A country’s standing in global #OpenSource isn’t bought — it’s built. Our State of Public Code report shows public code contribution is tied more closely to digital maturity than to wealth alone. https://www.softwareheritage.org/2026/07/01/public_code_2026_launch/ #GovTech #FOSS #OSS

From dependence to resilience: Digital sovereignty for software https://www.softwareheritage.org/2026/06/26/dependence-to-resilience-digital-sovereignty-software/

From dependence to resilience: Digital sovereignty for software - Software Heritage

Roberto Di Cosmo returned to the University of Pisa — where he studied in the 1980s — to make the case that Europe’s digital sovereignty debate is missing its most critical pillar: software. A talk on fragility, dependency, and why resilience is not the same thing as control.

What are we missing when we talk about ethics and research in the digital age? Roberto Di Cosmo reframed the "data altruism" debate by shifting the focus to something more foundational: the code. #DigitalSovereignty #OpenSource

No science without source: Collecting, preserving and sharing software in a risky world - Software Heritage

Roberto Di Cosmo reframes data altruism to address the critical, missing pillar of digital sovereignty: the preservation of software code.

We’ve published the world’s first government #OpenSource insights report. It looks at how governments are using open source to deliver public services + opportunities and challenges ahead. More on the State of Public Code: https://www.softwareheritage.org/2026/07/01/public_code_2026_launch/

Always great to see the #SWHID in the wild ⭐ Ambassador Mohammad Akhlaghi shared a new #MNRAS paper detailing a rare nebula discovery that's challenging astrophysics models—backed by permanently archived, citable code. Read it here: https://doi.org/10.48550/arXiv.2606.24398

Discovery of a nebula associated with a high proper motion sdB star

All B-type subdwarf stars (hereafter sdB) should have low flux of ionizing photons, making them incapable of producing a noticeable circumstellar photoionized shell. However, a few sdB stars have been associated with circumstellar nebulae, resembling in some cases a planetary nebula. These discoveries spark doubts about the nature of the physical processes behind the formation of the nebula. In this paper, we describe the newfound parabolic-shaped nebula associated with the high proper motion sdB star TYC 3315-1807-1. The apex of the Halpha nebula is situated approximately 0.5 arcmin in the direction of the stellar proper motion. A wider parabolic-shaped nebula is also detected in WISE W1 infrared images at 3.4 micron, whereas GALEX images show extended far-UV emission around the star within the optical and mid-IR emissions. Like most other sdB stars with associated nebulae, TYC 3315-1807-1 moves at a high-speed (102 km/s) across the Galactic plane. The low luminosity of TYC 3315-1807-1 cannot provide its wind with the momentum necessary to form and keep a bow shock. The nebula around TYC 3315-1807-1 is rather suggested to be a Mach wave partially excited by shocks and photoionization or the encounter of the star with an over-density clump in the ISM.

Reflecting on his organization’s ten year history, Bastien Guerry, Head of Partnerships at Software Heritage noted that sustaining open source is not only about preserving code, but also about strengthening the infrastructure and services that make collaboration, maintenance, and reuse possible.

Roberto Di Cosmo is on a panel at #VivaTech today, 2pm CET — digital sovereignty through open infrastructure, with Meredith Whittaker, Adriana Groh, Henri Verdier, Luca Belli. https://vivatech.com/sessions/session/6a3958c7-2a60-f111-8fcb-6045bd954326 #OpenSource

Free, Open and Commons: New Paths to Sovereignty - [Session VivaTech] - Theme: undefined

Location: Sovereignty Arena - June 17 2:00 PM 2:55 PM - CET | Resume: At a time when key technologies are concentrated in the hands of a few global actors, sovereignty is most often thought of in terms of competition between powers. But what if it could be built differently? From digital commons - code, data, open infrastructures - emerges an approach of shared digital sovereignty, more collective, more interoperable, and more sustainable, as an alternative to the logic of rivalry.
