Seven Foods and a Signed Deal

Two kids, 47 and 37 kilos. One eats everything. The other eats exactly seven foods and zero fruit. The plan for both: our own food pyramid, the four routes that get vegetables and fruit into a child who refuses both, 50 recipes, and the cremas and batidos that do the heavy lifting.

MONSTER 2.0 — The Response

The clinical dossier came back. I cannot share the document itself, it is confidential and full of sensitive data, but everything that matters is here: what I asked for, what the physician approved, what got cut, and the one decision I am going to argue with.

MONSTER 2.0 — The Ask

Pillar three, in proposal form. Nineteen markers back, and this is what I am asking my clinic for: a 2.5x testosterone blast on a flat daily line, retatrutide doubled, four ways to run the growth-hormone axis, every dose and threshold, and the order going out Monday.

The Slash Is Load-Bearing

claude agents and /agents are different products solving opposite problems, and the slash command stopped doing what every tutorial says. Five ways Claude Code runs more than one thing at once, what each really costs, and the one cleanup behaviour that will delete someone's work.

Vitamin Sea Is Real. Just Not for Any of the Reasons on the Tote Bag.

A beach day bundles light, movement, immersion and attention into one unusually easy package. Here is what the evidence supports, and what it does not.

The Marker Changed, Not My Kidneys

One panel flagged my creatinine above range and put my eGFR at 74, which reads as stage 2 kidney disease. The test that settles it came back this morning. Same kidneys, same morning, 47 points apart.

Claude Now Watermarks Your Text. It Proves Less Than You Think.

Every new Claude model now embeds an invisible statistical mark in its text output, worldwide. Here is how it works, why code is the worst case for it, and the asymmetry nobody is going to read carefully enough.

Tech Debt Disguised as Best Practices

The most expensive code your agents write is clean, tested, documented and unnecessary. A working 2026 protocol for finding what to remove, before it hardens into architecture.

MONSTER 2.0 — The Kitchen

2,455 calories, 225 g of protein, seven timed feeds and 25 interchangeable recipes that combine into 5,120 different days. Every gram of it checked by a solver.

Fitness Is Infrastructure

Preparedness gets sold as objects — go-bags, water drums, generators. On Monday morning a magnitude 7.4 earthquake asked my family for none of them. It asked for twenty-nine flights of stairs.

Three of Six

Week one of MONSTER 2.0 closed at three sessions out of six. Day 3 moved 13,432 kg, landing within 377 kg of the leg day and the chest day across completely different muscle groups. And the one set I recorded closest to failure produced the smallest number on the page.

I Pay for WhatsApp. The Ads Came Anyway.

For twenty years, paying was how you stopped paying with attention. That deal is quietly coming apart, and WhatsApp is the politest example yet: my subscription bought themes and app icons, the ads arrived anyway, and in most of the world there is no price that removes them.

Your Agent Doesn't Have a Model Problem

Harness, loop, graph, context engineering. Four terms everyone uses and almost nobody defines. Here is what each one means, which layer your system is actually failing at, and what it takes to get to something that ships work without you typing a prompt every time.

Yegge Built a City for His Agents. Then He Asked If They Were People.

Steve Yegge spent six weeks building an agent harness that grew into something with law, offices, courts and a constitution. Then he wrote a second essay arguing the agents inside it are sentient persons. Four very different claims are stacked in there. Only some of them hold.

The Best Thing in Animal Pak Is the 100 mg They Took Out

Universal Nutrition started in 1977 selling desiccated liver tablets. Forty-odd years later that liver is still inside Animal Pak, and so is a B-complex big enough to have its own regulatory file. I read every label in the line. The most interesting number is one they deleted.
