StarScope Global provides free, mobile-first citizen astronomy across both hemispheres, with hemisphere-aware real-time sky feeds, tonight's sky panels, and tailored recommendations. Real-time alerts from NASA GCN transients, NOAA space weather, near-Earth objects, and MPC circulars; auto-updating Arxiv preprints with keyword filtering; and a global moderated community with equipment guides. It champions true hemisphere parity, giving Southern observers first-class tools rather than a Northern-centric, membership-based experience.

Krugman argues Musk's wealth rests on investor faith, a 'human Ponzi scheme' powered by Wall Street and politics rather than profits. He notes real successes (Tesla, Starlink) but many promises (Hyperloop, Boring tunnels, Neuralink, Mars) have not materialized. SpaceX IPO valued at ~$1.77T despite $18.7B revenue and losses, funded by belief in Musk's genius. Banks offset losses; index providers added SpaceX to major indices, driving demand from index funds. Ordinary Americans with mutual funds are effectively financing this by belief.

Explains how the Capitoline Wolf weaves Siena and Rome's foundation myths. Siena’s legend says Senius and Aschius founded the city and adopted Romulus and Remus’s wolf; Rome’s tale centers on Romulus and Remus nursed by a wolf. In Siena, the wolf appears in Piazza Tolomei, Torre del Mangia gargoyles, Palazzo Pubblico, and the Fonte Gaia fountain; in Rome, the Capitoline Wolf stands on Capitoline Hill. The emblem links the two cities’ origins and endurance, shaping Siena’s identity and its art and monuments.

James Propp presents six puzzles that look different but share a single trick: add a temporary extra object to make the solution work, then discard it (the “camel trick”). Puzzle 1: borrow a camel to total 18 and split as 1/2, 1/3, 1/9 to give 17. Puzzle 2: add four blue coconuts; smallest original N = 3121. Puzzle 3: connect two trees with one edge to form a tree (E=V−1), then remove it to get 8 edges. Puzzle 4: with a known good coin, two weighings suffice. Puzzle 5: expected cards to first jack = 10.6. Puzzle 6: grand swap returns the deck to order after N+1 steps. Endnotes discuss the trick’s broader use.

Greptile's TREX embeds code execution into AI code review, moving beyond static diffs by running code in disposable sandboxes per PR and capturing multi-modal artifacts (screenshots, logs, traces, scripts, video) to show exactly what happened and why. TREX agents are orchestrated inside the main Greptile reviewer, sharing context, with per-issue subagents handling setup and execution. They use a model-agnostic evaluation harness to compare providers and measure recall/precision, prioritizing accuracy over speed. The goal is a reproducible, evidence-backed validation suite that surfaces runtime bugs and validates changes end-to-end.

Cloud browsers were made 3x cheaper and faster by running each browser in its own tiny VM on regular EC2 via Firecracker, managed by a real-time control plane (autoscaling without unikernels). Key gains: resume-from-snapshot memory with 2MB pages and custom userfaultfd handling reduced startup from 9.8s to 3.1s; CPU pinning and real-time vCPU priorities improved scalability; headless, patched Chromium plus broad fingerprinting boosted stealth to ~81% (and 84.8% on Halluminate). End-to-end latency: p50 825ms, p99 1.35s for 10k sessions; next step is snapshotting after Chromium to skip startup.

Pew Research finds only 16% of Americans expect AI to positively impact society over the next 20 years; about 40% expect negatives. Sixty-seven percent doubt the US government will meaningfully regulate AI, and 59% mistrust companies to develop it safely; under-30s are most negative (14% positive). Yet AI use is rising: ~25% use chatbots daily; 44% use OpenAI’s ChatGPT, with Gemini 24%, Copilot 17%, Meta AI 14% following. Men are more active users; women more skeptical. Roughly 60% read AI-generated summaries; about half don’t use AI daily, especially older adults.

deconvolution is a Rust image deconvolution/restoration library. It offers known-PSF restoration, blind deconvolution workflows, PSF/OTF conversion, preprocessing, simulation fixtures, and ndarray APIs. It includes a wide range of PSF methods (inverse, Wiener, Richardson-Lucy, regularized variants, Krylov, etc.), blind methods (blind RL, maximum likelihood, parametric PSF estimation), and supports PSF/OTF types (Kernel2D/3D, etc.). Preprocessing tools (edge taper, apodization, NSR estimation), deterministic simulation of blur/noise, and 2D/3D workloads. Optional features: rayon (default) and f16 support. Compatible with common DynamicImage variants; MIT license.

Argues that meaningful problem solving often emerges from casual dialogue rather than solitary thinking. Speaking imposes structure; listening provides real-time feedback that reveals hidden assumptions. Theories by Mercier–Sperber, Vygotsky, and Clark–Chalmers frame reasoning as social and extended into the environment; relationships become cognitive infrastructure—the “dialogue dividend” built through many conversations. Remote work and AI diminish informal exchange, risking erosion of trust and understanding. To harvest the dividend, protect unscheduled time, invite opposing views, and prompt AI to reason from alternatives rather than parroting first answers.

Polypore is a modular, agent-centric desktop IDE designed for agentic coding. Built with Tauri, React, Dockview, and Monaco, it treats every surface as a sandboxed panel behind a shared contract, with extensible plugins and an agent-driven MCP server. It offers eight built-in panels (Claude CLI, Codex CLI, preview, editor, diff, terminal, memory/knowledge base, and formation/skills) and 22+ agent tools via the MCP sidecar, plus secret handling via OS keyring where plaintext is never exposed. Includes Polyflow commands and full architecture details; prerequisites are Node 20+, Rust; MIT license. Latest release: v0.1.0 (2026-06-17).

Forum posts discuss the Volkswagen app's compatibility on GrapheneOS and other non-standard Android builds. Users warn that modern cars’ modems collect telemetry and can be remotely controlled; linking a phone may widen data exfiltration. Several users report mixed success: disabling/enabling Google Play Services, reinstalling via Play Store, or updating GrapheneOS can temporarily restore access, but issues persist or return. Volkswagen official reply states the app is only supported on iOS and Android devices with supported OS versions; custom ROMs/special configurations are not supported, with limited help due to reliance on security components and certified Android standards.

US Defense officials say generative AI is speeding congressionally mandated reporting. GenAI.mil can draft reports that once took 200 staff-hours in about five hours, per CTO Emil Michael. Access expanded across all six services, and by June 2026 roughly 1.5 million DoD personnel were using AI tools (up from 80,000 in December 2025). The DoD faces hundreds to over 1,400 required reports and seeks a $1.5 trillion 2027 budget. DoD has signed deals with eight frontier AI firms—SpaceX, OpenAI, Google, Nvidia, Reflection AI, Microsoft, AWS, Oracle—for classified use; Anthropic is excluded. Critics warn of AI errors and accountability gaps.
