$12B of US ratepayers' money wasted on a modeling mistake in PJM
_delirium · Hacker News: Front Page · newsletter.semianalysis.com · 38 min
Using a reconstructed model of PJM’s Reserve Requirement Study, a new analysis estimates the market operator’s failure to credit winter turbine efficiency and mandated winterization left 3.8GW of reliable capacity unseen. That modeling error overstated the supply shortfall, wasting $12B of ratepayers’ money from 2025–2027 and driving the 17–24% bill jumps.
Anthropic's 'Watermark' Text Adulteration in Claude Is a Perversion of Writing
ropbear · Hacker News: Front Page · daringfireball.net · 22 min
Anthropic's semantic watermarking of all Claude output—picking 'green' and 'red' list words—is a perversion of writing, he argues: no two synonyms mean the same, and the EU compliance measure is applied worldwide. Google's SynthID illustrates the flaw (mango vs. pineapple), and Declaude already removes the marks.
Transcendental Longing
Charlie Lee · Harper's Magazine · harpers.org · 10 min
Critic Ian Penman discusses Alice Coltrane's interpretation of her suffering as tapasya, the condescension she endured from jazz critics, and the deeply emotional reaction her music evokes even in non-jazz listeners. He also weighs the virtues of writing about her in a hagiographical mode.

A 3rd World Embedded Engineer Responds to "RISC-V They Should Have Known Better"
Narishma · Hacker News: Front Page · rvembedded.com · 14 min
An embedded engineer in Trinidad responds to Dmitry Grinberg's RISC-V critique, arguing the architecture wins on price and accessibility, not elegance: a ten-cent CH32V003 and a $20 dual-core CH32H417 share the same base ISA, while ARM's low-to-high-end gap is a licensing wall. He reports exploring the whole stack for under $100, with Baochip's open MMU-enabled RISC-V SoC proving the boundary is not technical.
Markdown Is Not a Format, It's an Argument
LLBBL Blog · tyler's Top Finds on Scour Today · llbbl.blog · 8 min
Five parsers turn the same three lines of Markdown into five different documents, and one of them italicizes snake_case_variable. Tracing the format from Gruber's prose spec to CommonMark's two-pass algorithm and GFM's extensions, the essay argues that writing Markdown means writing in a dialect and hoping the reader speaks it.
The Case Against Formal Verification, 50 Years Later
ghuntley · Hacker News: Front Page · ivan-gavran.github.io · 7 min
Fifty years after a classic paper declared program verification 'bound to fail,' its six arguments are weighed against 2026's verification hype. LLM-powered provers, interactive specification languages like Quint, and Igor Konnov's Lean proof of the Ben-Or protocol undercut most of them—though the paper's warning that reliability needs more than verification still lands.
You can just choose how many bugs you want now
Nolan Lawson · Read the Tea Leaves · nolanlawson.com · 7 min
Bug-finding has become nearly free in AI-assisted coding, so developers can now basically choose how many bugs their software has — but overall tolerance for bugs hasn't changed. It digs into the epicycle problem (agents adding fix upon fix), the power of a strong test suite like Web Platform Tests, and the author's preference for simpler systems over complex ones.

Can’t whistle? It’s not you, it’s mouth geometry.
Jennifer Byrne · Popular Science · popsci.com · 6 min
Whistling isn't a rare gift but a matter of lip and tongue geometry, and for most people it's learnable, says acoustics researcher Francisco Ruiz. He has built the Flutino, a 3D-printed device that shapes the mouth correctly and can whistle at 100 decibels. A UCLA club is testing whether it teaches lifelong non-whistlers, while speech scientist Maureen Stone notes age matters: after puberty, the muscles become less adaptable.
The world’s largest electric plane takes flight
Mack DeGeurin · Popular Science · popsci.com · 6 min
Heart Aerospace's 30-seat X1 completes its maiden flight, flying 27 minutes on battery power alone. The piece scrutinizes the company's headline claim that the trip used just $5 of electricity, noting it excludes crew, maintenance and battery degradation, and explains why a hybrid-electric ES-30 with a 500-mile range is the more realistic next step.
A U.S. Strategy to Prevent the Creation of Mirror Life
thunderbong · Hacker News: Front Page · rand.org · 4 min
RAND researchers argue that mirror life—hypothetical organisms built from reversed-chirality biomolecules—could evade immune detection and cause irreversible ecological disruption within decades. They outline a U.S. strategy of collective restraint, emphasizing early engagement with China, transparent scientific collaboration, and a clear commitment never to develop mirror life, since secrecy and reactive governance would fail.

AI Coding Without the Vibes
riskone · Hacker News: Front Page · peterbloem.nl · 32 min
Rejecting both vibe-coding and its opposite, the essay proposes 'craft coding': write every line yourself, then let the AI act as a demanding code reviewer. A baking analogy (Hanna, Vivian, Cara) illustrates the middle path, and ten dogmas cover practice, with AI review catching bugs, improving security, and preventing most deskilling. An excerpt.
Qwen 3.8 27B is excellent, but it defaults to wildly overthinking things
Simon Willison · Simon Willison's Weblog · simonwillison.net · 10 min
The article tests Qwen 3.8 27B, a 17GB open model, and finds its default "extra high" reasoning effort leads to comical overthinking — generating a pelican SVG takes 21 minutes and 22k reasoning tokens. Despite that, it excels at bounding box annotation and runs a coding agent loop, though speed remains the bottleneck. Community optimizations like multi-token prediction boost throughput significantly.
The AI Credit Resale Economy
mlenhard · Hacker News: Front Page · vectoral.com · 4 min
Matt Lenhard investigates the commercialized market for resold AI credits, emailing brokers and listing his own credits on marketplaces to map how unused inference is bought and sold off-market. He finds brokers offering $100k in daily spend, sites advertising 30–80% discounts, and tens of millions of credits in circulation — with abuse likely to follow as the market turns.
What happens when an LLM never sees material beyond fifth grade?
porridgeraisin · Hacker News: Front Page · littlelearner-ll.github.io · 3 min
Researchers train 0.6B–5B language models from scratch on an 88B-token corpus filtered to the U.S. K–5 curriculum, alongside matched unfiltered controls. Scaling, GRPO post-training, and in-context learning each amplify in-scope abilities, yet none meaningfully improves performance beyond fifth-grade material, indicating the pretraining filter sets the effective capability ceiling.

I played the economic simulator that could 'make a convert out of Karl Marx himself' to see if it could convert me
joshua.wolens@futurenet.com (Joshua Wolens) · PC Gamer · pcgamer.com · 8 min
A writer rediscovers the 1995 business sim Capitalism and recounts the arc from bankrupt detergent-only department store in Jakarta to Guangzhou air-conditioner empire earning $12 million a year. The essay reads the game as a frozen moment of post-Cold War triumphalism, concluding that its worldview is unrepeatable — except perhaps through the sale of air conditioners.
How Photographers Can Turn ‘Bad’ Weather Into Better Landscape Images
Kate Garibaldi · PetaPixel · petapixel.com · 20 min
A landscape photographer with over two decades of field experience explains how storms, fog, rain, and snow can become creative assets rather than obstacles. He details specific methods for reading light, adjusting exposure for snow and fog, using polarizers and neutral-density filters, choosing lenses by conditions, and protecting gear, emphasizing that the goal is to understand what each weather type offers.
‘The kids were right’: 30 years of Pokémon, from school-wide bans to multimillion-dollar trading cards
Patrick Marlborough · Technology | The Guardian · theguardian.com · 6 min
A personal history of Pokémon's 30 years traces its Australian arrival via Cheez TV, the 1999 moral panic that led to school-wide trading-card bans, and the communal play the craze actually required. The essay follows the franchise from $11m in card sales in two months to the $16.5m auction of rare cards, arguing the kids were right: Pokémon's insistence on simple fun made it the world's largest media franchise.

A True Telnet BBS on a Casio Calculator
austinallegro · Hacker News: Front Page · ei3lh.eu · 13 min
A radio amateur documents building a genuine telnet BBS that runs entirely on a Casio VX-4 calculator with just 8KB of RAM, using a Raspberry Pi Zero W only as a network bridge and message archive. The BBS is written in BASIC, enforces one connection at a time at 4800 baud, and limits messages to 60 characters — all to survive the calculator's hardware limits. Includes a full demo of connecting over 5G.
Marvel Tōkon's simple but effective combo trials are an elegant tutorial solution that I wish more fighting games had
PC Gamer · pcgamer.com · 3 min
Marvel Tōkon's Level-Up Missions present players with combo criteria—starting strings, damage thresholds, required moves—instead of scripted inputs, forcing them to design combos themselves. Later missions stack requirements involving meter, assists, and damage scaling, making them genuinely tough. The open-ended approach teaches fundamentals better than scripted tutorials, a feature more fighting games should crib.

The Bre Pettis Collection of Computer Art
bre.art · tyler's Top Finds on Scour Today · bre.art · 2 min
Bre Pettis opens his archive of algorithmic and generative art, begun with works bought from Wolf Lieser in Berlin in 2016 and now documented online for curators and museums. He praises the form's core appeal—intention up front, outcome unknown—and shows the range: plotter drawings, code-generated poems, computer music on vinyl, and sound sculptures.
