Experiencing team flow by Michel Grootjans

You will experience the effects of team flow in this non-technical workshop.

We will be running a few interactive simulations on team organisation and the effect this has on the total flow of work.

Topics we will certainly address:

  • Why would we prefer T-shaped team members?
  • How can swarming help?
  • Why would you deliberately limit work in progress?
  • Why is it that we have trouble estimating when work will be done?

Bring your mobile phone if you want to participate. You will only use your browser.

Speaker: Michel Grootjans has been programming since the age of 12. He has programmed strange machines like the TI 99-4A, the Atari 2600, Mac128, HP28, Apple II, Siemens PLC's, using languages like Basic, Pascal, C, HyperTalk, Assembler, ... along the way.

His professional experiences include building enterprise applications for retail, media, government, chemical plants, telecom, HR, insurance, ... in javascript, C#, java and, ruby.

He helps teams with continuous improvement, focusing on outcomes over output.

You shall not password by Mark Van Der Linden & Lucien Immink

In these modern times of real privacy protection and increased server-side security, a key risk can still be defined as “relying on a single word or phrase to protect all of one’s data”. Consider a password a secret you happily seem to share with the World Wide Web. Ponder the thought: if you start sharing your secret, can it still be considered a secret?

During this session, iO experts Mark and Lucien take you through a multitude of security measures that don’t rely on the use of passwords. They’ll share the reasons why we should move away from passwords and how you can easily implement Web Authentication to provide your users with a simple and more secure way of authentication.

Welcome, to the age of passwordless authentication!

In short:FIDO: let’s solve the world’s password problem, togetherWeb Authentication: there once was… a credential management APIAuthenticators: ‘And who might you be?’


As a developer, I always want to know how something works in detail. This usually means a hands-on approach, delving into the technical details and finding the limits. However, sharing the findings and making my colleagues and friends just as excited, is what really makes me enjoy technology and with that, my job.

As a Software Architect, I do just that, making sure the technologies are known by the team and supports the customer’s needs. Authentication is something we all deal with every day, developers, and users alike. It's however rarely looked at as a fun thing to delve into. I took it on myself to figure out a way to make it more fun and less frustrating to deal with authentication on the web apps we visit and develop every day.


Lucien was once a Java developer through and through until he saw the light and embraced Internet Explorer 6 as his digital overlord. Today, Lucien is a Google Developer Expert with over 20 years of experience and is done with reinventing the wheel to fit the shiny front-end framework of the day. As you’d expect from a developer advocate, he prefers finding proper, simple and elegant solutions designed to help out others.
