Qwen3 locally with Ollama: what changed in the architecture and whether it's worth switching

Qwen3 landed with thinking mode and real improvements in code generation. But before you replace the model already running in your Ollama setup, there are technical questions you need to answer first. I answer them here without selling hype.

OWASP LLM Top 10 in Production: How I Audited My TypeScript Agent Pipeline Against All 10 Risks — and What I Found

Running the OWASP LLM Top 10 as a real audit is a completely different experience than reading it as a checklist. I ran it against my TypeScript agent stack with system prompts, MCP tools, and Cline — and the findings were uncomfortable.

MCP Model Context Protocol in TypeScript: build portable tools across Claude, GPT, and local models

The most common mistake when implementing MCP tools is coupling them to the provider's SDK. The spec exists to prevent exactly that. A practical architecture guide: the input/output contract that makes a tool work across Claude, GPT, and local models without rewriting anything.

Cline in VS Code: I used it two weeks on a TypeScript project and this survived

Two weeks using Cline as an autonomous coding agent on a TypeScript project. What tasks I delegated, where it screwed up, how it compares to Claude Code, and which workflows I'd never hand over to it. Architecture-grade analysis, not hype.

Real guardrails for autonomous agents after one almost destroyed my infrastructure

After an autonomous agent nearly wiped my production database, I built a real guardrails layer. Here are the controls, the code, and the logs that saved my skin.

Agents That Create Accounts, Buy Domains, and Deploy on Their Own: I Tested It Against My Real Stack — Here's What Broke (and What Worked)

The viral HN demo shows Cloudflare agents running the full infra cycle with zero human intervention. I replicated it against my Railway stack and documented exactly what the agent executed on its own, where I had to step in, and what permissions it asked for that it absolutely shouldn't have. Real a

DeepClaude: I Combined Claude Code with DeepSeek V4 Pro in My Agent Loop and the Numbers Threw Me Off

I took the DeepClaude repo (467 points on HN) and dropped it into my real production loop. The combination isn't simply "better than either alone" — there's a specific task regime where DeepSeek V4 Pro destroys and Claude fails, and vice versa. Here are my actual numbers.

Specsmaxxing: I Wrote YAML Specs for My AI Agents — Here's What Changed (and What Didn't)

Specsmaxxing promises to cure "AI psychosis" with YAML specs for agents. I applied it to my real workflow with Claude Code and found the trap nobody mentions: the quality problem doesn't disappear — it moves into the YAML.

I tried to reproduce the OpenClaw case in Claude Code: my result contradicts the viral post

The HN thread claimed Claude Code blocked or redirected billing when OpenClaw appeared in Git history. I built a public repo, a reproducible harness, and ran the matrix. On Claude Code 2.1.126, I did not reproduce the block.
