Scheme, not typed language (kind of rare at CUFP)

Guix

Free software movement
Deploy software using purely functional paradigm
GuixSD - Guix System Distribution
- guix package -i guile
- guix package -r guile -i python
- guix package --list-installed
Environment Variables suggested on install
Stores generations
- Packages and install histories are managed and can be viewed / restored
- guix package --list-generations
- guix package --roll-back
Scheme configuration file
- Don't really need to know scheme to use though
- guix system build schememachine.scm
Can run configurations in servers / vms
Deployments etc.

Why?

Is there a package manager for neural networks?
Lots of language-specific package managers
Almost every programming language have their own package managers
This is good for development, but difficult for system management
Language-specific PMs often assume things that aren't necessarily true about your environment
You want states of machines to be the same across distributions

Functional Package Management

build process is a pure function
Software built with this function is an immutable value in a graph of packages
Builds are stored in hash of all dependencies

Scheme All The Way Down

Configurations scheme all the way
Package manager all scheme
Scheme determines packages and how they build and their dependencies and how they build
Scheme all the wawy up to OS declaration level

Summary

Distro and tools as scheme libraries
Hackable through uniformity
Using code staging capabilities to glue it all together
