The Apache Software Foundation has unveiled a major branding overhaul that retires its three-decade-old feather logo after criticism from Native American activists. In its place is a new oak leaf design to symbolize endurance, resilience, and global reach. Along with the new visual identity, the group will emphasize "The ASF" as its shorthand name while keeping its full legal title intact.

Apache.org explained: "The oak is one of the most enduring trees and is found around the world. It grows slowly but steadily, supporting vast ecosystems and lasting for centuries. In the same way, The ASF has served as a stable, resilient steward of open source for more than 25 years and is looking to the long future ahead. Choosing the oak leaf as our new logo represents the enduring power of our ethos: community over code."

Physicists have confirmed Stephen Hawking's 1971 black hole area theorem with near-absolute certainty, thanks to gravitational waves from an exceptionally loud black hole collision detected by upgraded LIGO instruments. New Scientist reports: Hawking proposed his black hole area theorem in 1971, which states that when two black holes merge, the resulting black hole's event horizon -- the boundary beyond which not even light can escape the clutches of a black hole -- cannot have an area smaller than the sum of the two original black holes. The theorem echoes the second law of thermodynamics, which states that the entropy, or disorder within an object, never decreases.

Black hole mergers warp the fabric of the universe, producing tiny fluctuations in space-time known as gravitational waves, which cross the universe at the speed of light. Five gravitational wave observatories on Earth hunt for waves 10,000 times smaller than the nucleus of an atom. They include the two US-based detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) plus the Virgo detector in Italy, KAGRA in Japan and GEO600 in Germany, operated by an international collaboration known as LIGO-Virgo-KAGRA (LVK).

The recent collision, named GW250114, was almost identical to the one that created the first gravitational waves ever observed in 2015. Both involved black holes with masses between 30 and 40 times the mass of our sun and took place about 1.3 billion light years away. This time, the upgraded LIGO detectors had three times the sensitivity they had in 2015, so they were able to capture waves emanating from the collision in unprecedented detail. This allowed researchers to verify Hawking's theorem by calculating that the area of the event horizon was indeed larger after the merger. The findings have been published in the journal Physical Review Letters.

Germany has already met its 2028 goal for reducing coal-fired power generation, so won't need to order the shutdown of any plants for a second year running, the country's regulator said. From a report: Germany has an interim 2028 target of reducing coal-fired power by 8.7 gigawatts, and as of Sept. 1 it had exceeded this level by about 10%, the Federal Network Agency said on its website on Monday.

Almost two thirds of Germany's electricity comes from renewables and excess solar power production has frequently pushed prices below zero, making burning coal less profitable. Yet Europe's largest economy remains heavily dependent on the fossil fuel and is still the European Union's biggest polluter.

FFmpeg 8.0 brings GPU-accelerated video encoding via Vulkan -- and can now subtitle your videos automatically using integrated speech recognition. From a report: At the start of the week, the FFmpeg project released its eighth major version. It's codenamed "Huffman" after the Huffman code algorithm, which was invented in 1952, making it one of the oldest lossless compression algorithms.

[...] The changelog lists 30 significant changes, of which the top new feature is integrating Whisper. This means whisper.cpp, which is Georgi Gerganov's entirely local and offline version of OpenAI's Whisper automatic speech recognition model. The bottom line is that FFmpeg can now automatically subtitle videos for you.

The Document Foundation, which operates the popular open source productivity suite LibreOffice, is positioning the suite's newest release, v25.8, as a strategic asset for digital sovereignty, targeting governments and enterprises seeking independence from foreign software vendors and cloud infrastructure.

The Document Foundation released the update last week with zero telemetry architecture, full offline capability, and OpenPGP encryption for documents, directly addressing national security concerns about extraterritorial surveillance and software backdoors. The suite requires no internet access for any features and maintains complete transparency through open source code that governments can audit. Government bodies in Germany, Denmark, and France, alongside national ministries in Italy and Brazil, have deployed LibreOffice to meet GDPR compliance, national procurement laws, and IT localization mandates while eliminating unpredictable licensing costs from proprietary vendors.

"It's time to own your documents, own your infrastructure, and own your future," the foundation wrote in a blog post.
