Node.js version 23.6.0 enables "type stripping" by default, allowing users to run TypeScript code without transpilation if it contains only erasable TypeScript syntax. Since version 22.6.0, Node.js has offered experimental support for TypeScript syntax through the `--experimental-strip-types` flag, which removes type annotations before execution. In version 22.7.0, the support was extended to include TypeScript-only syntax like enums and namespaces with the `--

The document discusses the biology of color perception, highlighting the role of cone cells in the retina that respond to different wavelengths of light. It explains that these cone cells have overlapping sensitivities, making it difficult to isolate the perception of a single color. Fong et al. (2025) conducted an experiment where they stimulated only M cone cells using lasers, resulting in subjects reporting a vivid blue-green color that had not been previously experienced. However, the paper lacks detailed subject reports, despite many authors being

Last week, GitLab addressed several critical authorization vulnerabilities, while McDonald's experienced a major data leak involving 64 million job applications due to an insecure direct object reference (IDOR). Since July 2024, ZeroPath Security Research has utilized large language models (LLMs) to analyze codebases for authorization bugs, discovering their widespread presence not because they are new but because they can now be identified programmatically. Authorization vulnerabilities have remained a persistent issue, continuing to be ranked as the top vulnerability in the

The latest insights suggest that perceptions of productivity gains from AI among software engineers may be exaggerated. A study conducted by the Model Evaluation & Threat Research (METR) organization involved 16 developers working on GitHub projects, comparing their performance on tasks designated as "AI allowed" versus "AI disallowed." Developers estimated they would complete tasks 24% faster with AI assistance, but the results showed they took 19% longer instead. The study aimed to assess whether AI truly accelerates software development, and

The author reflects on an ARTE documentary about Neapolitan pizza, particularly appreciating the animated illustrations that accompanied the recipe. These illustrations, despite being static, feature a "jitter" effect that makes them appear to move slightly. This effect, known as "boiling" or line boil, is achieved by drawing the same frame multiple times with slight variations in position and rotation, creating the illusion of movement. The technique enhances the visual experience by making static images feel more dynamic. The author also observes

The content discusses the challenges of using "magic booleans" in Java code, which can lead to confusion about their meaning when trying to maintain or read code. The author emphasizes the importance of using enums instead of boolean values for clearer code. By using enums, the intent becomes self-documenting, errors can be caught at compile time, and the code is easier to understand and maintain. The piece also introduces CodeRabbit, a tool that helps developers identify bad practices, including the use of boole
