Kolibri is a mixture-of-experts model with 78B total parameters but only about 3.5B active per token, released under Apache 2.0 with weights on Hugging Face. It was trained from scratch on German and Finnish infrastructure and designed with the EU AI Act in mind. The author discusses its strengths, weaknesses, how to run it, and when it is a good fit. It also shares one tokenizer experiment and draws from Aleph Alpha's technical report and launch materials.

2. Woking Electrical Control Room (2016) (57 points by NaOH)

   This is an urbex photography post about the disused Woking Electrical Control Room in the UK. Built in 1936, it was one of five control rooms for electricity on the Southern Rail network and was designed by James Robb Scott with construction by a Swedish firm. The room features an oval, white-domed ceiling, a central switchboard, decorative cast-iron poles with copper dishes, and wall panels controlling substations along the line. It remained in use until 1997 and could be operated by only two on-site engineers, despite the ironic need to wind up the telephone switchboard.

3. Kolibri Has Landed: A Sovereign Open-Weight Model (166 points by bastitx)

   This is Aleph Alpha's official launch post for Kolibri, a sovereign open-weight English-German model. Kolibri is a mixture-of-experts Transformer with 78B total parameters, 3B active, and support for up to 1M tokens of context. Its full weights are available on Hugging Face under Apache 2.0. The post frames Kolibri as the result of an iterated training pipeline, following Kolibri Origin, and as a specialized model for mission-critical regulated sectors such as public administration, industrial, and aerospace.

4. FTL: A new operating system for clouds (10 points by romac)

   FTL is a proposed operating system design for clouds where each container runs its own userspace OS as a library. The FTL kernel provides a minimal hypervisor-like interface and isolates containers better than traditional monolithic kernels using lightweight user-mode hardware isolation. It remains compatible with Linux binaries, so ordinary Linux applications can run on it, while also supporting unikernel-like specialized applications without POSIX abstractions. The project aims to make lightweight containers as secure as VMs without sacrificing performance.

5. Newgrounds.com – A community of games, music, and art (359 points by azhenley)

   This link points to Newgrounds.com, a long-running community platform for user-submitted games, music, and art. Rather than a news article, it is the site's homepage, which HN users upvoted heavily, likely reflecting nostalgia and appreciation for independent web creativity. Newgrounds is historically associated with browser games, animation, and early internet creator culture. Its presence here highlights continued interest in open, community-driven creative platforms.

6. C++ Insights – See your source code with the eyes of a Compiler (63 points by rramadass)

   C++ Insights is an open-source tool by Andreas Fertig that shows C++ source code from the compiler's perspective. It transforms code to make implicit compiler behavior explicit, helping developers understand constructs such as lambdas, range-based for loops, templates, and coroutines. The GitHub repository has thousands of stars and active development. It is primarily an educational and debugging aid for C++ developers who want to see how their source is interpreted.

7. Court agrees with EFF: Utah's VPN law demands a technical impossibility (709 points by hn_acker)

   This EFF article reports that a federal court agreed with EFF and blocked Utah's VPN law with a preliminary injunction. The law attempted to restrict VPN privacy protections in ways EFF argues are technically impossible to implement. The court's decision is framed as a win for digital rights and for the principle that lawmakers cannot require impossible technical behavior. The case reflects broader tensions between state regulation, privacy tools, and how the internet actually works.

8. Body Awareness in Goffin's Cockatoos (3 points by bryanrasmussen)

   This Scientific Reports study tests body awareness in Goffin's cockatoos using a bird-adapted body-as-obstacle paradigm. Fifteen cockatoos had to retrieve and pass an object to an experimenter, with the key test attaching the object to the mat they stood on, requiring them to step off. Control conditions and a pre-test ruled out simple movement or discomfort explanations. The birds performed near ceiling on the pre-test and stepped off the mat far more often in the test condition, suggesting they recognized their own body as an obstacle.

9. Apple Pass Designer (498 points by soheilpro)

   Apple Pass Designer is a developer tool for creating and previewing Wallet passes such as loyalty cards, tickets, and boarding passes. It offers Apple or custom templates, image import, real-time previews on iPhone and Apple Watch using the same rendering as iOS and watchOS, and controls for colors, layouts, and fields. It validates passes as you edit and warns about missing required values or unexpected definitions. It also supports semantic tags for boarding passes and event tickets, adding structured data for those use cases.

10. Mike Tomlin spent 12 years building a Minecraft city (575 points by CoryOndrejka)

    This New York Times Athletic article profiles NFL coach Mike Tomlin and his 12-year project building a city in Minecraft. Although the preview content is unavailable, the title indicates a feature about a long-running personal creative hobby alongside his coaching career. The high HN score suggests interest in the unexpected intersection of professional sports, gaming, and long-term world-building. It may explore themes of patience, craft, and private passion outside public work.
