The Problem: Distributed Transactions in Hotel Booking Let's break down our hotel booking system into its core components: * Reservation Service: Handles room availability and booking * Payment Service: Processes payments * Notification Service: Sends confirmation emails...

TL;DR: Formal Methods = Async Superpowers Formal methods aren't just for academic papers and PhD theses anymore. They're practical tools that can help you: * Prove your async workflows are correct (yes, really!...

Authentication has come a long way since the primordial soup of simple passwords. Let's take a quick trip down memory lane: * Passwords: "Welcome123" (Facepalm) * Two-Factor Authentication: "Here's a code....

TL;DR We'll be optimizing these key areas: * NIC offloading techniques * TCP_QUICKACK for reduced latency * net.core.rmem_max tuning * SO_BUSY_POLL for CPU efficiency * Strategies to minimize latency spikes The Need...

Well, congratulations! You've just stumbled upon the world of encryption patterns. In the digital realm, we're all secret agents protecting our data from prying eyes. Let's dive into the fascinating...

You're knee-deep in a serverless project, feeling like a coding superhero. Suddenly, you're hit with a kryptonite-level challenge – orchestrating long-running workflows. Your functions are scattering faster than you can say "eventual...

TL;DR Rust's type system, with its phantom types and linear typing, allows us to enforce thread-safety at compile-time, often eliminating the need for runtime synchronization primitives like Arc and Mutex. This approach leverages...

In this deep dive, we're going to roll up our sleeves and get our hands dirty with advanced error propagation mechanisms. We'll explore how to build a custom fault tolerance layer that...

Before we dive into the carnage, let's remind ourselves why we fell for event sourcing in the first place: * Complete audit trail? Check. * Ability to reconstruct past states? Check. * Flexibility to evolve our domain...

Microservices are great, aren't they? They promise scalability, flexibility, and easier maintenance. But let's face it, they also come with their own set of challenges. One of the biggest headaches? Updating components...

CockroachDB uses Serializable Snapshot Isolation to maintain consistency across distributed nodes. It employs timestamp ordering, write intents, and clever contention handling to ensure that transactions behave as if they were executed serially, even when they'...

Rust's ownership model and fearless concurrency make it a powerhouse for building robust, high-performance backend services. We'll explore advanced patterns like work stealing, actor models, and lock-free data structures that'll...

The Security Trifecta: SELinux, OPA, and Falco Before we jump into the nitty-gritty, let's break down our security dream team: * SELinux: The grumpy old security guard that's been around the block. * OPA:...

Why Bypass the Kernel? The Linux kernel's network stack is a marvel of engineering, handling a wide variety of protocols and use cases. But for some high-performance applications, it can be overkill. Think of...

First things first: What the heck are tombstones, and why are they causing so much trouble? Tombstones are Cassandra's way of marking deleted data. They're like little gravestones for your bits and...
