Turning a dumb AC unit smart (without losing my security deposit)

https://prilik.com/blog/assets/automating-ac-nyc/aircon-controls-crop.jpg
A DIY home automation project was created using a stepper motor, ESP32, and a high-tolerance for "jank" to control a rental apartment's AC unit with analog knob-based controls. The project was successfully integrated with Home Assistant using MQTT, allowing for automated temperature control and saving a non-trivial amount of money on electricity bills.

Handbook.md shows that long policy documents do not reliably govern agents

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Researchers created a benchmark of 65 tasks to test language-model agents following long policy documents. The benchmark, which simulates real-world work environments, found most agents failed to consistently follow policies due to issues like overriding rules and losing details over time.

Commodification of Intelligence: Good, Bad, and Ugly Circular AI Deals

https://www.emergingtrajectories.com/assets/677d5ee3d185dd5dede0a75e/67a0d0ade0b78706efd6a5d8_heropink.png
The AI industry is evolving to commodify AI, making compute capacity a fungible commodity like electricity, with circular deals enabling companies to access necessary resources. These deals, common in traditional commodities markets, help companies like startups and hyperscalers access capital and resources, but can become risky if overextended or hidden from investors.

How much can you delegate to agents?

https://substackcdn.com/image/fetch/$s_!HnV9!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fb8188004-4403-4b09-87ed-29462aed3aa1_1600x828.png
To decide when to trust agents, you need to build a mental model for delegating tasks based on their checkability and reversibility. This involves creating a decision tree with four levels of agent autonomy: assistant, human-in-the-loop, delegation, and self-driving mode.
