Wordsworth's Open Letter Supporting Copyright Reform

In 1838, William Wordsworth penned a powerful letter to Serjeant Talfourd, MP, voicing his staunch support for a bill aimed at reforming copyright law. Faced with significant opposition from printers and publishers, Wordsworth declined to petition Parliament, instead choosing to publicly declare his belief in authors' inherent right to perpetual ownership of their works—a right far exceeding the bill's proposed term. He argued this right stemmed from common law and criticized opponents for hiding behind existing statutes, avoiding a defense of this fundamental right. The letter also touches upon his concerns for literary giants like Coleridge, Scott, and Southey, expressing his deep respect and gratitude for Talfourd's efforts.

AI Moats: Data, UX, and Integration, Not Models

Last year, we argued that AI wasn't a moat, as prompt engineering is easily replicated. However, models like DeepSeek R1 and o3-mini have reignited concerns. This article argues that better models are a rising tide lifting all boats. Sustainable competitive advantages lie in: 1. Exceptional user experience—focus on seamless integration into workflows and solving user problems, not just adding AI for the sake of it; 2. Deep integration with existing workflows—integrate with messaging, document systems, etc.; 3. Effective data collection and utilization—focus on both input and output data for insights and improvements. Ultimately, AI is a tool; the key is understanding and meeting user needs effectively.

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.

Bypassing Disk Encryption with Automatic TPM2 Unlock: A Critical Vulnerability

2025-01-17

This article exposes a critical vulnerability in systems using TPM2 for automatic disk encryption unlocking. An attacker with brief physical access can decrypt the disk without altering the TPM's state. The vulnerability stems from most setups failing to verify the LUKS identity of the decrypted partition. The attacker can use the initrd image in the unencrypted boot partition to create a fake LUKS partition with a known key, tricking the system into executing a malicious init program, thereby obtaining the original disk key. Solutions include using a TPM PIN or properly verifying the LUKS identity within the initrd.

Tensor Product Attention: All You Need

Tensor Product Attention: All You Need

Scaling language models to handle longer input sequences typically requires large key-value (KV) caches, resulting in substantial memory overhead during inference. This paper proposes Tensor Product Attention (TPA), a novel attention mechanism that uses tensor decompositions to represent queries, keys, and values compactly, significantly reducing KV cache size during inference. By factorizing these representations into contextual low-rank components (contextual factorization) and seamlessly integrating with RoPE, TPA improves model quality while maintaining memory efficiency. Based on TPA, the authors introduce the Tensor ProducT ATTenTion Transformer (T6), a new model architecture for sequence modeling. Extensive empirical evaluation on language modeling tasks demonstrates that T6 surpasses standard Transformer baselines including MHA, MQA, GQA, and MLA across various metrics, including perplexity and a range of well-known evaluation benchmarks. Notably, TPA's memory efficiency enables the processing of significantly longer sequences under fixed resource constraints, addressing a critical scalability challenge in modern language models. Code is available.
