Comment The Media Harbour is special in that way. (Score 1) 84
The Duesseldorf Media Harbour is special in the way that the folks there didn't just chat about exotic technologies but actually used them for mission critical stuff to very significant competitive advantages. For instance: The core of Trivagos money making machine is a sophisticated use-case of an event-sourcing Kafka setup. The Invision Callcenter Software folks right next door build their products in Elixir, an exotic modern PL with a hard emphasis on concurrency running on Erlang foundations.
Regular meetups at Sipgate just around the corner covered super clean and stable real-world n-dimensional scalability of real-time systems, the type of which you'd expect from a pioneer VOIP provider built entirely on FOSS, agile principles and running with less than 200 employees but will never see in any generic German KMU (small to medium sized business) because they simply wouldn't get it. They don't just talk big words with zero substance on agility, but actually practice it. Likewise a Dart & Flutter Application crew at Vodaphone headquarters or a small but competent crew from Solingen doing full-scale billing at Peek & Cloppenburg with a custom Scala application.
Botton line: 90%+ of people at those meetups and giving talks and presentations we're completely beyond the usual mediocre bloated and badly managed C#/Java stuff. The exemplary efficiency of the folks I met throughout the years was staggering and a real regular breath of fresh air starkly contrasting the garbage I had to regularly deal with when salvaging yet another shoddy setup cobbled together by some agency and a few badly paid WP plugin jockeys. I'd argue the quality density in that small area is even higher than SV average with considerable network and attraction effects.
