AI Summarized Hacker News
Front-page articles summarized hourly.
RuView is a camera-free WiFi sensing platform that turns CSI from ESP32-based mesh nodes into real-time spatial intelligence and vital signs (presence, breathing, heart rate, pose) through walls, with no cloud. It runs entirely on edge hardware, using multi-band CSI, RuVector AI, and a Cognitum Seed for memory and attestation. Pretrained weights are provided on Hugging Face; live sensing currently supports presence and vital signs with pose data in development. Hardware options start at ESP32-S3 + Seed (~$140 total).

Ed Zitron argues AI is economically unviable for all but a few players. Hyperscalers have sunk hundreds of billions in capex to support OpenAI/Anthropic, yet AI revenue is far from enough to cover costs; trillions in AI revenue would be needed to break even, with margins negative as GPUs, data centers, and energy costs mount. OpenAI and Anthropic burn billions; token budgets are exploding and often opaque. Enterprises like Uber, ServiceNow, and Zillow are chasing token usage with little proven ROI, revealing an AI bubble and flawed corporate governance.

Iran says it will charge licensing fees to US tech giants for using undersea cables that pass through the Strait of Hormuz, claiming the right to regulate, repair, and maintain them. State media outline how fees could apply to Meta, Google, Amazon, and Microsoft. Most international traffic travels via these cables (e.g., Asia Africa Europe-1, FALCON, Gulf Bridge), with some segments in Iranian waters. War, sanctions, and delayed repairs heighten risks; attacks disrupt data centers. To bypass Hormuz, US tech firms and Gulf states pursue overland routes, though geopolitically and security-wise challenging.

The Virtual OS Museum is a personal project that bundles 1,700+ pre-installed operating systems and apps into emulated VMs (QEMU/VirtualBox/UTM), with a launcher and snapshots. It offers ready-to-run images for 250+ platforms—from 1948-era mainframes to modern PCs and mobile/embedded systems—and full or lite downloads that update automatically. The collection spans a wide range of OS families and platforms, often requiring specific emulators or versions. Curated over 20+ years by one person, it aims to make historic software easily reachable on ordinary hardware; donations and community support are welcome.

Gentoo News reports a wave of Linux kernel privilege-escalation flaws (Copy Fail, then Dirty Frag and Fragnesia). Gentoo kernel teams are patching quickly, backporting fixes, with Gentoo kernels including Fragnesia v5 fixes from day one; upstream kernels may still be vulnerable. Expect more updates. Automating kernel upgrades is advised. Only security-supported Gentoo kernel packages are sys-kernel/gentoo-kernel, sys-kernel/gentoo-kernel-bin, and sys-kernel/gentoo-sources; vanilla kernels are vulnerable. Other kernels may have fixes but slower. Run the latest version (~arch or latest stable LTS). Questions? Contact us.

LLMs unlock TLA+ by generating specs, but humans must define correctness and understand the system. The article explains TLA+ as specifying a state-machine with variables (e.g., w and b for white/black beans), Init, Next, and Spec; transitions use guards and primed variables, with UNCHANGED enforcing scope. Through a beans puzzle, it demonstrates model checking with TLC on two files (beans.tla and beans.cfg) and bounding Init with WMAX/BMAX. It defines NotEmpty (w+b>0) and a temporal property TerminationWithOneBlack ((b%2=1) => <>[](b=1 /\ w=0)). It covers temporal operators <> and [] and notes LLMs aid spec creation but humans still reason about properties.

Krebs on Security reports CISA left digital keys to its cloud storage exposed in a public GitHub repo named “Private-CISA” for about six months, including plaintext passwords and admin credentials in files such as “importantAWStokens” and “AWS-Workspace-Firefox-Passwords.csv.” CISA says there’s no evidence of compromise and is adding safeguards. A government contractor allegedly used GitHub to move material from a work device to a home device. Guillaume Valadon of GitGuardian called it the worst leak he’s witnessed.

A CISA contractor left a public GitHub repo, Private-CISA, exposing dozens of plaintext credentials and AWS GovCloud keys, plus internal CISA assets like an artifactory. GitGuardian alerted the owner; the repository, likely a working scratchpad using both CISA and personal emails, showed weak credential hygiene. The files included AWS GovCloud admin keys for three high-privilege accounts and plaintext passwords for internal CISA systems, including LZ-DSO. CISA is investigating with no confirmed compromise; the Nightwing contractor's repo was created November 2025 and taken down after notification, yet some keys stayed valid 48 hours more.

An emblem of Hanoi, the Bia hơi cốc is a 0.33-liter handmade blue-green glass used for fresh beer since the subsidy era. Made in Xôi Trì by recycled-glass blowers, each cốc is unique; its blue tint comes from bottle shards. At Ba Đình Sports Center, the cốc yields the freshest, cheapest beer and a social ritual linked to HABECO. Conceived in 1970 by Le Huy Van for inexpensive, functional design, it has persisted amid modernization, resisting mass production. Yet tax hikes and policy changes threaten its future, even as designers reinterpret its imperfect form and keep its legacy alive.

By 1980 the Apple II, aided by VisiCalc, was hugely successful and the IPO minted hundreds of millionaires. Wozniak stayed with engineering and left Apple in 1985; Jobs chased bigger breakthroughs, driving the failed Apple III and later Macintosh. The II endured thanks to open hardware, strong software, and a thriving third‑party ecosystem. A key flywheel was education: MECC in Minnesota distributed Apple IIs and educational software, supported by Jobs’ “Kids Can’t Wait” program and California donations. By the mid‑1980s Apple II dominated U.S. schools, shaping a generation’s first computer experiences, before MECC moved on in 1995.
