The missing user stories

Data: You keep using that word

structured data, dynamic data, big data, data driven..... we hear about data all the time. But what is "data" exactly? The term is frequently used, yet is rarely defined or thought of - and it turns out the answer to "what is data" is not simple at all. "Data" is a software concept which describes real world properties and information - and there must exist some process of creating "data" from those properties. This "data modeling" process is one of the most fundamental and complex exercises in software engineering but it's often overlooked and taken for granted. In addition, once you have data it must be actively maintained. Corrupted is relatively easy to detect, but how do you know if you are _missing_ data? This talk aims to review what "data" is, how it is created, defined and maintained show real world examples of the complexities, problems and solutions of these often ignored processes.

Practicalities of Managing Large Clusters

"Operations": You keep using that word, but I don't think it means what you think it means

#DevOps, #NoOps, #serverless - every few years yet another movement to get rid of those pesky Ops engineers no one likes pops up. But like cockroaches, we can’t seem to be able to get rid of the buggers. Can it be we just don’t really understand what “operations” is all about? When people hear “Operations”, they think of managing servers, of automation, CI and deployment pipelines. But Operations is not about any of that - operations is about making the machines you built/purchased/programmed earn money (or whatever the goal of the organization is). Making your business work is what operations is about. This presentation introduces the principles and history of Operations Engineering, the challenges and responsibilities of practitioners and the transformations IT Ops world is experiencing in recent years.
