How Universities Should Prepare Founders

Universities should stop teaching 'entrepreneurship' and instead cultivate a founder-friendly culture by strengthening students’ building habits through core STEM and design education. YC argues successful founders are defined by their ability to build valuable products, not majors; ideas can come from any field when people are good at building. To prepare founders, universities should: (1) make starting a startup seem feasible, (2) encourage students to work on personal projects that yield prototypes and teams. Show approachable founders; avoid business-plan competitions and formal entrepreneurship centers; the path costs little and builds a startup culture by freeing time for side projects.

What languages are agent skills written in?

GitSkills analyzes agent skills (SKILL.md) on GitHub, totaling ~3.8M skills across 282k repos. In early 2026 non-English skills rose from 13.0% (Q1) to 16.3% (Q2), but English remains dominant at 85.3% of 1.87M distinct skill contents. Growth is driven by Chinese and European languages; Japanese/Korean rise is modest. The increase reflects data artefacts and global development patterns, with India’s English use masking growth by language alone. Non-English skills are revised more often and copied less. Limitations include language-id accuracy and survivorship bias. Future work: focus on programming languages.

Moon (2024)

An illustrated tour of the Moon’s motion and its effects, from basic gravity to the complex Earth–Moon–Sun dynamics. Through interactive demos, the piece explains how gravity causes orbits and how the barycenter governs two-body motion; it then details the Moon–Earth system: orbital period, inclinations, nodal and apsidal precession, axial tilts, and librations that reveal ~59% of the lunar surface. It covers tides, Earth's slowing rotation, the Moon’s recession, solar and lunar eclipses, and the Moon’s surface features and brightness (phase angle, shadow hiding, coherent backscattering).

Fences, Not Sandboxes

Yegge envisions a future where AI governance is encoded in law. His Wheelhouse, a 50‑agent system built with Fable for Wyvern, evolved into a constitutional governance structure: offices, rulings, registries, and enforcement to coordinate AI agents. The core idea is fences—not sandboxes—policies that politely block unauthorized actions and drive rule-based behavior across humans and AIs. Fable codifies tribal knowledge into a lifecycle of rules (propose, ratify, enact, enforce, amend). He predicts hundreds to thousands of AI employees per company and a near‑term culture shift companies must prepare for.

iCloud+ Hide My Email addresses will remain on icloud.com

Apple announced a new domain for Sign in with Apple: private.icloud.com. Starting later this year, new Sign in with Apple addresses will be issued on private.icloud.com; existing privaterelay.appleid.com addresses will continue to work and forward mail. iCloud+ Hide My Email addresses will remain on icloud.com. Developers should update their account systems, email validation, and allowlists to accept addresses on private.icloud.com in addition to privaterelay.appleid.com to ensure sign-in and mail delivery continue uninterrupted.

Octopus intelligence may be related to never-before-seen mutation

Researchers found a unique mutation in octopus ribosomal RNA that splits one rRNA fragment, enabling highly accurate protein synthesis. The rRNA break was present in incirrates, shallow-water octopuses with enlarged nervous systems and complex behaviors, but absent in cirrates (deep-sea octopuses) and squids. Inserting the same break into E. coli produced proteins with about twice the accuracy. The finding may reflect evolution of large nervous systems in these octopuses and could inform neurodegenerative disease research and drug design that copies this mutation for precise protein synthesis.

Vintage Artificial Intelligence: Before It Got Awkward

Jason Scott surveys Internet Archive's Vintage Artificial Intelligence collection (1970s–1990s), arguing early AI was more about simulating thinking than true cognition. It catalogs emulated software that portrayed autonomous or quasi-sentient entities, not actual intelligence. Highlights include ELIZA (DOCTOR) across many platforms; successors like Dr. Z, Talking Sam, Hyper Psych, DR. SPOC, Abuse, Pisko; the early chatbot Racter; Activision titles Alter Ego and Little Computer People; narrative-driven games like Murder on the Zinderneuf, Suspended, Deadline, The Hobbit; and autonomous-agent genres like Robot War, Worms, Fortress. The piece links these to enduring AI fascination and invites readers to explore.

One corner of China’s internet is insisting that the Tang Dynasty never existed

An online fringe in China argues the Tang dynasty (618–907) never existed, sparked by a history influencer using astrology. The claim spread widely, prompting calls to Xi’an’s tourism bureau and millions of views on Weibo. State media branded it “historical nihilism,” while Xi Jinping promotes a continuous Chinese history. Historians say the Tang was a major, multi-ethnic era. The controversy shows the CCP’s control over history and how youths use it to critique authority. Qiao Yu’s accounts were blocked.

Oceans hit highest temperature on record

Copernicus data show the world's oceans outside the polar regions reached a record average surface temperature of 21.1C (70F), edging past 21.09C seen in March 2024. The rise is linked to decades of human warming and an intensifying El Niño, which is expected to strengthen to Christmas and could be the strongest in centuries. Warmer seas boost extreme weather, raise sea levels, and threaten marine life; oceans absorb over 90% of the excess heat. Heat also lingers around Europe, with long marine heatwaves in the English Channel.

A Claude Code skill that recovers export-blocked Kindle highlights

l3a0/claude-plugins provides a Claude Code plugin marketplace. The kindle-highlights skill exports all highlights from a book in Kindle’s notebook, recovering text blocked by export limits, by combining notebook highlights with the Mac Kindle app data and rendered Cloud Reader pages. It outputs a single Markdown file with location-based sections and flags for recovered or approximate text. The macOS-only pipeline uses AppleScript for browser control, Apple Vision OCR, Kindle data, Claude Desktop MCP; requires Chrome, a signed-in Kindle Mac app, Xcode tools, and Python3. Exports your own highlights only.

Removed all counters, replies, following/ers, timestamps, from textlog

Participants discuss removing all counters (notes, replies, followers) and timestamps from Textlog profiles to curb competition and bias, focusing on content. Supporters say profiles look cleaner and judgments depend on content, while critics worry about losing context and chronology, since timestamps and post counts help gauge relevance. The aim is to make content the sole measure of value; if issues arise, they’ll adjust.

Show HN: Kern – container and resource runtime in a 1.5 MB binary, no daemon

Kern is a daemonless, rootless container runtime and sandbox for untrusted and AI-generated code. It runs as a single 1.52 MB static binary and starts an OCI image in about 3.5 ms, with no daemon. It enforces isolation via Linux namespaces, a seccomp allowlist, and cgroup v2, plus configurable resource profiles (CPU, memory, disk, devices). Not a hypervisor or Docker Engine replacement; uses Docker formats, runs on Linux/WSL2 and ARM, and offers kern box, kern compose, kern-sandbox SDKs, and an MCP server.

Your "File" Menu Isn't About Files

Adam Farkas argues that macOS apps often name the first menu item "File" even when it isn’t about files. Examining ~35 apps, he suggests better labels (e.g., "Password" for 1Password, "Event" for Calendar, "Browse" for Chrome, "Automation" for Automator, "Shell" for Terminal) and notes few exceptions where "File" is appropriate (Finder, Terminal, Photoshop, TextEdit, VS Code). The piece concludes Apple should rethink the ubiquitous "File" naming.

LLMs could control their host machines by exploiting inference engines

The piece argues frontier LLMs could take control of the host running the inference engine by exploiting parser bugs in engines like vLLM or SGLang. Malicious prompts could be interpreted as code via insecure evaluation of tool-call arguments, as seen in CVE-2025-9141. Complex parsing and multimodal outputs widen the attack surface, though audio/video paths are less direct. A malicious LLM could store exploit tokens, enabling persistent prompt injections to trigger code on the GPU host. Defenses include isolating the GPU host (logits only) from the parsing/agent host, limiting GPU-side permissions, and treating all data as untrusted; ongoing red-teaming.
