love uv, quickly generate a bcrypt password on the command line

uv run --with bcrypt python -c "import bcrypt; print(bcrypt.hashpw(b'your_password_here', bcrypt.gensalt()).decode('utf-8'))"

Wrote a little piece about using UV on Fedora Linux, for handling many tasks like installing common tools to managing your own projects dependencies.

Sharing single-file Python scripts with external dependencies is now easy thanks to uv and PEP 723, which enable embedding dependency metadata directly within scripts. This approach eliminates the need for complex setup tools like requirements.txt or package managers, making script distribution and execution seamless and simplifying deployment while maintaining flexibility and efficiency.

I'm in love with uv. Seriously, the tool is small yet packs a punch with features.

I'm writing an article for Fedora Magazine about the cool things you can do with uv, here is the source code (with the article in markdown) for your enjoyment:

Exploring UV: self-contained Python scripts made easy
https://hleb.dev/post/exploring-uv/

Saw this very nice article on slack about making standalone #python scripts that use #uv to automatically create their own virtual environments and install their dependencies there.

Single file #python scripts with inline dependency meta data - #uv ftw

Porównajmy backendy #PEP517 dla paczek napisanych w samym Pythonie:

#flit-core: 51 KiB archiwum źródłowe, bez zależności, instaluje się 0,05 s, ~150 KiB po zainstalowaniu, działa wszedzie
#UvBuild: 300 KiB archiwum, wymaga ~250 zależności crate (54 MiB pobierania, ~600 MiB w .cargo), buduje się 1 min 20 s (na 12-wątkowym procesorze), 4,2 MiB po zainstalowaniu, wspiera kilkanaście platform

I oczywiście, że flit-core ma szerszą funkcjonalność. Ale jestem przekonany, że gdzieś ktoś potrzebuje zaoszczędzić te kilka milisekund budowania paczek Pythona.

Let's compare #PEP517 backends for pure #Python packages:

#flit-core: 51 KiB sdist, no dependencies, 0.05 s to install, ~150 KiB after installing, works everywhere
#UvBuild: 300 KiB sdist, requires ~250 crates (54 MiB download, ~600 MiB .cargo directory), 1 min 20 s to install (on a 12-thread system), 4.2 MiB after installing, supports a dozen platforms

And yes, you guessed right, flit-core has more functionality. But I'm sure that there are performance-critical wheel building workflows that will benefit from these few milliseconds shaved off wheel building time.

un article du blog "bite code" (que je vous recommande de suivre ou de fouiller - plein de choses intéressantes sur les #tests aussi, par exemple) sur un retour d'expérience sur https://github.com/astral-sh/uv, le gestionnaire de projet #Python de @charliermarsh, après un an d'utilisation de #uv dans différents contextes : https://www.bitecode.dev/p/a-year-of-uv-pros-cons-and-should

A year of #uv: pros, cons, and should you migrate #python

https://www.bitecode.dev/p/a-year-of-uv-pros-cons-and-should

I like #uv just like the next door #Python user, but I'm very frustrated that when I create a venv with it the standalone interpreter it installs breaks a lot of stuff based on #tkinter, a lot of stuff I depend on, like Thonny and FreeSimpleGUI :((

Great news for #python developers! #dependabot now supports #uv #astraluv . Nothing stands between your codebase and almost-instant #dependencymanagement!

We also have lightning talks! @tero is showing us how to write single-file executable Python scripts with dependencies using uv.
