David Heinemeier Hansson·2yOptimize for bio cores first, silicon cores second
Ruby on Rails has been championed for its ability to enhance programmer productivity by trading off compute time, which has become increasingly economical compared to programmer costs. The focus should be on optimizing the expensive biological cores (programmers) over the cheaper silicon cores (computers). While optimizing software for maximum hardware efficiency can be admirable, it often doesn't make economic sense for most business software, where high-level languages and tools can drastically improve productivity and profitability.

System Design Codex·2yAirbnb's Migration from Monolith to Services
Airbnb transitioned from a monolithic Ruby on Rails application, known internally as the 'monorail', to a Service-Oriented Architecture (SOA). Initially suitable for agile development, the monolith became difficult to manage as the company grew. The new architecture consists of data services, derived services, middle-tier services, and presentation services, each with specific functionalities. The migration of reads involved dual reads and response comparison, while writes used a shadow database. Key lessons from the migration include investing in common infrastructure, simplifying service dependencies, and recognizing that moving to services involves cultural as well as technical changes.
