Postmortem: How a Corrupted Node Modules Folder Caused 3-Hour Outage for Our CI Pipeline Published: October 26, 2024 | Author: DevOps Team | 5 min read On October 24, 2024, our team experienced a 3-hour, 12-minute outage of our primary CI/CD pipeline, impacting 47 active pull requests and delaying 3 production releases. The root cause was identified as a corrupted node_modules directory on our s
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

Your requests may look like a real browser, but they’re still getting blocked. Even when requests include realistic headers, they can still be detected if HTTP/2 behavior, such as header ordering, pseudo-header structure, and frame sequencing, does not match real browsers. These low-level inconsistencies reduce stability and reliability, making automated traffic easier to identify. In HTTP/2, head
I opened IBM Course 4 — Python for Data Science, AI and Development — fully expecting to breeze through it. I'd used Python before. In college. In personal projects. It was supposed to be the comfortable one. Then **kwargs showed up. My previous post went up on May 2. After that, I finished IBM Course 3 on Prompt Engineering. May 3 — started Course 4. Finished a major chunk of it the same day. May
I'm working on an AI Data Analyst in MLJAR Studio. The idea is simple: you ask a question in natural language, AI writes Python code, executes it, and shows the result. But recently I found a small example that reminded me why AI data analysis needs more than code generation. I was testing a medical data analysis use case with a diabetes CSV file. The first task was simple: load data from this URL
In Q3 2024, a production AI incident classifier mislabeled 42% of critical security incidents as 'low priority' over 72 hours, causing $2.1M in SLA breach penalties and a 19% drop in enterprise customer retention. Root cause? A toxic combination of unmitigated training data bias and silent breaking changes in Scikit-Learn 1.5 that invalidated our model calibration pipeline. Google Chrome silentl
