Georeactor Blog summarizes Lianda: A Chinese University in War and Revolution (John Israel, 1998), via Yang Xiao’s 2018 trek retracing the Changsha–Kunming march. It portrays Lianda as a wartime merger that fused cultures and nurtured scholars, including Yang Chen‑Ning and Tsung‑Dao Lee; surveys campus life, politics, and curricula under invasion and civil war, and notes mid‑century shifts toward Maoism. The piece links Lianda to Shanghai’s cosmopolitan legacy and ends with Israel’s later research and life.

An interactive tool that charts Hacker News trends over ~18 years using live date-histograms (45M posts) powered by Upstash Redis Search. Users overlay terms, filter by term/author, and select ranges to see the underlying stories and comments. It includes many side-by-side comparisons (OpenAI vs Anthropic; Docker vs Kubernetes; TensorFlow vs PyTorch vs JAX) across AI, languages, tooling, cloud, security, and more, with code available on GitHub.

secs-man is a Rust command-line tool for securely backing up, restoring, and verifying secrets using age encryption and coreutils, aiming for vendor-lock-in-free, long-term accessibility. It supports local and remote secrets, creates timestamped encrypted snapshots, and uses a .secrets-manifest to list items with optional owner and mode. Exports encrypt with a passphrase and include sha256 integrity checks; imports decrypt with the same passphrase. Designed to be reproducible with standard tools so data remains accessible even if secs-man disappears. Install via nix, cargo; remote ops via secs-man-ssh; manual recovery described.

Krugman contends today’s hostility to AI isn’t mere skepticism but a multifaceted backlash. People fear AI because firms marketed doomsday scenarios for profit, then faced backlash when those claims proved unreliable. AI is being foisted on workers and consumers via market pressure and platform changes (e.g., search), eroding personal choice. Visible datacenter footprints—from energy use to pollution—fuel local opposition. Trust in tech firms has collapsed since 2015–2022, and AI crystallizes the public perception of a wealth- and power-concentrating oligarchy. The backlash shapes politics, with money influencing but often failing to sway AI policy.

Marc Seitz (oss/acc) accuses Nico Laqua and UseCorgi of copying Papermark’s open-source and enterprise-licensed code for a data room, alleging copyright and license infringement and demanding immediate takedown. He calls it fraud and says it harms YC community credibility. CCs Garry Tan, Snowmaker, and Y Combinator; the post has wide engagement on X.

Apple hikes prices across Mac, iPad, and more amid surging component costs, especially memory for AI servers. New starting prices include MacBook Neo $699; 13" MacBook Air $1,299; 15" MacBook Air $1,499; M5 MacBook Pro $1,999; M5 Pro $2,499; M5 Max $4,099; iMac $1,499; Mac Studio up to $5,299; iPad line up to $1,499; iPad mini $599; Apple TV 4K $199; HomePod $349; HomePod mini $129; Vision Pro $3,699. iPhone and Apple Watch prices unchanged. Apple says the increases are unavoidable after severe cost pressures and that it had shielded customers until now.

Karl Tryggvason outlines building In the Long Run, an app that plots runners’ progress with points of interest (POIs) along global routes. He created a GeoNames–based pipeline, filtered to parks, historic sites, etc., trimmed to ~725k POIs, then matched them to routes using bounding boxes and a 50 km distance rule. An LLM (Anthropic Haiku) rated POIs with Wikipedia/Wikidata signals, but hallucinations and grounding issues led to relying on Wikipedia summaries instead. The piece discusses English-bias, per-route tuning, and evaluating “taste” without ground truth. V1 shipped; try it at InTheLongRun.app.

Democracies and authoritarian regimes compete in mass surveillance, undermining human rights and privacy. The piece surveys US capabilities (Section 702, PRISM, Upstream, XKeyscore), UK Tempora, and the Fourteen Eyes, noting broad data sharing and data brokers. It argues mass surveillance persists post-Snowden, with encryption evolving but governments expanding tactics. It contrasts EU attempts to curb surveillance (GDPR) with moves in France, Hungary and the UK, and highlights China's total surveillance (Great Firewall, Sharp Eyes, grid system). Mass surveillance risks eroding free societies; privacy protections and VPNs are urged.

LastPass says a breach at its partner Klue exposed limited business contact and CRM data, including customer names, phone numbers, emails, physical addresses, plus support case and sales data. Vault data remained unaffected. LastPass revoked Klue employee access, rotated API tokens, notified law enforcement, and is investigating with Klue and Salesforce. Because Klue connects to Salesforce and Gong, customers should beware of phishing using exposed data. The attackers' IPs and sender domains were shared for detection. This follows prior LastPass breaches (2015, 2022).

Benchmark results depend on test setup. The post shows that small changes to ClickBench—keeping engines alive between queries, increasing hot iterations, or using Parquet vs native storage—can reorder leaders. In Parquet tests, DuckDB and Polars lead when run fresh, but persisting processes benefits DuckDB and shifts the ranking. In native storage tests, QuestDB leads while CrateDB can fail some queries. With longer JVM warmups and a kept-alive DuckDB, it overtakes QuestDB. Takeaway: benchmarks are useful but not definitive; compare workloads and use multiple benchmarks for a real picture.

Treat security as a business enabler and product that supports software delivery, not an end in itself. The DevSecOps relationship is a coordination game with information asymmetry and moral hazard, where misaligned goals hurt cooperation. Promote “we-thinking” and joint goals, make group salience explicit, and align rewards for shared outcomes. Use a hybrid of outcome and process accountability, framing goals as complementary rather than conflicting. Encourage cross-functional tools and practices that serve both security and performance, publicly recognize joint success, and avoid punishing individuals for systemic risks.
