    The 2 Types of Programmers

    There are two primary types of programmers: craft-based and result-based. Craft-based programmers focus on code quality, maintainability, and optimal solutions, often seen among open-source maintainers and low-level programmers. Result-based programmers prioritize speed and end-product functionality, commonly found in startups and content creation. Successful programming practices often require a balance between these two approaches to meet both performance and business goals.

    How Uber Handles TRILLIONS of Transactions

    Uber handles trillions of transactions by evolving from a monolithic application to a microservices architecture using Postgres and MySQL. They developed their own immutable ledger system called Ledger Store, which sits above existing NoSQL databases, ensuring the integrity of financial transactions. Key features include sealing, manifest for security, and the use of Apache Kafka for real-time data streaming. They managed a complex database migration with minimal disruption by employing strategies like checkpointed data processing and the Shadow Rider system for simultaneous database operations.
