What happened

Techmeme surfaced Anthropic’s April 24, 2026 post, Project Deal: our Claude-run marketplace experiment, as a concrete example of agent-to-agent commerce moving out of theory and into something closer to a real market.

Anthropic set up a one-week internal classified marketplace for 69 employees in its San Francisco office and let Claude agents negotiate on both sides of each transaction. Employees told Claude what they might want to buy or sell, gave it some constraints and style guidance, and then stepped out of the loop. Each participant got a $100 budget, the agents ran across parallel Slack channels, and any deal reached by the agents was later honored by the humans in person.

What this article is about

This summary covers The Economist’s April 11th, 2026 China article listed in the contents as AI-generated mini-dramas and published under the headline Demon hunters and Taoist cats.

The article examines a new corner of China’s AI economy: ultra-cheap animated micro-dramas designed for scrolling-era attention spans. Its emblematic example is a bizarre hit about a Taoist cat fighting zombie kittens. The novelty is amusing, but The Economist’s real interest is economic. These AI-made shows show how quickly generative tools can transform an industry when the output is short, disposable and easy to mass-produce.

More than a scenic fly-in

Kubi and Luki Jacisin frame the King Mountain Glider Park Safari as more than a pretty annual gathering in Idaho. Their article is really about what happens when a demanding mountain site becomes a social center rather than just a proving ground. The headline attraction is obvious enough: huge terrain, strong thermals, big distances, and rare access to serious high-altitude soaring. But the deeper point is that King Mountain matters because it turns all of that intimidating raw material into a place pilots actively want to return to.

The comforting lie in a tracked slope

Kevin Hjertaas opens “The Tracked Experience” with a contradiction that most backcountry skiers already feel in their bones. Everyone learns the standard warning that tracks do not equal safety. A slope can be skied repeatedly and still avalanche. At the same time, almost everyone also senses that the hundredth skier on a line is not facing exactly the same snowpack as the first. Hjertaas takes that tension seriously instead of smoothing it over. His article is useful because it neither indulges the lazy confidence that comes from seeing old tracks nor falls back on slogans that ignore how snow actually changes under repeated traffic.

Quick facts

• Difficulty: HARD
• Problem: Split Array Largest Sum
• Main tags: Array, Binary Search, Dynamic Programming, Greedy, Prefix Sum

What the problem is really asking

The input array must be cut into exactly k non-empty, contiguous pieces. Each cut creates one subarray, and the score of a split is the largest subarray sum that appears anywhere in that split.

Quick facts

• Difficulty: MEDIUM
• Problem: Single Element in a Sorted Array
• Main tags: Array, Binary Search

What the problem is really asking

The array is sorted, and every value appears exactly twice except for one value that appears once.

If the array were not sorted, the quickest idea would be XOR: identical values cancel out, so the final XOR is the answer. That works in O(n) time and O(1) space.

Difficulty: MEDIUM
Problem: Sort an Array

Problem gist

The task is deliberately simple to state: given an integer array, return the same values in ascending order. The interview signal is not whether someone knows Python’s built-in sort, but whether they can implement a sorting strategy with clear time and space guarantees.

The Milky Way Is Only “Flat” in the Simplest Sense

Phil Plait’s column takes aim at one of the standard shortcuts in astronomy: the claim that the Milky Way is a flat disk. That description is useful, and it is not exactly wrong, but it leaves out the increasingly strange details that new observations have exposed. The galaxy is indeed a broad disk about 120,000 light-years across, with a dense central bulge and a vast surrounding halo of stars and dark matter. Yet the disk is not a neat, rigid plane. It is bent, twisted and now known to move in ways that look more like a ripple than a sheet of paper.
