VisiCalc Reconstructed (54 points by ingve)
VisiCalc Reconstructed: This article details a personal project to rebuild a minimal clone of VisiCalc, the pioneering 1979 spreadsheet software. The author explains the core data model, formula evaluator, and simple UI needed, highlighting how VisiCalc's efficient design allowed it to run on limited 16K RAM machines. The piece serves as both a historical appreciation of a foundational "killer app" and a technical guide to understanding spreadsheet internals.
ArXiv declares independence from Cornell (605 points by bookstore-romeo)
ArXiv declares independence from Cornell: This article reports on the arXiv preprint server's move to become an independent entity separate from Cornell University, which has hosted it since its inception. This shift aims to ensure the long-term sustainability and governance of the critical open-access repository for scientific papers, particularly in physics, computer science, and related fields.
Delve – Fake Compliance as a Service (58 points by freddykruger)
Delve – Fake Compliance as a Service: This investigative article accuses "Delve," a compliance platform, of systematically fabricating audit evidence and misleading clients about their adherence to regulations like HIPAA and GDPR. It claims the company uses offshore "certification mills" and violates auditor independence rules, leaving customers exposed to significant legal and financial risk despite believing they are compliant.
The Los Angeles Aqueduct Is Wild (117 points by michaefe)
The Los Angeles Aqueduct Is Wild: This educational article (a video transcript) explores the history and engineering of the Los Angeles Aqueduct, which transports water over 300 miles from the Sierra Nevada. It describes the aqueduct's pivotal role in enabling LA's growth, the dramatic moment of its 1913 opening, and its ongoing status as a vital yet controversial piece of infrastructure that reshaped California's water politics.
Entso-E final report on Iberian 2025 blackout (125 points by Rygian)
Entso-E final report on Iberian 2025 blackout: This presents the final report from the European network of transmission system operators (Entso-E) on a major blackout in Spain and Portugal in April 2025. The report concludes the cause was a complex combination of voltage oscillations, reactive power control gaps, and uneven generator stabilization, leading to cascading failures. It issues recommendations for improved grid monitoring, coordination, and adapted regulatory frameworks to prevent future incidents.
Parallel Perl – autoparallelizing interpreter with JIT (14 points by bmn__)
Parallel Perl – autoparallelizing interpreter with JIT: This presentation abstract discusses a project to integrate AI into the Perl programming language, specifically through an autoparallelizing interpreter with a Just-In-Time (JIT) compiler. The author, who has worked on AI with Perl for decades, frames this as "letting AI do Perl," suggesting the use of machine learning techniques to optimize and potentially transform code execution.
The Social Smolnet (48 points by aebtebeten)
The Social Smolnet: This blog post proposes leveraging existing decentralized tools—blogs and email—as a social network, avoiding the need for new protocols. It introduces new "share" and "reply" commands in the Offpunk gemini/gopher browser that automate sharing links and contacting authors via email, arguing that this simple approach can recreate core social networking functions with established, user-controlled technology.
France's aircraft carrier located in real time by Le Monde through fitness app (50 points by MrDresden)
France's aircraft carrier located in real time by Le Monde through fitness app: Based on the title and context, this article reveals a security breach where the real-time location of a French aircraft carrier was compromised due to data from a fitness tracking app (like Strava). It highlights how aggregated data from consumer wearables and apps can pose significant national security and operational security (OPSEC) risks by inadvertently revealing sensitive movements.
Video Encoding and Decoding with Vulkan Compute Shaders in FFmpeg (92 points by y1n0)
Video Encoding and Decoding with Vulkan Compute Shaders in FFmpeg: This technical blog explains the integration of Vulkan compute shaders for video processing within FFmpeg, a major multimedia framework. It addresses the need for high-performance, flexible software encoding/decoding for professional workflows (like 8K film scans) where dedicated hardware may be insufficient or unavailable, marking a shift towards open, cross-platform GPU acceleration.
HP realizes that mandatory 15-minute support call wait times isn't good support (193 points by felineflock)
HP realizes that mandatory 15-minute support call wait times isn't good support: This article reports on HP's now-abandoned policy of intentionally imposing a mandatory 15-minute wait message on support calls in several European countries, regardless of actual queue length. The stated goal was to push customers toward digital self-service options, but the policy was widely criticized as a misguided and customer-hostile approach to support cost reduction.
