  • High load without explanation

    - by Sebastian
    I have a very high load on my machine and don't know what is responsible or how to find out. On the machine runs a jboss appserver and mysql. Here is a top from the user at peak time: top - 16:23:01 up 101 days, 6:50, 1 user, load average: 23.42, 21.53, 24.73 Tasks: 9 total, 1 running, 8 sleeping, 0 stopped, 0 zombie Cpu(s): 17.2%us, 1.6%sy, 0.0%ni, 80.4%id, 0.1%wa, 0.1%hi, 0.7%si, 0.0%st Mem: 16440784k total, 16263720k used, 177064k free, 151916k buffers Swap: 16780872k total, 30428k used, 16750444k free, 8963648k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 27344 b 40 0 16.0g 6.5g 14m S 169 41.7 1184:09 java 6047 b 40 0 11484 1232 1228 S 0 0.0 0:00.01 mysqld_safe 6192 b 40 0 604m 182m 4696 S 0 1.1 93:30.40 mysqld 7948 b 40 0 84036 1968 1176 S 0 0.0 0:00.07 sshd 7949 b 40 0 14004 2900 1608 S 0 0.0 0:00.03 bash 7975 b 40 0 8604 1044 840 S 0 0.0 0:00.44 top The CPU usage of the java process is normal.

  • Suggestions for hosted file sharing services

    - by Jon
    Before I pose my question, I will give some insight as per my scenario: I work for a small business (cost is an important factor) Our bandwidth is limited and would not support an in-house FTP server We need to share files (mostly pdf, inDesign, Illustrator documents) to our clients, and as we expand, we are finding that our current locally-hosted FTP solution is too slow and is becoming a detriment to our sales team. What we need is a remotely hosted solution to share files with our clients, specifically with the following features: Greater than 100gb of secure storage The Ability to distribute unique log in credentials to clients, granting access to a personalized directory or folder, while limiting access to other files on the server. A relatively simple web-based UI for clients with limited computer knowledge We have considered a dedicated remote server, and web-based services (box.net, yousendit.com, onehub.com, filesanywhere.com) but I am unsure as per the direction we should be taking - have I left another solution out? What would you suggest? Thanks in advance.

  • Notepad++ FTP best solution

    - by yoda
    Hi, I use Notepad++ for more than 2 years now, and there's only 1 thing that it needs for me to be perfect: a actually-working-ftp-plugin. It has an ftp plugin, written by someone that meanwhile left the project (by meanwhile I mean a long time ago), and since then nobody had courage to improve it. The problem is that it does't handle connections very well. Sometimes it lost connection with the server and literally "blocks", others don't save the files properly, other only load half of the ftp files, etc etc .. My question is: Is there a way to use ftp and notepad++ (without using its build-in ftp or a ftp client like filezilla)? I've tried using NetDrive, but it gets stuck sometimes (makes the editor crash), and everytime the temporary file is refreshed by windows / NetDrive, it will load the new file without asking and skip the pointer to the end of the file (very very very annoying). In case you know how to make the built-in notepad++ ftp plugin work at 100%, I'd be much more happy! I'd like to have some feedback from you guys :) (I'm using Windows Vista) Thanks in advance!

  • Django: way to test what class a generic relation content_object is?

    - by bitbutter
    In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

  • How can I customize the title bar on JFrame?

    - by Jonas
    I would like to have a customized title bar in my Java Swing desktop application. What is the best way to do that? I can use a "Swing-title bar" by using the following code in the constructor for my JFrame: this.setUndecorated(true); this.getRootPane().setWindowDecorationStyle(JRootPane.FRAME); But how do I customize it? Is there any UI delegates that I can override or do I have to implement my own title bar from scratch? I want something like Lawson Smart Office: Or like Trend Micro Internet Security:

  • Casting a container of shared_ptr

    - by Jamie Cook
    Hi all, I have a method void foo(list<shared_ptr<Base>>& myList); Which I'm trying to call with a two different types of lists, one of DerivedClass1 and one of DerivedClass2 list<shared_ptr<DerivedClass1>> myList1; foo(myList1); list<shared_ptr<DerivedClass2>> myList2; foo(myList2); However this obviously generates a compiler error error: a reference of type "std::list<boost::shared_ptr<Base>, std::allocator<boost::shared_ptr<Base>>> &" (not const-qualified) cannot be initialized with a value of type "std::list<boost::shared_ptr<DerivedClass1>, std::allocator<boost::shared_ptr<DerivedClass1>>>" Is there any easy way to cast a container of shared_ptr? Of alternate containers that can accomplish this?

  • ASP.NET: How to "reset" validation after calling Page_ClientValidate

    - by Josh Young
    I have an ASP.NET page with a jQuery dialog that is displayed to change some data. I am setting up the jQuery dialog so that when the user clicks the OK button it calls ASP.NET's Page_ClientValidate('validationGroup') via javascript, finds all the invalid controls and changes their CSS class. So here's the scenario: the user opens the dialog, keys in some invalid data, clicks OK (receiving the validation messages), and then clicks Cancel. Now the dialog is closed, but the validation messages are still there, so that when they open the dialog again, the data goes back to the way it was initially, but the form is still in the invalid state (the validation messages are still displaying). What I need is a "reset" function of sorts to call after calling Page_ClientValidate('validationGroup'). Does this exist?

  • Transforming a TXT file in a list, getting wrong

    - by Mike
    I have a txt plain file that has a list of numbers. One number per line, like: 978-972-722-649-8 978-972-722-646-7 978-972-722-627-6 978-972-722-625-2 978-972-722-594-1 etc. This list is on a file called file.txt, was created and saved on TextEdit using Western (ISO Latin 1) encoding. Now I am trying to use Applescript to read this file and transform it on a list. I have this script set myDirectory to path to desktop folder as string set myFile to myDirectory & "file.txt" try set open_file to ¬ open for access file myFile without write permission set myList to read open_file using delimiter return close access open_file on error try close access file open_file end try end try after running this script, myList contains just ONE item and this item is "97" (I suppose that is the first two numbers of the first entry). What is going on? Thanks.

  • Fail to save a managed object to core-data after its properties were updated.

    - by Tzur Gazit
    I have to trouble to create the object, but updating it fails. Here is the creation code: // Save data from pList to core data fro the first time - (void) saveToCoreData:(NSDictionary *)plistDictionary { // Create system parameter entity SystemParameters *systemParametersEntity = (SystemParameters *)[NSEntityDescription insertNewObjectForEntityForName:@"SystemParameters" inManagedObjectContext:mManagedObjectContext]; //// // GPS SIMULATOR //// NSDictionary *GpsSimulator = [plistDictionary valueForKey:@"GpsSimulator"]; [systemParametersEntity setMGpsSimulatorEnabled:[[GpsSimulator objectForKey:@"Enabled"] boolValue]]; [systemParametersEntity setMGpsSimulatorFileName:[GpsSimulator valueForKey:@"FileName"]]; [systemParametersEntity setMGpsSimulatorPlaybackSpeed:[[GpsSimulator objectForKey:@"PlaybackSpeed"] intValue]]; [self saveAction]; } During execution the cached copy is changed and then it is saved (or trying) to the database. Here is the code to save the changed copy: // Save data from pList to core data fro the first time - (void) saveSystemParametersToCoreData:(SystemParameters *)theSystemParameters { // Step 1: Select Data NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"SystemParameters" inManagedObjectContext:mManagedObjectContext]; [fetchRequest setEntity:entity]; NSError *error = nil; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; [fetchRequest release]; if (error) { NSLog(@"CoreData: saveSystemParametersToCoreData: Unresolved error %@, %@", error, [error userInfo]); abort(); } // Step 2: Update Object SystemParameters *systemParameters = [items objectAtIndex:0]; //// // GPS SIMULATOR //// [systemParameters setMGpsSimulatorEnabled:[theSystemParameters mGpsSimulatorEnabled]]; [systemParameters setMGpsSimulatorFileName:[theSystemParameters mGpsSimulatorFileName]]; [systemParameters setMGpsSimulatorPlaybackSpeed:[theSystemParameters mGpsSimulatorPlaybackSpeed]]; // Step 3: Save Updates [self saveAction]; } As to can see, I fetch the object that I want to update, change its values and save. Here is the saving code: - (void)saveAction { NSError *error; if (![[self mManagedObjectContext] save:&error]) { NSLog(@"ERROR:saveAction. Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } The Persistent store method: - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (mPersistentStoreCoordinator != nil) { return mPersistentStoreCoordinator; } NSString *path = [self databasePath]; NSURL *storeUrl = [NSURL fileURLWithPath:path]; NSError *error = nil; mPersistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![mPersistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:nil error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return mPersistentStoreCoordinator; } There is no error but the sqLite file is not updated, hence the data is not persistent. Thanks in advance.

    I've an access database table with 3 fields : Purchase date Warranty time Warranty expiry Warranty time has 1, 2, 3, 4, 5 in it which corresponds to years.
