Apache Stateful Functions is one of the quietly powerful frameworks in the Flink ecosystem - durable per-key state, exactly-once messaging, polyglot remote functions, all on top of Apache Flink. It's also been functionally dormant since October 2024, and it doesn't run on Flink 2.x. We needed it on Flink 2.x. So we maintained the continuation: kzmlabs/flink-statefun. This post is the why and the h
Motivation: Color as a “Type System” for Pictures If you have ever looked at a black-and-white cellular automaton that felt like pure static, you are not alone. Many classical diagrams of elementary rules compress rich structure into just two colors. As programmers, we already accept that types expose structure in code that is invisible in raw bytes. In this article, I will argue that well-desig
The Dangerous Bugs Are the Ones That Don't Crash: Building Input Validation for My MCP Server I was building an MCP server for an event platform that automates speaker communications (confirmations, reminders, calendar invites, follow-ups). An agent created a session confirmation for "Monday March 8th." March 8th was a Sunday. I caught it. But catching it was just the beginning. The confirmation

The Hidden Performance Cost of New Tab Extensions You install a new tab extension to make your browser nicer. You get weather, a clock, a background image. But then you notice Firefox feels... slower. The new tab hesitates before loading. Your CPU spikes for half a second. Here's what's probably happening — and how the good extensions avoid it. Every new tab load starts fresh. Your extension nee
tl;dr: TestSprite automates end-to-end testing via AI agents in 10-20 minutes. Zero manual QA work. Solid product—but there are locale/timezone gotchas if you're testing internationally. Here's what I found. I took their MCP Server integration and ran it against a personal project (a React e-commerce app with product filtering, checkout, and multi-currency support). The onboarding was genuinely fr
A hands-on review from an Indonesian developer's perspective I've been burned by testing tools before. The promise is always the same: "just add this to your project and testing is handled." Then you spend two hours fighting configuration, another hour writing boilerplate, and you end up with 20 tests that break every time you rename a variable. So when I heard about TestSprite — an autonomous AI
