The Wall Street Journal ran a piece yesterday on JustPaid, a 9-person Mountain View startup. They used OpenClaw and Claude Code to stand up seven AI agents that write code, review it, and run QA around the clock. In one month: 10 major features shipped. Each one would have taken a human engineer a month or more. This story is getting passed around as proof that the autonomous engineering team is h
MCP vs Skills: a practical decision guide for builders I need my agent to do X. Skill or MCP? If you build agents on Claude or anything MCP-compatible, this is the question that actually matters. The two patterns get pitched as alternatives. They are not. They solve different problems. Most production agents need both. Here is the decision rule, the framing for each, and the anti-patterns I keep
PostgreSQL Query Rewriting Techniques The previous articles in this series covered performance problems you fix by adding indexes, restructuring joins, or tuning memory. This one is about the queries where the plan is "fine" — every node is doing something reasonable — but the query itself is asking the wrong question, producing unnecessarily large intermediate results or forcing the planner dow
In March 2026, a rogue AI agent at Meta triggered a Sev 1 security incident. Sensitive company and user data was exposed to unauthorized employees for nearly two hours. The agent held valid credentials. It operated inside authorized boundaries. It passed every identity check. And yet. Identity and Access Management answers one question: Is this agent who it says it is? It doesn't answer: Was this
SQL is widely known for data querying and manipulation but systems do grow; data becomes larger; processes become repetitive and operations become sensitive. SQL has some features which enables it to be considered a fully fledged programming language. Some of the features which I discuss in this article are procedures, functions and transactions. Each of these concepts serve distinct purposes. Sto
The Problem Nobody Talks About AI can write code, generate content, analyze data, design systems, and manage projects. It's getting better every month. The natural question: what's left for humans? The wrong answer: "AI will replace us." The right answer is uncomfortable: stop picking the best AI. Run multiple AIs in competition, and become the judge. Three rules, learned the hard way: Multiple
Hi 👋, In this post we shall explore Bedrock's structured KB with this architecture: Upload CSVs to S3 > SNS Queue > Crawl data with Glue > Query with Redshift > Bedrock KB > Query with LLM. Let's do some of this with code. Let's get started. Clone the repo and switch to the project directory. git clone [email protected]:networkandcode/networkandcode.github.io.git cd structured-kb-demo/ Do a uv sync
Subqueries vs. CTEs in SQL: A Practical Guide to Writing Cleaner, Smarter Queries Whether you're just getting comfortable with SQL or leveling up your data skills, two tools will come up again and again when working with complex queries: subqueries and Common Table Expressions (CTEs). They solve similar problems — breaking a complex query into manageable pieces — but they do it in different ways
