# Assignment: Concurrency Bugs
**Due:** Monday, November 10th by 11:59pm

You will identify four concurrency bugs and explain how to fix them.
The assignment is posted now.

## Q&A
**How much should we write in our responses?**  
Enough to explain what the bug is and how you'd fix it, but you don't need to write code or give every minor technical detail.
In most cases, 4–5 sentences is probably enough.

# Lab: Password Cracker
**Due:** Wednesday, November 5th by 11:59pm  
**Late Deadline:** Wednesday, November 12th by 11:59pm

## Q&A
**Can our implementation leak memory if that makes it faster?**  
Yes, as long as you include commented-out code to free the memory along with a note that explains the leak is intentional.

# Discussion: Distributed Systems Basics
**Questions for think, pair, share:**

1. What is a distributed system, and why would we want one?

2. How is communication over networks different from the ways threads communicate?

3. What makes building distributed systems difficult?

*Start by thinking of answers on your own. I will let you know when to start discussion.*
