Quick report on Malmö coders’ book club: This was the initial sitting, and we were 7 people around the table. One academic, two leads, and four software engineers. We spoke English, since we were an international crowd. At least three physical notebooks full of written notes were out, and the conversation was started based on …

Travel report: MirageOS hack retreat in Marrakesh 2017
I am just back from a week off in Marrakesh. Together with a hearty group of people from many places, I wrote and documented software in the heart of the medina.

Cinemateket: a personal failure to build habit
The new slimmer Cinemateket. It never really came together, my going there out of habit. Habit-forming failure, if you will. Now that they’ve scaled it all back to a trickle of must-see films from the nowadays-much-smaller showable-as-analog past, it’s lost much of its previous smorgasbord charm for me. Choosing not to view a certain film …

Export data from MongoDB 3.0 and import it into MongoDB 2.6
I just had the dream meeting with a dockerized app. This is a use-case for containerization. I had to use MongoDB 3.0 to export some data and place it in a 2.6. Ouch: The 2.6 can’t connect to the 3.0. I didn't even know that mongodb still existed. — Martin Gausby (@gausby) November 29, 2016 A …

Game prep
See, this list of game preparation is soon a year old: Buy skulls as game chits. Invite players and nag them to confirm attendance. Read the text of the scenario to play. Try out the conflict system. Practice run. Realize the rules are many but smart. List game activities. Figure out snacks and food.
Hold Elasticsearch back on 2.4 for Chewy on macOS
So, Elasticsearch 5.0.0 is out. I’m using Chewy, a Ruby DSL gem that’s quite good. It’s not quite there yet with the deprecated Query APIs, (see Release Notes), so to keep using it you need to hold back to the Elasticsearch 2.4 series which is the last stable release. (Question about this, answered in the issue …

Around town in May
Peter visited Malmö, and we sat down to decompress at Simpan. A fancy poster for a reading of a book by Swedish genius author Birgitta Stenberg.
Architecture Decision Records
adr-tools is a set of command-line tools by Nat Pryce that allows people in software projects to record their design decisions, as they go along, a bit like the captain’s log on the Enterprise.
