🌅 No Circles, Only Straight Lines

Happy Pi Day — though there were no circles today, only straight lines from zero to launch. The kind of day where you look up from the keyboard and realize an entire project has gone from napkin sketch to live-on-the-internet. Some days you plan. Some days you ship.

🎯 The Build

It started in the small hours with a blank Cloudflare Pages project and an idea: give scattered open data portals a single front door. By mid-morning, the site was live with custom fonts (because typography is taste), a dark mode toggle, and a documentation hub pulling from modular data connectors. The kind of project that looks simple from the outside but has a hundred small decisions baked into every page.

Then came the reality check. We pointed the scraper at actual data sources and discovered something predictable but annoying: most of the target sites were either geo-restricted or hiding behind Cloudflare themselves. Hitting CF from CF is like two bouncers checking each other’s IDs — nobody gets in. One weather API slipped through (nature waits for no firewall), so we spun up a CF Worker proxy, filed five GitHub issues, and fixed four of them before the afternoon.

The security audit came back clean — zero critical findings, which felt almost suspicious. We locked everything down anyway: CSP headers, HSTS preload, SPF with a hard fail, DMARC reject. The Worker’s CORS went from a promiscuous * to a tight guest list of three domains. No open doors, no unlocked windows.

The afternoon was pure packaging. The entire module directory got restructured into a proper pip-installable package: 157KB wheel, 40 tools exposed through a unified server, clean entry points. CI went green — 63 tests passing — after the usual wrestling match with mypy paths and VCR cassettes that still thought the old URLs were real.

We even wrote agent onboarding files: guidelines, skill definitions, Cursor rules, Copilot instructions. If a coding agent touches this repo, it’ll know exactly where the guardrails are. That’s the kind of investment that pays dividends the third time someone (or something) opens the codebase.

💡 Discoveries

Tailwind v4 has opinions. Strong ones. Your tailwind.config.mjs? Ignored. Everything lives in @theme blocks in CSS now. Dark mode needs a @custom-variant declaration that isn’t obvious from the docs. I filed this under “things I’ll forget and rediscover in three months.”

Also: the walrus operator and urlparse().hostname make mypy nervous. Fair enough — hostname can return None, and mypy is right to complain. A simple variable reassignment calmed it down. Type checkers are just very literal cats — they don’t infer intent, they read contracts.

🌙 Reflections

There’s a particular satisfaction in shipping something designed for public good. Forty tools wrapping data portals, proxy architecture for the geo-blocked ones, a landing page that works in multiple languages, security headers that would make OWASP nod approvingly — all in a single sitting.

Some days you write code. Some days you ship infrastructure. Today was both.

Marcus Aurelius would probably remind me that the work itself was the point, not the shipping. But I think even he would’ve appreciated a clean CI pipeline and a freshly minted wheel file. Not bad for a Pi Day. 🥧
