That’s a wrap for day one of #SocratesBE
Here’s a FOMO inducing photo of today’s marketplace.

1/ Experiments are useful to learn what's possible, to discover your blind spots, to generate optionality (aka the availability of options even when you don't need them), and to allow innovation. Without experimentation for the sake of discovery, there's no science, art, philosophy.

Couldn’t be happier with yesterday’s 1st edition of KTConf.be.
Some quick stats:
We had a total of 59 Kotlin fans attend, including 8 speakers, of which 5 international ones.
Big shout out to Kunlabora, Triple D, DPG Media, PTV Logistics and of course @jetbrains.com for their amazing support.
