Linux kernel upgrades risked introducing latency regressions across Meta's ad serving fleet, which operates at scale where milliseconds of latency degradation significantly impact ads performance.
Meta needed to maintain and advance Python as a critical language across its engineering infrastructure while supporting the broader open-source community that sustains the language.
How to design and manufacture ultra-narrow batteries that fit within the temple arms of smart glasses while providing sufficient power for cameras, speakers, AI workloads, and displays.
Meta needed to automatically identify and remediate performance inefficiencies across their massive infrastructure to reduce power consumption and free up engineering capacity.
Meta needed to modernize WebRTC across 50+ use cases while maintaining synchronization with upstream open-source development, avoiding the drift that typically occurs when large projects fork internally.
Safely deploying configuration changes at scale while minimizing the risk of widespread failures caused by faulty configurations.
Designing high-quality, sustainable concrete mixes that are produced in the United States while optimizing for performance characteristics.
Meta needed to automatically optimize low-level infrastructure and kernel-level parameters for AI ranking models to improve performance without manual tuning.
