I started CphEx back in October 2014. I created a Twitter account (https://twitter.com/cph_ex) and a GitHub organisation (https://github.com/cphex/), made some initial noise on the internet about it, planned a formal meet up at a café, and went there not knowing if anyone else would show up. Luckly some did, and since then we have had a meet up every month. We have grown the community and we are now around eight people partaking in the monthly meet ups and our events are now hosted at venues kindly offered by companies located in greater Copenhagen, with projectors and sometimes snacks.

We have had some discussions whether or not we should be on a meet up site of some sort, meetup.com, lanyrd.com, Facebook groups, etc., but personally I have spoken against it for the following reason: They are not inclusive as they force a notion of a structure, and they rise the barrier of participation without giving much back.

My initial strategy with the Github repo was: If you are interested in Elixir and you want to o

Important KoldskålsConf 2015 Announcement

TLDR; due to my fault the excitement about the KoldskålsConf did not last long, and as one of the initiators I really do not know where we stand with this thing; so I guess it is better to cancel it.

Hi, I am Martin, and I am the guy who started the talk about doing a conference about a Danish dessert called Koldskål and weird tech; KoldskålsConf—a Danish/Copenhagen pendant to the legendary bay area conference called TacoConf.

But mistakes were made and they were made by me.

The concept had a ton of excitement in the beginning, but I did not manage to keep that excitement going. Excitement about a thing like this is important, because it was supposed to be organized in a way where everyone who wanted to help out could help out, and make it an actual thing.
