The author solved a Jane Street challenge by reverse-engineering an ASIC using Python and constraint solvers, overcoming significant technical hurdles along the way. They successfully extracted the circuit's components and simulated its behavior to find the password hidden within its structure.
OpenAI has released GPT-6 Astra, the world's most intelligent and aligned model, offering state-of-the-art performance in computer use, browsing, software engineering, cybersecurity and more. The new model is available to all ChatGPT Plus users and will be rolled out to other plans over the coming days.
A user's .name domain is set to be destroyed due to Verisign's proposal, causing their website and email address to vanish. This could lead to potential security risks as vacant 2nd-level domains may become available for registration by others.
O&O ShutUp10 is a free tool that lets users control Windows 10 and 11's data sharing and convenience features. It provides simple, customizable settings to protect user privacy without requiring expert knowledge or installation.
A historic San Francisco building's outdated elevator system was upgraded to a modern, overhead traction variable frequency-controlled AC gearless system with improved safety and efficiency. The renovation involved replacing old machinery with new energy-efficient gearless hoist machines and re-engineering the existing offset basement design.

The company SubImage is hiring engineers to tackle complex security challenges with its infrastructure mapping tool, built on Cartography. They're seeking experienced engineers with a strong background in distributed systems and cloud tech to join their team in the SF Bay Area.
Cerebras offers free trial and pay-as-you-go models with rate limits, while dedicated endpoints provide reserved capacity and production SLAs. The company hosts original, unpruned open-source models from the community on its public endpoints.
What if electricity got cheaper when the grid runs clean and pricier when it runs dirty? Every day this site runs that idea on real electricity-grid data and measures how much CO₂ it would save compared with today's standard pricing — across Switzerland and US grid regions.
The author argues that authorization models like RBAC, ABAC, and PBAC are often misclassified due to a lack of understanding of the different axes involved in an authorization system. The six axes include authority administration, authorization model, policy expression, access control mechanism, enforcement location and architecture.
A massive data breach has exposed 153 million driver's license scans, available for sale on the dark web, highlighting the huge privacy risks of age verification technologies. This breach is a stark warning to those pushing for age verification laws and shows that no system can be completely safe from data breaches.
Researchers built artificial beaver dams in northern California to recreate lost wetlands and boost coho salmon survival. The project, published in Frontiers in Ecology and Evolution, showed significant success with juvenile coho survival rates increasing from 8% to 60%.
Julia is a high-performance programming language used by millions of users worldwide for scientific research, data analysis, and modeling complex systems. Its "just-in-time compilation" feature makes it faster and more flexible than other numerical programming languages.
Shin Jin-seo, a 26-year-old South Korean Go grandmaster, defeated the world's top AI engine KataGo in a historic three-game series under a two-stone handicap.
The author of the game Babylonian Twins, built in 1993 on an Amiga 500, has had his original code ported to modern platforms using AI assistance. The port was done by running the original assembly code through a model that could understand and execute it.
The author attended a party celebrating the 50th anniversary of Ted Nelson's hypermedia manifesto, Computer Lib/Dream Machines. The event featured vintage computers running Xanadu implementations and stories from former programmers about the challenges of developing hypertext systems in the past.
IFM is releasing K2 Horizon, a connected fleet of six models with top-tier performance across various tasks. The models are released under the Apache 2.0 license and provide an open blueprint for understanding and advancing AI systems.
A 1966 BBC documentary featured Gerald Hawkins, a Boston astronomy professor who claimed to have solved the mystery of Stonehenge using an early IBM computer and astronomical calculations. He believed that the monument was used as an astronomical observatory to predict eclipses over 4,500 years ago.
Researchers created a panel of 75 GitHub repositories to test how coding agents choose third-party services, analyzing over 16,893 runs. They found that popular players like Stripe and Azure often win due to their simplicity and cost-effectiveness, but lesser-known providers can also succeed in specific scenarios.
Scientists have discovered that a massive solar storm in November 2025 caused widespread disruptions to the US atmosphere, including coast-to-coast disturbances and significant errors in GPS positioning. The effects of this event could have been devastating for industries relying on precision navigation, such as autonomous vehicles and agriculture.
The author advises using std::move rarely, citing return value optimization (RVO) and copy elision as the preferred methods to avoid unnecessary copies and moves. With C++23, implicit move is now supported in both cases where it was previously required or not possible.
Jernej Barbič, a professor of computer science at USC, developed Ziva VFX software for realistic muscle and skin simulations in 3D digital humans and creatures. His technology has been used in over 60 movies, including Aquaman and the Lost Kingdom.
User is discussing MCP, a tool for natural language interaction with APIs and tools. They find it useful for automating tasks and reducing errors, but acknowledge its limitations.
The author revisits the concept of hypertext and its pioneer, Ted Nelson, who envisioned a system called Xanadu that could manage complexity and version control. The author believes that modern technology has finally made it possible to build upon Nelson's ideas.

The author created Jactl, a secure scripting language for Java applications that compiles to bytecode and allows long-running operations without blocking the execution thread. It uses a continuation mechanism to save the execution state of scripts when they are suspended due to long-running operations.
Western Electric, a subsidiary of AT&T, operated a massive metal recycling facility on Staten Island from 1930 to 2001, processing millions of tons of scrap and producing valuable metals for the telephone industry. The site was eventually remediated after years of environmental contamination and is now considered suitable only for limited industrial use due to strict institutional controls.
