ELON MUSK'S NEURALINK JOINS STUDY WORKING TOWARD A BIONIC EYE

Neuralink is collaborating with researchers in California and Spain on a clinical trial to study visual prosthetics. The study, sponsored by the University of California at Santa Barbara, aims to address the fundamental questions that will allow the development of a Smart Bionic Eye. Such a device would use AI to help blind people identify faces, navigate the outdoors, and read, among other things. The study's description says that researchers will use Neuralink patients 'once available'. Neuralink is developing a brainchip called Blindsight that aims to restore vision to blind people and grant superhuman vision.

HOW WE ROOTED COPILOT

Eye Security researchers discovered a vulnerability in Microsoft's Copilot Enterprise that allowed code execution in a live Python sandbox. By exploiting the ability to run Jupyter Notebook commands, they got root access within the container by poisoning the `pgrep` command, but found limited ways to use this privilege due to security mitigations. They reported the issue to Microsoft, which fixed it as a moderate-severity vulnerability, and were acknowledged for their research.

AN ENGINEER'S GUIDE TO AI CODE MODEL EVALS

A crucial part of the process of improving a coding-capable AI model is evaluation (evals). Evals are structured tests or benchmarks used to measure model performance on specific tasks. They are analogous to unit tests or integration tests in software. This post explores what evals are, how they're constructed, what 'hill climbing' means in model development, and how all these pieces connect to the continuous training and improvement of coding models.
