Infidel goes wild

In a detailed technical analysis, Andrew Plotkin has identified a severe memory corruption bug within the classic Infocom interactive fiction title Infidel. Utilizing a memory-level debugger, Plotkin discovered that a ZIL compiler error causes a "wild pointer" bug when players drop items in the Endless Desert region. Rather than utilizing the correct DESERT-TABLE address, the game writes data to unintended memory locations, potentially overwriting the abbreviations table and causing garbled text or interpreter crashes. This flaw managed to evade detection by both developers and players for decades, as the specific circumstances required to trigger the error were rarely encountered during typical gameplay.

The Philadelphia Inquirer built Scrape, an AI tool to surface hyperlocal news

To address the challenge of sourcing hyperlocal news from fragmented sources like municipal meetings and social media, The Philadelphia Inquirer developed Scrape, an AI-driven tool designed to automate news lead discovery for its community newsletters. Developed through the Lenfest AI Collaborative and Fellowship Program with assistance from AI Fellow Kevin Hoffman, the tool was built using an iterative, human-in-the-loop process that prioritized existing editorial workflows over purely technical experimentation. By training the AI on curated tip sheets and embedding specific editorial context—such as audience interests, geographical boundaries, and explicit exclusions like routine road closures—the team successfully transitioned Scrape from a manual 12-hour-per-week task into "load-bearing and critical infrastructure" for multiple newsletters. The project demonstrates a successful blueprint for newsrooms by encoding human judgment into AI prompts to improve the signal-to-noise ratio in local reporting.

What is going on with ceiling fans

The article examines the chaotic evolution of ceiling fan design, noting how e-commerce giants like Wayfair and Amazon have flooded the market with bizarre, "algorithmic" fixtures. Driven by the flexibility of integrated LED lighting, a new genre of hybrid products has emerged, including "fandeliers"—chandeliers with fans—and "chandefans." These mass-produced items often prioritize sculptural, non-traditional shapes over functional utility, frequently utilizing cheap plastic and non-replaceable lighting components that contribute to environmental waste. The author suggests this trend represents a breakdown of traditional architectural integration in favor of strange, disconnected hybridizations that blur the lines between light and air movement.

Treachery in the Rodin Museum 3D scan verdict

In an eight-year legal struggle, activist Cosmo Wenman and digital rights groups including Communia and Wikimédia France were ultimately denied access to 3D scans of Auguste Rodin’s sculptures held by the Rodin Museum. Although a lower court in the Administrative Tribunal of Paris initially ruled that the high-resolution 3D point cloud scans were administrative documents subject to public disclosure, the Conseil d’État, France’s highest administrative court, overturned the verdict. The high court determined that these digital assets are part of the museum's inalienable collection rather than administrative records, effectively exempting them from freedom of information (FOI) laws. This ruling establishes a precedent that allows cultural institutions to maintain exclusivity over digital reproductions of public domain works, which Wenman argues undermines the principles of open culture and digital accessibility.

Page Table Memory Consumption

The article examines the significant impact of page table memory consumption on modern system performance and stability. While multi-level page tables offer superior TLB efficiency compared to hashed tables, they pose a substantial memory risk when numerous processes map identical shared memory regions. The author details historical and contemporary instances where massive page table growth—driven by shared memory in databases like Oracle, Postgres, and ClickHouse—has triggered Out-Of-Memory (OOM) failures. While the use of Huge Pages can mitigate this overhead, it introduces challenges regarding memory fragmentation and allocation. Furthermore, the text highlights emerging complexities in NUMA architectures, where researchers must balance the latency of remote page table walks against the memory costs of replicating tables across multiple nodes, as explored in the Mitosis and Hydra studies.

A Minsky machine in ncurses terminfo

Nicolas Seriot demonstrates that ncurses terminfo parameter expansion can simulate a two-counter Minsky machine, effectively rendering the system computationally universal. While terminfo lacks native loops, its capacity for arithmetic, logic, and persistent variables allows it to function as a small programming language when an external process provides a "clock" via repeated expansion. The author illustrates this capability through addition and Fibonacci programs, including a "parasitic" Fibonacci machine that executes within a terminal while being clocked by the periodic screen redraws of /usr/bin/top. Although this demonstrates how user-controlled terminfo is interpreted by potentially privileged host processes, the article concludes that the behavior is a functional quirk rather than a security vulnerability.

Safe Optimistic Lock Coupling

As CPU core counts continue to rise, traditional lock coupling in concurrent data structures often suffers from performance bottlenecks caused by physical contention on synchronization locks. To solve this, Thomas Neumann highlights Optimistic Lock Coupling, a technique that provides near-lockfree read scalability by using version numbers instead of standard locks for readers. To prevent the potential for race conditions when developers fail to validate these version numbers, the approach integrates validation requirements directly into the C++ type system. By utilizing specialized wrappers like unvalidated types and OptimisticPtr, the compiler can enforce that data is only accessed after successful validation, ensuring high-performance concurrency without sacrificing correctness.

Decision models like Jev don't beat LLM-as-a-judge or traditional classifiers

A study by Red Hat researchers examined the efficacy of emerging decision models, such as TypeSafe’s Jev, in comparison to traditional AI guardrail methodologies. By testing various candidates across prompt injection and content safety benchmarks, the researchers compared pre-trained text classifiers, zero-shot classifiers, and LLM-as-a-judge architectures against Jev-style models. The findings revealed that while decision models provide advantages like type safety and low cost, pre-trained predictive models remain highly competitive due to their superior speed and accuracy for well-defined risks. Although LLM-as-a-judge remains a viable but resource-heavy option, the study suggests a shift toward pragmatism in model selection to effectively balance accuracy, latency, and computational costs.

'Neanderthals Among Us' review

In Neanderthals Among Us: The Making of a Prehistoric Human, Peter Sahlins examines the evolution of the Neanderthal from its 1856 discovery in Germany to its multifaceted role in modern science and popular culture. As reviewed by Helen Wickstead, Sahlins traces the trajectory of the Neanderthal image, moving from 19th-century racial science and "brutish" cinematic caricatures to contemporary genetic realities. By bridging the gap between archaeological findings and a vast corpus of media—including novels, films, and political discourse—Sahlins illustrates how the "Neanderthal" has served as a shifting cultural symbol. Ultimately, the book highlights how ancient DNA has proven that Neanderthals are integrated into the modern human genome, while cautioning against biological determinism by framing our view of these ancestors as a Rorschach test for human identity.

A 40ms Go garbage collector pause caused by swap

Fernando Simões warns that using swap to manage memory spikes in production can trigger severe Go garbage collector (GC) pauses. His research demonstrates that while the Go runtime reads internal metadata during stop-the-world (STW) phases, the kernel may evict these non-heap pages to swap. This results in major page faults that can spike GC pauses from a median of 51 $\mu$s to as much as 40ms—an 800-fold increase that halts all Ps in the runtime and can delay critical I/O operations. Additionally, testing indicates that the Go 1.26 Green Tea garbage collector provides negligible mitigation for this issue.

So you think you could be an electrician?

In the essay "So You Think You Could Be An Electrician?", Jesse Smith challenges the popular narrative that the skilled trades serve as a guaranteed, AI-proof alternative to the rising costs of college. Smith argues that the perceived economic benefits are often overstated, noting that college graduates still generally command higher lifetime earnings and that the trades carry significant risks of permanent injury or death. He further dismantles the idea that trades are an easy fallback, pointing to the intense competition for high-status union roles and the complex internal hierarchies within blue-collar labor. Critically, Smith suggests that Artificial Intelligence may not spare the trades, as mechanization and AI-driven coaching could reduce the demand for both human dexterity and specialized cognitive expertise. Rather than a "magic ticket" to prosperity, Smith presents the trades as a nuanced career path that requires careful consideration of physical, social, and technological realities.

TurboPython – A Python-to-C++ Compiler

TurboPython, also known as TPy, is a general-purpose, statically typed language that compiles Python code through C++ into standalone native binaries. Distinguishing itself from standard CPython, the language utilizes an ownership and borrowing model to provide memory safety and predictable performance without a garbage collector, automatic reference counting, or a Global Interpreter Lock (GIL). While it retains familiar syntax, TurboPython enforces strict type annotations and lacks dynamic features like monkey-patching or direct compatibility with external pip packages; instead, all dependencies must be written in TurboPython or ported to its subset of the standard library. Currently in early development, the toolchain is distributed via PyPI as tpy-lang and requires C++23-compliant compilers such as GCC 13+ or Clang 19+.

Fixed Points and Strike Mandates (2012)

In his analysis, Paul Khuong examines the mathematical nuances of fixed point computations, noting a common tendency to design algorithms that converge to suboptimal results by failing to distinguish between the least and greatest fixed points of monotone functions. Drawing on Tarski’s fixed point theorem, Khuong illustrates this through examples like dead value elimination in compiler optimization and applies the concept to student union strike mandates in Québec. He suggests that to avoid deadlocks in strike mobilization, organizers should avoid "bottom-up" algorithms that seek the least fixed point and instead adopt a "top-down" approach—assuming all mandate-holding unions are striking and iteratively removing those that fail to meet specific thresholds—to identify the greatest fixed point.

We're going to need default hard budget caps on pretty much everything

In a recent article, Simon Willison argues that pay-by-usage services and APIs must implement default hard budget caps to protect users from massive, unexpected bills caused by runaway processes or AI agents. Unlike "soft caps" that only send warning emails, hard caps would automatically terminate services and return errors once a financial threshold is met. Willison contends that these safeguards should be the default setting, requiring an explicit opt-in for those who wish to operate without limits. He notes that AWS has recently begun rolling out spending limits and Google Cloud introduced Spend Caps in July, signaling an industry trend toward providing more robust financial protections for builders.

Agents don't need memory, they need documentation

In his analysis of AI agent architectures, Kevin Liao argues that the current industry focus on memory plugins using Retrieval-Augmented Generation (RAG) is fundamentally flawed. He contends that these systems rely on similarity-based retrieval from vector databases, which often results in the loss of critical context and provides unreliable, unauditable "memories." Instead, Liao advocates for documentation-based memory, where agents maintain a structured Markdown workspace to record specs, research, and instructions. By shifting the agentic loop from mere recall to a cycle of consult, build, and update, agents can develop a more cohesive understanding of their projects. To implement this vision, Liao offers Operator Memory, an open-source tool that replaces black-box embeddings with a transparent, document-driven Markdown brain.

City building games have a Soul Problem pt.2

In a second installment of his critique of the genre, Alex Lingris argues that modern city-building games, specifically Cities: Skylines 2, suffer from a lack of "soul" due to an obsession with sterile, geometric perfection. Lingris contends that the "neurotic cleanliness" and unrealistic, square surfaces of these simulations fail to capture the organic, lived-in character of real urban environments. To improve immersion, he suggests that developers should integrate gritty, visual details such as potholes, graffiti, scaffolding, and decaying infrastructure. By neglecting these imperfections and the visible socioeconomic nuances of actual cities, current titles miss the opportunity to use the landscape as a storytelling tool, ultimately resulting in a lifeless experience that lacks the complexity of real-world life.

Your body of work thinks back at you

In the essay "Your Body Of Work Thinks Back At You," photographer cedric explores how long-term photographic archives can reveal unintended social patterns and truths. By reviewing years of seemingly incidental images of public seating, the author discovered an inadvertent documentation of hostile architecture—the practice of designing street furniture to be uncomfortable or impractical in order to exclude certain populations from public spaces. The piece argues that while photographers often strive for deliberate intent, the true power of a body of work lies in its ability to act as an involuntary witness, allowing meaningful social critiques to emerge through the retrospective analysis of accumulated evidence that the photographer never consciously sought to capture.

Woking Electrical Control Room (2016)

The Woking Electrical Control Room, a Grade II listed building constructed in 1936, served as one of five facilities designed to manage electricity for the Southern Rail network. Designed by architect James Robb Scott and built by the Swedish firm Asean, the structure features a non-descript concrete exterior that hides an ornate, oval-shaped interior with a white domed ceiling. The control room is distinguished by its decorative cast iron poles supporting large copper dishes with bulbous lights, as well as black control panels used to manage substations and prevent railway downtime. Although the facility ceased its primary operations in 1997, the building's offices remain in use, and the site occasionally opens to the public during the Open London heritage weekend.

How to hack time, with C2PA

Researcher David Buchanan, known as retr0id, has revealed a vulnerability in the C2PA metadata standard that enables a technique termed "time-hacking." By exploiting the protocol's "exclusions" feature—which permits certain byte ranges to be omitted from signature calculations—an attacker can exclude an entire file to sign an empty string. This allows for the attachment of a valid, timestamped signature to an image that can then be modified, such as by forging lottery numbers, without invalidating the Time Stamp Authority (TSA) proof. Because existing verification tools currently fail to flag these large exclusions, the flaw presents a significant challenge for ensuring the authenticity of digital content.

Former SR-71 engineer talks NASA's Blackbird revival program

Former NASA propulsion engineer Tim Conners has shared insights regarding the potential revival of the SR-71 Blackbird, specifically Tail 844, as a specialized high-speed engine test bed. Following speculation triggered by NASA Administrator Jared Isaacman's comments on a new high-speed X-plane, Conners suggests the agency may be aiming to use the legendary aircraft to validate new high-Mach engine technologies rather than for aerodynamic research. Despite significant obstacles—including the potential unserviceability of the original J58 engines, the disappearance of the specialized JP-7 fuel, and nearly three decades of component degradation—current reports indicate that NASA may soon begin "power-on testing" at the Armstrong Flight Research Center to assess the aircraft's electrical systems.

What's the future for pure math research in the age of AI?

In his analysis, Stephen Wolfram argues that Artificial Intelligence will not replace pure mathematics but will instead function as a powerful tool to augment human inquiry. Wolfram distinguishes between the raw, rule-based generation of theorems via computational irreducibility—which often produces "alien" mathematics—and the essential human role of defining goals, asking meaningful questions, and constructing conceptual narratives. While Large Language Models are highly effective at mining the existing corpus of human knowledge and identifying patterns, the aesthetic and creative aspects of mathematics remain uniquely human. To bridge the gap between automated computation and human understanding, Wolfram suggests utilizing high-level computational systems like the Wolfram Language to create a nexus where human intuition, AI, and formal computation can work in tandem to advance the field.

Second Chances

In his essay Second Chances, Jonathan Lethem explores the modern wave of literary rediscovery, centered on the reissue of Wilfrid Sheed’s 1966 novel, Office Politics. While examining the role of specialty presses like McNally Editions in reviving out-of-print works, Lethem provides a nuanced critique of Sheed’s legacy. He praises the author’s urbane, ironic wit and the precise, comedic depiction of power struggles within a small magazine, but ultimately argues that Sheed's tendency toward skepticism and "cranky conformity" often precludes a deeper emotional engagement with his subjects.
