In the App class of the abstract-factory pattern, there are several methods which seemingly only serve to confuse readers.
Is there a point to having a method that returns a King, from a passed in KingdomFactory?

King getKing(final KingdomFactory factory) {
     return factory.createKing();
   }

I'm new to Spring Boot.
I created an application with https://start.spring.io/, using Gradle, Java 11, Spring Boot 2.2.5.
Reading the reference documentation here and [here](https://docs.spring.io/spring-boot/docs/2.2.5.RELEASE/reference/html/spring-boot-features.html#boot-features-l

The heap.png image in the readme (https://raw.githubusercontent.com/kdn251/interviews/master/images/heap.png) shows a tree that does indeed respect the heap order property. The problem is when you mention the time complexities. In order to have O(log(n)) insert / remove time you also need for your heap to be a complete binary tree. The heap in the picture is not a complete binary tree. I think it

MutableClassToInstanceMap

I think it permits null values but not keys. Eventually we should have nullness annotations that make the clear, but even then, it's nice to document up front, as we do for most other types.

Perhaps the ClassToInstanceMap interface should also be clearer that null keys are forbidden and null values might or might not be.

I'd like to be able to limit the retry count in Authenticator to 3. At the moment it appears to be 20. I don't see anything to do this and didn't get an answer in StackOverflow, so assuming it's not possible at the moment.

• Documentation:

It would be nice if the official documentation explains how to use Retrofit together with co-routines together with the best practices regarding the asynchronous handling of requests. My students need to implement their calls using Retrofit and co-routines (following the tutorials in the Udacity course, but for documentatio

How can i remove data labels from chart ?

使用队列实现栈的下列操作：

push(x) -- 元素 x 入栈
pop() -- 移除栈顶元素
top() -- 获取栈顶元素
empty() -- 返回栈是否为空
注意:

你只能使用队列的基本操作-- 也就是 push to back, peek/pop from front, size, 和 is empty 这些操作是合法的。
你所使用的语言也许不支持队列。 你可以使用 list 或者 deque（双端队列）来模拟一个队列 , 只要是标准的队列操作即可。
你可以假设所有操作都是有效的（例如, 对一个空的栈不会调用 pop 或者 top 操作）。

Change 'left <= right' to 'left < right', can improve efficiency in some cases

It would be helpful to new users who want to communicate with the site administrator or get on a mailing list to include a contact subsection under the README.md file as a subsection.

Many users confuse about no class, no method, expression error.

Arthas should add a verbose/debug option, to print the command arguments and the debug info in command execution.

🐛 Bug Report

using selenium-server-standalone-3.141.59.jar from cli:
java -jar selenium-server-standalone-3.141.59.jar -role node -nodeConfig seleniumNode.json
gives me this error:
`Exception in thread "main" org.openqa.grid.common.exception.GridConfigurationException: Deprecated -nodeConfig file encountered. Please update the file to work with Selenium 3. See https://github.com/Seleniu

What's the ETA for updating the massively outdated documentation?

Please update all documents that are related building CNTK from source with latest CUDA dependencies that are indicated in CNTK.Common.props and CNTK.Cpp.props.
I tried to build from source, but it's a futile effort.

Issue details

Camera.unproject does not return original value

Reproduction steps/code

    public void create() {
        Vector2 tmpvec = new Vector2();
        tmpvec.set(0, 0);

        Stage stage = new Stage(new ScreenViewport());
        stage.stageToScreenCoordinates(tmpvec); // has the correct screen coords;
        stage.screenToStageCoordinates(tmpvec);
        

[REQUIRED] Use case description

Gradle provides both way to write build script - Groovy, and Kotlin.
While both languages are perfectly fine to write typical build logic, they have different APIs in some cases.

To build locally in Kotlin, one should use gradle.extra - ExtraPropertiesExtension, which is not defined in the class definition of Gradle.

// ExtraPropertiesExte
