David Thompson's blog post "My favourite Git commit," written six years ago, highlighted a detailed and whimsical commit message from a co-worker that many, including the author, found enjoyable and memorable. While revisiting the post, the author realized they couldn't justify why it was an effective example of good software engineering, despite its charm. The commit message in question described a complex debugging process for a seemingly simple whitespace error, including six paragraphs and five code snippets. This meticulous account contrasted with how most developers would

The author expresses frustration with discussions about microservices in architecture review meetings, noting they often lead to unproductive debates due to the lack of a formal definition. The ambiguity surrounding the term causes confusion, resembling the "blind men and the elephant" scenario where everyone describes different aspects but fails to align on a common understanding. As a solution, the author suggests banning the term "microservices" in favor of focusing on practical challenges like feature deployment, system coupling, and scalability. The overarching point is that micro

The article discusses the process of hardening Go services by enabling Position Independent Executables (PIE). PIE allows executables to be loaded at any address in memory, which complicates attacks that target specific functions, such as exploiting buffer overflows to execute specific code like `system()`. While PIE has been a standard practice in operating systems for many years with minimal downsides, it is not enabled by default in Go, creating a need to opt-in. The author emphasizes the importance of enabling PIE,

In 2012, GitHub experienced a security breach due to a Mass Assignment vulnerability, where a user exploited the system to gain administrator access to the Ruby on Rails project. This vulnerability arises when an application unintentionally assigns multiple values to object properties from user input. For instance, if user data is submitted without proper filtering, unauthorized properties (like 'admin' access) could be unintentionally updated, creating significant security risks. To combat this issue, Rails developers have adopted the strong parameters API,

Shaffan Mustafa reflects on his career in software development in his blog, noting a growing belief that the field may be overly saturated with software. Initially drawn to development to understand technology better and contribute to open-source projects, he transitioned into a professional role. However, he became aware of the increasing complexity and tooling in corporate environments, often prioritizing company interests over user needs. For instance, he questions the frequent demand for heavy frameworks like React in job descriptions, suggesting that simpler solutions could suffice for many

The Dragon spacecraft, on its journey to the International Space Station (ISS), performs a series of maneuvers to position itself closer to the station. After executing final docking maneuvers, the vestibule is pressurized, and the hatch opens for crew ingress. The Falcon 9 rocket first lifts Dragon into orbit, where the stages separate, and Dragon activates its systems. It then executes orbit-raising maneuvers to align with the ISS, establishes communication, and autonomously approaches and docks with

The story discusses concurrent data structures in Ruby, emphasizing the potential for true parallelism using global mutable state—something not currently supported by Ruby's built-in features. While familiarity with Ruby, Rust, and C is beneficial, it is not required. Code examples are available in a GitHub repository, and users should have a relatively recent version of Ruby (preferably the master branch) along with Rust and C compilers to run the examples.

The content discusses the performance optimization of the jq tool used for processing large GeoJSON files, specifically a 500MB file containing the Alameda County Assessor's parcel map. The author finds that a current query running on this file takes about 5 seconds, which they see as suboptimal. Upon compiling the jq source code without flags from its original Launchpad source, a slight improvement (2-4%) in speed is achieved compared to the Ubuntu binary. To further enhance performance, the author rebuilds

The author, a Software Developer based in Melbourne, Australia, discusses a common reluctance observed in coding environments to create new types within codebases, specifically drawing from experiences in Java and Go projects. They note that developers often rely on numerous local variables or large numbers of function arguments instead of defining new types, possibly due to a fear of disrupting existing structures or designs. The author reflects on their early hesitation to introduce new classes, feeling it might complicate the project for others. However, they argue that

Flying model rockets offers students a safe and cost-effective way to learn about forces in motion, specifically weight, thrust, lift, and drag. Among different types of model rockets, the whoosh rocket is a variation developed by Roger Storm and Mark Skor, using a two-liter soda bottle as its frame. Unlike standard water rockets, which use pressurized water for propulsion, whoosh rockets utilize a lighter combustible alcohol-air mixture. This results in a lower thrust generation and a flight pattern resembling ballistic, usually
