When the Cincinnati Post shut down, it oddly had an effect on local elections. Fewer people ran for office, voter turnout fell, and incumbents became more likely to win. That's useful context for Trump's choice to ban 3 news orgs from the White House newsletter.platypuseconomics.com/p/what-econo...

One cool thing about #AI-assisted software development is that I can use my software “in the field” and, when I encounter functional gaps, address them immediately—without having to endure much context switching. The speed at which you can round-trip between using the software and improving it is 🔥.

GTG-87001: Disrupting a Yemen-based guided weapons engineering cell using Claude to develop guidance software
Summary

We identified a cell of threat actors based in northern Yemen running three weapons development programs: a guided rocket that used a commodity phone-class flight computer with final-phase homing guidance; a multi-stage ballistic missile with a stated range goal above 2,000 km; and a multi-variant missile (referred to as the “R2000” set) that included a hypersonic glide vehicle variant.

The actors used Claude Code in place of human software engineers to develop the guidance, navigation, and control (GNC) software that steers and stabilizes a flying vehicle. For example, they used Claude to integrate an open-source autopilot onto a phone-class flight computer, writing the control and position estimation software, tuning the control settings, running a firmware build pipeline, and performing a flight simulation. The actors managed several Claude instances at once, assigning each one a role, much as a lead would delegate work on a small engineering team: the actors tasked one instance with writing the code, another with research, and a third with reviewing the code the first instance produced.

Our safeguards blocked many of their requests, but not all of them. The actors used a variety of tactics to evade our safeguards, including hiding their goals and the products the software was meant for, and they split their work across multiple sessions so no single session revealed their full intent.

These actors carried out a sustained effort to develop guided weapons, including using Claude to design guidance software. We do not have evidence the actors succeeded in fielding an operational device; but they did test-fire a guided rocket. This field test appears to have failed: within hours, the actors returned to Claude to work out why it failed.

We identified this activity as part of our internal investigations into suspected weapons development. We banne…

The sucky #EV infrastructure in #Hawaii really stings during widespread power outages, when home charging isn’t an option for many. Only 4 fast chargers on the entire west-side of the #BigIsland. None faster than 62 kW (entire island). I found a working quality 6.5 kW charger at the #Kona #Target 🤡.
Close-up of a damaged electric vehicle charging cable attached to a dark gray car. The thick black handle has a torn strain relief with white fibers sticking out and exposed inner wires in bright green and turquoise. Part of the car’s alloy wheel with silver spokes and some dirt is visible, along with asphalt ground and a small red reflector. Dominant colors are black, dark gray, and silver with accents of green and blue. The weather appears overcast and dry.

Just in time for hurricane #Lala I joined the #CoCoRaHS network to do some citizen #science 🤙 and installed a #TROPO Precipitation Gauge ⛈️. The data is e.g. used by the the National Weather Service (NWS). My station is HI-HI-121, currently the only active CoCoRaHS rain gauge in #Holualoa #Hawaii.
The image is a screenshot of a weather-station dashboard titled “HI-HI-121: Holualoa 2.0 NW,” dated Aug 14, 2026. The layout is clean with a white background, light gray panels, blue icons and accents, and black text—blue and gray are the dominant colors. At the top it shows “Station Overview.” A “Recent Precip Accumulations” box displays three rain‑gauge graphics with small blue fills. Readouts state Today: 0.08", Month‑to‑Date: 0.08" (1 of 14 days covered), and Year‑to‑Date: 0.08" (1 of 226 days covered). Below, “Station Activity” lists Period of Record: Aug 14, 2026 – Aug 14, 2026, Pct of Days covered by Precip Obs: 100%. Observation counts show Daily Precip 1, Multi‑day Precip 0, Condition Monitoring 0, Significant Weather 0, Hail 0, and Total Obs 1. Overall, the weather indicated is a light rainfall amount recorded today (0.08 inches), with no hail or significant weather reported.
