What I don't understand is that python2 and python3 are still advertised as the same language. For Python's developers, this is arguably the case - basing on Python2 source code, they made some changes and just published a new ver

I think a lot of these ideas have gone into Python's Numpy, for example. But I believe these are useful for the domain of signal processing and numerical computation, and not that well suited for general problems. (You might be interes

Just a reminder, you can also use Guix as a package manager only on top of, for example, a Debian or Arch system (I am using it currently on top of both). This works very much like Python's pip / virtualenv, and is extremely helpf

I think what will make the most difference in the long term is using GNU Guile Scheme as language for package definitions. I think it is a brilliant choice to use a mature and popular language which supports functional programming very well

To mention, I think Nix or Guix are indeed good complements to things like redo! Guix System and NixOS are just geared to define the whole system, while make or redo build a single program or a set of artifacts.

Ah, and no, it does not follow from what I said, I am just reporting about redo's properties. As said, using redo is very very simple, but it is also mind-blowingly different from make. It is not difficult to understand, but the orig

You could read here: https://redo.readthedocs.io/en/latest/#whats-so-special-abou... (I think this explanation is much better than what I can do) And yes, it can build specific intermediate files or targets.

Make works pretty well, that's why it is used. But there are a few points it does not cover: - Recursive building is complicated. it is not really easy to compose a small unit into a larger project, so that one just needs to copy the s

Yeah. I am wondering since a while whether well-known algorithms like the binary heap are still efficient on modern architectures, because their random memory access patterns.
