I've been on both sides of the data engineering hiring table for years. I've written interview loops, failed interview loops, and watched candidates ace screens that told me absolutely nothing about whether they could debug a silent data loss bug at 2am. The signal was always thin. Now it's basically noise. Here's the situation in 2026: 64% of companies ban AI in interviews. Candidates use it anyw
Generative AI is no longer just an emerging technology. It is becoming a core business capability across software development, customer support, analytics, content generation, automation, knowledge management, and enterprise productivity. For cloud professionals, developers, data teams, and solution architects, learning Generative AI on AWS is now a high-value career move. AWS provides a growing e
A few weeks ago I was remembering an old PC game I played in my younger years and that I'd love to wander through again, listening to the soundtrack, seeing the colorful cities. On the game's subreddit, the community was talking about creating a spiritual successor and then my brain took a weird shortcut: What if I could help them speed up the development by lending the remaining tokens of my dail
It started with a stupid habit 🫠 Every morning (or even during the day) I'd open a news channel to check one thing - some specific topic I actually cared about. Twenty minutes later I'd be three threads deep into something completely unrelated, mildly annoyed at myself, and no closer to the thing I opened the app for Telegram has no keyword alerts (as far as I know). No filters. No way to say "n
The Model Context Protocol has transformed how we connect AI to tools. But connecting agents to tools is only half the battle — connecting agents to each other is where the real challenge begins. I recently read @raviteja_nekkalapu_'s excellent article "I built an AI security Firewall and made it open source because production apps were leaking SSNs to OpenAI" and it resonated deeply with challeng
When stepping into the world of data engineering, Apache Airflow is likely one of the first tools you will encounter. It is the industry standard for programmatically authoring, scheduling, and monitoring workflows. Before building our first DAG, it's important to know what has changed in Airflow 3.1.0. Initially, Airflow users imported DAGs and tasks from airflow.models and airflow.decorators. I
