How to prepare your website for Black Friday: the 12-week plan

Black Friday 2026 lands on 27 November. That is eleven weeks from today, and most sites that fail that morning failed weeks earlier, when nobody rehearsed the traffic. What follows is a twelve-week countdown, so you are already a week behind. That is fine. The order matters more than the calendar: targets before testing, testing before fixing, fixing before freezing, and no unproven code into the day. A website is ready when it can serve the peak number of simultaneous shoppers you expect, at sp

React Server Components para veteranos de SPA

React Server Components para veteranos de SPA Ya sabes construir una SPA. Has publicado varias. Usas useState, usas useEffect, montas un fetch, y a estas alturas escribes esa estructura casi sin pensarla. Los Server Components rompen ese automatismo. Casi todas las explicaciones que vas a encontrar arrancan desde el lado del framework: el routing, el bundling, el formato en que viajan los datos. Para alguien que ya tiene un modelo mental armado y funcionando, ese orden es el peor posible. Así

React Server Components for SPA Veterans

React Server Components for SPA Veterans You already know how to build a single-page app. You have shipped several. You reach for useState, you reach for useEffect, you wire up a fetch, and by now the shape of that code arrives before the thought does. Server Components break the reflex. Most explanations of them start from the framework's side — routing, bundling, the wire format — which is exactly backwards for a developer whose mental model is already built and working. So this one starts f

Agentic Commerce: A Practical 2026 Guide

Agentic Commerce: A Practical 2026 Guide Last updated: 2026-08-15 Version: 1.0 Next review: 2027-08-15 The rise of AI agents in commerce is real and accelerating. Today's autonomous buyers—whether they're AI assistants, automated trading bots, or intelligent procurement systems—don't just browse listings; they evaluate, compare, and purchase based on structured data, performance metrics, and predefined criteria. This isn't science fiction. It's happening now, and it's changing how we think a

How to send HTML form data to an email address

You have a static page with a contact form. You want what people write in it to arrive in your inbox. You search, and half the answers say mailto:, the other half say "use a backend", and nobody tells you which details will bite you at 2am when a customer says they wrote and you never got it. Here is the whole picture: why HTML alone can't do this, the three options that actually work, and the failure modes each one has. A <form> element does exactly one thing: it takes the fields, encodes them,

Taking apart a result that (never) worked

Sometimes, being restless about small things is a good trait. It helps to dismantle a beautiful facade that hides broken machinery inside, and as such clears the ground for building something that does actual work. That's exactly what happened with my RL experiment, and this is my story about it. The setup: a known EGFR inhibitor (a molecule that blocks EGFR, a receptor whose overactivity drives several cancers), fifteen steps to improve it, a composite score combining predicted activity with dr
