• In which document do file specifications belong?

  - by Andrew

  In which document would a file specification belong? Perhaps this file is used as an input to a third-party system. Would it belong in its own document? Or would it be better to put it in the functional or design spec? Or somewhere else? When I say file specification, I mean a description of what format the file is (CSV, fixed width, etc), columns, data types, etc. Also, where should you document how the file is generated? i.e. business rules/algorithms which are used to generate the file.

• Controlling new features in Spring/Apache tomcat

  - by HeretoLearn

  Is there a good way to manage roll out of new software in Spring/Tomcat configuration. The problem I am trying to address is being able to rollback newly deployed software provided there are no hard dependencies on other moving pieces. For example changed the guts of an algorithm and now want to deploy the new software with the new change off by default and then turning it on on one of the web servers. An obvious way is to build a session object which has a map of key-value pairs(property,bool) which is populated from a db on a session startup and then the value is persisted for that session. This is so that if the value is reverted back existing sessions which started with the original value retain the original value and giving application consistency. Is there a more obvious inbuilt mechanism to do this?

• Stupid automatic assembly copy problem in Visual Studio 2008 - WTH am I doing wrong?

  - by Dave

  My lazier side has apparently gotten the best of me. When I started to develop with .NET under VS2008 recently, I was very happy to see that all of the dependencies automagically got copied to my application's bin/debug folder upon compilation. This is fantastic. I never even bothered to look into how / why this is done. Yesterday, I decided to make another plugin very similar to an existing one, so I literally copied the folder and all of project files, then renamed the folder and manually edited the project files and file references. I also changed the assembly's GUID. Everything builds fine, but this particular assembly is never copied into my application's bin/debug folder. It is marked as a dependency of my app as well. What did I miss here?

• How do I get stdout into mstest output when running in new app domain?

  - by btlog

  I have been working on test framework, which creates a new app domain to run the tests in. The primary reason being the dll's that we are testing has some horrible code that relies on the dll being located in the app domain path. (No I can't change this code.) The problem that I am having is that my test team is writing a bunch of functional tests in mstest and one of the loggers, that writes to Console.Out, does not have any of the log information captured in the trx output. When running the code through a console app all of the log information is output fine. So do the other loggers that have been implemented. My thought is that mstest is setting its own TextWriter to Console.Out, but the new app doamin has it's own TextWriter for Console.Out as the new app domain has it's own set of statics. I appreciate your ideas.

• How to generate JPA 2.0 metamodel?

  - by yamsha

  In the spirit of type safety associated with the CriteriaQuery JPA 2.0 also has an API to support Metamodel representation of entities. Is anyone aware of a fully functional implementation of this API (to generate the Metamodel... as opposed to creating the metamodel classes manually)? It would be awesome if someone also knows the steps for setting this up in Eclipse (I assume it's as simple as setting up an annotation processor, but you never know). EDIT: Just stumbled across Hibernate JPA 2 Metamodel Generator . But the issue remains since I can't find any download links for the jar

• Should we use Nexus or Artifactory for a Maven Repo?

  - by John Stauffer

  We are using Maven for a large build process ( 100 modules). We have been storing our external dependencies in source control, and using that to update a local repo. However, we are ready to graduate to a local repo that can cache central so that we don't have to proactively download all 3rd parties (but we can still have a local repo to pull from). In addition we want to publish our internal build artifacts from a nightly build so that developers don't have to build the world. We are considering Nexus and Artifactory. What are the reasons for preferring one over the other? Are there others we should be considering?

• Which is the 'correct' way to do this (if statement)

  - by frinkz

  I've got plenty of these lying around, and I'm wondering if I'm going to face any trouble - or performance problems. I have method A: MyClass monkey; ... if(monkey != null) { ... } Or method B: boolean hasMonkey; //This is set to TRUE when monkey is not null MyClass monkey; ... if(hasMonkey) { ... } On a functional level, they both do the same thing. Right now, I'm using method A. Is that a bad way of doing things? Which is going to perform better?

• OpenGL Mapping Textures to a Grid Stored Inside Vertex Array

  - by Matthew Hoggan

  I am writing a test to verify something. This is not production code, just verification code. So I would appreciate it if the specific question was answered. I have code that uses indices and vertices to draw a set of triangles in the shape of a grid. All the vertices are drawn using glDrawElements(). Now for each vertex I will set its corresponding Texture Coordinates to 0 or 1 for each set of triangles that form a square in the grid. Basically I want to draw a collage of random textures in each one of the "squares" (consisting of two triangles). I can do this using the glBegin() and glEnd() method calls inside a for loop using the fixed functional pipeline, but I would like to know how to do this using Vertex Arrays.

• How to get and modify a property value through a custom Attribute?

  - by David G

  I want to create a custom attribute that can be used on a property like: [TrimInputString] public string FirstName { get; set; } that will be functional equivalent of private string _firstName public string FirstName { set { _firstName = value.Trim(); } get { return _firstName; } } So basically every time property is set the value will be trimmed. How do I get the value parsed, modify that value and then set the property with the new value all from within the attribute? [AttributeUsage(AttributeTargets.Property)] public class TrimInputAttribute : Attribute { public TrimInputAttribute() { //not sure how to get and modify the property here } }

• How to find dynamically loaded modules (the static ones) programatically in windows

  - by Ryan Rohrer

  I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

• requireJS : How to structure Javascript for an entire site?

  - by pagewil

  I have 3000+ lines of javascript that I need to get into a sensible/maintainable structure. I have chosen to use requireJS as it has been recommend to me by a few people. I have a bunch of variables that are used throughout the application and need to be available everywhere. I also have a bunch of functions that need to be available everywhere. Apart from these two dependencies most of the code can be divided off into their own modules. I am having trouble understanding how to manage my main variables so that if one module of code makes changes to the variables the rest of the JS modules will see that change. I think I need to see a few examples that demonstrate how requireJS is intended to work on a larger scale that the examples in the documentation. If anyone is an experienced requireJS user I would love the hear your tips!

• Overview look of header inclusions

  - by Ylisar

  When a project grows it becomes hard to get an overview of header inclusion. I've noticed our object files have grown rather large and so I'm thinking there's a lot to be won by rearranging dependencies. This is where the problem begin, I know of no convenient way to actually get an overview on what headers actually get included for a specific source file. There's the possibility of outputting the pre-processed source files, that however creates huge files with loads of irrelevant information. I'm thinking there must be a tool for this, but I can't seem to find any. I'm on windows, so in case anyone know of a good tool / way to actually do this for windows I'd be eternally grateful.

• VS 2008, is there a way to search properties like the old vb6/EVB? CTRL+SHIFT?

  - by Davery

  I really miss the CTRL+SHIFT+CHAR searching of a property in VS 2008 that older IDE's had... typing CTRL+SHIFT+T got you to "tabindex" then Tag when pressed again. They dropped it in VS 2002 I believe, and the closest I could find to restoring any functionality like it was acorn's property window filter, which isn't exactly functional. Does anyone know of a way to get this functionality back? I hate having to browse through 30-40 properties in design mode, when a CTRL+SHIFT+T would get me right to text. Thanks!

• Specifiy classpath for maven

  - by Zombies

  Quite new to maven here so let me explain first what I am trying to do: We have certain JAR files which will not be added to the repo. This is because they are specific to Oracle ADF and are already placed on our application server. There is only 1 version to be used for all apps at anyone time. In order to compile though, we need to have these on the class path. There are a LOT of these JARS, so if we were to upgrade to a newer version of ADF, we would have to go into every application and redefine some pretty redundant dependencies. So again, my goal is to just add these JARs to the classpath, since we will control what version is actually used elsewhere. So basically, I want to just add every JAR in a given directory to maven's classpath for when it compiles. And without putting any of these JAR files in a repository. And of course, these JARs are not to be packaged into any EAR/WAR.

• How do you extend python with C++?

  - by superjoe30

  I've successfully extended python with C, thanks to this handy skeleton module. But I can't find one for C++, and I have circular dependency trouble when trying to fix the errors that C++ gives when I compile this skeleton module. How do you extend Python with C++? I'd rather not depend on Boost (or SWIP or other libraries) if I don't have to. Dependencies are a pain in the butt. Best case scenario, I find a skeleton file that already compiles with C++.

• Secrets of delivering .NET size large products?

  - by Joan Venge

  In software companies I have seen it's really hard to work on very large products where everything depends on everything else. For instance Microsoft works on C#, F#, .NET, WPF, Visual Studio where these things are interconnected. I don't know how many people are involved, but if it's in 100s, how do they keep in sync with everything, so they design and implement features without conflicting with other dependencies and future plans of other products? I am wondering that if MS is able to do this, they must have a very good system. Any guidelines or secrets for MS or non-MS very large software product delivering?

• Description format for an embedded structure

  - by praetorian20

  Hi, I have a C structure that allow users to configure options in an embedded system. Currently the GUI we use for this is custom written for every different version of this configuration structure. What I'd like for is to be able to describe the structure members in some format that can be read by the client configuration application, making it universal across all of our systems. I've experimented with describing the structure in XML and having the client read the file; this works in most cases except those where some of the fields have inter-dependencies. So the format that I use needs to have a way to specify these; for instance, member A must always be less than or equal to half of member B. Thanks in advance for your thoughts and suggestions.

• Constructors + Dependency Injection

  - by Sunny

  If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

• Would dropping X altogether hurt ?

  - by Xavier Maillard

  Hi, I live in the linux terminal all the time under my slackware GNU/linux system (an EeePC). By default, GNU Emacs won't start if It can't find several Xorg libraries. Assuming I will never use X software at all, would it make sense for me to drop all this Xorg stuff and compile emacs again ? Are you aware of anything that could get me into troubles or making GNU Emacs not working at all ? Are there any advantage for me to keep all these dependencies ? I am asking since as said, my main box is an eeepc with little storage and I am dangerously hitting the limits ;-) Regards

• Best environment to port C/C++ code from Linux to Windows.

  - by Simone Margaritelli

  I'd like to make a big project of mine buildable on Windows platforms. The project itself it's written in C/C++ following POSIX standards, with some library dependencies such as libxml2, libcurl and so on. I'm more a Linux developer rather than a Windows developer, so i have no idea of which compiler suite i should use to port the code. Which one offers more compatibility with gcc 4.4.3 i'm using right now? My project needs flex and bison, is there any "ready to use" environment to port such projects to windows platforms? Thanks.

• How to add types from external assembly to toolbox control? (WPF)

  - by Louis Rhys

  I am trying to do something like this in my WPF application: ToolboxControl ctrl = new ToolboxControl(); Assembly assembly = Assembly.LoadFile(file); var category = new ToolboxCategory(assembly.GetName().Name); foreach (Type t in assembly.GetTypes()) { var wrapper = new ToolboxItemWrapper(t, t.Name); category.Add(wrapper); } ctrl.Categories.Add(category); i.e. adding ToolboxItemWrappers for each type found in an assembly. However the last line throws the following exception (see image) All dependencies of the external assembly are also referenced in the main (WPF) application. So what's wrong here and how to fix it?

• How to reference/link another project in grails workspace without using jar files?

  - by Ivan Alagenchev

  I have a Grails website that references a java core application. I have been successful in adding a .jar dependency to that project; however the java project is in the same workspace as my grails project and I would ultimately like to reference that project directly. I don't want to deal with the added step of creating a new jar file every time that there is a modification to the java project, cleaning and updating my dependencies. I added the java project to my grails' project "Java Build Path" and at first everything seemed to work fine, but when I run grailscompile, the compiler fails to resolve all imports that point to the java project. I am using Spring Source Toolsuite as my IDE.

• How do I write a Guice Provider that doesn't explicitly create objects?

  - by ripper234

  Say I have a ClassWithManyDependencies. I want to write a Guice Provider for this class, in order to create a fresh instance of the class several times in my program (another class will depend on this Provider and use it at several points to create new instances). One way to achieve this is by having the Provider depend on all the dependencies of ClassWithManyDependencies. This is quite ugly. Is there a better way to achieve this? Note - I certainly don't want the Provider to depend on the injector. Another option I considered is having ClassWithManyDependencies and ClassWithManyDependenciesProvider extend the same base class, but it's butt ugly.

• 3rd party applications API / Framework Q for PHP user site

  - by Ryan

  So we are defining out functional requirements for a user content site and would like to enable: 1) 3rd party developers to develop applications that users can use on their profile 2) Enable users to export content to other sites meaning share their photos on the net. So we were told we need to use APIs for this & it's merely changing data permissions. Is that the only thing we need? Is there a framekwrok we need to build out, or what is the process functioanlly to define out to make these happen? Platform is being built on MySQL and Cake php.
