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 change Hostname on Amazon Linux Permanently

-
On Amazon Linux, the process to change the hostname is similar to other Linux distributions. Below are the steps to change the hostname and ensure it remains after a reboot.

1. Edit /etc/sysconfig/network file:

  • /etc/sysconfig/network file is one of the files used to configure networking settings on a Linux system.
  • The changed hostname serves as the network identifier for the system.

sudo vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=your_new_hostname


2. Edit /etc/hostname file:

  • /etc/hostname file defines the system’s hostname and how the server identifies and reports itself on the network.
  • By altering this file, the changed hostname will be applied when the system reboots next.

echo "your_new_hostname" | sudo tee /etc/hostname



3. Edit /etc/hosts file:

  • /etc/hosts file serves the role of mapping IP addresses to hostnames and is referred to before DNS queries are made.
  • For instance, if the 127.0.0.1 address is not mapped to the system's hostname, some systems may be unable to locate themselves, leading to various network-related issues.

sudo vi /etc/hosts

127.0.0.1   your_new_hostname


4. Reboot


sudo reboot


Completing all the above steps will change the hostname permanently on your Amazon Linux instance, and it will remain even after rebooting.

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...
