• What do I need to look out for when I switch compilers from GCC 3.4.2 to a GCC 4.4.2 or to ICC?

  - by Nathan Fellman

  The project I'm working with is compiled with GCC 3.4.2. I'm considering switching to a newer compiler. However, the project is at a stage where we're not making any big changes if the risks aren't well known. What sort of problems can I expect when switching compilers? What benefits does GCC 4.x give over GCC 3.4.2? What benefits does ICC give over it?

• Why are there differing definitions of INT64_MIN? And why do they behave differently?

  - by abelenky

  The stdint.h header at my company reads: #define INT64_MIN -9223372036854775808LL But in some code in my project, a programmer wrote: #undef INT64_MIN #define INT64_MIN (-9223372036854775807LL -1) He then uses this definition in the code. The project compiles with no warnings/errors. When I attempted to remove his definition and use the default one, I got: error: integer constant is so large that it is unsigned The two definitions appear to be equivalent. Why does one compile fine and the other fails?

• Hadoop write directory

  - by FaultyJuggler

  Simple question but reading through documentation and configuration I can't quite seem to figure it out. How do I A) know where hadoop is writing to on the local disk and B) change that For initial testing I setup HDFS on a 20gb linux VM - to it we've added a 500gb networked drive for moving towards prototyping the full system. So now how do I point HDFS at that drive, or do I simply move the home directory/install with some slight change in setup and restart the process?

• Change|Assign parent for the Model instance on Google App Engine Datastore

  - by Vladimir Prudnikov

  Is it possible to change or assign new parent to the Model instance that already in datastore? For example I need something like this task = db.get(db.Key(task_key)) project = db.get(db.Key(project_key)) task.parent = project task.put() but it doesn't works this way because task.parent is built-in method. I was thinking about creating a new Key instance for the task but there is no way to change key as well. Any thoughts?

• Shared Hudson installation - how to enable access to git over ssh?

  - by tputkonen

  We are trying to set up a Hudson server and share it between different projects. Hudson authenticates users against our Windows domain AD, and the project based security matrix makes it easy to manage who can access which projects. Remaining issue is, that most of the projects use git over ssh. Is there a way to make shared Hudson access git so that each project could create their and manage their own jobs without compromising security?

• Why cast null before checking if object is equal to null?

  - by jacerhea

  I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

• Are there any inherent benefits or drawbacks to choosing Google Code vs. SourceForge vs. Codeplex?

  - by kdmurray

  I've got a couple of different projects that I'd like to post up as open source. I've been trying to decide which of the three big open-source project hosting sites makes the most sense, or if I should just host it myself. Are there any inherent drawbacks or benefits to these three? Is there a "best" place to host a project? Do different sites make more sense for different kinds of projects?

• How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

  - by Aaron Digulla

  In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

• Is it possible to use maven only for running selenium plugin?

  - by tputkonen

  Our pom.xml currently contains both the build settings, as well as execution of selenium using selenium-maven-plugin. I would like to split it in to two pom files, one for the build and unit tests and the second one for executing selenium tests. (This way I could first build the project in Hudson, and after successful build execute Selenium tests using another project). Is it possible to configure maven to only execute the selenium-maven-plugin?

• In jQuery, is there any way to only bind a click once?

  - by Chris Henry

  I have an ajax app that will run functions on every interaction. I'd like to be able to run my setup function each time so all my setup code for that function remains encapsulated. However, binding elements more than once means that the handler will run more than once, which is obviously undesirable. Is there an elegant way in jQuery to call bind on an element more than once without the handler being called more than once?
