가속도 & 속도

F = ma 에서

가속도(( a ))는 속도(( v ))의 시간(( t ))에 대한 미분이므로, 수식으로 표현하면 다음과 같습니다.

\[a = \frac{dv}{dt}\]

또한, 속도(( v ))는 위치(( x ))의 시간 미분이므로, 이를 포함하여 가속도를 표현하면

\[a = \frac{d}{dt} \left( \frac{dx}{dt} \right) = \frac{d^2 x}{dt^2}\]

즉, 가속도는 위치의 이阶 미분(두 번째 미분)입니다.

Using the MinIO API via curl

Using the MinIO API via curl is straightforward, as MinIO is compatible with Amazon S3 API, so most commands follow a similar syntax. Here’s a guide on how to use curl with the MinIO API for some common operations like uploading, downloading, and managing objects. Prerequisites Access Key and Secret Key : Obtain your MinIO Access Key and Secret Key. MinIO Endpoint : Know your MinIO server endpoint, e.g., http://localhost:9000 . Bucket : You may need an existing bucket name, or create a new one using the commands below. Authentication Header For requests to work with MinIO, you need to include authentication in the headers. MinIO uses AWS Signature Version 4 for signing requests. Common Examples 1. List Buckets To list all buckets in your MinIO account, use: curl -X GET \ - -url "http://localhost:9000/" \ - H "Authorization: AWS <AccessKey>:<Signature>" 2. Create a Bucket To create a new bucket, use: curl -X PUT \ - -url "htt...

How to change java version on gradle of flutter

To change the Java version used by Gradle in a Flutter project, you need to modify the build.gradle files of your Flutter project. Here's how you can do that: Steps: Locate the build.gradle files: You will find two build.gradle files in your Flutter project: One at the root level: <project_root>/android/build.gradle Another inside the app module: <project_root>/android/app/build.gradle Update the Java version in android/build.gradle : In the root build.gradle file, ensure that the sourceCompatibility and targetCompatibility settings are set to the desired Java version. Open <project_root>/android/build.gradle Look for the compileOptions block (or create it if it's not present). Update the Java version like this: allprojects { repositories { google() mavenCentral() } } subprojects { afterEvaluate { project -> if ( project .hasProperty( "android" )) { android { ...

Kafka consumer in a Spring Boot application using a scheduled task

Here’s how to develop a Kafka consumer in a Spring Boot application using a scheduled task for consuming messages. This approach uses @Scheduled to poll Kafka messages at fixed intervals. Step 1: Add Maven Dependencies Add the required dependencies for Spring Kafka and Scheduling in your pom.xml : < dependency > < groupId > org.springframework.kafka </ groupId > < artifactId > spring-kafka </ artifactId > </ dependency > < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter </ artifactId > </ dependency > Step 2: Configure Kafka Consumer in application.yml spring: kafka: bootstrap-servers: localhost: 9092 consumer: group-id: schedule-consumer-group key-deserializer: org .apache .kafka .common .serialization .StringDeserializer value-deserializer: org .apache .kafka .common .serialization .StringDeserialize...
