We've completely revamped ✨
Developer environments should be as simple as toggling options.
Especially if you're exploring Nix, give it a try ✨
• languages
• processes
• services
• scripts/git-hooks
• tests
• containers
• poly/mono repo support

My twitter feed:
- oh crap, Python2 is going to be legacy in 2020, 12 years after first release of Python 3, what to do?
- companies updating to GHC 8.8.1, which was released 3 weeks ago
Static typing has won, just need to open your eyes.

It's going to take another few years before developers recognize that Haskell folks have built an amazing technology built upon foundations of math. And yes, it's also easier to use for humans. Go, etc will be remembered as Java. Good ideas take time.

I've been handling commit access to nixpkgs for years and once I stopped that process only one person thanked me for it and a dozen of people full of hateful messages.
I didn't do it for anything else than to help Nix, but this culture will have to change by people stepping up

This book aims to be the comprehensive manual for type-level programming. It's about getting you from here to there---from a competent Haskell programmer to one who convinces the compiler to do their work for them.

To learn Nix, I think we have a three step journey:
- it's JSON datatypes + functions, just copy the snippets
- read the 2-3h tutorial on the language
- look up functions you need at
That's it folks.

If you're setting up any Nix machine that will be used as a builder, use a filesystem that has dynamic inode allocation.
Not ext4, but btrfs/zfs.

Not that it matters but:
- cachix/cachix took ~4 years to hit 501

So many people are wondering what's there to be done about all the drama in Nix.
Absolutely nothing needs to be done, wait for the dust to settle.
Take time to chill, go to nature, and do whatever means living meaningful for you.
Everything will be fine.

Educating about Haskell starts with the fact that one needs no background in math in order to program in Haskell. If you want to dwell on prejudice, do it, but it's going to be hard to be educated.

Looking back before learning Haskell, I remember so many people say: good luck, we'll see what you can do in a few years.
Two years later I discover the ecosystem and it's so much better than Python but so underused and underdocumented. But it's built on a solid foundation.

I'm so amazed how far we've come with nixpkgs.
It used to be a work of ~50 people to bump packages, doing a lot of monkey work.
Nowadays there are automatic PRs of package bumps on github, already built by CI and with binaries available.

I'm happy to announce we're finally restructuring the NixOS Foundation and I'm going to be a board member!
There's a lot of work to be done for the better future of the Nix project.
To ensure a balanced future for
@nixos_org
, my stance is that we should restructure NixOS Foundation to be represented by board members from active members of our community.
This is no small or simple restructuring, but it makes sure that all interests are challenged equally.

- recursive Nix (incremental builds)
- content-addressable paths (early cut-off)
And all the other things that Bazel can't do.

What you're observing on the surface of the Nix community is internal fighting.

The next step is to conquer, where we'll see gaslighting and power-grabbing.
