Meta's Superintelligence Lab Considers Ditching Open-Source AI

Meta's newly formed superintelligence lab is debating a potential overhaul of its AI strategy, possibly abandoning its powerful open-source model, Behemoth. According to the New York Times, internal discussions suggest a shift towards a closed-source model, a significant departure from Meta's traditional open-source approach. Behemoth, a 'frontier' model, was completed but delayed release due to performance issues and testing has since halted. Any decision requires CEO Mark Zuckerberg's approval.

Windows 11's Adaptive Energy Saver: Smart Power Saving Based on Load, Not Just Battery

Microsoft is testing a new adaptive energy saver mode in Windows 11 that intelligently manages power consumption based on system load, not just remaining battery. Unlike the traditional energy saver, which dims the screen, this new mode maintains brightness while optimizing background processes, pausing non-critical updates, and more. It's designed for battery-powered devices like laptops and will automatically turn on and off as needed. Currently in testing for Canary Channel Insiders, it's expected to roll out later this year.

Saudi Arabia's Futuristic 'The Line' City Faces Major Setbacks

Saudi Arabia's ambitious plan to build a futuristic 170km-long city, 'The Line,' a key part of the Neom megaproject, is facing significant challenges. The Public Investment Fund (PIF) has commissioned consultants to review the project's feasibility, following reports of substantial downsizing. The initial goal of 1.5 million residents by 2030 has reportedly been slashed to under 300,000, with only a small portion of the city expected to be completed by then. This reflects broader difficulties faced by Saudi Arabia's Vision 2030 projects due to high costs and falling oil prices, casting doubt on the future of 'The Line'.

A Nasty Postgres Bug in Logical Replication Slot Creation, and How We Fixed It

The ClickPipes team encountered a perplexing bug while creating logical replication slots in PostgreSQL: a query that should have taken seconds was taking hours and couldn't be terminated. Investigation revealed a Postgres bug where, on read replicas, creating a logical replication slot would get stuck in a long sleep loop while waiting for primary transactions to finish, making it impossible to interrupt. The team submitted a patch to the Postgres community adding an interrupt check, effectively resolving the issue. This case highlights how even mature database systems can harbor unexpected edge cases, and the vital role of open-source community collaboration in resolving them.

LLMs Fail Gracefully: Long Context Performance Degrades Even in Simple Tasks

This research challenges the common assumption that large language models (LLMs) perform uniformly well on long-context tasks. By extending the Needle in a Haystack benchmark and introducing variables like semantic matching and distractors, researchers found that even under simplified conditions, model performance degrades as input length increases. This was confirmed across conversational question answering and a repeated word replication task, revealing limitations in LLM long-context capabilities and suggesting potential challenges in real-world applications.

Android 15: 16KB Memory Pages – A Performance Upgrade

Android is transitioning to 16KB memory page sizes from the traditional 4KB, boosting performance on ARM CPUs. Starting November 1st, 2025, new apps and updates with native C/C++ code targeting Android 15+ must support 16KB pages. This change promises faster app launches (up to 30% for some), improved battery life, quicker camera starts, and speedier system boot times. Android Studio offers tools like APK Analyzer and alignment checks to help developers identify and fix compatibility issues. Developers need to recompile native code and avoid hardcoding 4KB page size assumptions. Emulator and certain devices support 16KB testing.

The Colorful History of X11 Color Names: A Clash of Standards

2025-07-15

X11 color names, originating from a simple text file `rgb.txt` mapping strings to RGB values, have a long and winding history. This list, traditionally shipped with X11, became the basis for web colors when early browsers like Mosaic and Netscape adopted it. However, inconsistencies between X11 and W3C specifications, notably with "Gray," led to quirks like the lighter "Dark Gray" in CSS. Recent X11 releases now support W3C definitions, using prefixes to disambiguate conflicting names. The `rgb.txt` file also contains numerous grayscale shades and color variations, largely ignored by W3C standards. This story highlights the complexities of standardization and compatibility in technology.

Record-Breaking Black Hole Merger Detected via Gravitational Waves

Record-Breaking Black Hole Merger Detected via Gravitational Waves

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed, resulting in a final black hole approximately 225 times the mass of our Sun. The signal, GW231123, detected on November 23, 2023, challenges existing models of black hole formation, as such massive black holes are not predicted by standard stellar evolution. The extreme mass suggests a possible formation through prior mergers of smaller black holes, pushing the boundaries of gravitational-wave astronomy and our understanding of the universe.

Fighting Tech's Inevitabilism: We Still Have Choices

This article analyzes how tech leaders use 'inevitabilism'—the assertion that an AI-dominated future is unavoidable—to shape public discourse. Drawing a parallel to a debate with a skilled opponent, the author shows how this strategy frames the conversation to pre-ordained conclusions, silencing dissent. The article critiques statements from figures like Zuckerberg, Ng, and Rometty, arguing that the future of AI isn't predetermined; we should actively shape it, not passively accept a supposed 'inevitable' outcome.

SF and Oakland Police Caught Illegally Sharing ALPR Data with Feds

Records obtained by The Standard reveal that San Francisco and Oakland police departments appear to have repeatedly violated state law by sharing data from automated license plate readers (ALPRs) with federal agencies. Despite a 2015 state law prohibiting this, logs show data sharing with seven federal agencies, including the FBI, since installing hundreds of Flock Safety ALPRs last year. At least one instance involved an ICE investigation. This has drawn sharp criticism from privacy advocates and officials, who highlight the violation of individual privacy. Investigations are underway, with promises of accountability.

The Programmer's Prison: Escaping the Trap of Bloated Software Tools

2025-07-14

This article explores the dilemma of bloated software tools: to avoid user churn, tools constantly expand their functionality, ultimately becoming cumbersome. The author proposes several solutions: limiting tool growth (impractical), decreasing switching costs (through backward compatibility and standardization), leveraging FFI (Foreign Function Interface) and IPC (Inter-Process Communication). Unix shells, using IPC, allow tool composition, but data flow is unidirectional and lacks structure. PowerShell and NuShell introduce structured data, but interoperability and version stability remain issues. RPC (Remote Procedure Call) offers a structured interface but requires extensive code modification. The author concludes that programs themselves are prisons, restricting data flow and interoperability, and teases a follow-up post exploring escape strategies.
