Grok Build, or the Day the CLI Became a Standard
xAI shipped Grok Build this week — same AGENTS.md, same MCP, same Skills, same plugins, same hooks. The interface just became a standard. The war moves to the model.

Codex Mobile, About a Release Quarter Late
OpenAI shipped Codex inside the ChatGPT mobile app, about a release quarter after Anthropic's Claude Code Remote. The surface caught up fast. The execution boundary is where the real argument lives.
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.
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.
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.

Yes, Opus 4.7 Sucks. Signed, Opus 4.7.
Claude Opus 4.7 shipped April 18, 2026. Within 48 hours, Reddit had a 2,300-upvote regression thread. Within 5 days, Anthropic published a public postmortem. Here are the receipts: GitHub issue #50235, the AUP cop, the tokenizer tax, and what's actually better.

Two Magnets and a Nose: First Hit With Intake Breathing
Years of nasal-spray rebound turned me into a chronic mouth breather. Then a $60 box with two magnets showed up — and 30 seconds later I was breathing through my nose for the first time in a decade.

Fútbol en Medellín
Otro día con densidad. Empezó con cansancio post-gripe — siesta, recalibración biohacker (ahora con NAD+ split protocol), y el cuerpo respondiendo. Fútbol con los hijos en la tarde, cierre en Bárbaro Cocina Primitiva, Cohiba en la noche. Cuando agarras buena ola, no paras.
Craft
HIPAA for Software Engineers
From zero to HIPAA-compliant: a builder's guide that starts ELI5 and progresses to architecture decisions. Covered entities, BAAs, ePHI, encryption, audit logs, AWS/GCP/Azure HIPAA-eligible services, breach notification, and the 2025 NPRM that turns 'addressable' into 'required.'
AI
Sinapt and the Queryable Company
275+ SaaS apps per enterprise. 40-60% of RAG never ships. Your knowledge is everywhere and queryable nowhere. Every AI agent rebuilds context from scratch. Companies that win the AI era will stop paying the knowledge tax. Sinapt is the bet on how.

Claude Killed the API Key
Anthropic just shipped Workload Identity Federation for the Claude Platform — short-lived OIDC tokens via AWS, GCP, Azure, or any standards-compliant IdP. Production AI auth finally graduates from "static API key in .env" to first-class cloud workload.
Life
MMA Colombia
Un día en Medellín con la densidad que tiene este país cuando sale al ataque. Recalibración biohacker, Adidas con los hijos, gimnasio brutal, primera clase de MMA juntos en MMA Colombia con David, cierre en La Causa. La vida que se construye cuando nadie está mirando.

La Causa
Llevo años yendo. Es de los pocos restaurantes que no me salto en una semana. Una carta de amor a la cocina Nikkei, a Lima y a Kioto, y a un emoji de sushi que mi hija de 11 años me manda cada que tiene antojo.

Claude's Constitution
Anthropic published a 23,000-word values manifesto for Claude under CC0. The four-principle priority order, the Aristotelian framing, and what every operator should internalize before their next session.

Memory Outside the Tree
The symlink trick from The Exomind looked clean — versioned memory in the repo, portable via git. It also broke autonomous operation. The fix: reverse the symlink and let the kernel resolve the path before the protected-path check sees it.

Sinapt: Two Products, Not One
Slept on yesterday's Sinapt brainstorm. Woke up with one sharp correction: it's not one product, it's two. The knowledge-base infrastructure ships first; the cockpit is a future opinionated layer on top.
