For a decade Paolo and I built @nextflowio. Today we’re launching Nextflow Frontier, a closed-loop discovery system for the unsolved problems in life sciences.
We spent ten years making experiments reproducible. Now we are making them abundant.

New side project! I decided to pull all of my favourite features for code blocks together into a single plugin for #Astro #Starlight. Things got a bit out of hand and it now has 26 different features.
Hope it's helpful for folks! 🌟

It's been a little while, but the #Nextflow #Podcast is back! Check out episode 58 to hear all about writing and publishing #plugins.
We covered plugins way back in ep 38, but so much has changed since then that we felt like the topic deserved a re-run!
🎙️ New Nextflow Podcast Episode: Writing Nextflow Plugins in 2026!
This one is all about Nextflow Plugins. @tallphil is joined by Jon Manning, Rike Hanssen, and Ben Sherman to discuss the world of extending core Nextflow functionality.

Last chance to register for the #NextflowSummit in-person training and @nf_core #hackathon!
We've had a bunch of new projects come in for the hackathon the past few days, I'm getting really excited for it. Can't wait to see some faces old and new, and see what we can build 🚀
⏰ Last call: Registration for Nextflow Training or the @nf_core Hackathon in Barcelona closes tomorrow.🇪🇸 Plus, connect with the Nextflow creators (@SeqeraLabs) at the Rooftop Social!🌆Spots are limited. Register by end of day tomorrow: hubs.la/Q04y5Wrq0
The nf-core #hackathon is drawing rapidly closer! Sign up now to come and join the fun 🤩
Feel free to fire me a message on Slack if you have any questions. Check out the nf-core YouTube channel to see presentations from previous hackathons to get a flavour for how it works 😀
The countdown is on for the @nf_core Hackathon in Barcelona!🇪🇸 Check out the current hackathon projects lined up for the event! Register now to get involved: hubs.la/Q04wj5g30

We're delighted to have contributed case studies to @OpenAI's report on scientific computing in the age of agentic AI. Alongside @altos_labs, we discuss agent-assisted rewrites of RNA-seq QC tools, built for @nextflowio and @nf_core.
Coding agents are helping scientists spend more time advancing research, taking on everything from routine maintenance and targeted optimization to complete redesigns and new systems.
While agents can reliably execute on ambitious projects, researchers must still define the scientific questions, verify results, and take a stance on long-term ownership.
It was fun being invited to contribute a case study to this @OpenAI preprint + blog 😊
I think it ended up a really nice overview, an interesting cross-section of how multiple people are approaching similar problems...💡

Only ONE WEEK left to submit your talk abstract for the online #NextflowSummit in October! 📅🔥
Get those abstracts in quick! 😅
🎤 The #NextflowSummit returns on Oct 13-14, and we're looking for speakers to share their experience using #Nextflow for scalable, reproducible analysis.🌎 Submit your talk abstract by July 24 to share your work with global community. 🔗 hubs.la/Q04pMXB30
I'm very happy to say that we now have new tools for @nextflowio log files in the #CLI and #VSCode extension!
Try it out with the latest Nextflow edge release (26.05.0-edge) after a run:
$ nextflow logfile
Or open a log in VSCode with the Nextflow extension installed ✨🌈
Nextflow log files are great for debugging, but digging through 1000s of debug lines to find an error can be difficult.🧵 That's why we've introduced native log viewers in the Nextflow CLI and VS Code extension.

New in @seqera.io #Containers: you can now edit the #conda environment.yaml directly to control how your container is built. 📦 📄 ✍️
The UI also shows how to do the same with the Wave CLI in your terminal ✨
Short demo: youtu.be/DkRgor8Mx4A
There are a few use cases for this, but the example shows a common one: a MultiQC release had a Bioconda bug fix under the same version number, so the normal request returned the cached image.
Editing the YAML lets you pin the exact build you want, generating a fresh image.. ✨
Check out seqera.io/containers for the tool and let us know what you think!
Registration is now open for the October #NextflowSummit! Both online virtual attendance (free) and in-person hackathon / training, in Barcelona 🇪🇸
Come and join to get new skills, meet old friends and hear the latest and greatest in scientific developments! ✨ 🎉
🇪🇸 This October, join us in Barcelona for #Nextflow Training or the @nf_core Hackathon to sharpen your skills and collaborate with the community. Registration is now open ⬇️

Join @tallphil (Senior Product Manager, OSS) and Ben Sherman (Senior Software Engineer) on June 17 to discover everything that's new in the latest @nextflowio release.⬇️
Nextflow 26.04 introduces new capabilities to help you write bug-free pipeline code and catch errors early. Join us for a live walkthrough of everything that's new. hubs.la/Q04j0cQG0
I finally gave in and wrote myself an
@elgato #StreamDeck to do "fake typing" for demo videos.
You can "type" preset texts (long-press for alt., also cycle or print random) and make it look more Human with delays, randomness and even typos 😅
👉🏻 github.com/ewels/type-deck
Had a lot of fun hacking with this over the past few days (it went through multiple variations!)
Thanks to @vldsavelyev for doing the initial refactoring work under the hood in #MultiQC and wiring up Pydantic, and starting the first version of config wizard 🎉
