If you have a collection of photos that your users can download in a zip file, you have many different options for the user experience. Most of these involve the user to wait for the zip to be produced in the background. In the presentation, I will take you through the steps of creating the zip fly on the fly, using reactive programming with backpressure in micronaut. Doing it this way, we can limit the memory usage, even with many clients downloading on a slow connection. An introduction to reactive programming and backpressure is included!

'Develop IoT solutions with Kotlin is possible thanks to the incorporation to Kotlin as a first class programming language to Android and the becoming of Android Things, an optimized version of Android for embedded devices. This talk is looking for explore the aspects around IoT projects, Hardware, Security, Server Side, Data Analysis from the hand of Android Things and Kotlin.' - 'The Internet of Things is a technology that has been echoing for some time. Arriving to generate interesting and attractive solutions. It usually happens that those who develop this type of solutions know about the Hardware, or they only have knowledge of the Software side. This talk seeks to explore all those aspects around IoT in the hand of a real project for monitoring fishbowls (something that you can implement at home).' - 'In the hardware side, we will use sensors and different technologies for handle the information obtained from these (Raspberry PI, Arduino, etc). Since we want to show how to use Kotlin for develop IoT solutions, we will use Android Things with Kotlin and Raspberry PI.' - 'The server side, using Serverless or IoT cloud solutions, options to analyze our information. Finally, is important take some considerations over the security aspects in IoT projects, although there are not yet 100% solid solutions, there are already efforts to solve this.'

Android developers are facing a common problem: how to test our applications on many devices without sacrificing too much time or money? How to build and test automatically our applications for each commit? How can we find those devices inside the company, whatever its size may be? Could there be a directory somewhere that lists those available devices? Could we use a device remotely and share it with other developers as if it were in the cloud? What if you could answer all these questions with the help of a low cost device farm that fits into a pocket? A pocket full of clouds... Poddingue, our proposal, aims to tackle this problem thanks to Docker, HypriotOS, Armbian, Gitlab CI and OpenSTF. It’s an internal solution made of OSS readily available, but it has not yet been publicly announced as a whole. This is a feedback about an idea on its way to production, a long journey full of different feelings : horror, happiness, suspense, boredom... This presentation won’t be too technical ; it is opened to anybody who has an interest into Android, exotic hardware or continuous integration, as long as you can stand a bad sense of humour. At the end of the talk, you should know how to build your own cloudy pocket farm of Android devices and how to use it to test your applications within your ci pipeline.

Kotlin, a modern language bursts into the community when developers have been perfecting what they call Clean Architecture for years, some potions and spells with which to increase the power of testability and become independent of evil external agents and cruel frameworks.

Micronaut is fast at startup time but... how faster is it? If you want to know the startup time, memory consumption comparing with other frameworks and using GRAALVM this is your talk.

As Java is an object-oriented language that inherently supports the imperative programming style, asynchronicity presents a challenge that can turn the code into nightmare. One way to deal with the complexity of asynchronicity is to introduce reactivity onto the coding level (reactive programming), and/or to handle it on the design and architecture level (reactive systems design).

Accelerating CI has dramatic effects: tightening the feedback loop for developers, delivering changes to production faster, and reducing CI resources costs. In this talk, we'll see different patterns to optimise CI: - Collecting key metrics to detect regressions, pinpoint bottlenecks, and confirm improvements - Setting up an efficient pipeline structure - Establishing environmental build agent patterns - Leveraging caches to avoid unnecessary build work Most of the talk will be based on our experience while developing Gradle Enterprise in a highly productive team of fifteen people.
