Did you know that all @nextflow.io #training videos (and podcasts!) have their subtitles manually curated? They're really high quality - even for technical terms.
Great if English is not your first language, or if you can't understand my accent! 😆

The CLI is handy if you're already in a terminal - run `quiz`, pick from available quizzes in your repo, and test your knowledge without switching to a browser.
It uses rich for beautiful markdown rendering with syntax highlighting 🌈, plus has a `history` command to track your scores.

Running with data on AWS s3? Update to the latest version of @nextflow.io (25.10) and get some pretty tasty performance improvements for free 🤩
These kind of "under the hood" improvements can often go unnoticed, but it's this work that makes #Nextflow capable of powering huge analysis workflows 💪🏻

Really excited to announce the v1.9 release of the `rich-click` library 🎉 It's a Python library that uses builds on top of command-line help output from click, giving you beautiful output with only a couple of lines of code 🪄 ✨ 🌈

Here's a little easter egg for those of you using @seqera.io #platform.. 🥚 ✨
Recently we released a new feature that lets you set custom pipeline icons. What's less well known is that animated icons are also supported - party time!! 🪩 🥳 🎉
The trick is to rename your .gif to a .png file extension 🤫

Last year I gave a talk at #PyCon Sweden about one of my pet-projects: rich-click.
The title was "Accidentally popular: Beautiful CLI interfaces with rich-click". I talked about the library, but also the #opensource journey, involving @willmcgugan.bsky.social, @tiangolo.com and Daniel Reeves 😊

That feeling when AI can create cat videos with better @nextflow.io training content than you've made in years.. 😻 😹
Could this be the new face of #Nextflow at @seqera.io ?!

This is something I'm *super* excited about - @seqera.io studios isn't just Notebooks / RStudio / VSCode any more: You can now take basically *any* graphical application you can think of, chuck it into a Docker image and run it interactively in Studios.
The possibilities are endless..

I know I've posted quite a lot the past few days (sorry), but this is super cool. Check the PDF for some really nice plots showing how Fusion works and *why* it's able to give cost savings over base AWS fees (no signup for the PDF required).

I'm super excited to be going to Vienna in June for @esaearth.esa.int #LPS25 - it doesn't get much better than giving a talk at a European Space Agency conference!✨🛰🌍
I'm hoping to bring @nextflow.io to more people working in the earth observation field, we have a lot in common..
