Nixcademy ad transcript:

Statistically speaking, Nix is a novel technology.
As such, adoption comes at an immediate cost of productivity.
Team members who know Nix find themselves preoccupied providing support
and the emergence of anti-patterns adds technical debt.
What's worse; morale is affected.

But, with training, these costs can be all but elimitated.
Founded by my friend and mentor Jacek Galowicz,
Nixcademy have brought hundreds of team members up to speed with Nix.
It's what they do.

So, liberate your Nix experts,
prevent technical debt
and get on top of Nix and back to work better and sooner.
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 newsletter that I subscribe to.

Determinate Nix ad transcript:

You may be a huge Nixer, seeking to apply it to everything at work.
But — security, compliance, and scale.
Enter Determinate Nix.
It is the Nix that powers our systems.
But with the governance, stability, and features to back an enterprise Nixer.
Such as:

- Parallel evaluation
- Out of the box native Linux builder on macOS
- Lazy trees
- Automatic certificate handling
- First-class mobile device management

And the list goes on.
Visit determinate.systems to find out how Nixers in charge of critical infra
such as finance and defense turn deterministic fantasy into reproducible reality.
