What we're building By the end of this tutorial, you'll have a working mental model — and working code — for implementing Conflict-Free Replicated Data Types in Kotlin Multiplatform shared code. We'll build an LWW-Register, compare state-based vs operation-based sync strategies, and walk through the architecture that lets you replace your entire sync backend with dumb blob storage. Let me show you a pattern I use in every project with offline-first requirements. Prerequisites Kotlin Multiplat... Read more ›
I tried solving Leetcode problem #10( Regular Expression Matching) for fun, ended up spending hours on it. problem Link: I took a naive greedy string construction approach to check if the string s matched the pattern p. That worked for simple cases where: p="a*b" s="aaab" output:True But failed in cases where p ="ab*a*c*a" and s ="aaa", output should be True why greedy string construction failed: the flaw was that a* is not a single choice, it can match "", "a", "aa", "aaa" etc. To determine ...

I built BibaVPN for one reason: I did not want to hand traffic to a third-party VPN provider. It is a self-hosted SOCKS5 / HTTP CONNECT tunnel over TLS + WebSocket, with a Rust core and Android/Desktop clients. Some users in Russia, Iran, and China use it to get around network blocks through their own VPS. The project is small on purpose. It is not trying to be a full private network stack. It is meant for private, self-hosted access in restrictive environments. GitHub: Read more ›

Have you seen those new AI-generated review summaries on Amazon? They are incredibly useful for buyers, but there’s a catch: they are completely locked inside Amazon’s ecosystem. If you are a developer, PM, or data scientist trying to analyze 5,000 scattered App Store reviews, Shopify comments, or Zendesk tickets, you are still stuck doing it manually or relying on basic word clouds. I wanted to fix that. So, I built NEXUS 🧠—a production-grade Review Intelligence Engine that brings that exact... Read more ›
Series context (Part 4 of 8): This article assumes familiarity with . Understanding why consistency guarantees are hard at the database layer is essential context before introducing distributed patterns here. Why Microservices in Banking? Microservices in banking is the architectural pattern where a core banking system is broken into independently deployable, domain-owned services (CIF, Payments, Lending, Notifications) connected by an event bus instead of direct database calls. This replaces... Read more ›
This release brings Load Test Schedules — a long-requested feature that lets you run a load test automatically at specific times, so you no longer need to kick it off manually. We've also extended the Container Spec file, which now supports more standard Kubernetes settings and gives you the flexibility to pass secrets and other arguments via environment variables. Highlights: • ⏰ Scheduled load test execution • ☸️ Enhanced Kubernetes Container Spec support • 🔐 More flexible auth configuratio... Read more ›

Why race‑condition crashes only appear under specific timing, vanish under debugging, and produce different stack traces on every run. Race‑condition crashes are the first pattern in the series where the failure is not deterministic. The code is correct, the memory is valid, the backtrace may look reasonable, and the crash may even disappear under debugging — but the program still fails unpredictably. S5 crashes are timing‑dependent failures caused by two or more threads accessing shared stat... Read more ›
For years I treated burnout as a personal failing. If I was tired, I needed more sleep. If I was anxious on Sunday night, I needed to meditate. If I dreaded standup, I needed a better attitude. None of it worked, because I was treating an organizational problem as a character problem. Senior engineer burnout rarely looks like simple exhaustion. It looks like your pull request reviews getting slower. It looks like tech debt you keep meaning to document and never do. It looks like every "quick ... Read more ›
Google Sheets recalculates cells twice as fast after shifting its compute engine to WebAssembly. Figma cut initial load time by 3x. Shopify executes custom checkout rules compiled from Rust to Wasm at the CDN edge - all in production, serving millions of users every day. WebAssembly started as a way to bring C++ into the browser. Today, in 2026, it is a universal binary runtime that executes in browsers, edge networks, serverless functions, and even AI inference pipelines. The W3C ratified Wa... Read more ›
Every AI coding tool claims to make you faster. Most of them do — but not in the same way, and not for the same tasks. Picking the wrong tool for your workflow doesn't just waste $20 a month — it creates friction exactly where you need acceleration. The four tools developers actually debate in 2026 differ at the architecture level, not the feature level: GitHub Copilot — built for inline completion inside your existing IDE. Cursor — built around reading your entire codebase. Claude Code — a t... Read more ›

Redis has a reputation for being a serious piece of infrastructure, and it is. But the core of it, the part that makes it Redis, is astonishingly small. Small enough that you can rebuild it in about 80 lines of Python, point the real redis-cli at your version, and have it just work. Same commands, same wire protocol, same behavior. That is the fun of it. By the end you will run redis-cli -p 6399 set foo bar, and the OK that comes back is from a server you wrote. This is the written companion ... Read more ›
The etcd Endpoint Trap A cluster migration just took your whole control plane offline. In the next few minutes you'll find out why, and fix it the way the CKA exam expects. This is a CKA Troubleshooting walkthrough. Every command below is real output from a live cluster, and you can reproduce the whole thing yourself (scripts at the end). The scenario A single-node kubeadm cluster was migrated to a new machine. The control plane won't come up. Your task: identify the broken component, find th... Read more ›
Expo SDK 56 ships with a custom Kotlin compiler plugin that eliminates reflection from Expo Modules on Android. The result: 70% faster module initialization and a 30% reduction in time to first render. The plugin runs during compilation, so app developers get these performance gains automatically without changing any code. Module authors can unlock even bigger wins with a single annotation. This post walks through how we built it and why this approach succeeded where previous attempts failed.... Read more ›

RLHF vs DPO vs IPO vs KTO: which alignment method should you use You have a base model, say Llama 3.2 8B, that can write poetry in any meter and pass the bar exam. It can also generate instructions for synthesizing controlled substances, roleplay as a manipulative therapist, and explain in loving detail why your pull request is an affront to good taste. You need to align it — remove the harmful outputs while keeping the capability. Your mentor says "use RLHF." A paper on your feed says DPO is... Read more ›
