Hi,

Dogelog Player is a Prolog system for JavaScript,
Python and Java targets. It has still some macOS
genes, since couple of years ago our development
environment featured a Mac Book. We recently did
a cross testing exercise for Dogelog Player on
a brand new Mac Neo.

In our Zoo of AI laptops we had to rank the Mac
Neo third. Still the Mac Neo, a beautifully silent
and affordable product, excells for example in
JavaScript and clearly leaves behind the other
Think ARM machine, since we couldn’t find a PyPy
Windows ARM build.
