Just discovered switching branches is done using the update dialog (VCS -&gt; Update Project, ⌘T), where I can select any branch, tag or revision I want.



For noobs like me that checked the &quot;don&#39;t show this again&quot; box in the beginning, and don&#39;t have the subversion update dialog prompting anymore, try this:

1. Use the command menu &quot;Version Control&quot; -&gt; Show Changes View
2. In this view, go to tab &quot;Subversion Working Copies Information&quot;
3. Here you should find a &quot;Configure Branches&quot; link were you should be able to switch trunk &amp; branches

If I may say, this seems quite complex, if anyone has better, I would be glad to hear :-)

Just use the &quot;Subversion&quot; -&gt; &quot;Update Directory...&quot; with options.
In case the &quot;Update options&quot; dialog is turned off, here is how one can move it back:

 1. Go to: &quot;Settings&quot; -&gt; &quot;Version Control&quot; -&gt; &quot;Confirmation&quot;
 2. Check the box &quot;Display options dialog ...&quot; for &quot;Update&quot;



If like me you hit &quot;configure branches&quot;, and then chose the path of the branch you want - this is wrong! when in &quot;configure branches&quot; you need to select the path one level up from there

hopefully this helps someone like me...

I would like to know if there are any applications like fiddler but for mac OS X, as I need to debug some requests from web applications in Mac OS X. I used to do it with fiddler on Windows and would love to have this tool available on Mac as well. 

Are there any HTTP/HTTPS interception tools like Fiddler for mac OS X?

Before I look through my generic data structure for a value&#39;s index, I&#39;d like to see if it is even an instance of the type `this` has been parametrized to.

But Eclipse complains when I do this:

	@Override
	public int indexOf(Object arg0) {
		if (!(arg0 instanceof E)) {
			return -1;
		}


This is the error message:

&gt; Cannot perform instanceof check against type parameter E. Use instead its erasure Object since generic type information will be erased at runtime

What is the better way to do it?

What is the concept of switching branches in IntelliJ?
I must be either blind or an idiot...

I would assume there&#39;d be a &quot;switch to copy&quot; option or something like that, but there is none...

EDIT for clarification: my prev IDE had a simple &quot;switch to copy&quot; option, which updated all files being different from current branch/trunk.
IntelliJ seems to have a completely different approach to this, which I just do not seem to understand. The help is not very useful either.

Helpful keywords, links or hints are very much appreciated. Thanks.

What&#39;s the most idiomatic way in Java to verify that a cast from `long` to `int` does not lose any information?

This is my current implementation:

    public static int safeLongToInt(long l) {
        int i = (int)l;
        if ((long)i != l) {
            throw new IllegalArgumentException(l + &quot; cannot be cast to int without changing its value.&quot;);
        }
        return i;
    }

.war vs .ear file

I have a friend who&#39;s just getting into .NET development after developing in Java for ages and, after looking at some of his code I notice that he&#39;s doing the following quite often:

    IDictionary&lt;string, MyClass&gt; dictionary = new Dictionary&lt;string, MyClass&gt;();

He&#39;s declaring dictionary as the Interface rather than the Class. Typically I would do the following:

    Dictionary&lt;string, MyClass&gt; dictionary = new Dictionary&lt;string, MyClass&gt;();

I&#39;d only use the IDictionary interface when it&#39;s needed (say, for example to pass the dictionary to a method that accepts an IDictionary interface).

My question is: are there any merits to his way of doing things? Is this a common practice in Java?

I am getting the following error on execution of a multi-threading program

    java.lang.OutOfMemoryError: Java heap space

The above error occured in one of the threads.

1. Upto my knowledge, Heap space is occupied by instance variables only. If this is correct, then why this error occurred after running fine for sometime as space for instance variables are alloted at the time of object creation.

2. Is there any way to increase the heap space?

3. What changes should I made to my program so that It will grab less heap space?

I have a PHP project set up in Eclipse with SVN support. Now, Eclipse adds its project files .buildpath and .project to the project and Subclipse wants to add it to the repository.

Now I could just use svn:ignore to let SVN ignore the files, but that&#39;s not an option for various reasons. So, is there a way to make Eclipse and Subclipse ignore the files (which it should anyway)?

I am trying to simulate a problem we have with a particular domain ID which has issues accessing a subversion repository. Towards this, I tried a `svn checkout` with the 
option `--username domain\problematic_ID` on another windows machine. But I am not able to reproduce the problem as the checkout still succeeds using my own ID. This led me to wonder if SVN caches user authentication data in more than one place and if so where. 

I have cleared the auth directory in the application data area, changed the options in the config file to disable caching of user auth data - but to no avail. The system does not even prompt me for the new user name and password, but simply checks out with the old ID.(I know it is the old ID in use by looking through the SVN logs). I am obviously missing something here -- but what? :-(  

Does anyone know? 

The subversion client version I use is 1.4.6(r28521)

Is it because I need to add some environment variable? Or can&#39;t TortoiseSVN be used from the command line?

I&#39;ve recently started working on various C# projects in Visual Studio as part of a plan for a large scale system that will be used to replace our current system that&#39;s built from a cobbling-together of various programs and scripts written in C and Perl.  The projects I&#39;m now working on have reached critical mass for being committed to subversion.  I was wondering what should and should not be committed to the repository for Visual Studio projects.  I know that it&#39;s going to generate various files that are just build-artifacts and don&#39;t really need to be committed, and I was wondering if anybody had any advice for properly using SVN with Visual Studio.  At the moment, I&#39;m using an SVN 1.6 server with Visual Studio 2010 beta.  Any advice, opinions are welcome.

How do I mark a method as obsolete or deprecated using C#?

How to mark a method as obsolete or deprecated?

I often have to design XML schemas for different XML-bases import routines. It is clear that XML schemas will evolve over time or they could contain bugs to be fixed, so it is important to capture the schema&#39;s version and to have some mechanism to bind against a specific version.

Currently I have two scenarios:

 1. The bug is found within the schema and all schema instances must comply with the fixed version.

 2. The schema upgraded and should be considered as preferable but an old one should be also supported.

Finally I came up with storing version information within the namespace of schema:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/River.xsd&quot;

When fixing a bug I fix it in the same namespace but if I&#39;m about to upgrade a schema then I need to create a new namespace but with upgrade month added:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/01/River.xsd&quot;

And if I have more than one upgrade in a month then just append a day too:

    targetNamespace=&quot;http://schemas.company.com/Geodesy/2010/01/17/River.xsd&quot;

Do you know any better approach?

What are the best practices for versioning XML schemas?

I had a look at https://stackoverflow.com/questions/389169/best-practices-for-api-versioning, but am not quite convinced of the answer, so I am question the versioning part again with a more specific example. I am having two URIs (one with versioning as part of the URI and one without):

    http://xxxx/v1/user/123    -&gt; favored solution in discussed thread
    http://xxxx/user/123             

I am having my doubts whether the first link expresses the idea of REST. I find `http://xxxx/v1/user/123` confusing as it suggests that there will be a higher api-version someday like `http://xxxx/v2/user/123`. But this does not make sense in REST terms, the api version itself is HTTP 1.0 or 1.1, which is already sent inside the HTTP request. This REST resource centric view differs very from other api-interfaces like SOAP or Java-interfaces (where it is common to have api-versions in qualified names).


At REST the only thing where versioning makes sense is the representation of that resource (e.g. new fields are added or removed). This versioning belongs to the part of content-negotiation like:

    http://xxx/user/123 + HTTP &#39;Accept&#39; Header -&gt; Content negotation through header
    http://xxx/user/123?v=1                    -&gt; for perma-links/hyperlinks


One could also argue that such version content-negotiation could be part of the URI inside the path, but I find it counter-intuitive, because you could end-up with different URIs for the same resource and have to maintain redirects at some point.

To sum-up: In REST URIs there is no api-versioning, only versioning of the resource&#39;s representation. Representation version-info belongs to content-negotiation (as queryParam or HTTP &#39;Accept&#39;).

What do you think? In which things would you disagree/agree?


REST api versioning (only version the representation, not the resource itself)

I&#39;ve started playing with Git and have come across the terms &quot;upstream&quot; and &quot;downstream&quot;.  I&#39;ve seen these before but never understood them fully.  What do these terms mean in the context of SCMs ([Software Configuration Management][1] tools) and source code?

I&#39;m just swapping from eclipse to IntelliJ, and I can&#39;t find this particular feature.

Is it possible to set up Intellij to generate javadoc for methods and classes, automatically, with @author and @since date? I had this feature in Eclipse. 

I know that the files have templates and also I can manually semi-automatically add javadoc to selected method/class. But I want the generation to be automatic for every generated method/class/enum/interface/field etc. 

This is useful for e.g. &quot;extract method&quot;, &quot;override/implement&quot;, &quot;create getter/setter&quot; etc. This would save hundreds of manual actions.

I&#39;m using IntelliJ Idea 9.0 BETA Community Edition, #IC-90.96.

I really like IntelliJ IDEA&#39;s &quot;Move statement&quot; shortcut (&lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;&amp;uarr;&lt;/kbd&gt;/&lt;kbd&gt;&amp;darr;&lt;/kbd&gt;). However -- I am not sure if this is a bug releated to ActionScript editing only -- move statement is not always what I want and sometimes it is not correct when editing AS code.

So I just want to move a block of lines up/down. The Eclipse shortcut is &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;&amp;uarr;&lt;/kbd&gt;/&lt;kbd&gt;&amp;darr;&lt;/kbd&gt; and does not move statement-wise. Is there an equivalent in IntelliJ IDEA?

Git pull a certain branch from GitHub

I have an old branch, which I would like to delete. However, before doing so, I want to check that all commits made to this branch were at some point merged into some other branch. Thus, I&#39;d like to see all commits made to my current branch which have not been applied to any other branch [or, if this is not possible without some scripting, how does one see all commits in one branch which have not been applied to another given branch?].



Using Git, show all commits that are in one branch, but not the other(s)

I have a local Git repository called &#39;skeleton&#39; that I use for storing project skeletons. It has a few branches, for different kinds of projects:

    casey@agave [~/Projects/skeleton] git branch
    * master
      rails
      c
      c++

If I want to check out the master branch for a new project, I can do

    casey@agave [~/Projects] git clone skeleton new
    Initialized empty Git repository in /Users/casey/Projects/new/.git/

and everything is how I want it. Specifically, the new master branch points to the skeleton master branch, and I can push and pull to move around changes to the basic project setup.

What doesn&#39;t work, however, is if I want to clone another branch. I can&#39;t get it so that I only pull the branch I want, for instance the `rails` branch, and then the new repository has a `master` branch that pushes to and pulls from the skeleton repository&#39;s `rails` branch, by default.

Is there a good way to go about doing this? Or, maybe this isn&#39;t the way that Git wants me to structure things, and I&#39;m certainly open to that. Perhaps I should have multiple repositories, with the Ruby on Rails skeleton repository tracking the master skeleton repository? And any individual project cloning the Ruby on Rails skeleton repository.

How do I clone a single branch in Git?
