Tip: you can find any action in the menu &quot;Help&quot; -&gt; &quot;Find Action...&quot;.

This specific action is in the menu &quot;Tools&quot; -&gt; &quot;New Scratch File...&quot;.

Windows/Linux: &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Insert&lt;/kbd&gt;

In Mac the shortcut is: &lt;kbd&gt;Shift&lt;/kbd&gt;&lt;kbd&gt;ctrl&lt;/kbd&gt;&lt;kbd&gt;N&lt;/kbd&gt;

Key map Mac OSX 10.5 : &lt;kbd&gt;Shift&lt;/kbd&gt;&lt;kbd&gt;⌘&lt;/kbd&gt;&lt;kbd&gt;N&lt;/kbd&gt;

I need to normalize a list of values to fit in a probability distribution, i.e. between 0.0 and 1.0.

I understand *how* to normalize, but was curious if Python had a function to automate this.

I&#39;d like to go from:

    raw = [0.07, 0.14, 0.07]  
to  

    normed = [0.25, 0.50, 0.25]

Normalizing a list of numbers in Python

Might be a strange question but indeed I would like to achieve a a bit more coverage on my tests and although I coded against a `JsonProcessingException` I can&#39;t create a payload that generates this exception, maybe because Jackson is quite smart and converts everything to a string, and even for bad strings it goes around the JSON specs. My problem is that Jackson is quite good :)

I basically want a payload that when I run this, it break with `JsonProcessingException`:


    String jsonPayload = objectMapper.writeValueAsString(payload);



I&#39;ve tried some like:

    HashMap&lt;String, String&gt; invalidJSONPayload= new HashMap&lt;&gt;();

    invalidJSONPayload.put(&quot;021&quot;,021);
    invalidJSONPayload.put(&quot;---&quot;,021);
    invalidJSONPayload.put(&quot;~&quot;,021);


I&#39;m not fussed with the type, so feel free to suggest another one. An empty object for example, throws `JsonMappingException` and I already catch that one as well.

Scratch files are mentioned in the release announcement for IntelliJ 14 but it does not mention how to create or use them. Any links to documentation would be extremely helpful. 

**What I Have Already Tried**

I have already performed several web searches for creating scratch files and the only things that have turned up are articles talking about the feature, none of which specify how to actually use the feature.  

I have also tried &quot;File&quot;-&gt;&quot;New...&quot;, but there is no option for scratch files.

I did find some documentation on scratch files in a [PhpStorm plugin](https://plugins.jetbrains.com/plugin/4428?pr=phpStorm), but, despite both being JetbBrains products, that appears to be completely unrelated and none of those shortcuts work.

I just upgraded my Intellij IDEA to version 14, but I have the problem that my cursor in the editor window is acting &quot;different&quot;. It starts of in a sort of protected mode, which looks like the insert mode but it isn&#39;t, where I can&#39;t insert anything. After pressing some keys like &lt;kbd&gt;a&lt;/kbd&gt; it changes back to normal except that sometimes it goes in a selection mode and by that I mean if I hit &lt;kbd&gt;backspace&lt;/kbd&gt; instead of deleting the character as expected it just selects/highlights it. I find this behavior really annoying and I hope one of you can help me.

Additional Information:&lt;br/&gt;

&gt; &gt; Mac OS X 10.10 Yosemite&lt;br/&gt; Intellij 14.0&lt;br/&gt;

Please ask if i can provide any additional information which might be helpful.

Intellij 14 weird editor/cursor behaviour

After updating to `IntellijIdea 14` I have discovered that an excluded folder in my project is now visible.

Webstorm doesn&#39;t recognize one of my .js files as a JavaScript file so I&#39;m losing syntax highlighting and being able to add break points. I&#39;ve looked in the `workspace.xml` file and the file in question seems to have similar settings to other .js files that work correctly.

If I change the name of the file it works ok. So somehow Webstorm is stuck on misinterpreting the type of a file that has this name. Where else can I edit the project?

When a case class has many fields and their names are long, it is often a good idea to write each field in each line like:

    case class Person (
      name: String,
      age: Int
    )


This resembles C/C++ `struct` definition and totally readable even when the case class becomes bigger. But IntelliJ IDEA&#39;s default Scala plugin automatically changes its indentation:

    case class Person (
                        name: String,
                        age: Int
                        )

which looks weird to me, but the [Scala Style Guide](http://docs.scala-lang.org/style/indentation.html) doesn&#39;t mention anything about case class indentation.

I couldn&#39;t find anything in the IDE settings that can change this behaviour. Is there an option to make the auto-indentation work like the way I described above or disable auto-indentation for case classes?


IntelliJ Scala Plugin&#39;s case class indentation is absurd

I have created a simple unit test but IntelliJ is incorrectly highlighting it red. marking it as an error


No beans?

As you can see below it passes the test? So it must be Autowired?

While changing the values of a `widget` in `properties` tab, `AndroidStudio` keeps on throwing `IndexNotReadyException`. But after few minutes while retrying, the error is not occurring.

Details:

* **IDE**: IntelliJ IDEA 14
* **O.S.:**: Windows 7

If I want to navigate to the **declaration** of a method I can choose one of the following approaches:

* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + left click
* right click &gt; Go To &gt; Declaration
* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;B&lt;/kbd&gt;

If I want to navigate to the **implementation** of a method I can choose one of the following approaches:

* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + left click
* right click &gt; Go To &gt; Implementation(s)
* press &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;B&lt;/kbd&gt;

In **Eclipse**, if I press &lt;kbd&gt;Ctrl&lt;/kbd&gt; and the mouse is over a method, a popup appears and I can choose what to do (go to Implementation/Declaration). If I press &quot;left click&quot; ( &lt;kbd&gt;Ctrl&lt;/kbd&gt; is still pressed ) the first option will be chosen.

Is it possible to expand the entire project tree in Intellij? I would like to do this so I can more easily search the structure and jump back and forth between files and folders. 

I know of double shift, and CTRL+SHIFT+N, but that is not what I am after.
