High-stakes meetings in poorly ventilated rooms can impair decision-making due to high CO2 levels. A CO2 monitor can help identify and fix this issue, which is often overlooked and can be as simple as opening a window.
Astrophysicist Charlotte Mason and colleagues are studying "little red dots" discovered by the James Webb Space Telescope, which may be black holes or a new type of object. Researchers are exploring various theories to explain the dots' existence and the universe's early mysteries.
Learning new things is fun and makes life richer, but it requires a daily time investment of up to an hour. It's a long journey with initial struggles, but consistent practice leads to improvements over time.
The book is a narrative by geologist Ekaterina Radkevich about her expeditions and research on Earth and its resources. It completes the Science for Everyone Series, a collection of scientific knowledge for the general public.
AMD's Instinct MI350 series offers cheaper GPUs with comparable specs to NVIDIA's Blackwells, but lacks day-0 support for frontier models. With optimization and tweaks, AMD can achieve competitive performance per dollar, closing the gap with NVIDIA, but still requires more support and development.
Leanstral 1.5 is a free, open-source model that delivers a performance upgrade for formal verification, achieving a new state-of-the-art on FATE-H/X and PutnamBench. It verifies complex code properties and uncovers previously unknown bugs in open-source repositories.
The author, a co-founder of Databricks, discusses how traditional OLTP databases are clunky, difficult to scale, and fragile, and proposes a new architecture called Lakebase that externalizes storage and compute, making databases more durable, elastic, and cheaper to run. Lakebase's design also enables a new feature called LTAP, which unifies transactional and analytical workloads by storing ...
A Vespa museum in Rome showcases the scooter's 80-year history, from its birth in 1946 to its current status as a symbol of freedom and style. The Vespa's unlikely story began as a solution to post-war Italy's transportation needs, designed by Corradino D'Ascanio and launched by Enrico Piaggio.
New research reveals that the world's tallest tropical trees can pump water to their topmost branches without difficulty. The study found that these trees' water systems are perfectly adapted to their height, making them no more vulnerable to drought than shorter trees.
Steam Controller Auto-Charge is an open-source app that automatically charges a Steam Controller using computer vision and WebHID telemetry. It uses optical flow tracking, haptic navigation, and battery status polling to guide the controller to its charging puck.
The user discovered a severe vulnerability in MSI Center, a pre-installed software on MSI laptops and desktops, allowing for Remote Code Execution (RCE) with valid login credentials. MSI patched the vulnerability within two days and the user is still waiting for a CVE from VulDB after submitting their report.
The Spanish galleon Galeón Andalucía sailed along Ireland's west coast, visiting Streedagh Beach in Co Sligo where three Armada ships sank in 1588. The ship's visit is part of the Remembering the Armada Festival, boosting tourism and commemorating the disaster.
The user investigated why memory usage reported by fastfetch and btop differed on FreeBSD, discovering that the discrepancy was due to btop's incorrect handling of the ARC cache and filesystem metadata buffer cache. The user contributed patches to btop and htop to improve their memory usage reporting, and also submitted a PR to fastfetch, which was later merged with improvements.
SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled. - searxng/searxng
The user discusses their experience with AI and testing, highlighting the benefits of using AI to generate tests and the limitations of relying solely on LLMs for testing. They propose a testing methodology that combines fuzzing, randomized testing, and human review to achieve high-quality results, and discuss the importance of feedback loops and independent perspectives in reducing false positives.
User has $2k to spend on local machine intelligence and $40k for top-of-the-line. They have 4x RTX Pro 6000s and built a DDR4 system to host them.
Amsterdam's fire-fighting system improved in the 17th century with the introduction of new engines and a culture of inventiveness. The city's fire damage decreased dramatically after implementing the Van der Heyden brothers' suction and pressure hoses.
Calculus has two main branches: differential calculus, which calculates the slope of a function, and integral calculus, which calculates the area under a curve. The two are connected by the Fundamental Theorem of Calculus, which states that integrals are anti-derivatives, but integral calculus is generally harder than differential calculus due to its global nature.
The user discusses the importance of threat modeling in cybersecurity, explaining that it's a formal process that helps identify potential threats and vulnerabilities in a system, and provides a framework for understanding assumptions and accepted risks. They also apply threat modeling to real-world examples, including hybrid post-quantum cryptography and end-to-end encrypted messaging apps, ...
The Scanline Sweeper is a GPU-based Bézier curve rasterization algorithm that estimates coverage analytically without computing explicit winding numbers or tessellation, resulting in a numerically robust algorithm. It operates on glyph curves directly on the GPU, integrating signed areas swept by each curve intersecting the scanline of interest to produce an anti-aliased result for a single ...
GingerBill, the creator of the Odin programming language, expressed concerns about Wikipedia's deletion of the Odin article due to lack of reliable sources, but his tone shifted from dismissive to concerned after Casey Muratori, a famous videogame programmer, pointed out the flaws in Wikipedia's notability rules for programming languages. Casey argued that Wikipedia's rules prioritize ...
Anthropic and OpenAI announced efforts to use frontier models for cybersecurity, but this led to a significant increase in high-severity vulnerabilities. The number of high- and critical-severity CVEs jumped 3.5x in June after the announcements.
cardiag is a proof-of-concept audio-ML pipeline for car fault diagnosis from phone recordings. It provides a calibrated triage aid with honest uncertainty, isolating mechanical sounds and ranking likely parts.
Reflexes is a fast and cheap API for semantic signals from agent traces, built on a custom inference engine and small LLM models. It allows tracking of user frustration rates and other signals over time, scaling to tens of thousands of agent runs and millions of turns.
The Pew Research Center study found that 38% of webpages from 2013 are no longer accessible, but the Wayback Machine has rescued roughly 15% of those dead pages. Web archives like the Wayback Machine play an increasingly important role in rescuing the dead Web and minimizing the fracture of the knowledge graph on the Web.
Amazon's complex logistics model may not be the most efficient or socially beneficial, while Costco's simpler model offers lower costs and better worker treatment. A public grocery store model, inspired by Costco and the military commissary system, could provide cheaper groceries for New Yorkers with lower overhead.
This is a course based on Fong and Spivak's book Seven Sketches in Compositionality: An Invitation to Applied Category Theory, taught by John Baez and turned into nice webpages by Simon Burton. © 2018 John Baez
You spoke to a year group about manufacturing, sharing your experience making an AI clock and showing them various stages of design and production. You aim to normalize hands-on learning and inspire kids to become makers and inventors.
SQLite fixed a long-standing bug in WAL checkpointing that could lead to database corruption. The dqlite team used TLA+ to model SQLite's behavior and found that dqlite is not affected by the bug due to its stricter locking mechanism.
Researchers at the University of Kansas used network science to study lip reading mistakes, creating a visual map of 20,000 English words to improve training for lip readers and AI. The study found lip-reading errors occur when visually similar words occupy the same region in the visual network, affecting accuracy.
