Use [`@Suppress`][1] annotation with argument `&quot;DEPRECATION&quot;`:

    @Suppress(&quot;DEPRECATION&quot;)
    someObject.theDeprecatedFunction()

Instead of a single statement, you can also mark a function, a class or a file (`@file:Suppress(&quot;DEPRECATION&quot;)` in its beginning) with the annotation to suppress all the deprecation warnings issued there.

In IntelliJ IDEA this can also be done through &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;Enter&lt;/kbd&gt; menu with caret placed on code with deprecation warning.


  [1]: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-suppress/

In **Kotlin** 

&gt; @SuppressWarnings

 is changed to 

&gt; @Suppress

 For removing the strike through deprecation warnings you should add,

     @Suppress(&quot;DEPRECATION&quot;)
to remove the warning from the super method.
By adding 

    @Suppress(&quot;OverridingDeprecatedMember&quot;)
The warning of the function will get removed.
So, the complete annotation will be;

    @Suppress(&quot;OverridingDeprecatedMember&quot;, &quot;DEPRECATION&quot;)

As an additional note the deprecation should be written as &quot;DEPRECATION&quot; ( *use capital letters*)

How I can get access to parent&#39;s data variable (limitByNumber) in my child component Post?

I tried to use prop but it doesn&#39;t work.




**Parent:**

    import Post from &#39;./components/Post.vue&#39;;
    
    new Vue ({
        el: &#39;body&#39;,
    
    	components: { Post },
    
    	data: {
    	    limitByNumber: 4
    	}
    });

**Component Post:**

    &lt;template&gt;
        &lt;div class=&quot;Post&quot; v-for=&quot;post in list | limitBy limitByNumber&quot;&gt;
    	&lt;!-- Blog Post --&gt;
        ....
        &lt;/div&gt;
    &lt;/template&gt;

    &lt;!-- script --&gt;    
    &lt;script&gt;
    export default {
        props: [&#39;list&#39;, &#39;limitByNumber&#39;],
        
        created() {
            this.list = JSON.parse(this.list);
        }
    }
    &lt;/script&gt;

I have a table with &gt;1M rows of data and 20+ columns.

Within my table (tableX) I have identified duplicate records (~80k) in one particular column (troubleColumn).

If possible I would like to retain the original table name and remove the duplicate records from my problematic column otherwise I could create a new table (tableXfinal) with the same schema but without the duplicates. 

I am not proficient in SQL or any other programming language so please excuse my ignorance.

I am using a query parameters to set the values needed by the Google Maps API.

The issue is I do not need the `&amp;` sign for the first query parameter.

                                                 @Query(&quot;signature&quot;) String signature);

Retrofit generates:

I&#39;m facing a problem with the new backward compatibility with VectorDrawables.
In the Support Library 23.2 was a new feature for backward compatibility with Android VectorDrawables indroduced. 

I have an ImageView which is a SelectorDrawable assigned to. This Drawable holds several VectorDrawables so I thought I should use app:srcCompat for compatibility. But it does not work on my Galaxy S2 with android 4.1.2.

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;selector xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_fixed_24dp&quot;android:state_activated=&quot;true&quot; android:state_selected=&quot;true&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot; android:state_activated=&quot;true&quot; android:state_selected=&quot;false&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot; android:state_activated=&quot;false&quot; android:state_selected=&quot;true&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_off_24dp&quot; android:state_activated=&quot;false&quot; android:state_selected=&quot;false&quot;&gt;&lt;/item&gt;
        &lt;item android:drawable=&quot;@drawable/ic_gps_not_fixed_24dp&quot;&gt;&lt;/item&gt;
    &lt;/selector&gt;

All drawables are vector xml files.

When using this SelectorDrawable with srcCompat I get this error:

      Caused by: android.content.res.Resources$NotFoundException: File res/drawable/  Caused by: android.content.res.Resources$NotFoundException: File res/drawable/ic_gps_fixed_24dp.xml from drawable resource ID #0x7f0201c1
                                                                               at android.content.res.Resources.loadDrawable(Resources.java:1951)
                                                                               at android.content.res.Resources.getDrawable(Resources.java:672)
                                                                               at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:173)
                                                                               at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:881).xml from drawable resource ID #0x7f0201c1
                                                                                  

using android:src is even worse.

If I use one of the vector drawables with app:srcCompat all works fine. So I guess it&#39;s a problem with the SelectorDrawable and compatibility.

Has anyone had the same problem and found a solution or is it currently not possible to use VectorDrawables in SelectorDrawables prior to Android 5?

The Quick Facts:

 - Compile Target API 23 
 - Support Libraray 23.3.0
 - vectorDrawables.useSupportLibrary = true 
 - Gradle 2.0

Android Selector Drawable with VectorDrawables srcCompat

On my Samsung Galaxy tab 4 (Android 4.4.2, Chrome: 49.0.2623.105) I ran into a situation where the keyCode is always 229. 

I&#39;ve setup a simple test for two situation

    &lt;div contenteditable=&quot;true&quot;&gt;&lt;/div&gt;
    &lt;input&gt;
    &lt;span id=&quot;keycode&quot;&gt;&lt;/span&gt;

script:

    $(&#39;div, input&#39;).on(&#39;keydown&#39;, function (e) {
        $(&#39;#keycode&#39;).html(e.keyCode);
    });
    

[DEMO][1]

Fortunately I can find posts about this, but I couldn&#39;t find one with a working solution. Someone suggested to use `keyup` instead or to use the `textInput` event, but that one is only fired on `blur`.

Now, to top it all, this doesn&#39;t happen with the default stock browser :(

Any help would be appreciated!

UPDATE: If it turns out that this is not possible I can still grab the char before the caret: [post][2]

In git if you checkout a commit directly you get a big fat warning starting with:

    &quot;You are in &#39;detached HEAD&#39; state. You can look around ...&quot;

It&#39;s fine - I intend to be in detached HEAD state. However I am using this in a script and I don&#39;t want this warning in the output logs but I do want the normal output.

My &quot;ugly&quot; workaround now is to run the same command twice, first with -q to hide the warning, and one more time to get the normal output: `HEAD is now at deadbeef... Message` since the warning is only printed once.

Can the warning be disabled so I can avoid workarounds or parsing the output ?

React: validateDOMNesting: #text cannot appear as a child of &lt;tr&gt;

I am using PyCharm (Python 3) to write a Python function which accepts a dictionary as an argument with `attachment={}`.

    def put_object(self, parent_object, connection_name, **data):
        ...

    def put_wall_post(self, message, attachment={}, profile_id=&quot;me&quot;):
        return self.put_object(profile_id, &quot;feed&quot;, message=message, **attachment)

In the IDE, `attachment={}` is colored yellow. Moving the mouse over it shows a warning.

&gt; **Default arguments value is mutable**
&gt; 
&gt; This inspection detects when a mutable value as list or dictionary is
&gt; detected in a default value for an argument.
&gt; 
&gt; Default argument values are evaluated only once at function definition
&gt; time, which means that modifying the default value of the argument
&gt; will affect all subsequent calls of the function.

What does this mean and how can I resolve it?

I see Kotlin has a [`List&lt;out E&gt;`][1] collection and I was wondering about different ways to initialize one. In Java, I could write:

    List&lt;String&gt; geeks = Arrays.asList(&quot;Fowler&quot;, &quot;Beck&quot;, &quot;Evans&quot;);
How can I achieve the same in Kotlin?

How to initialize List&lt;T&gt; in Kotlin?

According to my knowledge:

- `PUT` - update object with its whole representation (replace)
- `PATCH` - update object with given fields only (update)

I&#39;m using Spring to implement a pretty simple HTTP server. When a user wants to update his data he needs to make a HTTP `PATCH` to some endpoint (let&#39;s say: `api/user`). His request body is mapped to a DTO via `@RequestBody`, which looks like this:

    class PatchUserRequest {
        @Email
        @Length(min = 5, max = 50)
        var email: String? = null
    
        @Length(max = 100)
        var name: String? = null
        ...
    }

Then I use an object of this class to update (patch) the user object:

    fun patchWithRequest(userRequest: PatchUserRequest) {
        if (!userRequest.email.isNullOrEmpty()) {
            email = userRequest.email!!
        }
        if (!userRequest.name.isNullOrEmpty()) {
            name = userRequest.name
        }    
        ...
    }

My doubt is: what if a client (web app for example) would like to clear a property? I would ignore such a change. 

**How can I know, if a user wanted to clear a property (he sent me null intentionally) or he just doesn&#39;t want to change it? It will be null in my object in both cases.**

I can see two options here:

- Agree with the client that if he wants to remove a property he should send me an empty string (but what about dates and other non-string types?)
- Stop using DTO mapping and use a simple map, which will let me check if a field was given empty or not given at all. What about request body validation then? I use `@Valid` right now.

How should such cases should be properly handled, in harmony with REST and all good practices?

**EDIT:**

One could say that `PATCH` shouldn&#39;t be used in such an example, and I should use `PUT` to update my User. But what about model changes (e.g. adding a new property)? I would have to version my API (or the user endpoint alone) after every User change. E.g. I would have `api/v1/user` endpoint which accepts `PUT` with an old request body, and `api/v2/user` endpoint which accepts `PUT` with a new request body. I guess it&#39;s not the solution and `PATCH` exists for a reason.

How to do PATCH properly in strongly typed languages based on Spring - example

Say I have a string: `&quot;Test    me&quot;`.

how do I convert it to: `&quot;Test me&quot;`?

I&#39;ve tried using:

    string?.replace(&quot;\\s+&quot;, &quot; &quot;)

but it appears that `\\s` is an illegal escape in Kotlin.
