A programmer created a neural network-based "neural world" of a forest trail, generated in-browser from real video recordings. The process involved training a neural network on captured video and motion data, with multiple iterative improvements to increase realism. Unlike traditional game worlds, which are artist-crafted paintings, neural worlds are like photographs, directly recording real environments. The goal is to develop easily captureable, high-fidelity virtual worlds comparable to photographs, enabling new creative and simulation possibilities.
GS-Calc is a powerful, modern spreadsheet designed for big data, supporting multi-million row and column datasets, with fast performance, extensive functions, Python integration, scripting, and flexible file formats. It outperforms traditional spreadsheets in speed, handling complex data models, pivot tables, filtering, and charting with millions of data points, all while enabling in-place editing, data integrity checks, and custom function development. It is portable, offline, and suitable for high-volume data processing and analysis.
A tutorial on building a WiFi-controllable 3x5 LED matrix using a Raspberry Pi Pico and WS2812B RGB LEDs. It covers schematic design, component chaining, PCB layout, and remote control via web interface with REST API.
The article explores tales of the Yucca Man and other cryptids in Southern California's deserts and mountains, including reports of hairy humanoids, winged creatures, and shadow beasts with glowing eyes. It traces sightings from military bases, national parks, and historical legends, often linked to Native American stories, local folklore, and alleged encounters by settlers, soldiers, and hikers. The stories include mysterious footprints, strange lights, and sightings of supernatural entities, blending folklore, cryptozoology, and historical accounts spanning from the 19th century to recent times.
Synadia, creator of NATS.io, affirms its commitment to open source and the future of NATS, clarifying plans to keep the core server open source under Apache 2.0 license. The company considers licensing adjustments, including a potential Business Source License (BSL) for advanced features, to ensure sustainability. Synadia emphasizes its independence from CNCF, plans to pursue new governance models, and remains optimistic about NATS' future, focusing on technology innovation and community support.

The article discusses the decline of high art and literature, attributing it to digital culture, commercial publishing interests, and changing literary themes. It reviews Edwin Frank's book on twentieth-century novels, highlighting shifts in subject matter, notable authors, and the loss of depth in modern works. The author laments the diminishing influence of classic novelists and the fading future of the novel as a form that deeply engages human nature.
Using differential coverage compares passing and failing test profiles to identify code involved in failures. It highlights unique code paths executed only in failing tests, aiding targeted debugging by pinpointing suspicious code sections. This quick, inexpensive technique improves debugging efficiency, especially in large codebases, though it isn't foolproof.
FBI arrested Milwaukee judge Hannah Dugan for helping a man evade immigration authorities after she led officers away from a courtroom while he was being sought. She faces charges of concealing an individual and obstructing a proceeding. Her actions escalated tensions between federal and local authorities amid ongoing immigration enforcement conflicts. Dugan was briefly released after court appearance. The case highlights broader disputes over immigration policies and judicial independence.
Mary MacLane, a Canadian-born writer from Montana, gained fame in 1902 with her candid, scandalous autobiographical writings at age 19. Her confessional style revealed her inner life, sexuality, and desires, challenging social norms. Her debut, The Story of Mary MacLane, received mixed reviews but sold nearly 100,000 copies quickly, making her a national sensation. She published several books, worked as a journalist, and became a controversial public figure. MacLane's provocative self-fashioning and exploration of sexuality influenced modern discussions of self-presentation and feminist artistic resistance. She died in 1929, largely forgotten until recent renewed interest and a biography in 2025.
This project formalizes the first volume of Bertrand Russell's *Principia Mathematica* using Lean4, replicating Russell’s notation and proofs with minimal alterations. The aim is to closely follow the original proofs, while providing LaTeX annotations and metaprogramming tools to enhance understanding. The formalization is part of an exploratory effort, inspired by prior work in Coq, and serves as a learning tool to understand mathematical foundations from Russell’s perspective.
Mario Arias presented a project to build a Ruby-based interpreter and transpiler for a fictional Monkey language, aiming for a production-ready VM and JIT. The approach involved lexical analysis, parsing, AST evaluation, and transpilation to Ruby code for faster execution. Benchmarks show significant speed improvements with transpiled code. The goal is to create a fast, scalable interpreter in Ruby, combining interpretation and compilation techniques.
Scientists observed Amazon River dolphins engaging in aerial urination, where males eject urine into the air, often attracting other males. This behavior may serve as a form of communication about social status or physical condition. Urine plays a vital role in animal communication, providing information on species, gender, dominance, reproductive status, and immune systems across various animals like primates, fish, and crustaceans. Recognizing the importance of olfactory cues, recent studies suggest smell and urine-based signals are more significant in animal communication than previously understood.
The article explains that the US national debt of $36 trillion is difficult to grasp and is scaled down for comprehension. It highlights that recent government cuts (DOGE cuts) to small grants have negligible fiscal impact but significant social costs. More effective solutions include taxing foreign income of U.S. corporations and imposing a carbon tax, which could collectively save hundreds of billions over ten years, surpassing the impact of symbolic spending cuts. The article emphasizes the importance of meaningful policy actions over symbolic cuts to address the national debt.
