  13. America Could Wipe Out Mosquito-Borne Diseases—If Regulators Let It — ▲ 238 · 💬 180 · 🔗 worksinprogress.co
    Dengue cases in the US jumped 360% in 2024, and malaria returned in 2023. The technology to eliminate disease-carrying mosquitoes exists: Oxitec's gene-edited Aedes cut populations by up to 95% in field trials, and Wolbachia-infected mosquitoes reduced dengue by 70% in Singapore. But Oxitec's application spent 15 years bouncing between the USDA, FDA, and EPA, and its commercial registration is still pending. The 1986 Coordinated Framework is the bottleneck.

    A 28-year-old lab worker at Siberia's anti-plague institute died after falling ill at work, and US Secretary of State Marco Rubio says Washington is monitoring the case closely. Russia's health watchdog calls it pneumonia of unknown origin, but quarantine measures have locked down hospitals in Irkutsk and over 60 institute staff remain isolated.
  16. Apple's Security Update Left Me Hacked—and My AI Agent Saved Me — ▲ 195 · 💬 177 · 🔗 stratechery.com
    A macOS screen-sharing vulnerability (CVE-2026-65400) let attackers plant a Monero miner on my always-on Mac Mini. My Claude agent detected the intrusion, stopped executing commands, and helped remove the malware. But Apple's TCC permission prompts and misleading security-update labeling made the machine harder to secure, while Apple's new Full Disk Access restrictions threaten the agent workflows that saved me.
  17. AI agents uncover a room-temperature magnetic semiconductor hiding in a 1999 material — ▲ 178 · 💬 136 · 🔗 vals.ai
    A team of AI agents and a researcher used density functional theory to hunt for Luttinger-compensated magnets—antiferromagnets with zero net magnetism but spin-sorted electrons. They designed YBaMnFeO₅, a semiconductor with a 2.35 eV gap and spin windows of 1.0 eV and 1.4 eV, but its atoms scramble at synthesis temperatures. More promising: KV[Cr(CN)₆], first made in 1999, which calculations show has a 2.1 eV gap, spin windows of 2.6 eV and 1.6 eV, and magnetic order up to 376 K. Its spin sorting had been overlooked for decades.

  19. Plain Text Is Still One of the Best Technologies We Have — ▲ 172 · 💬 88 · 🔗 deadparrotbbs.com
    Plain text endures because it's simple, portable, and inspectable — no proprietary format, no required app. It's the backbone of code, configs, and logs, and tools like grep and sed have handled it for decades. Markdown adds formatting while keeping the source readable. The author argues that boring, durable formats beat feature-rich ones that lock your data into a service.
  20. Jev's decision models don't beat LLM-as-a-judge or traditional classifiers — ▲ 153 · 💬 70 · 🔗 developers.redhat.com
    Red Hat benchmarked nine guardrails across four paradigms on prompt injection and content safety. Jev, a zero-shot decision model, ranked fourth in both tasks, trailing a 200M-parameter pretrained classifier and a 35B LLM-as-a-judge. While Jev offers schema guarantees and speed, it doesn't outperform established methods, and open-source alternatives like Laya and DiffusionGemma match or exceed it.
  21. Nobel Prize in Medicine 2026 awarded for optogenetics, the light switch that controls brain cells — ▲ 134 · 💬 1 · 🔗 nobelprize.org
    The 2026 Nobel Prize in Physiology or Medicine goes jointly to Karl Deisseroth, Peter Hegemann, and Georg Nagel for optogenetics. Hegemann and Nagel discovered channelrhodopsin, a light-gated ion channel, in the single-celled alga Chlamydomonas; Deisseroth turned it into a switch that fires nerve cells with blue light, first in rat neurons in 2005 and then in living mice. The method now lets researchers map the neural circuits behind memory, feeling, and behavior, and is being tested to restore sight.
  22. A Trick for Type-Safe Generic Data Structures in C — ▲ 133 · 💬 103 · 🔗 danielchasehooper.com
    Daniel Chase Hooper shows how to make generic data structures in C type-safe using a union with a payload member. The compiler catches type mismatches when you pass the wrong type to a macro like list_prepend, and the payload member takes no memory. He also covers inline storage with flexible array members and using __typeof__ for type-safe returns.
  23. The independent individual has always been imaginary — ▲ 133 · 💬 102 · 🔗 onlys.ky
    Angie Dixon writes from a single room engineered around her body — adjustable bed, trapeze bar, grabbers, a grip on her keyboard — and argues that this is not dependence but a functioning life. Our culture defines independence as doing everything alone, a standard almost no one meets; the difference is only whose assistance stays visible. Independence means having enough support to direct your own life.
  24. Why foldl and foldr Are Not About Left and Right — ▲ 130 · 💬 29 · 🔗 blog.haskell.org
    Alexis King's classic explanation clarifies that foldl and foldr both traverse lists left to right; the difference is associativity. In lazy languages, foldl builds huge thunks and should be replaced by foldl', while foldr can stream and even handle infinite lists when the reducing function is lazy in its second argument. The rule: use foldl' for strict accumulators, foldr for lazy ones, and never foldl or foldr'.
  25. Building a GTK Todo App in Haskell with the Elm Architecture — ▲ 126 · 💬 29 · 🔗 floreal.tech
    This tutorial walks intermediate Haskellers through creating a todo-list application using Haskell, GTK 4, and the Adwaita library via haskell-gi.

  29. I designed a lamp for my espresso bar and 3D printed it in one piece — ▲ 116 · 💬 61 · 🔗 arslan.io
    A personal tour of a designer lamp collection, from the Artemide Tolomeo and Richard Sapper's Tizio to Isamu Noguchi's Akari series. The author explains the history and design details of each piece, admits they aren't cheap, and shares how he 3D-printed custom adapters for some—including his own Block Lamp design.
  30. A 40ms Go GC pause caused by swap — ▲ 107 · 💬 129 · 🔗 frn.sh
    I ran swap in production to absorb memory spikes, but it backfired: Go's garbage collector reads its metadata in a stop-the-world pause, and that metadata can end up in swap. On a Hetzner box with NVMe, the worst pause hit 40ms, with 39ms spent on 228 page faults inside GC bookkeeping. The median pause is only 51 microseconds, so this is 800 times worse. I also saw message building jump from 3-5ms to 105ms on NVMe and 903ms on network volume. Go 1.26's Green Tea GC doesn't change this.
  31. ArtCraft builds seven open-source creative apps in pure Rust — ▲ 106 · 💬 153 · 🔗 getartcraft.com
    ArtCraft is developing seven open-source, Adobe-compatible creative applications—PhotoCraft, VectorCraft, FilmCraft, LightCraft, PrintCraft, EffectCraft, and DesignCraft—all written from scratch in Rust.

The apps prioritize familiar professional workflows, local file processing, and agent-ready automation via CLI, JSON, or MCP server. Early alphas are available for PhotoCraft and PrintCraft.
  32. Tech Worker Embarrassed by Industry's Failure to Make Digital Life Usable — ▲ 106 · 💬 125 · 🔗 blog.jim-nielsen.com
    Ben Thompson said on a recent episode of Dithering that he felt embarrassed as a tech worker while helping his mom manage her digital life, because everything was too hard and convoluted. That same evening, Jim Nielsen received a text from a family member ranting about the modern web: "Dude. I hate the modern web. I hate. Website. S. Using websites. Trying to do things quickly and efficiently. What a buggy mess." Nielsen hears this often from non-tech family and friends, and as their connection to tech, he too is embarrassed by the industry's collective failure.
  33. We Won't Stop Using Plastics, and That's the Real Climate Problem — ▲ 102 · 💬 63 · 🔗 onlinelibrary.wiley.com
    A Hacker News commenter argues that demand is infinite and driven by desire, so blaming business greed for plastic use misses the point. People choose convenience—driving to the store, living in houses—over environmental efficiency. These small choices, plus polymers needed for insulation and cabling, mean individual action won't meet CO2 goals and plastics aren't going away.
  34. Borland Turbo BASIC: The Compiler That Broke the 64KB Barrier — ▲ 102 · 💬 54 · 🔗 dosdays.co.uk
    Borland Turbo BASIC began as BASIC/Z, the first interactive compiler for CP/M, written by Robert Zale. Borland bought it in 1987 and released it for MS-DOS, selling an estimated 80,000 copies in its first 10 weeks. Unlike GWBASIC's 64KB limit, it produced executables of any size and offered an integrated development environment. After Borland discontinued it, Zale reacquired the rights and continued it as PowerBASIC.

  36. UCEPROTECT blacklists innocent sites by ASN, then charges $30/month to whitelist them — ▲ 99 · 💬 59
    A site owner discovered their IP was blocked by Orange's security filters because UCEPROTECT Level 3 lists all of ASN 14061 (DigitalOcean) by reputation, not individual wrongdoing. Other major hosting providers' ASNs are also listed. UCEPROTECT offers whitelisting for about $30/month or $108/year, which the author calls extortion after 20 years in the industry.
  37. Mars's Chaos Terrain: A Landscape Unlike Any on Earth — ▲ 98 · 💬 25 · 🔗 en.wikipedia.org
    Mars has vast regions of chaotic terrain, where jumbled blocks and deep valleys suggest catastrophic floods. Scientists estimate these channels formed 2.0 to 3.8 billion years ago, likely when underground water burst forth in massive releases. Theories range from sudden melting of ground ice to gradual sublimation, and the terrain may still harbor water ice today.
  38. The SEC Now Needs Just One Person to Act — ▲ 94 · 💬 53 · 🔗 ft.com
    The SEC's quorum requirement has effectively collapsed: with enough commissioners recused or absent, a single official can now approve enforcement actions and rule changes that once required a bipartisan majority. The shift hands enormous unilateral power to whoever remains, raising questions about accountability, due process, and whether the agency's guardrails still function.
  39. GitHub Actions Hit by Runner Assignment Delays — ▲ 92 · 💬 63 · 🔗 githubstatus.com
    GitHub is investigating degraded performance in Actions, with delays in assigning GitHub-hosted runners affecting workflow start times across multiple configurations. The incident, first reported on October 5, 2026, remains under investigation as teams work to mitigate the impact.

  43. ChatGPT Is Forging New Yorker Cartoonists' Signatures on AI-Generated Cartoons — ▲ 82 · 💬 10 · 🔗 niemanlab.org
    OpenAI's ChatGPT has been generating New Yorker-style cartoons signed with the real pen names of more than 15 of the magazine's cartoonists, including Emily Flake and Jason Adam Katzenstein, without permission. The signatures, which cartoonists call certificates of authenticity, are being reproduced on AI slop. OpenAI says it is addressing the issue, but the signatures persist.
  44. The Philadelphia Inquirer built Scrape, an AI tool to surface hyperlocal news — ▲ 81 · 💬 28 · 🔗 lenfestinstitute.org
    The Philadelphia Inquirer needed a way to find newsworthy stories from fragmented local sources like municipal meetings and Facebook pages. One editor was spending 12 hours a week just gathering leads. They built Scrape, an AI tool trained on the editor's manual tip sheets, with daily feedback loops. After months of refinement, Scrape became critical infrastructure for six newsletters, used by nearly 20 journalists. The case study shares lessons on grounding AI in real workflows and encoding editorial judgment.
  45. AI Can Solve Math Problems, But It Can't Think for Us — ▲ 81 · 💬 39 · 🔗 terrytao.wordpress.com
    Jeremy Avigad argues that while AI can now generate publishable mathematical results, the real challenge is preserving mathematical understanding. He offers three responses: solve harder problems that AI can't cobble together, think bigger thoughts by choosing our own questions, and try new things by embracing AI as a tool. He also addresses early-career researchers, urging the community to stand with them and keep mathematics strong.
  46. New AI Training Method Matches Backpropagation Without Backprop — ▲ 76 · 💬 7 · 🔗 qlabs.sh
    Dust, a zeroth-order method, perturbs activations independently at every token, turning each token into a virtual population member. This lets one forward pass evaluate thousands of candidates in parallel, making it up to 10,000 times more efficient than weight-space evolution strategies like EGGROLL. Surprisingly, larger models are more population-efficient, and at scale Dust can exceed backpropagation, hinting that brute-force search may rival gradient-based learning in compute-rich regimes.
  47. Tufte's Data-Ink Ratio: Why Chasing 100% Is a Mistake — ▲ 73 · 💬 36 · 🔗 tuftesrazor.scienceux.org
    Edward Tufte's data-ink ratio measures how much of a chart's ink actually shows data. This interactive guide takes apart a cluttered bar chart step by step, showing how the ratio rises from 3.4% to 9.0% as you erase non-data ink. But pushing to 100% strips away titles and labels, losing information. The lesson: keep ink that helps readers, cut the rest.
  48. Nightwatch - Mac menu-bar app for telescope imaging conditions — ▲ 70 · 💬 11 · 🔗 github.com
    Nightwatch is a silent macOS menu-bar app that tells you when tonight is clear enough for a long imaging session and what to point at.

With a customizable go rule, it recommends the best targets for your telescope and clear window. It also shows the week ahead, dark sites, your horizon, and celestial events. Free and open source under MIT.
  49. GNOME Security Lead: AI Vulnerability Scanning Is Now Non-Negotiable — ▲ 66 · 💬 1 · 🔗 blogs.gnome.org
    Humans are bad at writing secure code, and GNOME developers are no exception. But AI has changed the game: language models can now find vulnerabilities in software with impressive accuracy. In 2026, skipping AI vulnerability scanning is delusional and unfair to users. The flood of AI-generated bug reports has overwhelmed volunteer maintainers, yet banning them is like banning all vulnerability reports. GNOME's CVE count has skyrocketed, and the bug bounty program closed due to the deluge. We must adapt, not stick our heads in the sand.
  50. Babylonian schools taught gods, not scripture — ▲ 63 · 💬 41 · 🔗 cambridge.org
    In first-millennium BCE Babylonia, religious education was not a separate subject but woven into the scribal curriculum. Students learned about gods, temples, and rituals through excerpts of myths, hymns, and prayers, with no holy scripture or secular-religious divide. The curriculum varied by region: northern schools emphasized Babylon and Marduk, while Nippur focused on local deities. This study shows how education transmitted religious knowledge and imperial ideology to future elites.
  51. Med-El Launches World's First Fully Implanted Cochlear Implant — ▲ 61 · 💬 54 · 🔗 spectrum.ieee.org
    Med-El's TICI Unico hides its microphone, sound processor, and rechargeable battery entirely beneath the scalp, ending the external hardware that has long limited daily life for cochlear implant users. The 20-gram device won European approval, and the first four commercial implantations were performed the morning of the announcement. A 30-patient trial found hearing performance comparable to conventional implants, while letting users hear while asleep, swimming, or recharging.
  52. OpenAI's text watermarking is easy to erase: swapping 25% of words drops detection to 17% — ▲ 61 · 💬 49 · 🔗 openai.com
    OpenAI is rolling out textGrain, an invisible watermark for ChatGPT and Codex text in the EU, and opening detector access to approved researchers. The technology performs well on long passages but struggles with short, constrained text like math, and editing can weaken the signal dramatically. OpenAI says watermarking doesn't measure human contribution, establish ownership, or verify accuracy, and it won't be a global default at launch.
  53. Greenvolt starts building a 2.4 GWh battery in Poland — ▲ 60 · 💬 39 · 🔗 ess-news.com
    Greenvolt Power has broken ground on a 600 MW/2.4 GWh battery energy storage system in Siedlce, Poland, with BYD Energy Storage supplying the batteries and commercial operation targeted for the end of 2027.

Together with its Turośń Kościelna and Ełk projects, Greenvolt will reach 1 GW and 4 GWh of storage capacity in Poland.
  54. AI companies are parasites — ▲ 59 · 💬 35 · 🔗 coryd.dev
    Cory Dransfeldt argues that AI companies operate as parasites on society: they scrape the internet without compensation, train models on stolen data, sell metered access, and repeat until the host is killed. The old bargain of traffic for indexing is gone, replaced by scrapers that overload infrastructure, collapse clickthroughs, and destroy communities. Licensing deals like Reddit's still depend on human-generated data from flagging communities. Data centers bring pollution, higher utility rates, and few lasting jobs. The result: stilted prose, derivative images, and incomprehensible code.
  55. After Bankruptcy, He Self-Excluded from Sportsbooks. Then Kalshi Reeled Him Back In. — ▲ 58 · 💬 56 · 🔗 npr.org
    Thomas, 35, filed for bankruptcy after racking up $75,000 in gambling debt, then self-excluded from DraftKings and FanDuel. Two years later, a Kalshi ad on Instagram offering a $20 bonus for $10 spent pulled him into prediction markets, where he lost over $25,000. Kalshi calls him a 'cherry-picked case,' but counselors say his story is increasingly common as prediction markets aggressively advertise without state-mandated self-exclusion protections.
  56. Beating the Compiler: Writing an Interpreter in Assembly — ▲ 57 · 💬 41 · 🔗 mattkeeter.com
    Matt Keeter wrote a fast interpreter for the Uxn CPU in Rust, but profiling revealed that the dispatch loop consumed over a third of runtime. Inspired by LuaJIT, he rewrote the interpreter in hand-written AArch64 assembly, using indirect threading and keeping all state in registers. The result is a 2400-line assembly implementation that outperforms the compiler-generated code.
  57. Young men's mental health is in freefall, and experts warn it could get worse — ▲ 57 · 💬 82 · 🔗 cbc.ca
    Depression, anxiety, and addiction are rising sharply among young men in Canada. Federal data show mood disorders among men aged 15–24 jumped from 11% to 16% between 2012 and 2022, while those rating their mental health as very good or excellent fell from 70% to 52%. Social media, online gambling, and the manosphere are blamed. A new federal strategy is promised by early 2027.
  58. Gitframes renders video directly on WebGPU, skipping the headless browser entirely — ▲ 56 · 💬 37 · 🔗 github.com
    Gitframes is an npm package that turns video composition into pure software engineering: your coding agent writes a TypeScript scene, checks frames, and renders an MP4 straight to the GPU via Dawn, WebGPU, Metal, or Vulkan. It folds Photoshop-grade VFX, After Effects-style motion, and Blender-style 3D into one lightweight library, using roughly 200–400 MB of RAM per render instead of Chromium's 1.5–4 GB.
  59. Lift Their Legs: The CPR-Free Move That Can Save a Life — ▲ 56 · 💬 47 · 🔗 bookofjoe2.blogspot.com
    Most people freeze when someone collapses, and few know proper CPR. A physician's trick requires no training: raise the victim's legs to waist height. This shifts blood from the periphery back to the heart and lungs, where it's needed to restart a heartbeat. It's equivalent to transfusing two units of blood — 40% of an adult's circulating volume — and makes CPR far more effective. Best of all, it can't cause harm.

  61. Optimistic Lock Coupling Scales Read-Heavy Trees Without the Usual Race Conditions — ▲ 50 · 💬 9 · 🔗 databasearchitects.blogspot.com
    A binary tree with lock coupling suffers physical contention on the root lock, limiting scalability on many-core CPUs. Optimistic Lock Coupling lets readers avoid writes, but risks races if validation is forgotten. The author shows how to encode validation in the type system using unvalidated values and optimistic views, so the compiler enforces correctness. The result is near-lock-free read scalability with safe concurrent writes.

    A 30-year-old Florida woman was arrested after Anthropic's Claude AI flagged her chat for violent threats against the Lee County Sheriff's Office. Human reviewers then reported the messages to police. The case highlights how AI systems can trigger real-world law enforcement action.
  63. Voters Are Asking ChatGPT How to Vote in the Midterms — ▲ 47 · 💬 77 · 🔗 npr.org
    With the midterms underway, some voters are turning to AI chatbots like ChatGPT, Gemini, and Claude to research their ballots and even decide who to vote for. NPR spoke with voters using these tools for down-ballot races, while experts warn that chatbots' eagerness to please can subtly reinforce existing preferences without deepening understanding.
  64. This Hacker Made a Blu-ray Backup That Only Survives a Fire If You Give It to a Friend — ▲ 46 · 💬 44 · 🔗 smyck.net
    After burning M-Disc Blu-rays, the author built 'Holocron': a sealed, foam-padded B&W outdoor case holding 3-4 discs of essential data—documents, music, photos, and reboot essentials. The case is given to trusted friends as a decentralized last-resort backup, refreshed every 1-3 years with a handover ceremony to check the tamper-evident seal. The post details the case, foam, custom label, serialized seal, and even a silica gel bag.
  65. Texas city demands $2.3M for records on Flock surveillance — ▲ 44 · 💬 6 · 🔗 arstechnica.com
    As bipartisan backlash against Flock grows, North Richland Hills officials told the Texas Privacy Coalition that searching a terabyte of communications about errors, misuse, and effectiveness would take 14 years of labor at $15 an hour. Other agencies have quoted up to $121,000, while some hand over hundreds of thousands of pages for free. The fees may be hiding data that has triggered audits, arrests, and camera removals.
  66. Philosopher Challenges AI Consciousness Believers with Six Questions — ▲ 40 · 💬 187 · 🔗 endsdontjustifythemeans.com
    A philosopher offers six questions to clarify debates about AI consciousness, arguing that many disagreements stem from conflating 'conscious' with having an internal world. The piece, written as a choose-your-own-adventure, urges specificity about what 'AI' refers to—models, conversations, companies, or something else—and criticizes philosophers for failing to share basic distinctions with the public.
  67. Example.com's Biggest Redesign in Decades Adds JavaScript That Cycles Through Six Languages — ▲ 37 · 💬 22 · 🔗 debugbear.com
    IANA has given example.com its biggest visual overhaul in over 20 years. The reserved domain now uses JavaScript to cycle its documentation message through English, Arabic, Chinese, French, Russian, and Spanish every five seconds, with a character-by-character opacity animation. The JavaScript also inserts an SVG book icon. IANA says the change reduces bandwidth for automated traffic, which rarely fetches the script. The redesign follows a Cloudflare migration and years of sporadic tweaks.
  68. Minigraf - Embedded bi-temporal graph database in Rust — ▲ 31 · 💬 29 · 🔗 github.com
    Minigraf is a tiny, single-file embedded graph database written in Rust that brings Datalog queries and bi-temporal time travel to AI agents, mobile apps, and the browser. Think SQLite for connected data with full history: query relationships recursively, travel through transaction and valid time, and embed anywhere from native to WASM. Zero configuration—just open a .graph file. It's ideal for AI agent memory, offline-first mobile storage, and GraphRAG patterns. Try the browser playground or visualizer to scrub through history and see the graph change.
  69. Microsoft brings Linux containers natively to Windows with WSL containers — ▲ 29 · 💬 8 · 🔗 blogs.windows.com
    WSL containers are now generally available, letting developers build and run Linux containers directly on Windows via the wslc.exe CLI or API. The release adds lifecycle and networking commands, health checks, and enterprise controls through Intune and Defender for Endpoint.

  70. GNOME developer: AI vulnerability scanning is now mandatory for secure software — ▲ 29 · 💬 65 · 🔗 blogs.gnome.org
    Humans are bad at writing secure code, and GNOME developers are no exception. AI has improved considerably, and offers a magic fairy wand solution: we can now simply ask a language model to look for vulnerabilities in our software. There is zero hope of maintaining quality software in 2026 without AI vulnerability scanning. Any claims to the contrary are unserious and delusional.
  71. The Third Way of Using Linux: Why the Text User Interface Deserves a Comeback — ▲ 26 · 💬 40 · 🔗 hisvirusness.com
    Linux users typically choose between the command line and graphical interfaces, but a third option—the text user interface (TUI)—offers a middle ground. TUIs are text-only yet more approachable than raw commands, and they avoid the heavy dependencies of X11 or Wayland, saving RAM. The author argues that in 2026, with RAM prices high and a shift away from bloated frameworks, it's time to make the TUI a first-class user experience on Unix-like systems. Though limited for graphics and gaming, TUIs could form a cohesive environment that inspires more TUI-native development.

  73. A JavaScript Port of River Raid, Rebuilt from the Atari 2600 ROM One Instruction at a Time — ▲ 20 · 💬 11 · 🔗 plicerin.github.io
    Carol Shaw's River Raid has been recreated in JavaScript by rewriting every 6502 instruction from the original 4,096-byte cartridge. The port runs the real ROM alongside a 6502 core and compares every frame, finding zero differences across 45,000 frames. The river is never stored; it's generated on the fly from a 16-bit random number generator seeded at $A814, making it endless yet identical every play. The port also preserves obscure quirks, like collisions at the top of a newly scrolled block being misattributed to a nonexistent seventh block.
  74. DEDA: The Toolkit That Exposes and Erases Your Printer's Secret Tracking Dots — ▲ 20 · 💬 1 · 🔗 github.com
    DEDA is an open-source toolkit for extracting, decoding, and anonymising the yellow tracking dots that most commercial colour laser printers secretly embed in every printout. It offers a GUI and CLI tools to read tracking data from scans, compare documents to identify a specific printer, extract unknown dot patterns, create custom tracking dots, and remove tracking data from both scanned images and PDFs before printing. The project is based on a 2018 ACM IH&MMSec paper.
  75. LLMs make building a tool for yourself worth it — ▲ 20 · 💬 6 · 🔗 armstr.ng
    A personal essay on how LLMs changed the economics of building small tools. The author spent an hour and three prompts to create heade.rs, a domain lookup tool that avoids the ad-filled, upsell-heavy free tools. It costs less than a cup of coffee per month and doesn't need to sell anything. The piece argues that cheaper software lets more people build for an audience of one, though discoverability remains a challenge.
  76. Why Your Algorithm Settles for the Wrong Answer — ▲ 17 · 💬 1 · 🔗 pvk.ca
    In program analysis, fixed-point computations often converge to the least or greatest fixed point depending on initial assumptions. The author notes that humans consistently develop algorithms that converge to one extreme, as if we have a common blind spot. For example, dead value elimination typically starts with all values live and prunes, yielding the greatest fixed point, but we actually want the least. The same pattern appears in student union strike mandates in Québec: starting with unions already on strike leads to deadlock, while starting with all mandated unions and removing those not meeting conditions finds the greatest fixed point. The author argues that choosing the right initial value is crucial, and that settling for suboptimal solutions should be a deliberate choice, not an oversight.
  77. 12 Zigbee Temperature Sensors Tested: One Costs $4.60, Another $19.99 — ▲ 15 · 💬 1 · 🔗 smarthomescene.com
    I bought 12 best-selling Zigbee temperature and humidity sensors from AliExpress, covering Aqara, Sonoff, Tuya, Thirdreality, Zemismart, and Moes. I calibrated a Xiaomi Miaomiaoce MHO-C401 against a state-certified butcher's thermometer and tested all sensors under identical conditions with Zigbee2MQTT. The results reveal big differences in accuracy, reporting intervals, and build quality—even among sensors with identical specs on paper.
  78. Hot Flashing Guide Rev. 2.0: How to Revive a Dead BIOS by Swapping Chips While the PC Runs — ▲ 13 · 💬 2 · 🔗 archive.techarp.com
    Dr. Adrian Wong's 2004 guide explains hot flashing: replacing a corrupted BIOS chip with a good one while the system is powered on. This risky procedure can revive an otherwise dead motherboard, saving the cost and hassle of a replacement. The guide details the method, requirements, and precautions.
  79. ProPublica Reporters Became Private School Owners in 24 Hours — ▲ 12 · 💬 0 · 🔗 propublica.org
    ProPublica reporters tested how easily private schools can be opened in Arkansas, West Virginia, and North Carolina. In Arkansas, they formed a school with a $45 form and an American flag; in West Virginia, a handwritten application on notebook paper sufficed. Both states approved microschools without background checks or curriculum review. North Carolina required school-specific inspections, so they stopped. The experiment shows how little oversight some states provide for schools that can receive public funds.
  80. Ephemeral Testing: A New Way to Validate Software with AI — ▲ 12 · 💬 0 · 🔗 lemire.me
    Daniel Lemire proposes ephemeral testing: instead of directly testing a core library, you have an AI agent build a throwaway application on top of it and test that. A clean API and stable invariants let the agent succeed quickly; hidden state or poor docs produce failures. Those failures reveal the quality of your foundation, not the agent. Lemire has used this trick on his own projects.
  81. AI Is About to Graduate Mathematics from Heroic Exploration to Industrial Mapping — ▲ 11 · 💬 7 · 🔗 docs.google.com
    Christian Szegedy compares pure mathematics to exploring a perilous jungle, where explorers climb rocks to hone tools. AI is like the first airplane: primitive but improving fast. It has already solved conjectures, upsetting explorers who fear flag-planting ruins their sport. Szegedy argues this is a static-thinking fallacy. Soon, cheap AI will map the entire mathematical terrain, shifting rewards from heroic climbing to steering fleets and explaining findings. Mathematics will graduate into the infrastructure of science, and he can't wait to see it from his supersonic airplane.
  82. Jack Smith's FBI Tracked Susie Wiles' Calls to Journalists and Lawyers — ▲ 10 · 💬 0 · 🔗 dailysignal.com
    Newly released documents show former special counsel Jack Smith's team used a pen register to monitor the phone communications of Susie Wiles, then Trump's campaign chief, including contacts with at least five journalists, 21 defense attorneys, and political advisers. The FBI also asked Google, Microsoft, MSN, and Yahoo to preserve her email data, and tracked social media posts of Trump allies like Robert O'Brien.

  84. Dostoevsky slashes LSM-tree merge overhead by merging only the largest level — ▲ 7 · 💬 0 · 🔗 nivdayan.github.io
    Dostoevsky introduces Lazy Leveling, a design that eliminates merge operations from all but the largest level of an LSM-tree, improving update cost without degrading point lookups, long range lookups, or space amplification. The Fluid LSM-tree generalizes the design space, and Dostoevsky adaptively navigates it based on workload and hardware. Implemented on RocksDB, it strictly dominates state-of-the-art key-value stores in performance and storage space.
