**How do I discard all git commits that haven&#39;t been pushed and then force git to not commit anything in the data/ directory?**

I&#39;m trying to force overwrite all changes to a project stored on github from my c9.io project.  I accidentally git added some mongodb data files.  I tried to add the data/ directory to .gitignore. I pulled from github to get the updated .gitignore, however when I try and git push, these stubborn files in data/ are still staged for commit.  I also tried git reset, git rebase, git clean and [this](http://www.thisprogrammingthing.com/2013/fixing-the-this-exceeds-githubs-file-size-limit-of-100-mb-error/) where I changed dmpfile.sql to pi/data/node-login.1.

Please help I&#39;ve been at this for hours and I&#39;m really frustrated

I newly wrote a simple chat application, but I didn&#39;t really understand the background of ICE Candidates.

When the peer create a connection they get ICE Candidates and they exchange them and set
them finally to the peerconnection.

So my question is, where do the ICE Candidates come from and how are they used and are they all really used ?

I have noticed that my colleague got less candidates when he executes the application on his machine, what could be the reason for different amount of Candidates ?


What are ICE Candidates and how do the peer connection choose between them?

I&#39;m trying to get tweets using twitter4j library for my java project which uses under the covers `java.net.HttpURLConnection` (as can be seen in stack trace). On my first run I got an error about certificate `sun.security.validator.ValidatorException` and `sun.security.provider.certpath.SunCertPathBuilderException`. Then I added twitter certificate by:

    C:\Program Files\Java\jdk1.7.0_45\jre\lib\security&gt;keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore &quot;C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts&quot;

But without success. Here is the procedure to get tweets:

    public static void main(String[] args) throws TwitterException {
        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true)
            .setOAuthConsumerKey(&quot;myConsumerKey&quot;)
            .setOAuthConsumerSecret(&quot;myConsumerSecret&quot;)
            .setOAuthAccessToken(&quot;myAccessToken&quot;)
            .setOAuthAccessTokenSecret(&quot;myAccessTokenSecret&quot;);
        
        TwitterFactory tf = new TwitterFactory(cb.build());
        Twitter twitter = tf.getInstance();
        
        try {
            Query query = new Query(&quot;iphone&quot;);
            QueryResult result;
            result = twitter.search(query);
            System.out.println(&quot;Total amount of tweets: &quot; + result.getTweets().size());
            List&lt;Status&gt; tweets = result.getTweets();
            
            for (Status tweet : tweets) {
                System.out.println(&quot;@&quot; + tweet.getUser().getScreenName() + &quot; : &quot; + tweet.getText());
            }
        } catch (TwitterException te) {
            te.printStackTrace();
            System.out.println(&quot;Failed to search tweets: &quot; + te.getMessage());
        }

I have an Android project that has been developed entirely within Android Studio (currently version 4.2, gradle version 1.9-all). I want to add functionality from Google Play Services.

The project is unable to resolve `GooglePlayServicesUtil`, and when I enter the import manually (shown below), I get `Cannot resolve symbol &#39;common&#39;`.

    import com.google.android.gms.common.GooglePlayServicesUtil;

Any idea what I need to do to get `GooglePlayServicesUtil` to resolve?

## What I&#39;ve Tried
From the [Google Play Services Setup](http://developer.android.com/google/play-services/setup.html) it looks like I just have to add the `com.google.android.gms:play-services:4.+` dependency to my `build.gradle` file (and resync project files with gradle) to make the SDK available to my project. I do get an &quot;exploded bundle&quot; in `ProjectName/module/build/exploded-bundles`, but that doesn&#39;t seem like it does the trick.

I have Google Play Services, Android Support Repository and Google Repository installed from the SDK Manager already. I&#39;ve also deleted and reinstalled them multiple times :)

Edit:

Might I need to manually add google_play_services as a Project/Global Library? I&#39;ve attempted with no success.

I&#39;m trying to verify that I&#39;m developing against the Platform API with Google Services (if that&#39;s even possible), but I&#39;m not sure that&#39;s the case. Nothing I change seems to do anything.

The External Libraries of my project shows:

* &lt; Android API 19 Platform &gt;
* &lt; 1.7 &gt;
* joda-time-2.3
* support-v4-13.0.0

How do I configure the TCP/IP port listened on by a Spring Boot application, so it does not use the default port of 8080.

How to configure port for a Spring Boot application

I have an object hierarchy that increases in complexity as the inheritance tree deepens. None of these are abstract, hence, all of their instances serve a, more or less sophisticated, purpose.

As the number of parameters is quite high, I would want to use the Builder Pattern to set properties rather than code several constructors. As I need to cater to all permutations, leaf classes in my inheritance tree would have telescoping constructors.

I have browsed for an answer here when I hit some problems during my design. First of, let me give you a simple, shallow example to illustrate the problem.

    public class Rabbit
    {
        public String sex;
        public String name;

        public Rabbit(Builder builder)
        {
            sex = builder.sex;
            name = builder.name;
        }

        public static class Builder
        {
            protected String sex;
            protected String name;

            public Builder() { }

            public Builder sex(String sex)
            {
                this.sex = sex;
                return this;
            }

            public Builder name(String name)
            {
                this.name = name;
                return this;
            }

            public Rabbit build()
            {
                return new Rabbit(this);
            }
        }
    }

    public class Lop extends Rabbit
    {
        public float earLength;
        public String furColour;
        
        public Lop(LopBuilder builder)
        {
            super(builder);
            this.earLength = builder.earLength;
            this.furColour = builder.furColour;
        }

        public static class LopBuilder extends Rabbit.Builder
        {
            protected float earLength;
            protected String furColour;

            public LopBuilder() { }

            public Builder earLength(float length)
            {
                this.earLength = length;
                return this;
            }

            public Builder furColour(String colour)
            {
                this.furColour = colour;
                return this;
            }

            public Lop build()
            {
                return new Lop(this);
            }
        }
    }

Now that we have some code to go on, imaging I want to build a `Lop`:

    Lop lop = new Lop.LopBuilder().furColour(&quot;Gray&quot;).name(&quot;Rabbit&quot;).earLength(4.6f);
This call will not compile as the last chained call cannot be resolved, `Builder` not defining the method `earLength`. So this way requires that all calls be chained in a specific order which is very impractical, especially with a deep hierarchy tree.

Now, during my search for an answer, I came across https://stackoverflow.com/questions/17164375/subclassing-a-java-builder-class which suggests using the [Curiously Recursive Generic Pattern][1]. However, as my hierarchy does not contain an abstract class, this solution will not work for me. But the approach relies on abstraction and polymorphism to function which is why I don&#39;t believe I can adapt it to my needs.

An approach I have currently settled with is to override all methods of the superclass `Builder` in the hierarchy and simply do the following:

    public ConcreteBuilder someOverridenMethod(Object someParameter)
    {
        super(someParameter);
        return this;
    }

With this approach I can assure I am being returned an instance I can issue chain calls on. While this is not as worse as the Telescoping Anti-pattern, it is a close second and I consider it a bit &quot;hacky&quot;.

Is there another solution to my problem that I am not aware of? Preferably a solution consistent with the design pattern. Thank you!

Builder Pattern and Inheritance

I am a relative newcomer to the world of Java enterprise development.  My organization&#39;s Java guru is out on indefinite family leave, and I have been assigned the task of maintaining some of the Java applications he developed.  He setup Eclipse [Kepler SR1] with Maven on my computer before he left, and it appeared to work ok.

Now I&#39;m ready to deploy my first modification and need to run a Maven `install`, but I am having trouble getting it to work - I get the following output on my console:

&gt; [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project mrpapp: Compilation failure&lt;br /&gt;
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

but I definitely *am* running a JDK and not a JRE.  I double-checked my `$JAVA_HOME` (`C:\Program Files (x86)\Java\jdk1.7.0_60`) and it *does* have a `javac.exe` in its `bin` directory.

I am attaching a copy of my `pom.xml` file for your review.  I&#39;m sure there is something in there that is causing the problem, but I am not sure what it might be.  I am using a laptop with Windows 7 64bit, if you need any further platform/environment info I can supply that as well.

Any help will be greatly appreciated.

Unable to start derby database from Netbeans 7.4

I have problem with starting Apache Tomcat 6 from Netbeans IDE 7.4 (on 7.3 version I had the same troubles. Other people mentioned that this problem exist also in other versions, like 8.0 etc). 

What did I do: 

 - remove installed Tomcat 7 (without removing it, I had the same difficulties) 
 - add new server, downloaded from Apache Tomcat website (version apache-tomcat-6.0.39, with other version I had the same problems) 
 - my server location: D:\apache-tomcat-netbeans 
 - system variable CATALINA_HOME: D:\apache-tomcat-netbeans 
 - system variable JAVA HOME: C:\Program Files\Java\jdk1.7.0_51\ 
 - tomcat user: I let netbeans creating new user, called tomcat with password tomcat. When I open {tomcat}\conf\tomcat-users.xml file after adding server, there is info about my user: 

    &lt; user password=&quot;tomcat&quot; roles=&quot;manager,admin&quot; username=&quot;tomcat&quot;/ &gt;

When I now click &quot;start&quot;, I got &quot;**Starting of Tomcat failed**&quot;. 

My suspicions: 

  - I&#39;m working on Windows 7 as administrator, so I think this is not a problem with privileges to files. 
  - Disabling proxy didn&#39;t helps. 
  - Logs: There is only one log file created: localhost.2014-03-06.log and it is totally empty. 
  - Starting Netbeans &quot;as administrator&quot; didn&#39;t helps.
  - From command line everything is all right, I have no problems with starting in normal or debug mode (*catalina.bat jpda start* or *startup.bat*)

I&#39;m trying to run NetBeans under Windows 8.1 on a screen with a high DPI. Windows itself has scaling enabled to 400% and everything else looks just fine.

However, when I start NetBeans, it runs as if there&#39;s no scaling enabled and I just see tiny little letters in the IDE. I did check the properties under which the IDE starts and they do have &quot;Enable scaling for this program&quot; checked.

I could increase font size in the editor and the error log, which would at least enable me to view what I&#39;m typing on the screen, however, all menus, side-bars, panels, etc, remain very small which is very uncomfortable trying to work with. So any idea how I can make NetBeans scale with Windows 8.1? Currently using NetBeans 8.0.

I recently downloaded JDK 1.8.0.0_06 that comes bundled with NetBeans. I then got to find out that my JavaFx project, that I have been developing in Java 1.7 won&#39;t compile in Java 1.8, and so I stepped down my JDK to 1.7. Still I can&#39;t get it to work/ compile. I get this error:

	javac: invalid target release: 1.8
	Usage: javac &lt;options&gt; &lt;source files&gt;

I&#39;m really stuck and would greatly appreciate any help.

Both Google and Stackoverflow have shown me people with similar issues however this error is slightly different in that the IP address is suffixed with an asterisk:&lt;br&gt;&lt;br&gt;

NetBeans 8.0.1 is giving me the following error when trying to start Tomcat.&lt;br&gt;

&#39;127.0.0.1*&#39; is not recognized as an internal or external command,
operable program or batch file.&lt;br&gt;&lt;br&gt;

I&#39;ve got both Tomcat 7.0.56 and Tomcat 8.0.14 installed, they both start OK from the command line (one at a time). I have them added to NetBeans&#39; list of servers as Tomcat 7 and Tomcat 8.&lt;br&gt;&lt;br&gt;

I have a &quot;Hello World&quot; web app which I have configured:&lt;br&gt;
Properties -&gt; Run -&gt; Server: tried both Tomcat 7 and Tomcat 8&lt;br&gt;
Both give the same error.

If I try starting Tomcat using either:&lt;br&gt;
Services -&gt; Servers -&gt; Tomcat 7 -&gt; Start&lt;br&gt;
Services -&gt; Servers -&gt; Tomcat 8 -&gt; Start&lt;br&gt;
I get the same error as when trying to start a web app:&lt;br&gt;&lt;br&gt;

&#39;127.0.0.1*&#39; is not recognized as an internal or external command,
operable program or batch file.&lt;br&gt;

Any ideas ?&lt;br&gt;
Even if it&#39;s only what that asterisk is doing there ?

I know that you can jump from almost all windows in Intellij IDEA to the editor window with &lt;kbd&gt;Esc&lt;/kbd&gt;. In Intellij&#39;s terminal window, this does not work. Does anyone know how to do this with a keyboard shortcut? This would be nice since I can jump from my editor to the terminal with &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;F12&lt;/kbd&gt; but I cannot do it the other way without using my mouse.

I mean like this ones?

Is there any command to select the whole file contents in Emacs? 

For example, &lt;kbd&gt;Control&lt;/kbd&gt;+&lt;kbd&gt;a&lt;/kbd&gt; selects whole contents of a file in Notepad, Notepad++, etc. 

I can select whole contents using the mouse, but it&#39;s inconvenient for large files. I found the basic Emacs commands [here][1] and [here][2], but could not find what I am looking for.

I&#39;m trying to overwrite a getter method for an ActiveRecord model. I have an attribute called `name` in the model `Category`, and I&#39;d like to be able to do something like this:

    def name
      name_trans || name
    end

If `name_trans` attribute is not nil, then return it, else return `name` attribute. How would I do this?

This should then be called normally like this:

    @category.name


How can I overwrite a getter method in an ActiveRecord model?

With this simple class I am getting the compiler *warning* 

&gt; Attempting to modify/access `x` within its own setter/getter

 and when I use it like this:

    var p: point = Point()
    p.x = 12

I get an EXC_BAD_ACCESS. How can I do this without explicit backing ivars?


    class Point {
        
        var x: Int {
            set {
                x = newValue * 2 //Error
            }
            get {
                return x / 2 //Error
            }
        }
        // ...
    }

Property getters and setters

Is there a way to have a private setter for a property in TypeScript?

	class Test
	{
		private _prop: string;
		public get prop() : string
		{
			return this._prop;
		}

		private set prop(val: string)
		{
			//can put breakpoints here
			this._prop = val;
		}
	}

Compiler complains that visibility for getter and setter don&#39;t match. I know I can just set the backing field, but but then I can&#39;t set breakpoints when the value is set.

I though about using an interface to hide the setter, but interfaces can only define a property, not whether it has a getter on setter.

Am I missing something here? There doesn&#39;t seem to be any reason to not allow private setters, the resulting JS doesn&#39;t enforce visibility anyway, and seems better that the current alternatives.

Am I missing something? If not is there a good reason for no private setters?

Private setter typescript?

I have the following class:

    class ReportView: NSView {	
    	var categoriesPerPage = [[Int]]()
    	var numPages: Int = { return categoriesPerPage.count }
    }

Compilation fails with the message:

&gt; Instance member &#39;categoriesPerPage&#39; cannot be used on type
&gt; &#39;ReportView&#39;

 What does this mean? 


Instance member cannot be used on type

I have a doubt about protocols in Swift about the use of **var** and the **keywords { get set }**.

From [Apple documentation][1]:

&gt; If a protocol requires a property to be gettable and settable, that
&gt; property requirement cannot be fulfilled by a constant stored property
&gt; or a read-only computed property. If the protocol only requires a
&gt; property to be gettable, the requirement can be satisfied by any kind
&gt; of property, and it is valid for the property to be also settable if
&gt; this is useful for your own code.
&gt; 
&gt; Property requirements are always declared as variable properties,
&gt; prefixed with the var keyword. Gettable and settable properties are
&gt; indicated by writing { get set } after their type declaration, and
&gt; gettable properties are indicated by writing { get }.

I can&#39;t understand why I can&#39;t use **let**. A **var** in a protocol with only **get** isn&#39;t just a **let**?

Something like this:

    protocol someProtocol 
    {
       var someProperty: String { get }
    }

it would not be just:

    protocol someProtocol 
    {
       let someProperty: String
    }

I&#39;m missing something?
