One week on from @nextflow.io Training & @nf-co.re Hackathon at #NextflowSummit Barcelona. 🌍 What stood out: the real-world impact this community creates together. 🙏 Thanks to participants, trainers, project leads, mentors, Ambassadors & the nf-core core team. See you next time!

🎥 All the talks from the #NextflowSummit are now available to watch on-demand. Catch up on sessions from 50+ speakers, including Roche, @boehringerglobal.bsky.social, Myriad Genetics, @nasaupdates.bsky.social, Benchling, Lonza, @nf-co.re, @seqera.io, and more! ▶️ Watch now: hubs.la/Q04C2jnc0

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! ewels.github.io/starlight-co...

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!

Last chance to register for the #NextflowSummit in-person training and @nf-co.re #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 together 🚀

Nice! Just got accepted to give a talk at PyCon Sweden #PyConSE2026 🐍 🇸🇪 about *Starlight-Pydocs* I gave a talk there in 2024 and it was great fun. Looking forward to it already 😊 ewels.github.io/starlight-py...

Just 1 month to go until Nextflow Training and @nf-co.re Hackathon in Barcelona!🧦 Here's a sneak peak at exclusive swag you'll receive: stickers, t'shirts, socks and more! Register by Sep 24 to join the fun: hubs.la/Q04xwzJB0 #NextflowSummit

Curious about the nf-core Hackathon in Barcelona this October?👩‍💻 Check out hackathon projects and group leaders so far🧵

Learned today about @stephenturner.us's "/deslop" skill. Very useful! blog.stephenturner.us/p/deslop h/t @ewels.bsky.social

I spent most of my time at the 2024 #Nextflow @nf-co.re hackathon working on genomeqc. Happy to see our preprint finally published: nf-core/genomeqc: a best-practice pipeline for comparing genome and assembly quality: www.biorxiv.org/content/10.6... 🧬💻🧪 github.com/nf-core/geno...

We're delighted to have contributed case studies to OpenAI's report on scientific computing in the age of agentic AI. 📃 hubs.la/Q04r75Zm0 Alongside Felix Krueger (Altos), we contributed agent-assisted rewrites of RNA-seq QC tools (RustQC, FastQC-Rust & more), built for @nextflow.io and @nf-co.re.

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 people are approaching similar problems with #ai #agent -assisted #bioinformatics software projects...💡 openai.com/index/scient...

Welcome to the Program!🎉 We're absolutely delighted to be welcoming 43 new Nextflow Ambassadors to the Program who will help foster collaboration, organize events, and support fellow community members across the global Nextflow ecosystem.🌎

📢 Deadline tomorrow: Speak at the #NextflowSummit by @seqera.io this Oct.🎤 We want to hear how you're using Nextflow to solve real bioinformatics challenges at scale, from pipeline development to agentic approaches and more. Submit your abstract now: hubs.la/Q04qsyFn0

Only ONE WEEK left to submit your talk abstract for the online #NextflowSummit in October! 📅🔥 Get those abstracts in quick! 😅

New @nf-co.re monthly #newsletter is live! Read all about it in a new blog post out today: nf-co.re/blog/2026/ne... You can get monthly emails, or subscribe on LinkedIn: www.linkedin.com/newsletters/... Little promo clip made using hyperframes.heygen.com just for fun 😅

Happening right now: join @ewels.bsky.social in a @nf-co.re #bytesize talk to hear all about our newest feature: monthly Newsletters! nf-co.re/events/2026/...

I'm very happy to say that we now have new tools for viewing @nextflow.io log files for both the #CLI and the #VSCode extension! Try it out with the latest Nextflow edge release (26.05.0-edge) after a run: $ nextflow logfile Or open any log file in VSCode with the Nextflow extension installed ✨🌈

Registration is now open for the October #NextflowSummit! Both online virtual attendance (free) and in-person hackathon / training, in Barcelona 🇪🇸 Come and join to see what the fuss is about, get new skills, meet old friends and hear the latest and greatest in scientific developments! ✨ 🎉

It's amazing to see how much Nextflow has grown! When I joined Seqera in 2022, there were multiple places around the world who barely had anyone who had ever run Nextflow. It's a totally different scenario in 2026, and it's so nice to have been on board during this trip! 🤩

Jeremy Wang developed rammap, a minimap2 rewrite in Rust. It achieves comparable or better performance than minimap2 and produces identical output to minimap2. During rewrite, Jeremy found two long-existing bugs in minimap2 which are fixed in v2.31. www.biorxiv.org/content/10.6...

Join @ewels.bsky.social (Senior Product Manager, OSS) and Ben Sherman (Senior Software Engineer) on June 17 to discover everything that's new in the latest @nextflow.io release. ⬇️

@multiqc.info has ~200 config options for customizing reports: renaming samples, reordering modules, dropping stats columns, tweaking plot defaults, and more.📊 But most users don't know what's possible, so we built a MultiQC Config Wizard. hubs.la/Q04hgKlS0

I finally gave in and wrote myself an @elgato.com #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 😅 Code is on GitHub 👉🏻 github.com/ewels/type-d...

Had a lot of fun hacking with this over the past few days (it went through multiple variations!) Thanks to @vladsavelyev.bsky.social for doing the initial refactoring work under the hood in #MultiQC and wiring up Pydantic, and starting the first version of config wizard 🎉

Producing the rewrite is only the start of the story though. @ewels.bsky.social joined @robert.bio on the OMGenomics podcast to talk about rewriting bioinformatics tools in Rust and what AI-assisted development looks like in practice. 🎧 Give it a listen: hubs.ly/Q04gY5Kq0

It was great fun talking to @robert.bio and his edit is great (I love some of the overlays, especially the one about @robp.bsky.social being an authority 😂)

All the videos from the Boston #NextflowSummit are now available on YouTube! There are some brilliant talks in there 🤩

Nextflow 26.04 is here!🚀 This release makes writing bug-free pipeline code easier than ever, whether you're coding yourself or working with AI agents. Clearer errors, stronger types, and simpler code reuse. hubs.la/Q04d-6m60

@ewels.bsky.social from @seqera.io just dropped a mass of knowledge about RustQC, a single Rust binary replacing 15 RNA-seq QC tools with 60x faster speed, built entirely with AI and zero prior experience. Plus, rewrites.bio for responsible rewrite principles🤯 #NextflowSummit

Yessss new socks for the collection! 🧦

Did you miss the registration deadline for the Boston #NextflowSummit? Fear not - all talks will be live streamed online! 🎉 The hybrid event will use the same platform as the October 2025 event, you can watch live and ask questions for the speaker. Hit the link below to register!

Heng Li's blog posts are always thoughtful and well written, this is no exception. Great to see folks coming to similar conclusions around #Rust #rewrites in bioinformatics. Also appreciate the RustQC / rewrites.bio cite 🙏🏻

The nf-core Hackathon in Boston is happening in just over 2 weeks! 💻Join us April 28–29 for two days of collaborative hacking.🎟️ Register now: hubs.la/Q04brb4c0 Whether you want to add new features to existing pipelines, work on tooling, or tackle community initiatives — there's something for you.

Very very important initiative, check it out #bioinformaticians!

AI coding assistants just passed a threshold: domain experts can now rewrite established scientific software in days. This wave of rewrites is coming for #bioinformatics. The question isn't whether to embrace this capability, but how to do it responsibly.🧵 hubs.la/Q04b85ww0
