A 16th-century Mughal painting depicts Plato playing an instrument surrounded by seemingly sleeping animals. This unusual scene originates from Nizami's Khamsa, specifically Alexander the Great's section. Alexander holds a contest of wisdom among philosophers. Aristotle initially dominates, but Plato's unique instrument, capable of mimicking the sounds of all creatures, lulls animals to sleep and then awakens them, demonstrating a deeper wisdom. The story reflects medieval Islamic perspectives on Plato and Aristotle, showcasing Plato as a mystic.

The accidental inclusion of The Atlantic's editor in a Signal group chat used by Trump administration officials to plan a Yemen bombing, dubbed 'SignalGate', has led to a massive surge in downloads for the encrypted messaging app. The incident, which exposed secret plans and raised concerns about security protocols, caused Signal's US downloads to double their usual rate, marking the app's largest ever US growth spurt. This surpasses even the growth seen in 2021 when WhatsApp's privacy policy changes spurred a mass exodus to Signal. Sensor Tower data confirms a 105 percent increase in US downloads compared to the previous week, and a 150 percent increase compared to the average week in 2024.

A new report exposes Amazon's regional shipping restrictions for certain products on its US storefront. Researchers found 17,050 products restricted from shipping to at least one region globally. Books were the most commonly restricted product category, often related to LGBTQ+, occult, erotica, Christianity, and health topics. Affected regions included many Middle Eastern and some African countries. Amazon uses misleading error messages to hide its censorship, violating its public commitments to human rights. The report recommends Amazon improve its censorship system and increase transparency.

This article delves into the unique perspective technique employed by 18th-century artist Giovanni Battista Piranesi. Unlike traditional perspective, Piranesi's trick uses a near-large, far-small ratio when depicting a series of similar objects, rather than true perspective convergence. This technique, while violating perspective rules, enhances image readability and comprehension. The article analyzes the mathematical principles of this technique and, through comparison with traditional perspective, demonstrates its potential applications in image processing and mapmaking. The author even developed an algorithm to apply this technique to image editing software, offering a fresh perspective on image manipulation.

This article exposes the American Medical Association's (AMA) lucrative monopoly on Current Procedural Terminology (CPT) codes, used for medical billing. The AMA charges hefty royalties to software companies using these codes, a cost ultimately passed on to doctors and patients. This practice burdens physicians and influences healthcare politics, shifting AMA focus from its members' interests to its own profit maximization. The author calls for government intervention, such as invalidating CPT code copyrights or developing alternatives, to restore fair competition and the public good. The AMA's silence on Robert Kennedy Jr.'s nomination as Secretary of HHS hints at this power dynamic.

A recent study reveals a surprising gap between people's stated preferences and their actual consumption behavior regarding AI-generated content. Participants, while expressing a preference for human-created short stories, invested the same amount of time and money reading both AI-generated and human-written stories. Even knowing a story was AI-generated didn't reduce reading time or willingness to pay. This raises concerns about the future of creative industry jobs and the effectiveness of AI labels in curbing the flood of AI-generated work.

A search engine's crawler consistently struggled to finish its task, spending days on the final domains. Recent migration to slop crawl data reduced memory usage by 80%, increasing crawling tasks. This resulted in 99.9% completion in 4 days, but the remaining 0.1% took a week. The issue stems from website size following a Pareto distribution, with large websites (especially academic ones with numerous subdomains and documents) and crawler limits on concurrent tasks per domain. Initial random ordering caused large sites to start late. Sorting by subdomain count led to a surge of requests to blog hosts. Adding request delay jitter and adjusting the sort order to prioritize sites with more than 8 subdomains partially solved the problem. However, inherent limitations of the batch crawling model require further optimization.

Ian Beer of Google Project Zero details the analysis of NSO Group's BLASTPASS iMessage exploit. This zero-click attack chain leveraged a maliciously crafted WebP image disguised as a PassKit attachment to bypass the iMessage sandbox. Exploiting a Huffman coding vulnerability in the lossless WebP format, the attackers triggered memory corruption. A sophisticated 5.5MB bplist heap groom within a MakerNote EXIF tag facilitated memory overwriting during TIFF image rendering. This triggered a forged CFReadStream's destructor, executing malicious code. The attack cleverly exploited vulnerabilities in ImageIO and Wallet, bypassing BlastDoor sandbox and Pointer Authentication Codes (PAC). HomeKit traffic may have been used for ASLR disclosure. The analysis reveals the complex techniques used, highlighting the need for robust sandbox mechanisms and a reduced remote attack surface.

Rivulet is a novel programming language that uses semigraphic characters representing 'strands' to write code. Programs consist of tightly packed code blocks called glyphs, each containing several types of strands that execute together. Rivulet avoids traditional control flow mechanisms, instead using a rollback mechanism to implement conditional branching and loops. Data is organized as lists, and commands operate on single cells or entire lists. While its syntax may seem complex at first glance, it's actually quite easy to learn.

This article explores the importance of managing synchronous calls when building distributed service systems. The author introduces the concept of a "synchrony budget," advocating for minimizing synchronous requests between services to improve performance and availability. Synchronous calls are costly, impacting response times and system stability. Using an e-commerce order processing example, the article demonstrates how to handle interactions with inventory and shipping services asynchronously (e.g., using Kafka), reserving synchronous calls for situations where they're essential (like payment services). The author also covers the Outbox pattern and CDC technology for handling message buffering and data synchronization in asynchronous communication, ultimately achieving a high-performance and highly available distributed system.

The Alan Turing Institute (ATI), intended to be the UK's leading AI institution, is in crisis due to mismanagement, strategic blunders, and conflicts of interest among its university partners. The article details the ATI's origins and how it became a university-dominated, profit-driven consultancy rather than a true innovation hub. The ATI neglected cutting-edge research like deep learning, focusing excessively on ethics and responsibility, ultimately missing the generative AI boom. This reflects common issues in UK tech policy: unclear goals, over-reliance on universities, and a reluctance to abandon failing projects. The defense and security arm, however, stands as a successful exception due to its industry and intelligence agency ties.

A groundbreaking trial in Japan has shown promising results in treating paralysis using induced pluripotent stem cell (iPSC)-derived neural stem cells. One of four participants, a paralyzed man, can now stand independently after receiving injections. Another participant regained some arm and leg movement, while two others showed no significant improvement. While the results, which haven't undergone peer review, suggest the treatment is safe, larger trials are needed to confirm its efficacy and rule out natural recovery.

Anthropic's latest language model, Claude 3.7 Sonnet, demonstrates impressive planning capabilities while playing Pokémon. Unlike previous AI models that wandered aimlessly or got stuck in loops, Sonnet plans ahead, remembers its objectives, and adapts when initial strategies fail. While Sonnet still struggles in complex scenarios (like getting stuck on Mt. Moon), requiring improvements in understanding game screenshots and expanding the context window, this marks significant progress in AI's strategic planning and long-term reasoning abilities. Researchers believe Sonnet's occasional displays of self-awareness and strategy adaptation suggest enormous potential for solving real-world problems.
