Robert Vanderbei has written a beautiful series of articles and talks about a method for finding the radius of the earth based on a single photograph of a sunset over a large, calm lake. Vanderbei’s analysis is an elegant and subtle exercise in classical trigonometry. In this post, I would like to present an alternative analysis in a different language: Geometric Algebra. I believe that ...
A hypernetwork estimates parameters for local neural heat fields, combining components with phase shifts and thermal activations. This results in a blurred, continuous field that's rasterized for a final output image with guaranteed anti-aliasing.
Sketch-programming (or simply "Sketch") is a revolutionary approach to writing software that prioritizes simplicity, readability, and expressiveness. Unlike traditional programming languages or frameworks, Sketch is not a specific language but a meta-programming paradigm—a set of principles, conventions, and syntax patterns designed to abstract away boilerplate code, reduce cognitive ...
We're celebrating Douglas Adams' 73rd birthday by honoring his legacy as a comedic genius who taught us to laugh at existential terror. His works continue to inspire our podcast, which merges quantum physics with office politics, reminding us to find humor in the absurdity of existence.
Researchers introduced Dynamic Tanh (DyT) as a normalization layer replacement in Transformers, achieving similar or better performance without hyperparameter tuning. DyT is effective across various tasks and architectures, challenging the conventional understanding of normalization layers in neural networks.

Briar is a secure messaging app that synchronizes messages directly between users' devices, protecting against surveillance and censorship. It uses Tor, end-to-end encryption, and decentralized design to keep information flowing even during internet blackouts.
Intuitive Machines' Athena spacecraft landed on the Moon but failed to operate due to a power shortage caused by regolith on its solar panels. Despite this, the mission was considered a success as it validated the spacecraft's propulsion system and communications technology.
The font uses a vertically striped background with reversed letterforms, inspired by Schaefer Versalien. Kerning is achieved through GSUB lookups, splitting letters into pieces and recombining them with a joiner glyph.
Deepnote aims to create collaborative tools for data teams, making data work fun and efficient. It's building a notebook that integrates analytics and data science into workflows, empowering teams to work together seamlessly.
We're bad at marketing We can admit it, marketing is not our strong suit. Our strength is writing the kind of articles that developers, administrators, and free-software supporters depend on to know what is going on in the Linux world. Please subscribe today to help us keep doing that, and so we don’t have to get good at marketing. Mozilla's actions have been rubbing many Firefox fans ...
The James Webb Space Telescope found that most galaxies rotate in the same direction, contradicting random expectations. This discovery could support the theory that the universe was born inside a rotating black hole.
Mayo Clinic uses a novel technique to address AI hallucinations by linking data points back to their original sources. This approach eliminates data-retrieval-based hallucinations in non-diagnostic use cases.
I recently helped a company recover their data from the Akira ransomware without paying the ransom. I’m sharing how I did it, along with the full source code. To clarify, multiple ransomware variants have been named Akira over the years, and several versions are currently circulating. The variant I encountered has been active from late 2023 to the present (the company was breached this year). ...
Transit agencies are misled by hydrogen bus claims due to cognitive biases and flawed analyses from credible organizations. They overlook battery-electric buses' reliability and falling costs, investing in costly hydrogen infrastructure instead.
A critical security incident has compromised the tj-actions/changed-files GitHub Action, exposing secrets in over 23,000 repositories. Users are advised to stop using the Action, review logs, and use Harden-Runner for real-time security monitoring and anomaly detection.
You'll be available for 6 hours and want to discuss recent changes and potential changes in U.S. immigration law, policy, and practice. You'll provide factual information and avoid giving legal advice on specific cases.
Yann LeCun suggests LLMs may never fix hallucinations due to token choice errors. He proposes an 'energy minimization' architecture to minimize overall response 'energy' during training.
“Before all else, let me make the acquaintance of my reader, and express my sincere esteem for him and the deep pleasure it is to me to address one so wise and so patient.” Welcome to the home of the Peirce Edition Project! Our online doors are always open. Come inside, don’t shut your eyes, but open your mouth perhaps, and on each page Peirce will give you something pithy to make you wise. ...
Mathematicians Hong Wang and Joshua Zahl proved the three-dimensional Kakeya conjecture, establishing a limit to how small a pencil can move in midair. Their proof has significant implications for the field of harmonic analysis and may lead to breakthroughs in related problems.
User recommends Milton drawing software for note-taking and problem-solving, especially with a graphics tablet like Wacom Bamboo. It helps stay motivated by visualizing thought process and planning.
US restaurant labor productivity surged 15% during the COVID pandemic and persisted post-pandemic. The surge is linked to reduced customer dwell time, particularly take-out customers spending 10 minutes or less.
This web audio toy is part of my research into sparse representations of musical audio and the decomposition of audio signals into systems of resonances and sparse control signals. Code for this experiment is here
Researchers introduced block diffusion language models that combine benefits of autoregressive and diffusion models, enabling flexible-length generation and improved efficiency. This approach sets a new state-of-the-art performance on language modeling benchmarks and allows for arbitrary-length sequence generation.
Some birds, like Northern Mockingbirds, continue to learn and add to their song repertoire as they grow older, possibly to impress potential mates or deter rivals. Mimicry can serve various purposes, including attracting mates, defending territories, or warning off predators, but learning the wrong songs can be detrimental to a bird's survival.
The temple of Khnum in Esna, Egypt, features a well-preserved entrance hall with vibrant colors and intricate reliefs depicting Egyptian gods and astronomical phenomena. A team of conservators has cleaned the hall, revealing previously hidden images and inscriptions that provide insight into ancient Egyptian theology and culture.
