  • Has anyone got "Creative Soundblaster X-Fi Surround 5.1 Pro" - (usb Interface) installed?

    - by Vivek Sharma
    Has anyone tried this external usb sound blaster on ubuntu. http://us.store.creative.com/Sound-Blaster-XFi-Surround-5.1-Pro/M/B0044DEDCA.htm. I have bought M-Audio Bx5a deluxe Studio Monitors for my T61. I think the onboard Intel HD sound card will not do any justice to these speakers. So I am looking for an external sound interface. I particularly liked this one as it is not very expensive and it has a volume control (speaker lack a central-front volume knob). Has anyone been able to use this on ubuntu. Also, if anyone would like to recommend me another option?

  • Manifestation pro logiciels libres sur un stand Microsoft, les indépendants vont-ils trop loin ?

    Manifestation pro logiciels libres sur un stand Microsoft, les indépendants vont-ils trop loin ? Chaque année, se tient à Paris le salon Solutions Linux. Un évènement dédié à l'open source, où les logiciels propriétaires ne sont guère appréciés. Microsoft, géant de l'informatique connu pour son modèle économique commercial, y vient depuis quelques années. La firme s'impliquant de plus en plus dans l'intéropérabilité, elle a en 2010 choisit de s'investir particulièrement sur ce salon en étant sponsor Gold. Une présence qui ne fut pas du goût de tout le monde dans l'assemblée. Notament, en fut très dérangée la sulfureuse équipe de la GCU Squad. Ces Gruik Coders Unis, comme ils aiment s'app...

  • MAMP Pro Uninstaller Throws "The privileged action failed." Error Even After Entering Password

    - by BigM
    I have followed, and successfully completed, every step in this SO article to remove MAMP Pro in favor of installing the free version as I only need it for one site anyway. However, when I run the uninstaller I still get "The privileged action failed." after providing the password. Can anybody shed a little light on this maybe? I'm just trying to get MAMP Pro uninstalled so I can install the free MAMP stack.

  • Hitman pro is suspicious of these three files... should I be worried?

    - by Mick
    My anti malware software "hitman pro" uses heuristics to highlight suspicious files. It is highlighting the following three, all within c:\windows\system32 mpcdx.ax rlapedec.ax rlmpcdec.ax Hitman pro has never complained about these files before. I don't know if that's because they're newly added or newly modified. Should I be worried? P.S. I recently installed erightsoft's "super" program.

  • Lenovo V570 CPU fan running constantly, CPU core 1 running over 90%!

    - by Rabbit2190
    I have seen that a lot of people are having this same issue. I am running a Lenovo V570 i5 4 core, 6 gigs of ram, and am running 11.10 Onieric Ocelot. On my system monitor graph it shows CPU at 20%, when I open the monitor it shows core #1 at around 90%, the other cores fluctuate at or below 5-12% if even. Now this seems like a really terrible balance of power between the cores, especially with so much stress on one core only, when these things are designed to work with 4 cores and not at such high temps. My current readings say 64 degrees Celsius, this does not seem normal for any cpu, and I am seriously considering, working on my windows7 partition until I see a real solution to this issue or upgrading to 12.04 right away when it comes out... I have seen countless things saying it has something to do with the Kernel, the kernel on mine is the same as when I upgraded, I really do not like messing with it, as when I had 11.04, I did tinker with it due to the freeze issues I was having, and that just made worse issues. I like this version 11.10 and would like to keep it for a while, but without the fear that my core is going to fry! So any help would be much appreciated! I did try changing a couple things in ACPI, and restarting this did not help, and here I am. I tried one thing prior to that that was listed under a different computer brand, but it would not do a make on the file. I really need help with this, I rely on this computer for a lot of things, and love this OS! Please help so I do not need to resort to my Microsoft partition! PLEASE!

  • Border image on UIView

    - by drunknbass
    I want to have a UIView subclass that has a border image, but i dont want or care about this 'new' frame/bounds around the border image itself. What i wanted to do was just use drawRect and draw outside of the rect but all drawing is clipped and i dont see a way to not clip drawing outside of this context rect. So now i have added a sublayer to the views layer, set [self clipsToBounds] on the view and override setFrame to control my sublayers frame and always keep it at the proper size (spilling over the views frame by 40px) the problem with this is that setFrame on a uiview by default has no animation but seTFrame on a calayer does. i cant just disable the animations on the calayers setFrame because if i were to call setFrame on the uiview inside a uiview animation block the calayer would still have its animation disabled. the obvious solution is to look up the current animationDuration on the uiview animation and set a matching animation on the sublayer, but i dont know if this value is available. And even if it is, im afraid that calling an animation from within another animation is wrong. Unfortunately the best solution is to not use a calayer at all and just add a uiview as a subview and draw into that just like i am drawing into my layer, and hope that with autoresizingMask set to height and width that everything will 'just work'. Just seems like unnecessary overhead for such a simple task.

  • NSFetchedResultsController crashing on performFetch: when using a cache

    - by Oliver
    I make use of NSFetchedResultsController to display a bunch of objects, which are sectioned using dates. On a fresh install, it all works perfectly and the objects are displayed in the table view. However, it seems that when the app is relaunched I get a crash. I specify a cache when initialising the NSFetchedResultsController, and when I don't it works perfectly. Here is how I create my NSFetchedResultsController: - (NSFetchedResultsController *)results { // If we are not nil, stop here if (results != nil) return results; // Create the fetch request, entity and sort descriptors NSFetchRequest *fetch = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:self.managedObjectContext]; NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"utc_start" ascending:YES]; NSArray *descriptors = [[NSArray alloc] initWithObjects:descriptor, nil]; // Set properties on the fetch [fetch setEntity:entity]; [fetch setSortDescriptors:descriptors]; // Create a fresh fetched results controller NSFetchedResultsController *fetched = [[NSFetchedResultsController alloc] initWithFetchRequest:fetch managedObjectContext:self.managedObjectContext sectionNameKeyPath:@"day" cacheName:@"Events"]; fetched.delegate = self; self.results = fetched; // Release objects and return our controller [fetched release]; [fetch release]; [descriptor release]; [descriptors release]; return results; } These are the messages I get when the app crashes: FATAL ERROR: The persistent cache of section information does not match the current configuration. You have illegally mutated the NSFetchedResultsController's fetch request, its predicate, or its sort descriptor without either disabling caching or using +deleteCacheWithName: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'FATAL ERROR: The persistent cache of section information does not match the current configuration. You have illegally mutated the NSFetchedResultsController's fetch request, its predicate, or its sort descriptor without either disabling caching or using +deleteCacheWithName:' I really have no clue as to why it's saying that, as I don't believe I'm doing anything special that would cause this. The only potential issue is the section header (day), which I construct like this when creating a new object: // Set the new format [formatter setDateFormat:@"dd MMMM"]; // Set the day of the event [event setValue:[formatter stringFromDate:[event valueForKey:@"utc_start"]] forKey:@"day"]; Like I mentioned, all of this works fine if there is no cache involved. Any help appreciated!

  • What causes this error? "CALayer position contains NaN: [240 nan]"

    - by Kevlar
    I've seen this happen whenever i rotate a screen that has a UITableView on it. I've found out that it happens inbetween the willRotate and didRotate method calls in UIViewController My co-workers have seen it in other spots as well, usually around rotation. It hadnt started happening until very recently, and we're stumped as to how we should deal with it (google searches don't turn up the error message in its exact form). Has anyone else encountered this that knows what to do about it?

  • Animating a custom property of CALayer subclass

    - by jemmons
    I have a CALayer subclass, MyLayer, that has a NSInteger property called myInt. I'd really like to animate this property via CABasicAnimation, but it seems CABasicAnimation only works on so-called "animatable" properties (bounds, position, etc). Is there something I can override to make my custom myInt property animatable?

  • iPhone crash on CoreData save

    - by davetron5000
    This is a different situation than this question, as the solution provided doesn't work and the stack is different. Periodical crash when I save data using coredata. The stack trace isn't 100% clear on where this is happening, but I'm certain it's this routine that's being called. It's either the save: in this method or the one following. Code: -(void)saveWine { if ([self validInfo]) { Wine *wine = (Wine *)wineToEdit; if (wine == nil) { wine = (Wine *)[NSEntityDescription insertNewObjectForEntityForName:@"Wine" inManagedObjectContext:self.managedObjectContext]; } wine.uuid = [Utils createUUID]; wine.name = self.wineNameField.text; wine.vineyard = self.vineyardField.text; wine.vintage = [[self numberFormatter] numberFromString:self.vintageField.text]; wine.timeStamp = [NSDate date]; wine.rating = [NSNumber numberWithInt:self.ratingControl.selectedSegmentIndex]; wine.partnerRating = [NSNumber numberWithInt:self.partnerRatingControl.selectedSegmentIndex]; wine.varietal = self.currentVarietal; wine.tastingNotes = self.currentTastingNotes; wine.dateTasted = self.currentDateTasted; wine.tastingLocation = [[ReferenceDataAccessor defaultReferenceDataAccessor] addEntityForType:TASTING_LOCATION withName:self.currentWhereTasted]; id type = [[ReferenceDataAccessor defaultReferenceDataAccessor] entityForType:WINE_TYPE withOrdinal:self.typeControl.selectedSegmentIndex]; wine.type = type; NSError *error; NSLog(@"Saving %@",wine); if (![self.managedObjectContext save:&error]) { [Utils showAlertMessage:@"There was a problem saving your wine; try restarting the app" withTitle:@"Problem saving"]; NSLog(@"Error while saving new wine %@, %@", error, [error userInfo]); } } else { NSLog(@"ERROR - someone is calling saveWine with invalid info!!"); } } Code for addEntityForType:withName:: -(id)addEntityForType:(NSString *)type withName:(NSString *)name { if ([Utils isStringBlank:name]) { return nil; } id existing = [[ReferenceDataAccessor defaultReferenceDataAccessor] entityForType:type withName:name]; if (existing != nil) { NSLog(@"%@ with name %@ already exists",type,name); return existing; } NSManagedObject *newEntity = [NSEntityDescription insertNewObjectForEntityForName:type inManagedObjectContext:self.managedObjectContext]; [newEntity setValue:name forKey:@"name"]; NSError *error; if (![self.managedObjectContext save:&error]) { [Utils showAlertMessage:[NSString stringWithFormat:@"There was a problem saving a %@",type] withTitle:@"Database Probem"]; [Utils logErrorFully:error forOperation:[NSString stringWithFormat:@"saving new %@",type ]]; } return newEntity; } Stack trace: Thread 0 Crashed: 0 libSystem.B.dylib 0x311de2d4 __kill + 8 1 libSystem.B.dylib 0x311de2c4 kill + 4 2 libSystem.B.dylib 0x311de2b6 raise + 10 3 libSystem.B.dylib 0x311f2d72 abort + 50 4 libstdc++.6.dylib 0x301dea20 __gnu_cxx::__verbose_terminate_handler() + 376 5 libobjc.A.dylib 0x319a2594 _objc_terminate + 104 6 libstdc++.6.dylib 0x301dcdf2 __cxxabiv1::__terminate(void (*)()) + 46 7 libstdc++.6.dylib 0x301dce46 std::terminate() + 10 8 libstdc++.6.dylib 0x301dcf16 __cxa_throw + 78 9 libobjc.A.dylib 0x319a14c4 objc_exception_throw + 64 10 CoreData 0x3526e83e -[NSManagedObjectContext save:] + 1098 11 Wine Brain 0x0000651e 0x1000 + 21790 12 Wine Brain 0x0000525c 0x1000 + 16988 13 Wine Brain 0x00004894 0x1000 + 14484 14 Wine Brain 0x00008716 0x1000 + 30486 15 CoreFoundation 0x31477fe6 -[NSObject(NSObject) performSelector:withObject:withObject:] + 18 16 UIKit 0x338c14a6 -[UIApplication sendAction:to:from:forEvent:] + 78 17 UIKit 0x3395c7ae -[UIBarButtonItem(UIInternal) _sendAction:withEvent:] + 86 18 CoreFoundation 0x31477fe6 -[NSObject(NSObject) performSelector:withObject:withObject:] + 18 19 UIKit 0x338c14a6 -[UIApplication sendAction:to:from:forEvent:] + 78 20 UIKit 0x338c1446 -[UIApplication sendAction:toTarget:fromSender:forEvent:] + 26 21 UIKit 0x338c1418 -[UIControl sendAction:to:forEvent:] + 32 22 UIKit 0x338c116a -[UIControl(Internal) _sendActionsForEvents:withEvent:] + 350 23 UIKit 0x338c19c8 -[UIControl touchesEnded:withEvent:] + 336 24 UIKit 0x338b734e -[UIWindow _sendTouchesForEvent:] + 362 25 UIKit 0x338b6cc8 -[UIWindow sendEvent:] + 256 26 UIKit 0x338a1fc0 -[UIApplication sendEvent:] + 292 27 UIKit 0x338a1900 _UIApplicationHandleEvent + 5084 28 GraphicsServices 0x35d66efc PurpleEventCallback + 660 29 CoreFoundation 0x314656f8 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 20 30 CoreFoundation 0x314656bc __CFRunLoopDoSource1 + 160 31 CoreFoundation 0x31457f76 __CFRunLoopRun + 514 32 CoreFoundation 0x31457c80 CFRunLoopRunSpecific + 224 33 CoreFoundation 0x31457b88 CFRunLoopRunInMode + 52 34 GraphicsServices 0x35d664a4 GSEventRunModal + 108 35 GraphicsServices 0x35d66550 GSEventRun + 56 36 UIKit 0x338d5322 -[UIApplication _run] + 406 37 UIKit 0x338d2e8c UIApplicationMain + 664 38 Wine Brain 0x000021ba 0x1000 + 4538 39 Wine Brain 0x00002184 0x1000 + 4484 I have no idea why my app's memory locations aren't being symbolocated, but the code paths lead to only two manavedObjectContext save: calls. The time this happend, addEntityForType was called all the way through, creating a new object for the "whereTasted" entity, before the final save: on the entire wine object. When I go through the same procedure again, it works fine. This leads me to believe it's something to do with the app having been run for a while when adding a new location, but I'm not sure. Any thoughts on how I can debug this and get more info the next time this happens?

  • iPhone NSDate - get time in milliseconds and store in coredata

    - by satyam
    I'm implementing iphone app with coredata functionality. I've an attribute in entity "NSDate" which stores the date and time when the record is added. I'm adding records at a faster rate. About 1 record per 25 milli seconds I want to store the date along with milli seconds so that I can retrieve the data in descending order. How can I do this?

  • Why might changes be populated from one NSManagedObjectContext to another without an explicit merge?

    - by Mike Laurence
    I'm working on an object import feature that utilizes multiple threads/NSManagedObjectContexts, using http://www.mac-developer-network.com/columns/coredata/may2009/ as my guide (note that I am developing for iPhone). For some reason, when I save one of my contexts the other is immediately updated with the changes, even though I have commented out my calls to mergeChangesFromContextDidSaveNotification. Are there any reasons the contexts might be merging into one another without an explicit call? Here a log of what's going on: // 1.) Main context is saved with "Peter Gabriel" // 2.) Test context is created, begins with same contents as main context // 3.) Main context is inserted with "Spoon" // 4.) Test context is inserted with "Phoenix" // Contents at this point: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) // 5.) testContext is saved // New contents of contexts: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Phoenix", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) As you can see, the test context is saved midway through, and the main context suddenly has the new objects from the test context, even though I haven't performed the whole NSManagedObjectContextDidSaveNotification/mergeChangesFromContext combo. My understanding is that no changes will ever be merged unless done so explicitly... does anyone know what's going on here?

  • Blind down animation on CALayer using a mask

    - by dgjones346
    Hi there, I want to create a "blind down" effect on an image so the image "blinds down" and appears. Sort of like this JavaScript transition: http://wiki.github.com/madrobby/scriptaculous/effect-blinddown The mask is setup correctly because if I manually change it's position it hides and reveals the image behind it, but it doesn't animate! It just ends up in the animates final position and you never see it actual blind. Please help! Maybe this isn't the best way to achieve a blind down effect? // create a new layer CALayer *numberLayer = [[CALayer alloc] init]; // render the number "7" on the layer UIImage *image = [UIImage imageNamed:@"number-7.png"]; numberLayer.contents = (id) [image CGImage]; numberLayer.bounds = CGRectMake(0, 0, image.size.width, image.size.height); // width and height are 50 numberLayer.position = position; // create a new mask that is 50x50 the size of the image CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init]; CGMutablePathRef path = CGPathCreateMutable(); CGPathAddRect(path, nil, CGRectMake(0, 0, 50, 50)); [maskLayer setPath:path]; [maskLayer setFillColor:[[UIColor whiteColor] CGColor]]; [theLayer setMask:maskLayer]; [maskLayer setPosition:CGPointMake(0, 0)]; // place the mask over the image [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:3.0]; [maskLayer setPosition:CGPointMake(0, 50)]; // slide mask off the image // this should shift the blind away in an animation // but it doesn't animate [UIView commitAnimations]; [maskLayer release]; [boardLayer addSublayer:numberLayer]; [numberLayer release];

  • CGContextDrawPDFPage taking up large amounts of memory

    - by Ed Marty
    I have a PDF file that I want to draw in outline form. I want to draw the first several pages on the document each in their own UIImage to use on a button so that when clicked, the main display will navigate to the clicked page. However, CGContextDrawPDFPage seems to be using copious amounts of memory when attempting to draw the page. Even though the image is only supposed to be around 100px tall, the application crashes while drawing one page in particular, which according to Instruments, allocates about 13 MB of memory just for the one page. Here's the code for drawing: //Note: This is always called in a background thread, but the autorelease pool is setup elsewhere + (void) drawPage:(CGPDFPageRef)m_page inRect:(CGRect)rect inContext:(CGContextRef) g { CGPDFBox box = kCGPDFMediaBox; CGAffineTransform t = CGPDFPageGetDrawingTransform(m_page, box, rect, 0,YES); CGRect pageRect = CGPDFPageGetBoxRect(m_page, box); //Start the drawing CGContextSaveGState(g); //Clip to our bounding box CGContextClipToRect(g, pageRect); //Now we have to flip the origin to top-left instead of bottom left //First: flip y-axix CGContextScaleCTM(g, 1, -1); //Second: move origin CGContextTranslateCTM(g, 0, -rect.size.height); //Now apply the transform to draw the page within the rect CGContextConcatCTM(g, t); //Finally, draw the page //The important bit. Commenting out the following line "fixes" the crashing issue. CGContextDrawPDFPage(g, m_page); CGContextRestoreGState(g); } Is there a better way to draw this image that doesn't take up huge amounts of memory?

  • Load CoreData objects' string property into UIPickerView

    - by OscarTheGrouch
    Hello Currently I have an entity named "Events" in a CoreData app. "Events" has one string property named "eventName". In the -(void)viewDidLoad I am trying to Fetch all the "Events" objects and load their "eventName" by alphabetical order into a UIPickerView. The ultimate end goal is through the use of a textField, buttons and the pickerView being add new objects in and remove unwanted objects out. Basically turning the UIPickerView into a UITableView. Currently I am able to save objects to the CoreData store, but am not able to pull them/their properties out into the UIPickerView. I am willing and able to share the project source code to anyone who wants it, or is willing to look at it to help out. thanks Chris

  • Reasons for NSManagedObjectMergeError error on [NSManagedObjectContext save:]

    - by ross-kimes
    I have a application that combines threading and CoreData. I and using one global NSPersistentStoreCoordinator and a main NSManagedObjectContextModel. I have a process where I have to download 9 files simultaneously, so I created an object to handle the download (each individual download has its own object) and save it to the persistentStoreCoordinator. In the [NSURLConnection connectionDidFinishLoading:] method, I created a new NSManagedObject and attempt to save the data (which will also merge it with the main managedObjectContext). I think that it is failing due to multiple process trying to save to the persistentStoreCoordinator at the same time as the downloads are finishing around the same time. What is the easiest way to eliminate this error and still download the files independently? Thank you!

  • iPhone Mapkit Blue Dot / User Location Region Zoom Question

    - by user290031
    Hey All, Is is possible to set a region based on a current location in a mapview only one time. I want my iphone app to get the current location, zoom into that current location, and then allow the user to scroll around. However, because my setRegion code is in my didUpdateToLocation function, every time the current location is updated, so is the region, and I can't scroll around on the map. I tried putting this setRegion code in the viewDidLoad function, but the user's current location isn't initialized at this point, so it doesn't work right. Any ideas?

  • Expand and Shrink UIScrollView with animation

    - by Dilip Rajkumar
    I am having a UITableView inside a scrollview. So I am trying to do a accordion like component using UITableView. So I need to expand the UITableView to add more cell. In that case I have to increase the height of UIScrollView with a animation so that it matches the table animation. - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSInteger row = [indexPath row]; BOOL preventReopen = NO; if (row == expandedRowIndex + 1 && expandedRowIndex != -1) return nil; [tableView beginUpdates]; if (expandedRowIndex != -1) { familyTableView.frame = CGRectMake(familyTableView.frame.origin.x, familyTableView.frame.origin.y, familyTableView.frame.size.width, 3*50+22); toolsTableView.frame = CGRectMake(toolsTableView.frame.origin.x, familyTableView.frame.origin.y + familyTableView.frame.size.height + 20, toolsTableView.frame.size.width, 4*50+22); myAccountTableView.frame = CGRectMake(myAccountTableView.frame.origin.x, toolsTableView.frame.origin.y + toolsTableView.frame.size.height + 20, myAccountTableView.frame.size.width, 2*50+22); settingsScrollView.contentSize = CGSizeMake(320, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380); settingsScrollView.contentInset = UIEdgeInsetsMake(0, 0, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380, 0); NSInteger rowToRemove = expandedRowIndex + 1; preventReopen = row == expandedRowIndex; if (row > expandedRowIndex) row--; expandedRowIndex = -1; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:rowToRemove inSection:0]] withRowAnimation:UITableViewRowAnimationTop]; }else { familyTableView.frame = CGRectMake(familyTableView.frame.origin.x, familyTableView.frame.origin.y, familyTableView.frame.size.width, (3*50+22) + 100); toolsTableView.frame = CGRectMake(toolsTableView.frame.origin.x, familyTableView.frame.origin.y + familyTableView.frame.size.height + 20, toolsTableView.frame.size.width, 4*50+22); myAccountTableView.frame = CGRectMake(myAccountTableView.frame.origin.x, toolsTableView.frame.origin.y + toolsTableView.frame.size.height + 20, myAccountTableView.frame.size.width, 2*50+22); settingsScrollView.contentSize = CGSizeMake(320, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380); settingsScrollView.contentInset = UIEdgeInsetsMake(0, 0, familyTableView.frame.size.height + toolsTableView.frame.size.height+ myAccountTableView.frame.size.height + 380, 0); } NSInteger rowToAdd = -1; if (!preventReopen) { rowToAdd = row + 1; expandedRowIndex = row; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:rowToAdd inSection:0]] withRowAnimation:UITableViewRowAnimationTop]; } [tableView endUpdates]; return nil; } I am not good at animation. Any help is greatly appreciated. What I need is when we do [tableView beginUpdates] we have to start animating the resize effect to UIScrollView and it should end when [tableView endUpdates] executes. So the Accordion executes flawlessly. Thanks in advance for any help..
