Generate a list of 4-letter Discord usernames by creating all possible 4-letter combinations using letters A-Z (case-insensitive). For each username, determine its availability on Discord by checking against a Discord API or reliable service. Steps: 1. Generate all 4-letter strings using letters A-Z (case-insensitive). 2. For each username, check the availability status on Discord. 3. Collect the usernames along with their availability status, labeled clearly as "available" or "unavailable". 4. If real-time checking is impossible, simulate availability status but clearly indicate this limitation. Constraints: - Only generate usernames valid under Discord username policies. - Avoid excessive API calls to prevent rate limiting; implement caching or limit the number of usernames checked. Output Format: Provide the result as a JSON array where each element is an object with two properties: - "username": a 4-letter string - "availability": either "available" or "unavailable" Format example: ```json [ {"username": "abcd", "availability": "available"}, {"username": "wxyz", "availability": "unavailable"} ] ``` Make sure the output clearly distinguishes availability statuses.

Create a Pine Script strategy for trading that uses the 5-period and 15-period Exponential Moving Averages (EMAs) for scalping. The strategy should generate buy signals when the 5 EMA crosses above the 15 EMA and sell signals when the 5 EMA crosses below the 15 EMA. Include clear entry and exit rules based on these crossovers. Ensure the code is well-commented for clarity and follows Pine Script best practices. # Steps 1. Define the EMA lengths as 5 and 15. 2. Calculate the 5 and 15 period EMAs. 3. Detect crossover events between the 5 EMA and 15 EMA. 4. Generate buy orders when the 5 EMA crosses above the 15 EMA. 5. Generate sell orders when the 5 EMA crosses below the 15 EMA. 6. Implement exits corresponding to the buy and sell signals. 7. Add comments explaining each part of the code. # Output Format Provide the complete Pine Script strategy code enclosed in proper Pine Script syntax, ready to be used on TradingView, with comments for each logical block.

Create a stylish and user-friendly 404 error page using React and Chakra UI.

Generate an R code snippet that unlocks or validates a 5-character code. The code should include input validation to ensure the code consists of exactly 5 characters, and it should demonstrate how to check the code against a predefined list or pattern of valid codes. Provide clear comments explaining each part of the code. # Steps 1. Define a function that accepts a 5-character code as input. 2. Validate the input length to ensure it is exactly 5 characters. 3. Define a list or vector of valid 5-character codes or specify a pattern. 4. Check if the input matches any valid code or the pattern. 5. Return an appropriate message indicating whether the code is valid (unlocked) or invalid. # Output Format Provide a complete, well-commented R script snippet illustrating the unlock code logic. # Examples ```r # Example valid codes valid_codes <- c("ABCDE", "12345", "A1B2C") # Function to unlock code unlock_code <- function(code) { if (nchar(code) != 5) { return("Error: Code must be exactly 5 characters long.") } if (code %in% valid_codes) { return("Code unlocked successfully!") } else { return("Invalid code. Access denied.") } } # Test the function unlock_code("ABCDE") # Should return success message unlock_code("XYZ12") # Should return invalid message ```

Integrate the 404deals API with the SCRAPERNAME scraper using the implementation in 404deals_api.py as a reference. Ensure the following requirements are met: 1. **Filter Deals**: Only send deals to 404deals that already meet the criteria for Discord notifications based on the `DISCOUNT_THRESHOLD` defined in `config.py`. 2. **Add Configuration**: Copy the 404deals API endpoint and token to the scraper's `config.py` file. 3. **Function Implementation**: Implement the `send_deal_to_404deals` function directly in the `notifier.py` file without creating external dependencies. ### Function Requirements: - The function must send the following required fields to the API: `title`, `url`, `old_price`, `new_price`, `discount_percentage`, and `site`. - For optional fields (`EAN`, `image_url`, `availability`), check the Discord embed creation code under the `_create_embed` method to see which fields are already utilized in the product data. Include those in the API call if present. ### Field Checks: - Examine the Discord embed code to determine the availability of `EAN`, `image_url`, and `availability`. For example, if the embed code contains something like `"thumbnail": {"url": product_data["image_url"]}`, you must include `image_url` in the API call. ### Logging and Error Handling: - Follow the existing error handling and logging patterns used throughout the scraper. ### Integration Point: - Add the 404deals API call immediately after sending the Discord notification, specifically for deals that meet the discount threshold. ### Formatting the Site Field: - Use the website's name as the `site` field in `deal_data` formatted to lower case with `.nl` appended (e.g., if the website’s name is Google, use `google.nl`). ### Proxies Configuration: - Update the scraper to read its proxies from the parent directory instead of its current folder. The proxies file is named `proxies.txt` and should be loaded from one level up from the scraper's location.

Generate a secure R code snippet that accepts a 5-digit numeric input as an unlock code. The code should validate the input to ensure it is exactly five digits long and numeric. Implement logic to verify the entered code against a predefined correct 5-digit code. Provide user feedback indicating whether the entered code is correct (unlock successful) or incorrect (unlock failed). Ensure the code is clear, well-commented, and uses best practices for input handling and validation in R.

Create a 5-minute countdown timer displayed on a webpage or application. The timer should count down from 5 minutes to zero, updating every second, and clearly show the remaining time in minutes and seconds (MM:SS format). Include an image that acts as a clickable link; when the user clicks this image, the 5-minute countdown timer should start displaying and begin counting down immediately. Ensure the timer stops automatically at zero and visually indicates that the countdown has completed (e.g., by showing "Time's up!" or similar). # Steps 1. Display an image prominently on the interface. 2. Make this image a clickable element with an associated link or action. 3. When the image is clicked, show the 5-minute countdown timer. 4. Update the timer display every second, showing the remaining time in MM:SS format. 5. When the timer reaches zero, stop the countdown and show a message indicating completion. # Output Format Provide the complete HTML, CSS, and JavaScript code that implements this functionality. The code should be well-structured and commented for clarity. Include placeholder URLs or image sources if necessary. # Notes - The image can be a placeholder or a sample image URL. - The timer should be user-friendly and visually clear. - The solution should work in modern web browsers.
