• Using mod_rewrite for a RESTful api

  - by razass

  Say the user is making a request to the following url: "http://api.example.com/houses/123/abc" That request needs to map to "/webroot/controls/houses.php" and send "123" and "abc" to houses.php as variables without modifying the http headers or body. "houses" could theoretically be anything; cars, boats; and map to the corresponding php file... cars.php, boats.php respectively with a fallback to index.php if there is no match. There can be any number of variables after "houses" ie) "http://api.example.com/houses/1234/abc/zxy/987" I think I already have ALL requests being sent to webroot using: <IfModule mod_reqrite.c> RewriteEngine on RewriteRule ^$ webroot/ [L] RewriteRule (.*) webroot/$1 [L] </IfModule> But now I am at a loss as to how to take the next step as mentioned above. Any help is appreciated, even if you feel that I am taking the wrong approach. Thanks in advance!

• Unique identifier for an email

  - by Skywalker

  I am writing a C# application which allows users to store emails in a MS SQL Server database. Many times, multiple users will be copied on an email from a customer. If they all try to add the same email to the database, I want to make sure that the email is only added once. MD5 springs to mind as a way to do this. I don't need to worry about malicious tampering, only to make sure that the same email will map to the same hash and that no two emails with different content will map to the same hash. My question really boils down to how one would combine multiple fields into one MD5 (or other) hash value. Some of these fields will have a single value per email (e.g. subject, body, sender email address) while others will have multiple values (varying numbers of attachments, recipients). I want to develop a way of uniquely identifying an email that will be platform and language independent (not based on serialization). Any advice?

• Maintain aspect ratio on browser window resize?

  - by Anthony

  I have a simple page with images, and when the user clicks the image, it opens up a new browser window with the image filling the area. I have the css set on the new window so that the image height and width are both 100% (and overflow is set to hidden) so that the window can be resized. But what I need is for the window to maintain aspect ratio if the user resizes it. Right now, I'm stuck because I'm not getting how the event works, but I think I'm making this harder than it needs to be. Right now I have: $(function(){ $(window).resize(function() { var height = $(this).attr("innerHeight"); var width = $(this).attr("innerWidth"); if(height/width != .75){ window.resizeTo(width,width*.75); } }); }); Before I added the conditional, the window would immediately start shrinking (apparently opening a new window fires the resize event). Adding the conditional preventing this from happening when the window opens, but any resizing starts the shrinking again. Is it just because the height and width are never exactly the right ratio (should I manually set the width to a round number ever time) or is there something else I'm doing wrong? Or is there some other way to get what I'm after that's more straightforward?

• Reinterpret a CGImageRef using PyObjC in Python

  - by Michael Rondinelli

  Hi, I'm doing something that's a little complicated to sum up in the title, so please bear with me. I'm writing a Python module that provides an interface to my C++ library, which provides some specialized image manipulation functionality. It would be most convenient to be able to access image buffers as CGImageRefs from Python, so they could be manipulated further using Quartz (using PyObjC, which works well). So I have a C++ function that provides a CGImageRef representation from my own image buffers, like this: CGImageRef CreateCGImageRefForImageBuffer(shared_ptr<ImageBuffer> buffer); I'm using Boost::Python to create my Python bridge. What is the easiest way for me to export this function so that I can use the CGImageRef from Python? Problems: The CGImageRef type can't be exported directly because it is a pointer to an undefined struct. So I could make a wrapper function that wraps it in a PyCObject or something to get it to send the pointer to Python. But then how do I "cast" this object to a CGImageRef from Python? Is there a better way to go about this?

• Django Upload form to S3 img and form validation

  - by citadelgrad

  I'm fairly new to both Django and Python. This is my first time using forms and upload files with django.

• UIScrollView ImageView with pins on top

  - by Koppo

  To all, I have a UIScrollView which has a UIImageView. I want to show pins on this imageView. When I add pins as subviews of the ImageView everything is great except for when you zoom the scale transform happens on the pins also. I don't want this behavior and want my pins to stay the same. So I choose to add the Pins to another view which sits on top of the ImageView and is also a subview of the UIScrollView. The idea here if you will imagine is to have a layer which hovers over the map and won't scale yet show pins over where I plot them. The pin when added to the layer view don't cale if the ImageView scales. However the issue then bceomes the position of the pins doesn't match the original origin x/y as the ImageView has had a scale transform. Basically this is a custom map of a place with Pins. I am trying to have the Pins float over and not zoom in and out over my ImageView yet remember where I placed them when the zoom happens. Some code scrollView = [[UIScrollView alloc] initWithFrame:viewRect]; scrollView.delegate = self; scrollView.pagingEnabled = NO; scrollView.scrollsToTop = NO; [scrollView setBackgroundColor:[UIColor clearColor]]; scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView.bounces = YES; scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight; scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; imageViewMap = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; imageViewMap.userInteractionEnabled = YES; viewRect = CGRectMake(0,0,imageViewMap.image.size.width,imageViewMap.image.size.height); //viewRect = CGRectMake(0,0,2976,3928); [scrollView addSubview:imageViewMap]; [scrollView setContentSize:CGSizeMake(viewRect.size.width, viewRect.size.height)]; iconsView = [[UIView alloc] initWithFrame:imageViewMap.frame]; [scrollView addSubview:iconsView]; Code to add Pin later on some event. [iconsView addSubview:pinIcon]; I am stuck in trying tp figure out how to to get my pins to hover on the map without moving when the scale happens. Thanks

• jQuery hover DIV- stay active if they hover over the DIV itself

  - by Lock

  I have a DIV that opens up when an image is hovered. When the user leaves the image, the div disappears after a timeout. How can I make it so that the DIV will stay active if the user was to hover over the DIV itself? So the DIV will stay active as long as the user is on the image or the DIV itself? I am using the following: $(document).ready(function() { $(".hover").hover( function(e){ if ( $("#status").is(":hidden")) { var ref = $(this).attr("wsref"); var url = "https://site/_ref/shop/_base/order_status.php?action=getstatus&ref="+ref+"&sid="+Math.random(); $("#status").show(); var height = $(".status").height(); var width = $(".status").width(); leftVal = e.pageX - width -10 + "px"; topVal = e.pageY - height -10 + "px"; $("#status").css({left:leftVal,top:topVal}); $("#status").html("<div id='loading'></div>").load(url); } }, function() { if ( $("#status").is(':visible')) { setTimeout('$("#status").hide()',0); } }); }); HTML <a href="#"><img class="hover" title="Order Received" name="Order Received" src="https://site/_ref/images/cart.png" wsref="002731"/></a>

• QT- QImage and multi-threading problem.

  - by umanga

  Greetings all, Please refer to image at : http://i48.tinypic.com/316qb78.jpg We are developing an application to extract cell edges from MRC images from electron microscope. MRC file format stores volumetric pixel data (http://en.wikipedia.org/wiki/Voxel) and we simply use 3D char array(char***) to load and store data (gray scale values) from a MRC file. As shown in the image,there are 3 viewers to display XY,YZ and ZX planes respectively. Scrollbars on the top of the viewers use to change the image slice along an axis. Here is the steps we do when user changes the scrollbar position. 1) get the new scrollbar value.(this is the selected slice) 2) for the relavant plane (YZ,XY or ZX), generate (char* slice;) array for the selected slice by reading 3D char array (char***) 3) Create a new QImage* (Format_RGB888) and set pixel values by reading 'slice' (using img-setPixel(x,y,c);) 4) This new QImage* is painted in the paintEvent() method. We are going to execute "edge-detection" process in a seperate thread since it is an intensive process.During this process we need to draw detected curve (set of pixels) on top of above QImage*.(as a layer).This means we need to call drawPoint() methods outside the QT thread. Is it the best wayto use QImage for this case? What is the best way to execute QT drawing methods from another thread? thanks in advance,

• Updating / refreshing a live geojson layer | JSON & JS Variable

  - by Ozaki

  TLDR I am trying to get my geoJSON layer to update, currently it will 1. Create the vector mark, 2. Remove the vector mark, 3. Set the JS variable for lat and lon, 4. Unset the variable??? :S Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var latitude = 0.0; // as 0.0 it will draw the point in. var longitude = 0.0; // as 0.0 it will draw the point in. //var longitude = getlongitude; where getlongitude = JSON string of longitude. var point = new OpenLayers.Geometry.Point(longitude, latitude); pointFeature = new OpenLayers.Feature.Vector(point, null, style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[2].destroyFeatures(); map.layers[2].addFeatures(pointFeature); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing? Edit1 It now removes the feature (was map.layers[1]) previously... But will not add the new feature.. Edit2 I managed to get it to redraw a point but not with live data. It should draw the point at what (latitude) & (longitude) are equal to. I am trying to set latitude & longitude to some JSON string but every time straight after it sets the variable it changes it back to "undefined" as soon as it passes the line after var latitude? (using firebug & firequery to debug)

• Modify coverflow component ,add backview ?

  - by hib

  Hi all , I am developing an iPhone application in which I needs to implement a Coverflow component. I got a good library from here It is working nicely . Now I want to show a different back view with 6 buttons when a user double taps on the image in the coverflow . For that the tapkulibrary author has implemented a delegate method called which is : - (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasDoubleTapped:(int)index{ TKCoverView *cover = [coverflowView coverAtIndex:index]; //if(cover == nil) return; // [UIView beginAnimations:nil context:nil]; // [UIView setAnimationDuration:1]; // [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:cover cache:YES]; // [UIView commitAnimations]; *********************MY BACK View ******************************* UIView *c; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"TestMine" owner:nil options:nil]; c = [array objectAtIndex:0]; [cover addSubview:c]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:cover cache:YES]; [UIView setAnimationDuration:1.0]; CGAffineTransform transform = CGAffineTransformMakeScale(1.2, 1.2); cover.transform = transform; [UIView commitAnimations]; NSLog(@"Index: %d",index); } I am not much aware about the drawing code used in this example my back view is not working perfectly . So can anyone modify me this method or code to push my back view when double tapping the image and again double tapping shows the real image again . I need help .

• science.js’s loess() output is identical to input

  - by user3710111

  Rendered project available here. The line is supposed to be a trend line (as rendered with LOESS), but it merely follows each data point instead. I am no stats wonk, so maybe it makes sense that a LOESS function’s output would match the input as seen in the above example, but it strikes me as being wrong. Here is the relevant bit of code: var loess = science.stats.loess().bandwidth(.2); var xVal = data.map(function(d) { return d.date; }); var yVal = data.map(function(d) { return d.A; }); var loessData = loess([xVal], [yVal])[0]; console.log(yVal); console.log(loessData);

• Listing all shared memory segments used by a process on AIX5.3+

  - by Frank Meerkötter

  I would like to find all shared memory segments used by a given process. I am especially interested in figuring out the shmid so i can use it in calls to shmctl(). On Solaris i would just read /proc/$PID/map to figure out that information (field pr_shmid). The contents of that file are defined by struct prmap_t in sys/procfs. AIX also has a /proc/$PID/map file. There is also a struct prmap but unfortunately it is missing the pr_shmid field. Any ideas how i can achieve this on AIX5.3+?

• UIImagePickerController shows last picture taken instead of camera input

  - by jules

  I'm having a strange behaviour within my app. For taking pictures i'm using the following pretty standard code for displaying the UIImagePickerController: UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.allowsEditing = NO; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentViewController:picker animated:YES completion:nil]; It works perfectly fine the first time I tap the button which calls this action. The strange behaviour starts when I tap that button again. The UIImagePickerController starts again BUT it doesnt show the input from the camera anymore. It shows the last picture I've taken. More Details of this state: Tapping on the image shows the yellow square of the auto focus. (which it actually uses to focus the camera correctly) When I tap on the ImageCapture button - the correct image is taken and presented on the screen. If I take a picture and press 'Retake' the regular camera image is presented as input. More weirdness: It has nothing to do with the iPad I'm using. Creating a new example app which only has button which calls the code from above everything works perfectly fine. I assume it has something to do with the configuration of the app. Therefore I checked everything but could not find any differences which may cause this issue. Thanks in advance for any advice! Update: I do implement the UIImagePickerControllerDelegate in order to dismiss the UIImagePickerController.

• R heatmaps - non-text labels?

  - by Carl

  I am making a heatmap plot; currently the axes are labeled by index number. However, the index number corresponds to a series of 1/0s, which my group typically represents with a row of filled(1) or unfilled(0) boxes (think chessboard, though not strictly alternating colors). I'd like to use that representation instead of the index numbers. Any suggestions? I've considered simply making the labels as a plot, and positioning that adjacent to the heatmap, but I'm not finding a convenient way to do that either. I will also appreciate answers that are more generically applicable. edit - current code: map <- data.matrix(read.csv("./heatmap.out", header=F, sep=" ")) # ...some clean-up p<-heatmap(map, Rowv=NA, Colv=NA, col=grey(10:0 / 10)) this simply labels the heatmap rows/cols by index number. heatmap.out is raw numeric data.

• How to save a picture to a file?

  - by Peter vdL

  I'm trying to use a standard Intent that will take a picture, then allow approval or retake. Then I want to save the picture into a file. Here's the Intent I am using: Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); startActivityForResult( intent, 22 ); The docs at http://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE say "The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT." I don't pass extra output, I hope to get a Bitmap object in the extra field of the Intent passed into onActivityResult() (for this request). So where/how do you extract it? Intent has a getExtras(), but that returns a Bundle, and Bundle wants a key string to give you something back. What do you invoke on the Intent to extract the bitmap?

• Passing dynamic CSS to jQuery.animate

  - by harpo

  The documentation of jQuery.animate states that The only required parameter is a map of CSS properties. This map is similar to the one that can be sent to the .css() method, except that the range of properties is more restrictive. So, why does this work $('#con div').css( { top : function(i) { console.log(i); return (i * 500) + 'px'; } } ); and this doesn't? $('#con div').animate( { top : function(i) { console.log(i); return (i * 500) + 'px'; } } ); The console shows that the function is being evaluated for css, but not for animate. Am I missing something? By the way, I'm using 1.4.2.

• iPhone - User Defaults and UIImages

  - by Staros

  Hello, I've been developing an iPhone app for the last few months. Recently I wanted to up performance and cache a few of the images that are used in the UI. The images are downloaded randomly from the web by the user so I can't add specific images to the project. I'm also already using NSUserDefaults to save other info within the app. So now I'm attempting to save a dictionary of UIImages to my NSUserDefaults object and get... -[UIImage encodeWithCoder:]: unrecognized selector sent to instance I then decided to subclass UIImage with a class named UISaveableImage and implement NSCoding. So now I'm at... @implementation UISaveableImage -(void)encodeWithCoder:(NSCoder *)encoder { [encoder encodeObject:super forKey:@"image"]; } -(id)initWithCoder:(NSCoder *)decoder { if (self=[super init]){ super = [decoder decodeObjectForKey:@"image"]; } return self; } @end which isn't any better than where I started. If I was able to convert an UIImage to NSData I would be good, but all I can find are function like UIImagePNGRepresentation which require me to know what type of image this was. Something that UIImage doesn't allow me to do. Thoughts? I feel like I might have wandered down the wrong path...

• WPF DataTemplate - Overlay

  - by David Ward

  I have a class that I need to provide the datatemplate for. Currently I have two datatemplates, one for when Enabled == true and one for when Enabled == false. The datatemplate for the class is actually the one below which changes the template used based on a trigger: <DataTemplate x:Key="ActionNodeTemplateSelector"> <ContentPresenter Content="{Binding}" Name="cp" /> <DataTemplate.Triggers> <DataTrigger Binding="{Binding Enabled}" Value="True"> <Setter TargetName="cp" Property="ContentTemplate" Value="{StaticResource ActionNodeTemplate}" /> </DataTrigger> <DataTrigger Binding="{Binding Enabled}" Value="False"> <Setter TargetName="cp" Property="ContentTemplate" Value="{StaticResource ActionNodeDisabledTemplate}" /> </DataTrigger> </DataTemplate.Triggers> </DataTemplate> This all works well. However, now I want to also display an image overlay if the "Completed" property is true and a different image if it is incomplete. I could easily carry on using my approach to trigger on the Completed property as well but this would double the number of templates and feels wrong. Is there a way that I could have a trigger on my DataTemplate that will allow me to overlay the correct image over the existing template which is based on the Enabled property?

I am modifying the address field like this: RichTextField addrField = new RichTextField(address) { public int getPreferredWidth() { return 200; } protected void layout(int maxWidth,int maxHeight) { super.layout(getPreferredWidth(),maxHeight); setExtent(getPreferredWidth(), getHeight()); } }; The results look like this: ----------------------------- | address is ve| ***********| | state, zip | ** IMAGE **| | | ***********| ----------------------------- where clearly the address is just going under the image. Both horizontal fields are static 200 pixels wide. It's not like the system wouldn't know where to wrap the address. However, I have heard it is not easy to do this and is not done automatically. I have had no success finding a direct answer online. I have found people saying you need to do it in a custom layout manager, some refer to the RichTextField API, which is of no use. But nobody actually mentions how to do it. I understand that I may need to read character by character and set where the line breaks should happen. What I don't know is how exactly to do any of this. You can't just count characters and assume each is worth 5 pixels, and you shouldn't have to. Surely there must be some way to achieve this in a way that makes sense. Any suggestions?

• How to get the coordinate of Gridlayout

  - by Jessy

  Hi, I set my JPanel to GridLayout (6,6), with dimension (600,600) Each cell of the grid will display one pictures with different widths and heights. The picture first add to a JLabel, and the JLabel then added to the cells. How can retrieved the coordinate of the pictures in the cells and not the coordinate of cells? So far the out give these coordinate which equal height and width even on screen the pictures showed in different sizes. e.g. java.awt.Rectangle[x=100,y=100,width=100,height=100] java.awt.Rectangle[x=200,y=100,width=100,height=100] java.awt.Rectangle[x=300,y=100,width=100,height=100] The reason why I used GridLayout instead of gridBagLayout is that, I want each pictures to have boundary. If I use GridBagLayout, the grid will expand according to the picture size. I want grid size to be in fix size. JPanel pDraw = new JPanel(new GridLayout(6,6)); pDraw.setPreferredSize(new Dimension(600,600)); for (int i =0; i<(6*6); i++) { //get random number for height and width of the image int x = rand.nextInt(40)+(50); int y = rand.nextInt(40)+(50); ImageIcon icon = createImageIcon("bird.jpg"); //rescale the image according to the size selected Image img = icon.getImage().getScaledInstance(x,y,img.SCALE_SMOOTH); icon.setImage(img ); JLabel label = new JLabel(icon); pDraw.add(label); } for(Component component:components) { //retrieve the coordinate System.out.println(component.getBounds()); }
