Discord handles millions of users on its servers by optimizing its system using technologies like BEAM (Erlang Virtual Machine) and Elixir. BEAM's lightweight processes and message-passing capabilities enable high concurrency, while Elixir simplifies Erlang's syntax. Discord optimized its fanout system for updates by using Elixir processes to help manage servers and user clients.
Tailwind CSS is popular due to its low bundle size, high performance, built-in code splitting, and improved readability due to classes being embedded in markup. This article particularly focuses on the color management system in Tailwind CSS and the need for dynamic themes, allowing users to choose interface colors. It explains the challenges of implementing dynamic themes, especially regarding color perception, and introduces the OKLCH color space as a solution. It also outlines steps for integrating dynamic colors with Tailwind CSS, creating semantic classes, and managing user color choices through methods like local storage.
DoorDash streamlined microservices caching by developing a Kotlin library that standardizes caching across multiple microservices. The library enhances performance and resolves caching issues like cache staleness and heavy dependency on Redis. This standardized caching allows teams to focus more on their own business logic and less on the overall performance of the caching.
We tend to think about our careers as being straightforward, following a laid-out path of milestones and achievements. But in reality, a person’s career can take a nonlinear route which might include changing titles or even industries. This article lays out a new way to look at a nonlinear career that can empower people with this background.
Refactoring code in a development team can be explained in economic terms to non-technical managers. To encourage management to allow developers time to refactor a codebase, the article suggests providing answers to questions such as how much longer future projects will take without refactoring, the potential cost savings from refactoring, and what features may become impossible without it. The article also recommends presenting multiple options for refactoring, including "Monster refactoring," "Refactor as you go," and "Slice and dice."

Reactime is a Chrome developer tool available as open-source, designed for time travel debugging and performance monitoring in React applications. With Reactime, developers can capture snapshots of their application's state, navigate between and examine these snapshots, and track performance metrics, including component render time and frequency.
This article delves into the technical challenges and issues faced by the game "Cities: Skylines 2." The game's heavy GPU usage is due to the excessive rendering of unnecessary geometry, which is caused by a lack of simplified LOD variants for many of the game's meshes and an apparently untuned culling implementation. The developers likely initially adopted Unity's new technologies like DOTS but had to implement custom solutions for various aspects of the game due to limitations in Unity's integration and technical challenges.
This article discusses the use of React for building game UIs using Unity. It presents two approaches to using React in Unity: embedding a browser or WebView and a browser-less approach that interprets JavaScript into native game engine UI code. It also outlines a workflow for coordinating interactions between the browser and Unity using state machines.
