The author's experience highlights the tension between configuring computer environments and maintaining productivity. Many programmers either avoid setting up their tools or become overly focused on constant reconfiguration. The author has used Alacritty as their terminal for years but is curious about alternatives like WezTerm and Kitty, questioning whether switching terminals could provide meaningful benefits given the significant time spent in a terminal daily. They decided to explore Ghostty, a highly praised terminal, which ultimately replaced Alacritty in their setup but didn't greatly revolutionize

The article discusses the common adage, "Good, fast, cheap — pick two," which suggests that compromises in engineering are inevitable. It argues against the notion that cutting corners leads to cost-effective software in the long run. While shortcuts may yield immediate savings, they can lead to performance issues and decreased quality over time, resulting in a problematic codebase often referred to as the "Big Ball of Mud." The author emphasizes that achieving good, fast, and cheap software is possible if certain principles are

The key to writing readable code lies in maintaining the right level of abstraction. Srinath Perera reflects on a talk by Venkat Subramaniam, emphasizing that, similar to how one might summarize a weekend with high-level statements rather than exhaustive details, code should present high-level algorithms while omitting unnecessary specifics. This involves structuring procedures such that the main entry points provide a clear overview, with sub-procedures diving into further detail without overwhelming the reader. Achieving this balance allows future programmers

The author reflects on their experiences with Twitter, noting its potential for inducing rage but acknowledging its value for staying updated on graphics research and game development. They discuss a recurring debate on whether to use IDEs and debuggers versus basic text editors for coding, highlighting the polarized opinions on both sides. Some argue that needing a debugger signifies a lack of understanding, while others assert that lacking debugging skills indicates incompetence. The author advocates for a balanced perspective, emphasizing the necessity of using whatever tools are most effective

Unifies Logging is a framework designed to standardize the logging process across JavaScript libraries. It offers a user-friendly API for easily incorporating tags, metadata, and errors into logs. Initially, users can employ console logging and later transition to other logging providers without modifying their application code. The framework also supports plugins for transforming, enriching, and filtering logs, allowing customization of the logging pipeline. Additionally, it enables simultaneous log distribution to multiple logging libraries and cloud services like DataDog and New Relic.

The article discusses the author's experience with pool allocators, a memory allocation method that provides simplicity and high performance compared to traditional malloc. Pool allocators allow for the allocation and freeing of memory blocks, known as chunks, in constant time. They require a fixed pool size, making them faster but less flexible than malloc. The implementation is based on the author's ANSI C library, libpool, and improvements such as resizing pools may be addressed in the future. The piece also covers the definition of a Chunk type

Tavian Barnes discusses an anomaly in latency related to the SHLX instruction on Alder Lake performance cores. With input from Twitter and Hacker News, he gains insights into the anomaly's occurrence, tied to register renaming — a CPU optimization that maps architectural registers to a larger set of physical registers using concepts like Tomasulo's algorithm. This renaming can eliminate certain instructions, such as `mov rax, rdi`, essentially making them free (zero latency). Notably, Alder Lake's renamer is
