DESCRIPTION
As developers, we often make things happen but can’t explain exactly how.. Computing ultimately comes down to 1s and 0s, but we seldom think of our work that way. It is the powerful abstractions provided by software that drive technological progress. But what happens when these abstractions become too magic? This talk will explore the pitfalls of “abstraction magic”, and promote the successes that full stack understanding can bring to your projects, and even career.
