I hadn't updated my development environment in a while, and my package manager (to download and ensure every module has the right dependent modules, if you aren't familiar with Python), Conda, was taking for ev errrrrr!! I had read about a newer manager, uv, written in Rust (the compiled language all the cool kids are talking about), so I figured it was time to try it.

Night and day. I downloaded and configured my entire development environment in about 30 seconds. It uses `pip` commands, though those are rewritten, too. I just gave it a file with a list of mandatory modules and it put in the latest versions, though I could also specify which ones I needed. Super simple.

(I'm trying putting the tags at the beginning of the post to make it easier for people who wouldn't be interested to scroll past. Let me know if this makes it worse for you.)

Software provenance with #Snakemake: Using the reporter plugin for nanopublications, we can now get slightly improved nanopublications like this one: https://w3id.org/np/RAmgzfta63xx0wWc_zzQVm7kwOc4tsEOA0JJJCfsiLL1g (press on the little blue arrow on the right to see the full details). Automatically captured for this workflow: https://w3id.org/np/RAjHDlPDghZzc9ZvQ3uJQNJ9Jd_KAYzZt7dk5PXKgjRyE - again expressed a nanopub declaration. 😉

It now supports to capture the "classic" software support for #Conda and Snakemake wrappers.

There is more work to do. Let's see when and if I get to it.

@millihertz what #Python really needs is a way to distribute pre-build #conda environments without using flatpak or docker or the like. Yes, you can send an env file and make people download everything themselves, but I'm thinking pre-packaged "this is all the stuff in my environment for this package" as a ZIP type blob that acts as conda environment to the app.
ymmv.

#gnuradio

On #macos #tahoe installed with #conda, I'm going slightly insane.

gnuradio (v3.10.12.0) depends on qt-main (v5.15.15)

gnuradio also depends on qwt (v6.3.0) which depends on qt6-main (v6.10.1)

So, now I have both qt5 and qt6 installed .. by the installer .. that fails when you attempt to run anything because there's two versions of qt installed.

Anyone?

I finished the basic #tutorial for #snakemake and it really fits my vibe right now, hehe
Also learned a bit more about #conda along the way. I'll take that

Last week I was a little annoyed about missing Microsoft C++ Build Tools #MSVC on a system without admin rights. I needed a compiler for building the #python C++ extension I developed a while ago. Annoyed not because I could not ask someone to install it for me, but annoyed because of the lack of compiler choices in this particular case. I have to use the MSVC instead of let's say #g++ which I could easily install via the #MinGW-w64 #conda package myself.

I found out that I can tell #setuptools (the backend build system) via #pip config settings to use a different compiler during build:

Join Michigan Python December 11th (Thursday, 7pm ET) for my talk on Building Your First conda-forge Recipe!
We'll build a GTK code editor, discover GtkSourceView isn't on conda-forge, and package it ourselves. Learn to create recipes, build native dependencies, and contribute to conda-forge.

I am really enjoying the Pixi package manager, https://pixi.sh , made by @prefix. We have been using conda at my work for managing the dependencies of our python application. It involves scientific data analysis so there are lots of dependencies, and it has been a challenge to keep things up to date. Pixi has nice support for cleanly defining the direct dependencies in the pixi.toml file, and then it automatically generates a lock file. There is a command to upgrade all the dependencies too. It's amazing! I'm just starting to use it, but it is helpful so far.

Last week I was in Málaga with the @conda OSS team (Anaconda + Quansight).

Aligned on vision and roadmap. Had real talk about code review anxiety and supporting each other better as a distributed team.

Sprint day highlight: shipped progress on wheels support and sharded repodata. Nothing beats building together in person.

Excited for 2026 🚀
