ENGINEERING

33 Software Engineering Books, Distilled

The 33 canon software engineering books, each boiled down to the few lessons it most wants you to carry into how you build, lead, and think. Outcomes over output.
AI-AGENTS

AI Killed Your Last Excuse

AI didn't make engineering easier. It made it harder. The busywork is gone, so the only thing left to own is the accountability.
AI-AGENTS

How I code with AI

How I get AI to write reliable code.

Tokens are LEGO bricks: Your Life in Five Words

Intelligence is compression: saying the most with the fewest words. A thought experiment with five words, and what AI and a quiet Sunday taught me about the tokens we build a life from.
OPENCLAW N8N

What You Should Be Automating in Your Business

A food-for-thought menu of what to automate across sales, marketing, support, finance, and operations, plus the tools it takes to actually run them.
SECOND-BRAIN

Your Second Brain Was Never a Second Brain

Your note app was never a second brain, it was a second job. A real AI second brain organizes itself, so you can delegate the busy work by voice.
AI-AGENTS

Give Agents the Busywork, Keep the Brain

AI should automate your busywork, not your brain. Where to draw the line, what to protect, and the burnout trap nobody warns you about.
NOTION

Why I Stopped Using Notion

I do not organize anything by hand anymore. I share an idea, my agent files it in a format it can find again, and my only job is the vision.
OPENCLAW N8N

OpenClaw vs n8n Agents

OpenClaw vs n8n agents: two very different tools. Use n8n for your fixed, Zapier-style workflows, and OpenClaw for agentic, conversational automation with almost no maintenance.
OPENCLAW

How Can I Use OpenClaw?

OpenClaw is an AI agent that runs on a computer you own and works through your apps like a teammate you hired. What you can use it for, and why it needs its own machine.

N8N

Build Custom n8n Nodes & Deploy with Kamal

Build a reusable custom n8n node from scratch and ship it to production with Kamal. Watch the full build, grab the starter repo, and run it on your own infrastructure.
N8N

Export n8n Workflows Between Docker Containers

Move n8n workflows and credentials out of one container and into another. The export and import flow, the encryption-key catch, and when to reach for Kamal instead.
AI-AGENTS

How AI Agents Actually Work

An AI agent is not magic. It is a normal AI call in a loop, where deterministic code runs the tools the model asks for and feeds the results back.
N8N

n8n Environment Variables Cheat Sheet

Copy-paste .env for n8n in Docker: encryption key, WEBHOOK_URL, execution pruning, Redis queue. The settings you must get right before first prod boot.
N8N

Web Scraping: Lower Your Expectations

If you run a company and are about to just scrape it, scale back the dream. Use a tool like Apify or Bright Data, buy the data from a provider, and forget the locked-down sites.
N8N

10 Production-Ready n8n Workflow Examples

Ten n8n automations worth building, explained for business owners: what each one actually does for you, and why it is worth your time.

AI for Healthcare

AI in healthcare is not a model problem, it is a compliance problem. Data on US soil, encrypted, audited, and HIPAA-covered through the right provider.
DATABASES

What Is Supabase?

Supabase, explained for founders: a smart Airtable for software. It is Postgres plus a batteries-included backend, so your developer can ship fast.
N8N

30 Best n8n Community Nodes (2025)

The n8n community nodes worth installing in 2025: what each one does and when to reach for it.

What Is Multitenancy?

Multitenancy explained for founders: how one app serves many customers without their data ever mixing, the two ways to build it, and which one to pick.
UPWORK

How I'd Make It on Upwork in 90 Days

I broke even on Upwork after two months and 17,000 connects. The 90-day playbook I'd run if I started today: niche down, charge for pilots, automate last.
MCP

5 Ways People Misuse MCP Servers

MCP connects AI agents to your tools. The five mistakes that wreck MCP servers in production: blobs over references, polling, guessable IDs, kitchen-sink servers, and no security.
N8N OPENCLAW

The Real Way to Automate Upwork Bidding

The honest version: the best Upwork automation is a person. Scrape your job alerts, pre-validate, let an agent draft, and a VA do the work while you track the ratio.
MCP

What Is an MCP?

An MCP connects an app you already use to your AI agent, so the agent can read its live data and act on it. The plain-English version for founders.
AI-AGENTS

Why Would You Run Local AI?

Two real reasons to run AI on your own machine instead of the cloud: keeping sensitive data private, and not paying per token as prices climb.
N8N

Zapier vs Make vs n8n

It is a credential war: whoever has the most easy-to-connect integrations wins. The real catch is not the billing, it is lock-in. And it is not a big decision.
ARCHITECTURE

Monolith or Microservices? Start With the Monolith

Monolith vs microservices is a team and culture choice, not a tech one. Why small teams should start monolithic, what Conway's Law really means, and when microservices pay off.
