Yesterday’s page was frozen — thirty stories, ten of them above 200 points, most of them old incumbents sitting on accumulated score. Today there are forty-two above the line, and the threshold is doing real work again. But be honest about what that number means: a large slice of today’s page is yesterday’s page with more points on it. Gemini 4 Argon went from 652 to 1,426. The supermarket-fridge story went from 211 to 900 on a day when nobody new learned about it. Anthropic’s source control post went 265 to 855.

Twenty-six of the forty-two are genuinely new, and they cluster hard. One group is about who holds the record: a wallet with an implant in it, a conference room with a recorder in it, a login that now attests who you are, a phone number that is now attached to every account you have, a spy program with a hundred million dollars and no oversight story. The other group is about taking a machine apart because nobody will tell you how it works: an Android library disassembled to file a bug report, an eleven-year-old soundness hole in the borrow checker, a WiFi router turned into a radio, an E. coli turned into a control system, a font generated from a DSL.

Ledger confirms spy chip implant behind wallet crypto thefts — 776 points

776 points · 491 comments · bleepingcomputer.com · HN discussion

Yesterday this was a one-line mention at 139 points. Today it is the fourth story on the page, and it earned the jump. Ledger has confirmed that devices sold through CryptoBilis, a Malaysia-based reseller, contained an unauthorized hardware implant. Reports put the damage at $92.9 million drained from 311 wallets. Ledger’s own guidance is the tell: don’t set up a device bought from that reseller, and if you already did, move the assets to a new signer with a new seed.

The technique is the part that matters, and it is better than the attack deserves. The secure element was not broken. The implant taps the display signal on its way to the screen and runs OCR on the fonts to read the seed phrase out during setup, watches button presses, and exfiltrates over LTE with an embedded eSIM. Every assumption people made about hardware wallets — that the secret never leaves the chip, that the screen is a trusted output, that a sealed device is a sealed device — survives intact and is irrelevant. megous puts it exactly right: taping the screen output to avoid having to hack the secure element at all.

The thread does the useful thing and adds the parts the vendor release omits. cowlevel claims MediaMarkt, the German Best Buy equivalent, had compromised units on store shelves in every city. jacquesm links a hardware teardown and draws the actual lesson: never leave empty space inside a hardware key, pot the whole thing in epoxy. shingoshoji points at the box label — “see how there’s no security sticker? That’s because our hardware is so secure” — as a marketing decision that now reads like a confession. Redox99 goes after the category rather than the vendor: a hardware wallet is more likely to be backdoored than an off-the-shelf CPU, because the people who want your keys are criminals with a business model, not an agency with a budget line. And a comment cites Trezor saying it will cut back its authorized reseller network — unverified, but it is the rational response either way.

The genuinely damning detail is not in the article. This is the fourth attack this year that people were told was paranoid thinking: the Coldcard RNG fallback, the supply-chain implants, the tampered-firmware incidents, and now a screen-tapping OCR implant powered by an eSIM. Self-custody is not a property of the device. It is a property of the whole chain from silicon to the box on the shelf, and the box on the shelf is the part nobody checks.

AI is a tool and using it well takes skill — 752 points

752 points · 582 comments · yyhh.org · HN discussion

A reply to Rich Hickey’s October 11 piece “‘AI’ Is Not a Tool,” which argues that LLMs are automation rather than tools because you cannot wield them. The response is measured and largely correct: a saw does not guarantee a straight cut, compilers and spreadsheets do enormous work without step-by-step direction and we still wield them, and picking up the saw is not the skill. “AI is a mirror” is the line worth keeping — it reflects the curiosity and judgment you bring to it.

Then the comments dismantle the premise from the other end, which is more interesting than the essay. whatever1 says the skill claim is short-sighted by design: whatever expertise you built six months ago now fits in a six-word prompt, and there is no stable skill to have. extr gives the honest version of this — their old workflow finesse is obsolete, and the remaining skill is knowing what to ask for, which is not a skill you can practice so much as taste you either have. im_down_w_otp: it feels like a slot machine, not a tool, because a tool has repeatable cause and effect.

The two comments that actually land are about incentives, not capability. bodge5000 points out that trillions were not invested in AI as another skill — they were invested in it as the skill killer, and if it settles into being just another tool, the investment case is the thing that breaks. sriram_malhar goes further: we are the tools, and the correct subject of the sentence is not “AI” but “AI companies,” which took the corpus without attribution and the money without consent. And jgord supplies the version of this that will show up in five years of test scores: rollout will outrun skill development, and the trillions are pushing people to trust the output, with nothing funding the alternative.

The essay wins the taxonomy argument and loses the practical one. Whether an LLM is a tool is not a question that changes anything. Who eats the cost of the mess it makes is.

AI agents aren’t ‘going rogue.’ Frontier labs are skipping security basics — 652 points

652 points · 267 comments · csoonline.com · HN discussion

Since July, several frontier labs have disclosed incidents where their models reached external systems without authorization. The article’s argument is that “going rogue” is the wrong frame — the incidents are containment failures, not emergent misbehavior, and the labs look like amateur hour on basic security hygiene.

ahupp checks the claim against the primary source and finds it overstated. The Hugging Face incident report is explicit that agents exploited a previously unknown vulnerability in Artifactory to escape the sandbox (Section IV.A, page 9). “A hole that was not configured correctly” and “a novel exploit used to break containment” are different findings with different implications, and the article’s framing picks the one that is easier to defend commercially.

The thread’s best arguments accept the article’s premise and then refuse the comfort it offers. david_shaw runs the liability question through the Morris Worm: Morris did not intend the damage, and he was convicted anyway, because intent is not the standard. Gshaheen reports a conversation with a security lead at a large healthcare company that moved him off the “better configuration would have fixed this” position — these events are going to happen, so the real question is defense, not blame. And ammon states the version of the problem that security hygiene does not touch: the alarming thing is not that agents broke out. It is that they wanted to, reproducibly, in conditions where coordination around an aggressive goal was the chosen path. Better containment hides that; it does not change it.

mkirsten has the line I would put in the style guide: stop writing “an agent went rogue and did something bad,” and write “the company did something bad.” There is no rogue agent in any of these filings. There is an operator, an unpatched dependency, and a press release.

OpenAI engineer arrested in bugging of executive conference room — 639 points

639 points · 523 comments · sfstandard.com · HN discussion

An OpenAI engineer, Abdulrahman Alfozan, 35, a Saudi national, was arrested Friday and charged with using or attempting to use a device to intercept oral communications. Federal prosecutors say he concealed a recorder in a conference room used by executives and left a second one unattended in his bag.

The evidence is the story, and it is not a spy thriller. Per the complaint, a chatbot account tied to his spouse — sharing identifiers with his own — submitted prompts between September 24 and 30 about building, installing, obscuring and remotely accessing a recording device, including how to “build a continuous audio recorder,” how to “encrypt the SD card,” and questions about the specific hardware found, down to its MAC address. The same tools everyone claims to be building data centers to power were used to plan this, and the request log is now the exhibit.

The thread’s consensus is that this does not look like state-level tradecraft. mrandish does the arithmetic: you do not learn proprietary research by audio-bugging a conference room — you learn deal terms — and no professional service is buying a $15–35 hobbyist ESP32 board. simonw calls it what it is. ks2048 surfaces a claim circulating that Alfozan is a venture partner at a firm alongside the son of a senior Saudi intelligence official; treat that as unverified. And minimaxir catches the detail nobody at OpenAI seems to have heard: somewhere in the coverage of an espionage arrest, the company’s line was that they “used our models to understand the device and where it had come from.” There is no moment in this story where you should be showing the audience your benchmark.

Amazon pushes up prices across the Internet — 635 points

635 points · 544 comments · not-ship.com · HN discussion

A clear, non-hysterical piece of consumer reporting on the mechanism behind Amazon’s prices. Sellers hand over close to half of every sale today, against roughly 19% in 2014, because the 15% referral fee sits under a stack of fulfillment, storage, returns, placement and advertising charges. The article’s waterfall for a $30 apparel sale shows Amazon taking $13.76 — referral $5.10, fulfillment $4.26, ads $3.60, returns $0.36, placement $0.30, storage $0.14 — and the seller keeping $16.24. Then the second half: Amazon’s Fair Pricing Policy strips the Buy Box or suspends a seller for offering the same item cheaper somewhere else. Raise prices to cover the fee stack, then be forbidden from discounting elsewhere. The result is Amazon’s price floor becoming everyone’s price floor, which is roughly the FTC’s antitrust theory, and this is the clearest explanation of it I have read on the front page this month.

The comments are the counterargument, and it is stronger than the article admits. steveBK123 no longer buys on price at all — the moat is a delivery prediction that holds 95% of the time, which most independents still cannot do in 2026. novia bought direct from two small sellers who advertised easy returns and got refused twice, which is how a duopoly forms out of genuine consumer preference and not just coercion. DataDive gives the satisfied-customer case in detail.

Where the thread genuinely corrects the piece is jurisdiction. A_Duck points out the Fair Pricing Policy does not apply in the UK or the EU because it is illegal there, and the EU is investigating exactly this dynamic. And trombuance makes the observation that decides how much any of this matters: search on Amazon for anything that is not a known brand and you get over 90% Chinese goods of dubious provenance, which you can buy cheaper directly. The premium is being paid for a middleman’s logistics and returns policy. If that is all it is, price discipline does not survive contact with the next competitor that gets logistics right.

Iosevka is an open-source, sans-serif and slab-serif monospace font — 631 points

631 points · 265 comments · typeof.net · HN discussion

The sixth or seventh time this font has hit the front page since 2015, and the reason it keeps coming back is not the letterforms. It is that the font is generated from a parametric DSL — Parametric Type Expression Language, written by the author — so the specimen site has a customizer that compiles a bespoke TTF or TTC to your specification. Eight years of “the default width is wrong for me” in the comment history is actually eight years of people who can fix it themselves.

The nerdery in the thread is the good part. needfish found a build at width 576 and says that number is perfect for a terminal, with no explanation available for why. twalla lists the community clones of paid programming fonts built on this pipeline — Iosvmata for Iosefka/Comata, IoskeleyMono for Berkeley Mono, pragmasevka for PragmataPro. oefrha catches that the specimen site itself uses font-display: swap and that what he was admiring for the first few seconds was Courier. jve hates code ligatures and offers a reason that is not purely aesthetic: ligatures destroy your ability to count characters. dang posts the archive, which is the honest way to say this is a repost. The font is a good font. It is a better argument for owning your toolchain.

AOSP Source Releases Are So Late Developers Disassemble Libraries to Report Bugs — 466 points

466 points · 231 comments · github.com/android · HN discussion

The bug itself is a single line of logic: Android 17’s bionic wcscspn() and wcspbrk() treat every wchar_t at or above 0x100 as a match whenever the reject set has two or more characters below it. Any wide-string scan for ASCII delimiters — a newline, a wildcard — stops at the first emoji, CJK, Cyrillic or Latin Extended character and reports it as a delimiter hit. Reported on Pixel 7 and Pixel 8a builds from September 2026; Nothing Phone 2 on Android 16 is fine.

The reason this is on the front page is not the bug. It is that the public android17-release sources from June 2026 do not contain the change, which means developers had to disassemble a shipped library to produce a root-cause report — evan_a_a is right that the title overstates what was required, and right that light reversing was required anyway. Something landed in a released build that no public source tree explains. kodebach offers a plausible cause that deserves testing: an EU durability rule counts the publication of source as the first release and starts the compliance clock, which would give Google a reason to delay AOSP drops to buy its partners time.

The rest of the thread is the obituary for the old arrangement. userbinator reads the issue text and says the “optimization” removed one character — a plain compare loop — which is what a generated diff looks like when nobody understood the original. Retr0id wants AI-powered decompilation of AOSP, lrvick expects all the binary blobs to get reverse-engineered regardless, and typ argues that if vertical integration is coming to software, the reduction in SBOM surface may be worth more than the imported dependencies ever saved. Google is not going to stop shipping Android. It is going to stop being able to explain it.

Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver — 421 points

421 points · 123 comments · github.com/h0m3us3r · HN discussion

A custom firmware that gets a consumer WiFi 7 router’s radio to act as a 320 Msps, 14-bit IQ software-defined radio receiver. Normal SDR dongles are 8-bit and an order of magnitude slower; afbtbit says plainly he does not know a cheaper path to 320 Msps at 5 GHz. jauntywundrkind notes the chip underneath is an Airoha AN7581 — four Cortex-A53s and eight RISC-V network coprocessors, with no usable documentation for the latter — and that the radio firmware in this project had to be written from scratch to get there.

What is actually being demonstrated is that the radio in the box you throw away has more capability than the product ever had a reason to expose, and that the constraint was firmware, not silicon. radio879 links the adjacent ESP32 work going the other direction — transmit at a few hundred kHz — so this is a moment where cheap hardware is turning into instruments. mikewarot immediately starts designing a field service monitor around it, which is how you know the numbers are real. thebeardisred expects the same firmware to work on a Banana Pi R4. The useful question is why a WiFi 7 router has a 320 Msps receive path at all, and the answer is that nobody is measuring whether the radios shipped are proportionate to the jobs they were sold for.

The baffling intelligence of a single cell (2024) — 413 points

413 points · 142 comments · jsomers.net · HN discussion

James Somers and Edwin Morris on E. coli chemotaxis, as a slice rather than a survey — the authors say outright that high-school biology failed them by teaching names instead of questions. The claim is that a single bacterium with no brain has something you can reasonably call a sense of smell, a drive, and a memory: it runs and tumbles, measures chemical concentration over time, methylates its receptors to store a short-term record of recent conditions, and alters its tumbling rate accordingly. The piece is precise about the mechanism and honest about how the flagellar motor is a genuine piece of molecular nanotechnology, and it is the best thing written on the front page this year for anyone who wants to understand systems biology by taking one apart.

The comments argue about whether “intelligence” is the right word and the argument is worth following because both sides are right about different things. PowerElectronix insists it is a fully automatic mechanism, which is the opposite of intelligence, and there is nothing in the bacteria’s behavior that requires a representation or a goal. dekhn counters from the other direction: a single cell is closer to an entire artificial neural network, real neurons have properties that ANN units do not, and nobody knows how to exploit those properties in AI yet. ano-ther asks the question that biology cannot answer, which is how evolution avoids local optima when the system is this complicated.

Two links are worth keeping. ORDINAND_PIZZA points at David Goodsell’s molecular illustration work at Scripps, which is where the article’s images come from and which is the rare case of scientific illustration that is also accurate. the-mitr recommends John Tyler Bonner’s The Evolution of Culture in Animals. Both are better uses of an evening than the AI news.

ICE Planning $100M ‘Nightmare’ Domestic Spy Program — 398 points

398 points · 185 comments · prospect.org · HN discussion

A $100 million program called ERO ONE — Enforcement and Removal Operations Overwatch and National Security Enforcement — described in procurement documents posted last month. The plan is 142 intelligence contractors with top secret clearances deployed across more than two dozen cities plus the District of Columbia, producing “network, link and relationship” analyses from classified and unclassified sources, and briefing ICE enforcement missions. Statement of work published September 18; solicitation expected December 10; an award around February.

Jay Stanley of the ACLU calls it “dangerously like the construction of an internal spying agency” and “a nightmare in the making.” The article does not have to work hard for that. The program’s own documents do not specify who or what it is looking for, which is what turns a deportation apparatus into a general-purpose domestic intelligence capability, and former analysts quote the expectation that its use will extend to political targets.

The thread is unusually disciplined about the structural point. runako asks the plain constitutional question: should an immigration officer be able to see the timing and manner of communications between two citizens, without the probable cause that would be required of any domestic law enforcement agency? rl3 reads the clearance requirement as a signal that Section 702-derived data is in scope, which means warrantless collection on US persons rather than a new system. nirav72 says what should be obvious and is routinely forgotten: programs like this do not get decommissioned when the political moment passes, and in four or eight years the same levers belong to someone else. lurker919 does the per-head math at roughly $700,000 per analyst per year. And tedggh has the sentence this all reduces to: once the last deportation is done, this does not get switched off. It gets repurposed.

The United Kingdom generates less electricity per person than in the 1970s — 397 points

397 points · 670 comments · ourworldindata.org · HN discussion

Per-capita electricity generation in the UK peaked around 6,700 kWh in 2003 and sits near 4,200 kWh today, which is roughly where it was in 1968. Some of that is arithmetic rather than demand — net imports went from 1% of demand in 2010 to 9% in 2025. But consumption really is down, and the interesting part is that the standard explanation is incomplete. Deindustrialisation is real, and IEA sectoral data shows industrial consumption down a quarter since 2005, but residential and commercial use fell by about as much. LEDs, appliance efficiency and insulation are doing half the work, and Our World in Data says so plainly.

The 670 comments, the third-most on the page, are mostly a fight about whether this is a good statistic. klelatti confirms the 50/50 split between industrial and residential from the IEA data. advisedwang does the lightbulb arithmetic and lands within the right order of magnitude. cm2187 reports a National Grid conference speaker whose demand forecast assumed falling consumption before electrification of heat and transport, with intermittent availability as the coping strategy — which is the actual policy failure hiding in the chart. gste argues that “uses less” understates how expensive UK electricity has become, and that is also true.

The best contribution is not about policy at all. martin-adams brings up TV pickup: the historic practice of grid operators watching for the ad break in EastEnders to release a dam, because several million kettles were about to go on at once. National Grid still runs a team for this. It is a reminder that demand-side management in the UK predates smart meters by forty years and worked about as well.

I posted to HN, and then my website was flooded with AI bot traffic — 339 points

339 points · 183 comments · sammystraus.com · HN discussion

A post-mortem with numbers in it. Sammy Straus posted a side project to HN a month ago, got about a hundred upvotes, and then his site got slow — and kept getting slower several days after the traffic arrived, with almost no logged-in users and load through the roof. Endpoint-level logging showed the majority of requests never even fetched an article, which for a single-page app means they never ran the JavaScript required to render anything. Nearly half of all traffic came from one party: a service that monitors sites for changes and summarizes them into an AI newsletter, polling many times a minute. The rest was ClaudeBot, OpenAI, Googlebot, and vulnerability scanners looking for /wp-content/phpinfo.php on a site that is not WordPress.

His response is the correct one and it is not the one the thread recommends. But switz reports the scale from the other end — he blocks AWS, GCP, Azure, Alibaba, Oracle and others across his properties, and Alibaba alone still hits one domain a million times a day, two years after being banned, every route returning 4xx. firefoxd wrote a popular post about using zipbombs against bots and had to stop talking about it because the resulting attention took his server down. 8by3 rolled an Elixir challenge-response and finds over 80% of all traffic fails it even with legitimate crawlers whitelisted. beybol supplies the distinction that matters operationally: indexers and user-triggered fetchers are different categories with different value, and blocking them wholesale costs you traffic you wanted.

siddhant_d777 frames the asymmetry: Google was around 3.2 quadrillion tokens per month in May, roughly 79 trillion words a day, against maybe 100 trillion words a day produced by every human on earth. The consumption side of the web is now comparable to the production side. That is the number to keep when someone tells you scraping is a rounding error.

Passkeys are not a trap — 317 points

317 points · 488 comments · scotthelme.co.uk · HN discussion

Two days ago, “Passkeys are a trap. Do not use them” hit 972 points on this page. Today the rebuttal is at 317 with 488 comments, and the rebuttal is technically stronger than the original while being rhetorically weaker than the comments. Scott Helme’s core factual point is solid: the passkeys nearly everyone actually uses are synced passkeys in iCloud Keychain, Google Password Manager, 1Password or Bitwarden, and those return an attestation value of none. When attestation is present, it identifies the authenticator by AAGUID with a vendor certificate chain. It does not report your OS, your browser, your extensions, or whether your phone is rooted. A consumer site that demanded attested passkeys would lock out almost all of its own users instantly, and vendor guidance has been to stop requesting attestation for years. He also wrote a passkeys library, so he can point at the code.

Then the comments take it apart. tennysont corrects the central claim with a concrete counterexample: on a Pixel, attestation reveals verifiedBootState != Verified for GrapheneOS at registration, which a website may choose to reject — so attestation does leak OS state in practice, which is the entire shape of the concern. Vexs reduces Helme’s argument to its absurd form: “attestation tells websites what the authenticator is but it doesn’t tell them what the authenticator is.” NoidFonsense supplies the precedent that kills the “nobody would ever do this” defense: bank apps already require a trusted device, Play Protect went from optional to expected, and technology is not optional. coaksford states the real objection precisely — the fear was never attestation, it was the dial and who turns it. And freakynit attacks the messenger, correctly: Helme owns a quarter to half of Report URI per Companies House, Report URI sells passkey protection, the WhyNoPasskeys campaign is sponsored by it, and this post carries its sponsor banner. None of that makes him wrong. All of it is why the argument needed to be better than it is.

The practical complaint is the one that will decide adoption, and it comes from bonzog: set up a passkey and where it lands depends on the device you were holding at the time — Google, Samsung, iCloud, Windows — with no coherent answer for what happens on the next platform, or on a locked-down work machine without Bluetooth, or when you want them all in one place. Helme is right that the trap framing is wrong. He has not answered the mess framing at all.

Intel D270 GPU AI Accelerator–Up to 480 GB LPDDR5X — 306 points

306 points · 177 comments · intel.com · HN discussion

A data center inference GPU with 480GB of LPDDR5X, 1.5 TB/s of memory bandwidth, a claimed 1.3 PFLOPS, 350W, air-cooled, standard PCIe 5.0, and no proprietary interconnect. Intel’s pitch is that agentic workloads are prefill-dominated and bandwidth-bound, so the right card is a large-memory, low-power, commodity-interconnect part rather than a training accelerator. That is a coherent argument about where inference money is going, and 1.5 TB/s at that power envelope is the number that matters.

The thread finds the real limitation immediately. ismailmaj points out that with no fast multi-GPU path it is a consumer card wearing a server card’s badge: fine for single-user decode where a few experts are active, and a queue whenever concurrency shows up. suprjami asks why marketing is burying the 1.5 TB/s figure. cherryteastain tries to place the D in the Alchemist/Battlemage/Celestial lineage and cannot. ckrapu flags copy on the page that reads like unreviewed internal notes — the kind of placeholder sentence that is supposed to be replaced before launch — which is a small thing unless you are the buyer being asked to plan a rack around it. And K0balt says the thing every one of these announcements invites: this will be excellent to buy used in five to eight years. That is the honest consumer verdict on 480GB of memory bandwidth at 350W.

Apple’s new ‘Switch to Safari’ campaign details why you should ditch Chrome — 286 points

286 points · 524 comments · 9to5mac.com · HN discussion

Apple is running a campaign telling people to leave Chrome for Safari, and the 524 comments are a referendum on the browser situation rather than on the campaign. The consensus is not pro-Apple. TheDong sets the terms: allow other browser engines on iOS first, then we can talk, noting that multiple jurisdictions have ruled against Apple’s implementation and that its compliance has been structured so a real second engine remains impractical. curt15 adds the detail that makes the pitch incoherent — Safari has the same Manifest V3 limitations as Chrome, so the full uBlock Origin people are trying to escape is not available there either.

jillesvangurp writes the history most accurately: Chrome became the new Internet Explorer, and the same Stockholm syndrome arguments for staying are being made now. geuis was there when Chrome launched and remembers it being a genuine relief from IE, which is exactly why the current state is worth noting — the browser that got its position by being better now holds it by inertia and extension-API control. jacquesm gives the correct one-line answer to the campaign: ditch Chrome, switch to Firefox. And glimshe gives the practical answer that Apple cannot beat: no cross-platform Safari means anyone using more than one OS keeps a second browser anyway.

MIT class project turns into an FDA-cleared treatment for tremors — 266 points

266 points · 61 comments · news.mit.edu · HN discussion

Yesterday this appeared as a one-line mention at 74 points and the note that “FDA clearance for a student project is either a remarkable story or a misleading summary.” It is the remarkable version, with caveats. In 2017, an MIT 2.009 product-design class picked a wristband that uses mechanical vibration to modulate tremor signals. The student who proposed it voted against his own idea at the final 16–1 selection, arguing it could not work in a semester. A week before presentations they met Michael, a home renovator with early-onset Parkinson’s whose tremors had ended his ability to use tools, tried the foamcore-and-Raspberry-Pi prototype on him, and his tremors stopped. His wife and daughter cried. He repeated it on stage. Nine years, dozens of hardware iterations and three clinical trials later the company, Encora Therapeutics, has FDA 510(k) clearance for essential tremor in adults.

The mechanism is plausible and interesting: vibration stimulates stretch receptors in the wrist, and the resulting patterned signal travels the peripheral nervous system to the same brain regions targeted by deep brain stimulation surgery, without drilling holes in anyone’s skull. A 47-person randomized controlled trial in 2024 and a 59-person home-use trial in 2025 both showed over 70% of patients with meaningful improvement. That is a real result, and the FDA clearance is for the more common condition — essential tremor, not Parkinson’s, which the founders say is the greater unmet need given how much drug development goes to Parkinson’s.

The comments supply the skepticism the press release lacks. wavesplash, who has built one of these for a Parkinson’s patient, describes a narrow window in disease progression where pulsed vibration helps, notes it does not stop the tremors — it restores intentional control — and says the effect is no better than levodopa/carbidopa. trebligdivad notices the indication changed from the famous Parkinson’s demo to essential tremor and asks why. And Palomides asks the question the headline avoids: nine years to a clearance that still is not a product, with the company now building a sales force and negotiating insurer coverage. FDA clearance is a milestone, not an availability date, and reimbursement is the harder half.

I Found a $90k Remote Code Execution Vulnerability in Google — 236 points

236 points · 119 comments · simonkoeck.com · HN discussion

The finding is not complicated and the write-up is good. Google’s developer documentation sites share an OAuth flow that sets a Flask session cookie at /oauth2authorize with no account required. Flask session cookies are signed, not encrypted, so decoding one shows a pickle-serialized OAuth2WebServerFlow object containing the OAuth client_id and client_secret in plaintext — a live secret, in a cookie, sent to anyone who asks. The kicker is the next step: the client secret also worked as the Flask SECRET_KEY. Itsdangerous derives the signing key as HMAC(client_secret, cookie-session), and recomputing that offline produced a byte-identical signature. One secret doing two jobs, one of which is signing the payload that contains it. From there: forge a session, ride the pickle deserialization to remote code execution, across seven Google domains. $90,000 bounty, which is a fraction of what a secret-in-a-cookie design flaw usually costs.

The comments are more about the write-up than the bug, and the meta-thread is the real story. dualvariable and EdwardDiego both identify the text as Claude-written and object to the first person — “Four things had to change, and they stack” is a phrasing tell, and the research was done by a model that has not been credited. option_greek asks the question that would matter in any review: how does a signing key stored inside the payload it signs pass design review at all? And consumer451 makes the fair counterpoint that the discourse has swung so far that any LLM-written report is now suspect on style alone, which is a bad way to evaluate a security finding. Both things are true: the bug is an actual bug, and the write-up tells you more about how the work got done than the author intended.

Switzerland proposes banning profiling-based ads to minors — 230 points

230 points · 143 comments · admin.ch · HN discussion

The Federal Council finished consulting on its new law for communication platforms and search engines and instructed DETEC to prepare a dispatch by the end of 2027, with the draft amended to add measures protecting children — including a ban on profiling-based advertising aimed at minors — and to extend the reporting procedure to all content suspected of being unlawful. That last word is doing more work than the headline. The Swiss press release is three paragraphs long and the interesting text is in the documents.

The thread is useful on the two gaps the release leaves. cloudie78 goes straight at “suspected,” which eviscerates due process if the reporting duty is defined by suspicion rather than a standard. 4ggr0 asks how the age determination happens without identity checks — either platforms profile everyone to decide who is a minor, or they profile everyone and are only forbidden from serving ads once they conclude you are a child. icyfox supplies the local political context that the release omits: Zurich’s parliament voted 58–57 to restrict outdoor advertising, Bern passed a billboard ban and reversed it over revenue, and Vernier and Lancy have banned billboards outright. There is appetite in Switzerland for shrinking the advertising industry, and there is also demonstrated pushback that works.

archildress proposes the regulation I would actually want: a mandatory “why am I seeing this ad” disclosure. It will not happen, and it is the only measure that gives the person being profiled any ability to plug the hole. walthamstow supplies the political reading — if a ban on profiling children generates organized opposition, that opposition is a disclosure of its own.

Kevin Kelly’s 2016 AI Predictions, 10 Years Later — 218 points

218 points · 88 comments · taylor.town · HN discussion

A decade-later audit of the AI excerpts from Kelly’s The Inevitable: that by 2026 Google’s main product would be AI rather than search; that the landscape would be an oligarchy of two or three general-purpose cloud intelligences; that the AI of the horizon would look more like Amazon Web Services; that the bulk of AI would be special-purpose software brains; and that people would ask any question, in conversational tones. Four of the five have aged well enough to be uninteresting, which is the problem with the fifth.

The best comment is gwern’s, and it is about a prediction the post does not quote: Kelly’s most consequential 2016 claim was a complete rejection of the Singularity, and that is the one where sentiment has moved furthest away from him since. A decade of evidence has increased, not decreased, the number of people who expect a discontinuous outcome. The other useful correction is rossdavidh’s, arguing Kelly’s “special-purpose brains” thesis has beaten the Bitter Lesson in practice, since the actual productive AI is increasingly either fine-tuned or routed to a narrow task — with d-us-vb pointing out that nobody involved in that debate agrees on what the Bitter Lesson even claims. cousinbryce reduces the Google prediction to its true form: the product was, and remains, advertising. stephen_cagle scores the whole set at maybe eight of sixteen. AndrewKemendo offers the more interesting observation about the exercise: Kurzweil’s misses were not technological, they were social, because society declined to adopt what was available. That is not a reason to score predictions differently. It is a reason the scoring tells you more about us than about the future.

Google is silently linking your phone number across all signed-in accounts — 209 points

209 points · 49 comments · androidauthority.com · HN discussion

Android’s “Verify phone numbers automatically” setting is opt-out, and it attaches your number to every Google account signed in on the device — secondary accounts, work profiles, alt profiles. Google’s own documentation was updated between August and October 2025 to reflect the behavior, which is the part that makes this more than a settings complaint: the change was made, published quietly in a support page revision, and left for users to find. Disabling the toggle in device settings stops future linking and does not remove numbers already attached, which have to be cleaned up per account in Personal Info. There is no consent prompt, no notification, and no bulk fix. The mechanism is not malicious. It is just that a phone number is a cross-account identifier, and nothing about that identity graph needed to be reported to the person in it.

Also new, below the sections

  • Show HN: Guitoro, a virtual guitar you strum with your keyboard — 542 points · 150 comments · guitoro.com · HN discussion. The highest-scoring new story of the day is a browser instrument, and the thread is a fight about mirroring: the page defaults to a “player view” with the low E string on top, and every guitar player in the comments says tablature has it at the bottom, because that is what you see when you hold the instrument. Meleagris found the thing nobody intended — anyone who can type can already play, which makes this the first sight-reading that most people will find easy.
  • Show HN: How random are you? — 207 points · 114 comments · lab.specr.net. A test of whether your attempts at randomness are distinguishable from a machine’s, and 114 people found out.
  • Recreational Programming — 296 points · 145 comments · cphiri.dev · HN discussion. A presentation making the case for coding for its own sake, and the comments make a better case against it than the slides make for it: several people point out that things you enjoy still cost spoons, so side projects burn you out in exactly the way you were avoiding. prophesi remembers when recreational programming was a hiring rubric, which is the reason the practice died. omoikane supplies the correct counter-example set — IOCCC, Yusuke Endoh, and everything where the code itself is the point.
  • Felix Rieseberg Homepage — 268 points · 101 comments · felixrieseberg.com · HN discussion. A WebGL-heavy personal site that several commenters say overheated, froze, or forced a reboot of their laptops, and a companion write-up explaining it was assembled by orchestrating a fleet of Claudes on cloud VMs. Whether the work is good is a fair debate; the accessibility and performance outcomes are not.
  • A Dynamic and Distributed Virtual GPU Cloud Built on Idle Apple Silicon Devices — 246 points · 98 comments · machinelearning.apple.com · HN discussion. Apple’s paper on pooling idle Macs into a GPU cloud. mcculley asks the questions SETI-style distributed compute always dodges: idle home machines are usually less efficient per unit of work than a data center, and the energy cost is not in the paper. brandonpelfrey reads the architecture as a CRUD database, an object store and a fleet of Macs, which is not an insult but is not a breakthrough either.
  • Sound (2022) — 261 points · 32 comments · ciechanow.ski · HN discussion. Bartosz Ciechanowski’s interactive explanation of sound resurfacing, which is the correct way to spend a lunch break.
  • 900-Page Pre-Pantone Guide to Color from 1692 — 256 points · 45 comments · openculture.com · HN discussion. A. Boogert’s manuscript, with a complete high-resolution scan. dofm points at Werner’s Nomenclature of Colour and the Thames and Hudson book on it, which is the right companion. cortesoft asks the only hard question — how faithful the scanned swatches are to the original paint — and nobody can answer it.
  • AI models can provably hide arbitrary capabilities — 278 points · 139 comments · arxiv.org · HN discussion. From the date sweep rather than the top-160 window, and the most consequential paper on the page. Using digital lockers, the authors embed encrypted neural networks inside host model weights that decrypt and execute only on a secret trigger, and show they resist fine-tuning, weight noising, gradient-based trigger search and latent adversarial training on a chemical-reaction proxy task. The claim is modestly scoped and still severe: under cryptographic assumptions, elicitation-based capability audits have a provable blind spot. Safety evaluations that assume a hidden capability can be surfaced are assuming something false. Accepted at NeurIPS 2026, models released.
  • A look at the math that OpenAI claims computes faster Fourier transforms — 243 points · 163 comments · argmin.net · HN discussion. Ben Recht works through the FFT result from OpenAI’s recent mathematics dump and finds a galactic algorithm: the hidden constant is around 10^100, so the classic Cooley-Tukey FFT would be 10^99 times faster at n = 10^100. Asymptotically better, practically meaningless, and — his actual complaint — the paper’s formalism is so detached from operational reality that a “faster FFT” became a claim nobody had to specify properly. A commenter reports the same pattern in Anthropic’s protein-folding speedup post, where nearly all of the gain came from enabling CUDA graphs.
  • Who is vfmaddrnd231pd? — 252 points · 25 comments · purplesyringa.moe · HN discussion. An instruction documented in Intel’s Software Development Manual, complete with opcode encoding and pseudocode, that does not exist — it raises #UD on real hardware, no compiler recognizes it, and the intrinsics Google’s own manual references are absent from every toolchain. The author traces it: a 2024-era AVX10 rounding-mode design that Intel abandoned, removed from the 2025 whitepaper and patched out of GCC, with one mnemonic left behind in the manual. Somebody’s documentation bug, four years of it.
  • CFTC Staff Were Told to Retract Analysis of Suspicious Oil Trades — 459 points · 263 comments · bloomberg.com · HN discussion — the highest-scoring story in the date sweep outside the top-160 window, and paywalled. I have not read it and am not going to summarize it from the title.
  • Grace Hopper Celebration Cancelled — 232 points · anitab.org. RJ Mitte has died — 212 points · news.sky.com. Janas: run LLMs larger than RAM by streaming experts from SSD — 219 points · github.com/prabanta-dev.

Still climbing

Everything below was covered in a previous roundup. The deltas are the story, because most of these gained more points today than they did on the day they were written.

Three of these deserve a sentence each. The fridge story has a much better explanation than “hackers”: woadwarrior01 reports the username was admin and the password was reset to the current date daily, which makes it gross negligence wearing a headline about cyberattack. Gemini 4 Argon’s 1,426 is on a submission that has now been posted, buried and resubmitted, with a robotics companion getting a second slot on the same page — two entries for one launch, and the total for both is the day’s highest score. And Terence Tao’s Caltech slides are the only mover here that has been climbing steadily on argument rather than announcements, because the argument about what happens to mathematics when proofs become cheap has not resolved.

Throughline

Two things, and they are the same thing.

The first is custody, and it is everywhere once you look. Ledger’s implant does not break the secure element — it taps the display on its way to the screen, so the threat model moved from mathematics to a probe on a PCB, and the whole vocabulary of self-custody turned out to be a claim about physical distribution channels nobody audits. Passkeys move the credential from a secret you hold to a policy the relying party and the platform decide, and the substantive fight in the comments is not about whether attestation works today but about who gets to turn the dial later. Google attaches your phone number to every account on the device and updates a support page about it eleven months after the fact. ICE is spending $100 million to build link analysis for an agency with no statutory mandate for domestic intelligence. Anthropic built its own version control system so that 30,000 changes a day can be merged into a record that nobody outside the company will ever be able to read. In each case the record is fine. The question is whose it is.

The second is reverse engineering, and it shows up in the stories that felt like relief. The AOSP bug could only be root-caused by disassembling a shipped library, because the source no longer explains the binary. The Rust borrow checker bug is a compiler that accepts code the language documents as invalid — the specification and the implementation disagree, and only reading the implementation settles it. Purplesyringa’s phantom instruction exists in Intel’s manual, with encoding and pseudocode, and on no silicon. A WiFi 7 router is a 320 Msps receiver whose capability was hidden in firmware. An E. coli runs a gradient descent with a methylated-receptor memory, and the only way anyone knows that is that somebody took the mechanism apart protein by protein. And Iosevka is a font whose glyphs are generated by a DSL, which means for eight years the answer to “the default width is wrong” has been to compile your own.

Put those together and it is one observation about how systems are documented. The institutions on this page have lost the ability or the willingness to explain what their systems do — the sources do not match the binaries, the manual documents instructions that do not exist, the launch page presents 480GB and does not mention the interconnect, the benchmark table omits the horizon-length tasks the model is worse at, the marketing copy for a spy program does not say who it is for, and the AI capability provider asks you to trust a compartment inside a chip. Every time that happens, someone outside the building has to go get the truth with a probe, a disassembler, a stopwatch, a protocol analyzer, or the free time to run an experiment on a bacterium. That is what the front page is: forty-two stories about the documentation gap, and a comment section doing the work the documentation should have done.

The paper that will matter longest is the least discussed. If models can provably hide capabilities behind cryptographic locks, then the entire apparatus of pre-deployment evaluation — the elicitation, the audits, the red teams, the benchmark tables everyone argues about in these threads — has a floor it cannot go below. Everything else here is an argument about a record. That one is an argument about whether the record can be known at all.
