Elevators use complex algorithms like SCAN and LOOK to optimize traffic flow. The best algorithm varies depending on building size and traffic patterns, with simpler algorithms sometimes outperforming more advanced ones.
Large food companies like Coca Cola, PepsiCo, and Mondelez have filed 239 lawsuits globally between 2010 and 2025 to delay or block public health laws targeting unhealthy foods. These lawsuits have cost governments billions of dollars and prolonged the public health crisis.
User upgraded their Mac Studio to 25 GbE using a cheap Thunderbolt adapter and solved thermal issues with a custom fan setup. The upgrade improved network speeds, but real-world file copy speeds were only marginally better than the built-in 10G Ethernet.
DeepSeek V4 Flash 0731 scores 50 on the Artificial Analysis Intelligence Index, placing it above average among comparable models. It costs $0.14 per 1M input tokens and $0.28 per 1M output tokens.
The user implemented a graph map-reduce using Apache DataFusion, achieving billion-scale graph analytics on a laptop with 5-10 GB of memory. They successfully computed PageRank and identified weakly connected components on large graphs, outperforming existing libraries like NetworkX and Igraph.
The DeepSeek-V4-Flash API is now in public beta with enhanced agent capabilities and benchmark results exceeding V4-Pro-Preview. It supports Responses API format and is adapted for Codex, with unchanged API calling method.

Miso Motion is building a new company supplying robotics data to AI labs, seeking a full-time hire to help build the US business from the ground up. The ideal candidate thrives in ambiguity, learns quickly, and builds long-term relationships, with experience in partnerships, business development, or operations a plus.
The user created a custom ssh-askpass tool called ssh-askpass-zigtk using Zig 0.16 and GTK4 to avoid X11 dependencies. The tool can be used by setting the SSH_ASKPASS environment variable to the path of the binary, allowing OpenSSH to prompt for SSH key passphrases in situations where a terminal is not available.
Arch Linux DevOps team has disabled adoption of orphaned packages in AUR due to malicious package adoptions and malware attacks. The team had previously suspended new account registration in June and reopened it on July 13 with minor restrictions, including email verification via a 24-hour token.
The author discusses the impact of AI on the writing industry, predicting a future where AI-generated books will coexist with human-written ones, and readers will have varying opinions on the authenticity of books. The author advises aspiring and established writers to focus on writing for the love of it, rather than seeking external validation, and believes that the personal connection ...
New models were added to the leaderboard, including GLM 5.2, DeepSeek-V4 Pro, and others. Some models were deprecated, including gpt-5-2025-08-07-medium and Claude Sonnet 4.
David Anderson introduced the "Clockwise/Spiral Rule" to parse C declarations in one's head. The rule involves moving in a spiral clockwise direction to identify array, pointer, function, and other elements in a declaration.
The author explores how people make big decisions, often relying on intuition and imperfect information, and argues that decision science can provide a more systematic approach to decision-making. However, philosophers like Edna Ullmann-Margalit and L.A. Paul suggest that some decisions, such as becoming a parent, involve a fundamental shift in values and identity, which cannot be captured by ...
Inference APIs are moving away from a simple, user-controlled model where sessions can be inspected, archived, and replayed, instead returning a mixture of text and provider-bound state that is non-portable. The authors propose a set of rules for inference providers and agent builders to adopt, including making local event logs canonical, storing data explicitly, and providing readable ...
BitBang CLI is a single static binary remote-access multitool that allows secure, peer-to-peer connections to remote machines without port forwarding or configuring. It uses WebRTC/DTLS for end-to-end encryption and supports file transfer, proxying, and interactive shell access.
Scientists use a specific type of water called Vienna Standard Mean Ocean Water (VSMOW) for precise temperature measurements due to its consistent isotope ratio. VSMOW is used to calibrate thermometers and is the most official water standard, with a limited supply and a high price of $120,000 per gallon.
Industry experts say that despite increased tools to fight phishing and robocalls, scammers adapt faster than defenses can keep up. Authentication frameworks and consumer vigilance are key, but no single solution exists to tackle the complex problem.
The Chrome Security team is using Large Language Models (LLMs) to automate vulnerability discovery and fix hundreds of security bugs faster than ever, aiming for greater resilience and comprehensive remediation. By combining AI-powered vulnerability detection with traditional security testing and mitigation strategies, Chrome is driving towards a browser that is continuously protected without ...
WASTE is an embeddable inference engine written in C that streams large models from disk, allowing them to fit on consumer machines. It achieves this by keeping the model trunk in memory and streaming selected experts directly from disk.
Hungary's only nuclear power plant will shut down due to record low Danube River water levels, threatening the country's energy supply. The shutdown, combined with a heatwave, may lead to a critical energy situation, prompting the government to limit electricity consumption.

Defcon's conference badges this year feature an innovative open source chip called the Baochip-1x designed by Andrew "bunnie" Huang, which aims to advance security, transparency, and trustworthiness in computing. The chip can be removed from the badge and used as a hardware security token, and its design allows for inspection and verification of its internal structures, making it a more ...
Researchers found a configuration of 5 point charges with at least 24 non-degenerate critical points, disproving Maxwell's conjecture. Maxwell's conjecture stated that n point charges have at most (n-1)^2 non-degenerate critical points.
