What a $57 Billion Chart Is Actually Counting

A friend sent me a screenshot of a "Total RWA Value" chart at $57.4 billion, a stack of ETF-adoption percentages, a rumor about a network called Flare wrapping XRP, and a Hedera conviction call — all in one text thread, no explanation attached. So I went and found out what each piece actually is: wh

XRP, Basel, and the 1,250 Percent Number

A video making the rounds walks through a real trend — stock exchanges tokenizing shares — then pivots to Basel I, II and III, and lands on a specific claim: the newest paper out of Basel mentions XRP dozens of times, therefore the Bank for International Settlements is about to use it. The paper is

Eleven Votes Short of Clarity

The Senate held a cloture vote today on the CLARITY Act, the bill meant to finally tell crypto exchanges which regulator they answer to. Forty-nine senators voted yes, fifty voted no, and the rule requires sixty. Bitcoin slid through the session as the vote failed. Here is what the bill would have d

Mining

One Watt a Terahash, and the Math It Skips

A real mining-hardware company tweeted this week that it built a Bitcoin miner out of a fruit fly's brain, claiming ten times the efficiency of the best silicon ASIC on the market. The neuron map behind it is genuinely new science, released this month. The miner is one tweet, no paper, no repository

The Same Barrel

Costco started rationing motor oil this week, a first in its history — two boxes of its own Kirkland Signature synthetic per member, per week. Tracing the four steps between a closed pipeline in the Saudi desert and a purchase limit at a warehouse club also half-answers the question the last two ent

What a Locked iPhone Still Gives Up

A phone-forensics demonstration circulating on X this week is a reminder that "only law enforcement has this" was never really the boundary — the tools, the vendors and the exploits all move. What a locked iPhone actually protects, what Advanced Data Protection does and doesn't cover, and a short hi

A Rate Hike Against a Strait

On Friday the inflation number came in at 3.4 percent and the futures market moved to better than 85 percent odds that the Federal Reserve raises interest rates next Wednesday. Take energy out of that 3.4 and it reads 2.4 — a whisker from the target. So the Fed is about to raise the price of money i

Eight Years to Mercury, and One Chance to Stop

On 3 September the BepiColombo spacecraft, two hundred million kilometres from Earth, let go of the engine that carried it for eight years and 9.9 billion kilometres. On 21 November it has to stop at Mercury, the hardest planet in the solar system to arrive at, using a sequence it will run on its ow

Escape, and the Four Times I Paid for It

The second entry in my Journey series is the record that got me — Escape, July 1981, the first with Jonathan Cain, the one with "Don't Stop Believin'" on it. It came to me off the radio, and then I bought it on LP, and then on cassette, and then on CD, and then took it for free on Napster like every

Galileo's Experiment, Done With One Atom in Two Places

A team including Roger Penrose has dropped a rubidium atom that was, in the quantum sense, in two places at once — one half falling freely, the other held still — and read off how gravity changed it. Einstein's equivalence principle survived. What makes it worth an entry is not the result but the la

Not Available on This Connection

Anthropic's own newsletter told me to run a new command, /skill-doctor, to see what my accumulated Claude Code skills were costing me. It failed three times, and once, when it printed the true reason why, the assistant's own reply talked past it. The fourth try stopped refusing the connection and ga

Raised on Radio, the One I Have to Defend

My favorite Journey album is not Escape and not Frontiers. It's Raised on Radio, from 1986 — the one Steve Perry produced himself, the one made after two founding members were let go, the one the band never quite recovered from. This is the entry where I say why: it was mostly Perry, it mixed his vo

The Other Door

Yesterday I wrote that the East–West pipeline was Saudi Arabia's escape valve around a closed Strait of Hormuz. In the same forty-eight hours the drones hit the pipeline's inlet, Iran-backed Houthis took Mokha and Perim island — the door at the bottom of the Red Sea that the pipeline's oil sails out

The Second Plane

Twenty-five years ago I was woken up in California to watch the second plane go into the tower. This week 2,977 drones rose over New York Harbor, one for each person, and built the towers again for a few minutes at full size. It got to me more than I expected, and I've been trying to work out why —

The Week the AI Labs Asked to Be Regulated

In one week in September 2026: OpenAI shipped a model its president called the start of the AGI era, then asked Congress for mandatory safety rules it had spent two years opposing; it put its most prominent internal critic on the board, and he said the industry was not on track; Anthropic published

Why Journey

My favorite band, of all time, is Journey. This is the first entry of a series about them — not a history of the band, which exists already and was written by people who were in the room, but one record at a time, each paired with where I was when it reached me. It starts with why, with the singer w
