However skilled the developers are besides their focus on business and personal objectives, climate change and a growing need of accountability of public services is making emerge a sense of urgency, leading citizens to act upon the most mundane aspects of everyday life. Nowadays, with the range of tools at our disposal and higher distribution of skills, technologists are a key actor in accelerating the change we need to see: making tangible where the market renders expensive and stuck to roadmap powerpoints; making available working solutions where government is rendering complex and bureaucratical.

Adjacent to the sense of urgency is the need to enable processes that can take-on creative problem solving, with a focus on human needs and in an environment where collaboration can thrive, regardless of skills, background and experience. Going beyond the state-of-the-art, this presentation aims to take the Civic Tech theme a step forward and contribute towards sparking a local community of practices that could build on previous experiences in Berlin and make them touch ground in Faro.

Embedded in the grievous realities of the Portuguese wildfires and as a concrete example of civic tech, Inês Boski's talk will focus on presenting Fénixhack, a campaign-hackathon project for developing solutions to a better wildfire management. "How to mobilize people behind (tech) solutions development?" and "Is tech a strong prospective ally of the better wildfire management cause?" will be just some of the questions this talk will aim at raising. More information about the project: fenixhack.org.

This talk dives deep into a topic that, sadly developers don’t know enough about: database indexing. Indexing is much more nuanced than throwing an index at every column in your WHERE-clause and hoping that it sticks. Since poor query performance can be the difference between an application feeling snappy and being literally unusable, it is imperative that we as developers know how to properly index a database.

We will take a look at how indexes work internally, common pitfalls when designing indexes and what all of this means for us in practice.

After this talk you will be well equipped to create well-designed indexes and confidently debug slow queries in your applications.

Nowadays it is becoming more and more common to have a Single Page Application-frontend that is powered by JavaScript, e.g. using React, Angular or Vue, and your PHP-application solely providing a RESTful API for it. Using Symfony 4 and Flex it is easy to setup your Symfony application for this purpose and build an API that is solely dealing with JSON data. In my talk I want to give an outline on how to manage a project made up from separate frontend and backend, focusing on how to prototype a basic Symfony API-application from scratch. The aim is to teach you what most API-centric bundles are doing under the hood to better grasp how to extend or modify them and how to debug problems.

This talk gives a practical introduction into the main concepts of AWS Lambda explained along the popular quiz game “Denk-Fix”. Additionally, we’re going to demonstrate how Lambda functions can be integrated with theAWS services DynamoDB and S3.

Alexandra, Matthias, and Prasanna have been working on a project with micro frontend architecture for the past year.

This project involves 4 teams distributed over two countries - Germany and India, each of the teams delivering one or several micro frontends that are consolidated into one product in the browser.

This talk is based on our practical insights into micro frontends using React and Redux. We will discuss the differences between this technique and micro-services, our approaches in solving the common issues, the advantages it offers and the challenges it brings.

Maintaining a JavaScript software project, be it open source or not, can be a ton of work. There is the fun work of developing new features , fixing a bug or refactoring a messy chunk of code but those are always followed by chores like releasing new versions or updating some dependencies. But worry not, there is help out there. I’ll show you the benefits of semantic versioning and some cool bots, such as Greenkeeper and semantic-release, that will do these chores for you!

PHP developers live in a brave new world: in times of conventions over configurations, fullstack frameworks, SOLID principles, dependency injected services, CI-pipelines, docker containers, Vagrant boxes, automated testing and rolling deployments, package managers and SCRUM processes the amount of skills needed to develop web apps grows with O(n^2). Everything gets more complicated, takes more time and adds costs for the client. Do you sometimes wish back the old times of “dirty” coding and plain FTP upload hacks onto the live server? Who are the winners and the losers of this development? Is the growing effort really worth it? Clean-Phil and Dirty-Daniel try to answer these questions and present their points of view with examples, live coding and a lot of humor. Who will win that match? You decide!

Confidently deploying with GitLab CI and kubernetes. Using automated builds, tests and deployments saves time and nerves. In this talk, we will show you how we have adopted GitLab CI and Kubernetes to stop worrying and deploy with confidence.

While it's fun to write little one-off utility scripts, sometimes you need to write real console apps. One that takes arguments and plays nicely with UNIX conventions for input, output or error reporting. In this talk, we will be using Laravel Zero (http://laravel-zero.com), a micro-framework that leverages an unofficial and customized version of Laravel to provide an elegant starting point for your console app. You’ll learn about the philosophies and ideas behind the framework. We’ll also cover the most important features of Laravel Zero, such as the optional installation of Laravel Eloquent, the usage of Laravel Scheduler or the integration with Collision.

This talk will include a 20 min live-coding session, where you will learn how to leverage Laravel Zero to make console apps with a real practical example. After this talk, you’ll be able to deliver console apps at warp speed. Your console app can be used for any recurring task, such as cronjobs, imports, or other batch jobs. You will be able to leverage Laravel Zero, a micro-framework built on top of Laravel components, to use your favorite features of Laravel to build a structured an elegant command line app.

Elixir is great, so clearly we'll all rewrite our applications in Elixir. Mostly, you can't and shouldn't do that. This presentation will show you another path. You'll see how at Liefery, we started with small steps instead of rewriting everything. This allowed us to reap the benefits earlier and get comfortable before getting deeper into it. We'll examine in detail the tactics we used to create two Elixir apps for new requirements, and how we integrated them with our existing Rails code base.
