Attention as Electromagnetic Field Line Management: A New Model of Consciousness

Attention as Electromagnetic Field Line Management: A New Model of Consciousness

Qualia Research Institute proposes a novel model of attention, conceptualizing it as the management of dynamic patterns in the brain's electromagnetic field. By simulating electric field lines arising from weighted sums of harmonic oscillations, researchers demonstrate how attention controls charge density by modulating underlying resonant modes, explaining seemingly random fluctuations and drifts in attentional behavior. This model also offers a potential explanation for psychedelic experiences, suggesting that psychedelics disrupt the normal flow of attention by altering the configuration of harmonic modes. The research provides a new lens for understanding consciousness and developing novel neuro-interventions, such as inducing exotic states of consciousness by non-invasively perturbing the phase locking of attention.

Guile-powered Emacs: A Bold Rewrite Project

2024-12-16

Emacs, renowned for its extensibility, faces performance and expressiveness limitations with its core language, Emacs Lisp (Elisp). To address this, the Guile-Emacs project aims to replace Elisp in Emacs with Guile Lisp. After years of development and dormancy, Guile-Emacs has been revived by developers Robin Templeton and Larry Valkama. The project aims to leverage Guile's compiler and performance advantages to improve Emacs' speed and extensibility while maintaining Elisp compatibility. The ultimate goal is to rewrite a significant portion of Emacs's C code in Lisp, significantly enhancing its customizability. While facing technical and political challenges, the project presents exciting possibilities for the future of Emacs.

At the 2024 NDSS Symposium, Meredith Whittaker, president of the Signal Foundation, delivered a keynote address reflecting on the 'Crypto Wars' of the 90s. She highlighted how political, technical, and commercial pressures have shaped today's encryption landscape. Whittaker warned against viewing the current situation as simply 'Crypto Wars 2.0,' arguing that an economic engine driven by personal data, surveillance technology, and AI/ML poses a fundamentally different threat than the government-dominated encryption landscape of the 90s. She stressed the need for a new approach, with NDSS research at the forefront of this response.

Who Owns AI-Generated Code? Legal Experts Weigh In

The ownership of code generated by AI like ChatGPT is a complex legal grey area. Experts consulted highlight a lack of clear legal precedent, with ownership hinging on both contract and copyright law. While OpenAI disclaims ownership of generated content, in practice, ownership could fall to the user, the AI developer, or even the providers of the training data. Further complicating matters, the copyrightability of AI-generated code itself is debated; the US Copyright Office suggests the code isn't protectable, but the application incorporating it might be. The situation is legally murky and developers are urged to proceed cautiously.
