• Associating logging from two or more processes

  - by Fadeproof

  I have two processes that I have up and running and I am doing logging from. One is a client the other is a webservice. I want to setup a central log system where I can track logs and interactions between processes -- for instance I want to be able to associate calls made from the client to the webservice when I look at the logs. I guess this means that somehow the processid of the client process needs to flow over to the webservice in some way for it to be trackable? Is this possible with current logging frameworks such as Enterprise Library or Log4Net? Is there anyone that has looked into something like this? Any help would be appreciated. If you have a more defining term for this please feel free to change the title of the question or tags.

• Is it possible to find out what FlashBuilder is doing during compilation?

  - by justkevin

  I've found that Flash Builder 4 (formerly Flex Builder) has trouble working with large projects. After a certain point, builds seem to take longer and longer. I've tried many different ways of improving build time including: Moving embedded resources into externally linked projects. Using -incremental. Tweaking the .ini jvm settings including memory and -server. Turning off automatic build (I'd prefer not to have to do this, because one of the main reasons for using an IDE is to be told about errors as you make them). Deleting the project and re-checking out from the repository. While some of these may help a bit, the performance is still annoyingly slow. I feel if I knew what was taking so long I could refactor my projects to build faster. Is there some setting that tells FlashBuilder to let me see what parts of the build process take so much time?

• how to integrate Zend Framework MVC with existing site

  - by Joel

  Hi guys, So I'm slowly tackling OO and Zend Framework and their MVC process in particular. I have an existing website and web-based calendar application that was designed by me, but coded by a different person and done procedurally. I understand that it will be very difficult for my application to ever be completely OO without a full re-write, and I'm fine with that. I have a lot of updates and modifications I want to do in the future, so I'm wanting to start replacing some of the basic components (login, authentication. etc) now, and continue to learn as I go. Again, I'm really a newbie at programming and OO. What I'm wondering is if I'm wanting to incorporate the Framework, then would I just first drop my whole site into the /public folder of the Framework and then start pulling functionality out from there?

• Can EPD Python and MacPorts Python coexist on OS X (matplotlib)?

  - by bjoern

  I've been using MacPorts Python 2.6 on OS X 10.6. I am considering also installing the Enthought Python Distribution (EPD) on the same machine because it comes preconfigured with matplotlib and other nice data analysis and visualization packages. Can the two Python distributions co-exist peacefully on the same machine? What potential problems will I have to look out for (e.g., environment variables)? I know that building matplotlib through MacPorts is an option, but the process is lengthy (on the order of a full day) and there are open questions about compiling some dependencies on 64bit Intel. I would like to know about the tradeoffs before committing to one of the two approaches.

• PHP file copy to another server; Access filesystem on other server

  - by dclowd9901

  I'm trying to write a PHP script to copy the files from your local machine to a server: $destination_directory = 'I:\path\to\file\\' . $theme_number; if(!@opendir($desination_directory)) { echo 'Sorry, the destination directory could not be found.'; die(); } I check the access to the destination folder with that process, and I keep getting the error return. Anyone know what I'm doing wrong? I pretty much have everything else in place. I just don't know how to access this other server.

• Show file extensions in document libraries in Sharepoint 2010

  - by sebastian

  I've got a Sharepoint site collection with several sub sites each having their own document library. Now I want to add the file extensions to the document names in all those libraries. How should I do this? I've seen tips telling you to modify the onet.xml-file, but they never look like mine do, and furthermore I don't know for sure what happens to that onet.xml-file - does it change the existing libraries? Other tips tell me to use Sharepoint designer, that would mean I'll have to do it for every view in every library, wouldn't it? So I'd prefer doing it from code, where I feel more comfortable and where I can automate the process. So, all I want is to replace the "Name (linked to document with edit menu)" with the "Name (for use in forms)" but still keep the link and the edit menu. I've found I need to use the FileLeafRef-field, but I don't know how! Thankful for any new clues, Sebastian

• Facebook photo additions showing as separate / individual posts

  - by user1143693

  When posting additional photos to an existing Facebook album, each individual photo is being displayed on the mobile Facebook view as a separate post. Desktop display still groups them (correctly) into 1 album and shows as a single post. For instance, if I add 20 photos to an album, the people who have liked my page will see 20 individual posts in their feed from my account on their mobile devices. This has been happening for about 2 weeks now as far as I've noticed. My upload process has not changed. I should note that I've noticed this behavior by uploading via Lightroom as well as through the direct Facebook interface. Has anyone else experienced this? Did something change that I am not aware of? Thanks.

• Why does java have an interpreter? and not a compiler?

  - by Galaxin

  Iam a newbie to java and was wondering why java have a interpreter and not a compiler? While shifting from c++ to java we come across the differences between these two Compilation process being one of them. 1.A major difference between a compiler and interpreter is that compiler compiles the whole code at once and displays all the errors at a time whereas an interpreter interprets line by line. 2.Also a compiler takes a less time to compile a code when compared to an interpreter. When java was developed for more advanced and easy features and implementations why has it been restricted to a interpreter based on above facts? Is there any special reason why this is so? If yes what is it?

• Building a world matrix

  - by DeadMG

  When building a world projection matrix from scale, rotate, translate matrices, then the translation matrix must be the last in the process, right? Else you'll be scaling or rotating your translations. Do scale and rotate need to go in a specific order? Right now I've got std::for_each(objects.begin(), objects.end(), [&, this](D3D93DObject* ptr) { D3DXMATRIX WVP; D3DXMATRIX translation, rotationX, rotationY, rotationZ, scale; D3DXMatrixTranslation(&translation, ptr->position.x, ptr->position.y, ptr->position.z); D3DXMatrixRotationX(&rotationX, ptr->rotation.x); D3DXMatrixRotationY(&rotationY, ptr->rotation.y); D3DXMatrixRotationZ(&rotationZ, ptr->rotation.z); D3DXMatrixScaling(&translation, ptr->scale.x, ptr->scale.y, ptr->scale.z); WVP = rotationX * rotationY * rotationZ * scale * translation * ViewProjectionMatrix; });

• Scala : cleanest way to recursively parse files checking for multiple strings

  - by fred basset

  Hi All, I want to write a Scala script to recursively process all files in a directory. For each file I'd like to see if there are any cases where a string occurs at line X and line X - 2. If a case like that occurs I'd like to stop processing that file, and add that filename to a map of filenames to occurrence counts. I just started learning Scala today, I've got the file recurse code working, and need some help with the string searching, here's what I have so far: import java.io.File import scala.io.Source val s1= "CmdNum = 506" val s2 = "Data = [0000,]" def processFile(f: File) { val lines = scala.io.Source.fromFile(f).getLines.toArray for (i = 0 to lines.length - 1) { // want to do string searches here, see if line contains s1 and line two lines above also contains s1 //println(lines(i)) } } def recursiveListFiles(f: File): Array[File] = { val these = f.listFiles if (these != null) { for (i = 0 to these.length - 1) { if (these(i).isFile) { processFile(these(i)) } } these ++ these.filter(_.isDirectory).flatMap(recursiveListFiles) } else { Array[File]() } } println(recursiveListFiles(new File(args(0))))

• How can I compile an autotools project with statically linked dependancies?

  - by flyx

  There's an open source library I want to use. As I want to spread my software as binary package, I do not want the library to have dependancies on other libraries, so I need to link the dependancies statically. Now as the library is open source and there are no binaries provided, I compile it myself. The library uses autotools, and I didn't find any useful documentation on how to link dependancies statically. What I did try is to call the configure script with --enable-static, but this apparently only tells configure to compile a static version of the library - but what I need is a dynamic library that includes all the libraries it depends on. So, I need a way to either tell configure to link against dependancies statically, or a way to post-process the built library to include all dependancies. Can anyone tell me how to do this? Oh, and if it matters: I'm on 64bit Snow Leopard.

• What system does before launching iPhone app's main() function?

  - by Eonil

  My app takes too much time to loading. So I put a NSLog in main() function like this to measure loading time from first: int main(int argc, char *argv[]) { NSLog(@"main"); NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, nil); [pool release]; return retVal; } But, the log displayed at really later time. Default.png displayed about 5 seconds, all loading process completed in 1~2 seconds after log appeared. What's happening before executing main() function on iPhone app?

• Run batch file when argument contains quotes and spaces (from .NET framework)

  - by turtle

  I have a bat file which sets some environment variables, and then executes a command on the command line. I want to replace the hard coded command with one passed in via a parameter. So: :: Set up the required environment SET some_var=a SET another_var=b CALL some.bat :: Now call the command passed into this batch file %1 The problem is that the command is complex, and doesn't escape cleanly. It looks like this: an.exe -p="path with spaces" -t="some text" -f="another path with spaces" I'm trying to call the .bat from a .NET framework app, using: Dim cmd as String = "the cmd" System.Diagnostics.Process.Start( thebat.exe, cmd ) but I can't seem to get the escapes to work correctly. Can someone tell me how the string cmd should be entetered to get the command passed into the bat file as an argument correctly?

• Why does the android emulator camera stop unexpectedly?

  - by user490074

  I am using Android 2.2 (API Level 8). The camera is enabled in the manifest. When I try the camera icon provided by the emulator model, it runs for a few seconds showing a gray box moving around a black and white checkerboard, then dies with the error message: Sorry! The application Camera (process com.android.camera) has stopped unexpectedly. Please try again. Trying again, of course, doesn't help. I am using the provided emulator camera to compare behavior with a camera application I am working on. Why does the android emulator camera stop unexpectedly?

• n00b: receive input over TCP/IP and use it to update HTML

  - by mawg

  This has got to be a FAQ, so can someone please just direct me to a "network programming for dummies" URL? The server wants to push information to a client or broadcast to all, when an event happens - as opposed to the clients constantly polling the server "just in case". The client then updates a browser page display. How do I do that? (toldya it was a n00b question) Should I have a thread which receives info on a socket and then writes it to a database which the browser display (PHP) can process with an HTML refresh tag, or what? Sorry to sound so dumb.

• How to create a Windows GUI with a file explorer window, allowing users to choose files?

  - by Badri

  Here's what I want to do. I want to present a file explorer, and allow the user to select files, and list the selected files below. (I then want to process those files but that's the next part) For example, the way CD Burning softwares work. I have created a mock up here http://dl.dropbox.com/u/113967/Mockup.png As you can see, the left frame has a directory structure, the right frame has a file selected, and the bottom frame shows the selected file. What framework can I go about creating this? I am familiar with command line C++ stuff, but I haven't ventured into any GUI programming, and figured this idea would be a good place to start. Any suggestions on where to start?

• Serving large generated files using Google App Engine?

  - by John Carter

  Hiya, Presently I have a GAE app that does some offline processing (backs up a user's data), and generates a file that's somewhere in the neighbourhood of 10 - 100 MB. I'm not sure of the best way to serve this file to the user. The two options I'm considering are: Adding some code to the offline processing code that 'spoofs' it as a form upload to the blob store, and going thru the normal blobstore process to serve the file. Having the offline processing code store the file somewhere off of GAE, and serving it from there. Is there a much better approach I'm overlooking? I'm guessing this is functionality that isn't well suited to GAE. I had thought of storing in the datastore as db.Text or Dd.Blob but there I encounter the 1 MB limit. Any input would be appreciated,

• Proper error handling in a custom Zend_Autoloader?

  - by Pekka

  I'm building a custom autoloader based on Zend Framework's autoloading (related question here). The basic approach, taken from that question, is class My_Autoloader implements Zend_Loader_Autoloader_Interface { public function autoload($class) { // add your logic to find the required classes in here } } and then binding the new autoloader class to a class prefix. Now what I'm unsure about is how to handle errors inside the autoload method (for example, "class file not found") in a proper, ZF compliant way. I'm new to the framework, its conventions and style. Do I quietly return false and let the class creation process crash? Do I output an error or log message somehow (which would be nice to pinpoint the problem) and return false? If so, what is the Zend way of doing that? Do I trigger an error? Do I throw an exception? If so, what kind?

• Dynamically create PHPUnit tests from data-file

  - by DeletedAccount

  I have a data file with input and expected outputs. An example could be: input: output: 2 3 3 5 4 Exception 5 8 ... ... Currently I have a custom solution to read from the data file and perform a test for each {input,output} pair. I would like to convert this into a PHPUnit based solution and I would like to have one test per input using the test name forXassertY. So the first three tests would be called for2assert3(), for3assert5() and for4assertException(). I do not want to convert my existing data to tests if it's possible to create the test methods dynamically and keep the data file as the basis of these tests. I want to convert it to PHPUnit as I want to add some other tests later on and also process and view the output using Hudson. Suggestions?

• What is the correct way to tell if Pango has found the right font?

  - by Thedward

  I create a font description with: pango_font_description_from_string() Then load a font with: pango_context_load_font() This process seems to result in some default font regardless of the string I give it. Is there any sane way for me to determine if the returned font is the result of an alias (e.g. "Sans", "Monospace") or just the last chance default font? For example, if I request the font "Monospace" and get back "DejaVu Sans Mono" then I should be able to declare that a good match. However, if I request "OquieZee" and get back "DejaVu Sans" then I'd like to know that I just got back the default font because the font I requested doesn't actually exist on the system. When I first saw pango_font_description_better_match() I thought it might be of help, but it turned out to be a dead end.

• How to presist the user authentication in SL3 + RIA

  - by Nair

  I am developing SL3 + RIA services with custom authentication. I followed the example in http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2661 to implement custom authentication. Based on the implementation, you first do login request from client to service. This request is async process. Since login is async, the control will go back to GUI which then starts to do data bind in SL controls using RIA services, the services happens to requires the authentication to be successful (by adding [RequireAuthentication] attribute). The trouble is, since you requested login might not have completed before the data binding starts t this stage the authentication is false because of that data binding will fail. I would like to know if you require your web services to have 'RequireAuthentication' how would you wait for authentication to complete at the server side or client side. Appriciate the help. Thanks,

• Preloading images from XML into Flash
