• ASP.NET Membership

  - by Gary McGill

  I'd like to use the ASP.NET membership provider in the following (low-security) scenario... My company will create and administer user accounts on behalf of our clients. These accounts will likely be shared amongst several people in the client company (is that a problem?). There will be 2 types of users (2 roles): client and administrator. Administrators are the people within my company that will have special privileges to create client user accounts, etc. Clients will not be able to self-register. They also won't get to choose their own password, and they should not be able to change their password either, since that will just create confusion where several people are sharing the same account. My internal users (admins) will set the password for each client. Here's the bit I'm struggling with: if a client phones up and asks to be reminded of their password, how can my admin users find out what the password is? Can I configure the provider to store the password in clear text (or other recoverable form), and if so can I get at the password through the .NET API? As I said at the outset, this is a low-security application, and so I plan simply to show the password in the (internal) web page where I have a list of all users.

• Can I include a NSUserDefault password test in AppDelegate to load a loginView?

  - by Michael Robinson

  I have a name and password in NSUserDefaults for login. I want to place a test in my AppDelegate.m class to test for presence and load a login/signup loginView.xib modally if there is no password or name stored in the app. Here is the pulling of the defaults: -(void)refreshFields { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; usernameLabel.text = [defaults objectForKey:kUsernameKey]; passwordLabel.text = [defaults objectForKey:kPasswordKey]; Here is the tabcontroller loading part: - (void)applicationDidFinishLaunching:(UIApplication *)application { firstTab = [[FirstTab alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController:firstTab]; [firstTab release]; secondTab = // EDITED FOR SPACE thirdTab = // EDITED FOR SPACE tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigationController, secondNavigationController, thirdNavigationController, nil]; [window addSubview:tabBarController.view]; [firstNavigationController release]; [secondNavigationController release]; [thirdNavigationController release]; [self logout]; [window makeKeyAndVisible]; Here is where the loginView.xib loads automatically: - (void)logout { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; } I want to replace the above autoload with a test similar to below (that works) using IF-ELSE - (void)logout { if ([usernameLabel.text length] == 0 || [passwordLabel.text length] == 0) { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; }else { [window addSubview:tabBarController.view];} Thanks in advance, I'm totally lost on this.

• AVAudioRecorder Won't Record On Device

  - by Dyldo42

  This is my method: -(void) playOrRecord:(UIButton *)sender { if (playBool == YES) { NSError *error = nil; NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"]; NSURL *fileUrl = [NSURL fileURLWithPath:filePath]; AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileUrl error:&error]; [player setNumberOfLoops:0]; [player play]; } else if (playBool == NO) { if ([recorder isRecording]) { [recorder stop]; [nowRecording setImage:[UIImage imageNamed:@"NormalNormal.png"] forState:UIControlStateNormal]; [nowRecording setImage:[UIImage imageNamed:@"NormalSelected.png"] forState:UIControlStateSelected]; } if (nowRecording == sender) { nowRecording = nil; return; } nowRecording = sender; NSError *error = nil; NSString *filePath = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat: @"%d", [sender tag]] ofType:@"caf"]; NSURL *fileUrl = [NSURL fileURLWithPath:filePath]; [sender setImage:[UIImage imageNamed:@"RecordingNormal.png"] forState:UIControlStateNormal]; [sender setImage:[UIImage imageNamed:@"RecordingSelected.png"] forState:UIControlStateSelected]; recorder = [[AVAudioRecorder alloc] initWithURL:fileUrl settings:recordSettings error:&error]; [recorder record]; } } Most of it is self explanatory; playBool is a BOOL that is YES when it is in play mode. Everything works in the simulator however, when I run it on a device, [recorder record] returns NO. Does anyone have a clue as to why this is happening?

• Scrolling with two fingers with a UIScrollView

  - by Craig

  I have an app where my main view accepts both touchesBegan and touchesMoved, and therefore takes in single finger touches, and drags. I want to implement a UIScrollView, and I have it working, but it overrides the drags, and therefore my contentView never receives them. I'd like to implement a UIScrollview, where a two finger drag indicates a scroll, and a one finger drag event gets passed to my content view, so it performs normally. Do I need create my own subclass of UIScrollView? Here's my code from my appDelegate where I implement the UIScrollView. @implementation MusicGridAppDelegate @synthesize window; @synthesize viewController; @synthesize scrollView; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch //[application setStatusBarHidden:YES animated:NO]; //[window addSubview:viewController.view]; scrollView.contentSize = CGSizeMake(720, 480); scrollView.showsHorizontalScrollIndicator = YES; scrollView.showsVerticalScrollIndicator = YES; scrollView.delegate = self; [scrollView addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [scrollView release]; [window release]; [super dealloc]; }

• Clipped UITextField with UITextFieldAlignmentRight

  - by Typeoneerror

  Got a small problem with UITextField. I have a simple UITextField and when I set the textAlignment property to "right", it gets clipped by 1-2 pixels. It looks shite so I'm hoping someone has an idea of how to remedy this. I've tried setting the frame to integers to prevent them from being on .5 pixels. - (UITextField *)textControlForSetting:(NSDictionary *)settings { CGRect frame = CGRectIntegral(CGRectMake(100.0f, 0.0f, 170.0f, 44.0f)); UITextField *textField = [[[UITextField alloc] initWithFrame:frame] autorelease]; NSString *defaultValue = [settings objectForKey:kDefaultValueKey]; NSString *currentValue = [prefs objectForKey:[settings objectForKey:kSettingKey]]; textField.tag = settingsCounter; textField.delegate = self; textField.textAlignment = UITextAlignmentRight; textField.font = [UIFont fontWithName:@"HelveticaNeue" size:14.0f]; textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; textField.placeholder = (currentValue != nil) ? currentValue : defaultValue; settingsCounter++; return textField; }

• what is the best way to stream a audio file to website users/listners

  - by Naveen Chamikara Gamage

  I'm developing a music site which will stream audio files stored in a server to users, audio files will be played through flash player placed in a webpage.. As I heard I need to use a streaming media server for streaming audio files ( like 2mb to 3mb in size).. Do I need to use one? I found some streaming media server softwares like http://www.icecast.org - but as in their documentation, It is used for streaming radio stations and live streaming purposes, but I just need to stream audio files faster and in low size (low bandwidth) with good quality.. I heard I need to encode the audio files first and then send them to listeners and in their end audio files need to be decoded again. Is that true? How can I do that? if I need to use a special web server, where should I host my files? Any good hosting providers? if I host audio files in a normal web server, they will use HTTP or TCP to deliver my audio files to users/ listners but I found that HTTP and TCP are not good ways to use for multi media purposes like streaming audio and video files, and they are used for delivering HTML and stuff. I found I should use RSTP or UDP for streaming audio files.. What should I use? I know that .MP3 files has much better quality than the other formats but it also gives huge size to the audio files.. which format should I use for audio files? Most of the best quality audio files are more than 7mb so I'm planning to convert them my self using a software so I could get low size files with some level of good quality. If I'm converting my audio files what is the good BITRATE I should use for my files? Any known best softwares for converting audio files while keeping quality in a good level? Note** - I know that I will not need complex requirements at the beginning of the site but I wanted to what are the best ways like they are using for soundcloud.com

• Why I cannot get correct class of a custom class through isKindOfClass?

  - by Anthony Chan

  Hi, I've created a custom class AnimalView which is a subclass of UIView containing a UILabel and a UIImageView. @interface AnimalView : UIView { UILabel *nameLabel; UIImageView *picture; } Then I added in several AnimalView onto the ViewController.view. In the touchesBegan:withEvent: method, I wanted to detect if the touched object is an AnimalView or not. Here is the code for the viewController: @implementation AppViewController - (void)viewDidLoad { UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:... [self.view addSubview scrollview]; for (int i = 0; i<10; i++) { AnimalView *newAnimal = [[AnimalView alloc] init]; // customization of newAnimal [scrollview addSubview:newAnimal; } } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; UIView *hitView = touch.view; if ([hitView isKindOfClass:[AnimalView class]]) { AnimalView *animal = (AnimalView *)hitView; [animal doSomething]; } } However, nothing happened when I clicked on the animal. When I checked the class of hitView by NSLog(@"%@", [hitView class]), it always shows UIView instead of AnimalView. Is it true that the AnimalView changed to a UIView when it is added onto the ViewController? Is there any way I can get back the original class of a custom class?

• Forcing CLLocationManager updates - does it help or hurt?

  - by Steve N

  I've been trying to find any way to optimize the performance of my location-based iPhone application and have seen some people mention that you can force location updates by starting and stopping your CLLocationManager. I need the best accuracy I can get, and the user in my case would probably like to see updates every few seconds (say, 10 seconds) as they walk around. I've set the filters accordingly, but I notice that sometimes I don't get any updates on the device for quite some time. I'm testing the following approach, which forces an update when a fixed time interval passes (I'm using 20 seconds). My gut tells me this really won't help me provide more accurate updates to the user, and that just leaving CLLocationManager running all the time is probably the best approach. - (void)forceLocationUpdate { [[LocationManager locationManager] stopUpdates]; [[LocationManager locationManager] startUpdates]; [self performSelector:@selector(forceLocationUpdate) withObject:nil afterDelay:20.0]; } My question is- does forcing updates from CLLocationManager actually improve core location performance? Does it hurt performance? If I'm outside in an open field with good GPS reception, will this help then? Does anyone have experience trying this? Thanks in advance, Steve

• Strange behavior due to wx.Frame.SetTitle

  - by Anurag Uniyal

  In a wxPython application, which i am porting to Mac OSX, I set title of app frame every 500msec in update UI event, and due to that all the panels and windows are refreshed. That seems strange to me and almost halts my application which has many custom drawn controls and screens. I wanted to know what could be the reason behind it, is it normal for MAC? Here is a self-constrained script which replicates the scenario using timers. It keeps on printing "on paint" every 500ms because in timer I set title every 500ms. import wx app = wx.PySimpleApp() frame = wx.Frame(None, title="BasePainter Test") painter = wx.Panel(frame) def onPaint(event): dc = wx.PaintDC(painter) print "onPaint" painter.Bind(wx.EVT_PAINT, onPaint) def loop(): frame.SetTitle(frame.GetTitle()) wx.CallLater(500, loop) loop() frame.Show(True) app.SetTopWindow(frame) app.MainLoop() My system details: >>> sys.version '2.5 (r25:51918, Sep 19 2006, 08:49:13) \n[GCC 4.0.1 (Apple Computer, Inc. build 5341)]' >>> wx.VERSION (2, 8, 10, 1, '') >>> os.uname() ('Darwin', 'agyeys-mac-mini.local', '9.8.0', 'Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386', 'i386')

• Is This a Valid Way to Use Blocks in Objective-C?

  - by Carter

  I've been building a HTTP client that uses web services to synchronize information between the client and server. I've been using Blocks and NSURLConnection to achieve this on the client side, but I'm getting frequent EXC_BAD_ACCESS crashes in objc_msgSend(). From what I understand, this usually means that a stored block that has fallen off the stack has been called. I think I've coded things correctly to avoid this, but I'm still stuck. Here is conceptually what my code is doing. It starts by calling "synchronizeWithWebServer". That method invokes "listRootObjectsOnServerWithBlock:" which takes in a block to be called when the method returns. "listRootObjectsOnServersWithBlock:" initiates a NSURLConnection to the web server asynchronously. It to expects a block to be called when it returns. Inside that block I want to be able to execute the original Block (so aptly named 'block'). This is only a simplified version of my code. The real synchronization process is more complex but it's mostly more of the same as what you see below. Sometimes the code works perfectly, but about 80% of the time it crashes very early on in the routine. It seems to be more vulnerable to crashing when my data set gets larger. - (void)synchronizeWithWebServer { [self listRootObjectsOnServerWithBlock:^(NSArray *results, NSError *error) { //Iterate over result objects and perform some other similar routines. }]; } - (void)listRootObjectsOnServerWithBlock:(void (^)(NSArray *results, NSError *error))block { //Create NSURLRequest Here //Create connection asynchronously. block = [block copy]; [NSURLConnection sendAsynchronousRequest:urlRequest queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){ //Parse response from web server (stored in NSData *data) NSArray *results = ..... //Call 'block' block(results, error); [block release]; }]; }

• Group multiple media queries formed as output of LESS css

  - by Goje87

  I was planning to use LESS css in my project (PHP). I am planning to use its nested @media query feature. I find that it fails to group the multiple media queries in the output css it generates. For example: // LESS .header { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 12px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 16px; font-weight: bold; } } .body { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 10px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 12px; } } // output CSS @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } } @media all and (min-width: 240px) and (max-width: 319px) { .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .body { font-size: 12px; } } My expected output is (@media queries grouped) @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } .body { font-size: 12px; } } I would like to know if it can be done in LESS it self or is there any simple CSS parser I can use to manipulate the output CSS to group the @media queries.

• singleton pattern in Windows Activation Service

  - by Joshua

  Hello I have a few WCF services that are currently being self hosted, in a very basic NT Service. I want to expand my application to add provisioning of WCF Services, and updates, as well as isolation (I want each WCF Service to be in its own AppDomain). These WCF Services contain logic that needs to be run on a regular basis, pinging the database, and getting information from external devices so that when a request comes in the data is readily available. I'm thinking about trying out Windows Activation Service, because i really like the provisioning, and isolation that comes with a managed services infrastructure. If I didn't use WAS I would essentially have to write the same code myself. From what I understand though WAS does not really support the model of having a service that is running before someone actually calls a method on the service. the article I read here MSDN Article Link states "That means in essence that out-of-the-box WAS hosting is not something that is really suited for sessionful or singleton services. It is more suitable for stateless per-call services." it does say that "Out of the box" so I'm wondering if anyone has used WAS to host a WCF service that really behaves more like an NT Service (starting and stopping independantly of having a method called upon it). Or any other ideas would be great. I was planning on writting this infrastructure myself, to host WCF services in a custom ServiceHost, and put their execution in a seporate AppDomain, as well as allow for provision of these services after initial installation, along with updates. However, I would MUCH MUCH MUCH rather not own that code if I don't have to. thanks Joshua

• x-dom-event-stream in Opera 10 Only Working on First Event

  - by Brad

  I have a python script (in the CherryPy framework) that sends Event: and data: text as this Opera blog post describes to a client browser. The javascript that recieves the x-dom-event-stream content is almost identical to what they show in the blog post. However, the browser displays only the first event sent. Anyone know what I'm missing? I tried a few older versions of Opera and found that it works in Opera 9.52 but not in any newer versions. What did they change? Here is the python code: class dumpData(object): def index(self): cherrypy.response.headers['Content-Type'] = "application/x-dom-event-stream" def yieldData(): i = 0 while 1: yield "Event: count\n" yield "data: " yield i yield "\n\n" i = i + 1 time.sleep(3); return yieldData() index._cp_config = {'response.stream': True} index.exposed = True And here is the javascript/html. Making a request to /data/ runs the python function above. <head> <script> onload = function() { document.getElementById("count").addEventListener("cout", cout, false); } function count(e) { document.getElementById("stream").firstChild.nodeValue = e.data; } </script> <event-source id="count" src="/data/"> </head> <body> <div id="stream"></div> </body> Opening the direct /data/ url in Firefox saves the stream to a file. So I know the output is in the correct format and that the stream works at all.

• What is the Best way to databind an ASP.NET TreeView for table with many to many parent child relati

  - by Matt W

  I've got a table which has the usual ParentID, ChildID as it's first two columns in a self-referencing tree data structure. My issue is that when I pull this out and use the following code: DataSet set = DA.GetNewCategories(); set.Relations.Add( new DataRelation("parentChildCategories", set.Tables[0].Columns["CategoryParentID"], set.Tables[0].Columns["CategoryID"]) ); StringBuilder buildXml = new StringBuilder(); StringWriter writer = new StringWriter(buildXml); set.WriteXml(writer); TreeView2.DataSource = new HierarchicalDataSet(set, "CategoryID", "CategoryParentID"); TreeView2.DataBind(); I get the error: These columns don't currently have unique values I believe this is because my data has children with multiple parent nodes. This is fine for my application - I don't mind if one row of data is rendered in multiple nodes of my TreeView. Could someone shed light on this please? It doesn't seem unreasonable to have a DataSet render XML which has nodes appearing in multiple places, but I can't figure out how to do it. Thanks, Matt.

• Can Django admin handle a one-to-many relationship via related_name?

  - by Mat

  The Django admin happily supports many-to-one and many-to-many relationships through an HTML <SELECT> form field, allowing selection of one or many options respectively. There's even a nice Javascript filter_horizontal widget to help. I'm trying to do the same from the one-to-many side through related_name. I don't see how it's much different from many-to-many as far as displaying it in the form is concerned, I just need a multi-select SELECT list. But I cannot simply add the related_name value to my ModelAdmin-derived field list. Does Django support one-to-many fields in this way? My Django model something like this (contrived to simplify the example): class Person(models.Model): ... manager = models.ForeignKey('self', related_name='staff', null=True, blank=True, ) From the Person admin page, I can easily get a <SELECT> list showing all possible staff to choose this person's manager from. I also want to display a multiple-selection <SELECT> list of all the manager's staff. I don't want to use inlines, as I don't want to edit the subordinates details; I do want to be able to add/remove people from the list. (I'm trying to use django-ajax-selects to replace the SELECT widget, but that's by-the-by.)

  Hello, startTrains() -> TotalDist = 100, Trains = [trainA,trainB ], PID = spawn(fun() -> train(1,length(Trains)) end), [ PID ! {self(),TrainData,TotalDist} || TrainData <- Trains], receive {_From, Mesg} -> error_logger:info_msg("~n Mesg ~p ~n",[Mesg]) after 10500 -> refresh end. so, I created Two Processes named trainA, trainB. I want to increment these process by 5 till it gets 100. I made different processes to make each of the train (process) increments its position parallely. But I was surprised to get the output sequentially i.e process trainA ends then process trainB starts. But I want to increment themselves at simultaneously. I want to run processes like this trainA 10 trainB 0 trainA 15 trainB 5 .... trainA 100 trainB 100 but I m getting trainA 0 .... trainA 90 trainA 95 trainA 100 trainA ends trainB 0 trainB 5 trainB 10 ..... trainB 100 How to make the processes run parallel/simultaneously? Hope you get my Q's. Please help me.

• Looking for Hardware that will easily interface with my .NET code.

  - by SkippyFire

  I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

  Hello! I have a CCLabelAtlas that I have on a layer to display the current score within my game...the problem that I am having with it is that it does not update when I use [scoreLabel setString:]. Here's how I have it laid out: In the header: @interface GameScene : CCLayer { ... CCLabelAtlas* scoreLabel; } And in the init: scoreLabel = [[CCLabelAtlas alloc] initWithString:@"0" charMapFile:@"scoreCharMap.png" itemWidth:6 itemHeight:8 startCharMap:'.']; [scoreLabel setPosition:ccp(105, 414)]; [self addChild:scoreLabel z: 6]; scoreCharMap.png is a custom map that includes ./0123456789 of my desired font. When the score is changed, I attempt to do this to get the label to update with the current score: NSString* str = [[NSString alloc] initWithFormat:@"%d", [[GameRunner sharedInstance] currentScore]]; [scoreLabel setString: str]; [str release]; [scoreLabel draw]; Problem is that it doesn't ever update - it just sits there and displays 0. I know for a fact due to breakpoints and debugging that setString is being called, and that the string that it should be displaying is correct - but it just doesn't update. Hard-coding the value and saying [scoreLabel setString:@"1234"] does nothing, either. What am I doing wrong here? I am using Cocos2d 0.99 - thanks in advance!

• By using " editingStyleForRowAtIndexPath " method , " didSelectRowAtIndexPath " method is not calle

  - by Madan Mohan

  Hi, the delegate method not called -(void)viewWillAppear:(BOOL)animated { [theTableView setEditing:TRUE animated:TRUE]; } -(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleDelete; } by calling the above the methods i will get minus component before each cell in table view. But the below method didSelectRowAtIndexPath is not called and disclouser indicator is not in visible. (void )tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [theTableView deselectRowAtIndexPath:indexPath animated:YES]; ContactEditViewCotroller *contactEditViewCotroller=[[ContactEditViewCotroller alloc]init]; contactEditViewCotroller.isEdit=isEdit; if(isEdit == YES) { for(int i=0; i<=[editObject.contactList count]-1;i++) { if(indexPath.section == i) { appDelegate.isAddInEdit=NO; editcontacts = [editObject.contactList objectAtIndex:i]; contactEditViewCotroller.editcontacts=editcontacts; indexRow=i; } } } else { for(int i=0; i<=[addContactList count]-1;i++) { if(indexPath.section == i) { appDelegate.isAddInEdit=NO; Contacts *obj = [addContactList objectAtIndex:i]; contactEditViewCotroller.addcontacts=obj; } } } [[self navigationController] pushViewController:contactEditViewCotroller animated:YES]; [contactEditViewCotroller release]; }

• Quadratic Bezier Curve: Calculate Tangent

  - by stefan.at.wpf

  I have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivative of the formula for the quadratic bezier curve; however I get 400 as value for the slope, though it should be 0. Maybe I'm using the first derivative in a wrong way? I know I could also calculate the tangents using trigonometric functions; however I'd like to do it using the first derivative, shouldn't this be possible? Thanks for any hint! For clarification / please note: I'm interested in a general way to get the slope in a arbitrary given point on a quadratic bezier curve, not only to get the tangent in the start- and end point. A picture of my problem including the text above: http://cid-0432ee4cfe9c26a0.skydrive.live.com/self.aspx/%c3%96ffentlich/Quadratic%20Bezier%20Curve.pdf Thank you very much for any hint!

  - by mcgrailm

  Hello all working on my building my first iDevice app and I am trying to populate a UITableView with data from json result I can get it to load from plist array no propblem and I can even see my json the problem I'm having is that the UITableView never gets to see the json results please bare with me as this is first time with obj-c or anything like it in my .h file @interface TableViewViewController : UIViewController <UITableViewDataSource, UITableViewDelegate> { NSArray *exercises; NSMutableData *responseData; } in my .m file - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return exercises.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //create a cell UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; // fill it with contnets cell.textLabel.text = [exercises objectAtIndex:indexPath.row]; // return it return cell; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { responseData = [[NSMutableData data] retain]; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://url_to_json"]]; [[NSURLConnection alloc] initWithRequest:request delegate:self ]; // load from plist //NSString *myfile = [[NSBundle mainBundle] pathForResource:@"exercise" ofType:@"plist"]; //exercises = [[NSArray alloc] initWithContentsOfFile:myfile]; [super viewDidLoad]; } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [responseData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"Connection failed: %@", [error description]); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; [responseData release]; NSDictionary *dictionary = [responseString JSONValue]; NSArray *response = [dictionary objectForKey:@"response"]; exercises = [[NSArray alloc] initWithArray:response]; }

• Testing warnings with doctest

  - by Eli Courtwright

  I'd like to use doctests to test the presence of certain warnings. For example, suppose I have the following module: from warnings import warn class Foo(object): """ Instantiating Foo always gives a warning: >>> foo = Foo() testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) >>> """ def __init__(self): warn("Boo!", UserWarning) If I run python -m doctest testdocs.py to run the doctest in my class and make sure that the warning is printed, I get: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) ********************************************************************** File "testdocs.py", line 7, in testdocs.Foo Failed example: foo = Foo() Expected: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) Got nothing ********************************************************************** 1 items had failures: 1 of 1 in testdocs.Foo ***Test Failed*** 1 failures. It looks like the warning is getting printed but not captured or noticed by doctest. I'm guessing that this is because warnings are printed to sys.stderr instead of sys.stdout. But this happens even when I say sys.stderr = sys.stdout at the end of my module. So is there any way to use doctests to test for warnings? I can find no mention of this one way or the other in the documentation or in my Google searching.
