Geoffrey Huntley, who himself built Amp coding agent at Sourcegraph, has released a hands-on workshop that strips away the mystery and teaches you to build your own AI coding agent from scratch. The secret? Five core primitives that every coding agent uses: read files, list directories, execute bash commands, edit files, and search code with ripgrep. That's it.

Cohere just released Command A Reasoning, a 111B-parameter reasoning model purpose-built for tool use, agentic, and multilingual use cases in enterprises. The model can be used both with reasoning on or off, and runs on a single H100/A100 GPU with 128K context (or 256K on multi-GPU setups).

Last week, YC held one of the biggest AI agent hackathons. While everyone focused on building AI products from scratch, this group of developers took an interesting idea to spin: running Claude Code headlessly in a loop forever and see what happens. The result is RepoMirror, a surprisingly effective AI tool that transforms entire code repositories from one technology stack completely autonomously

Always start with a technical design document, as this is where the bulk of the work happens. Design review before launching into the development effort, and backlog development and sprint planning. Use Test Driven Development, and have a dev approval process before code can get merged into main. Test in staging before pushing to production.

Here’s how it works:

  1. Take our questionnaire and get matched with a therapist.

  2. Schedule a time to meet and communicate on your terms.

  3. Reach out to your therapist anytime, from anywhere.

The plan starts with the iPhone Air, a skinny new model that follows the MacBook Air laptop strategy. Apple's first foldable iPhone will arrive in 2026

Meta researchers have found a new use for photonic integrated circuits (PICs), chips that can receive, modulate, and direct light. Their PICs can receive RGB light from laser light sources integrated into a panel, process it, then shine light onto a liquid crystal on a silicon panel for final display. The overall complex is just two millimeters thick and has a dramatically better color gamut over similar displays.

Meta FAIR researchers released DeepConf, a method of deep thinking that achieved 99.9% on the AIME benchmark using open-source models. It leverages model-internal confidence signals to dynamically filter low-quality reasoning traces during or after generation.

A reverse mortgage can be a smart way for older homeowners to fund home improvement projects – especially upgrades that make aging in place safer and more comfortable.
