The Open Document Format reached its 20th anniversary on May 1, marking two decades since OASIS approved the XML-based standard originally developed by Sun Microsystems from StarOffice code. Even as the format has seen adoption by several governments including the UK, India, and Brazil, plus organizations like NATO, Microsoft Office's proprietary formats remain the de facto standard.
Microsoft countered ODF by developing Office Open XML, eventually getting it standardized through Ecma International. "ODF is much more than a technical specification: it is a symbol of freedom of choice, support for interoperability and protection of users from the commercial strategies of Big Tech," said Eliane Domingos, Chair of the Document Foundation, which oversees LibreOffice -- a fork created after Oracle acquired Sun.

Longtime Slashdot reader RoccamOccam shares a blog post from the Trifecta Tech Foundation, a nonprofit organization that creates secure, open source building blocks for infrastructure software. The foundation is also the developer behind Sudo-rs. From the report: Ubuntu 25.10 is set to adopt sudo-rs by default. Sudo-rs is a memory-safe reimplementation of the widely-used sudo utility, written in the Rust programming language. This move is part of a broader effort by Canonical to improve the resilience and maintainability of core system components. [...]
The decision to adopt sudo-rs is in line with Canonical's commitment to Carefully But Purposefully increase the resilience of critical system software, by adopting Rust. Rust is a programming language with strong memory safety guarantees that eliminates many of the vulnerabilities that have historically plagued traditional C-based software. Sudo-rs is part of the Trifecta Tech Foundation's Privilege Boundary initiative, which aims to handle privilege escalation with memory-safe alternatives.

Did you know there's an initiative to drive Open Source adoption both within the United Nations — and globally? Launched in March, it's the work of the Digital Technology Network (under the UN's chief executive board) which "works to advance open source technologies throughout UN agencies," promoting "collaboration and scalable solutions to support the UN's digital transformation." Fun fact: The first group to endorse the initiative's principles was the Open Source Initiative...
"The Open Source Initiative applauds the United Nations for recognizing the growing importance of Open Source in solving global challenges and building sustainable solutions, and we are honored to be the first to endorse the UN Open Source Principles," said Stefano Maffulli, executive director of OSI.
But that's just the beginining, writes It's FOSS News: As part of the UN Open Source Principles initiative, the UN has invited other organizations to support and officially endorse these principles. To collect responses, they are using CryptPad instead of Google Forms... If you don't know about CryptPad, it is a privacy-focused, open source online collaboration office suite that encrypts all of its content, doesn't log IP addresses, and supports a wide range of collaborative documents and tools for people to use.
While this happened back in late March, we thought it would be a good idea to let people know that a well-known global governing body like the UN was slowly moving towards integrating open source tech into their organization... I sincerely hope the UN continues its push away from proprietary Big Tech solutions in favor of more open, privacy-respecting alternatives, integrating more of their workflow with such tools.
16 groups have already endorsed the UN Open Source Principles (including the GNOME Foundation, the Linux Foundation, and the Eclipse Foundation).
Here's the eight UN Open Source Principles:

"Researchers have created the first laboratory analog of the 'black hole bomb'," reports ScienceAlert, "a theoretical concept developed by physicists in the 1970s..."
There's no black hole involved; their experiment just simulates the "electromagnetic analogue" of the theoretical concept — the "exponential runaway amplification of spontaneously generated electromagnetic modes."
Or, as ScienceAlert puts it, "It doesn't, just to set your mind at ease, pose any danger. It consists of a rotating aluminum cylinder, placed inside layers of coils that generate magnetic fields that rotate around it, at controllable speeds." As Roger Penrose proposed in 1971, the powerful rotational energy of a spinning black hole could be used to amplify the energy of nearby particles. Then, physicist Yakov Zel'Dovich figured out that you didn't need a black hole to see this phenomenon in action. An axially symmetrical body rotating in a resonance chamber, he figured, could produce the same energy transfer and amplification, albeit on a much smaller scale. Later work by other physicists found that, if you enclose the entire apparatus in a mirror, a positive feedback loop is generated, amplifying the energy until it explodes from the system.
This concept was named the black hole bomb, and a team of physicists led by Marion Cromb of the University of Southampton in the UK now claim to have brought it to life. A paper describing their experiment has been uploaded to preprint server arXiv... [W]hat the team's experiment does is simulate it, using magnetic fields as a proxy for the particles, with the coils around the system acting as the reflector to produce the feedback loop. When they ran the experiment, they found that, when the cylinder is rotating faster than, and in the same direction as, the magnetic field, the magnetic field is amplified, compared to when there is no cylinder. When the cylinder rotates more slowly than the magnetic field, however, the magnetic field is dampened. This is a really interesting result, because it demonstrates a very clear amplification effect, based on the theories described decades ago...
Because we can't probe black holes directly, analogs such as this are an excellent way to understand their properties... [T]he experiment could represent a significant step towards better understanding the physics of the most gravitationally extreme objects in the Universe.
"The exponential amplification from noise supports theoretical investigations into black hole instabilities," the researchers write, "and is promising for the development of future experiments to observe quantum friction in the form of the Zeldovich effect seeded by the quantum vacuum..."

NASA's SPHEREx space observatory has officially begun its two-year mission to map the entire sky in 102 infrared wavelengths, capturing about 3,600 images daily to create 3D maps of hundreds of millions of galaxies. Its goal is to unlock new insights into cosmic inflation, the origins of galaxies, and the building blocks of life in the Milky Way by using spectroscopy to analyze light and matter across the universe. From a press release: From its perch in Earth orbit, SPHEREx peers into the darkness, pointing away from the planet and the Sun. The observatory will complete more than 11,000 orbits over its 25 months of planned survey operations, circling Earth about 14.5 times a day. It orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky. As the days pass and the planet moves around the Sun, SPHEREx's field of view shifts as well so that after six months, the observatory will have looked out into space in every direction.
When SPHEREx takes a picture of the sky, the light is sent to six detectors that each produces a unique image capturing different wavelengths of light. These groups of six images are called an exposure, and SPHEREx takes about 600 exposures per day. When it's done with one exposure, the whole observatory shifts position -- the mirrors and detectors don't move as they do on some other telescopes. Rather than using thrusters, SPHEREx relies on a system of reaction wheels, which spin inside the spacecraft to control its orientation.
Hundreds of thousands of SPHEREx's images will be digitally woven together to create four all-sky maps in two years. By mapping the entire sky, the mission will provide new insights about what happened in the first fraction of a second after the big bang. In that brief instant, an event called cosmic inflation caused the universe to expand a trillion-trillionfold.
