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...

Regular expression to remove HTML tags

-

Regular Expression

When you use this regular expression '[^>]*' to find matches in a text, it will identify all HTML tags.

To remove the HTML tags, you can replace the matches with an empty string, effectively eliminating the tags from the text.

:%s/<[^>]*>//g


Break down and explain

This regular expression command breaks down as follows:

Regular expression

Description

:%s

Substitute command to find and replace text in the entire file.

<

This part matches the character < in the text. It looks for the beginning of an HTML tag.

[^>]*

The ^ symbol means "not" in this context. So, [^>] means "any character except >".

The * symbol indicates "zero or more occurrences" of the previous pattern.

Hence, [^>]* matches any number of characters that are not >.

>

This part matches the character > in the text. It looks for the end of an HTML tag.

//

This is the replacement empty string.

g

This 'g' signifies “global”. When it appears at the end of the command, it means that all occurrences of the pattern in each line should be replaced.

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...
