Show HN: Critic – Review code with the agent that wrote it

Patch introduces a leased handoff for coding-agent questions to survive disconnects. Only one connected author device can own a question at a time; if a device goes offline, its claim expires after 45 seconds and the question becomes available again. Questions now queue with their session and wait for the author's coding agent rather than assuming online. A short lease token lets any connected device claim work atomically; original session provides context. Updates include making anchor movement conservative and surfacing the answering device in UI, with a Reconnecting state when leases lapse. Files changed: agentQuestions.ts, project-anchor.ts, agent-question-status.tsx.

International observers to investigate Swedish election fraud

OSSE/ODIHR hade före valet bedömt att Sverige inte behövde internationella valobservatörer, trots högt förtroende för valsystemet. Sverigeinförde efter valet förändringar, bland annat ackreditering av valobservatörer. Efter valet uppmärksammades flera misstänkta valbrott: i Borlänge tre personer misstänks för otillbörligt verkan vid röstning; en pågående förundersökning om misstänkt valbrott; två fall av misstänkt röstköp i Piteå och Luleå. Antalet överklaganden låg nära 10 000. ODIHR säger att sådana händelser vägs in vid framtida bedömningar av behovet av observationer och kan leda till en ny behovsbedömning och delegation.

California is chasing wealth that has feet

California has about $8.14 trillion in land value, a vast, immovable base. A billionaire wealth tax would likely fail as wealth has feet and many billionaires moved residency, shrinking the base; to raise $20B/year, rates would rise toward 1–2%, prompting more flight. By contrast, a 0.25% land value tax would raise the same $20B on a larger, inescapable base and capture windfalls from public investment. Land value taxation avoids relocation, unlike income or wealth taxes. Prop 13 under-values property, weakening the tax base; land value taxation is more stable and fair.

Show HN: Koi.rest – watch some fish and regain your balance

Paul Glushak, a developer with ADHD who is currently unemployed, created koi.rest—a quiet, virtual koi pond on the internet designed for strangers to watch fish together and regain balance. Lacking JavaScript skills, he used AI to build the project and embraced 'good enough' rather than perfect. Visitors can stay as long as they want and choose a timer (10, 15, 30, 60 minutes or custom). He hopes the pond helps others and is seeking job opportunities; contact via koi.rest.

The Board Game of the Alpha Nerds (2014)

Diplomacy, created in 1954, is a negotiation-driven strategy game set in 1914 Europe where seven powers try to control supply centers; moves are simultaneous and betrayal is part of the play. Born in fanzines and play-by-mail, it grew into international tournaments, including World DipCon. David Hill’s DixieCon 2014 report chronicles intense alliances, backstabbing, and emotional tolls, from fan-favorites like Edi Birsan to rivals like Thomas Haver. The game’s core claim is that trust, not luck, decides victory.

Security headers on 4,688 small-business websites: 49.7% met none of 7 criteria

RACKCRUNCH studied 7,040 directory-listed U.S. local-business websites to see which security headers they send and how well they implement them. Among HTTP-200 responses from 4,688 final domains: HSTS 43.8%; strong HSTS 12.3%; X-Content-Type-Options nosniff 39.7%; Referrer-Policy missing 86.6%; CSP enforced 21.2% but only 0.17% pass header-only script-CSP; clickjacking 31.2%; version-token disclosure 20.5%; 49.7% meet none of seven criteria. About 19.9% had no usable HTTPS response. Recommendations: enable HSTS with includeSubDomains, deploy CSP carefully (prefer non-inline scripts, nonce/hash), add X-Frame-Options or frame-ancestors, nosniff, Referrer-Policy, remove version headers, start CSP in report-only and test COOP.

Opus 5.5 is good at explainer videos

LaunchVideo uses a one-click serverless agent on OpenComputer to render promotional videos from a URL or prompt. Each job runs in a fresh Amazon Linux 2023 arm64 microVM (4 vCPU, 8 GB), installs headless Chromium and ffmpeg, and uses three tools: web_fetch (page text, colors, fonts), check_scene (JS errors and visible text), and render_video (1920x1080, 30fps, libx264, crf 18). It queries anthropic/claude-opus-5.5 via the model gateway; roughly 90k input and 15k output tokens per film. Output is a public MP4 blob URL; progress is polled via the API. Deploy from diggerhq/shipvideo with one click.

August 27 TCRF DDoS Attack Postmortem

Xkeeper details a sustained DDoS on tcrf.net from Aug 27–Sept 9, 2026 that targeted network bandwidth rather than CPU, forcing Linode to null-route the site. With main and backup servers down, a temporary status page and then a backup server with a new IP were deployed. Attempts to mitigate included Linode’s router blocks, Cloudflare’s Under Attack mode, and a misadventure with Fastly that burned budget and led to a suspension. The attack finally subsided by Sept 9, and improvements included better caching, IPv6, bot blocking, and a plan to use non-Cloudflare access for logged-in users; sporadic HTTP attacks lingered.

Google’s Project Suncatcher to put ML infrastructure in space

Google's Project Suncatcher aims to run scalable AI compute in space. A prototype satellite tests how Google's TPUs perform under radiation, vibration, and vacuum cooling. Early tests show Trillium TPUs tolerate radiation beyond five years of mission dose; space testing will refine design. Cooling in space requires radiators and heat pipes due to vacuum. Future designs envision satellite clusters linked by high-bandwidth lasers to handle larger AI workloads; a two-satellite test is planned for 2027. The project is documented in a video series about the science and engineering challenges behind the mission, with a SpaceX Transporter-18 launch.

Sourcehut account takeover via build logs (XSS in ansi2html)

A wormable XSS in SourceHut’s ansi2html.py (CVE-2026-92973) allowed attackers to inject content into build logs and exploit admins viewing them to execute payloads, potentially gaining admin rights and deploy keys to take over accounts on builds.sr.ht and related SR.ht instances. The vulnerability stemmed from ANSI-to-HTML conversion enabling dangerous OSC 8 links; mitigations included CSP improvements, output sanitization, and upstream fixes. Patch timeline: builds.sr.ht mitigated on 2026-08-04; upstream ansi2html 1.9.4 released on 2026-09-02.

Using LLMs to trace alchemical knowledge and decode 17th century letters

AI frontier models (GPT-6 Sol, Astra; Opus 5.5) can advance historical research when paired with historians, but require tractable problems, fully digitized data, and verifiable results. Breen cites cases in cryptography, cross-language linking, and information flows—e.g., Newton/Hartlib’s vitriol anagram clues; Darwin references; Hartlib’s archive; and deciphered 16th-century letters. He acknowledges results are still scattershot but promising for collaborative work. Solutions hinge on digitizing manuscripts, giving historians free API access/compute, and funding systematic, cross-library projects; he proposes a public list of solvable historical open problems.

A Million Agents Is a Distributed System Problem

Tony Chang argues a single agent is an intelligence problem, but a million agents is a distributed systems problem. Agents are finite and must rely on durable state that outlives any worker. Google Research and MIT found that more agents help parallelizable tasks (up to +80.9%) but hurt sequential tasks (−39% to −70%), with centralized coordination cutting error amplification (4.4× vs 17.2× for independent agents). The fix is OS-like infrastructure: schedulers, memory, failover, and durable ownership of state—via AIOS or LLM-as-Scheduler—rather than endlessly running agents.

Programming Tutorials Are Dead

Rob Race argues that traditional programming tutorials are dead not in the sense of teaching vanishing, but because static sample apps no longer suffice for real work. AI-powered coding agents shift the learning workflow: experts supply decisions, constraints, and context, while agents apply them in the learner’s actual codebase. Education should add an execution layer, not rely on a single walkthrough. Tutorials are being split into concepts and adaptable, codebase-specific guidance. Beginners still need judgment; experienced developers need context to guide automation.
