Luz y Oscuridad
La sombra integrada se vuelve herramienta. La reprimida se vuelve destino.

Lo que el gimnasio me enseñó.
Poseidón en el Caribe
El dios del mar no castiga con tormentas. Castiga con indiferencia.
Recargando
El Oura llevaba semanas hablando más fuerte que la agenda. Una noche en Múcura, Punta Faro, y los scores saltaron del 60% al 90%. Descansar también es protocolo.
Saludos desde el paraíso
Cumplí cada intención que me propuse para 2026 — y las superé por mucho más de lo que esperaba. Y todavía vamos por la mitad. El resto, cuando vuelva.
Opus 4.8 Would Rather Tell You It Failed
Anthropic's fourth Opus model in six months. The story isn't another point on SWE-bench, it's a model that flags its own broken code and a tool that lets one agent command hundreds. An honest scorecard from someone who runs agents all day.
La Herida Que No Cierra
El narcisista no pierde como pierden los demás. Su problema no es la derrota, sino la imposibilidad estructural de metabolizarla.
The Abdomen Said No
Week 5 of the protocol, three updates: a NAD+ technique that finally works, an abdomen running out of real estate, and a primary-site switch to the lateral thigh.
Hágale Pues
Empezó con keto flu y terminó con el peque dormido en el hombro de Gaby. En el medio: un tamal casero que destruyó la dieta — con justificación metabólica, fútbol, gym y un día completo paisa.
Hoy entrenamos, señor
Le escribí al maestro para confirmar el descanso. Le pregunté a los pelaos si querían quedarse. Las dos respuestas me dejaron sin excusa.
My Agent Filed Its Own Ticket
I handed a PR review to an agent. It silently created a follow-up ticket because the reviewer said "or". Welcome to prompt injection lite — and the same mechanism that, with a hostile reviewer, ends in your .env being curl'd to a stranger.
Grok Build
xAI's terminal coding agent. Plan Mode by default, eight parallel subagents, Grok 4.3 Heavy under the hood, AGENTS.md / MCP / Skills compatible. The bets it makes, where to test them, and how to evaluate without religion.

Codex Mobile
OpenAI shipped Codex inside the ChatGPT mobile app. Not a mobile IDE — a remote control surface for agent work. Pair once, supervise all your projects from the phone. The execution boundary is the product.

Final NAD+ Adjustment
The NAD+ protocol moves to 100mg Wed-Sun AM: same 500mg weekly exposure, 60% lower per-session peak, cleaner timing, simpler hardware, and a monitoring window to prove it.

Claude for Legal Is Claude Code Wearing a Suit
Anthropic's May 12 launch matters less as a chatbot than as a connector-driven agent stack for legal work. Plugins, MCP connectors, Microsoft 365, Managed Agents — the architectural lineage matters more than the demo.

Sinapt: The Architecture Before the Code
After three Sinapt manifestos, the architecture has answers. Two layers locked: retrieval and contract surfaces. The PoC has not run. Dogfood has not run. Not a victory lap — but the architecture has stopped being hand-wavy where hand-wavy kills the product.

La muerte y el día de la madre
Belgrado, Villa de Leyva, una colina con un Cristo blanco en la cima. Lo que Snežana dejó funcionando, y lo que se hereda cuando la madre llegó entera.

SaaSpocalypse
Wall Street saw $285 billion vanish in a 24-hour SaaSpocalypse. The version on my desk has been quieter — JetBrains canceled today, finance app gone last quarter, half the subscription drawer empty in a year. The user-developer collapse is personal first.
AI
Above the Model
The model is not the bottleneck anymore. The plumbing is well-known. What separates teams shipping transformative AI from teams shipping generic slop is a stack of less-discussed components: context, dreaming, sycophancy mitigation, verification, memory. The operator's manual.

MCP, From Pidgin to Protocol
Before MCP, every AI integration was its own pidgin — improvised, simplified, just enough to get one client talking to one tool. Five floors from the first shared word to a real protocol: what MCP is, when to use it, every server worth running, the failure modes teams hit.
AI
RAG, From Crayons to PhD
Five floors of understanding: a kid version, an engineer version, a tools-and-cases version, an advanced version, a PhD version. By the end you'll know what RAG is, when to use it, when to run, every tool worth caring about, and the hot takes most posts won't tell you.

Day 11: Best Night, Best Numbers, Worst Rush
Day 11 of the protocol. First seven-plus-hour sleep in the entire dataset. New HRV ceiling, weight a kilogram and a half down, blood pressure dialed in. Then the morning NAD+ pulse hit harder at half the dose than the original at full dose.

BDI 2: What the Intake Strip Did to My Sleep Data in One Night
Yesterday's nasal-strip article promised the Oura the next morning would be the discriminator. The discriminator landed. BDI dropped 67%, SpO₂ jumped 5.5 percentage points — both the best readings in the three-week dataset. Plus the awkward complication.

AI — Haters vs Believers
A war between AI haters and AI believers. A quieter, more dangerous third group nobody's writing about: the silent passive-aggressive ones. The doomer/accelerationist schism. The Taoist farmer's reply. And why both tribes are losing to the exact same trick.
