The webinar titled "Let's make a programming language. Part 1. Intro" discusses the complexities of data alignment in memory, a crucial but often overlooked factor that can affect program performance. It highlights that while programs may be well-written and tested, they may still underperform due to issues related to how data is stored and accessed in memory. The session emphasizes that each variable takes up a specific space in memory, with a focus on the role of the CPU cache and the difference between processor and RAM speeds

The author reflects on their early adoption of the GNOME extension PaperWM, which allows for a unique scrolling window management style, contrasting it with the popular tiling window trend. They emphasize PaperWM's fluid navigation for users who prefer both ease and functionality. However, they note that its reliance on the GNOME environment, which is complex and prescriptive, can limit user choice. In light of this, the author has been observing niri, a new window manager designed for sliding windows, which has

The content discusses a GPU scheduling method named "Octopus," which focuses on processing variable-length batches of images without padding. The author tested three different approaches to GPU processing and shared several key findings: 1. Each CUDA block can independently manage its tasks with minimal overhead, likening it to how an octopus's arms function autonomously. 2. After benchmarking on an RTX 4090 with 10,000 images, counterintuitively, binary search proved to be faster than expected due to efficient

Mike Swanson's blog discusses the phenomenon of modern software that interrupts users for feedback and tutorials, likening it to an irritatingly intrusive car asking about your driving experience. This "backseat software" shifts from being a straightforward tool to a channel that demands user engagement. Swanson reflects on the evolution of software from physical media—like floppy disks and CDs—which users operated without constant interruption, to today's software that frequently updates and seeks user interaction. While the old model had issues such as bugs that couldn

The author expresses skepticism towards test-driven development (TDD), despite acknowledging that some aspects of it, like rapid feedback through unit tests, can be useful. The TDD process involves writing a failing test before implementing code to ensure it meets expected behavior, but the author criticizes the unwavering loyalty many have towards TDD, comparing it to a cult. They argue that while TDD promotes test coverage, it does not guarantee that the behavior being tested aligns with user or business needs. This can lead to
