The author argues that when starting a new web application, the initial delivery should be a blank page rather than a minimum viable product or prototype. The rationale is that shipping nothing allows developers to avoid lengthy debates over architecture and to minimize risks. By deploying a blank page, teams can gradually build features, test riskiest aspects, and incorporate user feedback without the complexities of a fully developed product. This approach helps in making critical decisions and simplifies the evolution of the software. Ultimately, starting with nothing allows for

The author attended the NAB (National Association of Broadcasters) show with their father to explore topics related to broadcast timing and live production. Initially expecting to learn about technologies like grandmaster clocks and various AV sync protocols, the author instead discovered a unique booth featuring an expensive oscilloscope. The scope was monitoring a GPS PPS timing signal and a broadcast TV signal from KSNV-TV, revealing a pulse sync of +/- 10 ns between GPS and an experimental timing standard known as BPS, which may

Bram.us is a technical weblog founded in 2001 by Bramus Van Damme, a web developer from Belgium. Recently, a tweet by Haroen Viaene highlighted an issue in YAML known as "The Norway Problem," where the abbreviation for Norway (NO) is incorrectly parsed as false. To avoid this, values like NO should be enclosed in double quotes or processed with libraries like StrictYAML that do not convert them incorrectly. Other YAML issues discussed include the handling of version numbers that end

The article discusses the messaging patterns provided by the zero-copy communication library iceoryx2, which are suitable for various inter-process communication scenarios. Current patterns include publish-subscribe for distributing sensor data, request-response for command execution with feedback, and event messaging for triggering actions based on specific events. However, these patterns can sometimes be insufficient for certain use cases. To address this, a new messaging pattern called "blackboard" has been designed and will be implemented in Q2 2025. This pattern

The author initially focused on automating the process of taking screenshots for weekly progress updates, developing code to capture images in both light and dark themes at various pixel densities to avoid blurriness on high-DPI screens. They aimed for consistency in image resolutions, opting for a size of 360x240 pixels while ensuring different pixel densities, despite the limitations of this small resolution. Additionally, they experimented with rendering rounded rectangles but found little guidance on pixel transparency. After a break, they discovered a method involving

The content discusses implementing SVG within a JSX (or React) context, emphasizing its use for creating animated and stylized elements. It explores techniques for creating a Table Of Contents (TOC) that is server-rendered to maintain compatibility with Server-Side Rendering (SSR). Since server-rendered elements don't have exact positions, the approach involves using absolute positioning and different components that are stitched together. The main feature is an interactive animated thumb that highlights TOC items as they become visible in the viewport.

The article discusses the importance of performance considerations when using embedded scripting languages in game engines, particularly focusing on Lua 5.4.7. It highlights that, although Just-In-Time (JIT) interpreters exist, scripted code typically underperforms compared to native code, such as compiled C99. This performance gap is attributed not only to the inherent differences between P-code and machine code but also to how data structures and memory usage impact CPU performance. The author emphasizes that complex algorithms should generally
