The author expresses a passion for concise and elegant tests in software development, emphasizing the importance of clarity and efficiency. They lament the common practice of mocking framework dependencies, deeming it not only unsightly but also detrimental in the long run. This approach leads to brittle tests, increased maintenance challenges, and integration issues. Citing the principle "Don't mock what you don't own" from the London School of Test-Driven Development, the author warns against mocking external code, as it can create outdated expectations and

A Message Queue is an asynchronous communication method used in distributed systems to facilitate message exchange between services while decoupling the sender and receiver. This enables reliable task execution (like email sending or data processing) even if some services are slow or down. Message queues are beneficial for managing high loads, enhancing reliability, and improving system scalability and resilience. They offer three delivery guarantees: at-most-once, at-least-once, and exactly-once, and can prioritize messages to ensure critical ones are processed

In the article by Exequiel Rozas, the author discusses challenges that arise when an application depends on screen size, particularly when users resize their browser windows. While CSS media queries and container queries handle some of these issues, they may not be sufficient. To address this, the Resize Observer API is introduced as a modern JavaScript solution that allows developers to observe and respond to changes in the size of specific elements, rather than the entire window, making it more efficient. The Resize Observer API is preferable

As applications grow, so do their database tables, which can lead to increased memory usage when fetching all columns, including large text or JSON fields. This post discusses strategies to optimize memory usage in Rails applications by querying only the necessary data from the database. Initially, it may be practical to use methods like Model.all or Model.where to retrieve full records. However, as new columns are added—such as a bio column containing large amounts of text—memory usage can quickly escalate. For example, adding bios

A "Dark Mirror" ideology is a belief system that stands in moral opposition to a "Light Mirror" ideology but maintains the same factual claims about the world. The primary difference between these ideologies lies in their proposed actions or solutions to issues. Such ideologies are considered rare in real life but often arise in online political debates, where opponents assume that their adversaries secretly agree with them but choose to act on evil intentions. An example is the debate over minimum wage, where opposing camps may not be

Rsync is a command line tool used for transferring and synchronizing files on Unix-based systems, including macOS. While macOS has long included rsync, it only provided version 2.6.9, released in 2006, due to licensing issues. Rsync 2.x is licensed under the GPLv2, which Apple could comply with, but the newer rsync 3.x is under GPLv3, which Apple found non-compliant. As a result, macOS
