The article discusses the implementation of a durable, distributed, and highly available log system using Amazon S3, as part of a series on this topic. It emphasizes the importance of logs in data and event streaming systems, noting that they are immutable, ordered collections of records with unique sequential identifiers. The author highlights the advantages of using S3 for log storage due to its zero disk architecture and the append-only nature of logs. For implementation, each record is stored as an object in S3 with a unique

The content discusses the development of a new feature for a website that showcases page previews with an image and text when hovering over links. Initially conceived four years ago, the project was inspired by a previous volunteer's idea. The challenge involved handling millions of pages stored as raw wikitext without burdening editors to manually assign thumbnails. A software engineer, Max Semenik, created an algorithm to automatically select appropriate images for articles, but it required adjustments to meet the specific needs of page previews. The team

The author describes a creative approach to motivating themselves to run by using an IoT dog food dispenser filled with M&Ms as a reward system tied to their running distance monitored via the Strava API. This system proved to be highly effective, leading the author to regularly run long distances and even complete a half marathon, eventually moving on from the dispenser's rewards. Reflecting on adulthood, the author expresses a newfound understanding that adulthood involves juggling a myriad of maintenance tasks rather than simply knowing the date. This

The content discusses the detrimental effects of an overemphasis on measurable outcomes in both healthcare and education. It begins with a morning scene in a hospital where a patient’s needs are overlooked amidst routine medical measurements, drawing a parallel to a classroom where a teacher focuses solely on standardized test scores, neglecting the individual students. This highlights a broader issue: systems are prioritizing metrics over the human experience. While acknowledging the value of measurements in both fields—advancements in medical technology and educational assessments—the article

A loop buffer is utilized in a CPU's frontend to store a limited number of previously fetched instructions, allowing for the execution of small loops while conserving power and enhancing performance by bypassing certain frontend limitations. This technique has been employed by major chip makers like Intel, Arm, and AMD. Notably, AMD's Zen 4 is the only high-performance core from AMD that incorporates a loop buffer, which is referenced as a micro-op dispatch source in its documentation, with a capacity of 144 entries,

The article discusses the common misunderstandings engineers face regarding concurrency in program design and system architecture. These misunderstandings often arise from differing internal assumptions about how concurrent processes function, which can remain unnoticed until they become costly to fix later in development. To mitigate this, the author suggests using concurrency diagrams, which visually represent the system's components and their interactions over time. These diagrams help clarify assumptions and can even alter the creator's perspective on system sequencing. Time is plotted along the vertical axis, while functional components are
