Flexible Software Design Trumps Rigid Domain Models

2025-09-08

This article challenges the popular software design principle of tightly binding code to the domain model. The author argues that over-emphasizing the avoidance of invalid states, such as through strict database schemas and type constraints, limits software flexibility and makes it difficult to handle inevitable real-world exceptions. Using state machines and foreign key constraints as examples, the author demonstrates how to allow arbitrary state transitions while keeping the core design simple, thus improving software adaptability and maintainability. Ultimately, the author advocates for allowing the representation of some invalid states in user-facing software to cope with evolving requirements and unforeseen circumstances.

Linus Torvalds Cracks Down on Useless Links in Git Commits

2025-09-08

Linus Torvalds, the creator of Linux, is fed up with pointless "Link:" tags in Git commit messages for the Linux kernel. He finds that many of these links simply redirect to the same patch already present, offering no additional context. Moving forward, he'll be stricter about accepting pull requests with these useless links. While he appreciates links for multi-part patch series cover letters, he's pushing for better automation to filter out valueless links, even suggesting AI could help determine a link's usefulness. He urges developers to ensure any "Link:" tags add genuine value, avoiding time-wasting redundancy.

Musl's Default Allocator: A 7x Performance Nightmare!

A real-world benchmark revealed a shocking 7x slowdown using Musl's default allocator compared to alternatives. The author strongly recommends all Rust projects immediately switch to a different allocator like mimalloc or jemalloc by adding a few lines of code to their `main.rs`. The root cause is thread contention during memory allocation, worsening with more threads or allocations. Switching is advised even if not targeting Musl or for single-threaded programs. The author explains the reasons for using Musl (cross-compilation and static executables) and details the discovery process. Numerous other projects have encountered this issue, with benchmarks on various core counts showing slowdowns up to 700x! The author concludes by urging a switch to a more performant allocator.

Code Formatting Solved in the 80s? The Case of DIANA and the Rational R1000

2025-09-08
Code Formatting Solved in the 80s?  The Case of DIANA and the Rational R1000

In the 1980s, developers working on the Ada compiler used a Descriptive Intermediate Attributed Notation for Ada (DIANA) intermediate representation (IR) instead of plain text source code, effectively solving the code formatting problem. The compiler and IDE directly manipulated the DIANA tree, allowing users to customize the code display format without worrying about spaces or tabs. This enabled incremental compilation, refactoring, and fast integration. The author uses this example to reflect on how code formatting remains a problem for programmers today, encouraging exploration of more advanced solutions.

Stop Shipping PNGs as Game Textures!

Still using PNGs for game textures? This post explains why that's suboptimal and introduces a better approach. While PNGs are great for interchange, they weren't designed for texture data and lack support for GPU-compatible texture compression (like BCn), leading to slow loading times and high VRAM usage. The author advocates for texture formats like KTX2 or DDS, providing an open-source tool, Zex, to convert PNGs to KTX2 with BC7 compression and zlib supercompression. Tips on pregenerating mipmaps and automating the conversion process are also shared, along with a recommendation to use Tacentview for viewing texture formats.
