ParseJSON typeclass should probably be FromJSON?

Sounds about right, except the last statement. You need types:)

If you read the script, you'd realize this is not true.

You have a choice to use automated script or copy each imperative step on your own. All the freedom you can possibly get.

That falls into the use case where nixos.org gets compromised, which is a hard problem to solve in the first place.

People can either read ebuild or bash script, it's the same thing. Only ebuilds have more abstraction.

As for the tarball, Nix only populates /nix, so it doesn't touch your filesystem structure at all.

That's exactly what we don't want to do, maintain installation scripts for hundreds of different ecosystems besides our own.

For this reason I've been using structlog.readthedocs.org

Re: GZipped JSON files and Logstash

This would be extremely useful to have upstream in logstash. UDP has a max data length limit and compressing messages when hitting that limit would help remove the constraint.

It's possible to only allow a subset of unfree packages via `allowUnfreePredicate`. It's not documented yet though.

FYI: Nix uses chroot while building packages (not by default though, but our build farm enables that)

Agreed - updated the blog, thanks!

There is *nix-env -q*, or do you mean online? Also, packages are for Nix, NixOS has modules.

Re: Build Tools - Make, no more

Domen Kožar — Mon, 21 Apr 2014 12:00:54 -0000

Bingo. This is why I believe in order to solve that problem, we need a portable package manager that aims for reproducible builds. Wrap any build system people invent with a function and provide docs how to use it.

Nix (http://nixos.org/nix/) does a very good job and we even have a whole distribution built on top of that (called NixOS).

The solution (sadly) isn't to force people to reinvent package managers for their language, because it kind of does make sense to do it. The problem arises when they try to package more than just packages from their language and based on ad-hoc solution there comes the need of packaging X language with a little bit of C and maybe some scala.

Fixed, thanks.

When NixOS starts solving your problems, those hashes soon become part of routine

That's what I'm saying. Output of ldd $(which nginx) on NixOS: http://bpaste.net/show/187748/

Omnibus: quick look reveals it's definitely going the right path. But prefixing is only one of the steps you have to take to do stateless configuration management. The missing puzzle is eliminating all other things and depending only on packaging instructions. That's the part that's hard to fix in current packaging managers.

Could you point out inaccuracies? I'd love to fix them. I agree it's a bit provoking, I couldn't think of a better way to explain the motivation. References paper does take a different path (again I encourage you to do afternoon reading, together with Nix PhD thesis http://nixos.org/~eelco/pub...

Note: these not my ideas and you can use them today http://nixos.org/nix http://nixos.org/nixos

Many NixOS users do use btrfs/zfs, indeed.

Docker doesn't solve any of the problems with packaging we have nowadays. Yes, freezing state of the system helps a lot and it has it's use cases. But it's not a general solution to the problem, that's all.

Re: Why Puppet/Chef/Ansible aren't good enough (and we can do better)

Domen Kožar — Tue, 11 Mar 2014 10:45:10 -0000

CoreOS is something I still have to look into. It's definitely another approach to solve a set of the problems, I'm sure it would be interesting to see what it does better.

Re: Why Puppet/Chef/Ansible aren't good enough (and we can do better)

Domen Kožar — Tue, 11 Mar 2014 10:41:39 -0000

Yes. "nix-collect-garbage -d" will get rid of your history.

There is also "nix-store --optimise": The operation --optimise reduces Nix store disk space usage by finding identical files in the store and hard-linking them to each other. It typically reduces the size of the store by something like 25-35%.

To install NixOS, you need to use live cd. Do you get any erorrs? You're welcome to stop by on #nixos at freenode, I'm sure we'll find a way!

Sure, you'll get 64bit Nix binary installed on your Ubuntu machine.

If you want to install NixOS, here are the instructions: http://static.domenkozar.co...
