Currently Elasticsearch offers standard deviation (STDDEV) and variance (VAR) both in population form however there's also the sampling form which depending on the data size, can yield significantly different results.
As it's just a matter of a (somewhat) different formula, it should be straight forward to expand the current implementation [Ex
Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.
If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from peo
The current ParamValidationNaming can only check explicit argument validation (i.e., the method body lists requireNonNull or verifyPositive) but not overloads delegating to those methods thus lacking the explicit argument validation themselves.
I don't think this can be automated, therefore, each base reactive class' source should be manually examined and expanded with the missing `@throw

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
the correct one should be :

你的朋友正在使用键盘输入他的名字 name。偶尔,在键入字符 c 时,按键可能会被长按,而字符可能被输入 1 次或多次。
你将会检查键盘输入的字符 typed。如果它对应的可能是你的朋友的名字(其中一些字符可能被长按),那么就返回 True。
示例 1:
输入:name = "alex", typed = "aaleex"
输出:true
解释:'alex' 中的 'a' 和 'e' 被长按。
示例 2:
输入:name = "saeed", typed = "ssaaedd"
输出:false
解释:'e' 一定需要被键入两次,但在 typed 的输出中不是这样。
示例 3:
输入:name = "leelee", typed = "lleeelee"
输出:true
示例 4:
输入:name = "laiden", typ

There should be a README file for each type of design pattern which should include the following points-
- Description of the design pattern
- Common use cases of that design pattern
- Explanation of the code
Sometimes we only want view a file content quickly and in that cases, on current version of GUI, we need close the tab after do a single click on some node in the tree.
I think that would be nice, if we can have a "preview mode" option. When we do a single click, a tab is opened with the content of the node, but if we click on another node, the content of these tab is replaced by the new one. T

🚀 Feature Proposal
In the Java class RemoteWebDriver within the method:
protected Response execute(String driverCommand, Map<String, ?> parameters)
the execute command is wrapped around logs statements:
log(sessionId, command.getName(), command, When.BEFORE);
response = executor.execute(command);
log(sessionId, command.getName(), command, When.AFTER);
can this be changed

Overview of the feature request
When having entities with many fields, having them in the entity-update.component.ts file could be tedious. Also, when coding side-by-side it will force me to duplicate my code for creating the form, updating the form and for creating the entity from form (those can be big methods).
**Motivation for or Use
[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.
