• Log4j Dynamic Parameter

  - by cedric

  Hi. i have a j2ee web application running on spring framework and using log4j for logging. I have this line in my log4j.properties file. this will insert the logs in my database. How do I set a dynamic value in the message part so that I can somehow append the currently logged in user. The bean object containing info for the current user is in the application context. log4j.appender.dbLog.sql = INSERT INTO LOGGING (log_date, log_level, location, message) VALUES ('%d{yyyy/MM/dd HH:mm:ss}', '%-5p', '%C-%L', '%m')

• very quickly getting total size of folder

  - by freakazo

  I want to quickly find the total size of any folder using python. def GetFolderSize(path): TotalSize = 0 for item in os.walk(path): for file in item[2]: try: TotalSize = TotalSize + getsize(join(item[0], file)) except: print("error with file: " + join(item[0], file)) return TotalSize That's the simple script I wrote to get the total size of the folder, it took around 60 seconds (+-5 seconds). By using multiprocessing I got it down to 23 seconds on a quad core machine. Using the Windows file explorer it takes only ~3 seconds (Right click- properties to see for yourself). So is there a faster way of finding the total size of a folder close to the speed that windows can do it? Windows 7, python 2.6 (Did searches but most of the time people used a very similar method to my own) Thanks in advance.

• McAfee Virus Scan and Oracle RAC

  - by Lee Gathercole

  Hi, We're experiencing a strange problem with Oracle RAC and McAfee anti-virus. As part of the installation of the Oracle RAC we disable anti virus as directed. We have had our RAC running fine, but when we came to re-enable the AV and reboot we got the BSOD. Abnormal Program Termination (BugCheck, STOP: 0x00000035 (0x8E984678, 0x00000000, 0x00000000, 0x00000000 NO_MORE_IRP_STACK_LOCATIONS Following the standard process of raising this problem with Microsoft they identify the problem and also a fix. Microsoft talk about too many file filter drivers being present and pushing the DFS upper limit beyond the default size. Upping this value, as per msdn, has no impact. We're able to recover from this BSOD by disabling AV. We don't have the problem if we run the AV service manually whilst the system is up. However, if we make the service automatic we fail to boot.

• How to add a dynamic library to Android?

  - by Malcolm

  I want to add a non-native shared library to Android so every application on the device would be able to use it. I mean using packaged classes just like a core library as if they were present in the application itself. I studied Android source code to figure out a way to add a new path to the application ClassLoader and found out that it is created during startup and there's no way to change the paths later. I can use my own ClassLoader, but all I will get after loading a class will be a reference to a Class object. This way I will be bound to work through reflection mechanism, which is slower than the native execution system. Is there any way to organise a shared library on Android?

• Mac OS X, Can't start/stop MySQL via System Preferences

  - by Steve Kuo

  I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

• Grails 1.2.1 with Spring 3.0.0 dependency problem under Jetty

  - by archer

  Just moved to Grails 1.2.1 (used 1.1.1 before). Changed application.properties, ran grails upgrade, fixed BuildConfig and Bootstrap - everything works just fine from grails console. However, getting a problem when deploy packaged war under jetty 6.1.22: 1581 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is java.lang.NoSuchMethodError: org.codehaus.groovy.grails.commons.spring.ReloadAwareAutowireCapableBeanFactory.setParameterNameDiscoverer(Lorg/springframework/core/ParameterNameDiscoverer;)V My project is built with maven2. I researched the war dependencies and see that both spring 2.5.6 and 3.0.0.RELEASE are used there. I then tried to suppress use of spring 2.5.6 and got a problem with Acegi plugin (using version 0.5.1): 2010-03-10 21:06:56.440:WARN::Nested in org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is java.lang.NoSuchMethodError: org.springframework.web.context.ConfigurableWebApplicationContext.setId(Ljava/lang/String;)V Any help would be greatly appreciated.

• List of header file locations for the Havok Physics Engine

  - by QAH

  Hello everyone! I am trying to integrate the Havok physics engine into my small game. It is a really nice SDK, but the header files are all over the place. Many headers are deeply nested in multiple directories. That gets confusing when you are trying to include headers for different important objects. I would like to know if there is a nice guide that will let you know where certian objects are and what headres they are in. I have already looked at Havok's documentation, and I also looked at the reference manual, but they don't give great detail as to where certain classes are located (header location). Also, is there any programs out there that can scan header files and create a list of where objects can be found? Thanks again

• ShowDialog won't run

  - by clawson

  I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog() but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong. When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it. Any idea what may cause this to happen, or what I should be looking for that might be causing the problem?? Thanks for the help!

• Anyone using NoSQL databases for medical record storage?

  - by Brian Bay

  Electronic Medical records are composed of different types of data. Visit information ( date/location/insurance info) seems to lend itself to a RDMS. Other types of medical infomation, such as lab reports, x-rays, photos, and electronic signatures, are document based and would seem to be a good candidate for a 'document-oriented' database, such as MongoDB. Traditionally, binary data would be stored as a BLOB in a RDBMS. A hybrid approach using a traditional RDBMS along with a 'document-oriented' database would seem like good alternative to this. Other alternative would be something like DB2 purexml. The ultimate answer could be that 'it depends', but I really just wanted to get some general feedback/ideas on this. Is anyone using the NoSql approach for medical records?

• Flash video hiding the cursor on Mac OS X

  - by Tibor

  I found a Core Graphics function, CGCursorIsVisible, that one can use to determine whether the mouse cursor is shown on screen. I have a small app that uses a timer to call that function a few times a second to see if the cursor is shown or hidden (as I found no way to get my app notified when the mouse cursor shown/hidden status changes). The above works correctly except… when the Flash browser plugin plays a video: the mouse cursor gets hidden after a few seconds of mouse inactivity but CGCursorIsVisible() still keeps telling me that the cursor is indeed shown as if nothing happened. What I need is to be able to tell, at any given moment, whether the mouse cursor is shown to the end user on any screen. Is there any way to do that even in the case of playing a video using the Flash plugin?

• Extract files from ZIP file with VBScript

  - by Tester101

  When extracting files from a ZIP file I was using the following. Sub Unzip(strFile) ' This routine unzips a file. NOTE: The files are extracted to a folder ' ' in the same location using the name of the file minus the extension. ' ' EX. C:\Test.zip will be extracted to C:\Test ' 'strFile (String) = Full path and filename of the file to be unzipped. ' Dim arrFile arrFile = Split(strFile, ".")

What is the reason for this? Are there any alternatives?

• Safari will not redirect to querystring URL

  - by alooficha

  I have a site built with PHP that does a redirect after certain actions are performed. header("Location: http://example.com/accountArea/?v=updated"); I then show a message based on the value of the query string value. In safari (and only in Safari) after the redirect, you will only see a blank page. I have tried using absolute URL and relative URL in my redirect, neither work. I was unable to find a solution by searching the web so I hope someone here is familiar with this.

• Missing [mx.rpc]::IResponder

  - by Arms

  I'm trying to use the Flex 4 SDK's mx.rpc package in a Flash application. I imported Flex's rpc.swc (Adobe\Adobe Flash Builder 4\sdks\4.0.0\frameworks\libs\rpc.swc) into my project by adding it to the list in Flash's "Publish Settings/Flash/ActionScrip 3.0 Settings/Library Path". It seems like I have access to the classes, however when I compile I get this error: 1046: Type was not found or was not a compile-time constant: [mx.rpc]::IResponder. There's no location or line for the error either. Any idea how to get this to work? TIA! Notes: I'm using Flash Builder 4 and Flash CS5

• Problem with javascript in firefox when moving google ads

  - by thomas woelfer

  hi. i have a website with google ads on it. i would like to make it load faster. thus i moved all the google scripts to the bottom of the page. i also have a placeholder at the location where the ad(s) should be displayed and other divs that (initially) get the ads. finally (in window.onload) i'm moving the ads that have just be fetched from google to their target locations. (a simple example page is here: http://www.nickles.de/temp/ads.html ) this works in ie, but it doesn't work in ff. (that is, in firefox, non-text ads show up fine, while text-ads don't. [or at least, not in a reliable way.]) any ideas what would be causing this? Thanks! -thomas woelfer

• iPhone SDK: CLocationAccuracy. What constants map to what positioning technology?

  - by buzzappsoftware

  With respect to CLocationManager docs.... Constant values you can use to specify the accuracy of a location. extern const CLLocationAccuracy kCLLocationAccuracyBestForNavigation; extern const CLLocationAccuracy kCLLocationAccuracyBest; extern const CLLocationAccuracy kCLLocationAccuracyNearestTenMeters; extern const CLLocationAccuracy kCLLocationAccuracyHundredMeters; extern const CLLocationAccuracy kCLLocationAccuracyKilometer; extern const CLLocationAccuracy kCLLocationAccuracyThreeKilometers; Given that, I have the following questions. What triangulation method (GPS, cell tower or wi-fi) corresponds to each accuracy level? Does iPhone SDK utilize Skyhook Wireless API? For kCLLocationAccuracyBestForNavigation, there is note stating the phone must be plugged in. Is this enforced or is it just warning the developer the battery is likely to drain quick from using the GPS receiver. Thanks in advance.

• Are keys and values of %INC platform-dependent or not?

  - by codeholic

  I'd like to get the full filename of an included module. Consider this code: package MyTest; my $path = join '/', split /::/, __PACKAGE__; $path .= ".pm"; print "$INC{$path}\n"; 1; $ perl -Ipath/to/module -MMyTest -e0 path/to/module/MyTest.pm Will it work on all platforms? perlvar The hash %INC contains entries for each filename included via the do, require, or useoperators. The key is the filename you specified (with module names converted to pathnames), and the value is the location of the file found. Are these keys platform-dependent or not? Should I use File::Spec or what? At least ActivePerl on win32 uses / instead of \. Update: What about %INC values? Are they platform-dependent?

• Trouble with Powershell and running a complex commandline

I assure you, the path does exist with the space in it on my machine. What's the best way to call this command line from Powershell? I've tried Invoke-Expression, Diagnostic.Process::Start, &; each method coming up with some different type of error; usually that it could find the executable. Any constructive input is greatly appreciated. Thanks.

• Best practice for sharing code between OSX and IOS app

  - by Alberto

  I am creating an iOS version of an existing OSX app and am wondering what the best practices are for sharing code between the two. The code in question only depends on the foundation framework and the Sqlite dynamic library, so it should compile and run fine on both platforms. It seems to me there are three possible options: Create a single project with and OSX and an IOS targets, add source files to each target as appropriate. Create two separate projects for the OSX and IOS apps, put shared code in a common location in the workspace and add it as reference to both projects. Create three projects: OSX app, IOS app and a shared static library with an OSX and an IOS targets; add each library target to the respective application. Is there any reason one of the above approaches may be better than the other two? If not, option 2 seems to be the simplest by far.

• Is there a way to put relationships/contraints into CSS?

  - by hekevintran

  In every design tool or art principle I've heard of, relationships are a central theme. By relationships I mean the thing you can do in Adobe Illustrator to specify that the height of one shape is equal to half the height of another. You cannot express this information in CSS. CSS hard-codes all values. Using a language like LESS that allows variables and arithmetic you can get closer to relationships but it's still a CSS variant. This inability in my mind is the biggest problem with CSS. CSS is supposed to be a language that describes the visual component of a Web page but it ignores relationships and contraints, ideas that are at the core of art. How possible is it to imagine a new Web design language that can express relationships and contraints that can be implemented in JavaScript using the current CSS properties?

• Redmon's Run As User not loading user's enviroment variables

  - by catfish

  I'm attempting to use Redmon http://www.winimage.com/misc/redmon/ to send print jobs to a custom C# application. Redmon "runs" (actually the Print Spooler) as SYSTEM but has an option to Run As User to allow your application to run under the user that printed the job. The problem is that it doesn't appear to load the user's environment. So calling functions like Path.GetTempPath() points to \windows\temp instead of the user's. Also when attempting to run Outlook 2007+ via MAPI calls (to add attachments) it reports form errors due to, I think, the temp folder location. Is there a way to "reload" a profile or atleast get your environment vars within the Impersonated application? The only ideas I've had so far is to rebuild the vars directly from the registry, but I want to avoid this since it's a hack around (avoiding implementation details and all that). Or making a stub program that Redmon calls which then properly Run As User with full profile the custom application. Any other items or tricks?

• Linux: file recovery (Urgent) [closed]

  - by Ashine

  Hi Firends, I desperately need some help regarding problem I am facing now. While creating a softlink for a very important file I gave the reverse command by mistake. Instead of giving it "ln target linkname" I have given it 'ln linkname target'. This has resulted in references pointing to target files are now pointing to links and the actual refernces to target files are lost. How can I recover the files back. "/home/user/data1" was original file location. "/home/user/db2" was the desired softlink for this data. I haveto give "ln data1 db2" but I have given 'ln db2 data1'. This has resulted in 'data1' being now pointing towards 'db2' and the actual data in 'data1' can not be retrieved. Some one please help. Thanks in advance.
