Gotta love Python. Debian too:
$ apt install python-pip
Package python-pip is not available… the following replace it:
python3-pip
$ apt install python3-pip
python3-pip : Depends: python3-setuptools but not installable
Depends: python3-wheel but …
Recommends: python3-dev but …
$ sudo dpkg -i python3-venv_3.11.2-1 b1_arm64.deb
python3-venv depends on python3.11-venv however:
Package python3.11-venv is not installed.
In #Bookworm nobody can hear you scream.

This https://arxiv.org/abs/2310.01510 has been replaced.

Neutrinos from muon-rich ultra high energy electromagnetic cascades: The MUNHECA code
An ultra high energy electromagnetic cascade, a purely leptonic process and initiated by either photons or $e^\pm$, can be a source of high energy neutrinos. We present a public python3 code, MUNHECA, to compute the neutrino spectrum by taking into account various QED processes, with the cascade developing either along the propagation in the cosmic microwave background in the high-redshift universe or in a predefined photon background surrounding the astrophysical source. The user can adjust va…

Had an issue with #NixOS where I couldn't run a #Python tool that uses pandas. (Nix really doesn't work well with Python.)
Somebody helped me to find the solution by:
nix-shell -p 'python3.withPackages (ps: with ps; [ pandas numpy ])'
Today, another Python project with pandas a…

Leaned a handy #Python trick today. Needed a quick web server to test a web site. Browse to folder in Linux Mint, right click for 'terminal here' then:
python3 -m http.server 8000
Starts a web server with current directory as document root on port 8000.

Homebrew's python3 is not signed, so desktop-notifier won't work. But I can't install PyICU with the system python3. Fuck me with a rusted chainsaw #python #programming
