An interesting op-ed from Dr. Egginton at John Hopkins University highlights some efforts underway in the US to declare learning to code the equivalent of learning a new language.
Both are equally important. Languages help with understand and communication and everyone should learn as many as they can.
But programming computers is not the same exercise. Programming languages are all about logic and structure. But similarly, anyone in cybersecurity should learn at least the basics of coding.
The reason is the same as learning a second (3rd, 4th, etc.) human language: understanding. Learning to code (even just the basics) will give you a better understanding of the trades off necessary in cybersecurity. A better understanding of the challenges of successfully building and running a system that solves problems for customers. A better understanding of your colleagues.
When it comes to cybersecurity, a broader perspective is a better perspective. Learning additional skills within the IT sphere is never a wasted effort.

![Can We Improve How Netflix Handled Failover Using DNS In 2017? (Reaction)
In late 2017, Netflix did an AWS This is My Architecture video. It was one of the first. In the video they explained how they tackled the problem of failing over when disaster struck.
Specifically, they drilled down on a clever use of DNS records to create a very flexible system that allows services to continue in the event of some pretty significant disaster.
Few companies operate at Netflixs scale (even their scale back then) but this technique is broadly applicable for any team that needs to failover in the event of either disaster or even a simple failure.
Now, a few years later, I react to that video and see whats stood the test of time, what could be done simpler given todays technology, and generally critique the design against the AWS Well-Architected Framework in a mini AWS Well-Architected Review.
