dotfiles 2.0

Sharing my dotfiles setup

People that I work with have expressed interest in my dotfiles setup. They have seen it in action and want to use it. My dotfiles 1.0 is a combination of my own stuf and things that I've picked up from others over the years. But it contained things that I cant share (like cloud environment settings).

So I've created a 2.0 version which I can share publicly. I switched to the git bare repo method which results in a cleaner looking homedir.

Visit github.com/dsteenstra/dotfiles and have a look.

Feel free to fork and modify it to suit your own personal needs.

Interests

Apart from being an Infrastructure Consultant, I spend most of my spare time as a voluntary firefighter in my hometown. Although still in training I believe I will never stop learning. And I find it rewarding to give something back to the community.

I try to find balance between serving my business clients and doing my duties which come with this voluntary job. And I've never had any complaints.

When not playing with fire I like being less serious and love to cruise around on a motorcycle or on a boat and just have fun with friends. Life is beautiful so why not enjoy it?
