WHY WE USE OUR OWN HARDWARE AT FASTMAIL

Fastmail uses its own hardware for email services because it allows for cost optimization and long-term planning over the dynamic scaling offered by cloud services. This approach allows for more efficient hardware usage, where equipment can be used for 5-10 years. Fastmail recently upgraded to a ZFS-based NVMe SSD system, leading to big performance and space savings through compression while eliminating the complexities of traditional RAID setups.

TRANSLATING JAVA TO KOTLIN AT SCALE

Meta undertook a massive project to translate its Android codebase from Java to Kotlin, exceeding the halfway point despite having one of the world's largest codebases. To manage this at scale, it created the Kotlinator, a tool that automates the conversion process using JetBrains' J2K, supplemented by extensive pre- and post-processing steps to handle complexities and custom frameworks. This automation involved addressing build speed issues and creating a headless version of J2K to run conversions remotely, integrated with Meta's internal code review system.
