• Problem with bluetooth on android 2.1 (samsung spica i5700) where pairing works but connection does

  - by user319634

  I have a Samsung Spica i5700 which I already have updated to Android 2.1. I am using the phone with an application called Run.GPS (http://www.rungps.net). This application logs data such as GPS position, route, speed, bearing etc. It can also log heartrate provided the user has a Zephyr HxM bluetooth heart rate monitor ("HxM"), which I do have. I can pair the HxM to the phone through the standard bluetooth utility. I'm prompted for the PIN, which I enter and the device is shown as 'Paired but not connected'. In the Run.GPS application itself, I click on 'Connect Heartrate Monitor'. This times out after about 30 seconds and the error message is 'Could not connect to heartrate monitor. Please try other settings'. I used a friend's HTC Windows Mobile as a control device to see if the HxM works there. It does. The Run.GPS application automatically sets the baud rate (initially to 9600 IIRC, though the connection also worked with higher baud rates) and it is possible to choose between various COM ports as well as a .Net COM port. I did some testing on my Spica Android, to try to find out why the bluetooth connection doesn't work. Below are some log files that I connected over adb when I clicked on 'Connect to Heartrate Monitor' in the Run.GPS application. I would be interested in any tips (including if I'm posting to the wrong forum here ;-)) - whether or not it's possible to experiment with the baud rate in Android etc. I still don't know if the problem is with the Run.GPS application (I've posted already on the development forum there) or with Android 2.1. I checked out another application - Endomondo - which is also a sport tracking application which supports heartrate monitor only with the HxM. There, what looked like exactly the same error occurred - I clicked on 'Connect Zephyr HxM'. For a few seconds I was shown the 'Connecting...' status, but then it timed out into 'Not Connected'. I'm thus tending towards looking at Android for the problem. Here's the output of adb logcat while trying to connect ./adb logcat | grep Run.GPS D/WYNEX> (11551): Excute :: Run.GPS Trainer UV, (null) E/Run.GPS (11997): Cannot connect to BT device E/Run.GPS (11997): java.io.IOException: Service discovery failed E/Run.GPS (11997): at android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:374) E/Run.GPS (11997): at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:184) E/Run.GPS (11997): at ju.a(Unknown Source) E/Run.GPS (11997): at qk.j(Unknown Source) E/Run.GPS (11997): at fs.c(Unknown Source) E/Run.GPS (11997): at le.a(Unknown Source) E/Run.GPS (11997): at s.b(Unknown Source) E/Run.GPS (11997): at pb.a(Unknown Source) E/Run.GPS (11997): at as.a(Unknown Source) E/Run.GPS (11997): at am.b(Unknown Source) E/Run.GPS (11997): at gf.onTouchEvent(Unknown Source) E/Run.GPS (11997): at android.view.View.dispatchTouchEvent(View.java:3709) E/Run.GPS (11997): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) E/Run.GPS (11997): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEvent(PhoneWindow.java:1665) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneWindow.java:1107) E/Run.GPS (11997): at android.app.Activity.dispatchTouchEvent(Activity.java:2061) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1649) E/Run.GPS (11997): at android.view.ViewRoot.handleMessage(ViewRoot.java:1694) E/Run.GPS (11997): at android.os.Handler.dispatchMessage(Handler.java:99) E/Run.GPS (11997): at android.os.Looper.loop(Looper.java:123) E/Run.GPS (11997): at android.app.ActivityThread.main(ActivityThread.java:4363) E/Run.GPS (11997): at java.lang.reflect.Method.invokeNative(Native Method) E/Run.GPS (11997): at java.lang.reflect.Method.invoke(Method.java:521) E/Run.GPS (11997): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/Run.GPS (11997): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/Run.GPS (11997): at dalvik.system.NativeStart.main(Native Method) E/Run.GPS (11997): Cannot connect to BT device E/Run.GPS (11997): java.io.IOException: Service discovery failed Here's the output of dmesg while trying to connect the heartrate monitor <4>[74726.239833] select 11691 (.serviceModeApp), adj 15, size 3205, to kill <4>[74726.240741] select 11739 (com.wssnps), adj 15, size 3207, to kill <4>[74726.246870] select 11750 (id.partnersetup), adj 15, size 3219, to kill <4>[74726.253390] select 11857 (p.bluetoothicon), adj 15, size 3299, to kill <4>[74726.259879] select 13131 (ndroid.settings), adj 15, size 4586, to kill <4>[74726.266372] send sigkill to 13131 (ndroid.settings), adj 15, size 4586 <7>[74733.945097] [BT] GPIO_BT_WAKE = 1 <7>[74733.945121] [BT] wake_lock(bt_wake_lock) <7>[74733.951799] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74733.951822] [BT] wake_lock timeout = 5 sec <7>[74735.890196] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74736.150987] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74736.151009] [BT] wake_lock timeout = 5 sec <7>[74737.490185] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74740.073913] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74740.073948] [BT] wake_lock timeout = 5 sec <7>[74741.315336] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74743.249747] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74743.249768] [BT] wake_lock timeout = 5 sec <7>[74744.865099] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74745.154487] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74745.154509] [BT] wake_lock timeout = 5 sec <7>[74748.852534] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74749.156256] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74749.156278] [BT] wake_lock timeout = 5 sec <7>[74750.490018] [BT] GPIO_BT_HOST_WAKE = 0 <4>[74754.230424] select 11691 (.serviceModeApp), adj 15, size 3191, to kill <4>[74754.231326] select 11739 (com.wssnps), adj 15, size 3193, to kill <4>[74754.237473] select 11750 (id.partnersetup), adj 15, size 3205, to kill <4>[74754.243950] select 11857 (p.bluetoothicon), adj 15, size 3283, to kill <4>[74754.250452] select 13140 (com.svox.pico), adj 15, size 3465, to kill <4>[74754.256787] send sigkill to 13140 (com.svox.pico), adj 15, size 3465

• CUDA linking error - Visual Express 2008 - nvcc fatal due to (null) configuration file

  - by Josh

  Hi, I've been searching extensively for a possible solution to my error for the past 2 weeks. I have successfully installed the Cuda 64-bit compiler (tools) and SDK as well as the 64-bit version of Visual Studio Express 2008 and Windows 7 SDK with Framework 3.5. I'm using windows XP 64-bit. I have confirmed that VSE is able to compile in 64-bit as I have all of the 64-bit options available to me using the steps on the following website: (since Visual Express does not inherently include the 64-bit packages) http://jenshuebel.wordpress.com/2009/02/12/visual-c-2008-express-edition-and-64-bit-targets/ I have confirmed the 64-bit compile ability since the "x64" is available from the pull-down menu under "Tools-Options-VC++ Directories" and compiling in 64-bit does not result in the entire project being "skipped". I have included all the needed directories for 64-bit cuda tools, 64 SDK and Visual Express (\VC\bin\amd64). Here's the error message I receive when trying to compile in 64-bit: 1>------ Build started: Project: New, Configuration: Release x64 ------ 1>Compiling with CUDA Build Rule... 1>"C:\CUDA\bin64\nvcc.exe" -arch sm_10 -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin" -Xcompiler "/EHsc /W3 /nologo /O2 /Zi /MT " -maxrregcount=32 --compile -o "x64\Release\template.cu.obj" "c:\Documents and Settings\All Users\Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK\C\src\CUDA_Walkthrough_DeviceKernels\template.cu" 1>nvcc fatal : Visual Studio configuration file '(null)' could not be found for installation at 'C:/Program Files (x86)/Microsoft Visual Studio 9.0/VC/bin/../..' 1>Linking... 1>LINK : fatal error LNK1181: cannot open input file '.\x64\Release\template.cu.obj' 1>Build log was saved at "file://c:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\Projects\New\New\x64\Release\BuildLog.htm" 1>New - 1 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Here's the simple code I'm trying to compile/run in 64-bit: #include <stdlib.h> #include <stdio.h> #include <string.h> #include <math.h> #include <cuda.h> void mypause () { printf ( "Press [Enter] to continue . . ." ); fflush ( stdout ); getchar(); } __global__ void VecAdd1_Kernel(float* A, float* B, float* C, int N) { int i = blockDim.x*blockIdx.x+threadIdx.x; if (i<N) C[i] = A[i] + B[i]; //result should be a 16x1 array of 250s } __global__ void VecAdd2_Kernel(float* B, float* C, int N) { int i = blockDim.x*blockIdx.x+threadIdx.x; if (i<N) C[i] = C[i] + B[i]; //result should be a 16x1 array of 400s } int main() { int N = 16; float A[16];float B[16]; size_t size = N*sizeof(float); for(int i=0; i<N; i++) { A[i] = 100.0; B[i] = 150.0; } // Allocate input vectors h_A and h_B in host memory float* h_A = (float*)malloc(size); float* h_B = (float*)malloc(size); float* h_C = (float*)malloc(size); //Initialize Input Vectors memset(h_A,0,size);memset(h_B,0,size); h_A = A;h_B = B; printf("SUM = %f\n",A[1]+B[1]); //simple check for initialization //Allocate vectors in device memory float* d_A; cudaMalloc((void**)&d_A,size); float* d_B; cudaMalloc((void**)&d_B,size); float* d_C; cudaMalloc((void**)&d_C,size); //Copy vectors from host memory to device memory cudaMemcpy(d_A,h_A,size,cudaMemcpyHostToDevice); cudaMemcpy(d_B,h_B,size,cudaMemcpyHostToDevice); //Invoke kernel int threadsPerBlock = 256; int blocksPerGrid = (N+threadsPerBlock-1)/threadsPerBlock; VecAdd1(blocksPerGrid, threadsPerBlock,d_A,d_B,d_C,N); VecAdd2(blocksPerGrid, threadsPerBlock,d_B,d_C,N); //Copy results from device memory to host memory //h_C contains the result in host memory cudaMemcpy(h_C,d_C,size,cudaMemcpyDeviceToHost); for(int i=0; i<N; i++) //output result from the kernel "VecAdd" { printf("%f ", h_C[i] ); printf("\n"); } printf("\n"); cudaFree(d_A); cudaFree(d_B); cudaFree(d_C); free(h_A); free(h_B); free(h_C); mypause(); return 0; }

• Can not delete row from MySQL

  - by Drew

  Howdy all, I've got a table, which won't delete a row. Specifically, when I try to delete any row with a GEO_SHAPE_ID over 150000000 it simply does not disappear from the DB. I have tried: SQLyog to erase it. DELETE FROM TABLE WHERE GEO_SHAPE_ID = 150000042 (0 rows affected). UNLOCK TABLES then 2. As far as I am aware, bigint is a valid candidate for auto_increment. Anyone know what could be up? You gotta help us, Doc. We’ve tried nothin’ and we’re all out of ideas! DJS. PS. Here is the table construct and some sample data just for giggles.

• GetWindowPlacement/SetWindowPlacement not working in WinForms for high DPI

  - by RandomEngy

  I've got a legacy WinForms app and I want to save the window position and size across sessions. I've been using GetWindowPlacement and SetWindowPlacement during the FormClosing and Load events. The problem I'm getting is that at higher DPI settings (Such as Medium, size at 125%) the sizes keep inflating. I'll call SetWindowPlacement on it with a certain size, but when GetWindowPlacement is called, those numbers come back 25% bigger, even though the window was the same size all along. The same sort of problem exists when saving the size of a resizable element within the form. Now this works fine if I create a new WinForms project: The size stays stable even when running at the higher DPI. I'm guessing there's some legacy setting in the bowels of the project or some arcane Form setting that's messing it up, but I can't find out where. I've called IsProcessDPIAware on both projects and both are true. Does anyone know what might be causing this?

• UIToolbar above UIWebView inside UIScrollView

  - by Nick VanderPyle

  I'd like to display a toolbar above a UIWebView but hide the toolbar until the person "pulls it down". The same functionality can be seen in Safari on the iPhone. When the page loads, the toolbar containing the address is hidden. You must pull it down. In Safari it's possible to scroll up and eventually see the toolbar or scroll down through the page contents. I've tried placing a UIToolbar and UIWebView inside a UIScrollView but it didn't work. I've tried setting the UIScrollView to the size of the toolbar and webview combined, but that didn't work. - (void)viewDidLoad{ CGSize size = CGSizeMake(webView.frame.size.width, toolBar.frame.size.height + webView.frame.size.height); [scrollView setContentSize:size]; } How should I go about doing this?

• How to tell rails to use non-default ruby?

  - by Hamish Downer

  I need two different versions of ruby on a server. The packaged ruby for the packaged puppet to work, and a compiled ruby for a rails web app to work. So basically I want the default ruby to be the ruby from the package, and for rails to use the compiled ruby (in /usr/local/bin/ and /usr/local/lib/ ) I've found references to setting the RUBYPATH and RUBYLIB environment variables, but I'm confused as to where to set them. In .bashrc, .profile, in the apache config somewhere?

• How to get rid of previous reflection when reflecting a UIImageView (with changing pictures)?

  - by epale

  Hi everyone, I have managed to use the reflection sample app from apple to create a reflection from a UIImageView. But the problem is that when I change the picture inside the UIImageView, the reflection from the previous displayed picture remains on the screen. The new reflection on the next picture then overlaps the previous reflection. How do I ensure that the previous reflection is removed when I change to the next picture? Thank you so much. I hope my question is not too basic. Here is the codes which i used so far: //reflection self.view.autoresizesSubviews = YES; self.view.userInteractionEnabled = YES; // create the reflection view CGRect reflectionRect = currentView.frame; // the reflection is a fraction of the size of the view being reflected reflectionRect.size.height = reflectionRect.size.height * kDefaultReflectionFraction; // and is offset to be at the bottom of the view being reflected reflectionRect = CGRectOffset(reflectionRect, 0, currentView.frame.size.height); reflectionView = [[UIImageView alloc] initWithFrame:reflectionRect]; // determine the size of the reflection to create NSUInteger reflectionHeight = currentView.bounds.size.height * kDefaultReflectionFraction; // create the reflection image, assign it to the UIImageView and add the image view to the containerView reflectionView.image = [self reflectedImage:currentView withHeight:reflectionHeight]; reflectionView.alpha = kDefaultReflectionOpacity; [self.view addSubview:reflectionView]; //reflection */ Then the codes below are used to form the reflection: CGImageRef CreateGradientImage(int pixelsWide, int pixelsHigh) { CGImageRef theCGImage = NULL; // gradient is always black-white and the mask must be in the gray colorspace CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray(); // create the bitmap context CGContextRef gradientBitmapContext = CGBitmapContextCreate(nil, pixelsWide, pixelsHigh, 8, 0, colorSpace, kCGImageAlphaNone); // define the start and end grayscale values (with the alpha, even though // our bitmap context doesn't support alpha the gradient requires it) CGFloat colors[] = {0.0, 1.0, 1.0, 1.0}; // create the CGGradient and then release the gray color space CGGradientRef grayScaleGradient = CGGradientCreateWithColorComponents(colorSpace, colors, NULL, 2); CGColorSpaceRelease(colorSpace); // create the start and end points for the gradient vector (straight down) CGPoint gradientStartPoint = CGPointZero; CGPoint gradientEndPoint = CGPointMake(0, pixelsHigh); // draw the gradient into the gray bitmap context CGContextDrawLinearGradient(gradientBitmapContext, grayScaleGradient, gradientStartPoint, gradientEndPoint, kCGGradientDrawsAfterEndLocation); CGGradientRelease(grayScaleGradient); // convert the context into a CGImageRef and release the context theCGImage = CGBitmapContextCreateImage(gradientBitmapContext); CGContextRelease(gradientBitmapContext); // return the imageref containing the gradient return theCGImage; } CGContextRef MyCreateBitmapContext(int pixelsWide, int pixelsHigh) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // create the bitmap context CGContextRef bitmapContext = CGBitmapContextCreate (nil, pixelsWide, pixelsHigh, 8, 0, colorSpace, // this will give us an optimal BGRA format for the device: (kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst)); CGColorSpaceRelease(colorSpace); return bitmapContext; } (UIImage *)reflectedImage:(UIImageView *)fromImage withHeight:(NSUInteger)height { if (!height) return nil; // create a bitmap graphics context the size of the image CGContextRef mainViewContentContext = MyCreateBitmapContext(fromImage.bounds.size.width, height); // offset the context - // This is necessary because, by default, the layer created by a view for caching its content is flipped. // But when you actually access the layer content and have it rendered it is inverted. Since we're only creating // a context the size of our reflection view (a fraction of the size of the main view) we have to translate the // context the delta in size, and render it. // CGFloat translateVertical= fromImage.bounds.size.height - height; CGContextTranslateCTM(mainViewContentContext, 0, -translateVertical); // render the layer into the bitmap context CALayer *layer = fromImage.layer; [layer renderInContext:mainViewContentContext]; // create CGImageRef of the main view bitmap content, and then release that bitmap context CGImageRef mainViewContentBitmapContext = CGBitmapContextCreateImage(mainViewContentContext); CGContextRelease(mainViewContentContext); // create a 2 bit CGImage containing a gradient that will be used for masking the // main view content to create the 'fade' of the reflection. The CGImageCreateWithMask // function will stretch the bitmap image as required, so we can create a 1 pixel wide gradient CGImageRef gradientMaskImage = CreateGradientImage(1, height); // create an image by masking the bitmap of the mainView content with the gradient view // then release the pre-masked content bitmap and the gradient bitmap CGImageRef reflectionImage = CGImageCreateWithMask(mainViewContentBitmapContext, gradientMaskImage); CGImageRelease(mainViewContentBitmapContext); CGImageRelease(gradientMaskImage); // convert the finished reflection image to a UIImage UIImage *theImage = [UIImage imageWithCGImage:reflectionImage]; // image is retained by the property setting above, so we can release the original CGImageRelease(reflectionImage); return theImage; } */

• How to create default subfolders using procmail with Maildir (and postfix) that work with MUA's?

  - by user973917

  I have a procmail setup and want to have a Spam folder that works with MUA's. I found this tutorial http://www.cyberciti.biz/faq/how-do-i-move-spam-mail-to-spam-folder/ but it doesn't work as expected. I want to be able to open a mail client and see the Spam folder to deduce whether or not the messages are actually spam. How do I do this having a "default" Spam folder setup that can be read/accessed from mail clients like Thunderbird and Roundcube?

• Why is the size of a directory always 4096 bytes in unix?

  I am sure a directory file has much less information than 4096 bytes. I know the sector size is 4096 bytes. But normal files smaller than that do exist. Why does Unix reserve 4096 bytes for each folder?

• Swiping Images with Page Control in Iphone

  - by lakesh

  I am trying to make practice app where i can scroll images with page control. I am able to scroll images and able to include the page control. But the problem i face is i am not able to interlink the two. Meaning to say when I scroll the images, the page control is not affected and when i change the page control, the scrolling of the images is unaffected. I have referred to this: http://www.iosdevnotes.com/2011/03/uiscrollview-paging/ for the scrolling with page control. Viewcontroller.h #import <UIKit/UIKit.h> @interface ViewController : UIViewController <UIScrollViewDelegate>{ UIScrollView *scrollView; UIPageControl *pageControl; BOOL pageControlBeingUsed; } @property (nonatomic, retain) IBOutlet UIScrollView *scrollView; @property (nonatomic, retain) IBOutlet UIPageControl *pageControl; - (IBAction)changePage; @end Viewcontroller.m #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize scrollView,pageControl; - (void)viewDidLoad { [super viewDidLoad]; NSArray *images = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"1.jpeg"],[UIImage imageNamed:@"2.jpeg"],[UIImage imageNamed:@"3.jpeg" ], nil]; self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * images.count, self.scrollView.frame.size.height); for (int i = 0; i < images.count; i++) { CGRect frame; frame.origin.x = self.scrollView.frame.size.width * i; frame.origin.y = 0; frame.size = self.scrollView.frame.size; UIImageView* imgView = [[UIImageView alloc] init]; imgView.image = [images objectAtIndex:i]; imgView.frame = frame; [scrollView addSubview:imgView]; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; self.scrollView = nil; } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Update the page when more than 50% of the previous/next page is visible CGFloat pageWidth = self.scrollView.frame.size.width; int page = floor((self.scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; self.pageControl.currentPage = page; } - (IBAction)changePage{ // update the scroll view to the appropriate page CGRect frame; frame.origin.x = self.scrollView.frame.size.width * self.pageControl.currentPage; frame.origin.y = 0; frame.size = self.scrollView.frame.size; [self.scrollView scrollRectToVisible:frame animated:YES]; pageControlBeingUsed = YES; } - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView { pageControlBeingUsed = NO; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { pageControlBeingUsed = NO; } @end Need some guidance on this...

• Averaging initial values for rolling series

  - by Dave Jarvis

  Question Given a maximum sliding window size of 40 (i.e., the set of numbers in the list cannot exceed 40), what is the calculation to ensure a smooth averaging transition as the set size grows from 1 to 40? Problem Description Creating a trend line for a set of data has skewed initial values. The complete set of values is unknown at runtime: they are provided one at a time. It seems like a reverse-weighted average is required so that the initial values are averaged differently. In the image below the leftmost data for the trend line are incorrectly averaged. Current Solution Created a new type of ArrayList subclass that calculates the appropriate values and ensures its size never goes beyond the bounds of the sliding window: /** * A list of Double values that has a maximum capacity enforced by a sliding * window. Can calculate the average of its values. */ public class AveragingList extends ArrayList<Double> { private float slidingWindowSize = 0.0f; /** * The initial capacity is used for the sliding window size. * @param slidingWindowSize */ public AveragingList( int slidingWindowSize ) { super( slidingWindowSize ); setSlidingWindowSize( ( float )slidingWindowSize ); } public boolean add( Double d ) { boolean result = super.add( d ); // Prevent the list from exceeding the maximum sliding window size. // if( size() > getSlidingWindowSize() ) { remove( 0 ); } return result; } /** * Calculate the average. * * @return The average of the values stored in this list. */ public double average() { double result = 0.0; int size = size(); for( Double d: this ) { result += d.doubleValue(); } return (double)result / (double)size; } /** * Changes the maximum number of numbers stored in this list. * * @param slidingWindowSize New maximum number of values to remember. */ public void setSlidingWindowSize( float slidingWindowSize ) { this.slidingWindowSize = slidingWindowSize; } /** * Returns the number used to determine the maximum values this list can * store before it removes the first entry upon adding another value. * @return The maximum number of numbers stored in this list. */ public float getSlidingWindowSize() { return slidingWindowSize; } } Resulting Image Example Input The data comes into the function one value at a time. For example, data points (Data) and calculated averages (Avg) typically look as follows: Data: 17.0 Avg : 17.0 Data: 17.0 Avg : 17.0 Data: 5.0 Avg : 13.0 Data: 5.0 Avg : 11.0  Related Sites The following pages describe moving averages, but typically when all (or sufficient) data is known: http://www.cs.princeton.edu/introcs/15inout/MovingAverage.java.html http://stackoverflow.com/questions/2161815/r-zoo-series-sliding-window-calculation http://taragana.blogspot.com/ http://www.dreamincode.net/forums/index.php?showtopic=92508 http://blogs.sun.com/nickstephen/entry/dtrace_and_moving_rolling_averages
