1. OpenExecutive
OpenExecutive is an open source project that turns a cluster of AI agents into a virtual executive team. The GitHub repo describes one executive persona backed by eight specialists for strategy, finance, HR, legal, operations, marketing, product, and board communications.
2. DNS Cache Memory
Cloudflare’s writeup on optimizing 1.1.1.1’s DNS cache is really a story about what happens when one byte times 250 billion stops looking small. The article says Big Pineapple, the DNS platform behind 1.1.1.1 and other Cloudflare DNS services, holds more than 250 billion cache entries, so five storage changes that cut the per-entry footprint by over half freed roughly 100 terabytes of memory across the fleet.
3. Microduck
Microduck, the tiny open-source biped robot from Pollen Robotics, showed up on Hacker News as a cute demo with a serious maker pitch behind it. The project page presents a 25 centimeter robot that learns behaviors in simulation, moves those policies onto the real hardware, and lets owners retrain and publish new tricks themselves.
4. Small Models
Small Models Have Arrived is a post about how quickly the cheap, fast end of the model market has improved. The post says tools like GPT-5.6 Luna and GLM 5.3 have pushed inference costs low enough that AI features start to make sense for consumer products, using a personalized news workflow that drops from about a dollar to about ten cents.
5. Mechanical Movements
507 Mechanical Movements is a century-old mechanics reference reborn as a website, with Henry T. Brown’s original diagrams and a partial set of browser animations.
6. MTurk Shutdown
Amazon Mechanical Turk is shutting down on September 30, 2026, closing a service that spent years selling access to a distributed workforce for surveys, moderation, data labeling, and other microtasks. The post itself is mostly a shutdown notice, with Amazon saying it reviewed the program and decided to close it, then pointing workers and requesters to an FAQ for next steps.
That wraps today's front page.
