Many of us have a rough idea of what side-effects are and a vague sense that they're bad. It's a shame we're not more precise about it, because when you really understand side-effects you have an excellent new lens through which you can judge individual blocks of code, larger architectural patterns, and even whole system designs. So let's start by clarifying our understanding of what side-effects are and how to spot them. We'll see how easily they arise, leaving code that's harder to understand, harder to test and harder to decouple. Then we'll look at tools and techniques for eliminating those side-effects where it's possible and managing them where it isn't. Finally we'll zoom out to see how those ideas get expressed in every field of computing, yielding fundamentally different approaches to programming language design, DevOps, system architecture, and database design. There's an iceberg of complexity hiding in your systems' side-effects and by the end of this talk you'll be able to spot it and start tackling it, rethinking the way we deal with data and the systems around it."
 

Some codebases are nicer to work with than others. This is true for applications, services, libraries, frameworks, even programming languages themselves. Is this a purely personal choice or are there universal characteristics of software that can make code a joy to work with? Daniel has been thinking about this for a long time, especially since he poked a stick at the SOLID principles for fun a few years ago and people came after him with pitchforks.

Extended Abstract
His recent post about why he feels SOLID is outdated ended up on the front page of Hacker News! Now he has codified his thoughts into his own pithy five-letter acronym, CUPID: Composable, Unix philosophy, Predictable, Idiomatic, Domain-based. Why these characteristics, what do they mean, and why should you care? Can they improve your coding experience or is this just more programmer navel-gazing?

Everyone wants to innovate, the question is how do you change your environment to support innovation?
Gabrielle will introduce the innovation imperative; why innovation is a necessity, a look at the disruptors threatening the fundamental ways we do business, and how to create a sustainable innovation strategy. 
We then go to the mean streets of Chelsea, London and meet Riccardo Mariti of Riccardo's restaurant. Riccardo will show you need to disrupt your business before you get disrupted and the importance of building continuous innovation into everything you do. Expect many stories and an interactive Q&A

For most people, AI means robots taking human jobs or China’s surveillance of its citizens. Despite the hype around it and its image of progress, the real workings of artificial intelligence are not widely understood. Companies are already implementing a web of algorithms to optimize manual business processes. Most of the time, the larger IT organization is not included on the journey. This talk is an overview of how IT leaders can center the development of human teams in a world that is increasingly optimized by algorithms.
