The pierce selector in Puppeteer

The pierce selector in Puppeteer is an experimental feature that allows you to query shadow DOM elements more easily. Traditional CSS selectors don't pierce through shadow roots because they encapsulate their content to prevent styles and scripts from leaking in or out. The pierce selector solves this by bypassing the shadow DOM boundary and directly selecting elements within shadow trees. How to Use the Pierce Selector in Puppeteer Here’s an example of how to use it effectively: const puppeteer = require ( 'puppeteer' ); ( async ( ) => { const browser = await puppeteer.launch({ headless : false }); const page = await browser.newPage(); // Navigate to a page with shadow DOM await page.goto( 'https://example.com' ); // Select an element inside a shadow DOM using the pierce selector const element = await page.$( 'pierce:#shadow-element-id' ); if (element) { console .log( 'Shadow element found!' ); awai...

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...

언어의 어순과 문화적 특징의 관계를 생각해봅니다.

 "It would be tiresome and very slow as patients recovering from a brain injury affecting the motor system know" 해석은 다음과 같습니다. "운동계에 영향을 미치는 뇌손상에서 회복 중인 환자들이 잘 알고 있듯이, 그 과정은 매우 느리고 또한 피로를 동반하는 것이다." Here are two refined versions in different styles: 1. Formal Academic Version "Such progress would be markedly slow and physically fatiguing, as is well documented among patients recovering from brain injuries that impair the motor system." Uses "markedly slow" and "physically fatiguing" for precision. "As is well documented" signals evidence-based knowledge. "Brain injuries that impair the motor system" is more formal and technical. 2. Plain Everyday Version "It would be really slow and tiring, just like people recovering from a brain injury that affects movement know from experience." Uses "really slow and tiring" for casual tone. Keeps "just like... know from experience...

how to delete all issues on project in sentry, 센트리 이슈 삭제하기

As of now, Sentry doesn't have a direct feature to delete all issues in bulk through the web interface. However, there are a few methods you can use to archive, resolve, or delete issues programmatically or by adjusting project settings: 1. Bulk Archive Issues from the Web Interface Though there is no mass delete option, you can bulk archive or resolve issues, which essentially hides them from active issue lists. Steps: Go to your Sentry project. In the issue list view, select the issues you want to archive or resolve. Use the "Select All" checkbox to select multiple issues. Choose "Resolve" or "Archive" from the bulk action dropdown. However, this doesn't delete the issues permanently; they will be archived or marked as resolved. 2. Adjust Retention Policy (Data Retention Settings) If you're looking to remove older issues, you can adjust the retention policy at the organization level. Sentry allows you to configure how long issue...

PySpark Dataframe from HBase

To filter data from HBase and write it back using PySpark, follow these steps: Read data from HBase into a PySpark DataFrame. Filter the DataFrame using PySpark transformations. Write the filtered DataFrame to your desired format (e.g., HBase, Parquet, CSV, etc.). Below is the complete example covering these tasks. 1. Reading, Filtering, and Writing Data Step-by-Step Code from pyspark.sql import SparkSession from pyspark.sql.functions import col # Step 1: Initialize Spark Session with HBase Configurations spark = SparkSession.builder \ .appName( "HBase-PySpark Read-Write" ) \ .config( "spark.jars" , "/path/to/hbase-client.jar,/path/to/hadoop-common.jar" ) \ .config( "spark.hadoop.hbase.zookeeper.quorum" , "localhost" ) \ .config( "spark.hadoop.hbase.zookeeper.property.clientPort" , "2181" ) \ .getOrCreate() # Step 2: Define the HBase Table Catalog hbase_table = "my_table...
