AI Boosts Gravitational Wave Detection: Deep Loop Shaping Breakthrough

Scientists have used a deep learning technique called Deep Loop Shaping to significantly improve the control precision of the Laser Interferometer Gravitational-Wave Observatory (LIGO), reducing noise by up to 100 times. This technology, using reinforcement learning, optimizes LIGO's feedback control system, enabling it to measure gravitational waves more stably. This helps astronomers delve deeper into the dynamics and formation of the universe, such as detecting more intermediate-mass black holes and studying neutron star collisions in greater detail. This breakthrough is expected to influence the design of future gravitational wave observatories and further expand our understanding of the cosmos.

Reverse Engineering The Incredibles: Rise of the Underminer for Speedrunning Optimization

2025-05-03

To optimize their speedrun of The Incredibles: Rise of the Underminer, the author and his brother reverse-engineered and modded the GameCube game. They discovered debug features and out-of-bounds glitches, and statically reverse-engineered the combat system code using Ghidra. To experiment more easily, they created a mod that displays enemy health, applying it via Action Replay codes. This revealed interesting damage information, such as Mr. Incredible's punches doubling in damage with successive hits and higher damage against frozen enemies. They also explained why some known cheat codes were invalid, needing developer mode to work. Finally, the author shared some out-of-bounds glitches and developer mode features like flight and debug overlays.

Broadcom's VMware Audits Spark Controversy: Customers Question Aggressive Tactics

Following its $69 billion acquisition of VMware, Broadcom's aggressive license compliance reviews are sparking controversy. Broadcom has sent cease-and-desist letters and audit notices to numerous companies, but several firms deny wrongdoing, claiming they only installed security patches or no longer use VMware at all. This has led to potential financial repercussions for some companies, including possible layoffs. Broadcom's strong-arm tactics have damaged its image and prompted calls for regulation of its business practices.

One-Minute Videos from Text Storyboards using Test-Time Training Transformers

2025-04-08

Current Transformer models struggle with generating one-minute videos due to the inefficiency of self-attention layers for long contexts. This paper explores Test-Time Training (TTT) layers, whose hidden states are themselves neural networks, offering greater expressiveness. Adding TTT layers to a pre-trained Transformer allows for the generation of one-minute videos from text storyboards. Experiments using a Tom and Jerry cartoon dataset show that TTT layers significantly improve video coherence and storytelling compared to baselines like Mamba 2 and Gated DeltaNet, achieving a 34 Elo point advantage in human evaluation. While artifacts remain, likely due to limitations of the 5B parameter model, this work demonstrates a promising approach scalable to longer videos and more complex narratives.

Ford Mach-E Outsells Gas-Powered Mustang for the First Time

In 2024, Ford's electric Mustang Mach-E outsold its gas-powered counterpart for the first time, solidifying its position as a top-selling EV in the US. All of Ford's EV models achieved record sales in 2024, showing double-digit growth. The Mach-E's strong performance, with 16,119 units sold in Q4 and 51,745 for the full year, places it as the second best-selling electric SUV in the US, only behind the Tesla Model Y. Meanwhile, sales of the gas-powered Mustang declined by 9.5% to just over 48,600 units. This significant milestone highlights the increasing consumer preference for electric vehicles and the rapid growth of the EV market.

Beyond Autoregressive Models: The Next Frontier in AI

2025-03-07

Most generative AI models today are autoregressive, meaning they predict the next token, with the transformer architecture being the dominant implementation due to its computational efficiency. However, autoregressive models have inherent limitations, such as a lack of planning and reasoning capabilities, limited long-term memory, and a tendency to "hallucinate." The author argues that human thought isn't purely autoregressive, encompassing non-sequential thinking and planning. To achieve AI closer to human cognition, researchers are exploring alternative paradigms like JEPA and diffusion models, which generate content through iterative refinement or denoising from noise, mirroring human thought processes more closely.

India's IT Sector: An AI-Driven Exodus

India's $250 billion technology services industry, built on a foundation of low-cost engineering graduates, faces a structural crisis. AI is rapidly automating entry-level roles, the very training ground for generations of programmers. This impacts a sector employing 5.4 million, contributing 8% to India's GDP, and a crucial pillar of its middle class. Major IT firms are drastically reducing hiring and even laying off workers, contrasting sharply with an annual workforce increase of 8-9 million. While AI boosts productivity, profit margins remain stagnant due to price pressures and a shift towards higher-cost onshore consulting. India faces a challenge: pivot towards labor-intensive sectors and adapt education to AI-related skills, or risk massive youth unemployment.

Yosemite: A Century of Privatization Battles

Since 1864, when Yosemite Valley was granted to California, the conflict between privatization and public interest has been ongoing. Early private businesses operating in the valley led to legal disputes. In 1973, MCA's acquisition of Yosemite concessions sparked concerns about over-commercialization. A 2016 concession transfer saw Delaware North demanding exorbitant compensation for historical names, reigniting the debate. Now, the Trump administration's budget cuts and staff reductions are raising privatization fears, bringing Yosemite's century-long struggle back into the spotlight.

Windows 11 Gets Resizable Taskbar Icons!

Microsoft is testing resizable taskbar icons in the latest Windows 11 Insider Preview Beta. Users can now choose to always show smaller icons, never show smaller icons, or show smaller icons when the taskbar is full. When full, icons shrink to fit, preventing overflow into a secondary menu. This mimics macOS's dock behavior. The Start menu also received an update with a larger layout, offering the option to hide recently used app suggestions and display all apps on one page. Note: users might temporarily lose the new battery charge status icons introduced in January, but Microsoft plans to reinstate them soon.

Chrome Root Program Enhances Web PKI Security with Mandatory MPIC and Linting

Google's Chrome team announced that its Root Program is mandating two key security improvements: Multi-Perspective Issuance Corroboration (MPIC) and certificate linting. MPIC mitigates the risk of fraudulently issued certificates due to BGP attacks by verifying domain control from multiple geographic locations, while linting automates the detection of certificate errors, improving security. Both are mandatory for publicly trusted certificates from March 15, 2025, strengthening the web PKI ecosystem's security and stability, and reducing certificate mis-issuance. The Chrome team also plans to sunset weak domain validation methods and actively explore solutions for a post-quantum cryptography world.

The Enshittification of the Internet: Policy Failure or Technical Glitch?

2025-05-28

Science fiction author Cory Doctorow's PyCon US 2025 keynote explored the 'enshittification' of internet platforms. He attributes this phenomenon to a three-stage strategy employed by tech companies to maximize profits: locking in users, degrading user experience to benefit business customers, and finally, extracting all value from the platform. Using Google as an example, he showed how 'twiddling' algorithms manipulate search results and ad placement, harming user interests. Doctorow argues that 'enshittification' isn't a technical issue, but stems from relaxed antitrust regulation and neglected privacy legislation. He calls for stronger antitrust measures, improved interoperability, enhanced privacy protections, and other steps to reverse this trend and build a 'new good internet'.
