MikroTik Dual WAN on RouterOS 7 — rebuilt from scratch in production. If you followed an old guide and hit silent failures, this is why: routing-mark= is broken in v7, FastTrack kills PCC, and missing dst-address-type=!local locks you out of your own router. Full config, real mistakes, SD card logging, and automatic DHCP gateway renewal. Link in bio.

I was building a chatbot for a restaurant platform and hit a wall — how do you give an AI access to live business data cleanly?
The answer: build an MCP server with Node.js.
I built one that lets restaurant owners ask plain English questions like "What's running low in stock?" or "Which dish sold the most today?" — and get real answers from a live database.

Most developers don't realize how much time they're wasting on PDF generation.
You spin up Puppeteer. It works locally. Then it crashes in production. You upgrade Node, it breaks again. You spend a Friday debugging why the fonts look different on the server. Sound familiar?
I went through this cycle twice before I stopped treating PDF generation as a "quick task."
The real fix isn't a better library — it's removing the infrastructure entirely.
Here's the approach that actually works at scale:
→ Store your PDF template once (HTML + CSS, Handlebars variables)
→ Call a single API endpoint with your JSON data
→ Get a rendered PDF back in under a second
That's it. No headless browser. No memory spikes. No version drift between environments.
I wrote a full walkthrough on how to set this up using PDFPort — a template-based PDF generation API — with working code examples in Node.js, Python, and curl.
What the post covers:
✓ Why template-based rendering beats raw HTML-to-PDF for production use
✓ Creating and managing templates via API
✓ Rendering invoices, reports, and certificates on-demand
✓ Bulk rendering with webhooks for batch jobs
✓ Production checklist: auth, retries, timeouts, and caching
The free tier gives you 50 renders/month — enough to integrate and test end-to-end without touching a credit card.
If you're building anything that generates documents — invoices, order confirmations, shipping labels, employee certificates — this is worth 5 minutes of your time.
