• NSInvocationOperation and main thread

  - by kpower

  Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

• WCF Project vs. A folder in the existing website project?

  - by user193189

  What way makes the most sense? I have a ASP.NET app... and maybe a Silverlight app in the future.. I want both to talk to web services.. At first, I like have the WCF project be by it self for the seperation.. But then I thought.. What is the point since I can just as easily have a 'WEBSERVICES' folder that contains all the .svc files and code in the EXISTING website project. ... Atleast that way.. deploying to a remote host will be a little easier since everything is in one project.. any other considerations ?

• In C# should I use uint or int for values that are never supposed to be negative?

  - by Hamish Grubijan

  Suppose that the MaxValue of (roughly :) ) 2^31 vs 2^32 does not matter. On one hand, using uint seems nice because it is self-explanatory, it indicates (and promises?) that some value may never be negative. However, int is more common, and a cast is often inconvenient. One can just use int and always supplement it with code contracts (everyone has moved to .Net 4.0 by now, right?) Standard libraries do use int for Length and Size properties, even though those should never be negative. So, is it obvious to you that int is better than uint most of the time, or is it more complicated? Please ask questions if you find that this question is not clearly stated. Thanks.

• willAnimateSecondHalfOfRotationFromInterfaceOrientation not called in root view controller

  - by pJosh

  I have created the one rootviewcontroller , and then make that geosensitive by writing - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } In rootviewcontroller willAnimateSecondHalfOfRotationFromInterfaceOrientation method is called and images are resizing. I also have some views on it, but when I rotate the screen the view will be rotate but the images are not resizing though I have used the same -(void)willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration { UIInterfaceOrientation toOrientation = self.interfaceOrientation; } method but it cannot called. So, what can I do? Please help me.

• How to determine the pat of the current web site

  - by Velika2

  I wanted to create a function which would return the path of the current web site. This is what I thought was working while running in the IDE: Public Shared Function WebsiteAbsoluteBaseUrl() As String Dim RequestObject As System.Web.HttpRequest = HttpContext.Current.Request Return "http://" & RequestObject.Url.Host & ":" & _ RequestObject.Url.Port & "/" & _ RequestObject.Url.Segments(1) End Function Does this seem like it should work? Is there a more straight forward way?

• How do I build mDNSResponder?

  - by Alex

  I have tried checking out the mDNSResponder source from Apple's SVN host, with the thought of compiling it and tweaking it. This failed miserably. Here is the last line of the output of cd trunk SRCROOT=. make I get the same error for several tags in the SVN tree, so I'm not sure if there is something on my end wrong? The following build commands failed: mDNSResponder: CompileC mDNSResponder.build/mDNSResponder.build/Objects-normal/i386/mDNSMacOSX.o /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSMacOSX.c normal i386 c com.apple.compilers.gcc.4_2 PhaseScriptExecution "Run Script" /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSResponder.build/mDNSResponder.build/Script-D284BE6C0ADD80740027CCDF.sh mDNSResponder debug: CompileC "mDNSResponder.build/mDNSResponder debug.build/Objects-normal/i386/mDNSMacOSX.o" /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSMacOSX.c normal i386 c com.apple.compilers.gcc.4_2 Build Some: PhaseScriptExecution "Run Script" "/Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSResponder.build/Development/Build Some.build/Script-FF045B6A0C7E4AA600448140.sh" (4 failures)

• Using an IBAction method when it is not called from an action?

  - by cannyboy

  Are there any issues when using IBAction when it is not actually called from a user's action? If you have an action like -(IBAction)sayHello:(id)sender; You can call it from within your class like: [self sayHello:@"x"] The @"x" doesn't do anything, it just fills in for the sender. You can actually create an IBAction method without (id)sender -(IBAction)sayHello; and call it from both user's actions and from within the code, but then you won't get any useful sender info from the interface. What's the 'correct' way of filling in for the sender, when calling from the code? And can you create sender info to send when it's called from within the code? Just trying to figure it out.

  - by Nacari

  I have been trying to get a simple spider to run with scrapy, but keep getting the error: Could not find spider for domain:stackexchange.com when I run the code with the expression scrapy-ctl.py crawl stackexchange.com. The spider is as follow: from scrapy.spider import BaseSpider from __future__ import absolute_import class StackExchangeSpider(BaseSpider): domain_name = "stackexchange.com" start_urls = [ "http://www.stackexchange.com/", ] def parse(self, response): filename = response.url.split("/")[-2] open(filename, 'wb').write(response.body) SPIDER = StackExchangeSpider()` Another person posted almost the exact same problem months ago but did not say how they fixed it, http://stackoverflow.com/questions/1806990/scrapy-spider-is-not-working I have been following the turtorial exactly at http://doc.scrapy.org/intro/tutorial.html, and cannot figure out why it is not working.

• alias_attribute and creating and method with the original attribute name causes a loop

  - by Tiago

  Im trying to dynamically create a method chain in one attribute in my model. By now I have this function: def create_filtered_attribute(attribute_name) alias_attribute "#{attribute_name}_without_filter", attribute_name define_method "#{attribute_name}" do filter_words(self.send("#{attribute_name}_without_filter")) end end so I receive a string with the attribute name, alias it for '*_without_filter*' (alias_method or alias_method_chain fails here, because the attribute isnt there when the class is created), and I create a new method with the attribute name, where I filter its contents. But somehow, when I call *"#{attribute_name}_without_filter"* it calls my new method (i think because the alias_attribute some how), and the program goes into a stack loop. Can someone please enlighten me on this.

• Django: tinyMCE and cross site javascript

  - by pistacchio

  Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

• Adobe Flex, loading a remote swf

  - by JonoB

  I have a flex app running on my server. I have had a request from some clients to have the swf loaded on their server, so that their customers dont have to be transferred to my server to login; i.e. from the user's point of view it looks like they are logging in from theirsite.com instead of mysite.com I tried something really simple, and that was to give them a html wrapper to host on their site. The only modification that I made was to change the "src" var to: "src", "https://www.mysite.com/app/myapp.swf" and embed src="https://www.mysite.com/app/myapp.swf" To my surprise, this worked perfectly. And best of all, the service calls still seem to come from mysite.com, so I dont have to bother with modifying the crossdomain.xml file. All good it seems. Are there any issues or downsides to the above that I should be aware of?

• Static Access To Multiple Instance Variable

  - by Qua

  I have a singleton instance that is referenced throughout the project which works like a charm. It saves me the trouble from having to pass around an instance of the object to every little class in the project. However, now I need to manage multiple instances of the previous setup, which means that the singleton pattern breaks since each instance would need it's own singleton instance. What options are there to still maintain static access to the singleton? To be more specific, we have our game engine and several components and plugins reference the engine through a static property. Now our server needs to host multiple game instances each having their own engine, which means that on the server side the singleton pattern breaks. I'm trying to avoid all the classes having the engine in the constructor.

• Tell The Program What To Do When No Save Data Is Found NSUserDefaults, iPhone

  - by Stumf

  Hello all, I have saved data which was saved using NSUserDefaults. I was under the impression that if there was nothing saved to the key already (first time app is run) it would default to 0. This however doesn't seem to be the case. Here is what I have: To save: - (void)viewWillDisappear:(BOOL)animated { [[NSUserDefaults standardUserDefaults] setInteger:setbatteryHealthCalculated forKey:@"healthValue"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To load: - (void) viewWillAppear:(BOOL)animated { NSInteger setbatteryHealthCalculated = [[NSUserDefaults standardUserDefaults] integerForKey:@"healthValue"]; } To check for save value: - (IBAction)check{ NSInteger setbatteryHealthCalculated = [[NSUserDefaults standardUserDefaults] integerForKey:@"healthValue"]; if (setbatteryHealthCalculated = 0) { [self performSelector:@selector(displayAlert) withObject:nil]; }

• UINavigationController and memory management

  - by Dan Ray

  - (void)launchSearch { EventsSearchViewController *searchController = [[EventsSearchViewController alloc] initWithNibName:@"EventsSearchView" bundle:nil]; [self.navigationController pushViewController:searchController animated:YES]; //[searchController release]; } Notice the [searchController release] is commented out. I've understood that pushing searchController onto the navigation controller retains it, and I should release it from my code. I did just alloc/init it, after all, and if I don't free it, it'll leak. With that line commented out, navigation works great. With it NOT commented out, I can navigate INTO this view okay, but coming back UP a level crashes with a *** -[CFArray release]: message sent to deallocated instance 0x443a9e0 error. What's happening here? Is the NavigationController releasing it for me somehow when it goes out of view? The boilerplate that comes on a UINavigationController template in XCode has the newly-pushed controller getting released. But when I do it, it fails.

• Best practices for using memcached in Rails?

  - by Matt

  Hello everybody, as database transcations in our app are getting more and more time consuming, we have started to use memcached to reduce the amount of queries passed to MySQL. All in all, it works fine and really saves a lot of time. But as caching was "silently appearing" as a workaround to give the app more juice, a lot of our models now contain code like this: def self.all_cached Rails.cache.fetch('object_name') { find( :all, :include => [associations]) } end This is getting more and more a pain as filling and flushing the cache happens in several classes accross the application. Now, I was wondering if there was a better way to abstract memcached logic to make it more powerful and easy to use across all needed models? I was thinking about having some kind of memcached-module which is included in all needed modules. But before playing around, I thought: Let's ask experts first :-) Thanks Matt

• Windows secure pinned website tile

  - by Stijn de Voogd

  I'm currently working on a pinned website tile for my website and instead of using a static XML file i'm linking the tile to a web api that returns user specific XML. My question is: Is it possible to secure this tile so that a user needs to be logged in before the data loads? The pinned website livetile doesn't send any security request headers/ cookies: - Http: Request, GET /v1/livetile/firsttile Command: GET + URI: /v1/livetile/firsttile ProtocolVersion: HTTP/1.1 UserAgent: Microsoft-WNS/6.3 Host: 192.168.14.109:2089 Cache-Control: no-cache HeaderEnd: CRLF Sidenote: Notice how it's not even sending an accept header even though it only wants xml.

• Addressing a memory leak stops my UI from showing iphone

  - by dubbeat

  Hi I've being getting a memory leak warning with a UITabbarcontroller. If I release the tabbarcontroller the warning goes away but the tabbar will not show any content. If I debug the app with the warning still in it the app runs but will crash after a couple of minutes UITabBarController *tabBarController = [[UITabBarController alloc] init]; tabBarController.view.frame = CGRectMake(0, 0, 320, 460); tabBarController.viewControllers=localControllersArray; // Clean up objects we don't need anymore [promoTabOptionHome release]; [promoTabOptionInfo release]; [promoTabOptionEvents release]; [promoTabOptionBuy release]; [localControllersArray release]; // Finally, add the tab controller view to the parent view [self.view addSubview:tabBarController.view]; //[tabBarController release]; commenting out this line removes the warning but results in no content being shown

• Good articles to read on SSL and HTTPS?

  - by Igor Romanov

  I had a problem with accepting invalid SSL certificate in my iPhone program. That problem is solved now, however I came to understanding that I have very abstract idea on how exactly the whole thing is working: how web browser is verifying that received certificate is really for host it communicates to and not faked by same party in the middle? if browser talks to some 3rd party (CA?) to do certificate check? and many other questions... Would someone please recommend good source of information with in-depth enough description of how all parts click together?

• Classic ASP, ASP.NET, IFrames and response.redirect issue....

  - by Abdullah Ahmed

  A client has an asp page with an iframe. The Iframe loads an asp.net page inside the asp classic page. The ASP.NET page is responsible for connecting to a webservice, displaying some data, and then when the user clicks a button it does a response.redirect another classic asp page. Since the asp.net page is in an iframe, the asp page loads inside the iframe when ideally it should be taking over the entire page. I have tried putting javascript in the final asp page to break out of iframes but it does not seem to fire. I tried doing onClientCLick() on the asp.net page and making it break out of the iframe using the following javascript top.location = self.location.href But since that sets the location it seems to refresh the page , breaks out of the iframe but does not fire the serverside onclick event which would then perform the backend calculations and do response.redirect. Any ideas on how I can make sure that the final asp page does not appear inside the iframe and breaks out of it ?

• Querying current number of touches on screen without using events on iPhone

  - by nikhil

  I have an application that starts playing a sound when user touches the uiview and changing to different tones as the user slides the finger on the screen. The sound stops when the user lifts the finger. I am using the touchesBegan, Moved and Ended Events for this. My problem is touches Ended (and/or cancelled) is sometimes not fired properly and the sound keeps playing even after the finger is lifted from screen. So as a workaround I would like to implement a timer that would check for the number of touches on the screen and if it is zero it will check and stop the audioplayer if playing. I have been searching for some code that could get me the number of touches like UITouch *touches=[self getAllTouchesonScreen]; or something :)

• How to cache and store objects and set an expire policy in android?

  - by virsir

  I have an app fetch data from internet, for better performance and bandwidth, I need to implement a cache layer. There are two different data coming from the internet, one is changing every one hour and another one does not change basically. So for the first type of data, I need to implement an expire policy to make it self deleted after it was created for 1 hour, and when user request that data, I will check the storage first and then goto internet if nothing found. I thought about using a SharedPrefrence or SQLDatabase to store the json data or serialized object string. My question is: 1) What should I use, SharedPrefrence or SQLDatabase or anything else, a piece of data is not big but there are maybe many instances of that data. 2) How to implement that expire system.

• One off errors with NSLog and NSString stringWithFormat

  - by David Liu

  Does anyone know why there would be one-off errors with NSLog and NSString? It works fine in 99% of my program, but for some reason this error appears in one of my model's description method: Example code: localFileId = 7; type = 2; localId = 5; NSLog(@"CachedFile localId=%d, 2=%d, localFileId=%d, type=%d, path=%@", localId, 2, localFileId, type, self.path); Example Result: CachedFile localId=5, 2=0, localFileId=2, type=7, path=(null) Notice the "0" that gets inserted in there, where it should be "2=2". This happens with NSString stringWithFormat as well.

• What is the main purpose and sense to have staging server the same as production?

  - by truthseeker

  Hi, In our company we have staging and production servers. I'm trying to have them in state 1:1 after latest release. We've got web application running on several host and many instances of it. The issue is that I am an advocate of having the same architecture (structure) of web applications on staging and production servers to easily test new features and avoid creating of new bugs with new releases. But not everyone agree with me, and for them is not a such big deal to have different connection between staging application instances. Even maybe to have more application and connections between application on staging than on production server. I would like to ask about pros and cons of such an approach? I mean some good points to agree with me, or some bad why maybe i don't have right. Some examples of consequences and so forth.

• How's my pygame code?

  - by Isaiah

  I'm still getting the hang of lots of things and thought I should post some code I made with pygame and get some feedback^^. I posted code here: http://urlvars.com/code/snippet/39272/my-bouncing-program http://urlvars.com/code/snippet/39273/my-bouncing-program-classes There's tome things that I implemented that I'm not using yet I just realized like a timer at the bottom of the main while loop. If my code isn't readable, I'm sorry, I'm self taught and this is the first code I've ever posted anywhere. By the way I made some variables that take the screensize and half it to find a point to spit out the squares, but when I try to use it, it makes a weird effect :/ Try switching the list i have in the newbyte() function with the halfScreen variable and see it freak out o.O thank you
