John Hartnup got tired of the identical pastel village-fayre posters and just named styles at ChatGPT: Bauhaus, Japanese minimal, Memphis, Designers Republic, a photocopied 1980 punk zine, a 90s drum-and-bass flyer. They still look generated, but they don't all look like the same tombola. 1,344 points and 758 comments because HN would rather fight about taste and Fiverr than admit the prompt was 'say Bauhaus.'

OONI Probe is the Tor-adjacent install that tests whether websites, WhatsApp, Telegram, and circumvention tools actually reach you, then dumps the result into the public censorship corpus in near-real-time.

Slop Sense is a 60-second swipe game: real photo or AI, ten seconds per image, streak bonuses, minus 100 if you miss.

The DS/PC-only Dream Devourer sits at 32,000 HP, a few hundred under the signed 16-bit cap. Phase two absorbs elemental magic, so a strong Dual Tech heals it past 32,767, the counter wraps negative, and the boss is dead. Thirty-one points of people remembering the elixir glitch, then arguing about Chrono Cross; I opened it because winning by overflowing HP is still the funniest kind of systems bug.

Bryan Hance's Xerox-to-HTML dump of cryptic full-page ads in the Arizona Daily Wildcat — mixed languages, pandiagonal magic squares, biblical junk, math — paid for since 1981 and still landing; the site's last note is June 22, 2026. He walked into it as a UA freshman in 1995, the authors emailed in '99 to insist it isn't a game and it has a cause, and the downtown Tucson safe-deposit box is still a rumor. Twenty-six points because a forty-five-year newspaper puzzle that refuses to die is the hobby post.

Stanford's Loh lab in Nature Neuroscience: gastrulation makes two lineage-locked neural ectoderms — Otx2 cells become forebrain and midbrain, Gbx2 cells become hindbrain — with chromatin that never overlaps, which is why people spent decades failing to coax a generic neuron into brainstem. They finally grew human rhombomere 5/6 motor neurons in a dish, the cells ALS and SMA actually kill; the same Otx/Gbx split shows up in chick, zebrafish, and acorn worms, about 550 million years. The PR says two organs; the paper says composite organ. Six hundred points because rewriting the word brain still works.

Until 1846, English coroners could seize a chattel that killed someone — deodand, from deo dandum, paid to the Crown and sometimes the family. A hotel floor collapse was five shillings of timber; a church bell didn't count because it was real estate; a locomotive would have been the whole train, so Parliament killed the rule to spare the railways and left uninsured passengers and railway workers with nothing. JSTOR Daily is here for the cart-pole hair-splitting, then waves at civil forfeiture.

Old-web shrine for Gerry and Sylvia Anderson's 1970 live-action show: 26 episodes, SHADO buried under a London film studio, interceptors off Moonbase, Skydiver that's a sub plus a fighter, aliens harvesting organs in what was then the 1980s. Space: 1999 started as the sequel; Julian Gollop later bought a UFO tape for the worldwide-org idea that became X-COM. Forty-seven points of purple Moonbase wigs and whiskey buttons, which is a perfectly reasonable Sunday.

Camera attestation dies the second you JPEG. Prior ZK edit-history papers skipped lossy compression; this IACR preprint compiles Python image ops through PicoZK into an LPZK circuit that proves DCT, quantization, blur, and redaction from a secret committed original. First JPEG-in-ZK, and it shows: a ~2MP file is six minutes of circuit compile plus five minutes of interactive proof and 30GB of prover traffic, which they admit is an org-to-org tool, not a tweet. Forty-nine points because C2PA still trusts the editor.

Cua open-sourced CUA-S1-FORMS: a 706k-parameter, 2.8 MB option scorer that, given a form field and extracted document values, returns fill / check / click / skip in one pass instead of looping a frontier LLM. No invented text, no screenshots; Cua Driver just runs the ordered actions. Fifty-nine points because the Jev System One idea is leaking into computer-use, not because a 2.8 MB form filler moves the stack.

Jimmy Maher's Digital Antiquarian tracks how Lemmings went from 1991 zeitgeist to a dead franchise: DMA wanted hardcore, Psygnosis wanted Sesame Street faces, then DMA checked out to build Grand Theft Auto and shipped a turkey.

Nature exclusive: Mamdouh Eldamaty's team stacked interior GPR, 1,200+ microgravity readings over 35 m², and old resistivity to argue there's a hidden complex behind Tutankhamun's KV62 — a ~2 m rubble-filled corridor behind the north wall, plus rectilinear low-density blobs.

GPT-6 Astra decoded a leftover WWI ADFGVX intercept from the Scienceblogs.de unsolved list by trying TRUPPENVERSCHIEBUNG — a published German key that wasn't supposed to start until December 9, on a message dated November 27. The plaintext is an English cruiser at Sevastopol on the 24th and an allied squadron on the 26th, which matches HMS Canterbury's logs.

JWST's little red dots — one-pixel, galaxy-bright, first-billion-years — still don't sit still: too quiet and X-ray-dark for textbook quasars, too bright to be baby galaxies. Two 2025 spectra with a proper Balmer break got de Graaff and Naidu calling them black hole stars, a hydrogen ball past Pluto's orbit with a black hole as the furnace (Begelman's old quasi-star, back from 2006); Maiolino says you're just looking at a dusty doughnut edge-on. I'm here for the fight — if the August census that they vanish by 2–3 Gyr holds, that's how supermassive black holes get born.

A Stripe checkout that sells private, transferable contracts for one yellow onion, $3–12, up to six months out — they cite 7 U.S.C. § 13-1, which only bans onion futures on a board of trade, and insist they aren't one. Delivery in SF, Toronto, Seattle, Chicago; no refunds even if the onion never shows; you pass the contract by handing someone a key. 369 points because HN will always click the onion-futures ban loophole.

Custom 32-bit VHDL CPU, bit-addressable, TEA-encrypted words scattered through a 1GB image, synthesized to an obfuscated gate-level netlist — sat on crackmes.one for a year while humans and the usual models bounced. GPT-6 did it in 20–30 minutes on SRE-Bench by differential-analyzing the lazy register-state XOR the author left in so the gate count wouldn't explode, then replaying the netlist and dumping memory; he says that's a side-channel, not a full reverse. Seven points, two comments, but a homemade CPU plus a model that found the cheat is why I opened it.

tptacek's method: you write the draft, then two hard rules — you may not use a single word the model suggests, even the ones that sound better, and you forbid it from cheering because it will tell you the first draft is gold. After that it's a copyeditor that never gets tired of buried verbs and the two paragraphs that should swap; he points at Style: Lessons in Clarity and Grace and a homemade HTMX workshop. 621 points, 373 comments — the writing-with-LLMs discourse at its usual altitude.

Grunewald's plea: almost never let the model type the sentences — writing is the thinking, and the slop is vague-and-wrong in ways you only catch if you already knew the subject (he walks a Claude graf on chip smuggling and finds applause lights).

A new Floppy Emu batch from a different contract manufacturer came back haunted: ATMEGA1284 boards that wouldn't boot, jumped into random firmware, or ran in slow motion. Power and programming checked out; flipping the chip to its internal 8 MHz oscillator brought them up at 40% speed and pointed at the 20 MHz Pierce crystal — they'd substituted an ECS part for the usual NDK (same 8 pF load, some packages with a burned gray dot). Swapping the old crystal back fixed five of seven; the 18 pF load caps were a red herring.

Lemire ran the base M2→M5 chips: Geekbench 6 single-core is about +52% in three years, multi +83%. Most of the single-core jump is P-cores going 3.5→4.6 GHz and decode widening 8→10; the extra E-cores and 100→154 GB/s of LPDDR5X are the multicore story. SIMD barely moved (still four 128-bit units versus Zen 5's 512-bit), SME showed up on M4, and M6 just added two 'super' cores. Yearly silicon recap, but it's the numbers, not the keynote.
