New Year, New Series: Build your own [BYO]

As the calendar flips to a new year, it’s the perfect time to embrace fresh challenges and embark on exciting journeys. This year, I’m thrilled to announce a brand-new series: Build Your Own. The goal of this series is to dive deep into how common Linux command-line utilities work and recreate them using modern technologies like Java, GraalVM, and Spring Native.

Why This Series?

Linux command-line tools are the unsung heroes of software development and system administration. Utilities like grep, cat, ls, and curl have been around for decades, and they’ve proven to be indispensable in countless workflows. By building these utilities from scratch, we get to:

Understand Their Inner Workings: There’s no better way to learn than by doing. Rebuilding these tools gives us a peek under the hood.
Enhance Problem-Solving Skills: Each utility comes with unique challenges that push us to think critically and creatively.
Leverage Modern Tech: By using Java, GraalVM, and Spring Native, we can reimagine these utilities with better performance and cross-platform capabilities.
Foster Community Learning: Sharing this journey helps others learn, contribute, and grow alongside me.

The Tech Stack

1. Java

Java is a robust and versatile programming language with a rich ecosystem. It’s a perfect choice for this project because it combines simplicity with power, making it ideal for building both small utilities and large-scale applications.

2. GraalVM

GraalVM is a high-performance runtime that extends Java capabilities with native image generation. By using GraalVM, we can compile our utilities into lightweight native binaries, ensuring lightning-fast startup times and reduced resource usage.

3. Spring Native

Spring Native enables the creation of Spring Boot applications as native executables. This allows us to leverage the Spring ecosystem’s productivity while reaping the benefits of native compilation.

What to Expect

In this series, we’ll tackle a variety of CLI utilities, starting simple and progressively increasing in complexity. Here’s a sneak peek at some of the tools we’ll build:

cat: Displaying file contents.
grep: Searching for patterns in files.
wc: Counting words, lines, and characters.
ls: Listing directory contents.
curl: Fetching data from URLs.

For each utility, we’ll cover:

An Overview: What the tool does and its real-world applications.
Implementation: Step-by-step coding walkthroughs using Java, GraalVM, and Spring Native.
Optimization: Techniques to improve performance and usability.
Comparison: How our version stacks up against the original.

Join the Journey

This series is more than just coding; it’s about exploring, learning, and sharing knowledge. Whether you’re a seasoned developer or a curious beginner, I invite you to follow along, experiment with the code, and share your thoughts and improvements.

The first post in this series drops soon, where we’ll recreate the humble yet powerful cat command. Until then, let’s toast to a year of innovation, learning, and growth.

Stay tuned, and happy New Year!
