  • Popular open source projects using Zend Framework

    - by Alexander
    Hello, I am trying to find any open source project based on Zend Framework. Something well written and as popular as Wordpress or Drupal to see actual benefits of ZF as well as possibly use it as an example. The only 'showcase' I managed to find is http://framework.zend.com/wiki/pages/viewpage.action?pageId=14134. But this list looks confusing as for the 'official' PHP framework. The same is about ZF statistics by numbers (http://framework.zend.com/about/numbers) - 10 million downloads against 400 actual projects which is less than 500 examples in the user guide... Also Yahoo chose Symfony for their bookmarks service not ZF... Am I missing something? Thank you!

  • MacOSX: OSAtomic vs OSAtomicBarrier

    - by anon
    For the functions here: #include <libkern/OSAtomic.h> there are OSAtomic and OSAtomicBarrier versions. However, the documentation does not show sample code for: When is it safe to use just OSAtomic, without the OSAtomicBarrier version When is it that OSAtomic would be unsafe, but OSAtomiBarrier would be safe. Can anyone provide explainations + sample codes? [Random ramblings of "your opinion" without actual code is useless. Readers: please down vote such answers; and vigrously upvote answers with actual code.] [C/C++ code preferred; Assembly okay too.]

  • Pure virtual destructor in interface

    - by ALOR
    Hello all. Here is my problem. I'm making C++ dll, which extensively relies on instance object exports. So i return my actual instances as a pointers to interface through some exported factory method. Interfaces i use are purely virtual, to avoid linking problame. So i need a pure virtual destructor too, and i implemented one (with empty body, as i googled it). All compiles perfectly well, except... I can't see, if the actual destructors are called or not - because when i added some std::cout << "hello destructor"; i never get to see it. I have some explicit "delete obj", that's not the problem. Am i missing something? Is there another way to delete my object through interface?

  • What's the most scalable way to handle somewhat large file uploads in a Python webapp?

    - by Jason Baker
    We have a web application that takes file uploads for some parts. The file uploads aren't terribly big (mostly word documents and such), but they're much larger than your typical web request and they tend to tie up our threaded servers (zope 2 servers running behind an Apache proxy). I'm mostly in the brainstorming phase right now and trying to figure out a general technique to use. Some ideas I have are: Using a python asynchronous server like tornado or diesel or gunicorn. Writing something in twisted to handle it. Just using nginx to handle the actual file uploads. It's surprisingly difficult to find information on which approach I should be taking. I'm sure there are plenty of details that would be needed to make an actual decision, but I'm more worried about figuring out how to make this decision than anything else. Can anyone give me some advice about how to proceed with this?

  • Unit testing class in a web service in .net

    - by Dan Bailiff
    After some digging here, I took the advice in this thread: http://stackoverflow.com/questions/371961/how-to-unit-test-c-web-service-with-visual-studio-2008 I've created a separate class and my web service class is just a wrapper for that one. The problem is that when I try to create a unit test project in VS2008, it insists on creating a unit test that acts like I'm testing the web service calls instead of the class I specified. I can't get to the class I'm trying to test. I have a web service "subscription_api.asmx". The code behind is "subscription_api.cs" which contains the web method wrapper calls to the real code at "subscription.cs". I would expect to be able to do the following: [TestMethod()] public void GetSystemStatusTest() { subscription sub = new subscription(); XmlNode node = sub.GetSystemStatusTest(); Assert.IsNotNull(node); } But instead I get this mess which is autogenerated from VS'08: /// <summary> ///A test for GetSystemStatus ///</summary> // TODO: Ensure that the UrlToTest attribute specifies a URL to an ASP.NET page (for example, // http://.../Default.aspx). This is necessary for the unit test to be executed on the web server, // whether you are testing a page, web service, or a WCF service. [TestMethod()] [HostType("ASP.NET")] [AspNetDevelopmentServerHost("C:\\CVSROOT\\rnr\\pro\\product\\wms\\ss\\subscription_api", "/subscription_api")] [UrlToTest("http://localhost/subscription_api")] public void GetSystemStatusTest() { subscription_Accessor target = new subscription_Accessor(); // TODO: Initialize to an appropriate value XmlNode expected = null; // TODO: Initialize to an appropriate value XmlNode actual; actual = target.GetSystemStatus(); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } Additionally, there is a "subscription_api.accessor" in the Test References folder. When I try this: [TestMethod()] public void GetSystemStatusTest2() { subscription_Accessor sub = new subscription_Accessor(); XmlNode node = sub.GetSystemStatus(); Assert.IsNotNull(node); } I get an error: Test method subscription_api.Test.subscriptionTest.GetSystemStatusTest2 threw exception: System.TypeInitializationException: The type initializer for 'subscription_Accessor' threw an exception. ---> System.ArgumentNullException: Value cannot be null. I'm really new to unit testing and feel lost. How can I create a unit test just for my subscription class in "subscription.cs" without testing the web service? Am I limited to testing within the same project (I hope not)? Do I have to put the target class in its own project outside of the web service project?

  • Python doctests / sphinx : style guide, how to use those and have a readable code ?

    - by Sébastien Piquemal
    Hi ! I love doctests, it is the only testing framwork I use, because it is so quick to write, and because used with sphinx it makes such great documentations with almost no effort... However, very often, I end-up doing things like this : """ Descriptions ============= bla bla bla ... >>> test 1 bla bla bla + tests tests tests * 200 lines = poor readability of the actual code """ What I mean is that I put all my tests with documentation explanations on the top of the module, so you have to scroll stupidly to find the actual code, and this is quite ugly (in my opinion). However, I think that the doctests should still stay in the module, because you should be able to read them while reading the source code. So here comes my question : sphinx/doctests lovers, how do you organize your doctests, such as the code readability doesn't suffer ?

  • How can I make this Dictionary TryGetValue code more readable?

    - by mafutrct
    I'd like to test if an id was not yet known or, if it is known, if the associated value has changed. I'm currently using code similar to this, but it is hard to understand for those not familiar with the pattern. Can you think of a way to make it more readable while keeping it short in LOC? string id; string actual; string stored; if (!someDictionary.TryGetValue (id, out stored) || stored != actual) { // id not known yet or associated value changed. }

  • Question regarding the use of iframes in Safari and Chrome's startup pages

    - by Wesley
    If you have ever used a new release of either Chrome or Safari, you know that when you add a new tab, the default screen is a grid like setup with your most favorite links sitting there waiting to be clicked on. What makes it even nicer is the graphical interface, with actual pictures of the websites they are representing. I am looking to do something similar, how is it done? Are they simply iframes? iframes set with css? If anyone has any knowledge about the actual implementation of this seemingly simple festure, please share!! Thanks

  • getting real link from rss feed link

    - by pfunc
    I am experimenting with scraping certain pages from an RSS feed using curl and php. The page scraping was working fine when I was just using actual links, not links from the rss feeds. However, I realize now that links in rss feeds are usually just redirects to the actual page (at least this is what it seems like). Because now when I scrape a page with the rss link, it doesn't actually get the information I am looking for. Has anyone encountered this and know of a workaround. Is there anyway to see where the rss link is redirecting to and capturing that value?

  • Tool to measure Render time

    - by Noob
    Hi Folks, Is there a tool out there to measure the actual Render time of an element(s) on a page? I don't mean download time of the resources, but the actual time the browser took to render something. I know that this time would vary based on factors on the client machine, but would still be very handy in knowing what the rendering engine takes a while to load. I would imagine this should be a useful utility since web apps are becoming pretty client heavy now. Any thoughts?

  • How to calculate the touch location with convertToWorldSpace?

    - by Paul
    i would like to convert the touch location as a world coordinate in my tile game. With this code, i clicked on the right of the screen (so that my character walks in the tiled game, and the background goes slowly to the left) : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL: location]; CGPoint test = [self convertToWorldSpace:location]; CCLOG(@"test : %.2g", test.x); The test log gives me : 50, 72, 1e+02, 2.6e+02, 4.2e+02, (and then goes down) 3.2e+02, 9.5, -1.9e+02, etc. Does anyone know why? I would like to calculate the "real" coordinate of the touch, so that i know when the character has to keep going (click on the right of its actual position) or if he has to turn and go backwards. (click on the left of its actual position) Thanks for your help

  • WCF interoperability with WSDL proxy and performance consideration advise.

    - by user194917
    I'm essentially writing a broker service. The requirement is that I write an API that acts as an intermediary broker between our in-house developed services and a 3rd party provided API. The intention being that my API abstract the actual communication with the 3rd party API from our internal systems. The architect on the project chose WCF as the communication framework. The problem is that 70 percent of our subscriber applications are written in .Net 2 and as such have no access to the class libraries required to implement a WCF proxy. The end result being that our proxy classes are loosely based on the code auto generated by the WSDL tool as opposed to the SvcUtil tool. My question is, although I have no issues implementing the required proxy classes using basicHttp as the actual binding and using the WSDL tool, are there any special considerations that I need to take into account in this scenario? I.E proxy optimizations and the like. Thanks in advance.

  • Trying to draw textured triangles on device fails, but the emulator works. Why?

    - by Dinedal
    I have a series of OpenGL-ES calls that properly render a triangle and texture it with alpha blending on the emulator (2.0.1). When I fire up the same code on an actual device (Droid 2.0.1), all I get are white squares. This suggests to me that the textures aren't loading, but I can't figure out why they aren't loading. All of my textures are 32-bit PNGs with alpha channels, under res/raw so they aren't optimized per the sdk docs. Here's how I am loading my textures: private void loadGLTexture(GL10 gl, Context context, int reasource_id, int texture_id) { //Get the texture from the Android resource directory Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), reasource_id, sBitmapOptions); //Generate one texture pointer... gl.glGenTextures(1, textures, texture_id); //...and bind it to our array gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[texture_id]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); //Different possible texture parameters, e.g. GL10.GL_CLAMP_TO_EDGE gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT); //Use the Android GLUtils to specify a two-dimensional texture image from our bitmap GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); //Clean up bitmap.recycle(); } Here's how I am rendering the texture: //Clear gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); //Enable vertex buffer gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer); //Push transformation matrix gl.glPushMatrix(); //Transformation matrices gl.glTranslatef(x, y, 0.0f); gl.glScalef(scalefactor, scalefactor, 0.0f); gl.glColor4f(1.0f,1.0f,1.0f,1.0f); //Bind the texture gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[textureid]); //Draw the vertices as triangles gl.glDrawElements(GL10.GL_TRIANGLES, indices.length, GL10.GL_UNSIGNED_BYTE, indexBuffer); //Pop the matrix back to where we left it gl.glPopMatrix(); //Disable the client state before leaving gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); And here are the options I have enabled: gl.glShadeModel(GL10.GL_SMOOTH); //Enable Smooth Shading gl.glEnable(GL10.GL_DEPTH_TEST); //Enables Depth Testing gl.glDepthFunc(GL10.GL_LEQUAL); //The Type Of Depth Testing To Do gl.glEnable(GL10.GL_TEXTURE_2D); gl.glEnable(GL10.GL_BLEND); gl.glBlendFunc(GL10.GL_SRC_ALPHA,GL10.GL_ONE_MINUS_SRC_ALPHA); Edit: I just tried supplying a BitmapOptions to the BitmapFactory.decodeResource() call, but this doesn't seem to fix the issue, despite manually setting the same preferredconfig, density, and targetdensity. Edit2: As requested, here is a screenshot of the emulator working. The underlaying triangles are shown with a circle texture rendered onto it, the transparency is working because you can see the black background. Here is a shot of what the droid does with the exact same code on it: Edit3: Here are my BitmapOptions, updated the call above with how I am now calling the BitmapFactory, still the same results as below: sBitmapOptions.inPreferredConfig = Bitmap.Config.RGB_565; sBitmapOptions.inDensity = 160; sBitmapOptions.inTargetDensity = 160; sBitmapOptions.inScreenDensity = 160; sBitmapOptions.inDither = false; sBitmapOptions.inSampleSize = 1; sBitmapOptions.inScaled = false; Here are my vertices, texture coords, and indices: /** The initial vertex definition */ private static final float vertices[] = { -1.0f, -1.0f, 0.0f, 1.0f, -1.0f, 0.0f, -1.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f }; /** The initial texture coordinates (u, v) */ private static final float texture[] = { //Mapping coordinates for the vertices 0.0f, 1.0f, 1.0f, 1.0f, 0.0f, 0.0f, 1.0f, 0.0f }; /** The initial indices definition */ private static final byte indices[] = { //Faces definition 0,1,3, 0,3,2 }; Is there anyway to dump the contents of the texture once it's been loaded into OpenGL ES? Maybe I can compare the emulator's loaded texture with the actual device's loaded texture? I did try with a different texture (the default android icon) and again, it works fine for the emulator but fails to render on the actual phone. Edit4: Tried switching around when I do texture loading. No luck. Tried using a constant offset of 0 to glGenTextures, no change. Is there something that I'm using that the emulator supports that the actual phone does not? Edit5: Per Ryan below, I resized my texture from 200x200 to 256x256, and the issue was NOT resolved. Edit: As requested, added the calls to glVertexPointer and glTexCoordPointer above. Also, here is the initialization of vertexBuffer, textureBuffer, and indexBuffer: ByteBuffer byteBuf = ByteBuffer.allocateDirect(vertices.length * 4); byteBuf.order(ByteOrder.nativeOrder()); vertexBuffer = byteBuf.asFloatBuffer(); vertexBuffer.put(vertices); vertexBuffer.position(0); byteBuf = ByteBuffer.allocateDirect(texture.length * 4); byteBuf.order(ByteOrder.nativeOrder()); textureBuffer = byteBuf.asFloatBuffer(); textureBuffer.put(texture); textureBuffer.position(0); indexBuffer = ByteBuffer.allocateDirect(indices.length); indexBuffer.put(indices); indexBuffer.position(0); loadGLTextures(gl, this.context);

  • Location accuracy of Google Analytics for Android

    - by BadCash
    When testing Google Analytics (version 2) for an Android project, I noticed that the Real Time map shows my location to be about 200 miles from my actual location. I'm running my project on a physical device, which leads me to believe that Google Analytics doesn't actually send any location information, but rather gets it from the phones IP address when the data is sent to Googles server. Is there any way to alter this behavior and provide my own location data using getLastKnownLocation() for example? Sending it as an actual Label/Action string would of course work, but that means I can't use Google Analytics fancy map feature to view where my users are coming from.

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • string manipulations in C

    - by Vivek27
    Following are some basic questions that I have with respect to strings in C. If string literals are stored in read-only data segment and cannot be changed after initialisation, then what is the difference between the following two initialisations. char *string = "Hello world"; const char *string = "Hello world"; When we dynamically allocate memory for strings, I see the following allocation is capable enough to hold a string of arbitary length.Though this allocation work, I undersand/beleive that it is always good practice to allocate the actual size of actual string rather than the size of data type.Please guide on proper usage of dynamic allocation for strings. char *string = (char *)malloc(sizeof(char));

  • Best Practice for CouchDB Document Versioning

    - by Groundwater
    Following my question here I am exmploring ideas for a generic approach to document versioning in CouchDB. While I imagine there may be no canonical approach, I had the following idea and am looking for feedback. I would like to maintain readable document ids as much as possible, so a document existing at /document1 would contain a pointer document to all existing versions on the system. The actual revision documents would be at something like /document1/308ef032a3801a where 308ef032a3801a is some random number or hash. Example The pointer document { "_id" : "document1", "versions" : [ "document1/308ef032a3801a" ] } The version document { "_id" : "document1/308ef032a3801a", ... actual content }

  • How to pass an int value on UIButton click inside UITableView

    - by Toran Billups
    So I have a view controller with a single UITableView that shows a string to the user. But I needed a way to have the user select this object by id using a normal UIButton so I added it as a subview and the click event works as expected. The issue is this - how can I pass an int value to this click event? I've tried using attributes of the button like button.tag or button.accessibilityhint without much success. How do the professionals pass an int value like this? Also it's important that I can get the actual [x intValue] from the int later in the process. A while back I thought I could do this with a simple NSLog(@"the actual selected hat was %d", [obj.idValue intValue]); But this doesn't appear to work (any idea how I can pull the actual int value directly from the variable?). The working code I have is below - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if ([self.hats count] > 0) { Hat* obj = [self.hats objectAtIndex: [indexPath row]]; NSMutableString* fullName = [[NSMutableString alloc] init]; [fullName appendFormat:@"%@", obj.name]; [fullName appendFormat:@" %@", obj.type]; cell.textLabel.text = fullName; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; //add the button to subview hack UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 5, 50, 25); [button setTitle:@"Select" forState:UIControlStateNormal]; button.backgroundColor = [UIColor clearColor]; button.adjustsImageWhenHighlighted = YES; button.tag = obj.idValue; //this is my current hack to add the id but no dice :( [button addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside]; [cell.contentView addSubview:button]; //hack } return cell; } - (void)action:(id)sender { int* hatId = ((UIButton *)sender).tag; //try to pull the id value I added above ... //do something w/ the hatId }

  • C++ Word-Number to int

    - by Andrew
    I'm developing a program that makes basic calculations using words instead of numbers. E.g. five + two would output seven. The program becomes more complex, taking input such as two_hundred_one + five_thousand_six (201 + 5006) Through operator overloading methods, I split each number and assign it to it's own array index. two would be [0], hundred is [1], and one is [2]. Then the array recycles for 5006. My problem is, to perform the actual calculation, I need to convert the words stored in the array to actual integers. I have const string arrays such as this as a library of the words: const string units[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; const string teens[] = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; const string tens[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; If my 'token' array has stored in it two hundred one in index 0, 1, and 2, I'm not sure what the best way to convert these to ints would involve.
