• unittest import error with virtualenv + google-app-engine-django

  - by Ray Yun

  I'm working with google-app-engine-django + zipped django. Just running "python manage.py test" succeeded without error. But with virtualenv, test was failed with "import unittest error". same error with Django 1.1. - OSX 10.5.6 - google-app-engine-django (r101 via svn) : r100 was failed with launcher 1.3.0 - GoogleAppLauncher 1.3.0 -

• Encoded nsstring becomes invalid, "normal" nsstring remains

  - by shoreline

  I'm running into a problem with a string that contains encoded characters. Specifically, if the string has encoded characters it eventually becomes invalid while a "normal" string will not. in the .h file: @interface DirViewController : TTThumbsViewController <UIActionSheetDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate> { NSString *sourceFolder; NSString *encodedSourceFolder; } @property (nonatomic, retain) NSString *sourceFolder; @property (nonatomic, retain) NSString *encodedSourceFolder; in the .m file: - (id)initWithFolder:(NSString*)folder query:(NSDictionary*)query { if (self = [super init]) { sourceFolder = folder; } return self; } Up to now everything seems to run as expected. In viewDidLoad I have the following: sourceFolderCopy = [self urlEncodeValue:(sourceFolder)]; //I also have this button, which I'll refer to later: UIBarButtonItem *importButton = [[UIBarButtonItem alloc] initWithTitle:@"Import/Export" style:UIBarButtonItemStyleBordered target:self action:@selector(importFiles:)]; self.navigationItem.rightBarButtonItem = importButton; Which uses the following method to encode the string (if it has characters I want encoded): - (NSString *)urlEncodeValue:(NSString *)str { NSString *result = (NSString *) CFURLCreateStringByAddingPercentEscapes (kCFAllocatorDefault, (CFStringRef)str, NULL, CFSTR(":/?#[]@!$&’()*+,;="), kCFStringEncodingUTF8); return [result autorelease]; } If I NSLog result, I get the expected values. If the string has characters like a white space, I get a string with encoding. If the string doesn't have any characters that need to be encoded, it just gives me the original string. I have a button on the nav bar which begins an image import process by opening an action sheet. Once the method for the action sheet starts, my string is invalid - but only if it contains encoded characters. If it is just a "normal" string, everything is fine and acts as expected. Am I off on my encoding? At first I thought it might be a memory problem but I can't figure out why that would affect only encoded strings. Here's where the action sheet is defined (and the first place I can see the encoded string becoming invalid) the NSLog statements are where it crashes: - (IBAction)importFiles:(id)sender { NSLog(@"logging encodedSF from import files:"); NSLog(@"%@",encodedSourceFolder);//crashes right here NSLog(@"%@",sourceFolder); if (shouldNavigate == NO) { NSString *msg = nil; msg = @"It is not possible to import or export images while in image selection mode."; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unable to Import/Export" message:msg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; [msg release]; } else{ UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"What would you like to do?" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Import Photos (Picker)", @"Export Photos", nil, nil]; [actionSheet showInView:self.view]; [actionSheet release]; } } I don't get any crash errors going to the console. By using breakpoints I was able to see that the encodedSourceFolder is invalid in the action sheet method.

• How to get objects to react to touches in Cocos2D?

  - by Wayfarer

  Alright, so I'm starting to learn more about Coco2D, but I'm kinda frusterated. A lot of the tutorials I have found are for outdated versions of the code, so when I look through and see how they do certain things, I can't translate it into my own program, because a lot has changed. With that being said, I am working in the latest version of Coco2d, version 0.99. What I want to do is create a sprite on the screen (Done) and then when I touch that sprite, I can have "something" happen. For now, let's just make an alert go off. Now, I got this code working with the help of a friend. Here is the header file: // When you import this file, you import all the cocos2d classes #import "cocos2d.h" // HelloWorld Layer @interface HelloWorld : CCLayer { CGRect spRect; } // returns a Scene that contains the HelloWorld as the only child +(id) scene; @end And here is the implementation file: // // cocos2d Hello World example // http://www.cocos2d-iphone.org // // Import the interfaces #import "HelloWorldScene.h" #import "CustomCCNode.h" // HelloWorld implementation @implementation HelloWorld +(id) scene { // 'scene' is an autorelease object. CCScene *scene = [CCScene node]; // 'layer' is an autorelease object. HelloWorld *layer = [HelloWorld node]; // add layer as a child to scene [scene addChild: layer]; // return the scene return scene; } // on "init" you need to initialize your instance -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super" return value if( (self=[super init] )) { // create and initialize a Label CCLabel* label = [CCLabel labelWithString:@"Hello World" fontName:@"Times New Roman" fontSize:64]; // ask director the the window size CGSize size = [[CCDirector sharedDirector] winSize]; // position the label on the center of the screen label.position = ccp( size.width /2 , size.height/2 ); // add the label as a child to this Layer [self addChild: label]; CCSprite *sp = [CCSprite spriteWithFile:@"test2.png"]; sp.position = ccp(300,200); [self addChild:sp]; float w = [sp contentSize].width; float h = [sp contentSize].height; CGPoint aPoint = CGPointMake([sp position].x - (w/2), [sp position].y - (h/2)); spRect = CGRectMake(aPoint.x, aPoint.y, w, h); CCSprite *sprite2 = [CCSprite spriteWithFile:@"test3.png"]; sprite2.position = ccp(100,100); [self addChild:sprite2]; //[self registerWithTouchDispatcher]; self.isTouchEnabled = YES; } return self; } // on "dealloc" you need to release all your retained objects - (void) dealloc { // in case you have something to dealloc, do it in this method // in this particular example nothing needs to be released. // cocos2d will automatically release all the children (Label) // don't forget to call "super dealloc" [super dealloc]; } - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //CGPoint location = [[CCDirector sharedDirector] convertCoordinate:[touch locationInView:touch.view]]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(spRect, location)) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Win" message:@"testing" delegate:nil cancelButtonTitle:@"okay" otherButtonTitles:nil]; [alert show]; [alert release]; NSLog(@"TOUCHES"); } NSLog(@"Touch got"); } However, this only works for 1 object, the sprite which I create the CGRect for. I can't do it for 2 sprites, which I was testing. So my question is this: How can I have all sprites on the screen react to the same event when touched? For my program, the same event needs to be run for all objects of the same type, so that should make it a tad easier. I tried making a subclass of CCNode and over write the method, but that just didn't work at all... so I'm doing something wrong. Help would be appreciated!

• Convert NSData to primitive variable with ieee-754 or twos-complement ?

  - by William GILLARD

  Hi every one. I am new programmer in Obj-C and cocoa. Im a trying to write a framework which will be used to read a binary files (Flexible Image Transport System or FITS binary files, usually used by astronomers). The binary data, that I am interested to extract, can have various formats and I get its properties by reading the header of the FITS file. Up to now, I manage to create a class to store the content of the FITS file and to isolate the header into a NSString object and the binary data into a NSData object. I also manage to write method which allow me to extract the key values from the header that are very valuable to interpret the binary data. I am now trying to convert the NSData object into a primitive array (array of double, int, short ...). But, here, I get stuck and would appreciate any help. According to the documentation I have about the FITS file, I have 5 possibilities to interpret the binary data depending on the value of the BITPIX key: BITPIX value | Data represented 8 | Char or unsigned binary int 16 | 16-bit two's complement binary integer 32 | 32-bit two's complement binary integer 64 | 64-bit two's complement binary integer -32 | IEEE single precision floating-point -64 | IEEE double precision floating-point I already write the peace of code, shown bellow, to try to convert the NSData into a primitive array. // self reefer to my FITS class which contain a NSString object // with the content of the header and a NSData object with the binary data. -(void*) GetArray { switch (BITPIX) { case 8: return [self GetArrayOfUInt]; break; case 16: return [self GetArrayOfInt]; break; case 32: return [self GetArrayOfLongInt]; break; case 64: return [self GetArrayOfLongLong]; break; case -32: return [self GetArrayOfFloat]; break; case -64: return [self GetArrayOfDouble]; break; default: return NULL; } } // then I show you the method to convert the NSData into a primitive array. // I restrict my example to the case of 'double'. Code is similar for other methods // just change double by 'unsigned int' (BITPIX 8), 'short' (BITPIX 16) // 'int' (BITPIX 32) 'long lon' (BITPIX 64), 'float' (BITPIX -32). -(double*) GetArrayOfDouble { int Nelements=[self NPIXEL]; // Metod to extract, from the header // the number of element into the array NSLog(@"TOTAL NUMBER OF ELEMENTS [%i]\n",Nelements); //CREATE THE ARRAY double (*array)[Nelements]; // Get the total number of bits in the binary data int Nbit = abs(BITPIX)*GCOUNT*(PCOUNT + Nelements); // GCOUNT and PCOUNT are defined // into the header NSLog(@"TOTAL NUMBER OF BIT [%i]\n",Nbit); int i=0; //FILL THE ARRAY double Value; for(int bit=0; bit < Nbit; bit+=sizeof(double)) { [Img getBytes:&Value range:NSMakeRange(bit,sizeof(double))]; NSLog(@"[%i]:(%u)%.8G\n",i,bit,Value); (*array)[i]=Value; i++; } return (*array); } However, the value I print in the loop are very different from the expected values (compared using official FITS software). Therefore, I think that the Obj-C double does not use the IEEE-754 convention as well as the Obj-C int are not twos-complement. I am really not familiar with this two convention (IEEE and twos-complement) and would like to know how I can do this conversion with Obj-C. In advance many thanks for any help or information.

• Saving UIImagePickerController images to Core Data without crashing

  - by Gordon Fontenot

  I have been trying to minimize my memory footprint with UIImagePickerController, but I'm starting to think that the memory problems I am having are resulting from poor memory management, instead of a particular way to handle the UIImagePickerController object. My workflow is this: The "Edit Image" button is clicked, which presents a UIActionSheet. This action sheet allows you to delete, take a picture, choose from the library, or cancel. If you select Choose from the library or Take Picture, I alloc an instance of UIImagePickerController and present it, followed by a release of UIImagePickerController: -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (actionSheet.tag != 999) { UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; BOOL pickImage = nil; if (actionSheet.tag == iPhoneWithDelete) { switch (buttonIndex) { case 0: object.objectImage = nil; pickImage = NO; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; pickImage = YES; break; case 2: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPhoneNoDelete) { switch (buttonIndex) { case 0: imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; pickImage = YES; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPodWithDelete) { switch (buttonIndex) { case 0: object.objectImage = nil; pickImage = NO; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPodNoDelete) { switch (buttonIndex) { case 0: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } if (pickImage) { imagePicker.allowsEditing = YES; [self presentModalViewController:imagePicker animated:YES]; } else { [self setupImageButton]; [self setupChooseImageButton]; } [imagePicker release]; } } Once I get a selection back from the UIImagePickerController, I save 2 images, a resized version of the edited image to use for a thumbnail, and a 800x600 version of the original unedited image into a relationship attribute (Transformational, using the same UIImage to PNG transformations found in the Recipes demo code) for display use: (the resize methods are based on the one demoed in this SO post.) - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [self dismissModalViewControllerAnimated:YES]; NSManagedObject *oldImage = object.imageFull; if (oldImage != nil) { [object.managedObjectContext deleteObject:oldImage]; } NSManagedObject *image = [NSEntityDescription insertNewObjectForEntityForName:@"Image" inManagedObjectContext:object.managedObjectContext]; object.imageFull = image; UIImage *rawImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; CGSize size = CGSizeMake(800, 600); UIImage *fullImage = [UIImageManipulator scaleImage:rawImage toSize:size]; [image setValue:fullImage forKey:@"imageFull"]; UIImage *processedImage = [UIImageManipulator scaleImage:[info objectForKey:@"UIImagePickerControllerEditedImage"] toSize:CGSizeMake(75, 75)]; object.objectImage = processedImage; [self setupImageButton]; [self setupChooseImageButton]; rawImage = nil; fullImage = nil; processedImage = nil; } When I go through viewDidUnload I am setting self.object = nil, and [object release] during dealloc, but I'm still getting memory warnings after about 10 image changes, with a crash at around 20. It leads me to believe that I am not getting that full image out of memory the correct way. What am I missing here? And on a second note, does the Camera source use significantly more memory than the Photo Albums source? I tend to get more crashes when using the camera.

• NSFetchedResultsController: using of NSManagedObjectContext during update brings to crash

  - by Kentzo

  Here is the interface of my controller class: @interface ProjectListViewController : UITableViewController <NSFetchedResultsControllerDelegate> { NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } @end I use following code to init fetchedResultsController: if (fetchedResultsController != nil) { return fetchedResultsController; } // Create and configure a fetch request with the Project entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Project" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // Create the sort descriptors array. NSSortDescriptor *projectIdDescriptor = [[NSSortDescriptor alloc] initWithKey:@"projectId" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:projectIdDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Create and initialize the fetch results controller. NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:nil]; self.fetchedResultsController = aFetchedResultsController; fetchedResultsController.delegate = self; As you can see, I am using the same managedObjectContext as defined in my controller class Here is an adoption of the NSFetchedResultsControllerDelegate protocol: - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self _configureCell:(TDBadgedCell *)[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: if (newIndexPath != nil) { [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; } else { [tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationFade]; } break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { [self.tableView endUpdates]; } Inside of the _configureCell:atIndexPath: method I have following code: NSFetchRequest *issuesNumberRequest = [NSFetchRequest new]; NSEntityDescription *issueEntity = [NSEntityDescription entityForName:@"Issue" inManagedObjectContext:managedObjectContext]; [issuesNumberRequest setEntity:issueEntity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"projectId == %@", project.projectId]; [issuesNumberRequest setPredicate:predicate]; NSUInteger issuesNumber = [managedObjectContext countForFetchRequest:issuesNumberRequest error:nil]; [issuesNumberRequest release]; I am using the managedObjectContext again. But when I am trying to insert new Project, app crashes with following exception: Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-984.38/UITableView.m:774 Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (4) must be equal to the number of rows contained in that section before the update (4), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).' Fortunately, I've found a workaround: if I create and use separate NSManagedObjectContext inside of the _configureCell:atIndexPath: method app won't crash! I only want to know, is this behavior correct or not?

• NSUserDefaults loses 3 rows each time it's called

  - by Jeff Decker

  Hello Everyone! Brand new programmer here, so off-topic help/constructive criticism welcome. I am saving a default state (such as "New York") in a UIPickerView which is in a FlipSideView. It certainly saves for the first and second time I check to make sure it's the same state (I am clicking "done" and then "info" repeatedly), but on the third check the picker has moved up three states (to "New Hampshire") and then every time I check the picker progresses three more states. Here's the .h and .m files of the FlipSideViewController: #import <UIKit/UIKit.h> import "Calculator.h" @protocol FlipsideViewControllerDelegate; @interface FlipsideViewController : UIViewController { id delegate; UIPickerView *myPickerView; NSArray *pickerViewArray; } @property (nonatomic, assign) id delegate; @property (nonatomic, retain) UIPickerView *myPickerView; @property (nonatomic, retain) NSArray *pickerViewArray; (IBAction)done; @end @protocol FlipsideViewControllerDelegate - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller; @end import "FlipsideViewController.h" @implementation FlipsideViewController @synthesize delegate; @synthesize myPickerView, pickerViewArray; -(CGRect)pickerFrameWithSize:(CGSize)size;{ CGRect screenRect = [[UIScreen mainScreen] applicationFrame]; CGRect pickerRect = CGRectMake( 0.0, screenRect.size.height - size.height, size.width, size.height); return pickerRect; } (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor]; [self createPicker]; } -(void)viewWillAppear:(BOOL)animated;{ [super viewWillAppear:NO]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [myPickerView selectRow:[defaults integerForKey:@"pickerRow"] inComponent:0 animated:NO]; } -(void)createPicker;{ pickerViewArray = [[NSArray arrayWithObjects: @"Alabama",@"Alaska", @"Arizona",@"Arkansas",@"California",@"Colorado",@"Connecticut",@"Delaware", @"District of Columbia",@"Florida",@"Georgia",@"Hawaii",@"Idaho",@"Illinois",@"Indiana",@"Iowa", @"Kansas",@"Kentucky",@"Louisiana",@"Maine",@"Maryland",@"Massachusetts",@"Michigan", @"Minnesota",@"Mississippi",@"Missouri",@"Montana",@"Nebraska",@"Nevada",@"New Hampshire",@"New Jersey", @"New Mexico",@"New York",@"North Carolina",@"North Dakota",@"Ohio",@"Oklahoma", @"Oregon",@"Pennsylvania",@"Rhode Island",@"South Carolina",@"South Dakota",@"Tennessee", @"Texas",@"Utah",@"Vermont",@"Virginia",@"Washington",@"West Virginia",@"Wisconsin",@"Wyoming", nil] retain]; myPickerView = [[UIPickerView alloc] initWithFrame:CGRectZero]; CGSize pickerSize = [myPickerView sizeThatFits:CGSizeZero]; myPickerView.frame = [self pickerFrameWithSize:pickerSize]; myPickerView.autoresizingMask = UIViewAutoresizingFlexibleWidth; myPickerView.showsSelectionIndicator = YES; myPickerView.delegate = self; myPickerView.dataSource = self; [self.view addSubview:myPickerView]; } (IBAction)done { [self.delegate flipsideViewControllerDidFinish:self]; } pragma mark - pragma mark UIPickerViewDataSource (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setInteger:row forKey:@"pickerRow"]; [defaults setObject:[pickerViewArray objectAtIndex:row] forKey:@"pickerString"]; return [pickerViewArray objectAtIndex:row]; } (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setInteger:row forKey:@"pickerRow"]; [defaults setObject:[pickerViewArray objectAtIndex:row] forKey:@"pickerString"]; } (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component { return 240.0; } (CGFloat)pickerView:(UIPickerView *)pickerView rowHeightForComponent:(NSInteger)component { return 40.0; } (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [pickerViewArray count]; } (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } call me mystified! Thanks for any help. Please let me know if I can make myself more clear...

• Why isn't my algorithm for find the biggest and smallest inputs working?

  - by Matt Ellen

  I have started a new job, and with it comes a new language: Ironpython. Thankfully a good language :D Before starting I got to grips with Python on the whole, but that was only a week's worth of learning. Now I'm writing actual code. I've been charged with writing an algorithm that finds the best input parameter to collect data with. The basic algorithm is (as I've been instructed): Set the input parameter to a good guess Start collecting data When data is available stop collecting find the highest point If the point before this (i.e. for the previous parameter value) was higher and the point before that was lower then we've found the max otherwise the input parameter is increased by the initial guess. goto 2 If the max is found then the min needs to be found. To do this the algorithm carries on increasing the input, but by 1/10 of the max, until the current point is greater than the previous point and the point before that is also greater. Once the min is found then the algorithm stops. Currently I have a simplified data generator outputting the sin of the input, so that I know that the min value should be PI and the max value should be PI/2 The main Python code looks like this (don't worry, this is just for my edification, I don't write real code like this): import sys sys.path.append(r"F:\Programming Source\C#\PythonHelp\PythonHelp\bin\Debug") import clr clr.AddReferenceToFile("PythonHelpClasses.dll") import PythonHelpClasses from PHCStruct import Helper from System import Math helper = Helper() def run(): b = PythonHelpClasses.Executor() a = PythonHelpClasses.HasAnEvent() b.Input = 0.0 helper.__init__() def AnEventHandler(e): b.Stop() h = helper h.lastLastVal, h.lastVal, h.currentVal = h.lastVal, h.currentVal, e.Number if h.lastLastVal < h.lastVal and h.currentVal < h.lastVal and h.NotPast90: h.NotPast90 = False h.bestInput = h.lastInput inputInc = 0.0 if h.NotPast90: inputInc = Math.PI/10.0 else: inputInc = h.bestInput/10.0 if h.lastLastVal > h.lastVal and h.currentVal > h.lastVal and h.NotPast180: h.NotPast180 = False if h.NotPast180: h.lastInput, b.Input = b.Input, b.Input + inputInc b.Start(a) else: print "Best input:", h.bestInput print "Last input:", h.lastInput b.Stop() a.AnEvent += AnEventHandler b.Start(a) PHCStruct.py: class Helper(): def __init__(self): self.currentVal = 0 self.lastVal = 0 self.lastLastVal = 0 self.NotPast90 = True self.NotPast180 = True self.bestInput = 0 self.lastInput = 0 PythonHelpClasses has two small classes I wrote in C# before I realised how to do it in Ironpython. Executor runs a delegate asynchronously while it's running member is true. The important code: public void Start(HasAnEvent hae) { running = true; RunDelegate r = new RunDelegate(hae.UpdateNumber); AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar = r.BeginInvoke(Input, ac, null); } public void Stop() { running = false; } public void UpdateDone(IAsyncResult ar) { RunDelegate r = (RunDelegate)((AsyncResult)ar).AsyncDelegate; r.EndInvoke(ar); if (running) { AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar2 = r.BeginInvoke(Input, ac, null); } } HasAnEvent has a function that generates the sin of its input and fires an event with that result as its argument. i.e.: public void UpdateNumber(double val) { AnEventArgs e = new AnEventArgs(Math.Sin(val)); System.Threading.Thread.Sleep(1000); if (null != AnEvent) { AnEvent(e); } } The sleep is in there just to slow things down a bit. The problem I am getting is that the algorithm is not coming up with the best input being PI/2 and the final input being PI, but I can't see why. Also the best and final inputs are different each time I run the programme. Can anyone see why? Also when the algorithm terminates the best and final inputs are printed to the screen multiple times, not just once. Can someone explain why?

• segmented controls mangled during initial transition animation

  - by dLux

  greetings and salutations folks, i'm relatively new to objective c & iphone programming, so bare with me if i've overlooked something obvious.. i created a simple app to play with the different transition animations, setting up a couple segmented controls and a slider.. (Flip/Curl), (left/right) | (up/down), (EaseInOut/EaseIn/EaseOut/Linear) i created a view controller class, and the super view controller switches between 2 instances of the sub class. as you can see from the following image, the first time switching to the 2nd instance, while the animation is occurring the segmented controls are mangled; i'd guess they haven't had enuff time to draw themselves completely.. http://img689.imageshack.us/img689/2320/mangledbuttonsduringtra.png they're fine once the animation is done, and any subsequent times.. if i specify cache:NO in the setAnimationTransition it helps, but there still seems to be some sort of progressive reveal for the text in the segmented controls; they still don't seem to be pre-rendered or initialized properly.. (and surely there's a way to do this while caching the view being transitioned to, since in this case the view isn't changing and should be cacheable.) i'm building my code based on a couple tutorials from a book, so i updated the didReceiveMemoryWarning to set the instanced view controllers to nil; when i invoke a memory warning in the simulator, i assume it's purging the other view, and it acts like a first transition after loading, the view being transitioned to appears just like the image above.. i guess it can't hurt to include the code (sorry if it's considered spamming), this is basically half of it, with a similar chunk following this in an else statement, for the case of the 2nd side being present, switching back to the 1st..: - (IBAction)switchViews:(id)sender { [UIView beginAnimations:@"Transition Animation" context:nil]; if (self.sideBViewController.view.superview == nil) // sideA is active, sideB is coming { if (self.sideBViewController == nil) { SideAViewController *sBController = [[SideAViewController alloc] initWithNibName:@"SideAViewController" bundle:nil]; self.sideBViewController = sBController; [sBController release]; } [UIView setAnimationDuration:sideAViewController.transitionDurationSlider.value]; if ([sideAViewController.transitionAnimation selectedSegmentIndex] == 0) { // flip: 0 == left, 1 == right if ([sideAViewController.flipDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; } else { // curl: 0 == up, 1 == down if ([sideAViewController.curlDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; } if ([sideAViewController.animationCurve selectedSegmentIndex] == 0) [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 1) [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 2) [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 3) [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [sideBViewController viewWillAppear:YES]; [sideAViewController viewWillDisappear:YES]; [sideAViewController.view removeFromSuperview]; [self.view insertSubview:sideBViewController.view atIndex:0]; [sideBViewController viewDidAppear:YES]; [sideAViewController viewDidDisappear:YES]; } any other tips or pointers about writing good clean code is also appreciated, i realize i still have a lot to learn.. thank u for ur time, -- d

• How do I code this relationship in SQLAlchemy?

  - by Martin Del Vecchio

  I am new to SQLAlchemy (and SQL, for that matter). I can't figure out how to code the idea I have in my head. I am creating a database of performance-test results. A test run consists of a test type and a number (this is class TestRun below) A test suite consists the version string of the software being tested, and one or more TestRun objects (this is class TestSuite below). A test version consists of all test suites with the given version name. Here is my code, as simple as I can make it: from sqlalchemy import * from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import relationship, backref, sessionmaker Base = declarative_base() class TestVersion (Base): __tablename__ = 'versions' id = Column (Integer, primary_key=True) version_name = Column (String) def __init__ (self, version_name): self.version_name = version_name class TestRun (Base): __tablename__ = 'runs' id = Column (Integer, primary_key=True) suite_directory = Column (String, ForeignKey ('suites.directory')) suite = relationship ('TestSuite', backref=backref ('runs', order_by=id)) test_type = Column (String) rate = Column (Integer) def __init__ (self, test_type, rate): self.test_type = test_type self.rate = rate class TestSuite (Base): __tablename__ = 'suites' directory = Column (String, primary_key=True) version_id = Column (Integer, ForeignKey ('versions.id')) version_ref = relationship ('TestVersion', backref=backref ('suites', order_by=directory)) version_name = Column (String) def __init__ (self, directory, version_name): self.directory = directory self.version_name = version_name # Create a v1.0 suite suite1 = TestSuite ('dir1', 'v1.0') suite1.runs.append (TestRun ('test1', 100)) suite1.runs.append (TestRun ('test2', 200)) # Create a another v1.0 suite suite2 = TestSuite ('dir2', 'v1.0') suite2.runs.append (TestRun ('test1', 101)) suite2.runs.append (TestRun ('test2', 201)) # Create another suite suite3 = TestSuite ('dir3', 'v2.0') suite3.runs.append (TestRun ('test1', 102)) suite3.runs.append (TestRun ('test2', 202)) # Create the in-memory database engine = create_engine ('sqlite://') Session = sessionmaker (bind=engine) session = Session() Base.metadata.create_all (engine) # Add the suites in version1 = TestVersion (suite1.version_name) version1.suites.append (suite1) session.add (suite1) version2 = TestVersion (suite2.version_name) version2.suites.append (suite2) session.add (suite2) version3 = TestVersion (suite3.version_name) version3.suites.append (suite3) session.add (suite3) session.commit() # Query the suites for suite in session.query (TestSuite).order_by (TestSuite.directory): print "\nSuite directory %s, version %s has %d test runs:" % (suite.directory, suite.version_name, len (suite.runs)) for run in suite.runs: print " Test '%s', result %d" % (run.test_type, run.rate) # Query the versions for version in session.query (TestVersion).order_by (TestVersion.version_name): print "\nVersion %s has %d test suites:" % (version.version_name, len (version.suites)) for suite in version.suites: print " Suite directory %s, version %s has %d test runs:" % (suite.directory, suite.version_name, len (suite.runs)) for run in suite.runs: print " Test '%s', result %d" % (run.test_type, run.rate) The output of this program: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 Version v1.0 has 1 test suites: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Version v1.0 has 1 test suites: Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Version v2.0 has 1 test suites: Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 This is not correct, since there are two TestVersion objects with the name 'v1.0'. I hacked my way around this by adding a private list of TestVersion objects, and a function to find a matching one: versions = [] def find_or_create_version (version_name): # Find existing for version in versions: if version.version_name == version_name: return (version) # Create new version = TestVersion (version_name) versions.append (version) return (version) Then I modified my code that adds the records to use it: # Add the suites in version1 = find_or_create_version (suite1.version_name) version1.suites.append (suite1) session.add (suite1) version2 = find_or_create_version (suite2.version_name) version2.suites.append (suite2) session.add (suite2) version3 = find_or_create_version (suite3.version_name) version3.suites.append (suite3) session.add (suite3) Now the output is what I want: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 Version v1.0 has 2 test suites: Suite directory dir1, version v1.0 has 2 test runs: Test 'test1', result 100 Test 'test2', result 200 Suite directory dir2, version v1.0 has 2 test runs: Test 'test1', result 101 Test 'test2', result 201 Version v2.0 has 1 test suites: Suite directory dir3, version v2.0 has 2 test runs: Test 'test1', result 102 Test 'test2', result 202 This feels wrong to me; it doesn't feel right that I am manually keeping track of the unique version names, and manually adding the suites to the appropriate TestVersion objects. Is this code even close to being correct? And what happens when I'm not building the entire database from scratch, as in this example. If the database already exists, do I have to query the database's TestVersion table to discover the unique version names? Thanks in advance. I know this is a lot of code to wade through, and I appreciate the help.

• iPhone App Crashes when merging managed object contexts

  - by DVG

  Short Version: Using two managed object contexts, and while the context is saving to the store the application bombs when I attempt to merge the two contexts and reload the table view. Long Version: Okay, so my application is set up as thus. 3 view controllers, all table views. Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller I ran into a problem when Games View Controller was bombing when adding a new entry to the context, because the fetched results contorller wanted to update the view for something that didn't match the predicate. As a solution, I rebuilt the Add Controller to use a second NSManagedObject Context, called adding context, following the design pattern in the Core Data Books example. My Games List View Controller is a delegate for the add controller, to handle all the saving, so my addButtonPressed method looks like this - (IBAction) addButtonPressed: (id) sender { AddGameTableViewController *addGameVC = [[AddGameTableViewController alloc] initWithNibName:@"AddGameTableViewController" bundle:nil]; NSManagedObjectContext *aAddingContext = [[NSManagedObjectContext alloc] init]; self.addingContext = aAddingContext; [aAddingContext release]; [addingContext setPersistentStoreCoordinator:[[gameResultsController managedObjectContext] persistentStoreCoordinator]]; addGameVC.context = addingContext; addGameVC.delegate = self; addGameVC.newGame = (Game *)[NSEntityDescription insertNewObjectForEntityForName:@"Game" inManagedObjectContext:addingContext]; UINavigationController *addNavCon = [[UINavigationController alloc] initWithRootViewController:addGameVC]; [self presentModalViewController:addNavCon animated:YES]; [addGameVC release]; [addNavCon release]; } There is also a delegate method which handles the saving. This all works swimmingly. The issue is getting the table view controller in the GameListViewController to update itself. Per the example, an observer is added to watch for the second context to be saved, and then to merge the addingContext with the primary one. So I have: - (void)addViewController:(AddGameTableViewController *)controller didFinishWithSave:(BOOL)save { if (save) { NSNotificationCenter *dnc = [NSNotificationCenter defaultCenter]; [dnc addObserver:self selector:@selector(addControllerContextDidSave:) name:NSManagedObjectContextDidSaveNotification object:addingContext]; //snip! Context Save Code [dnc removeObserver:self name:NSManagedObjectContextDidSaveNotification object:addingContext]; } self.addingContext = nil; [self dismissModalViewControllerAnimated:YES]; } - (void)addControllerContextDidSave:(NSNotification*)saveNotification { NSManagedObjectContext *myContext = [gameResultsController managedObjectContext]; [myContext mergeChangesFromContextDidSaveNotification:saveNotification]; } So now, what happens is after save is pressed, the application hangs for a moment and then crashes. The save is processed, as the new game is present when I relaunch the application, and the application seems to be flowing as appropriate, but it bombs out for reasons that are beyond my understanding. NSLog of the saveNotification spits out this: NSConcreteNotification 0x3b557f0 {name = NSManagingContextDidSaveChangesNotification; object = <NSManagedObjectContext: 0x3b4bb90>; userInfo = { inserted = {( <Game: 0x3b4f510> (entity: Game; id: 0x3b614e0 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p2> ; data: { name = "Final Fantasy XIII"; platform = 0x3b66910 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Platform/p20>; }) )}; updated = {( <Platform: 0x3b67650> (entity: Platform; id: 0x3b66910 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Platform/p20> ; data: { games = ( 0x3b614e0 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p2>, 0x603a530 <x-coredata://13168366-B8E7-41C8-B384-BAF14A5E08D9/Game/p1> ); name = "Xbox 360"; }) )}; }} I've tried both a simple [self.tableView reloadData]; and the more complicated multi-method table updating structure in the Core Data Books example. Both produce the same result.

• How to filter using a dropdown in Knockout

  I have just started using Knockout and I want to filter my data that I am displaying in my UI by selecting an item from a dropdown.

• Setting custom UITableViewCells height

  - by Vijayeta

  I am using a custum UITableViewCell which has some labels, buttons and imageviews to be displayed. There is one label in the cell whose text is a NSString object and the length of string could be variable. Due to this, I cannot set a constant height to the cell in the UITableViews: heightForCellAtIndex method. The cell's height depends on the labels height which can be determined using the NSStrings sizeWithFont method. I tried using it, but it looks like I'm going wrong somewhere. How can it be fixed? Here is the code used for initializing the cell. if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) { self.selectionStyle = UITableViewCellSelectionStyleNone; UIImage *image = [UIImage imageNamed:@"dot.png"]; imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(45.0,10.0,10,10); headingTxt = [[UILabel alloc] initWithFrame: CGRectMake(60.0,0.0,150.0,post_hdg_ht)]; [headingTxt setContentMode: UIViewContentModeCenter]; headingTxt.text = postData.user_f_name; headingTxt.font = [UIFont boldSystemFontOfSize:13]; headingTxt.textAlignment = UITextAlignmentLeft; headingTxt.textColor = [UIColor blackColor]; dateTxt = [[UILabel alloc] initWithFrame:CGRectMake(55.0,23.0,150.0,post_date_ht)]; dateTxt.text = postData.created_dtm; dateTxt.font = [UIFont italicSystemFontOfSize:11]; dateTxt.textAlignment = UITextAlignmentLeft; dateTxt.textColor = [UIColor grayColor]; NSString * text1 = postData.post_body; NSLog(@"text length = %d",[text1 length]); CGRect bounds = [UIScreen mainScreen].bounds; CGFloat tableViewWidth; CGFloat width = 0; tableViewWidth = bounds.size.width/2; width = tableViewWidth - 40; //fudge factor //CGSize textSize = {width, 20000.0f}; //width and height of text area CGSize textSize = {245.0, 20000.0f}; //width and height of text area CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap]; CGFloat ht = MAX(size1.height, 28); textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; textView.text = postData.post_body; textView.font = [UIFont systemFontOfSize:11]; textView.textAlignment = UITextAlignmentLeft; textView.textColor = [UIColor blackColor]; textView.lineBreakMode = UILineBreakModeWordWrap; textView.numberOfLines = 3; textView.autoresizesSubviews = YES; [self.contentView addSubview:imageView]; [self.contentView addSubview:textView]; [self.contentView addSubview:webView]; [self.contentView addSubview:dateTxt]; [self.contentView addSubview:headingTxt]; [self.contentView sizeToFit]; [imageView release]; [textView release]; [webView release]; [dateTxt release]; [headingTxt release]; } textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; this is the label whose height and width are going wrong.

• How to restore curropted installation?

  - by nightweels

  I have a laptop with dead battery that when there is no current connected to it turns critical so fast and in the energy management in ubuntu, when the battery is critical, there are 2 options: shutdown and hibernate witch is in grey (unclickable), so I have no choice but to chose immediate shutdown, there is no standby even if it is an option in the screen behavior. An immediate shutdown (and I mean by immediate the one that we use when we ended using the computer) happened while I was installing a program called quickly, so after the power was restored, I tried to reinstall the program then I get this translated message: An untreatable error occurred: It seems there is a software error in aptdaemon, the program that lets you install and remove software and any other task related to package management. details: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 968, in simulate trans.unauthenticated = self._simulate_helper(trans) File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1092, in _simulate_helper return depends, self._cache.required_download, \ File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 235, in required_download pm.get_archives(fetcher, self._list, self._records) SystemError: E:I wasn't able to locate a file for the libpng12-dev package.

• SharePoint 2010 Single Page Apps without a Master Page

  - by David Jacobus

  Originally posted on: http://geekswithblogs.net/djacobus/archive/2014/06/06/156827.aspxWell, maybe a stretch, but I am inclined to believe it is so.  I have been using  the JavaScript Client Object Model (JCSOM) for about 6 months now and I believe it can do about 80% of my job quickly without much fanfare.  When building sites in SharePoint no one wants the OOTB list views, etc. They want a custom look and feel!  I used to think in previous engagements that this would mean some custom server code or at least a data-form web part.   Since coming on-board in my current engagement, I have been forced because we don’t own the hosting site to come up with innovative ways to customize the UI of SharePoint.  We can push content via sandbox solutions and use JCSOM from within SharePoint Designer to do almost all customizations.  I have been using the following methodology to accomplish this: 1. Create an HTML file, which links CSS and JavaScript Files 2. Create and ASPX Web Part Page, Include a Content Editor Web Part and link to the HTML page created above.   So basically once it was done, I could copy , paste,  and rename those 4 items: CC, JS, HTML. ASPX and using MVVM just change the Model, View, and View-Model in the JavaScript file.  in about 5 minutes, I could create a completely new web part with SharePoint data.  Styling would take a little longer.  Some issues that would crop up: 1.  Multiple(s) of these web parts would not work well together on the same page (context). 2.  To separate the Web parts and context I would create a separate page for each web part and link them to a tabs layout via a Page Viewer web part or I frame.  Easy to do and not a problem but a big load problem as these web part pages even with minimal master had huge footprints.  (master page and page web part zones)   I kept thinking of my experience with SharePoint 2013 and apps!  The JavaScript was loaded from within the app, why can’t we do that in 2010 and skip the master page and web part zones. I thought at first, just link to sp.js but that didn’t work so I searched the web and found a link which did not work at all in my environment but helped me create a solution that would kudos to (Will). <!DOCTYPE html> <%@ Page %> <%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Import Namespace="Microsoft.SharePoint" %> <html> <head> <link rel="Stylesheet" type="text/css" href="../CSS/smoothness/jquery-ui-1.10.4.custom.min.css"> </head> <body > <form runat="server"> <!-- the following 5 js files are required to use CSOM --> <script src="/_layouts/1033/init.js" type="text/javascript" ></script> <script src="/_layouts/MicrosoftAjax.js" type="text/javascript" ></script> <script src="/_layouts/sp.core.js" type="text/javascript" ></script> <script src="/_layouts/sp.runtime.js" type="text/javascript" ></script> <script src="/_layouts/sp.js" type="text/javascript" ></script> <!-- include your app code --> <script src="../scripts/jquery-1.9.1.js" type="text/javascript" ></script> <script src="../Scripts/jquery-ui-1.10.3.custom.min.js" type="text/javascript"></script> <script src="../scripts/App.js" type="text/javascript" ></script> <div ID="Wrapper"> </div> <SharePoint:FormDigest ID="FormDigest1" runat="server"></SharePoint:FormDigest> </form> </body> </html> Notice that I have the scripts loaded within the body!

• Using local repository with vmbuilder and https

However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

• Mock the window.setTimeout in a Jasmine test to avoid waiting

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2014/08/21/mock-the-window.settimeout-in-a-jasmine-test-to-avoid-waiting.aspxJasmine has a clock mocking feature, but I was unable to make it work in a function that I’m calling and want to test. The example only shows using clock for a setTimeout in the spec tests and I couldn’t find a good example. Here is my current and slightly limited approach.   If we have a method we want to test: var test = function(){ var self = this; self.timeoutWasCalled = false; self.testWithTimeout = function(){ window.setTimeout(function(){ self.timeoutWasCalled = true; }, 6000); }; }; Here’s my testing code: var realWindowSetTimeout = window.setTimeout; describe('test a method that uses setTimeout', function(){ var testObject; beforeEach(function () { // force setTimeout to be called right away, no matter what time they specify jasmine.getGlobal().setTimeout = function (funcToCall, millis) { funcToCall(); }; testObject = new test(); }); afterEach(function() { jasmine.getGlobal().setTimeout = realWindowSetTimeout; }); it('should call the method right away', function(){ testObject.testWithTimeout(); expect(testObject.timeoutWasCalled).toBeTruthy(); }); }); I got a good pointer from Andreas in this StackOverflow question. This would also work for window.setInterval. Other possible approaches: create a wrapper module of setTimeout and setInterval methods that can be mocked. This can be mocked with RequireJS or passed into the constructor. pass the window.setTimeout function into the method (this could get messy)

• can I achieve my dreams without a degree? [closed]

  - by Dhananjay

  It's really giving me a lot stress as my parents saying me to join college but I don't want. I know I can learn all programming by self studying but they keep saying join college otherwise no one will give you job. I always think positive but sometimes I also start thinking like them (what if my life will be spoiled if I do not go to college) There are so much things on internet. I can learn c++, objective c, java, AI, html, php all through internet (at least I think that I can learn whole by self studying and I can give 10 hour/day easily for studying) and I will keep practicing and become a good programmer in 2 years and then try to do some job for experience so no need to waste 4 years just for studying things which I can learn in 2 years and no need to waste money on college because they teach physics, chemistry all in first 2 years and I only want to study comp. Science. But now again I am thinking negative that what will happen if I do not get degree and what will I do after learning programming if I don't get job? Please suggest what should I do? Should I join college? or self study? Can I achieve my dreams without a degree if I study hard and learn many things? I have full confidence that I can self teach myself better than they will teach in college. I will open my app company and many more. But maybe I am over confident because I don't know what happens in real world. How they treat a person without degree, etc. Anyone of you had gone through this condition? What did you do?
