Ivan Shubin shares his experience with using matrices in his interactive diagramming editor, Schemio. Initially, Schemio allowed users to create and manipulate simple shapes with basic properties like position, size, and rotation. However, to enhance the application's capabilities, he implemented an item hierarchy that enables users to group shapes for complex interactions, similar to features found in both diagram editors and game engines. This added functionality required translating between local and world coordinates, which proved challenging. Shubin reflects on the power

The post discusses performance issues encountered while using QEMU-based virtual machines for testing in NixOS, which utilizes the Plan 9 File Protocol (9p) to avoid generating disk images for each test. The author experienced unexpectedly long file transfer times—over 2 hours for copying approximately 5.3GiB of data—when accessing files from the 9p-mounted Nix store. Recognizing this was not practical for incremental work, they investigated and successfully reduced the transfer time to just

MIT cognitive scientists suggest that the complex language of legal documents, known as legalese, is purposefully convoluted to convey authority, similar to how magic spells use specific terms. In a recent study published in the Proceedings of the National Academy of Sciences, researchers found that even non-lawyers instinctively write in this convoluted style when creating laws. The study, led by graduate student Eric Martinez and senior author Edward Gibson, examined the structure of legal documents and identified characteristics such as "center-embedding,"

The Java team at Oracle is working on Project Valhalla, which aims to bridge the gap between classes and primitive types in Java by introducing value classes. These value classes are designed to function like classes yet behave like primitive types (e.g., integers), while also providing improved memory efficiency. This significant restructuring, referred to as Java's epic refactor, has been in progress for a decade and is now nearing completion. At Devoxx 2024, Java Language Architect Brian Goetz provided a

The content discusses the significance of physical standards and their application to both hardware and software industries. It highlights how standardized components, like the 1/4-20 bolt, enable compatibility and accessibility across various machines, leading to lower costs due to economies of scale and competition. This principle, articulated by Wright’s Law, illustrates that increasing production leads to cheaper unit costs. In the software realm, the absence of coherent standards has created a chaotic environment where reliance on vendors and proprietary solutions often leads to high costs

Rust has gained popularity as a systems programming language due to its performance and ability to eliminate memory and concurrency errors at compile time. While most programmers should avoid writing unsafe Rust, some libraries utilize it for enhanced performance, memory manipulation, or integration with other systems. This article discusses tools for verifying unsafe Rust code, particularly in the context of operational technologies and critical infrastructure. Sanitizers are tools that identify programming errors such as memory corruption or data races during run-time by injecting checks into the code at compilation.
