Today’s Top 10 on Hacker News
1. GPT-6 Astra
⭐ 1853 💬 1645 👤 kibae 🔗 Discuss on HN
OpenAI has unveiled GPT-6 Astra, its newest flagship model, with a staged rollout that begins with a limited set of organizations and expands to ChatGPT Plus, Pro, Business, and Enterprise subscribers, the OpenAI API, and AWS over the coming days. Astra is positioned as an agent that operates inside software — driving tools, building and testing, and juggling multiple documents and tasks at once. Notably, it is the first OpenAI model to meet the company’s critical cybersecurity capability threshold.
2. .name Termination
⭐ 1872 💬 459 👤 pavel_lishin 🔗 Discuss on HN
In a personal account, Neil Fraser describes how Verisign proposed destroying the entire third level of the .name domain hierarchy and ICANN approved it in July. The change will terminate 22,000 registered names — including his, paid for until 2040 — wiping out his website, email address, and IoT services in February. He warns that the vacant second-level domains could then be re-registered by strangers, letting them hijack decades of accounts tied to those addresses.
3. Carbon-aware electricity pricing, measured daily on 38 grids
⭐ 39 💬 16 👤 High-Five 🔗 Discuss on HN
A live dashboard tests carbon-aware electricity pricing on real grid data across Switzerland and 38 US grid regions, comparing three schemes — a fixed standard tariff, hourly carbon-aware pricing, and sharp peaks during the dirtiest hours — and measuring the CO2 savings each would achieve against today’s pricing.
4. The Raspberry Pi Interactive Timeline · 2006–2026
⭐ 30 💬 23 👤 mariuz 🔗 Discuss on HN
An interactive timeline traces two decades of the Raspberry Pi, from Eben Upton’s Cambridge idea in 2006 through the Foundation’s 2009 founding, the $35 Model B launch on leap day 2012, and the move of production to Wales. It catalogs the hardware, software, and corporate milestones that made it the best-selling British computer, with sourced entries for each year.
5. Solving the Jane Street Reverse Engineering Challenge
⭐ 16 💬 5 👤 anitil 🔗 Discuss on HN
A developer recounts a month-long, sleep-deprived attempt to reverse-engineer Jane Street’s ASIC challenge — recovering what a chip does from a GDS layout file. Using the gdstk Python library and a small C program on the accompanying VCD simulation file, he extracts hidden messages like ‘TRY AGAIN’ and works backwards from netlist primitives toward the underlying logic.
6. Qwen 3.8 27B available on Cerebras at 1500 tokens/s
⭐ 573 💬 190 👤 altertable 🔗 Discuss on HN
Cerebras has listed Qwen 3.8 27B among the models on its public inference endpoints, serving it at roughly 1,500 tokens/second with a 64k free / 128k paid context window, alongside its OpenAI gpt-oss-120b offering at ~3,000 tokens/s. The docs also detail its model-compression policy: public endpoints host only unpruned, original versions, with selective weight-only quantization used only for storage.
7. Authorization terminology is a mess: Let’s fix it
⭐ 54 💬 26 👤 andychiare 🔗 Discuss on HN
Elizabeth Garber argues that the vocabulary around authorization — authentication, authorization, roles, permissions, scopes — has drifted into inconsistency across security and identity products. Writing from IDPro, she proposes a tighter, shared set of terms so that teams and vendors stop using the same words to mean different things.
8. Hackers Had a Live Feed of Every ID Verification Company Scanned for over a Year
⭐ 184 💬 55 👤 beardyw 🔗 Discuss on HN
Security researcher Brian Krebs reports that hackers held a live feed of government IDs scanned by the Louisiana-based verification service IDScan for over a year. A dark-web site called Nexus advertised more than 150 million US and Canadian driver’s licenses and passports, adding hundreds of thousands of new documents daily — including Krebs’ own license and DOD secretary Pete Hegseth’s — before it went offline. The FBI is probing the breach.
9. The largest electric aircraft just flew [video]
⭐ 346 💬 237 👤 feb 🔗 Discuss on HN
Video shows the largest electric aircraft to date completing its flight, a milestone for all-electric aviation. The discussion on HN covers the energy-density limits that electric propulsion still faces, how this build compares with smaller electric planes, and what it means for the practicality of battery-powered flight.
10. Artificial beaver dams saw juvenile coho salmon survival rates go from 8% to 60%
⭐ 269 💬 85 👤 speckx 🔗 Discuss on HN
In California’s Scott River valley, where 1830s fur trappers wiped out the beavers whose dams created coho salmon habitat, the Scott River Watershed Council built artificial beaver dams from posts, willow, conifer, and mud. The structures recreated about 9,000 square metres of cold wetland habitat, and juvenile coho survival on French Creek jumped from 8% before the dams to 60% after.
