  • Is there a way to "freeze" a file in Git?

    - by Suan
    I'm in a situation where I want to open source my project, however there's a single source file that I want to release a "clean" version of, but use a separate version locally. Does git have a feature where I can just commit a file once, and it stops looking for changes on that file from now on? I've tried adding the file to .gitignore, but after the first time when I do a git add -f and git commit on the file, and I proceed to edit it again, git status shows the file as changed. The ideal behavior would be for git to not show this file as changed from now on, even though I've edited it. I'd also be interested in how others have dealt with "scrubbing" their codebases of private code/data before pushing to an open source repo, especially on Git.

  • Canonicalizing XML in Ruby

    - by whazzmaster
    I'm working on a SAML gateway using Ruby/Rails and I'm attempting to write some code that validates the xml digital signature of the incoming SAML response against the x509 cert of the originating service. My problem: the signature depends on a canonicalized version of the XML that is hashed and then signed and I'm having trouble finding a ruby lib/gem that will canonicalize XML per the spec. I found a super old gem on rubyforge that is a mess but I'd be more interested if something like nokogiri supported this kind of functionality (from the nokogiri docs, it doesn't). I've googled extensively but thought I'd ask around here to see if anyone has any good insights before I go and try to write my own version or rework the existing c14n-r library.

  • installing NUMPY for Mac OSX 10.7. (Lion) for use with Python

    - by user1744871
    I Need to use nltk and numpy with Python. I am a newbie to Python and initially used the python 2.7.3 that came with my mac (currently running OSX 10.7.5). I learned that the apple version of python may not be robust so I downloaded the standard version from python.org. I have downloaded the nltk program for Mac OSX 10.7. This seemed to install fine. I am trying to download and install numpy using the instructions from the scipy website. http://www.scipy.org/Installing_SciPy/Mac_OS_X. I cloned numpy from github but when I tried to build it using the following command $ python setup.py build I received the following error MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory I also tried to build it using the scons command $ python setupscons.py scons --jobs=2 and received the following error /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setupscons.py': [Errno 2] No such file or directory Can anyone think of a possible workaround?

  • tfs : branch moved folder based on label or date

    - by Andy
    I've moved a folder in tfs using the "move" command but now I cannot create branches off the moved folder based on date or label (label was created when source was in the old folder). I can however create a branch based on "latest version". I get an error message "no items match in if I try to branch of a label. I'm guessing the label references files using the old folder before I moved it. I also get no files if I try to "get specific version" by either date or label. I've tried to roll back moving the folder but this gives me errors such as "An unexpected error occured".

  • "remote file operation failed" on Hudson

    - by Aveen
    I am running a Windows slave for Husdon 1.337 (Linux master). When running a project on the Windows node, it fails with the following message: Building remotely on winTestSlave Checking out a fresh workspace because there's no workspace at C:\hudson\***\ejb remote file operation failed It did work yesterday and I have not upgraded Hudson or changed its configurations (or the slave's configurations) in any way. I establish the connection between the slave and the master by running the following command on a cygwim prompt on the slave: java -jar slave.jar -jnlpUrl http://myserver/computer/winTestSlave/slave-agent.jnlp I saw the issue http://issues.hudson-ci.org/browse/HUDSON-5374 and did as instructed in the work-around but that did not work. I also tried with a newer version of slave.jar (version 1.356) but that did not work either. Does anyone please have any idea of how to fix this? I really cannot find more information anywhere else!

  • What's the fastest way to compare two objects in PHP?

    - by johnnietheblack
    Let's say I have an object - a User object in this case - and I'd like to be able to track changes to with a separate class. The User object should not have to change it's behavior in any way for this to happen. Therefore, my separate class creates a "clean" copy of it, stores it somewhere locally, and then later can compare the User object to the original version to see if anything changed during its lifespan. Is there a function, a pattern, or anything that can quickly compare the two versions of the User object? Option 1 Maybe I could serialize each version, and directly compare, or hash them and compare? Option 2 Maybe I should simply create a ReflectionClass, run through each of the properties of the class and see if the two versions have the same property values? Option 3 Maybe there is a simple native function like objects_are_equal($object1,$object2);? What's the fastest way to do this?

  • How do I debug a ASP.NET application

    - by Jim McKintosh
    I have a ASP.NET application I've inherited from the person who did my job previously, when I try to debug the program I get the error below. "A project with an output type of class librart cannot be started directly" I'm familiar with desktop programs but I'm new to working with ASP.NET, the code is easy enough to understand but I can't get my head around how to successfully debug it. PS VS 2008 if that helps. Thanks Jim

  • Win32: How do I get the listbox for a combobox

    - by Adam Tegen
    I'm writing some code and I need to get the window handle of the listbox associated with a combo box. When looking in spy++, it looks like the parent of the listbox is the desktop, not the combo box. How can I programmatically find the listbox window handle? I know I'd be looking for a window class of ComboLBox that belongs to my process, but how do I narrow that down to the specific one I am looking for? Adam

  • Visual Studio 2005 Ignores Preprocessor directives during compile

    - by miked
    We just got a new developer and I'm trying to set him up with Dev Studio 2005 (The version we all use at this office), and we're running into a weird problem that I've never seen before. I have some code that works perfectly on my system, and he can't seem to get it compiled. We've tracked the issue down to his copy of dev studio ignoring the preprocessor directives. For example, in the project properties under C/C++|Preprocessor|Preprocessor Directives, I add DEFINE_ME. Which should translate to a /D"DEFINE_ME" for the compiler. And it does in my development environment, but it doesn't on his. I verified that when he checks out the code from the source repository, that he has the same version of the code I do. And if I look in his Project Properties, all of the directives are there. For some reason they're just not getting passed down to the compiler. Any Ideas?

  • which lightweight SQL Server type could I use on my Dev machine for a C# VS2010 project?

    - by Greg
    Hi, Which lightweight SQL Server type could I use on my Dev machine for a C# VS2010 project? (e.g. sql server express, sql server ce, full version etc). That is, I'm running on a VMWare fusion instance on my MacBook, and just want something to develop against for a C# VS2010 project. I'm planning on having a simple database (not many tables) but will use Entity Framework. I haven't used SQL Server before so a quick pointer re what is the best database admin interface/app to use for the version you recommend (e.g. to create database, tables etc).

  • JSF tags not being rendered as HTML

    - by Toto
    I'm following the Java EE firstcup tutorial using Netbeans and Glassfish. When I execute the JSF web tier I've been instructed to code, the browser gets the same JSF markup coded in the .xhtml file, and the tags are not rendered as HTML tags. I know this by using the view source code in my browser. For example, for this code: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>Page title here</title> </h:head> <h:body> <h2> <h:outputText value="#{bundle.WelcomeMessage}" /> </h2> </h:body> </html> The browser should get something like: <html ...> <head> <title>Page title here</title> </head> <body> <h2> the welcome message goes here </h2> </body> </html> Right? Well, my browser is getting jsf code (the first piece of code above) and not the html code (the second piece of code above). It seems to be a configuration problem in netbeans or glassfish but don't know what. Any ideas? This is my web.xml file: <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/firstcup/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>greetings.xhtml</welcome-file> </welcome-file-list> </web-app> This is my faces-config.xml file: <?xml version='1.0' encoding='UTF-8'?> <!-- =========== FULL CONFIGURATION FILE ================================== --> <faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"> <application> <resource-bundle> <base-name>firstcup.web.WebMessages</base-name> <var>bundle</var> </resource-bundle> <locale-config> <default-locale>en</default-locale> <supported-locale>es</supported-locale> </locale-config> </application> <navigation-rule> <from-view-id>/greetings.xhtml</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/response.xhtml</to-view-id> </navigation-case> </navigation-rule> </faces-config> Moreover: The url I'm entering in the browser is http://localhost:8081/firstcup/ but I've also tried: http://localhost:8081/firstcup/greetings.xhtml I've checked Glassfish logs and there's no information about not being able to load FacesServlet

  • gcc options for fastest code

    - by rwallace
    I'm distributing a C++ program with a makefile for the Unix version, and I'm wondering what compiler options I should use to get the fastest possible code (it falls into the category of programs that can use all the computing power they can get and still come back for more), given that I don't know in advance what hardware, operating system or gcc version the user will have, and I want above all else to make sure it at least works correctly on every major Unix-like operating system. Thus far, I have g++ -O3 -Wno-write-strings, are there any other options I should add? On Windows, the Microsoft compiler has options for things like fast calling convention and link time code generation that are worth using, are there any equivalents on gcc? (I'm assuming it will default to 64-bit on a 64-bit platform, please correct me if that's not the case.)

  • How can I progrommatically change the target framework from 4.0 to 3.5 of a project/solution?

    - by scott
    Edit 3: After more googling it looks like you can't have the TargetFrameworkMoniker property in a .NET 3.5 application. So I guess I should be asking a different question. How do I change the Target framework from 4.0 to 3.5? Unfortunately, I can only find stuff on how to go the other way. or better yet how do i progrommatically set the target framework version of a project to something other than 4.0? Original question: I just switched to vs2010. I have an application that uses .net 3.5. It loads plugins which are generated by a different app. The plugins are using .net 4 and there for cannot be loaded. I'm using EnvDTE.Project to create a project and set the settings. I can't find what setting needs to be set for this. Edit 1: I'm generating code for about 50 solutions. When I made the switch from vs2005 to vs2010 the projects in those solutions are defaulting to .NET Framework 4.0. So I need to set the .NET Framework to 3.5 when I am generating the code for these solutions. Edit 2: After a lot of googling I found this. so then I tried this: loProp = vsGetProperty("TargetFrameworkMoniker"); vsSetValue(loProp, ".NETFramework,Version=v3.5"); the definitions for those two methods are below. as far as I can tell they do the same this as project.Properties.Item("TargetFrameworkMoniker").Value = ".NETFramework,Version=v4.0,Profile=Client"; I start getting an Property Unavailable Exception later in the code. When I remove the new lines everything works except the projects target framework is still 4.0. The code generators target framework is 3.5 so I can't use the FrameworkName class like shown in the second example in that link. here is vsGetProperty protected Property vsGetProperty(string aProperty) { bool lbDone = false; int liCount = 0; Property loProp; while (!lbDone && liCount < pMaxRetries) { try { loProp = pProject.Properties.Item(aProperty); lbDone = true; return loProp; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } return null; } and vsSetValue protected void vsSetValue(Property aProperty, string aValue) { bool lbDone = false; int liCount = 0; while (!lbDone && liCount < pMaxRetries) { try { aProperty.Value = aValue; lbDone = true; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } }

  • Allowing developer-specific settings in VS2008 projects

    - by Xavier Nodet
    Is it possible to combine the following properties, and if so, how? Store in our version control system some Visual Studio 2008 native C++ project files for the developers in our team that use this IDE. Allow some of those developers to tweak their projects (e.g. using debug version of third-party libraries instead of the usual ones). Make sure these modifications are done in files that are not versioned. In other words, I would like to allow developers to tweak some settings in their projects without risking that these changes are committed. An 'optional VSPROP' file approach seems doomed to fail, as VS2008 refuses to load projects that refer to non-existent VSPROP files... Any other suggestion? Is this possible with VS2010?

  • How to change the assemblyIdentity of a program

    I want to hide the tool I used to create an .exe file. I am not doing anything illegal, I just want to protect my intellectual property from being copied.

"This application has failed to start because its side-by-side configuration is incorrect." How can I solve this?

  • wxPython TreeCtrl without showing root while still showing arrows

    - by None
    I am making a python tree visualizer using wxPython. It would be used like so: show_tree([ 'A node with no children', ('A node with children', 'A child node', ('A child node with children', 'Another child')) ]) It worked fine but it shows a root with a value of "Tree". I made it so that it would create multiple roots but then learned that I wasn't allowed to do that. I reverted to the original code but used changed it from this: self.tree = wx.TreeCtrl(self) to this: self.tree = wx.TreeCtrl(self, style=wx.TR_HIDE_ROOT). It worked but it didn't show the little arrows on the side so you wouldn't know which nodes had children. Is there any way to hide the root node but keep the arrows. Note: I am on a Mac using Python version 2.5 and wxPython version 2.8.4.0.

I have my systemChrome set to standard, and transparent to false, not that they have any relevance to this. Any ideas?

  • [OpenCV] cvFilter2D works very very slow in Ubuntu 9.10 amd64?

    - by Hong
    Hi, has someone tried the cvFilter2D under 64bit linux? Recently when I was trying to port some code to the amd64 version of Ubuntu 9.10, I just found that the cvFilter2D works really slow. The version is Opencv 2.0. The code is as follows: CvMat *mat_src = cvCreateMat(128, 128, CV_32FC1); CvMat *mat_dest = cvCreateMat(128, 128, CV_32FC1); CvMat* mat_kernel = cvCreateMat( 25, 25, CV_32FC1); // initialization ... cvFilter2D( (CvMat*)mat_src, (CvMat*)mat_dest, (CvMat*)mat_kernel, cvPoint( (25-1)/2, (25-1)/2)); // I needs approximately 100ms to finish that... My CPU is Intel 2.4G However, the Opencv 1.1pre only cost me 3ms for the same code...
