Notes on building AI that actually works.

RAG and semantic search, LLM integrations, agent pipelines and the backends underneath — practical posts written while shipping.

Why was that request blocked? Tracing one customer at 100% with Cloudflare Traces and Trace Rules

Cloudflare Traces (open beta) shows a request's path through WAF rules, transforms, cache, Workers and origin as one trace. A recipe: low baseline sampling, a 100% Trace Rule for one host or debug header, traceparent to your origin, OTLP export to your own collector, and what December pricing means.

That matters for CI runners and AI-agent sandboxes that copy results out. Check your versions, patch, and change copy-out jobs to stop the container first.#docker#security#cve#ci

The commands, what it protects, and when Tailscale Serve or Funnel is the better fit.#cloudflare#tailscale#tunnels#security

Oct 5, 2026 · 6 min read.si after 'Super Intelligence': did one UN speech move a ccTLD?Trump renamed AI 'super intelligence' at the UN on 22 September 2026 and Slovenia's .si went from about 190,000 names to almost 276,000 in a month. Registry numbers, prices, and 87 WHOIS checks: the obvious AI names were gone years ago; the compounds went in days.#domains#si#tld#data

Oct 2, 2026 · 10 min readSteal Palantir's agent stack: typed tools, one LLM gateway, swappable modelsAn X thread boils Palantir's AIP docs down to four agent patterns. We check each one against the docs, then build them in one stdlib-only Python file: typed business-object tools, a gateway that masks PII, caches and retries, a model set in config, and schedule/event/API triggers.#ai-agents#llm#python#architecture

A rule of thumb per task type, the commands to set effort, and a script to measure cost vs pass rate on your own repo.#claude-code#ai-coding#llm#developer-tools

// what I write about — and build

Three topics. Also three things I build for clients.

Every topic has posts to read and a free quote if you want it built for your data and systems.

RAG & semantic search

Search and assistants that answer from your own documents — with sources, and a handoff when they’re not sure.

Embeddings & vector search
Hybrid keyword + meaning search
Assistants with citations

AI integrations

LLMs wired into the systems you already run — tickets, CRM, catalog, inbox — with costs and quality you can see.

Summaries, drafts, classification
Translations and content generation
APIs, webhooks, your own model

Agent pipelines

Multi-step agents as inspectable workflows — they plan, act and check, and a person approves anything that matters.

Workflows you can open and trace
Human approval steps
Event-driven, retry-safe backends
