My favorite questions for the first 1-on-1
Last year we split our IT team into three smaller teams. One reason why we split the team is that the team just became too big for one manager. I took over one team and then was team lead of three developers. So, managing them was on my plate and one of the things I was really exited about were 1-on-1s with my team.

Vaamo Dev Team Meeting - Cognitive Biases & Expectations around communicating
Every other week the complete vaamo development team gathers and talks. Sometimes we talk about general things like workflow optimizations, other times we do agile-style retrospectives, then again we talk about what comes to our mind. Whatever it is, it must be about how we as a team can improve in our work.
In this post I share the meeting's summary, which I sent to the team, with you. -

JavaScript Journey Chapter 3 - Fundamentals continued with function scope

There is always a little adrenaline surge when I see one of my commits failing on Travis, which we use to continuously integrate our projects.
