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...

PYTHONPATH, Python 모듈 환경설정

In Python, an environment variable for a module or Python environment is a way to configure certain settings or provide data paths before running a Python program. Environment variables can be used to: Control Python's runtime behavior (e.g., specifying paths for module search). Pass configuration or sensitive data (like API keys) to Python applications. Set up virtual environments for Python project isolation. Here are some common environment variables related to Python and its modules: 1. PYTHONPATH : This variable defines the search path for modules. It allows you to specify additional directories for Python to look for modules and packages. If you want Python to find your custom modules, you can set this environment variable. Example: export PYTHONPATH= "/path/to/your/module: $PYTHONPATH " In Windows: set PYTHONPATH=C:\ path \ to \your\ module ;%PYTHONPATH% This tells Python to also search for modules in /path/to/your/module . 2. PYTHONHOME : ...

Elasticsearch Ingest API

Elasticsearch Ingest is a feature that allows you to preprocess documents before indexing them. It consists of a pipeline of processors that can manipulate the contents of the documents. One way to test the effectiveness of an Ingest pipeline is to simulate its execution on a sample document. This can be done using the Elasticsearch Ingest API's "simulate" endpoint. To use the "simulate" endpoint, you need to provide a JSON object that represents the document you want to test, and a JSON object that represents the pipeline you want to simulate. Here is an example of how to use the "simulate" endpoint: curl -H 'Content - Type : application/json' -XGET 'localhost : 9200 /_ingest/pipeline/_simulate' -d '{ "pipeline" : { "description" : "Sample pipeline" , "processors" : [ { "set" : { "field" : "foo" , "value" :...

Police uphold the rule of law, even when facing public criticism, because they believe justice must be maintained at all times. 경찰은 항상 정의가 유지되어야 한다고 믿기 때문에, 대중의 비판에 직면하더라도 법치를 지킨다.

Check out the remote branch Once the remote branches are fetched, you can check out the desired branch using git checkout -b and specifying the remote branch. Command: git checkout -b < local -branch- name > origin/<remote-branch- name > Explanation: <local-branch-name> : The name you want to give to your local branch. origin/<remote-branch-name> : Refers to the branch on the remote called origin (which is the default name for the main remote repository) and the branch you want to check out.

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...

티베트-버마어파 와 한어파(중국어파)의 어순 비교

📄 티베트-버마어파 vs. 한어파 어순 비교 구분 티베트-버마어파 (Tibeto-Burman) 한어파 (Sinitic branch) 기본 어순 주어-목적어-동사 (SOV) 주어-동사-목적어 (SVO) 부사 위치 동사 앞에 위치하는 경우가 많음 동사 앞에 위치하는 경우가 일반적 수식어 위치 형용사 및 수식어가 수식 대상 앞에 위치 (일반) 수식어가 수식 대상 앞에 위치 조사/전치사 후치사(postpositions)를 사용하는 경향이 강함 전치사(prepositions)를 사용하는 경향이 강함 문장 예시 (티베트어) ང་ ཟས་ ཟེར་གི་ཡོད་ (나는 밥을 먹는다) (SOV) (중국어) 我吃饭。(나는 밥을 먹는다) (SVO) 1. 기본 어순 차이 티베트-버마어파 는 SOV, 즉 주어(S) 다음 목적어(O), 마지막에 동사(V)가 오는 구조입니다. **한어파(중국어)**는 SVO로, 주어-동사-목적어 순으로 배치됩니다. 이 차이는 문장 구조 전반에 큰 영향을 주며, 두 하위 어파 간 명백한 구분점입니다. 2. 조사와 전치사 사용 티베트-버마어파 언어들은 주로 후치사 를 많이 사용하여, 명사 뒤에 문법적 관계를 나타내는 조사가 붙음. 한어파는 전치사 를 주로 사용하며, 명사 앞에 전치사가 위치함. 예: 티베트어(후치사): ཁྱེད་ལ་ (너에게) 중국어(전치사): 给你 (너에게) 3. 문장 구성 및 부가적 차이 티베트-버마어파는 동사의 부사적 수식어가 동사 앞에 오는 경우가 많으며, 동사 구문이 문장 끝에 집중됨. 중국어는 동사와 목적어가 인접하여 문장 중간에서 동작과 대상이 바로 드러나는 형태를 가짐. 4. 결론 특성 티베트-버마어파 한어파 기본 어순 SOV SVO 조사 사용 방식 후치사 사용 전치사 사용 문장 동사 위치 문장 끝에 위치 문장 중간에 위치 문법적 특징 교착어적 경향 강함 분석어적 ...
