Most likely this is the block edit mode. Try pressing &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;A&lt;/kbd&gt;.

Just so to provide solution for MAC again-

I have an app setup where each user belongs to a company, and that company has a subdomain (I am using basecamp style subdomains). The problem that I am facing is that rails is creating multiple cookies (one for lvh.me and another for subdomain.lvh.me) which is causing quite a few breaks in my application(such as flash messages being persistent though out all requests once signed in).

I have this in my /cofig/initilizers/session_store.rb file:

    AppName::Application.config.session_store :cookie_store, key: &#39;_application_devise_session&#39;, domain: :all

The domain: :all seems to be the standard answer I found on Google, but that doesn&#39;t seem to be working for me. Any help is appreciated!

I need to set the height of an **imageview** as **matchparent** programatically.if it is a fixed height i know how to set.

but how can i set it as matchparent?  


**EDIT:**

actually height of the parent layout is dynamic.so i need to make the height of the imageview as the height of parent.

I just started working on a Spring-data, Hibernate, MySQL, JPA project. I  switched to spring-data so that I wouldn&#39;t have to worry about creating queries by hand.

I noticed that the use of `@Transactional` isn&#39;t required when you&#39;re using spring-data since I also tried my queries without the annotation.

Is there a specific reason why I should/shouldn&#39;t be using the `@Transactional` annotation?

Works:

    @Transactional
    public List listStudentsBySchool(long id) {
        return repository.findByClasses_School_Id(id);
    }

Also works:

    public List listStudentsBySchool(long id) {
        return repository.findByClasses_School_Id(id);
    }

Thanks in advance!

What is the advantage of using Condition interface/implementations over the conventional wait notify mechanism? Here I quote the comments written by Doug Lea:

&gt;Condition factors out the Object monitor methods (wait, notify and notifyAll) into distinct objects to give the effect of having multiple wait-sets per object, by combining them with the use of arbitrary Lock implementations. Where a Lock replaces the use of synchronized methods and statements, a Condition replaces the use of the Object monitor methods. 

I see this is a more Object Oriented way of implementing wait/notify mechanism. But is there a sound advantage over the former? 

Condition vs wait notify mechanism

I am using:

    driver.manage().timeouts().implicitlyWait(180, TimeUnit.SECONDS);

But it still fails continuously for the below element 

		driver.findElement(By.id(&quot;name&quot;)).clear();
		driver.findElement(By.id(&quot;name&quot;)).sendKeys(&quot;Create_title_01&quot;);

I have added wait code:

    for (int second = 0;; second++) {
			if (second &gt;= 120) fail(&quot;timeout&quot;);
			try { if (isElementPresent(By.id(&quot;name&quot;))) break; } catch (Exception e) {}
			Thread.sleep(1000);
		}

Shouldn&#39;t implicit wait take care of waiting till an element is found?
Also would it be better if I use Explicit wait instead of the code I have added that has `Thread.sleep()`?

&gt; [Why use getters and setters?](https://stackoverflow.com/questions/1568091/why-use-getters-and-setters)

&lt;!-- End of automatically inserted text --&gt;

I have read books on Java, saying that it is good to create setters and getters for variables such as `x` and `y`.  For example:

    public int getX(){
        return x;
    }

    public void setX(int x){
        this.x = x;
    }

But what is the difference from that and

    ...(shape.x)...   // Basically getX()

and

    shape.x = 90;    // Basically setX()

If setters and getters are better, what practical problems would arise?

How to search for a string in the complete eclipse workspace?

I am programming the host side of a host-accelerator system. The host runs on the PC under Ubuntu Linux and communicates with the embedded hardware via a USB connection. The communication is performed by copying memory chunks to and from the embedded hardware&#39;s memory.

On the board&#39;s memory there is a memory region which I use as a mailbox where I write and read the data. The mailbox is defined as a structure and I use the same definition to allocate a mirror mailbox in my host space.

I used this technique successfully in the past so now I copied the host Eclipse project to my current project&#39;s workspace, and made the appropriate name changes. The strange thing is that when building the host project I now get the following message:

&gt; Building target: fft2d_host  
&gt; Invoking: GCC C Linker  
&gt;  gcc -L/opt/adapteva/esdk/tools/host/x86_64/lib -o &quot;fft2d_host&quot;  ./src/fft2d_host.o   -le_host -lrt  
&gt;
&gt; ./src/fft2d_host.o: In function `main&#39;:  
&gt;
&gt; **fft2d_host.c:(.text+0x280): relocation truncated to fit: R_X86_64_PC32 against symbol `Mailbox&#39; defined in COMMON section in ./src/fft2d_host.o**

What does this error mean and why it won&#39;t build on the current project, while it is OK with the older project?

I researched a bit but most of the issues were related to DataNucleus when working on Google App Engine. But I am not using anything remotely related to Google App Engine. I am doing a small project with Servlet 3.0 on JBOSS 6. I am using Hibernate 4.1.2 for ORM and RESTEasy to expose a web service. I created a util file that has a main() method that basically drops and re-creates the schema. I run the main() methos when I need a clean database for testing purposes. It worked fine on Tomcat 7 but it stopped working when I moved to JBoss 6.

Any hint or solution would be greatly appreciated.

When you&#39;re editing a Microsoft Office VBA macro or function, you will often move your cursor from a line that you haven&#39;t finished.  For example, to go copy something you want to paste into that line.  But, if that partial line isn&#39;t syntactically valid, the VBA editor interrupts your work by popping up a &quot;Compile error&quot; message that has to be dismissed.

Is there any way to disable the message box?  I find it irritating...

I watched a video from YUIConf 2012 in which Douglas Crockford gives a talk about implementing monads in JavaScript. In this talk he gives a code example that utilizes what he calls &quot;Context Coloring&quot; which throws out the idea of coloring by language syntax and introduces different colors for different levels of scope. Here is the link to that specific part of the video.

http://www.youtube.com/watch?feature=player_embedded&amp;v=dkZFtimgAcM#t=15m58s

**Is this context coloring scheme implemented by any code editor for JavaScript or any language?**

I use Sublime Text and this editor like every other code editor I have come across allows color to be applied to syntax. Im not sure if a plugin could solve this problem or if an editor would have to be designed from the ground up to allow this context coloring scheme.
