Image
This guide will walk you through how to use Poetry to manage dependencies and structure your project in FastAPI . It includes detailed explanations of Poetry's core concepts and commands to help prevent issues that can arise during team collaboration and deployment. 1. What is Poetry? Poetry is a dependency management and packaging tool for Python. It goes beyond simply installing libraries by allowing you to clearly declare the dependencies your project needs and ensuring that all developers on the project have the same library versions. Clarity in Dependency Management : Explicitly manage your project's basic information and required libraries through the pyproject.toml file. Reproducible Builds : By locking all dependency versions in the poetry.lock file, it fundamentally prevents "it works on my machine" problems. Integrated Development Environment : It automatically creates and manages isolated virtual environments for each project and handles mo...

How to extract YouTube to MP3 with yt-dlp

-

yt-dlp

yt-dlp.exe is a powerful command-line program that allows you to download videos and audio from various websites, including YouTube. With this tool, you can easily convert and save YouTube videos as MP3 audio files.

Before you begin, yt-dlp.exe requires a separate program called FFmpeg to convert files to MP3 format. Therefore, you must complete the following two preparatory steps first.

Prerequisites

  1. Download yt-dlp.exe:
  2. Download and Install FFmpeg:
    • Navigate to the official FFmpeg website and download the version compatible with your operating system (Windows).
    • After unzipping the downloaded file, you must either copy the ffmpeg.exe file from the bin folder into the same folder as yt-dlp.exe, or add the path to the folder containing ffmpeg.exe to your system's Path environment variable. For ease of use, it is recommended to place yt-dlp.exe and ffmpeg.exe in the same folder.

How to Download MP3s

Once the prerequisites are met, you can run Command Prompt (CMD) or PowerShell to use the following commands.

  1. Open Command Prompt: Press Win + R to open the Run window, then type cmd and press Enter to launch the Command Prompt.
  2. Navigate to the yt-dlp.exe folder: Use the cd command to move to the folder where your yt-dlp.exe file is located. For example, if the file is in the D:\Downloads folder, you would type:
cd D:\Downloads
  1. Basic MP3 Download Command:
    The most basic command format is as follows. The -x option means to extract audio only, and --audio-format mp3 specifies the audio format as MP3.
yt-dlp.exe -x --audio-format mp3 [YouTube Video URL]

Example:

yt-dlp.exe -x --audio-format mp3 https://www.youtube.com/watch?v=dQw4w9WgXcQ

Useful Additional Options

You can add several useful options for a better-quality result.

  • Specify Audio Quality (--audio-quality): You can set the audio quality, where 0 represents the highest quality. (The default is 5).
yt-dlp.exe -x --audio-format mp3 --audio-quality 0 [YouTube Video URL]
  • Embed Thumbnail (--embed-thumbnail): This allows you to embed the video's thumbnail as album art in the MP3 file.
yt-dlp.exe -x --audio-format mp3 --embed-thumbnail [YouTube Video URL]
  • Combine All Options: You can combine the options above to download an MP3 file with the best audio quality and an embedded thumbnail.
yt-dlp.exe -x --audio-format mp3 --audio-quality 0 --embed-thumbnail [YouTube Video URL]
  • Specify Output Filename (-o): You can set a custom name format for the downloaded file. For example, to use the video's title and ID in the filename, you would write:
yt-dlp.exe -x --audio-format mp3 -o "%(title)s - %(id)s.%(ext)s" [YouTube Video URL]

By using yt-dlp.exe and ffmpeg.exe together in this way, you can easily save your favorite YouTube videos as high-quality MP3 audio files.

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-

Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
