One upgrade, three outages: glibc, cgroups, and a placeholder bug

This is the last of three parts. In part one I split my personal services onto their own two-node cluster. In part two I read the orchestrator's source and fixed two bugs, which shipped in the next release. This part is what happened when I installed that release. It broke the cluster three separate ways. None of them shared a root cause. Here they are in the order I hit them. I copied the official release binary to the second node and the service went into a crash loop: /usr/local/bin/orca: /li

Stop Choosing Between BM25 and Vector Search: Implement Hybrid Search with RRF

Combine dense embeddings and sparse keyword search using Reciprocal Rank Fusion to eliminate retrieval failure modes in production RAG systems. Most production RAG pipelines start with pure vector search. It works reliably during initial demos, but fails quietly once users begin searching for exact product IDs, error codes, or domain-specific identifiers. Vector search translates text into semantic coordinate spaces. Because dense models optimize for high-level concepts, they tend to blur fine-g

Why Sweating the Details Matter: Flask, port 5000, localhost, Safari and macOS

Pop quiz: Suppose you are developing a Flask app. Flask uses port 5000 as its default port. Now suppose that you have your Flask app running on macOS on port 5000. You're testing in Safari1 and you enter this URL into the address bar: http://localhost:5000. Question: What will happen? Answer: You won't get your Flask app. Instead, you'll likely get a whole lot of nothing, which can be very confusing because of two overlapping factors. It turns out, 5000 is the default port for AirPlay. You might

Google further buries search results under AI mode

Google is now automatically expanding its AI search summaries at the top of the results page for some searches, as reported by Search Engine Roundtable. The change, when it kicks in, pushes the typical list of links from a search much farther down Google's results page; instead of seeing part of an AI Overview with a "Show more" button you can click, you'll Google will show a full AI Overview at the top of your search, an "Ask anything" box under that, and then the list of links. It can lead to

My spidey sense on AI

This is me being honest with myself for a minute. The New York Times published a newsletter where the headline was OpenAI and 100 Others Warn that Window to Defend Against AI Attacks is Narrowing. Meaning as little as the efforts I have made towards my project for the past few months requires me to dig even deeper. The core of it all is defenders need to move faster than the attackers, because AI enabled attacks are getting cheaper to orchestrate and very difficult to remediate. How are you pr

Google Says Gemini App Has Surpassed 1 Billion Monthly Active Users, Its Fastest-Growing Product

Google says the Gemini app has surpassed 1 billion monthly active users, making it the fastest-growing product in the company's history. The milestone is more than a large user count. It shows how Google's strategy of placing Gemini across familiar products and devices is turning an AI assistant into a widely used consumer interface for voice, visual and multimodal tasks. In its official Gemini app milestone announcement, Google points to several indicators of how that adoption is taking shape:
