  • First-time software contractor, building a system for a multi-site client; who should own the intell

    - by matthew
    I'm very new to software contracting; this is my first project. I've just built a point-of-sale software system for a client, and neither of us put a lot of work into the contract. I wrote that the software was "jointly owned" with exclusive license for use given to the client. The client is using it at one store and is very pleased with it. The client is also planning to expand to numerous stores over time, and wants to use it in every store. The client also now wants full ownership of the software, with me as the exclusive developer. I am very hesitant to allow this, and I am seeking previous experience. Should I sell the IP but demand royalties for every site at which it's installed? Should I demand royalties for every sale made using the software? Should I really start talking to a lawyer? A couple of other details: in terms of risk, it is fair to say that the client is assuming the risk, but the client is now using the software and exclaiming how great it is (and so I assume, how it is improving business). Also, the software is tailored to the client specifically, but could, with a bit of work, be repackaged and resold to other clients. Even if the client owned the IP I would certainly want to make sure that I then did have (significant) royalties on such sales.

  • EF code first error "The specified index already exists. [ IX_Id ]" for object tree

    - by PascalN
    Using EF code first 4.3 I'm trying to model an object tree with a required-required relationships and a required-optional relationships. Here is a simple representation of those classes public class Top { public int Id { get; set; } public virtual Middle Middle { get; set; } } public class Middle { public int Id { get; set; } public virtual Child Child { get; set; } } public class Child { public int Id { get; set; } } Here is the OnModelCreating code modelBuilder.Entity<Top>().HasRequired(t => t.Middle).WithRequiredPrincipal().WillCascadeOnDelete(); modelBuilder.Entity<Middle>().HasRequired(t => t.Child).WithOptional().WillCascadeOnDelete(); This produces the error "The specified index already exists. [ IX_Id ]" on SQLCE After checking the db schema, both model binder fluent API configuration lines create an index IX_Id on the table Middles. Does anyone know how to work around that problem? Is there a way to set the index name? Thank you! Pascal

  • How To Select First Ancestor That Matches A Selector?

    - by Zach
    General: How can I select the first matching ancestor of an element in jQuery? Example: Take this HTML block <table> <tbody> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> </tbody> </table> I can remove a row in the table by clicking "Remove" using this jQuery code: $('.remove').click(function(){ $(this).parent().parent().hide(); return false; }); This works, but it's pretty fragile. If someone puts the <a> into a <div>, for example, it would break. Is there a selector syntax in jQuery that follows this logic: "Here's an element, now find the closest ancestor that matches some selection criteria and return it" Thanks

  • WPF Storyboard works well, except for the first time it runs. Why?

    - by sofri
    Hi, I'm doing a Surface Application. And there I have something like a bulletin board where little cards with news on it are pinned on. On click they shall fly out of the board and scale bigger. My storyboard works well, except for the first time it runs. It's not a smooth animation then but it scales to its final size immediately and it's the same with the orientation-property. Just the center-property seems to behave correctly. This is an example for one of my Storyboards doing that: Storyboard stb = new Storyboard(); PointAnimation moveCenter = new PointAnimation(); DoubleAnimationUsingKeyFrames changeWidth = new DoubleAnimationUsingKeyFrames(); DoubleAnimationUsingKeyFrames changeHeight = new DoubleAnimationUsingKeyFrames(); DoubleAnimationUsingKeyFrames changeOrientation = new DoubleAnimationUsingKeyFrames(); moveCenter.From = News1.ActualCenter; moveCenter.To = new Point(250, 400); moveCenter.Duration = new Duration(TimeSpan.FromSeconds(1.0)); moveCenter.FillBehavior = FillBehavior.Stop; stb.Children.Add(moveCenter); Storyboard.SetTarget(moveCenter, News1); Storyboard.SetTargetProperty(moveCenter, new PropertyPath(ScatterViewItem.CenterProperty)); changeWidth.Duration = TimeSpan.FromSeconds(1); changeWidth.KeyFrames.Add(new EasingDoubleKeyFrame(266, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeWidth.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeWidth); Storyboard.SetTarget(changeWidth, News1); Storyboard.SetTargetProperty(changeWidth, new PropertyPath(FrameworkElement.WidthProperty)); changeHeight.Duration = TimeSpan.FromSeconds(1); changeHeight.KeyFrames.Add(new EasingDoubleKeyFrame(400, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeHeight.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeHeight); Storyboard.SetTarget(changeHeight, News1); Storyboard.SetTargetProperty(changeHeight, new PropertyPath(FrameworkElement.HeightProperty)); changeOrientation.Duration = TimeSpan.FromSeconds(1); changeOrientation.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeOrientation.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeOrientation); Storyboard.SetTarget(changeOrientation, News1); Storyboard.SetTargetProperty(changeOrientation, new PropertyPath(ScatterViewItem.OrientationProperty)); stb.Begin(this); News1.Center = new Point(250, 400); News1.Orientation = 0; News1.Width = 266; News1.Height = 400; Pin1.Visibility = Visibility.Collapsed; news1IsOutside = true; Scroll1.IsEnabled = true; What's wrong with it?

  • My UITabBarController isn't appearing, but its first view is?

    - by E-Madd
    I've done some reorganizing of my project recently and now I'm not seeing my tab bar controller, but its first view controller's view is appearing. Here's a breakdown of everything that happens prior to the problem. App Delegate loads FirstViewController with nib. FirstViewController loads the application data from my server and then presents MainViewController with a modal transition. MainViewController is where the UITabBarController is supposed to be appearing. It's a very simple class. The .h @interface MainViewController : UIViewController <UITabBarControllerDelegate> { IBOutlet UITabBarController *tabBarController; } @property (nonatomic, retain) UITabBarController *tabBarController; @end The .m @implementation MainViewController @synthesize tabBarController; - (void)viewDidLoad { NSLog(@"MainViewController viewDidLoad"); //set tab bar controller delegate to self tabBarController.delegate = self; // home view HomeViewController *home = [[HomeViewController alloc] initWithTab]; // menu view MenuViewController *menu = [[MenuViewController alloc] initWithTab]; // special offers view SpecialOffersViewController *so = [[SpecialOffersViewController alloc] initWithTab]; // events view EventsViewController *events = [[EventsViewController alloc] initWithTab]; // info view InfoViewController *info = [[InfoViewController alloc] initWithTab]; //populate the tab bar controller with view controllers NSArray *controllers = [NSArray arrayWithObjects:home, menu, so, events, info, nil]; tabBarController.viewControllers = controllers; //release view controllers [home release]; [menu release]; [so release]; [events release]; [info release]; [controllers release]; //add tab bar controller to view [self.view addSubview:tabBarController.view]; [super viewDidLoad]; } and here's the bit from FirstViewController that modally presents the MainViewController... MainViewController *controller = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; I'm not getting any compiler errors or warnings and the app runs swell... no crashing. It just isn't showing the darned TabBar, and it used to when I was creating it on my AppDelegate. I checked everything in my NIB and my outlets seem to be hooked up ok. I have no idea what's happened. Help!

  • Fast response on first Socket I/O request but slow every other time when communicating with remote serial port

    - by GreenGodot
    I'm using sockets to pass Serial commands to a remote device. And the response to that request is sent back and printed out. However, I am having a problem in that the first time it is instant but the rest of the time it can take up to 20 seconds to receive a reply. I think the problem is with my attempt at threading but I am not entirely sure. new Thread() { @Override public void run() { System.out.println("opened"); try { isSocketRetrieving.setText("Opening Socket"); socket = new Socket(getAddress(), getRemotePort())); DataOutput = new DataOutputStream(socket .getOutputStream()); inFromServer = new BufferedReader( new InputStreamReader(socket .getInputStream())); String line = ""; isSocketRetrieving.setText("Reading Stream......"); while ((line = inFromServer.readLine()) != null) { System.out.println(line); if (line.contains(getHandshakeRequest())) { DataOutput.write((getHandshakeResponse()toString() + "\r").getBytes()); DataOutput.flush(); DataOutput .write((getCommand().toString() + "\r").getBytes()); DataOutput.flush(); int pause = (line.length()*8*1000)/getBaud(); sleep(pause); } else if (line.contains(readingObject .getExpected())) { System.out.println(line); textArea.append("value = " + line + "\n"); textAreaScroll.revalidate(); System.out.println("Got Value"); break; } } System.out.println("Ended"); try { inFromServer.close(); DataOutput.close(); socket.close(); isSocketRetrieving.setText("Socket is inactive..."); rs232Table.addMouseListener(listener); interrupt(); join(); } catch (IOException e) { e.printStackTrace(); } catch (InterruptedException e) { System.out.println("Thread exited"); } } catch (NumberFormatException e1) { e1.printStackTrace(); } catch (UnknownHostException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }.start();

  • How to give the First image in a gallery a different class than the rest of the images - Carrierwave

    - by ChrisBedoya
    I have a model called "Photo" that belongs to a model called "Shoe". I using Carrierwave to upload multiple images. index.html.erb <% shoes.each do |shoe| %> <div class="shoe"> <div class="gallery"> <% shoe.photos.each do |photo| %> <%= link_to image_tag(photo.photo_file.url(:thumb).to_s), photo.photo_file.url.to_s, :class => 'fancybox', :rel => 'gallery' %> <% end %> </div> </div> <% end %> Outputs this: <div class="shoe"> <div class="gallery"> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> </div> </div> But I want the first image of each gallery to be able to have its own class and the rest of the images to have their own class. Something like this: <a class="firstclass" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> How can I do this? Also I want each gallery to have its own unique id but when I try to add this: :rel => 'gallery<%= shoe.id %>' I get a Syntax error. Thanks.

  • Which work process in my company should I Improve first?

    - by shoren
    I've just started to work in a new place, and I see several things they do that I find really terrible, and I want to know if they are indeed so wrong, or I am just too strict. Please let me know if my criticism is in place, and your opinion on which problem is the worst and should be fixed first. The developement is all in Java. 1) Not using svnignore. This means svn stat can't be used, and developers forget to add files and break the build. 2) Generated files go to same folders as committed files. Can't use simple maven clean, have to find them one by one. Maven clean doesn't remove all of them. 3) Not fixing IDE analyze warnings. Analyze code returns about 5,000 warning, of many different kinds. 4) Not following conventions: spring beans names sometimes start with uppercase and sometimes not, ant properties sometimes with underline and sometimes with dots delimiter, etc. 5) Incremental build takes 6 minutes, even when nothing is changed. 6) Developers only use remote debug, and don't know how to run the Tomcat server internally from the IDE. 7) Developers always restart the server after every compilation, instead of dynamically reloading the class and saving the server's state. It takes them at least 10 minutes to start checking any change in the code. 8) Developers only compile from command line. When there are compilation errors, they manually open the file and go the the problematic line. 9) A complete mess in project dependencies. Over 200 open sources are depended on, and no one knows what is indeed needed and why. They do know that not all dependencies are necessary. 10) Mixing Maven and Ant in a way that disables the benefits of both. In one case, even dependency checks are not done by Maven. 11) Not using generics properly. 12) Developers don't use Subversion integration with IDE (Eclipse, Intellij Idea). What do you think? Where should I start? Is any of the things I mentioned not really a problem?

  • Function to get the font and calculate the width of the string not working on first instance

    - by user3627265
    I'm trying to calculate the width of the string based on the font style and size. The user will provide the string, the font style and the font size, and then after giving all the data the user will hit the submit button and the function will trigger. Basically this script works but only when the submit button is hit twice or the font is selected twice,. I mean if you selec DNBlock as a font, it will not work for first time, but the second time you hit submit, it will then work. I'm not sure where is the problem here, but when I used the default font style like Arial, times new roman etc it works perfectly fine. Any Idea on this? I suspected that the font style is not being rendered by the script or something. Correct me if I'm wrong. Thanks //Repeat String String.prototype.repeat = function( num ) { return new Array( num + 1 ).join( this ); } //Calculate the width of string String.prototype.textWidth = function() { var fntStyle = document.getElementById("fntStyle").value; if(fntStyle == "1") { var fs = "DNBlock"; } else if(fntStyle == "2") { var fs = "DNBlockDotted"; } else if(fntStyle == "3") { var fs = "DNCursiveClassic"; } else if(fntStyle == "4") { var fs = "DNCursiveDotted"; } else if(fntStyle == "5") { var fs = "FoundationCursiveDots-Regul"; } var f = document.getElementById("fntSize").value.concat('px ', fs), o = $('<div>' + this + '</div>') .css({'position': 'absolute', 'float': 'left', 'white-space': 'nowrap', 'visibility': 'hidden', 'font': f}) .appendTo($('body')), w = o.width(); o.remove(); return w; } //Trigger the event $("#handwriting_gen").submit(function () { var rptNO = parseInt($('#rptNO').val()); $("[name='txtLine[]']").each(function(){ alert(this.value.repeat(rptNO).textWidth()); if(this.value.repeat(rptNO).textWidth() > 1000) { $(this).focus(); $(this).css({"background-color":"#f6d9d4"}).siblings('span.errorMsg').text('Text is too long.'); event.preventDefault(); } }); });

  • One email user keeps disconnecting from our exchange server

    - by Funky Si
    I have one user who keeps reporting that Outlook keeps disconnecting from our email server. All other users are fine. Our email server is running Exchange 2010 and the client is running Outlook 2003. The disconnection only lasts a moment. I have checked for logs on the client and Exchange server and can not see any reason for the disconnect, On the Client I get EventId 26 telling me Outlook has disconnected and reconnected but no reason why. Can anyone give me some suggestions of things to try and track down where the problem could be? --Update-- I have found the following log file C:\Program Files\Microsoft\Exchange Server\V14\Logging\RPC Client Access which suggests that it is a problem with RPC sessions.

  • Is there a way to disable a UITabBarItem from reloading its first view?

    - by Tanner
    Hi All, I currently have an app that is a tab bar style app and supports rotation. Everything is great until you hit the tab bar when the device is in landscape and the original view is reloaded and placed back on screen. There is a lot of space and the overall appearance doesnt look good. Is there a way to disable this tab bar item from doing this?? Any help is greatly appreciated, Thanks

  • Queyring container with Linq + group by ?

    - by Prix
    public class ItemList { public int GuID { get; set; } public int ItemID { get; set; } public string Name { get; set; } public entityType Status { get; set; } public class Waypoint { public int Zone { get; set; } public int SubID { get; set; } public int Heading { get; set; } public float PosX { get; set; } public float PosY { get; set; } public float PosZ { get; set; } } public List<Waypoint> Routes = new List<Waypoint>(); } I have a list of items using the above class and now I need to group it by ItemID and join the first entry of Routes of each iqual ItemID. So for example, let's say on my list I have: GUID ItemID ListOfRoutes 1 23 first entry only 2 23 first entry only 3 23 first entry only 4 23 first entry only 5 23 first entry only 6 23 first entry only 7 23 first entry only Means I have to group entries 1 to 7 as 1 Item with all the Routes entries. So I would have one ItemID 23 with 7 Routes on it where those routes are the first element of that given GUID Routes List. My question is if it is possible using LINQ to make a statment to do something like that this: var query = from ItemList entry in myList where status.Contains(entry.Status) group entry by entry.ItemID into result select new { items = new { ID = entry.ItemID, Name = entry.Name }, routes = from ItemList m in entry group m.Routes.FirstOrDefault() by n.NpcID into m2 }; So basicly I would have list of unique IDS information with a inner list of all the first entry of each GUID route that had the same ItemID. <<< UPDATE: This would be an example of public List<ItemList> myList = new List<ItemList>(); data: GUID ItemID ListOfRoutes 1 20 Routes[1] 2 20 Routes[2] 3 20 Routes[3] 4 20 Routes[4] 5 20 Routes[5] 6 55 Routes[6] 7 55 Routes[7] 8 55 Routes[8] 9 1 Routes[9] 10 1 Routes[10] As you can see GUID is unique, ItemID can reapeat it self. Each GUID has a Routes list and all routes list have a minimum of 1 entry and above. Routes example. Routes[1] have: Entry Zone SubID Heading PosX PosY PosZ 1 1200 0 100 1029.32 837.21 29.10 2 1200 0 120 1129.32 537.21 29.10 3 1200 0 180 1229.32 137.21 29.10 4 1200 0 360 1329.32 437.21 29.10 5 1200 0 100 1429.32 637.21 29.10 Routes[2] have: Entry Zone SubID Heading PosX PosY PosZ 1 100 0 10 129.32 437.21 29.10 So what I want to do is a list of all entries I have on myList grouped by ItemID maintainning the fields ItemID and Name ... and a new field or item that will have all the first elements of Routes of those GUIDs. For example ItemID 20 would produce the follow result: ItemID, Name, ListOfRoutes This ItemID ListOfRoutes would contain Routes[1] first entry: Entry Zone SubID Heading PosX PosY PosZ 1 1200 0 100 1029.32 837.21 29.10 Routes[2] first entry: Entry Zone SubID Heading PosX PosY PosZ 1 100 0 10 129.32 437.21 29.10 Routes[3], Routes[4], Routes[5] first entries. Example of how myList is feeded: ItemList newItem = new ItemList(); newItem.GUID = GUID; newItem.ItemID = ItemID; newItem.Name = Name; newItem.Status = Status; // Item location ItemList.Waypoint itemLocation = new ItemList.Waypoint(); itemLocation.SubID = SubID; itemLocation.Zone = Zone; itemLocation.Heading = convertHeading(Heading); itemLocation.PosX = PosX; itemLocation.PosY = PosY; itemLocation.PosZ = PosZ; itemLocation.Rest = Rest; newItem.Routes.Add(itemLocation); myList.Add(newItem);

  • Why does this only work sometimes? (UITextView resign first responder question)

    - by RexOnRoids
    When a user presses the "SEND"(return) button I want the keyboard to retract and do other stuff like send a message. But it only works SOMETIMES... Why does this code only work SOMETIMES? I need it to work all the time obviously, but it doesn't. - (void)textViewDidChange:(UITextView *)inTextView { NSString *text = myTextView.text; if ([text length] > 0 && [text characterAtIndex:[text length] -1] == '\n') { myTextView.text = [text substringToIndex:[text length] -1]; [myTextView resignFirstResponder]; [self sendMessage]; } }

  • What sorting algorithm is this?

    - by Mike
    Hi, I have a sorting algorithm as follows. My question is, which sorting algorithm is this? I thought it was bubble sort, but it does not do multiple runs. Any idea? Thanks! //sorting in descending order struct node { int value; node* NEXT; } //Assume HEAD pointer denotes the first element in the //linked list // only change the values…don’t have to change the //pointers Sort( Node *Head) { node* first,second,temp; first= Head; while(first!=null) { second=first->NEXT; while(second!=null) { if(first->value < second->value) { temp = new node(); temp->value=first->value; first->value=second->value; second->value=temp->value; delete temp; } second=second->NEXT; } first=first->NEXT; } }

  • Should we seal Singletons? Should we try to inherit from Singletons in the first place?

    - by devoured elysium
    Should a Singleton class be allowed to have children? Should we seal it? What are the pro's and con's? For being able to inherit from a Singleton class, we would have to make the constructor protected instead of private. Now, that will be fine in c#, but the protected word in java gives both child-classes and package-classes access to the constructor. Which means not only classes that inherit from our Singleton can access the constructor but other classes in the same package can do it. I'm a bit confused about all this facts. Maybe I am making a big fuss about nothing to worry about too much? Until now, I never had any necessity of trying to inherit from a Singleton, so maybe this is just an academic question! Thanks
