Shipping a LaTeX compiler behind an edge app shows TeX cannot run in a Cloudflare Worker; instead, a tiny Node service in a container calls Tectonic over HTTP and returns a PDF. Edge handles requests; TeX runs remotely. Key ideas: Tectonic’s on-demand fetch, multi-pass, no intermediates, and shell-escape off. Security: require COMPILE_TOKEN and fail closed if missing. Each job uses its own temp dir; path-traversal is blocked; /tmp is in-memory. Lessons: host choice can wreck schedules; builds fail for IAM, libs, or glibc; bake cache; front-load risk; assert outcomes; keep portability; document decisions. Next: tailor a CV.

Dovepass is a San Francisco research prototype that helps preflight plan and check drones under Part 107. Users select takeoff, destination, and drone specs; it assesses route feasibility, weather, battery, and compliance with FAA airspace, stadiums, parks, and local restrictions, and then provides a clear answer plus printable files for the drone app. It draws from OpenStreetMap, terrain, FAA UAS Facility Map data, weather feeds, and local park data. It does not authorize flights; always verify rules yourself, and treat data as potentially out of date.

Proof of Human identified 99% of automated sessions across five adversaries, outperforming Google reCAPTCHA v3 (69.4%), hCaptcha (44.3%), Cloudflare Turnstile (42.1%), and Cloudflare Bot Management (9.1%). The results varied by adversary: scripted browsers were caught by most systems, while AI agents and stealth browsers often evaded. reCAPTCHA detected many AI-agent sessions but failed on CloakBrowser; hCaptcha challenged Chromium and CloakBrowser; Turnstile failed to detect AI agents; Bot Management remained weak. Conclusion: bot detection is entering a phase where behavior signals become crucial as browser fingerprints are spoofed; future benchmarks should scale traffic and measure false positives.

First demonstration of a non-mechanical 3D printer driven by a silicon-photonics chip that emits visible-light holograms into a resin well to stereolithographically print 3D objects. An on-chip visible-light optical phased array, with a liquid-crystal phase shifter, non-mechanically steers a 637 nm beam into a visible-curable resin, enabling voxel printing and 2D patterning. They printed a voxel about 0.5 mm by 0.125 mm by 60 μm and a MIT logo, with prints forming in seconds at power. This portable, low-cost approach removes bulky optics and mechanics; future work includes focusing optics, higher power, wavelength flexibility, and volumetric printing.

Brad Phillips narrates his decades-long use of benzodiazepines (Klonopin) and his brutal withdrawal, beginning with CAMH taper advice, describing a suite of physical and cognitive horrors—paresthesias, tinnitus, depersonalization, pain, insomnia, and anxiety—that persisted for years. He traces the drug’s history, aggressive marketing, and medical ignorance that often misdiagnosed withdrawal as MS or other conditions. Citing the Ashton Manual and evolving guidelines (ASAM), he argues for slower, better-managed tapering and acknowledges lasting, transformative effects on his life and identity.

US investigators tie ShinyHunters to executives at ransomware-negotiation firms who courted the group; one US executive allegedly helped run shinywire, an extortion site pressuring victims to pay. ShinyHunters has extorted over $70M this year and hacked the FBI’s fbijobs.gov. Dutch hacker Pepijn van der Stap was arrested; his Signal chats linked to US/Canadian negotiators and a suspected murder-for-hire plot. Canadian Edward Dubrovsky was charged for threatening to disclose stolen data and communicated with ShinyHunters, knowing the FBI breach. The piece highlights industry conflicts of interest in ransom negotiations and cites related DOJ prosecutions; it also notes PowerSchool’s 2024 ransom.

Academics have an ethical duty to defend Wikipedia as open knowledge, as generative AI redirects readers and prompts machine-generated outputs without verification. Wikipedia’s volunteer community risks decline without sustained readership and updates. Grounded in the Social Connection Model, academia can address injustices in knowledge processes and bolster Wikipedia with expertise and resources. Ways to help: contribute content and sources, cite Wikipedia, integrate it into scholarship, and teach students to edit via the Wiki Education Foundation (over 152,000 students at 8,000+ institutions, 125 million words since 2010). Institutions should recognise such public service to maintain trust in higher education.

Meta’s Prometheus is a gigawatt-scale AI supercluster in New Albany, aimed at training frontier models with ~1 million GPUs. Phase one is complete, delivering Muse Wonder with high pretraining and RL goodput and ~54k MTBI hours after fixes. It uses two NVL72 platforms—Catalina GB200 and Clemente GB300—each with 72-GPU domains and high memory bandwidth; Vera Rubin NVL72 and San Miguel are planned. The network spans BE, BAG, and building fabrics with DSF/NSF, optimized by PAFT and checkpointing. Dynamo Dimmer manages power; cooling uses AALC/FLC. Hyperion is next.

The post argues that AI writing erodes author identity and precision. Drawing from a bachelor thesis on identifying authors from short texts, it suggests readers rely on patterns, structure, and style—elements AI averages and obscures. AI writing reduces empathy and makes context harder to infer; even with detailed prompts, it often makes assumptions and yields vaguer language. This loss of precision slows readers, increases verbosity, and erodes trust, offsetting any writer time-savings and complicating collaborative work.

Rouler is a Windows split-tunneling tool that lets you assign apps and services to specific network interfaces, enabling concurrent use of multiple VPNs without interference. It works with WireGuard, Tailscale, OpenVPN, Mullvad, etc., and uses its own Rust driver; it doesn't modify the Windows route table. Rules can target apps and destinations (IP/subnet). It shows a live activity view and routes traffic accordingly. Lightweight, fast, and designed to minimize impact. Free beta now; ARM not supported yet; pricing later. Beta for technical testers; install with a key.

RawLink is a fast, encrypted TCP tunnel written in Rust with optional SSH obfuscation. It tunnels traffic from a local SOCKS5 proxy to a remote server using AES-256-GCM and a pre-shared key for authentication. It supports multiple tunnels, automatic reconnects, and a 17-byte header that is XOR-masked for obfuscation. An extra obfuscation layer can mimic SSH traffic or look like random data. Usage: run server and client with a 64-hex PSK and route via SOCKS. Development ongoing with security audits pending; MIT/Apache-2.0 license.

Anthropic shows Claude designed de novo protein minibinders against five scorpion neurotoxins from four species to block their binding to sodium channels. In 64 hours of autonomous work plus four follow-ups, Claude produced 318,484 designs, shortlisted 180, and with 31 more (211 total) sent to labs. 17 designs met binding criteria, each against a single toxin (Cn2, Ts1, AaH I, AaH II, LqhIII). Lab tests (SPR) yielded KD in single-digit nM for Cn2-B1 and Cn2-B2; none achieved multitoxin binding. No neutralization in cells or animals yet. All designs and data are released to accelerate antivenom research.

Jepsen tested Orkes Conductor 5.3.2–5.5.0-rc2 and found: frequent concurrent execution of the same task within a workflow; pre-execution stalls; occasional null IDs and syntax errors; and three serious safety bugs where workflows were abandoned, lost, or completed without any tasks running. Orkes released 5.5.6 with patches addressing all three serious issues and reducing concurrency, plus fixes for two startWorkflow errors; some issues (#3 null IDs, #6 failed connections) remain under investigation. Upgrade to 5.5.6; ensure idempotent tasks and safe storage choices.

Permit Pending is a browser-based city-simulation where you’re the elected mayor. Every block goes through hearings, lawsuits, and elections as you maneuver a seven-seat council to stay in office while building the city you want. A month-by-month case shows conflicts between developers and residents over zoning, parking, and taxes. Start as a hamlet and grow to a metropolis—or inherit problems. It’s a sandbox forever with no campaign or fixed win screen; you play until voters oust you. No account needed; saves stay on your computer. By Peter Cai, 2026.

Sixteen years after the Deepwater Horizon spill, Gulf deep-sea life shows little recovery. A PNAS study finds ≥60% declines in octopus, squid, krill, shrimp, and lanternfish in the spill’s early years, based on acoustic surveys and thousands of nets. The losses are the fastest, most severe in the deep-sea zone from about 600 feet to over two miles deep; while not proving causation, oil pollution is the most parsimonious explanation. Contaminants persist in squid and octopus flesh and in fish eggs, potentially harming reproduction; genetic diversity has declined, risking adaptability.

October 2026 SlopCodeBench update evaluates frontier models on 36 problems with 196 checkpoints; strict pass rates are 12–16% and core passes 66–74%. Astra XHigh leads strict passes (32/196), but gains over others are modest; higher effort costs 2–4x with little reliability in improving strict passes. The report emphasizes code cleanliness, reveals Opus Medium leaves more code and that cleaner code doesn't always yield more strict passes, and notes Part I of a two-part series.
