BASH/command-line scripting is a powerful tool. However, many of its behavior is somewhat counter-intuitive and I’d argue adversarial. I will showcase some these unexpected results by incrementally hardening a simple script. Failure is an Option #!/bin/bash echo "Launching rocket!" ROCKET_TO_LAUNCH=$(get-available-rocket) echo "I'm still running even though a command failed!" echo "Launching rocket $ROCKET_TO_LAUNCH"

“The Art of War” is a book that stood the test of time. And for an excellent reason: what better strategy there is than where it’s a matter of life and death. We are always looking for the latest research or discovered strategy that serves us best. But as different…

In a sense, it’s the world beyond the CI/CD/DevOps/GitOps, where some conventional techniques and characteristics are abstracted away and broken down in a generic form. What makes this book special is that it…

“Mastering Algorithms with C” is an excellent choice for learning many algorithms for C programmers.
