  • Missing ant-javamail.jar file on Macintosh

    - by Ken
    I've been running the built-in Ant from the command line on a Macintosh (10.5.5) and have run into some trouble with the Mail task. Running the Mail task produces the following message: [mail] Failed to initialise MIME mail: org.apache.tools.ant.taskdefs.email.MimeMailer This is most likely due to a missing ant-javamail.jar file in the /usr/share/ant/lib directory. I see a "ant-javamail-1.7.0.pom" file in this directory but not the appropriate jar file. Anyone know why this jar file might be missing and what the best way to resolve the problem is?

  • How do I make C++/wxWidgets code accessible to a wxPython app?

    - by Jon Cage
    I have a code library which is written in C++ and makes extensive use of the wxWidgets library.

  • Disable Crossfire on an ATI HD 5970

    - by cdecker
    I'm trying to create a computation cluster using ATI GPUs. The problem is that I have to disable Crossfire in order to get maximum performance out of the ATI Radeon HD 5970 I bought to get started, but no matter what I do I can't disable it. The problem is that I'd like to run an OpenCL application on the two cores in parallel, but right now they just interfere with each other. Any idea on how to do so under Ubuntu Linux, with ATI Catalyst 10.10?

  • Run SSIS package from SQL client

    - by Pramodtech
    I deployed my working package on server which is enterprise edition, SSIS installed on it. When I tries to run package by connecting to integration services engine from my desktop SQL client (which doesn't have SSIS installed) I get error "The task "Send Mail Task" cannot run on this edition of Integration Services. It requires a higher level edition." Does it mean that I need to login to the server (RDP) and then run the package? Also, when I schedule the package thru SQL agent it fails saying login time out but my windos auth login works for everything from connecting, deployment. Any clue?

  • Using Unit Tests While Developing Static Libraries in Obj-C

    - by macinjosh
    I'm developing a static library in Obj-C for a CocoaTouch project. I've added unit testing to my Xcode project by using the built in OCUnit framework. I can run tests successfully upon building the project and everything looks good. However I'm a little confused about something. Part of what the static library does is to connect to a URL and download the resource there. I constructed a test case that invokes the method that creates a connection and ensures the connection is successful. However when my tests run a connection is never made to my testing web server (where the connection is set to go). It seems my code is not actually being ran when the tests happen? Also, I am doing some NSLog calls in the unit tests and the code they run, but I never see those. I'm new to unit testing so I'm obviously not fully grasping what is going on here. Can anyone help me out here? P.S. By the way these are "Logical Tests" as Apple calls them so they are not linked against the library, instead the implementation files are included in the testing target.

  • KeepAlive packets over a Soap request

    - by Nycto
    I've been debugging some Soap requests we are making between two servers on the same VLAN. The app on one server is written in PHP, the app on the other is written in Java. I can control and make changes to the PHP code, but I can't affect the Java server. The PHP app forms the XML using the DOMDocument objects, then sends the request using the cURL extension. When the soap request took longer than 5 minutes to complete, it would always wait until the max timeout limit and exit with a message like this: Operation timed out after 900000 milliseconds with 0 bytes received After sniffing the packets that were being sent, it turns out that the problem was caused by a 5 minute timeout in the network that was closing what it thought was a stale connection. There were two ways to fix it: bump up the timeout in iptables, or start sending KeepAlive packets over the request. To be thorough, I would like to implement both solutions. Bumping up the timeout was easy for ops to do, but sending KeepAlive packets is turning out to be difficult. The cURL library itself supports this (see the --keepalive-time flag for the CLI app), but it doesn't appear that this has been implemented in the PHP cURL library. I even checked the source to make sure it wasn't an undocumented feature. So my question is this: How the heck can I get these packets sent? I see a few clear options, but I don't like any of them: Write a wrapper that will kick off the request by shell_execing the CLI app. This is a hack that I just don't like Update the cURL extension to support this. This is a non-option according to Ops. Open the socket myself. I know just enough to be dangerous. I also haven't seen a way to do this with fsockopen, but I could be missing something. Switch to another library. What exists that supports this? Thanks for any help you can offer.

  • System.Threading.Tasks - Limit the number of concurrent Tasks

    - by James
    I have just started to look at the new "System.Threading.Tasks" goodness in .Net 4.0, and would like to know if there is any build in support for limiting the number of concurrent tasks that run at once, or if this should be manually handled. E.G: If I need to call a calculation method 100 times, is there a way to set up 100 Tasks, but have only 5 execute simultaneously? The answer may just be to create 5 tasks, call Task.WaitAny, and create a new Task as each previous one finishes. I just want to make sure I am not missing a trick if there is a better way to do this. Thanks for any help.

  • Crontab + rails3 + bundler

    - by mendelbenjamin
    I'm running a crontab that executes a rake task. I'm getting the following error (with MAILTO from crontab): rake aborted! no such file to load -- bundler /Users/Mendel/Sites/misnooit/Rakefile:4 (See full trace by running task with --trace) I'm using rvm with: ruby: ruby 1.9.1p378 rails: Rails 3.0.0.beta $GEM_HOME: /Users/Mendel/.rvm/gems/ruby-1.9.1-p378 bundler: bundler (0.9.11) The error is pretty self explanatory but I'm not able to fix it.. Is there someone with more knowledge about this matter? Thanks in advance.

  • Compiling a DLL which includes Ogre3D gives an assertion error when used

    - by samaursa
    Hi, I have a framework that I am building and is being compiled into a static library to be used by other projects. The library works perfectly without issues. The problem is that the link time is very long for the projects that use the library so I thought I will make a DLL project of the same framework. I started with baby steps and created an MFC DLL project through visual studio. The project has the following header: /// -------------------------------------------- #ifndef OGRECORE_H #define OGRECORE_H #ifdef OGREFW_EXPORT #define OGREFW_DLL __declspec(dllexport) #else #define OGREFW_DLL __declspec(dllimport) #endif class OgreRoot; namespace OgreFW { class OGREFW_DLL OgreCore// : public OIS::KeyListener, public OIS::MouseListener { public: OgreCore(); ~OgreCore(); }; }; #endif // OGRECORE_H and this is the source #include "stdafx.h" #include "OgreCore.h" //#include "Ogre.h" //#include "OgreRoot.h" //#include "OgreRenderWindow.h" //#include "OgreLog.h" //#include "OgreLogManager.h" //#include "OgreOverlay.h" //#include "OgreViewport.h" //#include "OgreRenderWindow.h" //#include "OgreFrameListener.h" //#include "OgreWindowEventUtilities.h" //#include "OgreSceneNode.h" //#include "OgreEntity.h" //#include "OgreManualObject.h" //#include "OgreMeshManager.h" //#include "OgreConfigFile.h" //#include "OgreOverlayContainer.h" //#include "OgreOverlayManager.h" namespace OgreFW { OGREFW_DLL OgreCore::OgreCore() { } // ------------------------ OGREFW_DLL OgreCore::~OgreCore() { } } As you can see I have commented out Ogre includes. When a project uses the compiled DLL and constructs this (OgreCore) class, it works perfectly fine. As soon as uncomment one of the Ogre includes and compile the DLL again, the project that uses the DLL now gives an assertion error. The full details can be found here in the Ogre forum post. I posted the question there first but since its not really an Ogre specific question I thought I will try here as well. The link to the Ogre post is: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=58403 Thank you in advance

  • Expanding globs in xargs

    - by Craig
    I have a directory like this mkdir test cd test touch file{0,1}.txt otherfile{0,1}.txt stuff{0,1}.txt I want to run some command such as ls on certain types of files in the directory and have the * (glob) expand to all possibilities for the filename. echo 'file otherfile' | tr ' ' '\n' | xargs -I % ls %*.txt This command does not expand the glob and tries to look for the literal 'file*.txt' How do I write a similar command that expands the globs? (I want to use xargs so the command can be run in parallel)

  • XML to DOC to PDF

    - by Max
    what is the easiest(and fastest) way to perform this kind of transformation: "Data in XML" to "Some MS Word 2003 Supported format" to PDF using Java? My first guess was to fill the template with XML data (using Placeholders for example) and then save it and convert it to PDF. But I can't just put placeholders to DOC files, and I can't convert from some other Word formats to PDF... My primary task is to convert XML Data to PDF allowing users to change the PDF on-demand. The best way to change the PDF on-demand seems to give user some kind of MS Word readable document, and then convert it back. There are 2 main problems with this task: 1) I can't use OpenOffice for conversion. 2) System should be able to convert ~1 page of table-based document per 1 second on 2Ghz Core. 3) RTF does not provide enough styling, so some more complex format should be used. Thanks in advance.

  • Graphviz or Dynagraph for Graph-manipulation Program?

    - by noahlavine
    I'm looking into writing a program that will show a graph to the user. The graph will change over time (the user should be able to right-click on a graph item and ask for more detail, which will pop out new bits of the graph), and the user might be able to drag parts of the graph around. I would ideally also like to be able to specify the relative layout of certain parts of the graph myself while leaving the overall layout up to a library, but that's not essential. I'm trying to decide on a graph layout library to use. As far as I can tell, the two leading candidates are Graphviz and Dynagraph. The Dynagraph website suggests that Graphviz is for drawing static graphs, and that Dynagraph was forked from Graphviz and contains algorithms for graphs that will be updated. It has a sample program called Dynasty that does exactly what I want. However, the Graphviz site contains an example program called Lefty which seems to do exactly what I want. Graphviz also seems to be much more widely used, judging by Google (and SO) results. Finally, I'd like to code the GUI part in a language like Python or Scheme, which makes me a bit hesitant to use C++ because I understand it's harder to interface that to interpreters. So my question is, which library is better for what I'm trying to do? Do they both have strong and weak points? Has one of them actually ceased development and is just leaving its website up to confuse me? (I've seen http://stackoverflow.com/questions/464000/simple-dynamic-graph-display-for-c and http://stackoverflow.com/questions/2376987/open-source-libraries-to-design-directed-graphs, but I can't tell whether they're right about the Graphviz or Dynagraph choice because of Lefty and also the language issue.)

  • GH-Unit for unit testing Objective-C code, why am I getting linking errors?

    - by djhworld
    Hi there, I'm trying to dive into the quite frankly terrible world of unit testing using Xcode (such a convoluted process it seems.) Basically I have this test class, attempting to test my Show.h class #import <GHUnit/GHUnit.h> #import "Show.h" @interface ShowTest : GHTestCase { } @end @implementation ShowTest - (void)testShowCreate { Show *s = [[Show alloc] init]; GHAssertNotNil(s,@"Was nil."); } @end However when I try to build and run my tests it moans with this error: - Undefined symbols: "_OBJC_CLASS_$_Show", referenced from: __objc_classrefs__DATA@0 in ShowTest.o ld: symbol(s) not found collect2: ld returned 1 exit status Now I'm presuming this is a linking error. I tried following every step in the instructions located here: - http://github.com/gabriel/gh-unit/blob/master/README.md And step 2 of these instructions confused me: - In the Target 'Tests' Info window, General tab: Add a linked library, under Mac OS X 10.5 SDK section, select GHUnit.framework Add a linked library, select your project. Add a direct dependency, and select your project. (This will cause your application or framework to build before the test target.) How am I supposed to add my project to the linked library list when all it accepts it .dylib, .framework and .o files. I'm confused! Thanks for any help that is received.

  • SharePoint State Machine Workflow walkthrough

    - by d-frag
    I haven't seen an actual SharePoint state machine workflow example on here, but figured this post, How to create a SharePoint State Machine Workflow, is as thorough as it gets. Its a 6-part series. It has a step-by-step approach so even a 9 year old could just follow along and do it. It shows exactly how to use InfoPath to create the initiation form and task form, how to create the state machine workflow (with both C# and VB code), and also how to add workflow history logging and task notification emails. It does not go into modification forms, but does everything else, pretty much. Hope someone finds this useful.

  • Use bug tracker to get things done and manage personal tasks?

    - by Frank
    This is slightly off-topic, but can only be answered by programmers and is useful to many programmers: Do you think it is useful to use a bug tracking system to keep track of personal todo items and to Get Things Done? I have not tried that; in fact, I don't have much experience with bug tracking systems. For my todo lists, I have played around with Google Tasks and Remember The Milk, but both of them have shortcomings: Google Tasks: I like that you can create todo lists easily, can reorder items in the list and easily create hierarchies. But it is way too simplistic and does not allow to tag tasks or move tasks from one list to another. Remember The Milk: It is nice and sleek, but you cannot create hierarchies of tasks, cannot arbitrarily reorder tasks and cannot set dependencies of tasks. That's where a bug tracking system should come in: Since I think (maybe too much?) like a programmer, my tasks have a natural hierarchy and a tree of dependencies, like in a Makefile. Here are two examples: The task of writing my thesis is done when several milestones are done. Some of these milestones can run in parallel (writing background chapter, running experiments A, running experiments B), others depend on each other (writing main chapter depends on first getting results from experiments A). The same is true for more personal goals: I want to host a dinner party, which requires finding a good date, finishing the guest list, making invitations, finding nice recipes, cooking, ... For me, all these tasks involve hierarchical dependencies and milestones that bug tracking systems should be able to handle? Here is an article that explains how to do advanced GTD with Remember The Milk, but he has to use several workarounds: (1) add a general tag 'wait' to tasks that are waiting for others to be completed but you cannot enter the IDs of the tasks that they are waiting for, (2) starting some special tasks with "." so that they are at the top of the alphabetically sorted list and signal that others are 'below' it as subgoals. Bug tracking systems should be able to handle these things much more naturally? Does anyone have experience and can recommend a lightweight bug tracking system that might be good for this? Other requirements: Should run as web app, should allow me to tag a task with several tags (like 'work', 'fun', 'short-task', 'errands', ...).

  • Umbraco XSLT issue

    - by Brad
    I'm trying to use the Umbraco GetMedia function to write an image URL to the screen, I receive an error parsing the XSLT file. <xsl:for-each select="$currentPage/descendant::node [string(data [@alias='tickerItemActive']) = '1']"> <xsl:value-of select="data [@alias='tickerText']"/><br /> <xsl:value-of select="umbraco.library:GetMedia(data [@alias='tickerImage'], 0)/data [@alias = 'umbracoFile']"/> </xsl:for-each> The tickerImage field contains the MediaID for which I'd like to display the URL. I can return the field outside the GetMedia function and it works fine. I can also replace the data [@alias='tickerImage] with '1117' (or any valid media ID) the XSLT passes verification and the script runs. THIS WORKS: <xsl:value-of select="umbraco.library:GetMedia('1117', 0)/data [@alias = 'umbracoFile']"/> THIS DOES NOT: <xsl:value-of select="umbraco.library:GetMedia(data [@alias='tickerImage'], 0)/data [@alias = 'umbracoFile']"/> Any help that can be offered would is appreciated. Thanks!

  • Building java project with TFS

    - by Jaco Pretorius
    A very small portion of our codebase is some legacy Java code. I'm trying to add a new build that would invoke ant to build this project. The first problem is that TFS doesn't allow you to create a build that doesn't build a .Net solution. I got around this by copying a previous build file and adding an EndToEndIteration task which is the entry point for the build. The problem is that none of the usual build variables are populated - $(BuildDirectory), $(SolutionRoot) - all blank. This pretty much means I can't invoke my ant task without hardcoding the paths (which I definitely can't do). Any ideas?

  • What is the difference: LoadUserProfile -vs- RegOpenCurrentUser

    - by Will5801
    These two APIs are very similar but it is unclear what the differences are and when each should be used (Except that LoadUserProfile is specified for use with CreateProcessAsUser which I am not using. I am simply impersonating for hive accesss). LoadUserProfile http://msdn.microsoft.com/en-us/library/bb762281(VS.85).aspx RegOpenCurrentUser http://msdn.microsoft.com/en-us/library/ms724894(VS.85).aspx According to the Services & the Registry article: http://msdn.microsoft.com/en-us/library/ms685145(VS.85).aspx we should use RegOpenCurrentUser when impersonating. But what does/should RegOpenCurrentUser do if the user profile is roaming - should it load it? As far as I can tell from these docs, both APIs provide a handle to the HKEY_CURRENT_USER for the user the thread is impersonating. Therefore, they both "load" the hive i.e. lock it as a database file and give a handle to it for registry APIs. It might seem that LoadUserProfile loads the user profile in the same way as the User does when he/she logs on, whereas RegOpenCurrentUser does not - is this correct? What is the fundamental difference (if any) in how these two APIs mount the hive? What are the implications and differences (if any) between what happens IF A user logs-on or logs-off while each of these impersonated handles is already in use? A user is already logged-on when each matching close function (RegCloseKey and UnloadUserProfile) is called?

  • Heuristic algorithm for load balancing among threads.

    - by Il-Bhima
    I'm working on a multithreaded program where I have a number of worker threads performing tasks of unequal length. I want to load-balance the tasks to ensure that they do roughly the same amount of work. For task T_i I have a number c_i which provides a good approximation to the amount of work that is required for that task. I'm looking for an efficient (O(N) N = num tasks or better) algorithm which will give me "roughly" a good load balance given the values of c_i. It doesn't have to be optimal, but I would like to be able to have some theoretical bounds on how bad the resulting allocations are. Any ideas?

  • TFS and Project portal sync

    - by Tigran
    Just installed TFS 2008. Created a project with portal site. When I create a bug in TFS from Visual Studio I'd like to see that bug in the web portal. And the other way around. When I add a task in the web portal I'd like to see that in Visual Studio. It's as if the web portal is not connected to TFS. I'm using the MSF for Agile Software Development template. I just saw Team System Web Access. That's what I want in addition to the other pages Sharepoint portal provides. For example the Wiki page and calendar view. So one place to see all tasks lists and assign task and see other project related pages. Maybe be able to has the tasks due dates come up on the calendar. Many thanks

  • How to estimate the contribution of an individual to a software project?

    - by Amit Kumar
    I work on a software project and would like to estimate the percentage out of the total contribution that I have put in the development of the software. Is there some tool doing this? Such a tool can be useful for appraisals or negotiations, for example. After all, we work for money (yes, not only money, put the point remains). I think there is enough hand-waving for the most important things. The estimation is very subjective (at least to me now) but I do not know of any tool that provides even a subjective estimate. I know of Sloccount that spells out the total effort using the lines of code but not on per-developer basis. My idea of an ideal tool for this purpose would: measure the complexity of the code (more complex is more effort, but more effort is not necessarily more contribution) measure the decomposibility/flexibility of the software (more decomposable is better) how much library code is used -- using library code speeds up the development process, increases the associated risk and requires the developer to know from before or learn about the library. be intelligent enough to differentiate between "who wrote the code", "who copied the code" and "who indented the code". It is difficult to differentiate between the complexity in the implementation and the intrinsic complexity of the problem. Perhaps a comparison can be made with an equivalent open source counterpart if there is, or for each submodule separately. If there is no such tool, is there no merit in having such a tool? Or do you believe in "I do work, I do not measure"? It takes time after all. Perhaps the project manager should do this estimation continuously, say, weekly. Are there any standards? Yes, standardization is difficult because every project has a different goal, but difficult does not mean it is not useful.

  • IIS Express only utilizes 13% of i7 Quad Core

    - by John Nevermore
    Since one of my scripts got incredibly complex, i was benchmarking the performance of moving some javascript processing logic to the server side in my ASP.NET MVC 4 application. According to taskmgr.exe, IIS Express only utilizes 13% of my i7. I decided to throw in 3 parallel tasks calculating the fibonacci sequence up to 50 and the IIS express still wouldn't utilize more than 13% of my cpu. Is there anything i can do, so that the application utilizes the full cpu, as it would in a real server ?

  • Advantages of Thread pooling in embedded systems

    - by Microkernel
    I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing. Scalability in systems like ucos-2 where there is limit on number of threads. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up). Can set limit on the max system load. Please suggest if I am missing anything.

  • JSON: Jackson stream parser - is it really worth it?

    - by synic
    I'm making pretty heavy use of JSON parsing in an app I'm writing. Most of what I have done is already implemented using Android's built in JSONObject library (is it json-lib?). JSONObject appears to create instances of absolutely everything in the JSON string... even if I don't end up using all of them. My app currently runs pretty well, even on a G1. My question is this: are the speed and memory benefits from using a stream parser like Jackson worth all the trouble? By trouble, I mean this: As far as I can tell, there are three downsides to using Jackson instead of the built in library: Dependency on an external library. This makes your .apk bigger in the end. Not a huge deal. Your app is more fragile. Since the parsing is not done automatically, it is more vulnerable to changes in the JSON text that it's parsing. I'm extremely worried that malformed JSON will result in infinite loops (as pull parsing requires a lot of while loops). Writing code to parse JSON via a stream parser is ugly and tedious.
