가속도 & 속도

F = ma 에서

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

a=dvdt

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

a=ddt(dxdt)=d2xdt2

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...

To switch to a specific tag in a Git repository

To switch to a specific tag in a Git repository, you can use the git checkout or git switch command. Here's how you can do it: 1. List Available Tags First, you may want to see a list of all available tags in the repository: git tag 2. Checkout a Specific Tag Once you know the tag you want to switch to, you can use either git checkout or git switch (if you're using a newer version of Git, which recommends git switch for checking out branches). Using git checkout : git checkout <tag- name > Using git switch (recommended for newer versions of Git): git switch -- detach <tag- name > The --detach flag is necessary because tags are not branches; they are just pointers to specific commits. Using --detach makes your HEAD point to the tag without modifying any branch. 3. Verify the Checkout After switching to the tag, verify that you're on the correct commit: git status This will show the tag you're currently on (you'll see somethi...

Comparison of avro plugin

Great question! Both com.github.davidmc24.gradle.plugin.avro and com.commercehub.gradle.plugin.avro are Gradle plugins used for integrating Avro schema compilation into a Java project. However, they have some key differences, and choosing the right one depends on your use case and preferences. Comparison: Aspect com.github.davidmc24.gradle.plugin.avro com.commercehub.gradle.plugin.avro Latest Activity / Maintenance Actively maintained (as of my cutoff date, 2021). CommerceHub's plugin has been largely stable but less actively maintained. Community Usage Growing popularity, newer alternative to CommerceHub's plugin. More widely used for legacy projects. Gradle Plugin Portal Available and regularly updated. Also available, but less frequent updates. Configuration Style Simpler, more modern Kotlin DSL support. Slightly more complex with some legacy design choices. Features Offers a clean interface with support for advanced options (like per-task...
