• What's the most efficient way to setup a multi-lingual website

  - by Jasper De Bruijn

  Hi, I'm developing a website that will be available in different languages. It is a LAMP (Linux, Apache, MySQL, PHP) setup, and it makes use of Smarty, mostly for the template engine. The way we currently translate is by a self-written smarty plugin, which will recognize certain tags in the HTML files, and will find the corresponding tag in an earlier defined language file. The HTML could look as follows: <p>Hi, welcome to $#gamedesc;!</p> And the language file could look like this: gamedesc:Poing 2009$; welcome:this is another tag$; Which would then output <p>Hi, welcome to Poing 2009!</p> This system is very basic, but it is pretty hard to control, if I f.e. would like to keep track of what has been translated so far, or give certain users the rights to translate only certain tags. I've been looking at some alternative ways to approach this, by either replacing the text-file with XML files which could store some extra meta-data, or by perhaps storing all the texts in the database, and retrieving it there. My question is, what would be the best way to make this system both maintainable and perform well with high user-traffic? Are there perhaps any (lightweight) plugins I could take a look at?

• Animate a GIF using Core Animation layers?

  - by Cliff

  I'm trying to animate a GIF and I hit a roadblock. I have an example of what I'm trying to do that uses the individual frames of the GIF and setting the animationImages property of a UIView. However in my project, the thing I want to animate is drawn using Layers. I'm looking for a quick and easy way to animate the frames without introducing too much complexity. Is there any animationImages equivalent with Layers? Does anybody have any ideas?

• delete multi-line block of text with internal flag in povray file

  - by Sibo Lin

  I have a pov-ray file, which defines a lot of cylinders and spheres. Sometimes these shapes are defined to have "color@", which makes the povray unrenderable. One solution I've found is to delete the offending cylinders and spheres. So a file that contains this text cylinder { < -0.17623, 0.24511, -0.27947>, < -0.15220, 0.22658, -0.26472>, 0.00716 texture { colorO } } sphere { < -0.00950, 0.00357, 0.00227>, 0.00716 texture { color@ } } cylinder { < -0.00950, 0.00357, 0.00227>, < 0.00327, 0.00169, 0.00108>, 0.00716 texture { color@ } } sphere { < 0.15373, 0.00601, 0.18223>, 0.00716 texture { colorO } } would turn into this text cylinder { < -0.17623, 0.24511, -0.27947>, < -0.15220, 0.22658, -0.26472>, 0.00716 texture { colorO } } sphere { < 0.15373, 0.00601, 0.18223>, 0.00716 texture { colorO } } Is there some way to do this replacement with a shell script? Preferably in tcsh. Thanks!

• Keeping iPhone application in sync with GWT application.

  - by Reflog

  Hi, I'm working on an iPhone application that should work in offline and online modes. In it's online mode it's supposed to feed all the information the user enters to a webservice backed by GWT/GAE. In it's offline mode it's supposed to store the information locally, and when connection is available sync it up to the web service. Currently my plan is as follows: Provide a connection between an app and a webservice using Protobuffers for efficient over-the-wire communication Work with local DB using Core Data Poll the network status, and when available sync the database and keep some sort of local-db-to-remote-db key synchronization. The question is - am I in the right direction? Are the standard patterns for implementing this? Maybe someone can point me to an open-source application that works in a similar fashion? I am really new to iPhone coding, and would be very glad to hear any suggestions. Thanks

• multi column sorting of datagrid view:

  - by Bi

  I have a datagridview in a windows form with 3 columns: Serial number, Name and Date-Time. The Name column will always have either of the two values: "name1" or "name2". I need to sort these columns such that the grid displays all the rows with name values in a specific order (first display all the "name1" rows and then all the "name2" rows). Within the "name1" rows, I want the rows to be sorted by the Date-Time. Please note programmatically, all the 3 columns are strings. For example, if I have the rows: 01 |Name1 | 2010-05-05 10:00 PM 02 |Name2 | 2010-05-02 08:00 AM 03 |Name2 | 2010-05-01 08:00 AM 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM needs to be sorted as 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM 01 |Name1 | 2010-05-05 10:00 PM 03 |Name2 | 2010-05-01 08:00 AM 02 |Name2 | 2010-05-02 08:00 AM I am not sure how to go about using the below: myGrid.Sort(.....,ListSortDirection.Ascending)

• NSFetchedResultsController not processing certain section driven moves

  - by JK

  I utilize a NSFetchedResultsController (frc) with a Core Data store. I implement all the frc delegate methods. The table is sporadically updated by background threads. All the inserts, deletes and updates work fine, with the exception that updates to the frc's index key for rows toward to the bottom of the table (50 rows), do not result in a section move. e.g. if "name" is the index key and the name "Victor" is changed to "Alex", the victor row now shows the name Alex, but is not moved to the top of the table alongside all other names starting with A. As I noted, this is only for rows towards the bottom of the table. If a row like "Andy" is changed to "Ben", the move is indeed processed correctly by the frc. Any suggestions to fix this would be appreciated. I do not use a frc cache. Thanks

• G++ Multi-platform memory leak detection tool

  - by indyK1ng

  Does anyone know where I can find a memory memory leak detection tool for C++ which can be either run in a command line or as an Eclipse plug-in in Windows and Linux. I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great. This question is similar to other questions (such as http://stackoverflow.com/questions/283726/memory-leak-detection-under-windows-for-gnu-c-c ) however I feel it is different because those ask for windows specific solutions or have solutions which I would rather avoid. I feel I am looking for something a bit more specific here. Suggestions don't have to fulfill all requirements, but as many as possible would be nice. Thanks. EDIT: Since this has come up, by "overwrite" I mean anything which requires me to #include a library or which otherwise changes how C++ compiles my code, if it does this at run time so that running the code in a different environment won't affect anything that would be great. Also, unfortunately, I don't have a Mac, so any suggestions for that are unhelpful, but thank you for trying. My desktop runs Windows (I have Linux installed but my dual monitors don't work with it) and I'd rather not run Linux in a VM, although that is certainly an option. My laptop runs Linux, so I can use that tool on there, although I would definitely prefer sticking to my desktop as the screen space is excellent for keeping all of the design documentation and requirements in view without having to move too much around on the desktop. NOTE: While I may try answers, I won't mark one as accepted until I have tried the suggestion and it is satisfactory. EDIT2: I'm not worried about the cross-platform compatibility of my code, it's a command line application using just the C++ libraries.

• Are CMAttitude and CATransform3D related by rotational matrices?

  - by Alex Stone

  I'm looking at the core motion class CMAttitude, it can express the device's orientation as a 3x3 rotational matrix. At the same time I've taken a look at the CATransform3D, which encapsulates the view's attitude, as well as scaling. The CATransform3D is a 4x4 matrix. I've seen that the OpenGL rotational matrix is 4x4 and is simply 0001 padded in the 4th row and column. I'm wandering if the CMAttitude's rotational matrix is related to CATransform's matrix? Can I use the device's rotation in space obtained via a rotational matrix to transform a UIView using CATransform3D? My intention is to let the user move the phone and apply the same transform to a UIView on the screen. Bonus question: if they are related, how do I transform a CMAttitude's rotational matrix to CATransform3D?

• Multi-line regex support in Vim

  - by Daniel

  I notice the standard regex syntax for matching across multiple lines is to use /s, like so: This is\nsome text /This.*text/s This works in Perl for instance but doesn't seem to be supported in Vim. Instead, I have to be much more specific: /This[^\r\n]*[\r\n]*text/ I can't find any reason for why this should be, so I'm thinking I probably just missed the relevant bits in the vim help. Can anyone confirm this behaviour one way or the other?

• c# multi threaded file processing

  - by user177883

  There is a folder that contains 1000 of small text files. I aim to parse and process all of them while more files are being populated in to the folder. My intention is to multithread this operation as the single threaded prototype took 6 minutes to process 1000 files. I like to have reader and writer thread(s) as following : while the reader thread(s) are reading the files, I d like to have writer thread(s) to process them. Once the reader is started reading a file, I d like to mark it as being processed, such as by renaming it, once it s read, rename it to completed. How to approach such multithreaded application ? Is it better to use a distributed hash table or a queue? Which data structure to use that would avoid locks? Would you have a better approach to this scheme that you like to share?

• Why doesn't the undo/redo panel appear when I start a shake gesture in iPhone Simulator?

  - by dontWatchMyProfile

  I've created an NSUndoManager for the Managed Object Context of Core Data, like this: NSUndoManager *undoManager = [[NSUndoManager alloc] init]; [undoManager setLevelsOfUndo:10]; [managedObjectContext setUndoManager:undoManager]; [undoManager release]; In the app delegate where the didFinishLaunching method is called, I did this: application.applicationSupportsShakeToEdit = YES; For some reason, I never get that undo/redo panel when I make a shake gesture in iPhone Simulator (from the menu). Must I enable undo/redo somewhere else, maybe in the Info.plist file?

• Multi threading in WCF RIA Services

  - by synergetic

  I use WCF RIA Services to update customer database. In domain service: public void UpdateCustomer(Customer customer) { this.ObjectContext.Customers.AttachAsModified(customer); syncCustomer(customer); } After update, a database trigger launches and depending on the columns updated it may insert a new record in CustomerChange table. syncCustomer(customer) method is executed to check for a new record in the CustomerChange table and if found it will create a text file which contains customer information and forwards that file to external system for import. Now this synchronization may take a time so I wanted to execute it in different thread. So: private void syncCustomer(Customer customer) { this.ObjectContext.SaveChanges(); new Thread(() => syncCustomerInfo(customer.CustomerID)) { IsBackground = true }.Start(); } private void syncCustomerInfo(int customerID) { //Thread.Sleep(2000); //does real job here ... ... } The problem is in most cases syncCustomerInfo method cannot find any new CustomerChange record even if it was definitely there. If I force thread sleep then it finds a new record. I also looked Entity Framework events but the only event provided by object context is SavingChanges which occur before changes are saved. Please suggest me what else to try.

• coco2d tab view for multi player

  - by godzilla

  I am currently developing a card game for the iphone using cocas2d. I am currently in need of a tab view with each tab representing a player and his / her set of cards. Currently i have a single view representing just one player. It seems as though cocas2s is not really built do have multiple views, to do this and it would require some serious amount of hacking around with the code. What would be the most efficient way to accomplish this?

• TeamCity Multi-Part Build - How to checkout the code just once

  - by Jeff D

  I am trying to create 1 package with multiple build configurations. The first will checkout the code, build it (Solution File configuration), and run nunit tests. If that succeeds, another will then build in release mode. If that succeeds, a final script witll package up the output, and mark it as an artifact. The problem I'm having is that I don't know how to tell TeamCity not to create new directories for each step, and as a result, the steps are failing. Is there a setting for this? It seems like the dependencies tab would be an appropriate place to look, but I don't seem to understand the instructions, and my tinkering so far has been fruitless.

• data not reloading into tableview from core data on minor update

  - by Martin KS

  I've got a basic photo album application, on the first view a list of albums is displayed with a subtitle showing how many images are in each album. I've got everything working to add albums, and add images to albums. The problem is that the image count lines are accurate whenever the app loads, but I can't get them to update during execution. The following viewdidload correctly populates all lines of the tableview when the app loads: - (void)viewDidLoad { [super viewDidLoad]; // Set the title. self.title = @"Photo albums"; // Configure the add and edit buttons. self.navigationItem.leftBarButtonItem = self.editButtonItem; addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAlbum)]; addButton.enabled = YES; self.navigationItem.rightBarButtonItem = addButton; /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by name. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; } But when I run similar code inside viewdidappear, nothing happens: { /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by creation date, most recent first. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [self.tableView reloadData]; [mutableFetchResults release]; [request release]; } Apologies if I've missed the answer to this question elsewhere, but what am I missing?

• If you are a hard core .NET programmer, would you invest in learning Java

  - by GarbageGuy

  Learning just another language is not much work. However, getting familiar with all the supporting libraries is veeeery expensive and actually you cannot go too far without that. Would you consider a worthy career investment to learn java once you already are an accepted professional of .NET or you would rather invest the same amount of energy to get deeper in the things you already know?

• iPhone - finding items in current entity that share related item

  - by Pedro

  G'day Folks My core data driven app has an Events entity, essentially a list of times & venues, with a related Acts entity, the names & bios of the acts appearing at those events. I have a table view that shows the event time & venue (as a table section with 1 row), the act name & act bio that works nicely. If that act is appearing at more than one event I'd like to include another table section that lists those events. I think could get that with event.act.events except that it would include the event I'm currently displaying. Can anyone suggest how to get the data I want & exclude the current record? Cheers & TIA, Pedro :) PS... I have not quite 18 hours until the promised time for a prototype of my app to be available for some testers to download.
