2. Queens Public library under ransomware attack e-borrowing suspended
⭐ 56 💬 37 👤 rustyhancock 🔗 Discuss on HN
Queens Public Library is experiencing a significant network outage caused by a ransomware attack, disrupting its website, mobile app, digital media services, and many public computers. All locations remain open for borrowing and returning materials, but renewals and e-borrowing are unavailable while systems are restored.
3. Claude Fable 5.2 and Mythos 5.2
⭐ 659 💬 840 👤 lairv 🔗 Discuss on HN
Claude Fable 5.2 and Mythos 5.2 are upgraded versions of the same underlying model, designed for demanding technical work with stronger coding, reasoning, and vision capabilities. They are intended for ambitious, open-ended tasks, with Fable broadly available and Mythos accessible through verification programs for beneficial cybersecurity and biomedical applications. The models also include enhanced safety and alignment testing, including protections against misuse and distillation attacks.
4. USPS now offers official ZIP Code boundary polygons
⭐ 636 💬 320 👤 munro 🔗 Discuss on HN
The USPS is making official ZIP Code boundary polygon data available. This provides precise geographic outlines of ZIP Codes for mapping, analysis, and location-based applications.
5. Fossil CO2 emissions decrease by 0.4% in 2026
⭐ 26 💬 14 👤 giuliomagnifico 🔗 Discuss on HN
Global fossil fuel CO2 emissions are projected to fall by 0.4% in 2026, driven by rapid growth in solar and wind power and a short-term oil decline linked to the Iran conflict. However, total CO2 emissions including land-use change are expected to rise to 43.3 billion tonnes, and clean-energy expansion is still not fast enough to ensure a lasting decline. The remaining carbon budget for limiting warming to 1.5°C is now about 150 billion tonnes, equivalent to less than four years of emissions at current rates.
6. Your TV can see through walls
⭐ 148 💬 51 👤 Curiositry 🔗 Discuss on HN
A simple radio receiver can detect movement behind walls by observing how a person’s body reflects and interferes with a wideband TV signal. When the reflected signal cancels the direct signal at certain frequencies, the resulting fading pattern changes as the person moves, allowing the receiver to infer motion and even estimate walking speed. The same principle can be applied to other wideband signals such as WiFi or LTE.
7. Fireworks AI security breach impacts Notion and their customers
⭐ 67 💬 20 👤 werrett 🔗 Discuss on HN
A security breach at Fireworks AI, a third-party AI infrastructure vendor used by Notion, may have exposed unattributable Notion AI chat transcripts from fewer than one percent of workspaces. The exposed data did not include tool call results or information identifying users, workspaces, or companies, and no other workspace data was affected. Notion disabled the affected Insights feature, stopped using Fireworks for open-weight models, and is providing affected workspace owners access to review the impacted data.
8. AI usage generates a fragile codebase
⭐ 65 💬 49 👤 plun9 🔗 Discuss on HN
The article argues that heavy reliance on AI coding tools can produce fragile, poorly maintained codebases. It identifies problems such as shallow tests, unnecessary complexity, reduced human understanding, and review pressure that allow technical debt to accumulate in large-scale software.
9. Locating the source of a mysterious beep
⭐ 217 💬 100 👤 bigwheels 🔗 Discuss on HN
A developer created Beep Locator, a software system that turns several phones, tablets, and laptops into microphones to triangulate the source of an intermittent beep in a cluttered room. After calibrating device positions and confirming the beep’s frequency, the system narrowed the sound to within about 40 centimeters. The source turned out to be an old carbon monoxide detector that needed new batteries.
10. Billion Watts in the Speaker [video]
⭐ 24 💬 10 👤 Element_ 🔗 Discuss on HN
The post likely shares a video of a speaker or audio system being driven with an absurdly high power level, possibly as a demonstration of loudness or speaker limits. It probably shows the resulting sound, distortion, or physical effects from the extreme input.
