Infrastructure as code using Terraform, by Hugo Peixoto
We use git to keep track of what changes we do to our code, and why we do them. Some use Chef/Salt/Puppet to keep track of server installations. I use terraform to apply the same process to manage my AWS accounts, both personal and professional.
This doesn’t apply only to your standard cloud providers (AWS, GCP, Azure). I also manage resources on Heroku, Netlify, Fastly, GitHub, Gitlab, and other tools.

A serverless case study with AWS, by Luís Miguel
A full-fledged CMS can easily keep records of tasks input by users, process those tasks into a queue, communicate them to a job factory, and notify users of the results. We decided we didn’t want to manage a full CMS just for that, going serverless was the perfect alternative.
How Ember.js revamped their infrastructure, by Ricardo Mendes
The Ember project has many associated websites, the guides, the deprecation guides, the blog, the API documentation, and the main website itself. These were built over the years as needed and used a mishmash of technologies (middleman, embedded Ember, standalone Ember), which made it hard for both maintainers and new contributors to the project. To take advantage of the Ember knowledge and skills in the community, we started moving projects to Ember. In this presentation I will be covering how we are using JAMstack practices to accomplish this migration.

Elm, by Décio Ferreira
Elm is a functional language for reliable webapps, with a very strong emphasis on usability, performance, and robustness.
- No runtime errors in practice. No null. No undefined is not a function.
- Friendly error messages that help you add features more quickly.
- Well-architected code that stays well-architected as your app grows.
- Automatically enforced semantic versioning for all Elm packages.
By the end of this talk I hope you will be able to create your own web application in Elm, understand how it compares with other projects like React as a tool for creating websites and web apps, but also understand the core ideas and patterns that make Elm nice to use.

Living inside GNU Emacs, by André Alexandre Gomes
Today’s technological world is both exciting and alarming.
Exciting because we have the tools to solve the challenging problems of our overpopulated planet. The vision of a connected, peaceful and fair world feels closer than ever.
Alarming because tech companies provide tons of malware that people greet without questioning - exchanging their freedom for a fake sense of pleasure and a fake sense of productivity.
In this talk, I will show that GNU Emacs is the perfect environment for a focused and free life in a world full of corrupted people and bullshit.

How to get over 300GB of 3D data to the web in real time, by José Ferrão
At UNO Digital we develop solutions for the oil and gas industry. One of our products is world scale visualization for geospacial data, point clouds and CAD models. This information is combined with asset management and monitoring data from our platform to create real time visualizations of production plants. In this talk we will present the challenges we faced while trying to deliver over 300GB of 3D data to the web at record time.

Thriving through the hype cycle: an Ember.js story, by Ricardo Mendes
The front-end development community has been through a fair share of hype cycles in the last ten years. In this time, we have seen libraries and frameworks come and go, sometimes even disappearing completely like batman.js.
In this talk we will cover how the Ember.js project has managed not only to keep up with the hype cycles, but to continually push the framework and the web forward and bring its users along. We will close off the presentation by talking how this culminates in the concept of editions, the first of which is Ember Octane.

Email me maybe, by Pedro Coelho
Build your own email server! First we’ll see how email works both in theory and in practice, and the stuff you’ll need before building your own server. We’ll then go through the steps to build one ourselves, hopefully see it in action, and in the end we’ll discuss a bit whether this is a good idea and some peculiarities you may find along the way.

Home automation for tinkerers, by Abílio Costa
Home Automation seems to finally be spreading and growing, with a lot of new products getting to the market with affordable prices. Unfortunately, many of those products use their own proprietary interfaces, so we end up with isolated products that don’t talk to each other, and that rely on cloud-based services (which may be unreliable or slow due to network conditions).
Fortunately, there are many ways to make some of these proprietary products work locally, interact with each other and centralize them, allowing us to control and manage them from a single service, instead of using a different app for each device. In this talk, we will discuss some of the ways to do that using open-source software like Home Assistant. We will also take a look at some of the most common technologies used in Home Automation, and even how to get rid of proprietary firmware and use open-source ones!

React Best Practices, by Luís Cardoso
React is one of the most used libraries for web development. However, because it’s so widely used, the library evolves fast and sometimes we don’t get the most out of it or we are not familiar with new patterns and best practices. This talk gives an overview of the current best practices and caveats to watch out for.

Moving from PostgreSQL to RethinkDB, by Guilherme Pereira
Nowadays, we need to ensure that applications are operating 24/7, and PostgreSQL does not support master-master replication (only through third parties, with some limitations).
With this in mind, I will talk about migrating an application from PostgreSQL to RethinkDB. In a technical talk, I will present the issues I encountered, as well as a performance analysis between both databases.

Real-time Desktop Capture, by João Paulo dos Santos Portela
Sometimes you need to automate desktop capture, but how do you do it? Doesn’t video encoding have a big impact on performance? Aren’t most desktop capture applications GUI based?
Doing desktop capture and encoding on windows with minimal performance impact can certainly be a challenge. Fortunately there are plenty of technologies and libraries to help us. In this talk we’ll explore what’s out there and how an open source project helped us deliver a high quality solution.

Introduction to Swift, by Jaime Paulo
When talking about programming languages, Swift is the new kid in Apple’s block. In this session we are introducing Swift from an iOS developer’s perspective and how it helps build more reliable code compared to its ancestor Objective-C while crushing some myths along the way.
But, is it mature enough? XCode. Using Swift in production and in building apps where Obj-c meets Swift.
Now in version 2.2, we will also talk about where we are going and how open sourcing Swift enables for new interactions with the developer community such as language improvement and other applications of the language.
