The Pony Express and How Technology Moves Fast

It’s been said many times – technology moves fast. As do the philosophies behind it. This isn’t new – the Pony Express lasted only 18 months before being replaced by telegraph. Why is turnover so fast? What are the benefits and pitfalls of this turnover? Where is the value in what we do?

This talk will take a look at certain aspects of tech to see where we find value, where things have been built on shaky ground, and where strong foundations will move the industry forward. We’ll take a look at:
– Philosophies and Fads (Agile, DevOps, BDD/TDD/Shame Driven Development)
– Programming Languages: Emerging vs Established
– Hardware, the Cloud, Containers, and Serverless

Each step will examine what we have learned from our past, what it means now, and where it may lead moving forward.

Proactive Programming

The feedback loop is one of the most important parts of programming. We write tests and try to mitigate all possible problems, but until we deploy our code, it’s hard to tell what “works” and what doesn’t. In this talk, we’ll discuss methods used to ensure everything works the way it should before deploying to production.
