With this I can zoom and pan on a MultiScaleImage and add my custom Dot object to the DotCanvas canvas. Here's the XAML:
```

</Grid>
```
Now, the problem is that, since the Dots are placed in a canvas that's over the MultiScateImage (ZoomImage object) when I pan and zoom the Dots will stay in their respective place over the canvas. This code has some missed tries trying to keep the Dots on place while the image is panning and zooming.
Here's an image of the app, the blue dots around are my custom Dot object:
The main question is, how can I keep the Dots in their relative place over the image while the user zooms and pans.

I discovered that if I change the "Base SDK" to "iOS Simulator 3.2" (iPad ???) it does not give me this error when doing Build & Analyze... But this is supposed to be an iPhone App. I am running XCode 3.2.4... am I missing something when I create the Project? I am choosing iPhone as the target device, not sure what's going on.
I am having problems finding a memory leak in my iPhone App. I tried running "Build & Analyze", but when it gets to the MyApp_Prefix.pch file, it says "Analyzer skipped this file due to parse errors" - then 50% of the files after that say "Skipped this file due to parse errors - /var/folders/ ... /MyApp_Prefix.pch file not found".
The App actually compiles and runs, and the Prefix.pch file does exist.
When I open all the errors that appear under the first error, it starts opening files that are in the frameworks, which I don't know why there would be something wrong in there.
Here is the contents of the .pch file:
```
//
// Prefix header for all source files of the 'Tickets' target in the 'Tickets' project
//
#ifdef __OBJC__
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#endif
```
Here are the files that open when I click the 'expected function body after function declarator', 'expected type', etc...
CGPDFContext.h
UIView.h
UIApplication.h
UITextView.h
UIWebView.h
These are all located in the Frameworks.
I tried creating an entirely new project and importing my existing classes, and it gave me the same errors.
I tried running Build & Analyze on one of my older projects, which use the same Frameworks, and it runs fine.

: Main function is to receive the streamed video from the client and display it on the website in real time.
The users will be able to monitor their Webcams remotely by streaming their webcams output to a remote server that is accessible via the web. The system will also serve as a motion detection system (if activated by the user) to notify the users via email if any motion has been detected on their webcams. In addition the system also allows users to schedule recordings and watch them online through live streaming.

3,950,543 | 1 | 3,950,927 | null | 1 | 1,341 | I have to develop a CRUD application, that will be coded in php.
I have 3 main actors (Users, Administrators and Doctors -- this is for an hypothetical
hospital), each one with different Use Cases already defined.
Although I feel the Use Cases are more than enough to successfuly model the Class Diagram, I am being specifically asked to also include DataFlow Diagrams into the project's documentation.
I've been reading about DataFlow diagrams, and it seems you usually have first of all a Level 0 DataFlow Diagram, to which they call Context Diagram.
Being that this is basically a 3-tier application with 3 different Actors, how should I model the Context Diagram?
Being that a Context Diagram is supposed to just tell us what comes in and what comes out of our System, I can't imagine anything more interesting/descriptive than the following diagram:
Is this supposed to be something like this, or am I totally missing the point? This php page will connect to an Oracle database, but I guess that if the idea is to consider the System as a whole in the Context Diagram, I should "hide" that fact in the above diagram.
Where should I go on from here? I know I should "zoom" the System process to something more detailed. Maybe the next step would be to depict each one of the User Cases in a DataFlow diagram? Do I include repositories of data, already? For example, one for Users, other for Doctors and yet another for Administrators?
Thanks

Well, i was unable to find the ENTIRE answer here but i finally got what i was after. thanks very much for all of your help and patience.
i think i may have been having problems with using the int and Number types, upon closer inspection of my solution, i realised that Number was being used and not int. turns out number contains floating points and int doesn't. my numbers were probably rounding whenever i tried to fix this my self. for all i know, TDI's answer might have been spot on and the use of int for the padding might have accumulated rounded numbers.. Oh well, you learn something every day..
the correct code to constrain movie clips to a container movie clip (or sprite or whatever) in the fashion i was looking for is this:
```
var picContainer:PicContainer = new PicContainer();
picContainer.x = stage.stageWidth / 2 - picContainer.width / 2;
picContainer.y = stage.stageHeight / 2 - picContainer.height / 2;
addChild(picContainer);
var totalPics:int = 17;
var pic:Pic = new Pic(); //make an instance just to get its width
var xRange:Number = picContainer.width - pic.width;
var spacing:Number = xRange / (totalPics - 1);
//A little optimization: only need to calculate this number ONCE:
var yLoc:Number = picContainer.height / 2 - pic.height / 2;
for(var i:int = 0; i < totalPics; i++) {
pic = new Pic();
pic.x = i * spacing;
pic.y = yLoc;
picContainer.addChild(pic);
}
```
the logic is pretty simple, and i don't know why i couldn't get it my self, because i drew diagrams that say exactly this logic. however, i must not have put the numbers in the right places or i wouldn't have had to ask, would i ;P
as an added bonus (if anyone finds this thread looking for answers..)
you could also have the 'pic's fan out from the center point (but they'd still be in order of left to right) by using this code:
```
var picContainer:PicContainer = new PicContainer();
picContainer.x = stage.stageWidth / 2 - picContainer.width / 2;
picContainer.y = stage.stageHeight / 2 - picContainer.height / 2;
addChild(picContainer);
var totalPics:int = 5;
var pic:Pic = new Pic(); //make an instance just to get its width
var padding:Number = (picContainer.width - (pic.width * totalPics)) / (totalPics + 1);
for(var i:int = 0; i < totalPics; i++) {
pic = new Pic();
pic.x = padding + i * (pic.width + padding);
pic.y = picContainer.height / 2 - pic.height / 2;
picContainer.addChild(pic);
}
```
Try it out, these make for great thumbnail dock engines!
Well, there is some progress thanks to TDI but not a complete solution.
you see, the problem remains that the movie clips do not squash completely into the container, the last one or two are left sticking out.
```
example:
```
my revised code looks like this:
```
var newPicContainer:picContainer = new picContainer();
var newPic:pic;
var picwidth:int = 100;
var amountofpics:int = 22;
var i:int;
//add a container
addChild(newPicContainer);
//center our container
newPicContainer.x = (stage.stageWidth/2)- (newPicContainer.width/2);
newPicContainer.y = (stage.stageHeight/2)- (newPicContainer.height/2);
var totalpicwidth:int = picwidth*amountofpics;
var totalpadding:int = newPicContainer.width - totalpicwidth;
var paddingbetween:int = (totalpadding / amountofpics);
for (i = 0; i < amountofpics; ++i)
{
//make a new mc called newPic(and i's value) eg. newPic1
this['newPic' + i] = new pic();
this['newPic' + i].width = picwidth;
//add our pic to the container
newPicContainer.addChild(this['newPic' + i]);
//set the new pics X
if (i != 0)
{
// if i is not 0, set newpic(i)s x to the previous pic plus the previous pics width and add our dynamic padding
this['newPic' + i].x = this['newPic' + (i-1)].x + picwidth + paddingbetween;
}
else
{
this['newPic' + i].x = 0;
}
}
```
thanks again to anyone in advance!
Hello, First time posting here. I hope I'm not getting anything wrong . my problem is as follows:
I've got a pretty basic for loop that creates a 'thumbnail' and puts it next to the previous one (With a little padding) inside a containing movie clip.
```
var newPicContainer:picContainer = new picContainer();
var newPic:pic;
var amount:int = 9;
var i:int;
//Add our container
addChild(newPicContainer);
//center our container
newPicContainer.x = (stage.stageWidth/2)- (newPicContainer.width/2);
newPicContainer.y = (stage.stageHeight/2)- (newPicContainer.height/2);
for (i = 0; i < amount; ++i)
{
newPic = new pic();
newPicContainer.addChild(newPic);
//just so i know it's adding them..
trace(newPic.thisOne);
newPic.thisOne = i;
// set this one to its self (+5 for padding..) Times, the amount already placed.
newPic.x = (newPic.width+5) *i;
}
```
I'm wondering if there is some equation or 'magic math' that I can use to figure out what the length of the container is and have the 'thumbnails' be added relative to that number. basically squashing the thumbnails against each other to make them all fit inside..
something along the lines of:
```
newPic.x = (newPic.width *i) - stuff here to make it know not to go past the containing width;
```
I must admit i'm not too great with math and so this part of coding escapes me..
thanks to any takers in advance..

3,951,539 | 1 | null | null | 1 | 2,059 | I need an algorithm to intersect a (potentially non-convex) polygon with a rectangle. The rectangle will be parallel to the xy-plane, but the polygon could be any orientation.
Furthermore, I don't just need a true/false result, but also the exact points where the polygon intersects the rectangle, so that I can draw lines where the polygon overlaps the rectangle. For non-convex polygons, this could result in two or more lines of intersection.
This would be for a section-cut module that can slice a set of polygons and create a 2D "cut" where the shapes intersect the "plane," specified by a z-value.
I'm developing in Java, so if Java3(2)D has any built-in methods to help, that would be ideal.
Any help/pointers in the right direction would be greatly appreciated!

[http://www.w3schools.com/php/php_ajax_database.asp](http://www.w3schools.com/php/php_ajax_database.asp)
I created this database:
So now to recreate the example I just basically copied and pasted the code:
index.html
```
<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
{
document.getElementById("txtHint").innerHTML="";
return;

xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}

</head>

<select name="users" onchange="showUser(this.value)">

<option value="2">Manuel</option>
</select>
</form>
<br />
<div id="txtHint"><b>Person info will be listed here.</b></div>
</body>
</html>
```
and getuser.php
```
<?php
$q=$_GET["q"];
$con = mysql_connect('localhost', 'root', 'root');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("ajax_demo", $con);
$sql="SELECT * FROM user WHERE id = '".$q."'";
$result = mysql_query($sql);
echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
<th>Hometown</th>
<th>Job</th>

while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['FirstName'] . "</td>";
echo "<td>" . $row['LastName'] . "</td>";
echo "<td>" . $row['Age'] . "</td>";
echo "<td>" . $row['Hometown'] . "</td>";
echo "<td>" . $row['Job'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
```
Now the strange part is that when I go to index.html I can see the age, hometown and job but not Firstname and Lastname:
I realize this might be a very basic mistake but I cant find a workaround.
I am sorry I had to paste in so much code but I did not see any other way I could explain my problem and you could help me.
Thanks a lot in advance!

where `List` is just `list<double>` in STL.
`[0,1)` Theoretically bucket sort should be faster than quicksort for large size for it's O(n),but it fails as in the following graph.
I use `google-perftools` to profile it on a 10000000 double array. It reports as follow
It seems I should not use STL list,but I wonder why? Which does `std_List_node_base_M_hook` do? Should I write list class myself?
I have tried just leave the codes of putting in buckets and this explained that most time is used on building up buckets.
The following improvement is made:
- Use STL vector as buckets and reserve reasonable space for buckets
- Use two helper array to store the information used in building buckets,thus avoiding the use of linked list,as in following code
```
void bucketsort2(Array& A){
size_t numBuckets = ceil(A.size()/1000);
Array B(A.size());
IndexArray head(numBuckets+1,0),offset(numBuckets,0);//extra end of head is used to avoid checking of i == A.size()-1
for(size_t i=0;i!=A.size();i++){
head[int(numBuckets*A[i])+1]++;//Note the +1
}
for(size_t i=2;i<numBuckets;i++){//head[1] is right already
head[i] += head[i-1];
}
for(size_t i=0;i<A.size();i++){
size_t bucket_num = int(numBuckets*A[i]);
B[head[bucket_num]+offset[bucket_num]] = A[i];
offset[bucket_num]++;
}
A.swap(B);
//insertionsort(A);
for(size_t i=0;i<numBuckets;i++)
quicksort_range(A,head[i],head[i]+offset[i]);
}
```
The result in the following graph
where line start with list using list as buckets,start with vector using vector as buckets,start 2 using helper arrays.By default insertion sort is used at last and some use quick sort as the bucket size is big.
Note "list" and "list,only put in" ,"vector,reserve 8" and "vector,reserve 2" nearly overlap.
I will try small size with enough memory reserved.

## Background
I've got the following tree of objects:
```
Name Project
Users nil
John nil
Documents nil
Acme Project Acme Project <--- User selects a project
Proposal.doc Acme Project
12:32-12:33 Acme Project
13:11-13:33 Acme Project
...thousands more entries here...
```
- The user can assign a group to a project. All descendants get set to that project.- This locks up the main thread so I'm using NSOperations.- I'm using the Apple approved way of doing this, watching for `NSManagedObjectContextDidSaveNotification` and merging into the main context.
## The Problem
My saves have been failing with the following error:
`Failed to process pending changes before save. The context is still dirty after 100 attempts. Typically this recursive dirtying is caused by a bad validation method, -willSave, or notification handler.`
## What I've Tried
I've stripped all the complexities of my app away, and made the simplest project I could think of. And the error still occurs. I've tried:
- Setting the max number of operations on the queue to 1 or 10.- Calling `refreshObject:mergeChanges:` at several points in the NSOperation subclass.- Setting merge policies on the managed object context.- Build and Analyze. It comes up empty.
## My Question
How do I set relationships in an NSOperation without my app crashing? Surely this can't be a limitation of Core Data? Can it?
## The Code
Download my project: [http://synapticmishap.co.uk/CDMTTest1.zip](http://synapticmishap.co.uk/CDMTTest1.zip)
```
@implementation JGMainController
-(IBAction)startTest:(id)sender {
NSManagedObjectContext *imoc = [[NSApp delegate] managedObjectContext];
JGProject *newProject = [JGProject insertInManagedObjectContext:imoc];
[newProject setProjectName:@"Project"];
[imoc save];
// Make an Operation Queue
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[queue setMaxConcurrentOperationCount:1]; // Also crashes with a higher number here (unsurprisingly)
NSSet *allTrainingGroupsSet = [imoc fetchAllObjectsForEntityName:@"TrainingGroup"];
for(JGTrainingGroup *thisTrainingGroup in allTrainingGroupsSet) {
JGMakeRelationship *makeRelationshipOperation = [[JGMakeRelationship alloc] trainGroup:[thisTrainingGroup objectID] withProject:[newProject objectID]];
[queue addOperation:makeRelationshipOperation];
makeRelationshipOperation = nil;
}
}
// Called on app launch.
-(void)setupLotsOfTestData {
// Sets up 10000 groups and one project
}
@end
```
```

[imoc setUndoManager:nil];
[imoc setMergePolicy:NSMergeByPropertyStoreTrumpMergePolicy];
[[NSNotificationCenter defaultCenter] addObserver:self

}

[project addGroupsAssignedObject:trainingGroup];
[imoc save];
trainingGroupObjectIDs = nil;
projectObjectID = nil;
project = nil;
trainingGroup = nil;
}
-(void)mergeChanges:(NSNotification *)notification {
NSManagedObjectContext *mainContext = [appDelegate managedObjectContext];

}
@end
```
I've experimented some more, and even without the merge, the exception is still thrown. Just saving the managed object context in another thread after modifying a relationship is enough.
I have a shared persistent store coordinator with the app delegate. I've tried making a separate NSPersistentStoreCoordinator for the thread with the same URL as my data store, but Core Data complains.
I'd love to suggestions on how I can make a coordinator for the thread. The core data docs allude to there being a way of doing it, but I can't see how.

Right now the shadows are rendered as sprites which works fine for the most part. But we only want the shadows to hit the closest layer.
I've made an image that hopefully explains what we're trying to accomplish:
And here's what we have at the moment:
Basically we want the sprite to only render the part of the shadow that is at the same depth as the z-buffer.
We've played around with `glDepthFunc` and `GL_DEPTH_TEST` but nothing seems to work.
Here's how we're rendering the shadow sprite (subclassed CCSprite):
```
- (void)draw {
glDisable( GL_BLEND );
glEnable( GL_DEPTH_TEST );
glDepthFunc( GL_LESS );
glDepthMask( GL_FALSE );
[super draw];
glDepthMask( GL_TRUE );
glDisable( GL_DEPTH_TEST );
glEnable( GL_BLEND );
}
```
The `GL_BLEND` calls are only there so we can see the sprite at all times.
All sprites that aren't shadows use `glDepthMask( GL_TRUE )` and we're clearing the depth buffer on each frame.
Any help would be much appreciated!

3,955,095 | 1 | 3,957,042 | null | 6 | 5,257 | I am trying to use R to create a raster image from a matrix of data. However, I am getting some weird artifacts on the edge of my image.
The code I am using is as follows:
```
# From the example for rasterImage(). A 3 pixel by 5 pixel b/w checkerboard.
testImage <- as.raster(0:1, nrow=3, ncol=5)
testImage
[,1] [,2] [,3] [,4] [,5]
[1,] "#000000" "#FFFFFF" "#000000" "#FFFFFF" "#000000"
[2,] "#FFFFFF" "#000000" "#FFFFFF" "#000000" "#FFFFFF"
[3,] "#000000" "#FFFFFF" "#000000" "#FFFFFF" "#000000"
png('test.png', width=5, height=3, units='px')
# Just want the image, no margins, boarders or other fancy stuff.
par(mar = c(0,0,0,0) )
plot.new()
plotArea = par('fig')
rasterImage(testImage, plotArea[1], plotArea[3],
plotArea[2], plotArea[4], interpolate = FALSE )
dev.off()
```
This was executed in R 2.12.0 on OS X but I get the same output from R 2.11.0.
---
The output I am getting is the following (scaled from 5x3 to 150x90)
The pixels in the corners should be black which suggests some form of interpolation is occurring.
---
The output I am expecting to see is:
Any suggestions on why my code fails to faithfully produce a raster image from a matrix?
---
## Intended Use
This is for a package I am working on so I would like to stay within the R base packages if possible so as not to introduce additional dependencies. The package implements a graphics device, so if anyone has a C level solution picks up from the info passed by `GERaster()` in `src/main/engine.c` and creates a PNG using only the R libraries, I would be willing to give that a shot as well.
---
## Solutions for OS X
As pointed out by nico, the errant behavior is the result of antialiasing. The plot behaves as expected if `png()` is told to use an output method for which antialiasing can be disabled, such as Cairo graphics:
```
png('test.png', width=5, height=3, units='px', type='cairo', antialias=NULL)
```
On OS X the default backend for `png()` is Quartz, however `png(..., type='quartz')` currently ignores directives set by `quartz.options()`. Faithful output can be produced natively on OS X if the device is started by calling `quartz()` directly instead of using `png()`:
```
quartz(file='test.png', type='png', width=5, height=3, dpi=1, antialias=FALSE)
```
---
## Windows Thinks Differently
The following output is generated on Windows:
According to [an answer](http://r.789695.n4.nabble.com/Incorrect-positioning-of-raster-images-on-Windows-tp2999649p3001505.html) given by Paul Murrell (the benevolent dictator of R graphics
devices) on the R-help mailing list:
> This is a rounding (truncation) problem. Working on a fix.
This behavior on Windows should not be noticeable unless the raster image contains a very small number of pixels.

3,955,189 | 1 | 4,028,437 | null | 16 | 12,500 | so currently i'm trying to crop and resize a picture to fit it into a specific size without losing the ratio.
a small image to show what i mean:
i played a bit with [vocaro's categories](http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/) but they don't work with png's and have problems with gifs. also the image doesn't get cropped.
does anyone have a suggestion how to do this resizing the best way or probably have a link to an existing library/categorie/whatever?
thanks for all hints!
p.s.: does ios implement a "select a excerpt" so that i have the right ratio and only have to scale it?!

As can been seen from the screen grab, for some reason it is listing potential sources from a variety of referenced assemblies, but I can't see an obvious pattern as to why it is selecting these.
The 'GeneralDataSet' makes sense as that is a strongly-typed Dataset class, but I'm pretty sure most of the others are not, yet the design dialog still lists them.

3,958,851 | 1 | null | null | 6 | 1,728 | Suppose I've got a ton (a continuous stream) of requests to process, and each request has several stages. For example: "connecting to data source", "reading data from data source", "validating data", "processing data", "connecting to data sink", "writing result to data sink".
Which visualization methods or even tools fit well to visualize the behavior of such a system?
I'd like to be able to see which stages are taking a long time, and how the stages of different requests are aligned with respect to each other (for example, to see that the data source responds longer when accessed by too many requests at once).
If there were just a few dozen requests, I'd be OK with a few dozen individual colored timelines, but for a few thousand that doesn't fit well. I think I can get away with N colored timelines, where N is the "concurrency factor", but 1) perhaps there's something better, 2) perhaps there exist tools for this?
P.S. Shameless plug: Once I figure out the best way of visualization, I'll add it to my nifty tool called [timeplot](http://hackage.haskell.org/package/timeplot) ;)
P.P.S. Another shameless plug: I decided to write a separate tool: [splot](http://hackage.haskell.org/package/splot). Here's what it can do, based on a trivially simple log and an awk one-liner:
It's showing 160 cores of a cluster performing tasks fed to them by RabbitMQ. Blue is "fetching data", orange is "computing", white is "doing nothing". Several problems are immediately obvious from this diagram, which would be very hard to find by just looking at the logs.

3,959,122 | 1 | null | null | 23 | 34,332 | This is a memory stack (serves as a cache) that consist of nothing but a static ConcurrentHashMap (CHM).
All incoming HTTP request data are store in this ConcurrentHashMap. And there is a asynch scheduler process that takes the data from the same ConcurrentHashMap and remove the key.value after storing them into the Database.
This system runs fine and smooth but just discover under following criteria, the memory was fully utilized (2.5GB) and all CPU time was taken to perform GC:
-concurrent http hit of 1000/s
-maintain the same concurrent hit for a period of 15 minutes
The asynch process log the remaining size of the CHM everytime it writes to database. The CHM.size() maintain at around Min:300 to Max:3500
I thought there is a Memory Leak on this application. so i used Eclipse MAT to look at the Heap Dump. After running the Suspect Report, i got these comments from MAT:
> One instance of "org.apache.catalina.session.StandardManager" loaded by "org.apache.catalina.loader.StandardClassLoader @ 0x853f0280" occupies 2,135,429,456 (94.76%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Segment[]" loaded by "".
```
3,646,166 instances of java.util.concurrent.ConcurrentHashMap$Segment retain >= 2,135,429,456 bytes.
```
and
```
Length # Objects Shallow Heap Retained Heap
0 3,646,166 482,015,968 >= 2,135,429,456
```
The length 0 above i translate it as empty length record inside the CHM (each time i call CHM.remove() method). It is consistent to the number of record inside the database, 3,646,166 records was inside the database when this dump was created
: if i pause the stress test, the utilization in Heap Memory will gradually release down to 25MB.This takes about 30-45 minutes. i have re-simulate this application and the curves looks similar to the VisualVM Graph below:
Heres the questions:
1) Does this looks like a Memory Leak?
2) Each remove call `remove(Object key, Object value)` to remove a `<key:value>` from CHM, does that removed object get GC?
3) Is this something to do with the GC settings? i have added the following GC parameters but without help:
```
-XX:+UseParallelGC
-XX:+UseParallelOldGC
-XX:GCTimeRatio=19
-XX:+PrintGCTimeStamps
-XX:ParallelGCThreads=6
-verbose:gc
```
4) Any idea to resolve this is very much appreciated! :)
5) Could it be possible because all my reference are hard reference? My understanding is as long as the HTTP session is ended, all those variables that is not static are now available for GC.
Note I tried replace the CHM with ehcache 2.2.0, but i get the same OutOfMemoryException problem. i suppose ehcache is also using ConcurrentHashMap.

3,961,652 | 1 | 3,961,716 | null | 14 | 21,533 | i have content i need to display above my listview and below, so much that a scrollview would be great to use if you could use scrollviews and listviews together. Since thats not the best solution, i've been trying to do a couple of things to add footer content to my listview,
here the pic below shows what happens when i add a different type of row as the last row. I can't get my content to fill the width of the row
I have a couple of buttons that need to go in the footer. I'm using a custom adapter that extends BaseAdapter.
I have also tried using the addFooterView but i'm confused on how to use the addFooterView method if you are implementing your own adapter. Anyone have any simple examples of how to implement addFooterView on a custom adapter
or
is there a way i can get the row at this position (as seen in the picture ) to display better, here is the code i'm using to create this footer row
```
View v = getLayoutInflater().inflate(R.layout.item_listview_footer, null);
LinearLayout ll = (LinearLayout) v.findViewById(R.id.ll);
return ll; // return ll as convertView in getView function
```
edit:
here is the xml for my footer layout
```

3,962,531 | 1 | 4,023,937 | null | 0 | 395 | So I have two pictures of the weirdness that is occuring
As you can see in the picture above, the scroll bar on the right hand side is being cut off a little bit by the screen, and even when you scroll to the right, you don't get the bar back, it remains cut off.
Here is the other scenario:
Here, you can see that when I scroll down in this grid, the scroll bar kind of fits into the bottom of the grid and doesn't even go all the way down. You need to manually click into the grid and hit the down arrow to get the rest of the way down.
What could be causing both of these weird issues?
Edit:
Here is the code to generate the grid (Ext created through VB controls):
```
Dim VehicleOptionsGrid As New Akcelerant.Framework.WebControls.Grids.Grid
With VehicleOptionsGrid
.ID = "VehicleOptionsGrid"
.Title = "Vehicle Options"
.Toolbar.UseDefaultButtons = False
.Mode = Grids.Grid.GridMode.Control
.Panel.Border = False
.Panel.Style = "border-width:1px;margin-bottom:5px"
.Ref = "../../../../../VehicleOptionsGrid"
.Editable = True
With .Columns.Add("IsSelected", "Selection", Akcelerant.Framework.WebControls.Grids.Grid.ColumnDataType.Boolean)
.Renderer = "renderVehicleCheckbox"
End With
.Columns.Add("CollateralId", "").Hidden = True
.Columns.Add("OptionId", "OptionId").Hidden =True
.Columns.Add("OptionName", "Name").Width = 200
.GridHeight = 400
.DataBind()
ViewResponse.AddScript(.ToString(False))
ViewResponse.AddScript("VehicleOptionsGrid.grid.addListener('cellclick', changeOptionStatus);")
End With
```
Here is where we add the grid to the page:
```
With .AddPanel
With .AddPanel
.Title = ""
.Html = "Standard Options are preselected. Please select additional options as needed."
.Style = "padding-bottom:5px"
End With

.Title = "Vehicle Options"
.Frame = True
.Style = "padding-bottom:5px"

3,963,903 | 1 | null | null | 1 | 176 | I am trying to figure out a way to move two points, X and Y, independently of one another along the edges of an equilateral triangle with vertices A, B, and C. There are also some collision rules that need to be taken into account:
(1) If X is at a vertex, say vertex A, then Y cannot be on A or on the edges adjacent to it. i.e., Y can only be on vertices B or C or the edge BC.
(2) If X is on an edge, say AB, then Y cannot be on A, nor B, nor any of the edges adjacent to A and B. i.e., Y must be on vertex C
I have figured out how to move the two points along the triangle using a pair of sliders, but I can't figure out how to implement the collision rules. I tried using the Exclusions option for Slider but the results are not what I expect. I would prefer to drag the points along the triangle rather than using sliders, so if someone knows how to do that instead it would be helpful. Ideally, I would be able to
move the two points from a vertex to either one of the edges instead of coming to a stop at one of them. Here is my code so far.
`MyTriangle[t_] := Piecewise[{{{-1, 0} + (t/100) {1, Sqrt[3]}, 100 > t >= 0}, {{0, Sqrt[3]} + (t/100 - 1) {1, -Sqrt[3]}, 200 > t >= 100}, {{1, 0} + (t/100 - 2) {-2, 0}, 300 >= t >= 0}}] excluded[x_] := \[Piecewise] { {Range[0, 99]~Join~Range[201, 299], x == 0}, {Range[0, 199], x == 100}, {Range[101, 299], x == 200}, {Range[0, 199]~Join~Range[201, 299], 0 < x < 100}, {Range[1, 299], 100 < x < 200}, {Range[0, 99]~Join~Range[101, 299], 200 < x < 300} } {Dynamic[t], Dynamic[x]} {Slider[Dynamic[t], {0, 299, 1}, Exclusions -> Dynamic[excluded[x]]], Dynamic[t]} {Slider[Dynamic[x], {0, 299, 1}, Exclusions -> Dynamic[excluded[t]]], Dynamic[x]} Dynamic[Graphics[{PointSize[Large], Point[MyTriangle[t]], Point[MyTriangle[x]], Line[{{-1, 0}, {1, 0}, {0, Sqrt[3]}, {-1, 0}}]}, PlotRange -> {{-1.2, 4.2}, {-.2, 2}}]]`

What is a good, quick and clean way to check if the first line equals SUCCESS and then convert this into an associative array? I am able to do it, and it works, but I'm curious if there are better or cleaner ways of doing it cause what I end up with isn't always that nice. Notice that some of the keys don't have any value as well.
So, what I would like to end up with is essentially:
```
array(
'business' => '[email protected]',
'charset' => 'windows-1252',
'custom' => NULL,
'first_name' => Alice,
// And so on
);
```
The order doesn't matter.

# Benchmark results
Got curious to what I should choose here, so I benchmarked how I should do different parts. Had various ideas myself, got some from here and other places as well. When I had found the fastest I could manage, I created a benchmark and put it to the test against all of the answers so far. For the ones that had skipped the splitting or the checking for success I added an `explode` and a `strpos` check accordingly. I also added urldecode to all the solutions as well, except @dynamism who tackled that so nicely. Anyways, here are the results:
The benchmark was run using the [codebench](http://www.geertdedeckere.be/article/introducing-codebench) [Kohana 3](http://kohanaframework.org/) module. Here is the benchmark code:

From the output, it appears the size of the documents can have a drastic effect upon how long operations on those collections take.
Is there some documentation available that recommends what balance to strive for or some more "real" numbers around what document size will do to query times? Is this poor performance more a result of the driver and any serialization overhead? Has anyone else noticed this?

3,964,707 | 1 | 3,973,542 | null | 1 | 10,152 | I wrote a .NET application where memory usage is growing over time. As a test,
I set it up to download 800 * 5K (average) size files and doing XML transform and using DTComcontroller to generate manifest, inside 1 hour with an interval of 15 Minutes. During a period of about 5 hours, memory usage grows from 35M to about 70M.
Not sure if this is normal or not. I'm already forcing it by doing
```
GC.collection();
GC.WaitForPendingFinalizers();
```
at end of each working circle just to make sure the memory are released in a timely manner.
I already make sure close filehandle, clear stream or other resources after used it. And some objects are just using local references inside a function and I assume they will be discarded at the end of local function and go away with GC.collction().
Also Memory Profiler (ANTS) shows that there are no objects with my application's namespace left at the end of each of the working circle, and no new objects with source code available left as well. The new instances of objects created during each working circle are basically called RuntimeModule, RuntimeAssembly, and DeviceContext. Doesn't looks like I could do anything about it?
This is basically my first application which are suppose to run 24/7 and I really don't know much about memeory leak. More likely than not, there are still problems with memory usage in my application. I just don't know where to look at this stage.
Also, I don't know it's related or not, I am using .net Trace/debug for keep a log. Guess it worth trying to turn off the log to see the memory usage grow.
Update:
Dose it look like circle reference of sslstate and sslstream and also other Classes in the class Reference Explorer. Also not sure if that is a circle reference in ANTS generated graph, that means there is actually circle reference in my code somewhere?
I did a few changes by reusing the same object for XMLtransform and Manifest creation, and manually set each Object to null after finish used them in the end of working iteration. Now the memory are greatly reduced, still increase private memory usage as it is working, but much slowly.
I think for my particular case--create lots of objects inside a working circle, and every data is kept in a working thread. If I didn't explicitly release object references, let .NET GC doing that will lead to lots of memory used by the application as it is keep working most of the time, and GC may never get a chance to probably doing house keeping unless the application been manually closed, I have to do the object release much more manually.

I feel like it should be staring me in the eyes, and I've done a thousand factorial programs in C/Java etc.. but I can't see it here.
So it takes in user entry
if == 0 it breaks to done [brz]
if > 0 break to skip [brp]
neg used to negate value for abs value
Skip routine does the multiplication and decrememnts,
followed by more conditions to see if it needs to be called again or if the program is done.
I need essentially to find the loops in this program. Like I said, it's probably staring me in the face but it's a loosely asked question on the assigner's part..
EDIT to clarify:
The program doesn't take the factorial of one number, but rather multplies the factorial of each number entered.
So I could put in 3, -4, 2, 0 and the result will be 288.
(3*2*1)(4*3*2*1)(2*1)

```

3,964,835 | 1 | 3,964,961 | null | 7 | 3,078 | I'd love to stash some .json files on a CDN a la static.mydomain.com. Truth be told, static.mydomain.com is a CNAME in front of an Amazon S3 bucket.
I understand this violates the JavaScript security model. Is there an advised workaround or design? I've seen server-side stuff suggested like a PHP script to suck down data via cURL or file_gets_contents(), but that's a pretty lame approach. Is there any way to load JSON from a foreign server without getting too hacky?
===
UPDATE: Here's the line of thought that led me to believe it's a crossdomain issue for subdomains.
When I visit a page (e.g. static.mydomain.com/json/file.json) in Chrome, it displays as it would plaintext. When I visit the page in Firefox, it tries to get me to save the .json as a download.
I see a peculiar result in Firebug: A with no response body. 
I can't log the direct headers via browser; my Firefox HTTP header plugin doesn't log anything before the download is forced. However here are the headers when loaded via this jQuery snippit (worth noting, the alert below doesn't fire):
```
jQuery.get("https://static.mydomain.com/json/file.json",
function(data){
alert("Data: " + data);
}
);

Though the headers seem to me to be fine, to either a get, post, or anything else I can throw at this via jQuery. I see the same result when setting the content type to application/json, text/javascript and text/plain.
Can anyone explain this behavior? I figure I must be doing something wrong on the S3 side, but could it be crossdomain issues in JavaScript or can I rule out cross-subdomain issues?

The culprit seems to be the WebappClassLoader (in Tomcat, but it happens in Jetty too), which is kept in memory by references from a bunch of other objects. The following image shows that objects that refer to WebappClassLoader, and the things that refer to them, and so on.
One of the clingy objects seems to be an instance of `net.lag.logging.Level$INFO$`, to which a reference is stored in the static `known` array in `java.util.logging.Level`.
It appears that `java.util.logging.Level` keeps a static reference to all instances of itself. Bad, nasty `java.util.logging.Level`! Can I do anything about it? The java.util.logging framework is used by a third-party library, so I don't think I have the option of not using it.
