The author works on the live services game "Dragon Prince: Xadia," which has iOS and Android clients, game servers, and a platform. To keep clients and servers synchronized, a dynamic version value is included in the platform's YAML configuration, allowing clients to know when updates are necessary. Recently, the QA lead reported that the Sandbox2 shard was incorrectly prompting users to update, despite having the latest client and server deployed. The author suspected a deployment issue or incorrect git hash. After verifying

The delete operator in JavaScript is an older feature that aims to remove property references from objects rather than deleting values like numbers directly. Using `delete 0` does not lead to actual deletion in the execution system. Typically, when a property is successfully deleted, the operator returns true; if it fails, it returns false. Notably, the delete operator affects only an object's own properties and will skip any properties found in the prototype chain. If a property is non-existent, the delete operation has no

Synthetic diamonds have become purer, more beautiful, and significantly cheaper than mined diamonds due to advancements in manufacturing technology developed over decades. A diamond, composed of a strong carbon atom lattice, is the hardest natural material and has unique properties such as high thermal conductivity and electrical resistivity. While natural diamonds take billions of years to form and often contain impurities, lab-grown diamonds can be produced more quickly and cost-effectively, allowing for new applications. Initially, synthetic diamonds were small and impure, suitable only

The author previously misunderstood the terms concurrency and parallelism, often used interchangeably. After reading Chapter 9 of "Clojure for the Brave and True," they realized that these concepts are distinct, prompting a desire to learn more, particularly in the context of JavaScript. The author explains three methods of task execution: sequential, concurrent, and parallel. Sequential execution involves completing tasks one after another without overlap, which can lead to inefficiencies if one task is blocked by waiting for another (e.g

In recent years, there has been a noticeable resurgence in the development of command line interface (CLI) tools, particularly after a period of limited activity between 1995 and 2015. This trend involves not just the creation of new tools but also the rethinking and redesign of traditional command line staples. The terminal and CLI have been important features of computing since the late 1950s, with many foundational Linux commands originating from the first Unix version in 1971. While these tools, such

The author is observing the xenocog community and projects emerging from cyborgism concepts. They are particularly fascinated by how individuals like Janus, ampdot, and Theia Vogel interact with language models (LLMs) in innovative ways, treating these models with intellectual respect. Instead of focusing on how to build a Discord bot, the author is intrigued by the mechanics of interaction within group chats and how LLMs can participate naturally. They discuss the typical limitations of chat models and express interest in identifying

The article discusses AT Protocol, the technology developed by Bluesky for open social networking, through the lens of distributed backend engineering. It begins by contrasting traditional web architecture, which relies on a single SQL database and can become a performance bottleneck, particularly for large-scale social networks. As performance issues arise, solutions such as caching and sharding are introduced, but these still struggle with strong consistency requirements. To improve scalability, the article advocates for moving to a NoSQL system that employs eventual consistency. However,
