  • Firefox add-on for examining z-indexes

    - by hekevintran
    I'm working on a fairly large site and am having trouble managing z-indexes. Is there a Firefox add-on that will look at a page and give me an ordered list of every element with a z-index declared? That would save a ton of times for the cases where a z-index was wrong or hard to find.

  • hibernate column uniqueness question

    - by Seth
    I'm still in the process of learning hibernate/hql and I have a question that's half best practices question/half sanity check. Let's say I have a class A: @Entity public class A { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Column(unique=true) private String name = ""; //getters, setters, etc. omitted for brevity } I want to enforce that every instance of A that gets saved has a unique name (hence the @Column annotation), but I also want to be able to handle the case where there's already an A instance saved that has that name. I see two ways of doing this: 1) I can catch the org.hibernate.exception.ConstraintViolationException that could be thrown during the session.saveOrUpdate() call and try to handle it. 2) I can query for existing instances of A that already have that name in the DAO before calling session.saveOrUpdate(). Right now I'm leaning towards approach 2, because in approach 1 I don't know how to programmatically figure out which constraint was violated (there are a couple of other unique members in A). Right now my DAO.save() code looks roughly like this: public void save(A a) throws DataAccessException, NonUniqueNameException { Session session = sessionFactory.getCurrentSession(); try { session.beginTransaction(); Query query = null; //if id isn't null, make sure we don't count this object as a duplicate if(obj.getId() == null) { query = session.createQuery("select count(a) from A a where a.name = :name").setParameter("name", obj.getName()); } else { query = session.createQuery("select count(a) from A a where a.name = :name " + "and a.id != :id").setParameter("name", obj.getName()).setParameter("name", obj.getName()); } Long numNameDuplicates = (Long)query.uniqueResult(); if(numNameDuplicates > 0) throw new NonUniqueNameException(); session.saveOrUpdate(a); session.getTransaction().commit(); } catch(RuntimeException e) { session.getTransaction().rollback(); throw new DataAccessException(e); //my own class } } Am I going about this in the right way? Can hibernate tell me programmatically (i.e. not as an error string) which value is violating the uniqueness constraint? By separating the query from the commit, am I inviting thread-safety errors, or am I safe? How is this usually done? Thanks!

  • AVFoundation buffer comparison to a saved image

    - by user577552
    Hi, I am a long time reader, first time poster on StackOverflow, and must say it has been a great source of knowledge for me. I am trying to get to know the AVFoundation framework. What I want to do is save what the camera sees and then detect when something changes. Here is the part where I save the image to a UIImage : if (shouldSetBackgroundImage) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // Create a bitmap graphics context with the sample buffer data CGContextRef context = CGBitmapContextCreate(rowBase, bufferWidth, bufferHeight, 8, bytesPerRow, colorSpace, kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst); // Create a Quartz image from the pixel data in the bitmap graphics context CGImageRef quartzImage = CGBitmapContextCreateImage(context); // Free up the context and color space CGContextRelease(context); CGColorSpaceRelease(colorSpace); // Create an image object from the Quartz image UIImage * image = [UIImage imageWithCGImage:quartzImage]; [self setBackgroundImage:image]; NSLog(@"reference image actually set"); // Release the Quartz image CGImageRelease(quartzImage); //Signal that the image has been saved shouldSetBackgroundImage = NO; } and here is the part where I check if there is any change in the image seen by the camera : else { CGImageRef cgImage = [backgroundImage CGImage]; CGDataProviderRef provider = CGImageGetDataProvider(cgImage); CFDataRef bitmapData = CGDataProviderCopyData(provider); char* data = CFDataGetBytePtr(bitmapData); if (data != NULL) { int64_t numDiffer = 0, pixelCount = 0; NSMutableArray * pointsMutable = [NSMutableArray array]; for( int row = 0; row < bufferHeight; row += 8 ) { for( int column = 0; column < bufferWidth; column += 8 ) { //we get one pixel from each source (buffer and saved image) unsigned char *pixel = rowBase + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); unsigned char *referencePixel = data + (row * bytesPerRow) + (column * BYTES_PER_PIXEL); pixelCount++; if ( !match(pixel, referencePixel, matchThreshold) ) { numDiffer++; [pointsMutable addObject:[NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH - (column/ (float) bufferHeight)* SCREEN_WIDTH - 4.0, (row/ (float) bufferWidth)* SCREEN_HEIGHT- 4.0)]]; } } } numberOfPixelsThatDiffer = numDiffer; points = [pointsMutable copy]; } For some reason, this doesn't work, meaning that the iPhone detects almost everything as being different from the saved image, even though I set a very low threshold for detection in the match function... Do you have any idea of what I am doing wrong?

    I'd like to configure CKEditor to save accented letters as they are, and don't change them to their HTML equivalent, since I'm working work with UTF8 anyway. Where and what do I need to set to achieve this? Example: Current: entered: áéíóúöoüu source: <p>&aacute;&eacute;&iacute;&oacute;&uacute;&ouml;o&uuml;u</p> Wished for: entered: áéíóúöoüu source: <p>áéíóúöoüu</p>

  • Which offer to pick?

    - by Shawn
    OK. This is kinda silly, but I'd really like to hear what you guys say. Here is the thing: I used to be an php developer and started looking for jobs 3 weeks ago and now I got 2 offers at hand. If I took the first one what I do would be 100% in PHP - simply dev works on a ecommerce project. If I go with the second one, the projects would be in python which I didn't have too much experiences on and is kinda exited about the new stuff I'm going to learn. But wait, the first offer gives more money(1k plus) and that's why I'm still hesitating and troubling you guys.) If you were me, which one would you pick? I know there could be other factors to be considered like 'which position is closer to your home so you could take good care of your dog', well let's forget about those things for now.

  • How to make and use first object in Objective C to store sender tag

    - by dbonneville
    I started with a sample program that simply sets up a UIView with some buttons on it. Works great. I want to access the sender tag from each button and save it. My first thought was to save it to a global variable but I couldn't get it to work right. I thought the best way would be to create an object with one property and synthesize it so I can get or set it as needed. First, I created GlobalGem.h: #import <Foundation/Foundation.h> @interface GlobalGem : NSObject { int gemTag; } @property int gemTag; -(void) print; @end Then I created GlobalGem.m: #import "GlobalGem.h" @implementation GlobalGem @synthesize gemTag; -(void) print { NSLog(@"gemTag value is %i", gemTag); } @end The sample code I worked from doesn't do anything I can see in "main" where the program initializes. They just have their methods and are set up to handle IBOutlet actions. I want to use this object in the IBOutlet methods. But I don't know where to create the object. In the viewDidLoad, I tried this: GlobalGem *aGem = [[GlobalGem alloc]init]; [aGem print]; I added reference to the .h file of course. The print method works. In the nslog I get "gemTag value is 0". But now I want to use the instance aGem in some of the IBOutlet actions. For instance, if I put this same method in one of the outlet actions like this: - (IBAction)touchButton:(id)sender { [aGem print]; } ...I get a build error saying that "aGem is undeclared". Yes, I'm new to objective c and am very confused. Is the instance I created, aGem, in the viewDidLoad not accessible outside of that method? How would I create an instance of a Class that I can store a variable value that any of the IBOutlet methods can access? All the buttons need to be able to store their sender tag in the instance aGem and I'm stuck. As I mentioned earlier, I was able to write the sender tag to a global variable I declared in the UIView .h file that came with the program, but I ran into issues using it. Where am I off?

  • FullCalendar Events: Confused how to enable resizing.

    - by Josiah Kiehl
    I'm using the FullCalendar plugin, and am very pleased with it, however I can't figure out how to enable resizing. I looked at the source of the calendar on the main FullCalendar page, and my code is no different save that I get my events from a source rather than explicitly define them. What am I missing? $('#schedule').fullCalendar({ events: '/campaigns/scheduled', editable: true });

  • Loading XML from Web Service

    - by Lukasz
    I am connecting to a web service to get some data back out as xml. The connection works fine and it returns the xml data from the service. var remoteURL = EveApiUrl; var postData = string.Format("userID={0}&apikey={1}&characterID={2}", UserId, ApiKey, CharacterId); var request = (HttpWebRequest)WebRequest.Create(remoteURL); request.Method = "POST"; request.ContentLength = postData.Length; request.ContentType = "application/x-www-form-urlencoded"; // Setup a stream to write the HTTP "POST" data var WebEncoding = new ASCIIEncoding(); var byte1 = WebEncoding.GetBytes(postData); var newStream = request.GetRequestStream(); newStream.Write(byte1, 0, byte1.Length); newStream.Close(); var response = (HttpWebResponse)request.GetResponse(); var receiveStream = response.GetResponseStream(); var readStream = new StreamReader(receiveStream, Encoding.UTF8); var webdata = readStream.ReadToEnd(); Console.WriteLine(webdata); This prints out the xml that comes from the service. I can also save the xml as an xml file like so; TextWriter writer = new StreamWriter(@"C:\Projects\TrainingSkills.xml"); writer.WriteLine(webdata); writer.Close(); Now I can load the file as an XDocument to perform queries on it like this; var data = XDocument.Load(@"C:\Projects\TrainingSkills.xml"); What my problem is that I don't want to save the file and then load it back again. When I try to load directly from the stream I get an exception, Illegal characters in path. I don't know what is going on, if I can load the same xml as a text file why can't I load it as a stream. The xml is like this; <?xml version='1.0' encoding='UTF-8'?> <eveapi version="2"> <currentTime>2010-04-28 17:58:27</currentTime> <result> <currentTQTime offset="1">2010-04-28 17:58:28</currentTQTime> <trainingEndTime>2010-04-29 02:48:59</trainingEndTime> <trainingStartTime>2010-04-28 00:56:42</trainingStartTime> <trainingTypeID>3386</trainingTypeID> <trainingStartSP>8000</trainingStartSP> <trainingDestinationSP>45255</trainingDestinationSP> <trainingToLevel>4</trainingToLevel> <skillInTraining>1</skillInTraining> </result> <cachedUntil>2010-04-28 18:58:27</cachedUntil> </eveapi> Thanks for your help!

  • Advice on creating admin panel where user can upload, remove and order the files

    - by Manoj
    I'm working on a website where a logged-in admin needs the ability to upload and manage multiple PDFs from their computer. They'd need to be able to upload/remove the files. Also, there would need to be a way that they can sort the list of uploaded files and save that order so that other visitors to the page would see the list of files in that particular order. I looked into jQuery Uploadify among other things. Would javascript be the right way to go? Thanks, Manoj

  • Highlighting company name in Eclipse stack traces

    - by Robin Green
    Is there a way to make Eclipse highlight com.company (where for company substitute the name of the company you work for) in stack traces? It would make it fractionally easier and faster to home in on which parts of the stack trace were ours, and which were third-party code. I tried the logview plugin here, and while it does work, it makes the location information in the stack traces unclickable, which means I would waste more time than I would save.

  • plot of multiple line segments on 2D plot in Mathematica

    - by Bruce
    Hi, I would like to plot multiple, perhaps thousands of line segments on a single 2D plot in Mathematica. These line segments would be determined from an algorithm that would detected and save each segments endpoints. Once the algorithm has determined all the line segments within a finite 2D plot domain and range (e.g., x = 0,4 and y=0,0.5), I would like to plot them all on a single plot. Thanks for any suggestions.

  • problem with reload data from table view after come back from another view

    - by user129677
    I have a problem in my application. Any help will be greatly appreciated. Basically it is from view A to view B, and then come back from view B. In the view A, it has dynamic data loaded in from the database, and display on the table view. In this page, it also has the edit button, not on the navigation bar. When user tabs the edit button, it goes to the view B, which shows the pick view. And user can make any changes in here. Once that is done, user tabs the back button on the navigation bar, it saves the changes into the NSUserDefaults, goes back to the view A by pop the view B. When coming back to the view A, it should get the new data from the UIUserDefaults, and it did. I user NSLog to print out to the console and it shows the correct data. Also it should invoke the viewWillAppear: method to get the new data for the table view, but it didn't. It even did not call the tableView:numberOfRowsInSection: method. I place a NSLog statement inside this method but didn't print out in the console. as the result, the view A still has the old data. the only way to get the new data in the view A is to stop and start the application. both view A and view B are the subclass of UIViewController, with UITableViewDelegate and UITableViewDataSource. here is my code in the view A : - (void)viewWillAppear:(BOOL)animated { NSLog(@"enter in Schedule2ViewController ..."); // load in data from database, and store into NSArray object //[self.theTableView reloadData]; [self.theTableView setNeedsDisplay]; //[self.theTableView setNeedsLayout]; } in here, the "theTableView" is a UITableView variable. And I try all three cases of "reloadData", "setNeedsDisplay", and "setNeedsLayout", but didn't seem to work. in the view B, here is the method corresponding to the back button on the navigation bar. - (void)viewDidLoad { UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:@selector(savePreference)]; self.navigationItem.leftBarButtonItem = saveButton; [saveButton release]; } - (IBAction) savePreference { NSLog(@"save preference."); // save data into the NSUSerDefaults [self.navigationController popViewControllerAnimated:YES]; } Am I doing in the right way? Or is there anything that I missed? Many thanks.

  • Must have JavaScript pro developer tools, libs, utilities and workshop configuration.

    - by WooYek
    This is a followup question to the Pro JavaScript programmer interview questions (with answers). What is considered professional and industrial standard for a professional browser side Java Script developer when it comes to his workshop configuration, and maybe from-concept-to-shipment process? What are the most popular IDE's, utilities and probably libraries, not limited to the free ones. These that can help cut development time (eg. IDE), help with achieve better quality (eg. unit testing tools), reliability and maintainability. I'm looking for a baseline to which I could compare potential candidates based on their ability to keep their tools sharp and workshop efficient (pro's should invest time&money in good tools, right?).
