Previous: Part III, Chapter 9 - The Generator Next: Final Thoughts and Key Takeaways

The final chapter. After 1100+ pages, we get the ending.

The Rescue

Straight-up action sequence. Dagny walks up to the guard at Project F, where Galt is being held, and basically tells the guy to let her in or she will shoot him. The guard panics. Cannot decide. Keeps saying “Who am I to choose?” and “I’m not supposed to decide!” Dagny counts to three and shoots him.

Previous: Batch and Streaming Pipelines

Book: AWS Certified Data Engineer Associate Study Guide Authors: Sakti Mishra, Dylan Qu, Anusha Challa Publisher: O’Reilly Media ISBN: 978-1-098-17007-3

Chapter 9 is the practice exam. 42 questions covering all four domains of the DEA-C01 certification. Stop reading, start testing yourself.

What the Practice Exam Looks Like

42 questions. Most are single-answer multiple choice. Some ask you to select two or three correct answers. Multi-select questions always tell you how many to pick.

Previous: Part III, Chapter 8 - The Egoist

Maybe the most disturbing chapter in the entire book. Also the most absurdly, painfully ironic. Rand takes the core thesis of Atlas Shrugged and compresses it into a single scene you cannot forget once you read it.

Dr. Stadler’s Final Delusion

Dr. Robert Stadler driving through the night across Iowa. He has gone completely off the rails. After Galt’s broadcast, Stadler panicked. Decided his only option is to seize control of Project X – that massive sound ray weapon built from his own research – and use it to establish himself as some kind of feudal lord over the countryside.

Previous: Data Governance

Book: AWS Certified Data Engineer Associate Study Guide Authors: Sakti Mishra, Dylan Qu, Anusha Challa Publisher: O’Reilly Media ISBN: 978-1-098-17007-3

This is the chapter I was waiting for. After seven chapters of theory, services, security, and governance, Chapter 8 finally says: “OK, build something.” Two complete pipelines, end to end, with real code and real AWS services.

If you learn by doing, this chapter alone is worth the price of the book.

Previous: Part III, Chapter 7 - This Is John Galt Speaking

One of the most absurd and one of the most real things Rand ever wrote. The government captures the man who told them exactly why their system is failing. Their first move? They ask him to run it for them.

The Aftermath of the Speech

Right after Galt’s radio speech. The government officials are standing around the radio, stunned. Mr. Thompson asks “It wasn’t real, was it?” Like a kid who watched a horror movie and needs someone to tell him it was fake.
