AWS retired its free database migration assessment tool. The reason should change how you build developer tools.

On May 20, 2026, AWS ended support for DMS Fleet Advisor. Fleet Advisor answered a question every migration team asks first: what is actually in my database estate, and how hard will it be to move? It was free. It was fully managed. It was backed by the largest cloud provider on earth. It still lost. AWS's official notice says only: "After careful consideration, we decided to end support for AWS DMS Fleet Advisor." No reason given. But you don't need one — the documentation tells you. Here is what Fleet Advisor required before it would tell you a single thing about your databases: Install a standalone data collector in your local environment Create an Amazon S3 bucket Create IAM policies, roles, and users — via CloudFormation, which was the recommended path Create database users with the minimum required permissions on every source Establish network access from the collector to each database server Then you'd meet the ceilings: recommendations for up to 100 databases at a time, one-to-one target mapping only, no multitenant server support. Now picture running that gauntlet inside a bank. You are a Business Solution Architect. You have been asked to scope a migration. You do not yet have approval for the migration — that approval is what the assessment is for . And to produce the assessment, you must first request production database credentials, get an agent binary through software approval, provision an S3 bucket, and get an IAM stack past a security review. That is a six-week procurement conversation to answer a question you were hoping to answer this week. AWS's replacement recommendation is Migration Evaluator — a consulting-led engagement. Read that as the finding it is: AWS looked at self-serve migration assessment, and concluded that humans and services do it better than a product. I think they were half right. And the half they got wrong is the interesting part. The lesson: friction is a competitor, and it usually wins We talk about developer tools as if the

Python, PostgreSQL, and MQTT

Why this combination keeps winning for IoT telemetry backends — not in a benchmark, but against flaky gateways, replayed data, and firmware that never quite agrees with itself. If you’ve ever built the backend for a fleet of IoT devices — sensors, gateways, industrial equipment reporting temperature, humidity, GPS, battery, signal strength — you’ve faced the same fork in the road early on: what do you build the ingestion layer with, and what do you store the data in? After building a telemetry backend from scratch for a real fleet of LoRa/BLE sensors and gateways — handling dual ingestion paths, binary and JSON payload formats, automatic recovery of lost data, and a growing set of operational dashboards — I keep coming back to the same combination: Python (FastAPI + asyncio) for the API, MQTT for device transport, and PostgreSQL for storage. Here’s why that combination holds up so well for this specific problem, not just “in general.” Full Article: https://medium.com/@jackpelorus/python-postgresql-and-mqtt-the-boring-stack-that-actually-survives-a-real-device-fleet-9297146cbe8d?sharedUserId=jackpelorus

xAI’s last-minute scramble to stop Minnesota’s anti-nudification app law

xAI is suing Minnesota Attorney General Keith Ellison over a law passed back in May that broadly targets "nudification" apps, claiming that the statute's punitive provisions leave the company with "no practical choice but to restrict Grok Imagine's image-editing features in various ways." The law, the company argues, violates the First Amendment. Back in January, […]

Building an AI Operating Layer - Episode 1: Why I Didn't Start Sooner

Building an AI Operating Layer Episode 1 Why I Didn't Start Sooner Most engineering projects begin with an idea. This one began with a question. For months I found myself watching the explosion of AI tools, frameworks, models, and agent platforms. Every week there seemed to be another breakthrough, another library, and another opinion about where everything was headed. I could have started building immediately. Part of me thought I should have. But I realized something, and it kept bothering me. I wasn't afraid of writing code. I was afraid of solving the wrong problem. When a new technology appears, it's easy to jump straight into implementation. Pick a framework. Choose a model. Build something. Ship it. I didn't want to start there because I had a feeling there was a much bigger picture that I wasn't seeing yet. So I waited. I spent my time reading, experimenting, asking questions, and trying to understand how all of these pieces connected. The more I learned, the more I realized I wasn't actually interested in building another AI application. What fascinated me was the system behind the systems. What happens when you stop looking at models, memory, orchestration, tools, policies, and execution as separate ideas and start seeing them as parts of a much larger ecosystem? That question became the beginning of this project. This isn't a story about predicting the future. It's a story about trying to understand it. I'm sure some of my assumptions will be wrong. I'm sure parts of this architecture will change. If they do, you'll see that too. I don't want this journal to only show the polished results. I want it to capture the discoveries, the wrong turns, the redesigns, and the moments where a better idea replaces an old one. At the center of this journey is a project I'm calling the AI Operating Layer. Today it's mostly architecture, documentation, research, prototypes, and a growing collection of ideas. Maybe that's exactly where projects like this should begin. I'

Cyberpunk 2077 packs a lot of fun into its discounted $20 price

Over the last few years, CD Projekt Red put a ton of work into fixing Cyberpunk 2077, squashing bugs, polishing content, and even launching new DLC in 2023, Phantom Liberty. As a result, this game has gone from a source for funny, glitch-fueled videos to a world I’ve returned to a number of times to […]
