
EDIT: I tried to open it in GIMP, and got 3 errors:
1) Incorrect count for field "DateTime" (27, expecting 20); tag trimmed
2) Sorry, can not handle images with 12-bit samples
3) Unsupported layout, no RGBA loader
What does this mean and how do I fit it?

Here's a [screenshot](http://www.laranevans.com/BadScrollbar.png) of the problem.
Basically, when the scrollbar shows up for the y-axis, the width of the container doesn't expand. Instead it just creates a scrollbar for the x-axis.
How can I get the container to expand without creating the x-axis scrollbar?

I'm working on a social web-site project and I need to list "First, Second and Third Degree Contacts" of my contacts. I'm using SQL Server AND C#
Assume a `contact` table like this:
For first degree contact:
- `gulsah``burak,sennur`
Query I use to select this:
```
SELECT contact_2 FROM Contacts_Table WHERE contact_1 like 'gulsah'
```
For second degree contact:
If `gulsah` is me again then my second degree contacts are: `mali`
What makes it difficult is to select contacts of my contacts who are not my first degree contact.
I can select mutual contacts but I guess it is not the right approach.
For example, to select mutual contacts of me (`gulsah`) and `burak`:
```
SELECT contact_1 FROM (SELECT * FROM Contact_Test
WHERE contact_2 like 'burak') a
INNER JOIN (SELECT contact_1 FROM Contact_Test
WHERE (contact_2 = 'gulsah')) b
ON a.contact_1 = b.contact_1
```
This query works but as I said, it's not the right approach for this job.
For third degree contact:
If `gulsah` is me again then my third degree contacts are_ `mehmet,ahmet`
I need to select contacts of my contacts' contacts who are not my first and second degree contact :)
[Here is a post from Linkedin which explains contact level.](http://www.linkedin.com/answers/administration/customer-service/ADM_CSV/581967-23863639)
Thanks for responses.

I remember successfully doing this countless times before with a bit of trial and error, but after a new reinstall of Snow Leopard, I would like to just ask the Stackoverflow community this for once and for all...
I installed Netbeans 7 (for C++). For some reason, I didn't see any way to install Python plugins here, so I installed Netbeans 6.5. It automatically detects Python 2.5 on the system, but darnit I want Python 3, which it cannot automatically detect. So now I go to Tools > Python Platforms, click on New, and which file do I select in the new window?
EDIT: I found this when looking in `usr/bin/`.
EDIT: For my own future reference, in Eclipse at least, `/Library/Frameworks/Python.framework/Versions/3.2/Resources/Python.app/Contents/MacOS/Python`
I found the alias in `.../3.2/bin/python3.2`

While coding with UITableView, I encounter this bug that I couldn't understand. I got 3 rows for my table and setting 50px for each row, except the 2nd row that I set it 500px which fill the whole screen. Problem comes when I scroll down to bottom, my bottom role is repeating first row appearance.This is my custom code:
```
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return 3;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"TestTable";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
if (indexPath.section ==0 && indexPath.row==0) {
cell.contentView.backgroundColor = [UIColor redColor];
}
if (indexPath.section ==0 && indexPath.row==1) {
cell.contentView.backgroundColor = [UIColor blueColor];
}
if (indexPath.section ==0 && indexPath.row==2) {
cell.contentView.backgroundColor = [UIColor greenColor];
}
}
// Configure the cell...
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row==1) {
return 400;
}
return 50;
}
```
According to the code, first row is red color, second role is red and third one is blue. But my last row is red color (repeating the first row). If I set my 2nd row to shorter than the screen, e.g. 100px, third row loading fine.

Appreciate for all kind of advice, as I am running out of ideas how is this happening.

How can i make a primary key of a table be auto incremented automatically? Where is that option? i don't see it in my interface anywhere.
How can i create a relationship between 2 tables? I think i am doing it correctly, but i don't see any sign that i did things right:
This is how i start creating the relationship:
Then i configure the relationship with the wizard:
But at the end i don't see any icon or symbol that indicates me that this is a relationship:

I prefer the screenshot over the plain text version because it looks more visually appealing.

Hey guys, I am storing a time stamp in my iPhone app via Core Data, I have had success doing it in the past storing a double value as an INT 64 type in Core Data. However, I just recently had to change it to an NSNumber instance instead of a primitive double type and ever since I have not been able to get Core Data to store and retrieve the same numeric value (the following are attempts with different numeric attribute types within Core Data):
The code that generates this console output is the following:
```
NSLog(@"VALUE BEING STORED: %@",[NSNumber numberWithDouble:tmeStmp]);
[[CoreDataSingleton sharedManager] setItemInDFMWhilePreservingEntityUniquenessForItem:timeStampAttr withValue:[NSNumber numberWithDouble:tmeStmp]];
[[CoreDataSingleton sharedManager] saveStore];
NSLog(@"VALUE RETRIEVED FROM STORE: %@",[[CoreDataSingleton sharedManager] getTimeStamp]);
```
Relevant parts of `setItemInDFMWhilePreservingEntityUniquenessForItem:withValue:`:
```
-(void)setItemInDFMWhilePreservingEntityUniquenessForItem:(attribute)attr withValue:(id)value {
//...
} else if (attr == timeStampAttr) {
[dfm setTimeStamp:value];
}
//...
} else if (attr == timeStampAttr) {
[[fetchedObjects objectAtIndex:0] setTimeStamp:value];
}
//...
}
```
Relevant parts of `getTimeStamp`:
```
-(NSNumber *)getTimeStamp {
//...
NSNumber *returnable = [[[NSNumber alloc] initWithDouble:(NSInteger)[[fetchedObjects objectAtIndex:0] valueForKey:@"timeStamp"]] autorelease];
return returnable;
}
```
I am thinking that I am most likely not converting between numeric types adequately, but I have fudged around with the code for hours with no luck. Any idea where I am going wrong? Thanks!

I am struck with a problem. I want to convert the CMAttitude information of an iPhone to Altitude (0 to 90deg) and Azimuth (0 to 360 deg). I have googled around and hit some threads which discuss about it, but none of threads turn out with a positive answer and most of the articles discussing Quaternion and Euler angles are too much mathematics to stuff into my brain!
Is there some open source material which does this task easy? Or someone has written code to perform this conversion?
Edit:
First off, sorry for being so abstract!
Azimuth is the direction on the surface of the earth towards which the device is pointing. Like North = 0 deg, North East = 45deg, East = 90 deg, South = 180 deg and so on. Ranges between 0 deg to 360 deg:
Altitude is the angle made from the plane of the earth to an object in the sky:
Thanks,
Raj

While looking at the [belisarius](https://stackoverflow.com/users/353410/belisarius)'s question about [generation of non-singular integer matrices with uniform distribution of its elements](https://stackoverflow.com/questions/5131987/generating-random-non-singular-integer-matrices), I was studying a paper by Dana Randal, "[Efficient generation of random non-singular matrices](http://www.eecs.berkeley.edu/Pubs/TechRpts/1991/CSD-91-658.pdf)". The algorithm proposed is recursive, and involves generating a matrix of lower dimension and assigning it to a given minor. I used combinations of `Insert` and `Transpose` to do it, but there are must be more efficient ways of doing it. How would you do it?
The following is the code:
```
Clear[Gen];
Gen[p_, 1] := {{{1}}, RandomInteger[{1, p - 1}, {1, 1}]};
Gen[p_, n_] := Module[{v, r, aa, tt, afr, am, tm},
While[True,
v = RandomInteger[{0, p - 1}, n];
r = LengthWhile[v, # == 0 &] + 1;
If[r <= n, Break[]]
];
afr = UnitVector[n, r];
{am, tm} = Gen[p, n - 1];
{Insert[
Transpose[
Insert[Transpose[am], RandomInteger[{0, p - 1}, n - 1], r]], afr,
1], Insert[
Transpose[Insert[Transpose[tm], ConstantArray[0, n - 1], r]], v,
r]}
]
NonSingularRandomMatrix[p_?PrimeQ, n_] := Mod[Dot @@ Gen[p, n], p]
```
It does generate a non-singular matrix, and has uniform distribution of matrix elements, but requires p to be prime:
The code is also not every efficient, which is, I suspect due to my inefficient matrix constructors:
```
In[10]:= Timing[NonSingularRandomMatrix[101, 300];]
Out[10]= {0.421, Null}
```
---
So let me condense my question. The minor matrix of a given matrix `m` can be computed as follows:
```
MinorMatrix[m_?MatrixQ, {i_, j_}] :=
Drop[Transpose[Drop[Transpose[m], {j}]], {i}]
```
It is the original matrix with `i`-th row and `j`-th column deleted.
I now need to create a matrix of size `n` by `n` that will have the given minor matrix `mm` at position `{i,j}`. What I used in the algorithm was:
```
ExpandMinor[minmat_, {i_, j_}, v1_,
v2_] /; {Length[v1] - 1, Length[v2]} == Dimensions[minmat] :=
Insert[Transpose[Insert[Transpose[minmat], v2, j]], v1, i]
```
Example:
```
In[31]:= ExpandMinor[
IdentityMatrix[4], {2, 3}, {1, 2, 3, 4, 5}, {2, 3, 4, 4}]
Out[31]= {{1, 0, 2, 0, 0}, {1, 2, 3, 4, 5}, {0, 1, 3, 0, 0}, {0, 0, 4,
1, 0}, {0, 0, 4, 0, 1}}
```
I am hoping this can be done more efficiently, which is what I am soliciting in the question.

Per blisarius's suggestion I looked into implementing `ExpandMinor` via `ArrayFlatten`.
```
Clear[ExpandMinorAlt];
ExpandMinorAlt[m_, {i_ /; i > 1, j_}, v1_,
v2_] /; {Length[v1] - 1, Length[v2]} == Dimensions[m] :=
ArrayFlatten[{
{Part[m, ;; i - 1, ;; j - 1], Transpose@{v2[[;; i - 1]]},
Part[m, ;; i - 1, j ;;]},
{{v1[[;; j - 1]]}, {{v1[[j]]}}, {v1[[j + 1 ;;]]}},
{Part[m, i ;;, ;; j - 1], Transpose@{v2[[i ;;]]}, Part[m, i ;;, j ;;]}
}]
ExpandMinorAlt[m_, {1, j_}, v1_,
v2_] /; {Length[v1] - 1, Length[v2]} == Dimensions[m] :=
ArrayFlatten[{
{{v1[[;; j - 1]]}, {{v1[[j]]}}, {v1[[j + 1 ;;]]}},
{Part[m, All, ;; j - 1], Transpose@{v2}, Part[m, All, j ;;]}
}]
In[192]:= dim = 5;
mm = RandomInteger[{-5, 5}, {dim, dim}];
v1 = RandomInteger[{-5, 5}, dim + 1];
v2 = RandomInteger[{-5, 5}, dim];
In[196]:=
Table[ExpandMinor[mm, {i, j}, v1, v2] ==
ExpandMinorAlt[mm, {i, j}, v1, v2], {i, dim}, {j, dim}] //
Flatten // DeleteDuplicates
Out[196]= {True}
```

I have two Combo-Boxes like this
I need to create an auto-fill feature for the 1st Combo-Box. It should list the EmployeeID if Search-By Field is specified as Employee-Number. Similarly it should list Employee First Name along with Last Name if the Search-By Field is Employee-Name.
How can I do this? I have no clue, I am doing this for the first time. I am using SQLite, Visual Studio 2010.
```
Dim mySelectQuery As String = "SELECT " & Search & " FROM EmployeeTable WHERE Status LIKE '" & Status & "'"
Dim myConnString As String = "Data Source=" & Application.StartupPath & "\Database\SimpleDB.db3"
Dim sqConnection As New SQLiteConnection(myConnString)
Dim sqCommand As New SQLiteCommand(mySelectQuery, sqConnection)
sqConnection.Open()
Try
' Always call Read before accessing data.
Dim sqReader As SQLiteDataReader = sqCommand.ExecuteReader()
Dim j As Integer = sqReader.FieldCount
While sqReader.Read()
'''''''''''''''''''''''Here, Don't know how to list the items from the query reult into the combo-box
End While
'Close Reader after use
sqReader.Close()
Catch ex As Exception
'Show Message on Error
MsgBox(ex.ToString)
Finally
'At Last Close the Connection
sqConnection.Close()
End Try
```

Hey, I have a Gallery in a ScrollView, the problem is that when in Landscape, the images are not scaled to fill the screen, Here is a screenshot:  (ignore the toast)
As you can see the image in the middle is the one that is currently selected, but you can see that in the left/right sides of the screen parts of the next/previous images are also displayed.. how can I make the image in the middle get scaled to the whole screen?
ImageAdapter class:
```
public class ImageAdapter extends BaseAdapter {
int mGalleryItemBackground;
int counter =0 ;
private Context mContext;
public String[] mImageIds;
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = c.obtainStyledAttributes(R.styleable.Gallery1);
mGalleryItemBackground = a.getResourceId(R.styleable.Gallery1_android_galleryItemBackground, 0);
a.recycle();
}
public void insert(String string)
{
mImageIds[counter]=string;
counter++;
}
public int getCount() {
return mImageIds.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView i = new ImageView(mContext);
i.setImageBitmap(BitmapFactory.decodeFile(mImageIds[position]));
i.setScaleType(ImageView.ScaleType.FIT_XY);
i.setBackgroundResource(mGalleryItemBackground);
return i;
}
}
```
xml:
```

It is really annoying that when I run a select command in SQL*Plus such as:
```
SELECT * FROM books;
```
The output is really badly formatted and unreadable (row cells are not in a row but separated by line breaks etc):
How can I configure it to show SELECT results in a nicer way?
EDIT:
This is my login.sql file contents:
```
SET ECHO OFF
SET SERVEROUTPUT ON SIZE 1000000
SET PAGESIZE 999
SET LINESIZE 132
```
EDIT2:
Affer increasing the LINESIZE:
```
SET LINESIZE 32000
```
It now looks like this:

I want to create a table row, which on the left are 3 images, and on the right a textview.
Something You can usually see in a game (on the right the level number, and on the left the number of lives left.)
I have tried this layout, but one of the images isnt aligns to the right: (The table layout is nested within linear layout)
```
<TableLayout

I have this Ir image that has captured the veins under the skin. I want to process this image so as to retain just the veins as black colour and get everything else as white. Then I want to generate the coordinate pixels as these black pixels which will be the veins.
This is what I have done till now :
```
a=imread('11.jpg');
figure(1),imshow(a);
title('original image');
cform = makecform('srgb2lab');
for ii = 1:3
a(:,:,ii) = medfilt2(a(:,:,ii),[5 5]);
end
lab = applycform(a,cform);
figure(2),imshow(lab);
title('ímage in color space after filtering');
b=lab(:,:,1);
c=im2bw(b,0.2);
figure(3),imshow(c);
title('b&white boundry of fist');
neg=1-c;
figure(4),imshow(neg);
color=a;
r=color(:,:,1);
r(~c)= 0;
g = color(:,:,2);
g(~c)= 0;
b = color(:,:,3);
b(~c)= 0;
% Concatenate in the "3rd dimension" to re-constitute an RGB image.
color = cat(3,r,g,b);
figure(5),
imshow(color);
title('reconstructed fist with black bg');
gray=rgb2gray(color);
figure(6);
imshow(gray);
title('grayscale of fist');
i1=imresize(gray,[256 256],'bilinear');
figure(7);
imshow(i1);
title('Resized Image of grayscale');
figure(8),imhist(i1);
title('histogram of resized grayscale');
i2=histeq(i1,256);
figure(9),imshow(i2);
title('histogram equalisatio');
figure(10),imhist(i2);
title('équalised histogram');
e=medfilt2(i2,[5 5]);
figure(7),imshow(e);
f=medfilt2(e,[5 5]);
figure(8),imshow(f);
g=medfilt2(f,[5 5]);
figure(9),imshow(g);
s=g;
figure(10),imshow(s);
l=imresize(s,[200 200]);
figure(11);
imshow(l);
[h,u]=size(l);
smth=double(l);
wl=1.5;
we=3;
wt=15;
eline=smth;;
[grady,gradx]=gradient(smth);
eedge=-1*sqrt((gradx.*gradx+grady.*grady));
figure(12);
imshow(uint8(-eedge));
m1=[-1 1];
m2=[-1;1];
m3=[1 -2 1];
m4=[1;-2;1];
m5=[1 -1;-1 1];
cx=conv2(smth,m1,'same');
cy=conv2(smth,m2,'same');
cxx=conv2(smth,m3,'same');
cyy=conv2(smth,m4,'same');
cxy=conv2(smth,m5,'same');
for i=1:h
for j=1:u
eterm(i,j)=(cyy(i,j)*cx(i,j)*cx(i,j)-2*cxy(i,j)*cx(i,j)*cy(i,j)+cxx(i,j)*cy(i,j)*cy(i,j))/((1+cx(i,j)*cx(i,j)+cy(i,j)*cy(i,j))^1.5);
end
end
figure(13);
imshow(uint8(-eterm));
eext=(wl*eline+we*eedge+wt*eterm);
figure(14);
imshow(uint8(eext));
eext=(wl*eline+we*eedge);
figure(15);
imshow(uint8(eext));
whos eext;
```
and this is the image:
So how do I proceed after this so that I retain the veins as black and eveything else as white?
So this is the image after median filtering, as you can see the veins are quite dark. So how do I proceed from here so that the veins are retained as black and everything else as white?

I am trying to compute a polygon that surrounds a line connecting multiple points (e.g. a GPX track).
The image below shows an example with the track as red line and the desired polygon in blue.
As simplification the red points are denoted by x and y - not by latitude/longitude.
How do I compute such an environment (light blue polygon) if I only have the list of the three points specifying the path?
Partial solutions (e.g. for only two points) or hints about mathematical libraries (in Java) that provide algorithms for such a computation would also bring me one step forward.
Further assumptions:
-
Using the approach as presented by Rogach and xan I ran into some problems if the angle between the lines is smaller than 90 degree or larger than 270 degree:
As you can see the polygon gets intersects itself which leads to a serious problem.
From my point of view using an `java.awt.geom.Area` is the better approach:
For each line connecting two points of the track I compute a surrounding polygon. Afterwards I add (area union) the computed polygon to an Area which does all the necessary computation for me. As the Area strictly uses the "or" algorithm on adding new polygons I do not have to care about "self intersections" of the polygon as presented in the update above.
```
Area area = new Area();
for (int i = 1; i < points.size(); i++) {
Point2D point1 = points.get(i - 1);
Point2D point2 = points.get(i);
Line2D.Double ln = new Line2D.Double(point1.getX(), point1.getY(), point2.getX(), point2.getY());
double indent = 15.0; // distance from central line
double length = ln.getP1().distance(ln.getP2());
double dx_li = (ln.getX2() - ln.getX1()) / length * indent;
double dy_li = (ln.getY2() - ln.getY1()) / length * indent;
// moved p1 point
double p1X = ln.getX1() - dx_li;
double p1Y = ln.getY1() - dy_li;
// line moved to the left
double lX1 = ln.getX1() - dy_li;
double lY1 = ln.getY1() + dx_li;
double lX2 = ln.getX2() - dy_li;
double lY2 = ln.getY2() + dx_li;
// moved p2 point
double p2X = ln.getX2() + dx_li;
double p2Y = ln.getY2() + dy_li;
// line moved to the right
double rX1_ = ln.getX1() + dy_li;
double rY1 = ln.getY1() - dx_li;
double rX2 = ln.getX2() + dy_li;
double rY2 = ln.getY2() - dx_li;
Path2D p = new Path2D.Double();
p.moveTo(lX1, lY1);
p.lineTo(lX2, lY2);
p.lineTo(p2X, p2Y);
p.lineTo(rX2, rY2);
p.lineTo(rX1_, rY1);
p.lineTo(p1X, p1Y);
p.lineTo(lX1, lY1);
area.add(new Area(p));
}
```

If I call RED the statement will pull Fruit and Food, but instead I would like to structure the query to only pull the very next node to RED only which is "Fruit", don't need root node "Food".

I have a small gray-scale image with a number on it. In order to try my OCR method on it I have to convert it into binary.
If I use cvThreshold with 127 as threshold the image looks all screwed up because of the gradient around the skeletons of the number. I tried but could not find any image sharpening functions to use before applying the threshold.
Does anyone have pointers please?
 becomes  which is crude.
EDIT: by binary, I mean binary image, where a pixel in the image is either 0 (black) or 255 (white).
EDIT2: Oh, looking at the revision log made me giggle.

This is probably a very easy problem to solve but i have not succeeded. I have copied the file "questions_famquiz_easy_110326.txt" to the resources folder and now want to access (read) it and NSLog it to see that i am able to read it.
The code below is from one of the tests i have done based on examples that i have found on the web.
I am trying to access a txt-file in the Resources folder and fail to do so. I have searched for a solution, tested a lot, but not succeeded.
I am testing with the following code:
```
NSLog(@"\n \n >>>>>>viewDidLoad<<<<<<<<<");
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *docsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [docsDirectory stringByAppendingPathComponent:@"questions_famquiz_easy_110326.txt"];
if(![fileManager fileExistsAtPath:filePath])
{
NSData *data = [NSData dataWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/questions_famquiz_easy_110326.txt"]];
[data writeToFile:filePath atomically:YES];
}
NSString *myString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
NSLog(@"myString: %@", myString);
NSLog(@"\n \n>>>>>>DONE WITH viewDidLoad<<<<<<<<<");
exit(0); //====EXIT JUST FOR THE TEST====<<<
```
The above code is located in the first viewController that is started.
The output i get is:
```
>>>>>>viewDidLoad<<<<<<<<<
2011-04-24 21:53:47.825 FamQuiz_R0_1[542:307] myString: (null)
2011-04-24 21:53:51.044 FamQuiz_R0_1[542:307]
>>>>>>DONE WITH viewDidLoad<<<<<<<<<
```
Could someone nice help me to solve this?
update:
Here is the filePath:
```
2011-04-24 22:38:08.562 FamQuiz_R0_1[637:307] filePath: /var/mobile/Applications/7F5FDB03-0D22-46BC-91BC-4D268EB4BBEB/FamQuiz_R0_1.app/questions_famquiz_easy_110326.txt
```
Here is where i have placed the file:
```
NSString *myString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
```
When i used the above it did not work, when i used the below it worked and printed out the text.
```
NSString *myString = [[NSString alloc] initWithContentsOfFile:filePath];

I have developed a photo sharing community site using CodeIgniter 1.7. Photos that are uploaded by members are automatically resized in a number of formats, for which I use the CodeIgniter Image Manipulation class. This class is built into the framework and basically a wrapper around multiple image manipulation libraries, such as GD, GD2, ImageMagick, and NETPBM. On my host, I can only make use of GD2, so that's where this question will be about.
On to my problem. Here is an example of a resized photo on my site. Note that the original was very large, over 3000px wide:
[http://www.jungledragon.com/image/195/female_impala_close-up.html](http://www.jungledragon.com/image/195/female_impala_close-up.html)
Now, look at that same image, also resized, just a bit larger at Flickr:
[http://www.flickr.com/photos/fledder/3763538865/in/set-72157621744113979](http://www.flickr.com/photos/fledder/3763538865/in/set-72157621744113979)
See the dramatic difference? I'm trying to bridge that huge gap. The first thing I did was to apply a sharpen filter to the images. You can see the result here:
Although still not perfect, it at least approaches the sharpness level of the Flickr image. The remaining problem is that the colors are washed away, as if their saturation is decreased. This happens before the sharpening filter already, so it must be in GD2.
This issue is vitally important to me, but I don't know where to look. I've found some .NET threads talking about chroma sub sampling but I don't know what to do with that information in my setup. I'm looking for any solution that works within the constraints of my setup.

: I'm shocked. In a good way. It took me a lot of pain to install ImageMagick but after switching to it (which was a matter of setting 'imagemagick' as the library to use at the Code Igniter image manipulation class, the result of the test image is as follow:
ImageMagick's resizing is doing it exactly as intended. The colors are preserved, and the sharpness is there. Yes, I disabled my custom sharpening routine since it is no longer needed due to ImageMagick. On top of that, the process is a lot faster and less memory hungry too. And here comes another great part: I cannot explain it, but I did absolutely nothing to tell ImageMagick to use a specific color profile, which was suggested by user @Alix. In my testing so far it looks like the color information is respected with or without an embedded profile. The output simply is a smaller version of the input. Is ImageMagick really that smart or am I dreaming?

Note: I apologize if this program is painful to look at. this is my first program using derived classes. I plan on submitting it to code review after I get it to do what I want so I can recieve tips on how it could have been designed better. Feel free to provide those tips here but my main intention for this post is to get it to work correctly.
This program processes withdrawals and deposits for bank accounts and then applies an interest rate.
For some reason it seems like the value of checkingBalance gets stuck and does not update to a new value throughout the rest of the loop when processing the accounts of class type "checkingAccount". It is odd because the same loop is used to process the other derived class "savingsAccount" and it works fine and one of accounts of type "checkingAccount" even seems to have been processed correctly so I am completely bamboozled as to what is going on.
If anyone could lend a hand and help me resolve this issue it would be greatly appreciated. Please do not hesitate to ask me to specify anything, I will respond asap.

//This loop is exited early:
for (int j = 0; j < transactionNum; j++)

}
//when something in here occurs?
// c = j from loop

# What I plan on doing:
I want to develop the [English accent](http://en.wikipedia.org/wiki/English_accent) (without professional training).
# Set of axioms behind my reasoning with executive summary:
Following is knowingly over simplified, sorry for that. I tried to keep question short.
## Part 1 : Understanding how learning works.
At the moment I assume, that [Broca's area](http://en.wikipedia.org/wiki/Broca%27s_area) and [Wernicke's area](http://en.wikipedia.org/wiki/Wernicke%27s_area) must be aware of the language, and muscle memory with existing phonetic alphabet will build the speech. Accents are just formed naturally over time by phonetic alphabet assimilation.
Using Google I found, that [speech shadowing](http://en.wikipedia.org/wiki/Speech_shadowing), can potentially be used for phonetic symbol assimilation. Muscle memory on the other hand can be trained by repetitive action. And this is most effective, if person is of 23-24 years of age and has lots of uninterpretable time on his/her hand as losing focus can dramatically decrease effective learning curve gradient. This kind of [procedural memory](http://en.wikipedia.org/wiki/Procedural_memories) can be probably optimized to flushed in [memory with designed sleep pattern](http://en.wikipedia.org/wiki/Sleep_and_learning).
## Part 2 : Designing behavioral pattern
- - -
## Part 3 : Finding a fluent speaker whom accent I want to sound like.
Youtube is a powerful free resource. Sample audio, that I tough about picking :
[Someone Like You - Adele (Cover)](http://www.youtube.com/p/57025F8AB5E8E795?hl=en_US&fs=1) in HD.
It does not bother me, that it is high pitched female voice.
## Part 4 : Distinguishing target accent phonemes and phones.
It is not a trivial task - identifying and judging whether spoken phone is correct. And how correctly tangible text is spoken by human. It seems so complex in fact, that I wont bother automating it and just use [IPA](http://en.wikipedia.org/wiki/IPA) as baseline.
Here is the first psalm with word stress in american IPA of the sample audio above :
No copyright infringement intended. And image is created with [upodn](http://upodn.com/phon.asp) (alternative: [photransedit](http://www.photransedit.com/Online/Text2Phonetics.aspx)).
## Part 5 : Training muscle memory to produce target accent.
Although it is fun to just try to mimic and archive synchronization, then i would prefer building a tool, that extracts words as audio files. So I can use winamp or ipod to loop and shuffle the words I want.
I imagine, that I can use MS Expression Encoder for this.
# Question
If given an audio file (ex. in wav format, size < 32mb) and it's text equivalent (finite nr of words, ex. 2000), then how to split it into multiple files, that each contains 1 word. Word can contain some excess whitespace, and boundary checks can be user approved. If it is not accurate, then what is the best way, to get good estimation for word boundaries.
Main intention is to reduce work, that I would be doing, if this would be done manually.

I'm working on a site where users can describe a physical object using (amongst many other things) any color in the rgb 0-255 range. We offer some simplified palettes for easy clicking but a full color wheel is a requirement.
Behind the scenes, one of the processes compares two user descriptions of the object and scores them for similarity.
What I'm trying to do is get a score for how similar the 2 colors are . Basically, the algorithm needs to determine if a 2 humans picking 2 different colors could be describing the same object. Thus Light Red->Red should be 100%, Most of the shades of grey will be 100% to each other, etc but red-> green is definitely not a match.
To get a decent look at how the algorithms were working, I plotted grayscale and 3 intensities of each hue against every other color in the set and indicated no match (0%) with black, visually identical (100%) with white and grayscale to indicate the intermediate values.
My first (very simplistic approach) was to simply treat the RGB values as co-ordinates in the colour cube and work out the distance (magnitude of the vector) between them.
This threw out a number of problems with regards to Black->50% Grey being a larger distance than (say) Black->50% Blue. having run hundreds of comparisons and asked for feedback, this doesn't seem to match human perception (shown below)
Method 2 converted the RGB values into [HSV](http://en.wikipedia.org/wiki/HSL_and_HSV). I then generated a score based 80% on hue with the other 20% on Sat/Lum. This seems to be the best method so far but still throws some odd matches
Method 3 was an attempt at a hybrid - HSL Values were calculated but the final score was based upon the distance between the 2 colors in the HSL color cylinder space (as in 3D polar co-ordinates).
I feel like I must be re-inventing the wheel - surely this has been done before? I can't find any decent examples on Google and as you can see my approach leaves something to be desired.
So, my question is:
Is there a standard way to do this? If so, how? If not, can anyone suggest a way to improve my approach? I can provide code snippets if required but be warned it's currently messy as hell due to 3 days of tweaking.
Using the suggestions provided below, I've implemented a `Delta E 2000` comparer. I've had to tweak the weighting values to be quite large - I'm not looking for colors which are imperceptibly different but which are not hugely different. In case anyone's interested, the resulting plot is below...

A legacy website that I am working on has a popup box that uses an iFrame and has nested tables. Within the cells of this table there is simple text and the last row of the table has two input boxes; one left aligned and one right aligned.
On screen resolution higher than 1024 X 768 everything is displayed within the borders of the box. The problem lies when I have resolution of 1024 X 768 or lower the text expands wider then the box and therefore horizontal scroll bars are turned on. I like to modify the inline css styling that so prominent in this design so the text and buttons render the same in any resolution and no scroll bars are turned on.
The only thing I can see is that table width is set to 100%.
Any help will be a life saver.
Thanks
Please find screenshots attached:

I'm implementing a fairly standard `UIView` animation, using `UIViewAnimationTransitionCurlUp`. The basic idea is that I have a folder on the screen covered with a stack of pages, and as I change from page to page I use the curl up animation. Each page is a subview that takes up about 70% of the screen so that the clipboard is still visible in the background.
This animation all works fine, that problem is that even though each "page" (which is a separate `UIViewController` & `UIView`) has a transparent background, the page background becomes visible during the page curl. It's only slightly visible, like a black background with an alpha of 0.1. But it ruins the effect.
Any ideas? This is for a private application that will not be distributed on the app store, so private APIs are ok.

I'm creating a page with [jQuery Mobile](http://jquerymobile.com) and I have the following HTML:
```
<div data-role="page" id="page1">
<div data-role="header">
<h1>Page 1</h1>
</div>
<div data-role="content">
<p>You need to select a page:</p>
<ol data-role="listview">
<li><a href="#page2">Item 1</a></li>
<li><a href="#page2">Item 2</a></li>
</ol>
</div>
</div>
<div data-role="page" id="page2">
<div data-role="header">
<h1>Page 2</h1>
</div>
</div>
```
It behaves as expected, except that on Chrome 10.0.648.205, I see the following:
Notice that the `<p>` is obscured by the list. Why is the list overlapping the text?
you can play with the code here: [http://jsfiddle.net/r2whr/](http://jsfiddle.net/r2whr/)

Why is this listview positioned above the previous <p>?

I have a button with a default command and a context menu for other available commands:
```
<Button Content="Do this" Height="23" Width="75" Command="local:MyCommands.ThisCommand">
<Button.ContextMenu>
<ContextMenu>
<MenuItem Header="Do this" Command="local:MyCommands.ThisCommand" />
<MenuItem Header="Do that" Command="local:MyCommands.ThatCommand" />
</ContextMenu>
</Button.ContextMenu>
</Button>
```
By default, the context menu appears starting at the hot spot of the cursor:
However, I'd like it to appear at a fixed relative position, beneath the button (fake, edited screenshot):
Setting the context menu's `Placement`, `PlacementRectangle` and `PlacementTarget` properties doesn't seem to do anything; the context menu insists on hanging off the cursor wherever I right-click my button. Worse, focusing the button and hitting the [menu key](http://en.wikipedia.org/wiki/Menu_key) causes the context menu to sit in front of the button, blocking it completely.
So, how exactly do I specify that the context menu should appear beneath the button?
|
How can I tell a ContextMenu to place itself relatively to its control and not the cursor?

I designed a pretty cool looking form layout but have no clue how to make the radios on it work! Below is a mockup of the the form:
I've already created the CSS for the text inputs (and will attach it below for anyone else looking for something similar). What I now need to figure out is the "What service are you looking for?" section. I've written the CSS for the blue box but I now need to figure out how to turn "Consulting, Web Development, and Graphic Design" into radio selects where the one with the check mark next to it is the selected radio box. Way over my head. I'm still trying to figure it out and will post back here if I do; just looking for some input on how you'd write those radios.
Current code for text inputs:
```
input[type=text] {
width: 365px;
height: 54px;
margin: 0 0 12px 0;
padding: 0 0 0 25px;
-webkit-border-radius: 15px;
-moz-border-radius: 15px;
border-radius: 15px;

I need to make the ListBox expand to fit the width it has available. Here's the XAML:
```
<ListBox Grid.Row="2" Height="400" ItemsSource="{StaticResource Notes}" VerticalAlignment="Top">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical" Height="90" Margin="5">
<TextBlock Text="{Binding Title}" FontSize="30" />
<TextBlock Text="{Binding Text}" FontSize="15" />
<Rectangle Fill="#1192D4" Height="2" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
```
|
How can I make a ListBox expand to fit the entire available width?

I'm trying to run a Ruby on Rails app on a Dreamhost shared server. All is well so far except one weird bug I have not been able to unravel.
Sometimes when I visit the web app, I get presented with a Phusion Passenger error saying,
> You have already activated rack 1.2.1, but your Gemfile requires rack 1.2.2. Consider using bundle exec.
When I just refresh the page it seems to work, though - no more Phusion Passenger error message.
Following other stack overflow threads and a similar [Dreamhost wiki](http://wiki.dreamhost.com/Ruby_on_Rails#Rails_2.3.5_-_Rack_1.0_already_activated_.28fix.29), I added the following to the top of the `config/environment.rb` file:
```
if ENV['RAILS_ENV'] == 'production' # don't bother on dev
ENV['GEM_PATH'] = '/home/myusername/.gems' + ':/usr/lib/ruby/gems/1.8'
end
```

I am trying to add a whole package to my svn ignore list.
I thought that putting `*ploo.syntax.analysis*` as pattern would be a match, but it seems as it isn't.
I've also tried without success:
- - -
Adding `*` or `analysis` or `*analysis*` will work, though (but that is not exactly what I intend to)
What am I doing wrong?

I have just moved to xcode4 and boy am i confused! :)
For one, in the screenshot, you could see the localizable strings, a couple of the file names changed to "null", i am wondering why and if it would effect the final product?
And also, i could'nt figure out for the life of me, how do i add another localization. Previously in xcode3.x i had to right click on "Localizable Strings" and add a language, where do i do it now?
Update: I have found where to add locations, but again, previously i was able to type a language the way i wanted, for instance, i want to add spanish, i could do that by just adding a language with name spanish, but now i am forced to choose from a predefined list of languages. And also, the ((null)) bugs me
