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.
Your Sessions Can Talk. The Design Is in the Refusals.
Anthropic shipped cross-session messaging as a convenience feature: stop re-explaining yourself in the other terminal. What actually shipped is an addressable peer network with its own threat model already written into the product, and the engineering worth reading is all in what a session refuses.
The Deficit Beat the Peptides
The number I was most afraid of was already over the line before I injected anything. Ninety-eight days and three blood panels later it came back down, and not because of the drugs. Every marker, baseline against now, plus the six answers I still do not have.

The Expensive Part Is Remembering
I burned a month of allowance in five days, so I measured where every token went. Almost all of it is the agent re-reading what it had already seen. Every meter Claude and Codex run, which multiplier owns which share of the bill, and each fix priced against the real distribution.

One Hour, Door to Door
In Colombia you wait for everything. Today my son needed a doctor and the whole thing — transport, consultation, medicine, home again — took sixty minutes.

Bring The Pain
Thirteen working sets moved as much weight as twenty-six did. Day 2 of the block, logged — and a 240 kg leg press that resets the top of the board.

The Human Is Not the Runtime
We made the most dangerous module in the system harder to change, and throughput did not move. The gate got stricter. The humans just stopped being the thing it runs on.

Thirteen Tonnes and a Clean Heart
One result is back from the panel and it is the good one: two ECGs, 104 days apart, and every number that matters is where it was. Then day one of the new block put thirteen tonnes on the board and made me sore in twelve hours.

265,000 Stars and I Don't Use Any of It
A friend sent me obra/superpowers. I read the whole ecosystem instead — nine frameworks, what they mechanically do, and the nine conventions they all independently converged on. Then the honest case against building your own, and what I'm stealing anyway.

Meta Ray-Ban Display: $799, One Eye, and a Wristband That Reads Your Nerves

These Are the Final Results. Nooot.
Testosterone up 56% measured at its floor. Estradiol up 215%. And six iron markers leaning the same way, which is the finding nobody would have flagged. Then, hours after the PDF landed, a message that made the word final premature.

The Sword Goes Back in the Sheath
Pushing through when you're tired is half a rule. The other half is stopping deliberately, at a moment you chose. A weekend in the Eje Cafetero, a clinic that took ownership when it didn't have to, a product going live, and the only test of a system that counts.
