META REVEALS THEIR SERVERLESS PLATFORM PROCESSES TRILLIONS OF FUNCTION CALLS A DAY

Meta’s internal serverless platform called XFaaS processes trillions of function calls a day thanks to unique software optimizations. This article describes how XFaaS works and the optimizations Meta has performed to make its platform efficient, such as utilizing just-in-time compilation. XFaaS solves common problems that serverless platforms face, like lengthy cold start times, high load variance, and overloading downstream services, with creative solutions. The platform offers lessons for public Function-as-a-Service (FaaS) providers, like AWS Lambda, Azure Functions, and Google Cloud Functions. It is useful for software engineers working with cloud providers to understand how to make serverless functions more efficient.

NEXT.JS APP ROUTER MIGRATION: THE GOOD, BAD, AND UGLY

The Next.js App Router allows for better flexibility of layouts, loading states, and initial data loading on the server. However, it has drawbacks such as the need to add client-side fetching for live UI updates, server-side errors being easily hidden, the inability to implement route exit animations, and issues with routing type safety. The Next.js App Router may not be fully production-ready yet as it still has memory leaks and lower dev server performance.

HOW TO DESIGN RESILIENT AND LARGE SCALE DATA SYSTEMS

Building a data system is incredibly complex, as each team, product, and company has vastly different needs and requirements.

HELL IS OTHER PEOPLE: PERFORMANCE MANAGEMENT AT BIG TECH

The primary reason for performance management in Big Tech is to address employees' concerns about fairness and equity in compensation.

However, this approach often leads to overly positive and vague feedback, making it challenging to differentiate between employees. Ultimately, managers still play a significant role in making decisions about promotions and layoffs, leading to perceptions of favoritism or opaque committee decisions.
