uv - faster pip written in Rust 🦀

Anant Mishra — Mon, 02 Mar 2026 03:23:20 +0000

If you’ve been working with Python for a while, chances are you’ve used pip more times than you can count.

Python packaging has historically been fragmented in pip, virtualenv, poetry, conda ... uv aims to unify much of that experience into one consistent tool.

What Can uv Do?

uv isn’t just a faster pip. It’s more like a unified Python packaging tool.

Tool	What `uv` Does
`pip`	Install packages
`pip-tools`	Compile lock files
`pipx`	Install CLI tools
`virtualenv`	Create and manage environments
`poetry` (partially)	Project + dependency management

Insallation

Visit Astral-uv before running these commands just in-case they have changed them.

MacOS and Linux

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Working with uv

Creating a FastAPI project

There are so many commands integrated with uv that I can’t cover in this article. So instead, let’s build a simple project with a virtual environment, specific python version, project metadata and dependencies all in few commands.

uv init my-app --python 3.12
cd my-app
uv add fastapi uvicorn

What `uv` did ?

uv init my-app --python 3.12

uv init initializes a brand-new Python project and configures it to use a specific Python version (3.12 in this case).

Behind the scenes, it:

📁 Creates the project directory (my-app) (with version-control .git) and generates a pyproject.toml (managing dependendicies)
Sets requires-python = ">=3.12" and depending resoution with locking support.

No manual setup. No boilerplate. No extra tooling.

uv add fastapi uvicorn

On adding the dependencies, it automatically:

📦 Creates a virtual environment (.venv/) if it doesn't already exist and installs the packages inside that environment
Updates pyproject.toml - resolves dependencies and generates a uv.lock file for reproducible installs

Running the app - `uv run`

Updating main.py with

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
    return {"Hello": "World"}

Run it with:

uv run uvicorn main:app --reload

uv run ensures the command executes inside the managed environment — no activation needed.

Learning `uv`

Nothing better than reading their documentation - Astral - UV docs

That’s the beauty of uv - it removes the initial setup and keeps the workflow focused on building, not managing tools, another great tool built with rust 🦀

Hashing Pairs Like a Pro in C++

Anant Mishra — Fri, 20 Oct 2023 03:26:31 +0000

Let's say you are writing a code which include mapping of pairs (let's say coordinates in a grid) in C++.

Problem

If you try to do this directly:

std::unordered_map<std::pair<int, int>, std::string> gridMap;

You’ll get a compiler error. Why?

Because C++ (before C++20) doesn’t know how to hash a std::pair.

Solution: Custom Hash Function 😏

Let's create a pair hash

#include <iostream>
#include <unordered_map>

using namespace std;

struct pair_hash
{
    template <class T1, class T2>
    size_t operator()(const pair<T1, T2> &p) const
    {
        return hash<T1>{}(p.first) ^ (hash<T2>{}(p.second) << 1);
    }
};

int main()
{
    unordered_map<pair<int, int>, string, pair_hash> gridMap;

    gridMap[{0, 0}] = "START";
    gridMap[{1, 2}] = "Bomb 💣";
    gridMap[{2, 3}] = "Treasure 💰";
    gridMap[{5, 5}] = "END";

    for (const auto &[pos, label] : gridMap)
    {
        cout << "(" << pos.first << ", " << pos.second << ") -> " << label << "\n";
    }
}

Output

(5, 5) -> END
(2, 3) -> Treasure 💰
(1, 2) -> Bomb 💣
(0, 0) -> START

Simplify Password Management with the 'pass' Command-Line Password Manager

Anant Mishra — Fri, 30 Jun 2023 01:47:15 +0000

Introduction

In this blog post, we will explore the Pass - command-line password manager, which provides a secure and convenient way to manage your passwords. We will start with the initial setup, including generating a GPG key, and then proceed to cover storing, retrieving, and removing passwords using 'pass'. We will also discuss additional tips and best practices for using 'pass' effectively.

Initial setup

🔑 Generating a GPG Key

The first step to setting up the 'pass' password manager is generating a GPG (GNU Privacy Guard) key. GPG provides encryption and decryption functionality, securing your passwords in the 'pass' password store. To generate a GPG key, use the following command:

$ gpg --gen-key

You will be prompted to enter your name and email address. Additionally, you will be asked to set a passphrase.

Note
This passphrase is crucial as it acts as the master password for all your passwords, so make sure to choose a strong and memorable passphrase.

Copy your GPG Key 6G5E33C8EDF352343243256F23FW23A06C20 from the output

pub ...
6G5E33C8EDF352343243256F23FW23A06C20

🔒 Installing pass

Next, you need to install the 'pass' password manager on your system. The installation process may vary depending on your distribution. Here are a few examples:

sudo dnf install pass # Fedora
sudo apt install pass # Debian/Ubuntu/PopOS!
...

Now your 🔒 + 🔑 are ready, so create a 'password-store'

$ pass init <GPG KEY>
# pass init 6G5E33C8EDF352343243256F23FW23A06C20

a directory .password-store will be created in your HOME, this dir stores all your passwords (that simple it is!)

Storing passwords

Inserting your own password

You want to store your Github password but you have two personal and work accounts, do this

$ pass insert github/personal
Enter password for github/personal: ...
$ pass insert github/work
Enter password for github/work: ...

Checkout .password-store, it'll look like this

📂  .password-store
└── 📂 github
   ├── 🔑 personal.gpg
   └── 🔑 work.gpg

Generating random password

$ pass generate github/personal

A random password will be generated and stored under the specified label.

Retrieving passwords

To retrieve your stored passwords, you will need to provide the passphrase you set during the GPG key generation. Here are two ways to retrieve passwords:

Show password in terminal

$ pass show github/personal
YOUR_PASSWORD

Copy password in clipboard for 45 seconds

$ pass show -c github/personal
Copied github/personal to clipboard. Will clear in 45 seconds.

Removing passwords

$ pass rm github/personal
Are you sure you would like to delete github/personal? [y/N]
removed '/home/USER/.password-store/github/personal.gpg'
