My Ubuntu Setup: From Barebones to a Productive Dev Environment

When I install a fresh Linux distribution like Ubuntu 24, I'm not just setting up a computer; I'm building a personal workspace. My goal is a clean, reliable, and portable development environment that can be replicated anywhere, from my local machine to a remote VPS.

This isn't just about a list of commands, it's a philosophy of intentionality. Every tool I choose, and every tool I leave behind, is a step toward a more efficient and less cluttered workflow.

This is my journey to a perfect setup, and it all starts with version control.

Python Type Checking Tools: mypy vs. pyright vs. pydantic vs. pandera vs. jaxtyping vs. check_shapes vs. typeguard

Introduction

Are you tired of runtime type errors that could have been caught earlier? Do you work with numerical computing, data science, or ML workflows where shape mismatches cause mysterious bugs?

The Python ecosystem offers a rich variety of type checking tools, from traditional static type checkers to modern runtime validation libraries and specialized shape checkers for scientific computing.

This comprehensive guide explores the landscape of Python type checking tools, helping you choose the right combination for your specific needs.

Git File and Commit Operations: Managing Changes Between States

Introduction

Ever stared at your repo, wondering why a “small” change just won’t commit or push?

GUI tools like GitHub Desktop or VSCode extensions are convenient—but they hide the magic. When things go sideways, or when you need to carefully craft commits, stage parts of files, or undo a “tiny mistake” that isn’t obvious, the GUI often leaves you helpless.

Full CLI Git is where you gain real control. It’s the difference between:

• Clicking buttons blindly and hoping everything works
• Understanding exactly where each change lives (Working Directory, Index, HEAD, Remote) and moving it precisely

Even minor mistakes—like accidentally staging a debug log or overwriting a feature—can snowball into hours of frustration. By mastering the CLI, you can fix problems before they become disasters, cherry-pick changes, or sculpt your commit history like a pro.

Think of this guide as your toolkit: practical commands, clear flows between Git states, and actionable tips to tame your repo—even when the “small” fixes aren’t so small after all.

Comprehensive Guide to SSH: Tunneling, File Transfers, and Key-Based Authentication

SSH (Secure Shell) is a powerful protocol used for secure communication between computers, offering a wide range of functionalities including secure remote access, file transfers, and key-based authentication.

In this guide, we'll cover various aspects of SSH, including:

• Port tunneling for secure access to services like MySQL.
• Secure file transfer using SFTP and SCP.
• SSH agent forwarding and key-based authentication for enhanced security.
• Dynamic port forwarding (SOCKS proxy) for secure browsing.
