Quotes, emphasis mine:
|
||||
|
||||
The Fediversity Project is a comprehensive effort to bring easy-to-use, ***hosted cloud services*** that have service portability and personal freedom at their core to everyone.
|
||||
|
||||
|
||||
The Fediversity Project enables easy hosting for a wide variety of fediverse platforms, all based on ***NixOS***.
|
||||
|
||||
helps with decentralisation of the internet, a core principle of the NGI, by making it easier for people to participate in the Open Social Web ***on their own terms***.

- NixOps 1 is a tool to deploy NixOS systems

calling the evaluator twice is not good enough

# Why
|

|
||||
<!-- Also _has_ problems
|
||||
|
||||
Testing and CI are underdeveloped
|
||||
|
||||
Python is probably a fine language, but it did turn away contributors, and the way the code base was set up made it hard
|
||||
|
||||
Calling the evaluator twice is both too often and too little, leading to bad workarounds.
