  • Big trouble after app update. CoreData migration error

    - by MrBr
    this morning we had a big trouble with our iphone app. We had to even take it off the store. The thing is that we made real small changes to our xcdatamodel. We thought that the update process is automatically taking care about exchanging it the right way until we found out something like CoreData migration exists. We are using the UIManagedDocument to connect to the persistent store. How is it possible to exchange this file with the new one? While we were developing we just uninstalled the whole app from the device and then installed it again and everything worked. How can we simulate this process in the app store with updates? UPDATE I try to set the migration option like this _database = [[UIIManagedDocument alloc] init]; NSMutableDictionary *options = [[NSMutableDictionary alloc] init]; [options setObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption], _database.persistentStoreOptions = options; but the app is still crashing with ** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'This NSPersistentStoreCoordinator has no persistent stores. It cannot perform a save operation.'

  • Magento, NGINX, PHP-FPM, APC, MEMCACHED, 16gb Ram CentOS, Spiking PHP-FPM to 100% CPU

    - by Terry Dunford
    I have been trying to resolve my issue of spiking cpu caused by php-fpm processes. I've reduced the php-fpm config settings to: pm = ondemand pm.max_children = 12 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 10 pm.max_requests = 500 php_admin_value[memory_limit] = 128M Problem still exists. I'm running a Joomla main site (which is having no problems) and a Magento store in a sub-directory. My server is a Linux CentOS, running NGINX, APC, Memcached, Full Page Cache and php-fpm. My server has 8 cores and 16gb dedicated ram. My host has shut down my server several times the past week because my php-fpm processes are consuming the entire network. A lot of the individual php-fpm processes are getting over 50% cpu. I've hired several "professionals" and none of them was able to help me, so now broke and stumped, I'm turning to you guys for help. So any suggestions would be greatly appreciated. I turned on slow php logs and here are some of the latest results: [01-Apr-2012 14:26:12] [pool magento] pid 21537 script_filename = /home/flyfish/www/flyshop/index.php [0x0000000011a394f8]

  • Software Architecture and MEF composition location

    - by Leonardo
    Introduction My software (a bunch of webapi's) consist of 4 projects: Core, FrontWebApi, Library and Administration. Library is a code library project that consists of only interfaces and enumerators. All my classes in other projects inherit from at least one interface, and this interface is in the library. Generally speaking, my interfaces define either Entities, Repositories or Controllers. This project references no other project or any special dlls... just the regular .Net stuff... Core is a class-library project where concrete implementation of Entities and Repositories. In some cases i have more than 1 implementation for a Repository (ex: one for azure table storage and one for regular Sql). This project handles the intelligence (business rules mostly) and persistence, and it references only the Library. FrontWebApi is a ASP.NET MVC 4 WebApi project that implements the controllers interfaces to handle web-requests (from a mobile native app)... It references the Core and the Library. Administration is a code-library project that represents a "optional-module", meaning: if it is present, it provides extra-features (such as Access Control Lists) to the application, but if its not, no problem. Administration is also only referencing the Library and implementing concrete classes of a few interfaces such as "IAccessControlEntry"... I intend to make this available with a "setup" that will create any required database table or anything like that. But it is important to notice that the Core has no reference to this project... Development Now, in order to have a decoupled code I decide to use IoC and because this is a small project, I decided to do it using MEF, specially because of its advertised "composition" capabilities. I arranged all the imports/exports and constructors and everything, but something is quite not perfect in my "mental-visualisation": Main Question Where should I "Compose" the objects? I mean: Technically, the only place where real implementation access is required is in the Repositories, because in order to retrieve data from wherever, entities instances will be necessary, and in all other places. The repositories could also provide a public "GetCleanInstanceOf()" right? Then all other places will be just fine working with the interfaces instead of concrete classes... Secondary Question Should "Administration" implement the concrete object for "IAccessControlGeneralRepository" or the Core should?

  • Intel® Core™2 Duo Desktop Processor vs Intel® Core™ i3 Desktop Processor?

    - by metal gear solid
    Intel® Core™2 Duo Desktop Processor vs Intel® Core™ i3 Desktop Processor? Which CPU is better to buy ? Intel® Core™ i3-530 Processor (4M Cache, 2.93 GHz) (it supports DDR3 also) or Intel® Core™2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB) (it supports DDR2 only ) Although I do not play games on my PC but I need good performance in Adobe Photoshop, Watching Full HD Movies. I need good performance in Multitasking. Along with any of these CPU I would purchase 2 GB x 2 stick of RAM. and I will use Windows 7. and I will use Microsoft VPC images also with MS Virtual PC.

  • What does the "Max Memory Size" on the new Intel Core i3 / i5 / i7 CPU's mean?

    - by Josh
    I just noticed in the specs of the new Intel Core i-series processors that there is a "Max Memory Size" that is usually pretty small -- anywhere from 8GB to 24GB. See here: http://ark.intel.com/Product.aspx?id=41316 Core 2-based motherboards were just starting to roll out support for 32GB and greater memory sizes. Anyone have any idea what the Max Memory Size indicates? Is this the total limitation of the on-chip memory controller? Limitation per channel? Limitation per stick (e.g. density??)? Thinking of building a decent machine that needs lots of RAM, so I'm looking at the i7 860.

  • Code structure for multiple applications with a common core

    - by Azrael Seraphin
    I want to create two applications that will have a lot of common functionality. Basically, one system is a more advanced version of the other system. Let's call them Simple and Advanced. The Advanced system will add to, extend, alter and sometimes replace the functionality of the Simple system. For instance, the Advanced system will add new classes, add properties and methods to existing Simple classes, change the behavior of classes, etc. Initially I was thinking that the Advanced classes simply inherited from the Simple classes but I can see the functionality diverging quite significantly as development progresses, even while maintaining a core base functionality. For instance, the Simple system might have a Project class with a Sponsor property whereas the Advanced system has a list of Project.Sponsors. It seems poor practice to inherit from a class and then hide, alter or throw away significant parts of its features. An alternative is just to run two separate code bases and copy the common code between them but that seems inefficient, archaic and fraught with peril. Surely we have moved beyond the days of "copy-and-paste inheritance". Another way to structure it would be to use partial classes and have three projects: Core which has the common functionality, Simple which extends the Core partial classes for the simple system, and Advanced which also extends the Core partial classes for the advanced system. Plus having three test projects as well for each system. This seems like a cleaner approach. What would be the best way to structure the solution/projects/code to create two versions of a similar system? Let's say I later want to create a third system called Extreme, largely based on the Advanced system. Do I then create an AdvancedCore project which both Advanced and Extreme extend using partial classes? Is there a better way to do this? If it matters, this is likely to be a C#/MVC system but I'd be happy to do this in any language/framework that is suitable.

  • How to associate Wi-Fi beacon info with a virtual "location"?

    - by leander
    We have a piece of embedded hardware that will sense 802.11 beacons, and we're using this to make a map of currently visible bssid -> signalStrength. Given this map, we would like to make a determination: Is this likely to be a location I have been to before? If so, what is its ID? If not, I should remember this location: generate a new ID. Now what should I store (and how should I store it) to make future determinations easier? This is for an augmented-reality app/game. We will be using it to associate particular characters and events with "locations". The device does not have internet or cellular access, so using a geolocation service is out of consideration for the time being. (We don't really need to know where we are in reality, just be able to determine if we return there.) It isn't crucial that it be extremely accurate, but it would be nice if it was tolerant to signal strength changes or the occasional missing beacon. It should be usable in relatively low numbers of access points (e.g. rural house with one wireless router) or many (wandering around a dense metropolis). In the case of a city, it should change location every few minutes of walking (continuously-overlapping signals make this a bit more tricky in naive code). A reasonable number of false positives (match a location when we aren't actually there) is acceptable. The wrong character/event showing up just adds a bit of variety. False negatives (no location match) are a bit more troublesome: this will tend to add a better-matching new location to the saved locations, masking the old one. While we will have additional logic to ensure locations that the device hasn't seen in a while will "orphan" any associated characters or events (if e.g. you move to a different country), we'd prefer not to mask and eventually orphan locations you do visit regularly. Some technical complications: signalStrength is returned as 1-4; presumably it's related to dB, but we are not sure exactly how; in my experiments it tends to stick to either 1 or 4, but occasionally we see numbers in between. (Tech docs on the hardware are sparse.) The device completes a scan of one-quarter of the channel space every second; so it takes about 4-5 seconds to get a complete picture of what's around. The list isn't always complete. (We are making strides to fix this using some slight sampling period randomization, as recommended by the library docs. We're also investigating ways to increase the number of scans without killing our performance; the hardware/libs are poorly behaved when it comes to saturating the bus.) We have only kilobytes to store our history. We have a "working" impl now, but it is relatively naive, and flaky in the face of real-world Wi-Fi behavior. Rough pseudocode: // recordLocation() -- only store strength 4 locations m_savedLocations[g_nextId++] = filterForStrengthGE( m_currentAPs, 4 ); // determineLocation() bestPoints = -inf; foreach ( oldLoc in m_savedLocations ) { points = 0.0; foreach ( ap in m_currentAPs ) { if ( oldLoc.has( ap ) ) { switch ( ap.signalStrength ) { case 3: points += 1.0; break; case 4: points += 2.0; break; } } } points /= oldLoc.numAPs; if ( points > bestPoints ) { bestLoc = oldLoc; bestPoints = points; } } if ( bestLoc && bestPoints > 1.0 ) { if ( bestPoints >= (2.0 - epsilon) ) { // near-perfect match. // update location with any new high-strength APs that have appeared bestLoc.addAPs( filterForStrengthGE( m_currentAPs, 4 ) ); } return bestLoc; } else { return NO_MATCH; } We record a location currently only when we have NO_MATCH and the app determines it's time for a new event. (The "near-perfect match" code above would appear to make it harder to match in the future... It's mostly to keep new powerful APs from being associated with other locations, but you'd think we'd need something to counter this if e.g. an AP doesn't show up in the next 10 times I match a location.) I have a feeling that we're missing some things from set theory or graph theory that would assist in grouping/classification of this data, and perhaps providing a better "confidence level" on matches, and better robustness against missed beacons, signal strength changes, and the like. Also it would be useful to have a good method for mutating locations over time. Any useful resources out there for this sort of thing? Simple and/or robust approaches we're missing?

  • Nginx Browser Caching using HTTP Headers outside server/location block

    - by Danny O'Sullivan
    I am having difficulty setting the HTTP expires headers for Nginx outside of specific server (and then location) blocks. What I want is to something like the following: location ~* \.(png|jpg|jpeg|gif|ico)$ { expires 1y; } But not have to repeat it in every single server block, because I am hosting a large number of sites. I can put it in every server block, but it's not very DRY. If I try to put that into an HTTP block or outside of all other blocks, I get "location directive is not allowed here." It seems I have to put it into a server block, and I have a different server block for every virtual host. Any help/clarification would be appreciated.

  • Location, Orientation, and Writing a Custom Control with Mono for Android, .NET, and C#

    - by Wallym
    Like real estate, mobile is about location, location, location. That means that direction is an important item. And just as important is how this information is presented to the user. In Nov. 2011, we talked about building a user interface in Mono For Android. In this article, I'll expand a little bit on that by creating a compass that displays north. We'll use Android's built-in sensor support to determine the orientation of the device, then use a custom control to display North. The output will look like

  • Finding closest object to a location within a specific perpendicular distance to direction vector

    - by Sniper
    I have a location and a direction vector indicating facing, I want to find the closest object to that location that is within some tolerance distance (perpendicular distance) to the ray formed by the location and direction vector. Basically I want to get the object that is being aimed at. I have thought about finding all objects within a box and then finding the closest object to my vector from them results, but I am sure that there is a more efficient way. The Z axis is optional, the objects are most likely within a few meters of the search vector.

  • .NET mulithreading and quad core processors

    - by w0051977
    I have a single threaded application that runs on a machine with a quad core processor. The scheduled tasks that run VB.NET forms are too slow. I am new to multi threading and parallel computing. If you have a single threaded application that runs on a server with a multi core processor then does the application only ever use one of the processors? What happens if you have multiple scheduled tasks and multiple instances are in memory at the same time? I have read this question on Stackoverflow: http://stackoverflow.com/questions/607775/how-to-write-net-applications-that-utilize-multi-core-processors, but I am still not clear.

  • Is the Intel Core i5 mobile processor better than the Intel Core i7 mobile processor?

    - by Tim Barnaski
    I'm shopping for a new laptop from Dell (going to install Ubuntu on it) and I'm currently trying to sort out which processor I want. Based purely on the clock speed, it would seem that the core i5 is better than the core i7. The Intel® Core™ i5-430M has a 2.26GHz clock speed, while the Intel® Core™ i7-720QM Quad Core Processor only has a 1.6GHz clock speed. Would this not indicate that the i5 is faster than the i7?

  • How to get remote firewall administration working with Windows Server Core 2008 R2?

    - by Daniel15
    I'm setting up a Windows Server Core 2008 R2 installation in a VMware virtual machine before setting it up on a live VPS. I've gotten remote administration via MMC working on my computer (a PC running Windows 7) for things like event logs, but I can't seem to get the firewall administration working. No matter what I do, I get the following error mesage: You do not have the correct permissions to open the Windows Firewall with Advanced Security console. You must be a member of the Administrators group or the Network Operators group to perform this task. For more information, contact you system administrator. Error code: 0x5. I've used cmdkey to add valid server credentials on my computer, and enabled remote management with the following commands: netsh advfirewall firewall set rule group="remote administration" new enable=yes netsh advfirewall firewall set rule group="windows firewall remote management" new enable=yes netsh advfirewall set currentprofile settings remotemanagement enable I am not running on a domain (just a workgroup), this is the only Windows Server 2008 computer I have. I've tried turning off the firewall completely, but remote administration is still failing How do I debug this issue? Does anyone know how to fix it? I found a few forum topics about it (eg. Remotely managing Windows Firewall on Server Core gives access denied (error 0x5) on Windows Server TechCenter) but they didn't help (I've already tried most of the fixes listed).

  • New i7 is slower than old Core 2 Duo? Why? (BIOS programming)

    - by DrChase
    I've always wondered why the companies who make BIOS' either have terrible engineering psychologists or none at all. But without wasting your time further with random speculative questions, my real question is as follows: Why does my new computer run slower than my old computer? Old Computer: Intel Core 2 Duo CPU @ 3.0 Ghz (stock) 4GB OCZ DDR2 800 RAM Wolfdale E8400 mb nVidia GeForce 8600 GT New Computer: Intel Core i7 920 @ ~3.2 Ghz 6 GB OCZ DDR3 1066 RAM EVGA x58 SLI LE motherboard nVidia GeForce GTX 275 Vista x64 Home Premium on both. "Run slower" is defined as: - poorer FPS performance in the same games, applications - takes longer to start up - general desktop usage (checking email, opening up files, running exe's) is noticeably slower At first I thought I must've not set something up in the BIOS or something. But I have no idea how to set anything in the bios except for "Dummy O.C.", which brought me to ~3.2 Ghz. But beyond that I have no idea. I've been reading stuff about "ram timing" and voltages and the like but I really have no idea about that stuff. I'm a psychologist who has a basic understanding in building his own computers, not a computer scientist. Can someone give me some wisdom that might guide me to the reason my new computer is worse than my older one? I'm sorry if this is a bad question, or not appropriate to SO. I'm just pretty frustrated now and you all have helped me in the past so I figured I'd give it a shot. Thanks for your time.

  • Why does Adding Core Animation slow down drawing of my NSTableView?

    - by Will Goring
    I have a simple App that displays a list of items using NSTableView. There are usually about 15-25 items in the list, and the table has 10 columns, all but one of which are text (the other's an icon.) There are simple data transformers on a couple of the columns. So nothing taxing; you'd expect it to run just fine. And as it stands, it is; the app is responsive and everything draws pretty much instantly. Scrolling, changing column sizes, resizing the window; whatever you do the redraws keep up with the mouse-pointer. Tonight, I thought I'd try adding a little visual flair to the app with Core Animation (which I've never used before,) but I've found that if anything above the NSTableView in the hierarchy is set 'Wants Core Animation Layer,' then the NSTableView redraws go to hell. Scrolling is usually fine, but resizing columns or the window causes it to pick up an effect like texture tearing, where some of the rows have the new size, and some have the old one, and everything flickers horribly. It looks terrible. Basically it looks like what you'd expect if rendering the individual rows or columns was taking a long time. I've put it through Shark and, sure enough, it looks like it's spending most of its time drawing the text in the cells; what I don't understand is why that should take longer when there's a Core Animation layer involved than when there isn't - and quite noticeably longer at that. Has anyone got any ideas? Is there any Core Animation initialisation or config I've missed or something (I've literally just ticked the "Wants Core Animation Layer" box in IB)? Cheers, Will

  • Core Data - How to check if a managed object's properties have been deallocated?

    - by georryan
    I've created a program that uses core data and it works beautifully. I've since attempted to move all my core data methods calls and fetch routines into a class that is self contained. My main program then instantiates that class and makes some basic method calls into that class, and the class then does all the core data stuff behind the scenes. What I'm running into, is that sometimes I'll find that when I grab a managed object from the context, I'll have a valid object, but its properties have been deallocated, and I'll cause a crash. I've played with the zombies and looked for memory leaks, and what I have gathered is it seems that the run loop is probably responsible for deallocating the memory, but I'm not sure. Is there a way to determine if that memory has been deallocated and force the core data to get it back if I need to access it? My managedObjectContext never gets deallocated, and the fetchedResultsController never does, either. I thought maybe I needed to use the [managedObjectContext refreshObject:mergeData:] method, or the [managedObjectContext setRetainsRegisteredObjects:] method. Although, I'm under the impression that last one may not be the best bet since it will be more memory intensive (from what I understand). These errors only popped up when I moved the core data calls into another class file, and they are random when they show up. Any insight would be appreciated. -Ryan

  • Any chance to get Core Data using Tokyo Cabinet as the persistent store?

    - by dontWatchMyProfile
    I watched a free high quality video with Aaron Hillegass about Core Data vs Tokyo Cabinet. Besides that this guy is amazingly funny (really, if you want to laugh now, watch it!), he shows off Tokyo Cabinet beeing about 40x faster than Core Data. I wonder if it's worth thinking about how to attach this to Core Data? Does that make any sense? Maybe as a custom atomic store or something like this?

  • Core Data: Overkill for simple, static UITableView-based iPhone App?

    - by David Foster
    Hello! I have a rather simple iPhone app consisting of numerous views containing a single, grouped table view. These views are held together in navigation controllers which are grouped in a tab bar. Simple stuff. My table views do little more than list text (like "Dog", "Cat" and "Weasel") and this data is being served from a collection of plists. It's perhaps worth mentioning too that these tables are 'static' in the sense that their data is pre-determined and will only ever be amended—and if so, very rarely indeed—by the developer (in this case, moi). This rudimentary approach has reached its limits though, and I think I'm going to need something a bit more relational. I have worked a tad with Core Data in the past, but only with apps whose data is determined by user input. I have four closely related questions: Is Core Data overkill for an app consisting mainly of a selection of simple table views? Do you recommend using Core Data to manage data which is predetermine and extremely unlikely to ever change? Can one lock Core Data down so that its data can't change, thereby relinquishing my responsibility as the developer to handle the editing and saving of the managed object context? How do I go about giving Core Data my predetermined data, and in a format I know that it can work with? Thanks a bunch guys.

  • Selenium: How to click buttons that use onclick window.location?

    - by Andrew
    I have a button (outside of a form) that redirects to another page using the onclick attribute that calls window.location to redirect the user to another page. This time I can't change the HTML. I am using Safari 4 for testing. How can I click a button that uses the onclick attribute and window.location to redirect using Safari 4 and Selenium RC PHPUnit Extension? Here's my HTML: <input type="button" onclick="window.location='/registrations/new'" value="Start a new registration" id="create">

  • How does Core Data determine if an NSObjects data can be dropped?

    - by Kevin
    In the app I am working on now I was storing about 500 images in Core Data. I have since pulled those images out and store them in the file system now, but in the process I found that the app would crash on the device if I had an array of 500 objects with image data in them. An array with 500 object ids with the image data in those objects worked fine. The 500 objects without the image data also worked fine. I found that I got the best performance with both an array of object ids and image data stored on the filesystem instead of in core data. The conclusion I came to was that if I had an object in an array that told Core Data I was "using" that object and Core Data would hold on to the data. Is this correct?

  • Can we use union of two sqlite databases with same tables for Core Data?

    - by Tofrizer
    Hi All, I have an iPhone Core Data app with a pre-populated sqlite "baseline" database. Can I add a second smaller sqlite database with the same tables as my pre-populated "baseline" database but with additional / complementary data such that Core Data will happily union the data from both databases and, ultimately, present to me as if it was all a single data source? Idea that I had is: 1) the "baseline" database never changes. 2) I can download the smaller "complementary" sqlite database for additional data as and when I need to (I'm assuming downloading sqlite database is allowed, please comment if otherwise). 3) Core Data is then able to union data from 1 & 2. I can then reference this unified data by calling my defined Core Data managed object model. Hope this makes sense. Thanks in advance.
