Release It Book Club Relaunch

I’m relaunching the Release It! book club on Kook Book Nook (yes, the name is kooky on purpose), which is a Discourse forum I set up specifically for book clubs. I felt a forum would be a better format for the types of discussions I want to have with you about this book. Come join me and let’s learn from each other and have some fun along the way.

Release It Book Club Chapter 3: Impulse and Stress

Chapter 3 of Release It! has some interesting definitions that I hadn’t considered as deeply before. Nygard notes that the following two terms come from mechanical engineering.

Impulse is a “rapid shock to the system.”

Stress is “a force applied to the system over an extended period.”

What do you think of these terms? Have you felt the need to differentiate between these two types of load in your work?

Release It Book Club Chapter 2 Case Study

Chapter 2 of Release It! is a case study of an incident that occurred which brought down an airline’s entire check-in system. It took three hours to recover, and was caused by leaking connections from a database connection pool. Nygard’s conclusion from the case study is that perhaps this issue could have been caught with more testing, but even so it’s impossible to catch every such defect. And therefore you have to prepare your application to survive such issues. Do you see any problems with this conclusion?
