Ad transcript:

Adopting an unfamiliar technology such as Nix usually comes at a cost. Productivity takes a hit, some of the team find themselves preoccupied providing Nix support, anti-patterns emerge increasing technical debt and morale is affected.

Founded by my friend and mentor Jacek Galowicz, Nixcademy have brought hundreds of individuals up to speed with Nix.

Prevent technical debt, liberate your Nix experts and get on top of Nix and back to work early. Visit nixcademy.com.

Jacek tells me that most Nixcademy clients returned their investment in training in under three months.

They also provide free educational content that I recommend and a Nix newsletter that I subscribe to.
