In Idea 17eap: 

`sout`: Prints 

    System.out.println();

`soutm`:  Prints current class and method names to System.out

    System.out.println(&quot;$CLASS_NAME$.$METHOD_NAME$&quot;);

`soutp`: Prints method parameter names and values to System.out

    System.out.println($FORMAT$);

`soutv`: Prints a value to System.out

    System.out.println(&quot;$EXPR_COPY$ = &quot; + $EXPR$);

Yeah, you can do it. Just open Settings -&gt; Live Templates. Create new one with `syso` as abbreviation and `System.out.println($END$);` as Template text. 

If you want to know all the shortcut in intellij hit &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;J&lt;/kbd&gt;. This shows all the shortcuts. For `System.out.println()` type `sout` and press &lt;kbd&gt;Tab&lt;/kbd&gt;.

Open up Settings (By default is Alt + Ctrl + S) and search for Live Templates. In the upper part there&#39;s an option that says &quot;By default expand with TAB&quot; (TAB is the default), choose &quot;Custom&quot; and then hit &quot;change&quot; and add the keymap &quot;ctrl+spacebar&quot; to the option &quot;Expand Live Template/Emmet Abbreviation&quot;.

Now you can hit ctrl + spacebar and expand the live templates. Now, to change it to &quot;syso&quot; instead of &quot;sout&quot;, in the Live Templates option, theres a list of tons of options checked, go to &quot;other&quot; and expand it, there you wil find &quot;sout&quot;, just rename it to &quot;syso&quot; and hit aply.

Hope this can help you.

On MAC you can do `sout + return` or `⌘+j` (cmd+j) opens live template suggestions, enter `sout` to choose `System.out.println();`

Type **`sout`** and press **Tab**, it will generate `System.out.println();`

Type **`sou`** and press **Tab**, It will generate  `System.out.printf(&quot;&quot;);`

If using scala, try [`priv`](https://confluence.jetbrains.com/display/SCA/Live+Templates) + &lt;kbd&gt;tab&lt;/kbd&gt;

I&#39;ve been trying to figure out a good way to load JSON objects in Python.
I send this json data:

    {&#39;http://example.org/about&#39;: {&#39;http://purl.org/dc/terms/title&#39;: [{&#39;type&#39;: &#39;literal&#39;, &#39;value&#39;: &quot;Anna&#39;s Homepage&quot;}]}}

to the backend where it will be received as a string then I used `json.loads(data)` to parse it.

But each time I got the same exception : 

    ValueError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

I googled it but nothing seems to work besides this solution `json.loads(json.dumps(data))` which personally seems for me not that efficient since it accept any kind of data even the ones that are not in json format.

Any suggestions will be much appreciated.



Python/Json:Expecting property name enclosed in double quotes

I am a ruby programmer trying to learn python. I am pretty familiar with pyenv since it is like a copy and paste from rbenv. Pyenv helps allow to have more than one version of python in a system and also to isolate the python without touching sensitive parts of system.

I suppose every python installation comes with pip package. What I still don&#39;t understand is, there are many good python libs out there that suggest to use this virtualenv and anaconda. I can even find a virtualenv plugin for pyenv. 

Now I am getting confused with the purpose of these two pyenv and virtualenv.
worse inside pyenv there is a virtualenv plugin.

My questions are:

 - what is the difference between pyenv and virtualenv?
 - Is there any difference in using  pip command inside both pyenv and virtualenv?
 - what does this pyenv virutalenv do?

Your explanation with example will be highly appreciated.

I know I can print `System.out.println()` with `&quot;sout&quot; + tab`.
Is there a way I can do it with `&quot;Syso&quot; + ctrl + space` like in eclipse?

I developed a microservice using Spring Boot. I was performance testing the  service by stubbing the backend calls. When I looked at the thread count , I see that the maximum number of threads that created to the service is 20 at any point in time even though the number of calls made is much higher. Are there any limitations with respect to number of calls that can be made to a microservice developed using Spring Boot. Please can you guide in what steps I need to follow to troubleshoot / increase the number of connections accepted by the service?

When I hit the database with `PagingAndSortingRepository.findAll(Pageable)` I get `Page&lt;ObjectEntity&gt;`. However, I want to expose DTO&#39;s to the client and not entities. I can create DTO just by injecting entity into it&#39;s constructor, but how do I map the entities in Page object to DTO&#39;s? According to spring documentation, Page provides read-only operations.

Also, Page.map is not possibility, as we don&#39;t have support for java 8. How to create the new Page with mapped objects manually?

I understand how to increase the font size within an editor tab, but I&#39;d like to increase the font size of the main navigation menu and most importantly, the tab titles.  These do not change when I zoom in or out of an editor tab (using Cmd + mouse wheel on OSX). I do not see anything in the preferences menus.

I&#39;m just starting the computer science program at my college, and I&#39;m having some issues with IntelliJ. When I try to run unit tests, I get the message
 
    Process finished with exit code 1
    Class not found: &quot;edu.macalester.comp124.hw0.AreaTest&quot;Empty test suite.
I also see a message entitled &quot;No tests were found&quot; on the left side of my screen. My test code is here:

Using IntelliJ IDEA 15, I get these constant and annoying documentation popups whenever my mouse is anywhere in the code window for a decompiled class (from a 3rd party jar). It will popup docs for whatever variable/method/class/anything happens to be near my mouse. If my mouse is not near any lines of code, it will popup for the current classfile, so basically I can&#39;t browse code unless I move my mouse to another window. 

It only happens with decompiled classes, not my normal code. How do I stop these?

I have 5 environments:

     - local (my development machine)
     - dev
     - qc
     - uat
     - live
     - staging

I want different application properties to be used for each environment, so I have the following properties files each which have a different URL for the datasource:
 

     - application.properties  (containing common properties)
     - application-local.properties
     - application-dev.properties
     - application-qc.properties
     - application-uat.properties
     - application-live.properties

I am using IntelliJ and running my app using bootRun in the Gradle plugin on my local machine.  I will be using deploying the same application war file on all other environments which run Tomcat.

I have tried adding: 

&gt; --spring.profiles.active=local

 to the run configuration under script parameters.

I have tried adding 

&gt; -Dspring.profiles.active=local

 to the run configuration under VM options.

Neither work. I keep seeing the INFO message on startup say: *No active profile set, falling back to default profiles: default*

If I run my app from the windows command line using 

    gradle bootRun

but I first set the environment variable 

    set SPRING_PROFILES_ACTIVE=local

Then everything works.

So my question is, how do I activate my local spring boot profile when running bootRun from IntelliJ ?
