  • android compile error: could not reserve enough space for object heap

    - by moonlightcheese
    I'm getting this error during compilation: Error occurred during initialization of VM Could not create the Java virtual machine. Could not reserve enough space for object heap What's worse, the error occurs intermittently. Sometimes it happens, sometimes it doesn't. It seems to be dependent on the amount of code in the application. If I get rid of some variables or drop some imported libraries, it will compile. Then when I add more to it, I get the error again. I've included the following sources into the application in the [project_root]/src/ directory: org.apache.httpclient (I've stripped all references to log4j from the sources, so don't need it) org.apache.codec (as a dependency) org.apache.httpcore (dependency of httpclient) and my own activity code consisting of nothing more than an instance of HttpClient. I know this has something to do with the amount of memory necessary during compile time or some compiler options, and I'm not really stressing my system while i'm coding. I've got 2GB of memory on this Core Duo laptop and windows reports only 860MB page file usage (haven't used any other memory tools. I should have plenty of memory and processing power for this... and I'm only compiling some common http libs... total of 406 source files. What gives? Android API Level: 5 Android SDK rel 5 JDK version: 1.6.0_12

  • Finding source of over release

    - by Benedict Lowndes
    Hi, I'm consistently seeing the same message sent in as a crash report from users of an app. It's clear that an object is being over-released but I'm unable to replicate it and I'm looking for tips on tracing the source of it. The relevant section from the crash report shows this: Application Specific Information: objc_msgSend() selector name: release Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x90892edb objc_msgSend + 27 1 com.apple.CoreFoundation 0x95ec5a40 __CFBasicHashStandardCallback + 384 2 com.apple.CoreFoundation 0x95ec564e __CFBasicHashDrain + 478 3 com.apple.CoreFoundation 0x95ead6f1 _CFRelease + 353 4 com.apple.CoreFoundation 0x95eda0ed _CFAutoreleasePoolPop + 253 5 com.apple.Foundation 0x97ecedd6 NSPopAutoreleasePool + 76 6 com.apple.Foundation 0x97ececfe -[NSAutoreleasePool drain] + 130 7 com.apple.AppKit 0x9211255f -[NSApplication run] + 1013 8 com.apple.AppKit 0x9210a535 NSApplicationMain + 574 9 TheApp 0x000020a6 start + 54 I've used zombies and leaks, but haven't seen anything there. I've gone through the code and can't see it. What's the next step? Are there any hints I can discern from this information as to the source of it? Does the fact that this nearly exact same crash report is coming in repeatedly mean that it's the same object that's being over released, or because this is referring to the autorelease pool mean it could be any object? Does the reference to _CFRelease mean it's a Core Foundation object that's being over released?

  • Django-modpython project in a directory

    - by Ankit Jaiswal
    Hi All, I am deploying a Django project on apache server with mod_python in linux. I have created a directory structure like: /var/www/html/django/demoInstall where demoInstall is my project. In the httpd.conf I have put the following code. <Location "/django/demoInstall"> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE demoInstall.settings PythonOption django.root django/demoInstall PythonDebug On PythonPath "['/var/www/html/django'] + sys.path" </Location> It is getting me the django environment but the issue is that the urls mentioned in urls.py are not working correctly. In my url file I have mentioned the url like: (r'^$', views.index), Now, in the browser I am putting the url like : http://domainname/django/demoInstall/ and I am expecting the views.index to be invoked. But I guess it is expecting the url to be only: http://domainname/ . When I change the url mapping to: (r'^django/demoInstall$', views.index), it works fine. Please suggest as I do not want to change all the mappings in url config file. Thanks in advance.

  • py2app, pyObjc & macports compilation errors

    - by Neewok
    Hi, I'm currently writing a small python app that embeds cherrypy and django using py2app. It worked well until I tried to include pyobjc in my project, since my app needed a small GUI (which consists of a small icon in the top menu bar + a drop down menu). I can run my python script without any problem (I'm using python 2.6 with macports), but I can't launch the application bundle generated by py2app. A dialog box appears with the following message: ImportError: dlopen(/Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so, 2): no suitable image found. Did find: /Users/denis/tlon/standalone/mac/dist/django_cherry.app/Contents/Resources/lib/python2.6/lib-dynload/CoreFoundation/_inlines.so: mach-o, but wrong architecture I did a quick : sudo port -u install py26-pyobjc +universal but for some reason macports tries to build openssl, with which compilation fails each time. It seems the problem is related to zLib - this is what appears in the logs : :info:build ld: warning: in /opt/local/lib/libz.dylib, file is not of required architecture ...And here is the output of file /opt/local/lib/libz.dylib : /opt/local/lib/libz.dylib: Mach-O universal binary with 2 architectures /opt/local/lib/libz.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 /opt/local/lib/libz.dylib (for architecture i386): Mach-O dynamically linked shared library i386 Nothing looks wrong to me. I'm a bit stuck here. I don't even understand what openssl has to do with pyObjc, but it looks like I can't go anywhere if I don't manage to compile it. Macports really suck sometimes :/ EDIT I manage to fix Macports issue, but not py2app one. If I get it right, py2app try to create a 32-bits app, while Core Foundation files on Snow Leopard are for 64 bits architectures. Damn. Either I build this on Leopard, either I have to find a way to create a 64bit app with py2app, but then Snow Leopard only.

  • Git-svn refuses to create branch on svn repository error: "not in the same repository"

    - by Danny
    I am attempting to create a svn branch using git-svn. The repository was created with --stdlayout. Unfortunately it generates an error stating the "Source and dest appear not to be in the same repository". The error appears to be the result of it not including the username in the source url. $ git svn branch foo-as-bar -m "Attempt to make Foo into Bar." Copying svn+ssh://my.foo.company/r/sandbox/foo/trunk at r1173 to svn+ssh://[email protected]/r/sandbox/foo/branches/foo-as-bar... Trying to use an unsupported feature: Source and dest appear not to be in the same repository (src: 'svn+ssh://my.foo.company/r/sandbox/foo/trunk'; dst: 'svn+ssh://[email protected]/r/sandbox/foo/branches/foo-as-bar') at /home/me/.install/git/libexec/git-core/git-svn line 610 I intially thought this was simply a configuration issue, examination of .git/config doesn't suggest anything incorrect. [svn-remote "svn"] url = svn+ssh://[email protected]/r fetch = sandbox/foo/trunk:refs/remotes/trunk branches = sandbox/foo/branches/*:refs/remotes/* tags = sandbox/foo/tags/*:refs/remotes/tags/* I am using git version 1.6.3.3. Can anyone shed any light on why this might be occuring, and how best to address it?

  • How to do fixed price quote for design sessions?

    - by Shaul
    Normally when I do a system for a customer, I do design sessions on an hourly rate and then come out with a fixed price quotation for the full system development. Now this customer has thrown me a curveball: he doesn't want an hourly rate for design, either - he wants me to quote a fixed price to do all the design, too! Not that he's trying to cheap out, but he doesn't want to be in a situation where the longer design stretches out, the more he has to pay - and I can understand that. For the business layer it was actually not too difficult to work with this, because from his original functional spec I got a good idea of what the core business objects were, and in our design agreement I defined several objects which would be covered by a fixed design price; if any new non-trivial objects were discovered, they would be considered variances, and those would be billed on an hourly rate. So far so good. But when it comes to the UI, things start getting a lot more woolly. How many screens will there be? Don't know yet. What's going to be on each screen? Don't know yet. All we know is that it's a "dashboard" type of system, and there will be a lot of visual reporting involved e.g. gauges, graphs, etc. So maybe make it fixed price per screen design? Not a great definition; he might say that everything is going to be on one screen. Maybe a price per "visual report" design, including ability to slice & dice? Again not so easy - it might be that the entire system is just one report, and all the intelligence is going to go into how to present that segmentation. Anyone have any ideas how to do a fixed price quotation for a UI design like this?

  • Nav Controller, UITableViewController, UITextField to become firstResponder?

    - by Daniel Granger
    I have a core data application which uses a navigation controller to drill down to a detail view and then if you edit one of the rows of data in the detail view you get taken to an Edit View for the that single line, like in Apples CoreDataBooks example! The edit view is a UITableviewController which creates its table with a single section single row and a UITextfield in the cell, programatically. What I want to happen is when you select a row to edit and the edit view is pushed onto the nav stack and the edit view is animated moving across the screen, I want the textfield to be selected as firstResponder so that the keyboard is already showing as the view moves across the screen to take position. Like in the Contacts app or in the CoreDataBooks App. I currently have the following code in my app which causes the view to load and then you see the keyboard appear (which isn't what I want, I want the keyboard to already be there) - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [theTextField becomeFirstResponder]; } You can't put this in -viewWillAppear as the textfield hasn't been created yet so theTextField is nil. In the CoreDataBooks App where they achieve what i want they load there tableview from a nib so they use the same code but in -viewWillAppear as the textfield has already been created! Is there anyway of getting around this without creating a nib, I want to keep the implementation programatic to enable greater flexibility. Many Thanks

  • Using jQuery, setting Draggable on an element prevents blur from firing when you click the draggable

    - by Danno
    Using jQuery, when you set a blur event on a text box and set another element as draggable, when you click the draggable element, the blur event does not fire in FireFox. IE is a little better, you get the blur event but you don't get the click event on the draggable element. If you don't specify the cancel: "" in the draggable constructor, you will get the blur event to fire, but then the element you want to drag is not draggable. jQuery v1.3.2 jQuery UI v1.7.2 The console.log lines are for FireFox's FireBug plugin. <HTML> <HEAD> <TITLE>Blur/Click Workbench</TITLE> <script src="js/jquery.js" type="text/javascript" ></script> <script src="js/ui/ui.core.js" type="text/javascript"></script> <script src="js/ui/ui.draggable.js" type="text/javascript"></script> <script type="text/javascript"> function blurring() { console.log('1 - blurring - ' + $( this ).attr('id')); } function clicking() { console.log('2 - clicking - ' + $( this ).attr('id')); } $(document).ready(function() { $( ".draggableTool" ).draggable( { cancel: "" } ); $( '.property' ).blur( blurring ); $( '#labelContainer' ).click( clicking ); }); </script> </HEAD> <BODY> <input type='text' class='property' id='tb1' /> <br /> <input type='text' class='property' id='tb2' /> <br /> <label class='draggableTool' id='labelContainer' style='height:20px;position:absolute;'> <textarea id='taLabel' style='height:100%;background-color:white;border:1px solid grey;'>Label</textarea> </label> </BODY> </HTML>

  • How are you taking advantage of Multicore?

    - by tgamblin
    As someone in the world of HPC who came from the world of enterprise web development, I'm always curious to see how developers back in the "real world" are taking advantage of parallel computing. This is much more relevant now that all chips are going multicore, and it'll be even more relevant when there are thousands of cores on a chip instead of just a few. My questions are: How does this affect your software roadmap? I'm particularly interested in real stories about how multicore is affecting different software domains, so specify what kind of development you do in your answer (e.g. server side, client-side apps, scientific computing, etc). What are you doing with your existing code to take advantage of multicore machines, and what challenges have you faced? Are you using OpenMP, Erlang, Haskell, CUDA, TBB, UPC or something else? What do you plan to do as concurrency levels continue to increase, and how will you deal with hundreds or thousands of cores? If your domain doesn't easily benefit from parallel computation, then explaining why is interesting, too. Finally, I've framed this as a multicore question, but feel free to talk about other types of parallel computing. If you're porting part of your app to use MapReduce, or if MPI on large clusters is the paradigm for you, then definitely mention that, too. Update: If you do answer #5, mention whether you think things will change if there get to be more cores (100, 1000, etc) than you can feed with available memory bandwidth (seeing as how bandwidth is getting smaller and smaller per core). Can you still use the remaining cores for your application?

  • Forcing CLLocationManager updates - does it help or hurt?

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

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?

  • Django Admin: not seeing any app (permission problem?)

    - by Facundo
    I have a site with Django running some custom apps. I was not using the Django ORM, just the view and templates but now I need to store some info so I created some models in one app and enabled the Admin. The problem is when I log in the Admin it just says "You don't have permission to edit anything", not even the Auth app shows in the page. I'm using the same user created with syncdb as a superuser. In the same server I have another site that is using the Admin just fine. Using Django 1.1.0 with Apache/2.2.10 mod_python/3.3.1 Python/2.5.2, with psql (PostgreSQL) 8.1.11 all in Gentoo Linux 2.6.23 Any ideas where I can find a solution? Thanks a lot. UPDATE: It works from the development server. I bet this has something to do with some filesystem permission but I just can't find it. UPDATE2: vhost configuration file: <Location /> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE gpx.settings PythonDebug On PythonPath "['/var/django'] + sys.path" </Location> UPDATE 3: more info /var/django/gpx/init.py exists and is empty I run python manage.py from /var/django/gpx directory The site is GPX, one of the apps is contable and lives in /var/django/gpx/contable the user apache is webdev group and all these directories and files belong to that group and have rw permission UPDATE 4: confirmed that the settings file is the same for apache and runserver (renamed it and both broke) UPDATE 5: /var/django/gpx/contable/init.py exists This is the relevan part of urls.py: urlpatterns = patterns('', (r'^admin/', include(admin.site.urls)), ) urlpatterns += patterns('gpx', (r'^$', 'menues.views.index'), (r'^adm/$', 'menues.views.admIndex'),

  • Using the MVVM Light Toolkit to make Blendable applications

    - by Dave
    A while ago, I posted a question regarding switching between a Blend-authored GUI and a Visual Studio-authored one. I got it to work okay by adding my Blend project to my VS2008 project and then changing the Startup Application and recompiling. This would result in two applications that had completely different GUIs, yet used the exact same ViewModel and Model code. I was pretty happy with that. Now that I've learned about the Laurent Bugnion's MVVM Light Toolkit, I would really like to leverage his efforts to make this process of supporting multiple GUIs for the same backend code possible. The question is, does the toolkit facilate this, or am I stuck doing it my previous way? I've watched his video from MIX10 and have read some of the articles about it online. However, I've yet to see something that indicates that there is a clean way to allow a user to either dynamically switch GUIs on the fly by loading a different DLL. There are MVVM templates for VS2008 and Blend 3, but am I supposed to create both types of projects for my application and then reference specific files from my VS2008 solution? UPDATE I re-read some information on Laurent's site, and seemed to have forgotten that the whole point of the template was to allow the same solution to be opened in VS2008 and Blend. So anyhow, with this new perspective it looks like the templates are actually intended to use a single GUI, most likely designed entirely in Blend (with the convenience of debugging through VS2008), and then be able to use two different ViewModels -- one for design-time, and one for runtime. So it seems to me like the answer to my question is that I want to use a combination of my previous solution, along with the MVVM Light Toolkit. The former will allow me to make multiple, distinct GUIs around my core code, while the latter will make designing fancy GUIs in Blend easier with the usage of a design-time ViewModel. Can anyone comment on this?

  • Writing to a log4net FileAppender with multiple threads performance problems

    - by Wayne
    TickZoom is a very high performance app which uses it's own parallelization library and multiple O/S threads for smooth utilization of multi-core computers. The app hits a bottleneck where users need to write information to a LogAppender from separate O/S threads. The FileAppender uses the MinimalLock feature so that each thread can lock and write to the file and then release it for the next thread to write. If MinimalLock gets disabled, log4net reports errors about the file being already locked by another process (thread). A better way for log4net to do this would be to have a single thread that takes care of writing to the FileAppender and any other threads simply add their messages to a queue. In that way, MinimalLock could be disabled to greatly improve performance of logging. Additionally, the application does a lot of CPU intensive work so it will also improve performance to use a separate thread for writing to the file so the CPU never waits on the I/O to complete. So the question is, does log4net already offer this feature? If so, how do you do enable threaded writing to a file? Is there another, more advanced appender, perhaps? If not, then since log4net is already wrapped in the platform, that makes it possible to implement a separate thread and queue for this purpose in the TickZoom code. Sincerely, Wayne

  • Extending spring based app

    - by pitr
    I have a spring-based Web Service. I now want to build a sort of plugin for it that extends it with beans. What I have now in web.xml is: <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/*-configuration.xml</param-value> </context-param> My core app has main-configuration.xml which declares its beans. My plugin app has plugin-configuration.xml which declares additional beans. Now when I deploy, my build deploys plugin.jar into /WEB-INF/lib/ and copies plugin-configuration.xml into /WEB-INF/classes/ all under main.war. This is all fine (although I think there could be a better solution), but when I develop the plugin, I don't want to have two projects in Eclipse with dependencies. I wish to have main.jar that I include as a library. However, web.xml from main.jar isn't automatically discovered. How can I do this? Bean injection? Bean discovery of some sort? Something else? Note: I expect to have multiple different plugins in production, but development of each of them will be against pure main.jar Thank you.

  • SQL Server 2005 standard filegroups / files for performance on SAN

    - by Blootac
    Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

  • Caching a column in a polymorphic relationship

    - by Brendon Muir
    I have content management system application that uses a polymorphic tree table as the core of its arrangement. I've come into a problem where once the tree grows quite large, and because we have quite a few different modules (about 25), just doing :include = :instance doesn't cut the mustard. Instance is the name of our polymorphic relationship. The funny part is that in most cases when I want a large list of these items, all I really want is their name from the associated table (for the purposes of an index bar for example), all the rest is in the central table. So I thought that I should probably implement some sort of column cache for the name in the central table. (Like a counter cache that rails already does). I was just wondering if a plugin exists to manage this already? If not, I was just going to add a 'name' column to the central table and because all the polymorphic models inherit off a superclass, just add a callback that pushes the name across to the central table whenever the item is created or updated. I'd then just do a big migration to populate it in the first place? Any flaws to that design? I suppose to be more flexible the column could be some kind of serialised cache where I could store other things later on if need be? Gah! :D

  • Big sinatra problems

    - by Joel M.
    Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?

  • Delete NSManageObject at the event tableView:commitEditingStyle:forRowAtIndexPath:

    - by David.Chu.ca
    I got exception when I tried to delete one NSManageObject at the event of tableView:commitEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting? I found that in the Apple's Core Data Tutorial for iPhone with events example, there is on NSArray to hold event entity objects. I am not sure if that's necessory to use NSArray to hold my local entity objects and then use it for deleting?
