A Trivy supply chain attack compromised GitHub Actions, impacting over 10,000 workflows, and was enabled by a compromised credential with write access to the repository. The attack delivered an infostealer via 75 modified version tags, targeting sensitive data in CI/CD environments.
The quadratic all-matches problem in regex engines has been a long-standing issue since the 1970s, causing worst-case time complexity of O(m * n²) when searching for multiple matches in a large input. A new regex engine called RE# has been developed to solve this problem, offering a hardened mode that guarantees linear time even on adversarial input, and a normal mode that is faster but may ...
The user designed an I/O co-processor called BIO for the Baochip-1x SoC, which is a more efficient alternative to the Raspberry Pi's PIO. The BIO uses a RISC-V 32-bit core and a set of FIFO-registers to achieve determinism and flexibility, and can be used for various I/O tasks such as DMA and SPI bit-banging.

The user discusses best practices for research, including avoiding overview slides, developing a unique view of the world, and staying on top of literature, and emphasizes the importance of collaboration, communication, and time management in research. They also provide tips for staying organized, reading efficiently, and avoiding burnout, and encourage researchers to view their work as a ...
The user built an AI receptionist named Axle for their brother's luxury mechanic shop to answer customer calls and provide accurate information about prices, hours, and policies. The system uses Retrieval-Augmented Generation (RAG) and a custom-built knowledge base to ensure accurate and grounded responses, and can also collect callbacks for unknown questions.
This repository contains experimental code for thread-like processes that blend the Posix process model with multi-threading, enabling zero-copy access to pointer-based data structures. The code has limitations, including no support for debugging, ptrace, or signals, and requires careful memory management due to independent libc instances for each threadproc.
An Air Canada plane collided with a firefighting vehicle at LaGuardia Airport, causing significant damage and prompting a ground stop. The incident occurred when the plane, with 76 people on board, landed and struck a responding vehicle.
Years of countless pours led me to the question “Is this really a pint? They say so, but really?” The findings gave rise to the Pint Patrol, a grassroots movement that could change how Americans are served their beer, wine, and cider—toward righteous honesty. This article documents the initial discovery and the inception of the movement.
User is moving services from non-EU countries to EU providers due to global politics and improved data protection. They've switched to European alternatives for email, hosting, DNS, Git repositories, and VPN services.
Walmart ended its Instant Checkout deal with OpenAI due to low conversion rates. It will now use its own chatbot, Sparky, to offer a seamless shopping experience within ChatGPT.
The PC Gamer article has a cluttered interface with multiple ads and popups, including a 37MB initial load. The website continues to download new ads, totaling almost half a gigabyte in five minutes.
Companies using Dspy report benefits like quick model testing and maintainable systems, but implementing Dspy-like patterns can be hard and lead to worse versions. Dspy forces you to think about abstractions upfront, which can be a steep learning curve, but is necessary for complex AI systems.
GitHub has experienced several outages this month, including issues with Actions, notifications, and Copilot. The company's overall uptime has been poor, dropping below 90 percent at one point in 2025.
General Motors is supporting the restoration of a rare 1996 EV1 electric vehicle, VIN 212, which was purchased at auction for over $100,000 and is being restored by a YouTube channel and private collector. The restoration is part of GM's recognition of the EV1's 30th anniversary and will help return the vehicle to driving condition and public visibility by November 2026.
The author appeared on a German gaming podcast, Stay Forever, to discuss the technology behind RollerCoaster Tycoon. The game's creator, Chris Sawyer, wrote it in Assembly, a low-level language that allowed for high performance.
The article discusses how collaboration has become a misguided obsession in the modern tech industry, leading to a lack of accountability and productivity. It argues that most complex work is done by individuals or small groups with clear authority and accountability.
The author criticizes C's assignment expressions and pre/post-increment/decrement expressions for being hard to reason about due to their side-effectful nature. They argue that these expressions make code harder to understand by burying side effects within trees of expressions.
The user argues that while AI helps with precision in coding, it also creates an illusion of precision, which can lead to bugs and complexity issues when scaled up. The user believes that good code is not just about producing working software, but also about creating beautiful, well-structured abstractions that help master complexity, and that AI will be a boon for coding, not a replacement for it.
Alison Bennett, a mom in Los Angeles, bought a Tin Can phone for her 8-year-old daughter to chat with friends without a mobile phone. The phone runs off WiFi and has parental controls, allowing kids to communicate with approved contacts during approved hours.
Manyana is a project that presents a coherent vision for the future of version control using CRDTs, which provide eventual consistency and informative conflict markers. It offers a better design for version control, including permanent line ordering, informative conflicts, and preserved history, making it a promising proof for CRDT-based version control.
The 64 hexagrams of the I Ching have two canonical orderings: the binary natural order (0–63) and the King Wen sequence (~1000 BCE). Treating the map between them as a permutation in S₆₄, its cycle decomposition yields [52, 10, 2] with zero fixed points. 81% of hexagrams are locked in a single cycle. As far as we can find, this specific cycle type has not been previously reported.
The user created a low-budget electromagnetic fault injection (EMFI) tool using a piezo-electric lighter and an antenna wire to induce memory errors in a laptop's DDR bus, then used this tool to write a local-privilege-escalation exploit for CPython. The user then used a similar EMFI tool to create a reliable exploit for Linux, allowing them to gain root access by corrupting page tables and ...
