kandi X-RAY | coyote Summary
Coyote is a .NET library and tool designed to help ensure that your code is free of concurrency bugs. It gives you the ability to reliably unit test the concurrency and other sources of nondeterminism (such as message re-orderings, timeouts and failures) in your C# code. In the heart of Coyote is a scheduler that takes control (via binary rewriting) of your program's execution during testing and is able to systematically explore the concurrency and nondeterminism to find safety and liveness bugs. The awesome thing is that once Coyote finds a bug it gives you the ability to fully reproduce it as many times as you want, making debugging and fixing the issue much easier.

QUESTION
I am runnng Apache TomEE 9.0.0-M7 with Jakarta EE 9.1 Web Profile. When I run the application using a JTA datasource configuration, the code runs, however when I change to a RESOURCE_LOCAL configuration, the code fails with the exception below. The SQL in the query runs on the JTA configuration.
Please assist.
...ANSWER
Answered 2022-Feb-17 at 18:53By default you are running on an EE container, so it is using a JTA datasource.
If you really want to use RESOURCE_LOCAL, you should check this link on the TomEE documentation, i.e. you define a non-jta datasource in the container (via resources.xml or tomee.xml) and reference it via in the persistente.xml
You can find some information regarding the configuration of a datasource on the TomEE website.

QUESTION
This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.
I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.
As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.
I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...
If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.
...ANSWER
Answered 2022-Jan-12 at 01:03You can shuffle the shortQuizPrompts
array before starting the quiz. Array shuffle details can be found in this answer.
QUESTION
GOAL
I'm relatively new to Unity and I want my character to be able to run and jump at the same time causing the character to go up diagonally.
PROBLEM
However after making some adjustments to give the character some acceleration, the jump seems to clear all existing velocity, meaning the character goes up and then to the side instead of both at the same time:
(I apologise if its a bit hard to see)
CODE
This is my character movement script:
ANSWER
Answered 2022-Jan-09 at 23:05This is happening because you're setting the velocity of your rigidbody directly with rb.velocity = Vector2.up * jumpHeight
. So that will wipe all existing velocity.
If you want to just add a force to the velocity rather than replacing it entirely, you can do that with methods like Rigidbody2D.AddForce.

...ANSWER
Answered 2021-Dec-01 at 11:45You are using same model for getting data from API as well as storing it in DB which is not good practice. It is always better to segregate API and DB models.
However, you can perhaps fix your issue by adding following annotation on your class:

QUESTION
My application is a sprint boot application that uses log4j2 and runs in a Wildfly server. After the zero day attak, we upgraded to the latest log4j2 version(2.16). But after the log4j upgrade, my application stops working once in a while. And when I looked at the threaddumps, I found that there is a deadlock created by log4j. Here is my log4j configuration. It was working fine before the upgrade.
...ANSWER
Answered 2021-Dec-23 at 16:03Found my answer in this thread https://developer.jboss.org/thread/241453. It is a log4j/jboss configuration issue. The fix is to either exclude jboss logging subsystem from jboss deployment configuration or get rid of the console appender. Thanks to Ralph Goers from Log4J team for guiding me towards the jboss thread.
I have closed the issue that I raised to https://issues.apache.org/jira/browse/LOG4J2-3274. The code snippet that I shared in this question was from log4j-1.2 compatibility adapter which doesn't has any impact in my code because I am already using the latest api version.
