I have also been switching to uv recently, frequently with --script, and I love it. What I havn't yet figured out though is how to integratge it with VScode's debugger to run the script with F5. It seems to insists on running what it thinks is the right python, not respecting the shebang.
Yes, it can also be split 1/2 + 1/4 + 1/4, e.g. when two competing efforts are recognized, one of which was two people. The rule that at most three people can share the pize can make this awkward.
The site does not seem to say who made it, but it sure reminds me of Shane Parrish (Farnam Street blog) who wrote a book about about mental models, among other tings.
For Debian/jessie it worked nicely for me to just install python3-ply and python3-pip with apt-get and then just do "pip3 install xonsh". Python3 seems to coexist just fine beside the default 2.7.
It was a temporary thing during the "year of astronomy"; the mat was on the shopping street just outside the old Celsius observatory. For the time being there is no Saturn as far as I know. But its moon Titan should still be hanging at the same spot, a ~40cm semi-translucent sphere to represent the thick atmosphere.
