Cloud Automation with Low Code Tools

Nick Ellis

with Nick Ellis

Why reinvent the wheel? Or a trainload of wheels? Developers spend a lot of time creating integrations that already exist and are easy to access. A quick demo of how automation can extend developer capabilities quickly, easily and cheaply!
 

Why Rust?

Edd Barrett

with Edd Barrett

For longer than I have existed, memory errors have plagued systems programming. Although many such errors are benign, sadly many end up being security vulnerabilities, or worse, exploits. In this talk, I will discuss how a security exploit is born, and how the Rust programming language tries to prevent them.
 

Issue with tracking? Fail that build!

Steve Coppin-Smith

with Steve Coppin-Smith

The analytics strategy must be a primary citizen of the software delivery process in a data driven business! This talk will include a live demo of extending the Nightwatch automated testing framework to uncover and resolve issues in tracking code that would have otherwise hit production.

How to 10x learning a new programming language

Raymond Coulstock

with Raymond Coulstock

What is simplicity and why do we value it so much? How does it relate to complexity? When is complexity good and when is it bad? How does simplicity differ from ease? As we examine these questions we'll find that the situation is not quite as simple (!) as it might first appear. In the course of the discussion we'll come up with a mental model for framing problems that we can apply to many things - but we'll particularly look at how we can apply it to our designs and code. We'll also look at how some programming languages help us more than others in our drive towards simplicity.

Telephone Systems and Voice over IP

Bob Eager

with Bob Eager

The speaker will talk about his experiences with a gradually evolving SOHO telephone system, starting with a single POTS (landline), through ISDN, to the current VoIP solution, and the eventual removal of the original telephones. The majority of the talk will concern the use of the open source Asterisk platform to provide numerous facilities (including one or two quite unusual ones) in a large, rambling house used also as an office for part of the time. This will include an introduction to VoIP for beginners. Costs and savings will also be considered. There will be time for questions and discussion.

This is a case study from Holiday Extras on our Bulgarian and UK remote teams over the last 18 months. We'll be sharing the change curve in attitudes and how not only the scrum masters had to get used to remote workers, but the dev team had to get used to remote pair programming. We'll be delving into the challenges we faced and the changes for the better.
 

Gamification in the Real World

Stuart Stobie

Gamification. Just a buzzword? Or is it a silver bullet for businesses in the 21st century? Unsurprisingly it’s neither. Gamification aims to make the tedious entertaining but making anything fun is not as simple as it sounds. In this talk we'll take a look at the misconceptions surrounding gamification, the fascinating psychology behind it and the lessons we really should be learning from the games that inspire it.
