  • Is there ever a good reason to store time not in UTC?

    - by landon9720
    I am wondering if there are any good reasons to ever store time information in anything other that UTC (GMT)? I believe that this is a solid rule for all software engineering. The conversion to local time is merely a translation that happens at the UI layer for display purposes. I have also seen cases where the translatation is needed in order to implement an algorithm correctly (for handling midnight date changes, etc.).

  • What's the correct way to instantiate an IRepository class from the Controller?

    - by GenericTypeTea
    I have the following project layout: MVC UI |...CustomerController (ICustomerRepository - how do I instantiate this?) Data Model |...ICustomerRepository DAL (Separate Data access layer, references Data Model to get the IxRepositories) |...CustomerRepository (inherits ICustomerRepository) What's the correct way to say ICustomerRepository repository = new CustomerRepository(); when the Controller has no visibility to the DAL project? Or am I doing this completely wrong?

  • How to extract data out of a specific PHP array

    - by user77413
    I have a multi-dimensional array that looks like this: The base array is indexed based on category ids from my catalog. $categories[category_id] Each base array has two underlying elements: ['parent_category_id'] ['sort_order'] I want to create a function that allows us to create a list of categories for a given parent_category_id in the correct sort order. Is this possible? Technically it is the same information, but the array is constructed in a weird way to extract that information.

  • Internal classes with ADO.NET Entity Framework

    - by Regent
    I'm using Entity Framework for creation of my Data Access Layer and I want for all of my classes to be internal. I know it is possible to manually assign it manually in the designer for each class. But looks like it also requires to set internal modifier for each single property in every class! I have about 30+ entities and it will be a huge work to do. Do you know any ideas how to set a 'default access' for the entire model?

  • Show information over image on rollover

    - by Chris
    I want to be able to show information (HTML basically) over an image when the mouse rolls over the image... I know there is a .hover() jQuery function but am unsure how to use it to get the desired effect. Ideally when a user hovers over an image it would "grey out" (e.g. layer of 50% opacity black) with some HTML like a title etc etc. Can someone point me in the right direction or provide sample code Thanks

  • Calling a webservice synchronously from a Silverlight 3 application?

    - by Lasse V. Karlsen
    I am trying to reuse some .NET code that performs some calls to a data-access-layer type service. I have managed to package up both the input to the method and the output from the method, but unfortunately the service is called from inside code that I really don't want to rewrite in order to be asynchronous. Unfortunately, the webservice code generated in Silverlight only produces asynchronous methods, so I was wondering if anyone had working code that managed to work around this? I tried the recipe found here: The Easy Way To Synchronously Call WCF Services In Silverlight, but unfortunately it times out and never completes the call. Or rather, what seems to happen is that the completed event handler is called, but only after the method returns. I am suspecting that the event handler is called from a dispatcher or similar, and since I'm blocking the main thread here, it never completes until the code is actually back into the GUI loop. Or something like that. Here's my own version that I wrote before I found the above recipe, but it suffers from the same problem: public static object ExecuteRequestOnServer(Type dalInterfaceType, string methodName, object[] arguments) { string securityToken = "DUMMYTOKEN"; string input = "DUMMYINPUT"; object result = null; Exception resultException = null; object evtLock = new object(); var evt = new System.Threading.ManualResetEvent(false); try { var client = new MinGatServices.DataAccessLayerServiceSoapClient(); client.ExecuteRequestCompleted += (s, e) => { resultException = e.Error; result = e.Result; lock (evtLock) { if (evt != null) evt.Set(); } }; client.ExecuteRequestAsync(securityToken, input); try { var didComplete = evt.WaitOne(10000); if (!didComplete) throw new TimeoutException("A data access layer web service request timed out (" + dalInterfaceType.Name + "." + methodName + ")"); } finally { client.CloseAsync(); } } finally { lock (evtLock) { evt.Close(); evt = null; } } if (resultException != null) throw resultException; else return result; } Basically, both recipes does this: Set up a ManualResetEvent Hook into the Completed event The event handler grabs the result from the service call, and signals the event The main thread now starts the web service call asynchronously It then waits for the event to become signalled However, the event handler is not called until the method above has returned, hence my code that checks for evt != null and such, to avoid TargetInvocationException from killing my program after the method has timed out. Does anyone know: ... if it is possible at all in Silverlight 3 ... what I have done wrong above?

  • Converting OpenGL coordinates to lower UIView (and UIImagePickerController)

    - by John Qualis
    I am new to OpenGL on the iPhone. I am developing an iPhone app similar to a barcode reader but with an extra OpenGL layer. The bottommost layer is UIImagePickerController, then I use UIView on top and draw a rectangle at certain coordinates on the iPhone screen. So far everything is OK. Then I am trying to draw an OpenGL 3-D model in that rectangle. I am able to load a 3-D model in the iPhone based on this code here - http://iphonedevelopment.blogspot.com/2008/12/start-of-wavefront-obj-file-loader.html I am not able to transform the coordinates of the rectangle into OpenGL coordinates. Appreciate any help. Do I need to use a matrix to translate the currentPosition of the 3-D model so it is drawn within myRect? The code is given below. -(void)setupView:(GLView*)view { const GLfloat zNear = 0.01, zFar = 1000.0, fieldOfView = 45.0; GLfloat size; glEnable(GL_DEPTH_TEST); glMatrixMode(GL_PROJECTION); size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); CGRect rect = view.bounds; glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glViewport(0, 0, rect.size.width, rect.size.height); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClearColor(0.0f, 0.0f, 0.0f, 0.0f); NSString *path = [[NSBundle mainBundle] pathForResource:@"plane" ofType:@"obj"]; OpenGLWaveFrontObject *theObject = [[OpenGLWaveFrontObject alloc] initWithPath:path]; Vertex3D position; position.z = -8.0; position.y = 3.0; position.x = 2.0; theObject.currentPosition = position; self.plane = theObject; [theObject release]; } - (void)drawView:(GLView*)view; { static GLfloat rotation = 0.0; glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); glColor4f(0.0, 0.5, 1.0, 1.0); // the coordinates of the rectangle are // myRect.x, myRect.y, myRect.width, myRect.height // Do I need to use a matrix to translate the currentPosition of the // 3-D model so it is drawn within myRect? //glOrthof(-160.0f, 160.0f, -240.0f, 240.0f, -1.0f, 1.0f); [plane drawSelf]; }

  • Profiler tool for web service

    - by Rotem
    Hi, I need a profiler that is able to measure performance of web service execition. Our application has several layers and ideally I would like to be able to dive into each web service request and see how much time was spent in each layer (server, sql server, etc...) Is there a tool that can help detect where are the bottlenecks ? Is that something that can be done using VS Team System Test Edition ?

  • Which Cassandra API provides the highest level of abstraction?

    - by knorv
    There are a lot of Cassandra API:s available and usually the programming language preference determines the choice of API. However, if we take the programming language component out of the equation, what Cassandra API provides the highest level of abstraction? Definition of "level of abstraction" in this context: An API providing a lot of extra goodies such as index handling, etc would be considered being at a higher abstraction layer than a bare bones "close to Thrift" API.

  • HTTP triggers for Postgres

    - by HeineyBehinds
    I'm trying to write a Postgres trigger such that when a configuration table is updated, a backend component is notified and can handle the change. I know that Oracle has the concept of a web/HTTP trigger, where you can execute an HTTP GET from the Oracle instance itself to a URL that can then handle the request at the application layer. I'm wondering if Postgres (v. 9.0.5) has the same feature, or comes with anything similar (and, subsequently, how to set it up/configure it)?

  • Manually Increasing the Amount of CPU a Java Application Uses

    - by SkylineAddict
    I've just made a program with Eclipse that takes a really long time to execute. It's taking even longer because it's loading my CPU to 25% only (I'm assuming that is because I'm using a quad-core and the program is only using one core). Is there any way to make the program use all 4 cores to max it out? Java is supposed to be natively multi-threaded, so I don't understand why it would only use 25%.

  • CMS Layout Problem

    - by Sebi
    I made a small page (http://www.ovlu.li) using CMS Made Simple (http://www.cmsmadesimple.org/). It looks more or less okay in all browser, but the problem is, if a resize the window to a smaller size, sometimes the layout of the subnavigation layer is destroyed. Instead of getting smaller, all the elements are ordered more or less randomly. Any hints why?
