-
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...

FFmpeg] How to Convert MKV (MP4, AVI) to MP3 Using FFmpeg on Windows 11

-

I've installed FFmpeg on your Windows 11 laptop and added the FFmpeg directory to my system PATH so I can execute the ffmpeg command from any directory.

1. Create "convert_mkv_to_mp3.bat" in the directory where FFmpeg is installed.


@echo off for %%f in (*.mkv *.mp4 *.avi) do (     ffmpeg -i "%%f" -vn -ab 192k "%%~nf.mp3" )
pause

  • for %%f in (*.mkv *.mp4 *.avi) do (
    • This for loop iterates over all files in the current directory with the specified extensions: .mkv, .mp4, and .avi.
    • %%f: each video file found during the iteration.
  • ffmpeg -i "%%f" -vn -ab 192k "%%~nf.mp3"
    • -i: "%%f" specifies the input video file.
    • -vn: ignore the video stream, extracting only the audio.
    • -ab 192k: sets the audio bitrate to 192 kbps.
    • %%~nf.mp3: output MP3 file and %%~nf extracts the filename.

2. Run the convert_mkv_to_mp3.bat

Navigate to the directory containing video files. Open a Command Prompt window in that directory and run:

If you're a frequent user of SecureCRT , backing up your session settings and restoring them later is crucial—especially when migrating to a new PC or recovering from a crash. In this guide, you’ll learn how to manually back up and restore SecureCRT settings on Windows , ensuring you never lose your configurations again. Does SecureCRT Have a Built-in Export/Import Feature? Yes, SecureCRT provides built-in export and import features in the Tools menu. However, these features may not capture all configuration details such as: Backup scripts Custom login scripts Certain session-specific files Therefore, if you want to completely clone your SecureCRT environment—including every session and customization—the safest option is to manually back up the entire Config folder. What Is the SecureCRT Config Folder? SecureCRT stores your personal settings (sessions, host keys, global options, etc.) in a folder located at: C:\Users\<Your username>\AppData\Roaming\VanDyke\Config Th...

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

-
Image
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...
