After building Nuanced, a desktop coding app centered on planning, Ayman Nadeem concluded that plan modes are obsolete. Models now infer context and make reasonable assumptions, eliminating the need for detailed specs. AI-generated plans are painful to read, and separating planning from building creates a rigid waterfall. The real challenge remains: helping humans maintain a coherent mental model as AI agents change code faster than we can inspect. - Appeals Court Backs Pentagon's Blacklisting of Anthropic — ▲ 486 · 💬 853 · 🔗 cnbc.com
A federal appeals court in Washington, D.C., on Friday upheld the Pentagon's designation of Anthropic as a supply chain risk, keeping the AI giant on the government's blacklist. The ruling affirms the earlier decision and marks a significant setback for Anthropic in its fight against the national security label. - Go 1.27 brings platform-independent SIMD to the language — ▲ 401 · 💬 146 · 🔗 go.dev

Cinebench 2000 scores show the emulated system rivaling a Pentium III 800MHz. - First Principles Thinking Is the New Flow State for Engineers in the Agentic Era — ▲ 280 · 💬 127 · 🔗 sunilsadasivan.com
Drawing on Sunil Pai's essay on the senior engineer death spiral, this piece argues that the best senior engineers share a habit of first-principles thinking: asking why we're building something and what it does for users. In the shift to agentic development, that means putting your hard-won experience in a box long enough to see the problem fresh. The payoff is faster learning loops and momentum oriented around deep understanding. - Gravity May Be Holographic, and That Would Mean Space Isn't What It Seems — ▲ 278 · 💬 217 · 🔗 quantamagazine.org
The holographic principle suggests that everything inside a region of space can be reconstructed from its surface alone — a radical idea that has become one of the most cited proposals in theoretical physics. This essay traces the evidence from black hole entropy to the AdS/CFT correspondence, weighs skeptics' objections, and asks what it would mean for our universe if gravity truly is holographic. - Jev Plays Pokémon Red - AI Plays Pokémon with Live Decision Panel — ▲ 259 · 💬 109 · 🔗 jev-pokemon.vercel.app

They highlight concerns about privacy, bias, and chilling effects while sarcastically praising the surveillance as a loving gift from Big Brother Tech. - Ask HN: Who's still keeping a DOS machine up because the business depends on it? — ▲ 241 · 💬 254
I'm doing research for an idea around keeping legacy DOS-based systems running on modern hardware. I want to hear from anyone who currently works with or knows someone still using dBase/Clipper/CLARION/Paradox or other DOS RAD environments on period hardware, or industrial instruments controlled by ISA cards (bespoke or standards like GPIB), or anything with a parallel port dongle. I'm not selling anything—just gathering experiences. - Italy's Mafia May Be Quietly Keeping Fentanyl Out of the Country — ▲ 201 · 💬 266 · 🔗 economist.com
Italy's low overdose rate has puzzled observers, and police now suspect an unlikely explanation: the country's mafias have collaborated to keep fentanyl off their turf. The article draws a parallel to The Godfather, in which Don Vito Corleone refuses to enter the heroin trade as "a dirty business" — scruples that are rare among real mafiosi, yet may have played out in Italy over the past decade. - The FAA Banned Baby Carriers on Planes Without Testing the Obvious Alternative — ▲ 198 · 💬 270 · 🔗 jefftk.com
The FAA's rule against using baby carriers during takeoff and landing stems from a 1994 study that tested car seats and belly belts but never compared carriers to the most common practice: holding a baby in your lap. The agency applied thoughtful substitution analysis when deciding not to ban lap infants, but failed to do the same here. A 2024 bill to fix this died in subcommittee. - NSA Spends Billions Testing AI Models, Far More Than Previously Known — ▲ 176 · 💬 105 · 🔗 washingtonsun.com
The National Security Agency is spending billions of taxpayer dollars this year to evaluate advanced AI models, according to classified estimates shared with lawmakers.

The NSA's Artificial Intelligence Security Center tests frontier models for national security vulnerabilities, and the expense—driven by computing power and scarce talent—is fueling debate over whether AI companies should help foot the bill. - Jensen Huang Says Kids Forgetting Math Doesn't Matter, and That's a Test We Should Fail — ▲ 166 · 💬 88 · 🔗 tante.cc
Jensen Huang told Ezra Klein he doesn't know his own address or ZIP code and doesn't care that kids are forgetting basic math. The author argues these aren't just rich-guy quirks but loyalty tests: when tech leaders say absurd things, those who nod along prove their obedience. The only way to win is to fail the test loudly and publicly. - Oracle must pay data centre investors even if the site has no electricity — ▲ 156 · 💬 152 · 🔗 ft.com
Oracle has signed contracts obliging it to keep paying data centre investors even when a site has no power, the Financial Times reports. The arrangement shifts risk from landlords to the cloud company, which is spending heavily on AI infrastructure. It raises questions about how much exposure Oracle carries if projects stall or fail to secure electricity. - Microsoft Abandons Personal AI Chatbot Race With Copilot Reboot — ▲ 143 · 💬 136 · 🔗 bloomberg.com
Microsoft is merging its consumer and workplace Copilot AI assistants into a single product aimed at corporate customers, effectively ceding the personal chatbot market to OpenAI, Google, and Meta.

During a live Zoom talk for Kristen Nygaard's 100th birthday, Alan Kay's own voice kept returning to his ears about 21 seconds late, thanks to an open mic near a speaker. Instead of ignoring it, he riffed on Claude Shannon's noisy channel coding theorem — the very math describing the garbled channel he was praising. Commenters compare the accident to Alvin Lucier's "I Am Sitting in a Room." - Meta's Muse appears to use an OpenAI model labeled muse-special — ▲ 142 · 💬 49 · 🔗 mouse.dev
After my previous post on Muse's runtime export hit Hacker News, I dug deeper into the filesystem and found a single session using a model labeled azure/muse-special. The logs show OpenAI-style call IDs and an encrypted gpt_responses_v1 signature, suggesting it's a GPT model served through Azure. The model catalogue also includes Claude and GPT variants, and there's Anthropic client code with a kill switch. I explore whether Meta is distilling from OpenAI or Anthropic, but the encrypted reasoning and RL server restrictions suggest not. This is my own exploration of a fascinating release. - I lined up at 3 a.m. for the first iPhone. Now I can't name the one in my pocket. — ▲ 141 · 💬 158 · 🔗 matduggan.com
A former smartphone evangelist traces how the device became a tax: mandatory apps for school, trains, and government in Denmark, an App Store drowning in ads, and streaming that interrupts shows with gambling spots. The only relief he found was a MiSTer FPGA console and NFC cards—an offline object that never asks for an account. - Why Amiga Screens Still Amaze: A Primer on the 1985 Multitasking Marvel — ▲ 137 · 💬 51 · 🔗 datagubbe.se
Amiga screens let you drag entire display areas, each with its own resolution and color depth, thanks to the copper co-processor and planar graphics.

The result is nearly identical to the original, minus some post-processing effects. - AI Safety Is Mostly a Sex Cult in Berkeley, California — ▲ 120 · 💬 30 · 🔗 verysane.ai
The author argues that the AI safety movement is fundamentally shaped by Eliezer Yudkowsky and his rationalist community, which he describes as a predatory sex cult. He traces Yudkowsky's influence on major AI figures like Sam Altman, Dario Amodei, and Demis Hassabis, and claims that Effective Altruism in the Bay Area is largely a front for Yudkowsky's ideas. The piece contends that these people should not be making AI policy. - Avast Antivirus Sandbox Hacked via Double-Fetch Bug in Kernel Driver — ▲ 115 · 💬 30 · 🔗 safateam.com
Researchers detail CVE-2025-13032, a double-fetch flaw in Avast's kernel driver that triggers a paged pool overflow.

TAI-DR stands for "Too AI; Didn't Read" — a response to the flood of AI-generated text people forward without reading. The site frames it as a boundary, not an acronym problem: if you couldn't bother to read it, why should I? It's not anti-AI, but pro-giving-a-damn. Use the tools, do the thinking, read before you send. The site invites visitors to share their own slop stories and browse others'. - Claude Solves a Nine-Loop Physics Problem That Stumped Experts — ▲ 103 · 💬 62 · 🔗 anthropic.com
Physicist Matt von Hippel challenged AI companies to compute a nine-loop scattering amplitude in N=4 super Yang-Mills, a task expected to require massive computational resources. Anthropic researchers used Claude Science to solve it for about $100 in compute, matching a result humans achieved around the same time. The episode suggests there is more low-hanging fruit in theoretical physics than experts assume. - Russia widens strikes to hit Ukraine's data centres, Zelensky says — ▲ 99 · 💬 137 · 🔗 bbc.com
Zelensky says Russia has expanded its attacks to target Ukraine's data centres and internet providers, aiming to cause maximum disruption to daily life. A drone strike on a Kyiv business centre killed four people and damaged a data centre; about 100,000 households lost internet. Russia confirmed hitting a data centre it claims was used by Ukrainian military intelligence. Ukraine's foreign minister calls these critical civilian infrastructure, not military targets. - New Jersey fines data center $1.1M after drone photos reveal 62 unpermitted gas generators — ▲ 94 · 💬 29 · 🔗 arstechnica.com
New Jersey fined DataOne $1.1 million for secretly operating 62 gas generators without permits at its Vineland data center, following a Guardian and Floodlight investigation that used thermal drone footage to show 45 generators running.

Laura Bassett posted on Bluesky that someone sent her a Chase ad featuring an AI version of her. She asked what she should do. The post does not name the ad, explain how the AI likeness was made, or say whether Chase authorized it. It raises a real question about consent and control when a bank ad appears to use a synthetic version of a real person. - Ask HN: Hypothesis: Cellular providers are deprioritizing voice calls — ▲ 20 · 💬 38
I switched from Verizon to T-Mobile because I was experiencing too many silent missed calls, where my iPhone never rang and no missed call appeared. This happened across multiple devices, on both Wi-Fi and cellular, with Wi-Fi calling enabled and disabled, and with frequent contacts as well as new callers. After a year on T-Mobile, the problem is about the same as Verizon, and I still regularly miss calls without any notification. I hypothesize that since many subscribers use voice calls less, cellular providers have found they can reduce voice call quality without losing customers. - Step Into the Last Day of the Dinosaurs in an Interactive 2.5D Painting — ▲ 19 · 💬 17 · 🔗 echohive.ai
EchoHive's The Last Day is an interactive 2.5D painting set in Cretaceous Hell Creek, 66 million years ago. Seven movements follow one golden evening from dusk to the Chicxulub impact, darkness, and survival, with painted dinosaurs, trees, water, and skies layered in depth. Drag to look, scroll to move closer, and use the timeline to travel through the scene, all driven by a single soundtrack. It is an artistic interpretation, not a simulation. - When Chrome, Firefox, and Safari All Agree, the Spec Is the One That Changes — ▲ 14 · 💬 6 · 🔗 atbrakhi.dev
When browsers agree on behavior that contradicts the written specification, the fix isn't always three browser bugs. Sometimes the spec itself gets updated. Drawing on a real case where newline normalization in HTML form submissions diverged from the spec, this piece explores how browser implementations and specifications co-evolve, why convergence matters more than correctness, and how the Web's memory turns old bugs into compatibility constraints. - Calibration, Not Speed, Is the Real Bottleneck for Production Classifiers — ▲ 13 · 💬 11 · 🔗 kartikpansuriya.com
TypeSafe AI's Jev, a non-autoregressive System One model, promises calibrated probabilities in a single forward pass. Drawing on his COMPSAC paper where a Random Forest hit F1 0.958 but a majority baseline hit 0.957, the author argues calibration is what limits production classifiers. He outlines an experiment comparing Jev, a calibrated forest, and an LLM on PR acceptance, measuring Brier score and expected calibration error. - AGI Is Here, but Companies Are Still Built for the Pre-AGI World — ▲ 13 · 💬 53 · 🔗 avidfayaz.com
The author argues that AGI has arrived as a threshold of generality and autonomy, yet most organizations still use AI as a tool to make humans better at existing work. The real post-AGI shift is redesigning companies around autonomous agents that collaborate, evaluate one another, and recursively improve their own systems. He describes building such an organization at Infinite Ascent, with trading agents, reviewers, a meta-harness, and an internal IT department for agents. - Roads About - Discover US roads by 1,068 themes — ▲ 13 · 💬 9 · 🔗 road-about-a-theme.pinedesk.biz

In a controlled LangGraph Agent Server test, a maker replaced a pending wire transfer of 20 units with one of 2,000 units to an attacker sink, then an approver's stale decision released the larger transfer. The attack exploits A2A Task and tool-call IDs that stay the same while arguments change, so an implementation that checks only that a Task was approved can spend that approval on a different operation. The flaw is implementation-side, not a core A2A vulnerability.
