The Human and Environmental Cost of Fracking in the United States

The extraction of natural gas by oil and gas companies using the process of hydraulic fracturing or "fracking" in at least 24 states of the United States of America has been a disaster for the human race. They may have lowered natural gas prices domestically by not having to rely on imports, but have contaminated the drinking water supplies of far too many Americans. The primary reason why groundwater has been made unfit for consumption for rural Americans has been the failure to disclose conflicts of interest by members on the committees of environmental regulatory agencies.

Any God-fearing, rational, contributing member of society not driven by greed and not employed in the pursuit of surrogate activities will position themselves on the side of anti-fracking. If not for the sake of personal morals, then at the very least out of respect for our environment and the responsibility we have for preserving it. Disregarding the human cost of fracking is not only disrespectful towards rural Americans directly impacted by having carcinogens mixed in their water supplies but it is also a neglect of the issue of freshwater scarcity.

The US is heavily reliant on imports. The United States' total imports in 2024 were valued at $3.36 trillion, according to the United Nations COMTRADE database on international trade. After China, the US is the largest consumer of fossil fuels. China is also the largest importer of coal and crude oil and the fifth largest importer of natural gas. Countries that have large fossil fuel consumption are typically not able to sustain energy demands through domestic production alone. Using China as an example, it's not unheard of to import fossil fuel. However, bureaucrats would much rather line their pockets by pushing pro-drilling agendas, leaving the average American unable to use their water well.

This innate greed has caused irreversible damage to water wells across the country. Not to mention that the process itself requires anywhere from 1.5 million to 16 million gallons of water per well. Since 2008, the so-called “shale revolution” has helped maintain gas prices in the US—but only at the cost of lasting economic and ecological damage.

Deploying MkDocs with a Virtual Environment to GitHub Pages

Setting up a virtual environment for your MkDocs project is best practice for keeping your dependencies isolated and your deployment clean. This guide walks you through creating a venv, installing dependencies, and deploying your documentation site to GitHub Pages.


Why Use a Virtual Environment?

A virtual environment lets you keep all your Python packages and project dependencies isolated from your system Python installation. This ensures that your MkDocs build is reproducible and avoids version conflicts.


Create a Virtual Environment

First, navigate to your project folder and run:

cd E:\Blog\personal-website
python -m venv venv

This creates a venv folder in your project.
Activate it with:

# On Windows
.\venv\Scripts\Activate

# On macOS/Linux
source venv/bin/activate

You’ll see (venv) appear in your terminal — you’re working inside your isolated environment!


Install MkDocs and Plugins

Inside the venv, install MkDocs, Material for MkDocs, and any plugins you need:

pip install mkdocs mkdocs-material mkdocs-ultralytics-plugin mkdocstrings mkdocs-open-in-new-tab

Optionally, freeze your exact versions:

pip freeze > requirements.txt

This lets you reinstall everything later with:

pip install -r requirements.txt

Build and Preview Your Site Locally

Before deploying, always check that your site builds correctly:

mkdocs build
mkdocs serve

Open http://127.0.0.1:8000 and confirm your site looks as expected.


Push Your Work to GitHub

Make sure your mkdocs.yml and docs/ content are tracked in Git:

git add .
git commit -m "Initial site build with venv"
git push origin main

🔑 Tip: Never push the venv folder — always add venv/ to your .gitignore.


Deploy to GitHub Pages

Deploy directly with:

mkdocs gh-deploy --clean

This: - Builds your site. - Pushes the site/ output to a gh-pages branch. - Publishes to https://<your-username>.github.io/<repo>.


Keep It Clean: .gitignore

Your .gitignore should always exclude:

venv/
__pycache__/
site/
*.pyc

This keeps your repo clean and avoids accidentally pushing build files or Python cache files.


Updating Your Site

When you make edits: 1. Activate the venv:

.\venv\Scripts\Activate
2. Rebuild:
mkdocs build
3. Deploy:
mkdocs gh-deploy --clean


Conclusion

Using a virtual environment ensures your MkDocs project remains isolated and reproducible. Combined with GitHub Pages, you have a simple, robust, and fully automated way to publish your site to the world.

Happy documenting! 🚀

  • Handle Cloudflare Challenges: Seamlessly bypass "wait while your browser is verified" messages.
  • Mitigate CAPTCHA Issues: Reduce interruptions caused by automated bot checks.

Detection Challenges in Web Automation

Websites employ multiple strategies to detect and prevent automated interactions:

  • CAPTCHA Challenges: Validating user authenticity.
  • Cloudflare Browser Verification: Infinite loading screens or token-based checks.
  • Bot Detection Mechanisms: Browser fingerprinting, behavioral analytics, and cookie validation.

These barriers often require advanced techniques to maintain automation workflows.


The Solution: Selenium and Undetected-Chromedriver

The undetected-chromedriver library modifies the default ChromeDriver to emulate human-like behavior and evade detection. When integrated with Selenium, it allows:

  1. Seamless CAPTCHA Bypass: Minimize interruptions by automating responses or avoiding challenges.

  3. Cookie Reuse for Session Preservation: Skip repetitive verifications by reusing authenticated cookies.

Implementation Guide: Setting Up Selenium with Undetected-Chromedriver

Step 1: Install Required Libraries

Install Selenium and undetected-chromedriver:

pip install selenium undetected-chromedriver

Step 2: Initialize the Browser Driver

Set up a Selenium session with UC:

import undetected_chromedriver.v2 as uc

# Initialize the driver
driver = uc.Chrome()

# Navigate to a website
driver.get("https://example.com")
print("Page Title:", driver.title)

# Quit the driver
driver.quit()

Step 3: Handle CAPTCHA and Cloudflare Challenges

  • Use UC to bypass passive bot checks.
  • Extract and reuse cookies to maintain session continuity:
    cookies = driver.get_cookies()
    driver.add_cookie(cookies)
    

Advanced Automation Workflow with Cookies

Step 1: Attempt Standard Automation

Use Selenium with UC to navigate and interact with the website.

Step 2: Use Cookies for Session Continuity

Manually authenticate once, extract cookies, and reuse them for automated sessions:

# Save cookies after manual login
cookies = driver.get_cookies()

# Use cookies in future sessions
for cookie in cookies:
    driver.add_cookie(cookie)
driver.refresh()

Step 3: Fall Back to Manual Assistance

Prompt users to resolve CAPTCHA or login challenges in a separate session and capture the cookies for automation.


Proposed Workflow for Automation

  1. Initial Attempt: Start with Selenium and UC for automation.
  2. Fallback to Cookies: Reuse cookies for continuity if CAPTCHA or Cloudflare challenges arise.
  3. Manual Assistance: Open a browser session for user input, capture cookies, and resume automation.

This iterative process ensures maximum efficiency and minimizes disruptions.


Conclusion

Selenium and undetected-chromedriver provide a powerful toolkit for overcoming automation barriers like CAPTCHA and Cloudflare protections. By leveraging cookies and manual fallbacks, you can create robust workflows that streamline automation processes.

Step 1: Prepare Your Dataset

Dataset Format

Fine-tuning requires a .jsonl dataset where each line is a structured chat interaction. For example:

{"messages": [{"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "What is the capital of France?"}, {"role": "assistant", "content": "The capital of France is Paris."}]}
{"messages": [{"role": "system", "content": "You are a travel expert."}, {"role": "user", "content": "What are the best places to visit in Europe?"}, {"role": "assistant", "content": "Some of the best places to visit in Europe include Paris, Rome, Barcelona, and Amsterdam."}]}

Automate Dataset Preparation

Use the Text to JSONL Converter available at Streamlit to convert .txt files into .jsonl format. Ensure you have at least 10 samples.


Step 2: Fine-Tune GPT-4o-mini

Required Code for Fine-Tuning

Save your stories.jsonl file and run the following Python script to initiate fine-tuning:

from openai import OpenAI
import openai
import os

# Initialize OpenAI client and set API key
openai.api_key = os.getenv("OPENAI_API_KEY")
client = OpenAI()

# Step 1: Upload the training file
response = client.files.create(
    file=open("stories.jsonl", "rb"),  # Replace with the correct path to your JSONL file
    purpose="fine-tune"
)

# Extract the file ID from the response object
training_file_id = response.id
print(f"File uploaded successfully. File ID: {training_file_id}")

# Step 2: Create a fine-tuning job
fine_tune_response = client.fine_tuning.jobs.create(
    training_file=training_file_id,
    model="gpt-4o-mini-2024-07-18"  # Replace with the desired base model
)

# Output the fine-tuning job details
print("Fine-tuning job created successfully:")
print(fine_tune_response)

Explanation of the Code

  1. Initialize OpenAI Client:
  2. The script imports the openai library and initializes the API using your key stored in the OPENAI_API_KEY environment variable.

  3. Upload Training File:

  4. The script uploads your stories.jsonl file to OpenAI's servers for processing.

  5. Create Fine-Tuning Job:

  6. The uploaded file is referenced to create a fine-tuning job for the gpt-4o-mini-2024-07-18 model. Replace this with the desired base model as needed.

function start(client) {
  console.log(`Listening for messages between yourself (${MY_CONTACT_ID}) and ${TARGET_CONTACT_ID}.`);

  const delay = (ms) => new Promise((resolve) => setTimeout(resolve, ms));

  // Function to generate a hash for deduplication
  function generateHash(messageBody) {
    return crypto.createHash('sha256').update(messageBody).digest('hex');
  }

  // Periodically check for new messages in the self-chat
  setInterval(async () => {
    try {
      const messages = await client.getAllMessagesInChat(MY_CONTACT_ID, true, true);
      for (const message of messages) {
        processMessage(client, message, generateHash);
      }
    } catch (err) {
      console.error('Error retrieving self-chat messages:', err);
    }
  }, 2000); // Check every 2 seconds

  // Handle incoming messages
  client.onMessage((message) => processMessage(client, message, generateHash));
}

async function processMessage(client, message, generateHash) {
  const messageHash = generateHash(message.body);

  // Skip if the message has already been processed
  if (processedMessageHashes.has(messageHash)) {
    return;
  }

  // Mark the message as processed
  processedMessageHashes.add(messageHash);

  try {
    if (message.from === MY_CONTACT_ID && message.to === MY_CONTACT_ID) {
      console.log('Message is from you (self-chat).');

      // Translate English to Spanish and send to the target contact
      const translatedToSpanish = await translate(message.body, { to: 'es' });
      console.log(`Translated (English → Spanish): ${translatedToSpanish}`);

      await client.sendText(TARGET_CONTACT_ID, translatedToSpanish);
      console.log(`Sent translated message to ${TARGET_CONTACT_ID}: ${translatedToSpanish}`);
    } else if (message.from === TARGET_CONTACT_ID && !message.isGroupMsg) {
      console.log('Message is from the target contact.');

      // Translate Spanish to English and send to the self-chat
      const translatedToEnglish = await translate(message.body, { to: 'en' });
      console.log(`Translated (Spanish → English): ${translatedToEnglish}`);

      const response = `*Translation (Spanish → English):*\nOriginal: ${message.body}\nTranslated: ${translatedToEnglish}`;
      await client.sendText(MY_CONTACT_ID, response);
      console.log(`Posted translation to yourself: ${MY_CONTACT_ID}`);
    }
  } catch (error) {
    console.error('Error processing message:', error);
    // Remove the hash if processing fails
    processedMessageHashes.delete(messageHash);
  }
}

4. Run the Script

Execute the script using Node.js:

node whatsapp_translator.js

5. What Happens?

  1. Messages you send to yourself (in English) are translated to Spanish and sent to the target contact.
  2. Messages from the target contact (in Spanish) are translated to English and sent to your self-chat.

Debugging Tips

  1. Verify Contact IDs: Ensure MY_CONTACT_ID and TARGET_CONTACT_ID are correctly defined.
  2. Check Logs: Use console.log statements to debug the flow of messages.
  3. Dependency Issues: Reinstall packages with npm install if you encounter errors.

Building an Agentic Web Scraping Pipeline for Crypto and Meme Coins

How to Build an Agentic Web Scraping Pipeline for Crypto and Meme Coins

Agentic web scraping revolutionizes data collection by leveraging advanced scraping tools and LLM-based reasoning to analyze websites for actionable insights. This guide demonstrates how to build a closed-loop pipeline for analyzing popular crypto and meme coin websites to enhance trading strategies.


Websites to Scrape

The following websites will serve as data inputs for the pipeline:

  1. Movement Market
    Facilitates buying and selling meme coins with email and credit card integration.

  2. Raydium
    A decentralized exchange for trading tokens and coins.

  3. Jupiter
    A platform for seamless token swaps.

  4. Rugcheck
    A tool for evaluating meme coins and identifying scams.

  5. Photon Sol
    A browser-based solution for trading low-cap coins.

  6. Cielo Finance
    Offers a copy-trading platform to follow top-performing wallets.


Step 1: Structuring Data for Public Websites

For effective analysis, raw HTML data from these websites must be structured into human-readable Markdown.

Tool: Firecrawl

Use Firecrawl to scrape and format the websites:

Example: Scraping Movement Market

import requests

FIRECRAWL_API = "https://api.firecrawl.com/v1/scrape"
API_KEY = "your_firecrawl_api_key"

def scrape_with_firecrawl(url):
    headers = {"Authorization": f"Bearer {API_KEY}"}
    data = {"url": url, "output": "markdown"}
    response = requests.post(FIRECRAWL_API, json=data, headers=headers)

    if response.status_code == 200:
        return response.json().get("markdown")
    else:
        print(f"Error: {response.status_code} - {response.text}")
        return None

markdown_data = scrape_with_firecrawl("https://movement.market/")
print(markdown_data)

Repeat the process for all listed websites to create structured Markdown files.


Step 2: Analyze Public Data with Reasoning Agents

Once the data is structured, LLMs can be used to analyze trends, extract features, and provide actionable insights.

Example: Analyzing Data with OpenAI API
import openai

openai.api_key = "your_openai_api_key"

def analyze_markdown(markdown_data):
    response = openai.Completion.create(
        model="text-davinci-003",
        prompt=f"Analyze this Markdown data to identify trading opportunities and community sentiment:\n\n{markdown_data}",
        max_tokens=1000
    )
    return response.choices[0].text.strip()

markdown_example = "# Example Markdown\nThis is an example of markdown content for analysis."
analysis = analyze_markdown(markdown_example)
print(analysis)

Step 3: Scraping Private Data with Web Automation

For websites requiring interaction (e.g., logins or dynamic content), use Python's Playwright library with AgentQL for advanced navigation and data extraction.

Example: Scraping Photon Sol with Playwright and AgentQL

Install Playwright and AgentQL:

pip install playwright
playwright install

Write the Python Script:

from playwright.sync_api import sync_playwright

def scrape_photon_sol():
    with sync_playwright() as p:
        browser = p.chromium.launch(headless=True)
        page = browser.new_page()

        # Navigate to Photon Sol
        page.goto("https://photon-sol.tinyastro.io/")

        # Simulate interactions if needed
        page.wait_for_timeout(3000)  # Wait for the page to load completely
        content = page.content()

        print(content)  # Print or save the page content
        browser.close()

scrape_photon_sol()

This approach ensures data can be extracted even from dynamic websites.


Step 4: Automating the Pipeline

Use Python-based automation tools like Apache Airflow to schedule and run the scraping and analysis pipeline.

Example: Airflow Configuration for the Pipeline
from airflow import DAG
from airflow.operators.python_operator import PythonOperator
from datetime import datetime

def scrape():
    # Add scraping logic for all websites here
    print("Scraping data...")

def analyze():
    # Add analysis logic here
    print("Analyzing data...")

with DAG('crypto_pipeline', start_date=datetime(2024, 11, 25), schedule_interval='@daily') as dag:
    scrape_task = PythonOperator(task_id='scrape', python_callable=scrape)
    analyze_task = PythonOperator(task_id='analyze', python_callable=analyze)

    scrape_task >> analyze_task

Insights from Websites

Here's what you can focus on while analyzing the scraped data:

  1. Movement Market: Review ease of use, transaction speed, and user feedback.
  2. Raydium: Analyze liquidity and trading fees for tokens.
  3. Jupiter: Evaluate swap rates and platform efficiency.
  4. Rugcheck: Identify red flags in meme coin projects to avoid scams.
  5. Photon Sol: Assess platform usability for low-cap token trading.
  6. Cielo Finance: Analyze wallet strategies and portfolio performance.

Step 5: Closing the Loop

To maintain a closed-loop pipeline, configure the workflow to automatically re-scrape websites at regular intervals and update analyses with new data. This ensures decisions are based on the latest information.


Conclusion

By integrating structured scraping, advanced analysis, and automation, this agentic pipeline enables real-time insights into the crypto and meme coin ecosystem. Use the steps outlined above to stay ahead in the volatile world of meme coins while minimizing risks and maximizing returns. 🚀

    roscore
    
    Leave this terminal open.

  2. Open a New Terminal and Run turtlesim: Launch a simple simulation:

    rosrun turtlesim turtlesim_node
    

  3. Move the Turtle: Open another terminal and control the turtle using:

    rosrun turtlesim turtle_teleop_key
    
    Use the arrow keys to move the turtle in the simulation.


Step 6: Install Additional ROS Tools

To enhance your ROS setup, install the following:

  1. catkin Tools:

    sudo apt install -y python3-catkin-tools
    

  2. Common ROS Packages:

    sudo apt install -y ros-noetic-rviz ros-noetic-rqt ros-noetic-rqt-common-plugins
    

  3. GPIO and Hardware Libraries (for Pi-specific projects):

    sudo apt install -y wiringpi pigpio
    


Troubleshooting

  • Issue: rosdep not initializing properly.
    Fix: Ensure network connectivity and retry:

    sudo rosdep init
    rosdep update
    

  • Issue: ROS environment variables not set.
    Fix: Manually source the ROS setup file:

    source /opt/ros/noetic/setup.bash
    


Conclusion

Your Raspberry Pi is now configured with ROS 1 Noetic, ready for robotic projects. With this setup, you can develop and deploy various ROS packages, integrate hardware, and experiment with advanced robotic systems.
