Judge Allows Nationwide Class Action Against Anthropic Over Alleged Piracy of 7 Million Books For AI Training

2 weeks 4 days ago
A California federal judge has ruled that three authors suing Anthropic for copyright infringement can represent writers nationwide whose books the AI startup allegedly pirated to train its Claude chatbot. U.S. District Judge William Alsup said the authors can bring a class action on behalf of all U.S. writers whose works Anthropic allegedly downloaded from pirate libraries LibGen and PiLiMi to create a repository of millions of books in 2021 and 2022. Alsup said Anthropic may have illegally downloaded as many as 7 million books from the pirate websites, which could make it liable for billions of dollars in damages if the authors' case succeeds.

Unplugged and Unstoppable: How Linux Transforms Laptop Power Management

2 weeks 4 days ago
by George Whittaker Driving Forces Behind Smarter Battery Use

In an era when remote work, video conferencing, and travel-heavy lifestyles are the norm, users expect laptops to last longer unplugged. Meanwhile, growing awareness of sustainability adds pressure to maximize energy efficiency. Recognizing this mantra, Linux developers have overhauled power-handling strategies, from the kernel core to user-space tools, to meet these expectations in 2025.

Core Kernel Enhancements: Harnessing Modern Power Tech Kernel 6.x’s Focus on Power Efficiency
  • Linux 6.8 introduced refined support for newer hardware, including better CPU/GPU idle-state transitions and energy-friendly firmware interfaces.

  • Linux 6.15, released in May 2025, continues this trend by adding improved power-capping, more regulators, voltage handlers, and enhanced support for ARM, RISC-V, and Intel/AMD CPU power modules.

These enhancements enable finer-grained control over sleep states, clock gating, and dynamic walling-off of unused chip domains, all pivotal for squeezing extra runtime.

MCU-Firmware Communication with FWCTL

A new firmware controller (fwctl) infrastructure within 6.15 gives user-space tools secure communication channels with embedded controller features, making tasks like adjusting battery charge thresholds more accessible and scriptable.

Advanced CPU & GPU Power Strategies Smarter Frequency Governors

Both intel_pstate and amd_pstate drivers continue evolving. Passive and conservative CPU governors now dynamically adapt based on workload profiles, delivering noticeable battery gains with minimal performance loss.

Low-Power On-Battery GPU Modes

Graphics subsystems are smarter about sleep:

  • Intel's Arc and DG2 families now feature improved idle ramp-down behaviors for better battery performance.

  • For AMD users, the transition from generic AMDGPU RADEON_POWER_PROFILE settings to fwctl-control offers more granular DPM tuning on laptops, especially under battery constraints.

Deep Sleep States and ACPI Evolution

The adoption of ACPI 6.6 and expanded kernel support for S0ix and modern-sleep states allow laptops to hang out in ultra-low-power standby, extending idle time battery life. Suspend-to-disk and resume logic also got less noisy, reducing spur-of-the-moment wake-ups that were draining battery life for many users.
