The content discusses event-driven architecture using the metaphor of making a "blog soup," which involves combining various elements to create a nutritious system. It emphasizes the importance of events, which record occurrences and support business observability, especially in Event Sourcing. Events can be processed either synchronously or asynchronously, with inline projections providing consistency but potentially slowing down event appends and increasing the risk of deadlocks. The author suggests that simple projections work better with inline processing, while more complex workflows benefit from asynchronous methods.

Part III of the series on low-level memory management in C, C++, and Rust focuses on the representation of abstract types as concrete bit patterns and how polymorphism is implemented. The article highlights key points from Parts I and II, where memory organization and ownership principles were examined. In Part I, it was established that every data type has a specific size and alignment, and the necessity of padding to meet alignment constraints was discussed. A comparison was made between well-ordered and poorly ordered structs in C

When designing a software system, you must choose an architectural pattern, with three main types dominating modern development: 1. **Monolith**: This approach consolidates the entire application, including UI, business logic, and data access, into a single deployable unit. It's suitable for early-stage products and small teams, allowing for rapid validation of ideas without the complexity of managing multiple services. However, challenges arise with scaling, riskier deployments, and potential system-wide failures due to bugs. 2.

The content is an enthusiastic introduction to the concepts of Functors, Applicatives, and Monads, often considered challenging in computer science, particularly within functional programming. The author compares these terms to the dreaded NullPointerException and notes their daunting reputation, especially among junior developers. However, they argue that these concepts aren't as intimidating as they seem, likening them to everyday patterns for handling "wrapped" values or containers, like Maybe in Elm. The author encourages readers to see familiar programming patterns, such as

Gossip Glomers are a series of distributed system challenges developed by Fly.io and Kyle Kingsbury, utilizing the Maelstrom platform and Jepsen verification framework to test various services. The aim is to create a node that communicates with other nodes and services via stdin/stdout to implement specific workloads, while Maelstrom manages scheduling and fault injections to evaluate the node's behavior under adverse conditions. The author chose to tackle these challenges in Rust, despite the availability of a Go library for Maelstrom

In a year-end reflection posted on January 4, 2026, the author reviews significant trends and events in the database industry over the past year. They note a mix of exciting developments and predictable trends. Noteworthy mentions include the rise of "vibe coding," the Wu-Tang Clan's time capsule project, and Databricks securing two large funding rounds instead of going public. On the more predictable side, Redis Ltd. reverted their licensing and SurrealDB achieved impressive benchmark numbers despite data

The author discusses their interest in mruby, specifically its ability to create standalone executables, which often face compatibility issues when run on different systems than they were built on. They mention that while mruby has some cross-compilation capabilities, it can be complex and challenging, particularly when trying to build for MacOS from Linux. However, they discovered Cosmopolitan Libc, a project that allows C to be built and run anywhere, similar to Java but without needing an interpreter. Cosmopolitan Libc

Josh Winn reflects on his experience with mobile web access following Hurricane Helene, which severely impacted Western North Carolina. After the storm, many cell towers were damaged, resulting in limited access to critical information. On the day after the storm, he struggled to load emergency websites and gather information on road closures, often encountering slow-loading pages and technical errors. He recalls driving to a location with better service and facing difficulties navigating government websites due to poor design, excessive media, and broken links. He emphasizes the need
