Bespoke software is gaining traction as companies seek tailored solutions rather than generic, off-the-shelf software. The author references a common sentiment among Google engineers who recognize that their success stems from custom software designed to work seamlessly with each other. This stands in contrast to the "Not Invented Here" syndrome, where organizations often settle for generalized software that doesn't quite fit their needs. The article highlights the inefficiencies of such generalized solutions, which often require companies to pay for features they don’t use. The author shares personal experiences with LLVM, a comprehensive codebase that, despite its quality, presents challenges due to its complexity. This complexity arises from the need to support numerous features, formats, and systems, making it difficult to navigate. In response, the author created µld, a simplified linker in Rust, focused solely on a specific target (ELF, x86_64) with a minimal feature set. The process was surprisingly quick, taking only 1-2 days, indicating that smaller companies can now develop bespoke software without the vast resources of larger firms. The piece emphasizes the potential of large language models (LLMs) to facilitate this shift towards bespoke software development. LLMs can help streamline the creation of custom tools, enabling organizations to build solutions that address specific problems effectively. The author believes that as companies begin to shed legacy systems and embrace tailored software, they will end up with smaller, more manageable codebases that integrate better with their existing infrastructure. This approach promises to democratize software development, making it accessible for companies of all sizes.
