Hello! 안녕하세요! 🥰 I’m Ji

📚 Let’s Start With a Book! I highly recommend The Kubernetes Book by Nigel Poulton. It’s beginner-friendly, concise, and full of real world insights. It’s a great starting point when learning about Kubernetes. 🌍 Where Did the Word Kubernetes Come From? The word Kubernetes (pronounced Q-ber-net-ees) comes from Greek, meaning helmsman or pilot of a ship ⛵. We often use K8s as a shorthand to refer to Kubernetes! This is because there are 8 letters between K and s. ...

In the world of CI/CD, one thing we are all tired of is managing long-lived service account keys. They are hard to rotate.. risky to store, and can lead to serious breaches if leaked! 😿 In this post, I will be showing how to set up GitHub Actions + Google Cloud Workload Identity Federation (WIF) to enable secure, short-lived authentication, with no secrets stored anywhere. 🚫🔑 🚨 The Problem with Static Secrets It is still common to authenticate from GitHub Actions to GCP using service account keys stored as GitHub secrets: ...

Helloo! 👋 How are you? Let’s learn more about cloud security, detection engineering, and scalable policies 🐱🚀 🔍 Detection Engineering with Google SecOps Detection engineering isn’t just about catching threats — it’s about building a smart, scalable detection machine 🛠️. With Google SecOps, detection becomes modular, testable, and highly effective. 🧩 Composite Rules 🐐 Rather than putting every condition into a giant, brittle detection rule, Google SecOps encourages the use of composite rules. Think of them like reusable LEGO bricks 🧱: create small, atomic rules for specific behaviours, then chain them together to form higher-order detections. This lets you mix curated rules with your own custom logic to handle complex attack patterns or environment-specific edge cases. ...

Software delivery has changed a lot over the years! What’s the difference between continuous delivery and continuous deployment? 🤔 And is a feature live just because it’s deployed? 🤨 Let’s look into this together with some modern DevOps 🚀 🌳 Trunk-Based Development Trunk-based development (TBD) is a software development strategy where everyone works from a single branch (trunk) — usually main. It’s fast, lean, and fits in modern delivery practices. 🔧 How it works: Developers commit to main (or short-lived branches that are merged quickly to the main branch) The main branch is always deployable Features are hidden behind flags until they’re ready to go live 🚀 💡 Why it matters: Trunk-based development encourages: ...

When writing code, we often want to know how fast it runs ⏩ and how much memory it uses 💾. This is where time complexity and space complexity comes in! Let’s break these down using Pokémon themed examples! 🔥 ⚡ Big O Notation - The Trainer’s Guide 📖 Big O notation helps us understand how an algorithm scales as the input size grows. Think of it as training a Pokémon: some level up quickly ⚡, while others take longer ⏳! ...
