This course covers debugging and the different techniques that help developers efficiently trace bugs in programming. It also includes guidelines and tips for software developers who must debug applications in production environments. 

You’ll start with introductory concepts of bugs and their life cycle. Next, you’ll cover the basic debugging techniques such as tracing code paths, reproducing the issue, logging, and knowing what to chase. In the next section, you’ll learn debugging techniques for multithreaded applications and the art of finding bugs in crashes and hangs. By the end of the course, you’ll gain knowledge about scaling issues, troubleshooting environments, monitoring, and building debuggable systems.

After completing this course, you’ll have detailed knowledge of debugging and its different techniques. It will also help you enhance your debugging skills, which are applied throughout the life cycle of software development.

The process frequently restarts after crashes.

The process consumes more memory than other processes.

The process's memory usage increases monotonically.


What could be a possible indication of a memory leak in a process?

What could be a possible indication of a memory leak in a process?

A thread that consumes excessive CPU resources.

A thread that runs indefinitely without completing its task.

A thread that is created but not properly managed by the program.

A thread that communicates with external systems.

They can significantly slow down the underlying process causing performance issues.

(True or False) Shared libraries are loaded into memory at compile-time.

**(True or False)** Shared libraries allow multiple programs to share the same code in memory.

(True or False) Shared libraries allow multiple programs to share the same code in memory.
