Researchers created a benchmark of 65 tasks to test language-model agents following long policy documents. The benchmark, which simulates real-world work environments, found most agents failed to consistently follow policies due to issues like overriding rules and losing details over time.
The user compared the performance of DuckDB and SQLite as embedded databases in the Traceway binary, finding that DuckDB writes 4x to 15x faster and serves dashboards at 100x the row count. The DuckDB build outperforms the SQLite build in all scenarios, making it the recommended choice for self-hosting the full OTel stack on a small server.

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 ...
Claire, a game developer with experience on console and VR, shared her experiences with using Godot engine for VR development, including the challenges of rebuilding the core and the community PS5/PSVR2 port. She also discussed the need for a more standardized API for platform plugins and the importance of community involvement in engine development, highlighting her own efforts to create a ...
A jailbroken Kindle can run Tailscale with improved features like SSH, proxy mode, and TUN mode, allowing it to connect to other devices on the network. A Tailscale plugin for KOReader also enables proxy interfaces for reaching content servers from the Kindle or other e-paper devices.
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...
Hunter-gatherers in Norway transported brown trout into isolated mountain lakes at least 7000 years ago for summer foraging. They likely used wooden fish traps and may have transported fish in waterskins to provide a predictable food supply.
GitHub has implemented several security improvements to prevent supply chain attacks, including account protection, safer workflow defaults, and credential revocation. These changes aim to disrupt and limit the impact of attacks, making GitHub's products more secure by default for open source communities and enterprises.
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.
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.
A texture-based technique evaluates Bézier curves on the GPU using fixed-function linear texture interpolation hardware for improved performance. This method extends to B-splines, NURBS, and other advanced curve types with potential efficiency gains.
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.
Echologue turns voice notes and journal entries into structured memory, making it askable and retrievable. It captures moments, moods, and thoughts, then indexes them for later recall.
ALP is a state-of-the-art lossless compression algorithm for IEEE 754 floating-point data, exploiting decimal and high-precision patterns. It outperforms other schemes in decoding speed, compression ratio, and compression speed.
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.
I'm unable to summarize the input as it appears to be a random collection of characters. Can you please provide a clear and concise input that I can summarize for you?
EFF opposes surveillance pricing, a practice where corporations charge different prices based on personal data. Banning this practice would be good for consumers, as it would prevent companies from exploiting people's personal information to charge more.
Valve is sponsoring Collabora engineers to port the open-source RADV Vulkan driver to Microsoft Windows. They are working on integrating RADV with AMD's official Windows kernel driver, requiring reverse engineering and a stable interface.
