Elizabeth Osanyinro is building PyData Bradford between Leeds and Manchester — and she's got one clear ask for NumFOCUS: A speaker bank. "When you're short of speakers, it can be really difficult having to send cold emails to potential speakers and all of that. If we had a speaker bank — oh, I need a speaker! NumFOCUS, can you get me one?" It's a simple idea with a massive potential impact for local PyData chapters everywhere — especially in smaller cities where networks are thinner, and outreach is harder. MK noted it live: first time they've heard this one. And it landed. I f you're someone who speaks on data, AI, or open source topics and wants to get connected with local communities, drop a comment.

Meet one of the panelists for the next session of the b.o.s.s. (best of open source software) town hall series! This session centers on the topic: How A.I. is showing up in O.S. communities. Travis Oliphant, CEO/Founder, OpenTeams | Creator of NumPy, SciPy, Numba | Co-founder, NumFOCUS Dr. Travis Oliphant created NumPy (2005) and launched the SciPy project (1999), foundational libraries now used by hundreds of millions of people worldwide and instrumental in making Python the backbone of modern AI. He co-founded NumFOCUS and Anaconda, and later founded Quansight and OpenTeams to support open source commercialization and enterprise AI. He remains an active advisor to AI startups and a leading voice on the future of open source communities. Join the conversation by registering online at hubs.la/Q04m4P330

Somewhere right now, a grad student is running a summer simulation that will become a published paper. A researcher is prototyping a model that will get cited in a policy document. An undergrad is writing their first open-source contribution. All of it running on tools NumFOCUS helps sustain. Innovation doesn't take a summer vacation. Neither should your support.

Dynare is pleased to announce the release of Dynare http://7.1. This maintenance release fixes various bugs. The Windows, macOS, MATLAB Online, and source packages are available for download at the Dynare website at hubs.la/Q04ltsdn0 Max the Stack to support future updates from projects like Dynare at hubs.la/Q04ltkzx0

Open source scientific computing doesn't have an off-season. Publishing papers, shipping updates, and building the tools that will power next year's breakthroughs happen year-round. Fuel the future this summer: hubs.la/Q04kYgyx0

[NumFOCUS Project Update] GRASS http://8.5.0. A Step Change for Python Users. After two years of focused work, the GRASS community has shipped http://8.5.0. The biggest story is how much better GRASS feels from Python... But you have to read the NumFOCUS project update blog to learn more about that.

Maxed-Out Moment — SciML   Scientific machine learning is one of the most exciting frontiers in computational science — and it’s happening in open source. Watch the SciML project demo from our b.o.s.s. town hall series.   Innovation thrives because of community support like yours.   Link: hubs.la/Q04knvw-0 Max the Stack by donating at hubs.la/Q04knzWT0

Open Source Software Needs You   The Sovereign Tech Agency just committed $300K to mlpack, a NumFOCUS-sponsored project, to strengthen open-source machine learning infrastructure. Their reasoning: the general lack of investment in open-source ML/AI has allowed a few dominant players to play an outsized role in shaping our digital infrastructure.   Government funders see the stakes. Do you?   Max the Stack and keep critical open tools funded, independent, and accessible. hubs.la/Q04k9x380

Thanks again to @teoliphant for taking the time to sit down with us and talk about his impact in the open source scientific computing community! @openteamsinc

Imposter syndrome is real — even for the people who built the tools everyone else uses. Travis Oliphant, creator of NumPy and co-founder of NumFOCUS, says this to anyone who feels like they don't have enough to offer: "Everybody has a unique perspective, has experiences nobody else has, has a way of thinking nobody else has. So everybody has something to offer." His advice: release early, release often. Seek mentorship. Stay open. Iterate. And above all — be brave, and be kind. From Give Me 5 Season 2.

What's Travis Oliphant — creator of NumPy and co-founder of NumFOCUS — building right now? He calls it the distributed AI economy. And he's approaching it from three angles: Open Teams — a distributed AI marketplace where people can buy, sell, and build on open source A venture fund & incubator — to support entrepreneurs building businesses that serve in that economy and deploy capital where it has the most impact The Applied AI Society — a nonprofit focused on upskilling, community building, and keeping AI and your data in your control "We're in a moment that can serve all of us, or serve a few of us. I'm really eager to see people lean into the open source ethos that led to AI as it is today." Check out our YouTube page tomorrow to see his full Give Me 5 episode.

The NumPy team was busy in April on two significant fronts. First, they’ve completed a major rework of their release process to deliver meaningful improvements for supply chain security — a critical investment for a library that underpins nearly all of scientific Python. Second, the 2025 NumPy Fellowship has concluded with an impressive outcome: NumPy is now fully type-checked. This milestone brings improved developer experience and editor tooling support for one of the most widely used libraries in the ecosystem.

Summer is here. The stack doesn’t stop. Neither do we. Help us keep the NumFOCUS stack funded through summer and beyond. Support NumFOCUS today: hubs.la/Q04hMyGl0
