A vulnerability in Microsoft's Copilot for Word allows attacker-controlled instructions to be copied into documents, potentially leading to confidentiality impacts through Cross-Domain Prompt Injection Attacks (XPIAs). The attack can self-propagate across trusted document workflows, making it difficult to detect and respond to, and highlighting a broader architectural weakness in current ...

On this day 18 years ago I launched the Amiga Graphics Archive with the goal of creating a curated gallery with high quality and rare pixel art images made with and for the Commodore Amiga computer. As a special treat, I've added an image by Jim Sachs called Multimedia that I found in a badly scaled version, that I was able to restore pretty close to its original state. See more updates...
SpecForge is a tool for writing and analyzing specifications in the Lilo language, which is used for hybrid systems. It provides features like syntax highlighting, type-checking, and analysis capabilities in VSCode.
The demo scene, a digital art subculture, has a long history of creating its own tools, including assemblers, trackers, and other software, often with unique and quirky user interfaces. These tools, such as Seka, AsmOne, and ProTracker, were used to create demos, music, and graphics, and often featured peculiar designs and features that were characteristic of the scene.
To achieve ultra-low latency in SQLite, configure WAL mode, manage busy handlers, and leverage custom Virtual File System (VFS) layers, and pair WAL mode with the NORMAL pragma to prevent disk synchronization bottlenecks. Properly configuring SQLite with WAL mode, memory mapping, and transaction boundaries can handle hundreds of concurrent requests and millions of queries per day on a modest ...
The chapter discusses implementing a Forth environment on Lisp, exploring the concepts of abstract registers, threaded code, and duality of syntax, and how these features make Forth a powerful and flexible language. The author also touches on the idea of brevity and how it relates to the productivity of programming languages, and how macros can provide a duality of syntax that allows for more ...
Codex Security is an open-source CLI and TypeScript SDK for finding, validating, and reviewing security issues in code. It supports macOS, Linux, and Windows, and requires Node.js 22 or later.
A Dutch engineer has created OmnesViae, a tool that allows users to plot routes between ancient Roman cities and estimate travel times on foot or horseback. The tool uses ancient sources like the Tabula Peutingeriana and the Antonine Itinerary to calculate routes and provide detailed information on intermediate stops.
HNewhere detects Hacker News stories, loads comments into a sidebar, and lets you browse discussions without leaving the page.
Writers should not make Substack their digital home, as it's short-sighted and can derail long-term visibility on the internet. Instead, they should treat their website as the definitive source of truth and use platforms like Substack as distribution pipes.
Half-Life, a story-driven first-person shooter, has been ported to PowerPC Macintosh computers 28 years after its original release. The game, developed by doctashay using Xash3D FWGS, is playable from start to finish with multiplayer support and additional downloads.
Learn by editing with real nvim, racing vimbot on keystrokes. Practice 72 skills, from basics to advanced, with a vimbot to compete against.
Kimi K3 is a scaled-up version of Kimi Linear with a new LatentMoE component and attention residuals. It improves inference efficiency and validation loss, but adds 4% training and 2% inference cost.
RADV, an open-source Vulkan driver for AMD GPUs, has been successfully ported to Windows, allowing for a shared codebase and easier debugging across platforms. The project has made significant progress, including running the game Counter-Strike 2, but still requires work on presentation and communication with the proprietary kernel driver to achieve production-readiness.
reFrame is an experimental camera with a color ePaper display that captures one photo at a time, taking 15 seconds to fully appear. It's open source, allowing users to build their own using off-the-shelf components like a Raspberry Pi Zero and eInk display.

SBCL has released new versions with various bug fixes, optimizations, and minor incompatible changes. The updates include improvements to the compiler, documentation, and platform support, as well as fixes for issues related to type checking, memory management, and foreign function calls.
LearnVector aims to revolutionize learning with AI, providing one-to-one experiences that adapt to each person's needs. It plans to collaborate with Coursera and Udemy to offer trustworthy learning experiences.
Learning to program requires a long-term commitment of 10 years or 10,000 hours of deliberate practice, not just a few days or hours of book learning. To become a skilled programmer, focus on hands-on experience, working with others, and continually improving your skills over time, rather than relying solely on books or training courses.
Researchers propose a unified model called Transformer Transformer that generates a complete robot for a specific task by optimizing its design for a given motion and reward function. The model uses a diffusion transformer trained on RoboTokens, a unified tokenization of robot embodiments, states, and actions, to produce optimized robot designs for various tasks and reward functions.

PostgreSQL's MVCC design is criticized for causing write amplification, bloated tables, and delayed cleanup, but its critics often fail to consider the trade-offs and costs of alternative designs. Other databases, such as Oracle, MySQL, and MongoDB, have their own versions of MVCC that address some of the same issues but introduce new problems, highlighting the complexity and trade-offs ...

The University of California, Berkeley released version 4.2 of its UNIX operating system in 1983, which included the BSD 'sockets' model of networking and led to a massive increase in access to network services worldwide. The sockets system provided a simple, consistent way to connect to ARPANET systems, making it easy for programs to communicate over networks and revolutionizing online services.
The US Navy's nuclear-powered submarine USS Triton circumnavigated the globe underwater in 1960, proving submarines could operate completely submerged. This marked a significant shift from older subs that spent most of their time on the surface.
The Zig compiler's incremental compilation feature allows for fast rebuilds by detecting changed code and recompiling only that, patching the resulting bytes into the output binary. The feature involves caching source files' generated ZIR, tracking dependencies between analysis units, and using a linked file abstraction to handle incremental linking.
