Ordinary WiFi can now identify you with near-perfect accuracy

Researchers show that ordinary WiFi routers can identify people by analyzing beamforming feedback information (BFI) sent by WiFi devices. Using unencrypted signals, they created radio-based images of rooms and recognized individuals within seconds. In a 197-participant test, identities were identified with nearly 100% accuracy from multiple viewpoints and regardless of walking style, and even if the observer or the target does not carry a WiFi device. The study flags privacy risks and urges safeguards in the IEEE 802.11bf standard.

Archie G. Norcross' Maine Forest Fire Maps (1918–22)

Archie G. Norcross’ Maine Forest Fire Maps (1918–22) showcase circular panoramic maps centered on Maine fire towers, used to locate smoke plumes and coordinate firefighting. Drawn for the Maine Forestry Department after devastating 1903–08 fires, these maps—accompanied by alidades—helped lookouts scan the landscape. The article ties in Jack Kerouac’s “panoramic” imagery, noting that mid‑century towers were superseded by cameras, satellites, and aircraft, with many lookouts dismantled or closed. The piece features open-licensed Norcross maps from the Maine State Library.

AI Coding Without the Vibes

The piece argues neither to ignore AI nor to cede coding entirely to it. It proposes "craft coding": write code by hand and use AI as a reviewer to check and critique your work. Through a bakers analogy (hand coder, vibe coder, craft coder), it argues science code benefits from craft coding: ensuring correctness, reducing bugs, and preserving learning and skill, while acknowledging that AI can enhance security and efficiency. It cautions against deskilling and polarization, endorsing a center-ground approach with practical practices and ongoing self-checks.

Clamiga: Common Lisp for the Amiga

Clamiga is a lightweight, self-contained Common Lisp implementation targeted at Amiga systems (68020/68k AmigaOS 3, MorphOS PPC), with ports to macOS and Linux. It uses a single-pass S-expression -> bytecode VM, a 32-bit tagged value model, a compact GC, and a m68k JIT for Amiga hardware. It includes CLOS, condition system, and full numeric tower; ASDF and FASL support; Quicklisp compatibility with shims. MorphOS build is native PPC without JIT; m68k build is JIT-enabled. It provides Amiga GUI bindings (Intuition, Graphics, GadTools), FFI, threading, sockets, and an inspector; development via SLY on host. Status: early/stable with roadmap.

The weekend is 100 years old

Celebrating a 100-year-old weekend, the piece traces its rise from Ford’s 1926 five‑day week to a culture of rest that fueled consumer capitalism. It notes earlier experiments (US five days, Boots), and shows how the weekend shifted with minibreaks, sporting rituals, and the split between ‘time owners’ and ‘time slaves’ in a hybrid-work era. With four‑day-week pilots, Friday off-peak trials, and weekend emails, the ritual persists but is increasingly stretched as work seeps into rest.

GPS and the Lost Art of Getting Lost

Shayla Love, citing Katherine Dunn’s Little Blue Dot, argues GPS has reprogrammed how we find our place. Israeli GPS spoofing shows how digital directions can mislead, while studies link heavy GPS use to weaker cognitive mapping and fewer remembered landmarks. We increasingly center the world on a blue dot, risking loss of navigation skills. A personal foray into an orienteering course without GPS reveals the value of map-reading, patience, and attention, even as we retreat from traditional ways of getting lost.

St Lucie Nuclear Reactor Unit 1 manually shutdown, 3 control rods drop into core

St. Lucie Nuclear Plant Unit 1 was manually tripped at 9:47 a.m. ET after three control rods dropped into the core while at 100% power. The NRC classified the event as a non-emergency; post-trip, all systems responded normally and the plant was stabilized in Mode 3 (hot standby). Decay heat is being removed via the main condenser and turbine bypass valves/main feedwater. Unit 2 was not affected, and Unit 1 remains shut down.

Show HN: A public AI whose memory is shared across all users

Wild Static is an artificial experience by Plural Matter Ltd. featuring a single AI with one shared memory that everyone talks to. It never resets; what you say may be seen by others. Start fresh, share your name and message, and return later to see how it has evolved.

The AI Credit Resale Economy

Token brokers buy unused startup credits and resell them, turning token relays into a commercial market. Founders report offers via email for off-market inference; brokers act as proxies routing requests from a pool of keys. Marketplaces like AI Credits and AICreditMart sell credits across major providers with discounts (30–80%); bulk-discount platforms such as CheapCredits, Tokvana, and Neokens tout large savings. Telegram and Reddit show activity; one broker advertised $100k/day in spend. The market likely encompasses tens of millions of credits, with abuse and possible crackdowns ahead.

A True Telnet BBS on a Casio Calculator

EI3LH documents building a true Telnet BBS hosted on a Casio VX-4 calculator. Using the VX-4’s 8 KB RAM (expandable to 64 KB) and a Raspberry Pi Zero W as an RS232 bridge and message vault, they run a BASIC-based BBS that users connect to via telnet (4800 baud, one session, later 9600). The system prompts for amateur radio callsigns, stores messages (60-char limit) and logs, with an Adafruit OLED HAT for status. The Pi archives messages to a text file. The project is open-source on GitHub; more features planned.
