There will be no agenda, which sets the stage for the meeting's participants to create the agenda for themselves, in the first 30–90 minutes of the event.

We will begin with short introductions by the organizer and facilitator. They introduce the purpose; the facilitator explains the "self-organizing" process called "open space."

Then the group creates the working agenda, as individuals post their issues in bulletin board style. Each individual "convener" of a breakout session takes responsibility for naming the issue, posting it on the bulletin board, assigning it a space and time to meet, and then later showing up at that space and time, kicking off the conversation, and taking notes. These notes are usually compiled into a proceedings document that is distributed physically or electronically to all participants. Sometimes one or more additional approaches are used to sort through the notes, assign priorities, and identify what actions should be taken next.

Sometimes when I'm writing Javascript I want to throw up my hands and shout 'this is insane!' But I can never remember what 'this' refers to." JavaScript is no toy language anymore and designing in the browser with CSS is far beyond being just en vogue. But with the fast and ever moving ecosystem of native client-side technologies, a lot of questions arise: Which framework is here to stay, and what do web standards have in store for us? Find out as we explore the depths of next generation web applications.

It's well known to all of us that we have entered into the age of big data. The amount of data is growing at an unprecedented rate and there is no signs of it slowing down. Skills and abilities to turn that data into valuable information will bring companies a significant competitive advantage and lay the foundations of their future success. Some of the companies have understood this a while ago, some are just beginning this journey.

Topconf Tallinn's Big Data track will focus on real life case studies that will cover different aspects from the big data life cycle, from storing of the data to searching, streaming, analyzing, visualizing, and handling privacy.

Are you struggling to complete projects successfully and on time and within budget? Or are you just interested in what project managers actually get up to? Then the sessions in this track are for you. They cover everything from ‘hard’ approaches to ‘soft’ skills. Come for the case studies with practical approaches for you to adapt to your specific environment.

Are your software products as valuable as they could be? How well do you actually manage the whole product lifecycle? Come and learn from the case studies that cover everything from marketing to decommissioning. This track is not just for product management roles but also for developers who want a better understanding of what product management entails.

This track features topics related to Java language itself, modularity, performance and technical design. It also covers wider, JVM landscape of other languages, tools, libraries and best practices. We’ll bring the best of Java ecosystem with all the awesome innovation to this track.

Reactive architectures are common in various domains already but haven't reached the mainstream quite yet. Looking into the 2017 generation of reactive programming models and frameworks, we're going to discuss the design challenges as well as the infrastructural challenges, with a focus on the Reactive Streams specification and how it facilitates modern server-side application architectures.

As developers we love writing code. But reality is that we spend more time maintaining and modifying other people's code than writing our own code from scratch. Can we make it more pleasant? Can we reduce time spent so we can do things we enjoy?
This track will look for what developers can do to improve software quality, maintainability, testability and related “-ilities”. We'll see what tools and methologies could supercharge our testing abilities as well as how to improve these skills as well.

Trainings and Workshops are your perfect opportunity to spend a full day or even two full days to discover and learn in depth from an expert.

Effective developers have a T-shaped competence profile. In other words, in addition to their core development competences, they also have basic knowledge of the other disciplines with which they interact. Such as IT operations. This track provides developers with a better understanding of what IT operations entails, enabling them to improve their collaboration with their co-workers in IT operations.
