[Online Only] System Design Discussion

Join us for the system design discussion every Friday at 4 pm.
The agenda is here. Each time, we choose a topic or continue a previous topic and pick one or more volunteers to design this system. We follow the pattern in actual interviews without a time limit.
You can learn more from the discussion if you are familiar with system design. Here are some good websites:

• System design primer
• Designing Data-Intensive Applications
