Skillscript is a small declarative language for authoring agent workflows, with a runtime, compiler, and CLI. It treats agents as code written in a safe, sandboxed grammar and emphasizes declarative skills (DAGs of typed dispatches) that call swappable connectors—tools, models, and data stores—rather than arbitrary code. Skills come in three shapes (Headless, Augmenting, Template) and can be static or dynamic. Local models are treated as delegation targets; composition lets skills invoke other skills. Security is baked in via allowlists, signed approvals, and connector contracts. It runs over an MCP server with Skillfile CLI for authoring and deployment. MIT.

Climate change helped drive Polynesian eastward expansion after a 1,700-year pause. A severe drought in the southwest tropical Pacific 850–1200 CE coincided with rising island populations, prompting exploration. Between 900–1100 AD, voyagers on large double-hulled canoes reached Hawai'i, Aotearoa, and Rapa Nui, and possibly linked to the Americas via sweet potatoes. The drought was linked to shifts in the South Pacific Convergence Zone and long-term climate patterns, influencing rainfall and resources. The findings connect environmental stress, tech, and social factors to the famed Pacific expansion, as echoed in Moana.

mcp-spec-check is a TypeScript/JavaScript tool that performs black-box probes of MCP endpoints to evaluate readiness for the 2026-07-28 MCP stateless-core migration. It checks three required aspects—discover (replace initialize handshake), routing-headers, and session-independence—and returns a verdict (YES/NO/UNKNOWN) plus a letter grade. The project scanned 7,850 public MCP servers (as of 2026-07-12); 4,356 reachable; only 1 passed all checks; 90.8% not ready yet. It provides usage (npx mcp-spec-check <url>), supports JSON, verbose, timeout, and auth headers; MIT licensed; zero-runtime dependencies. It emphasizes read-only probes and reproducible results.

Two-man Naughty Dog in 1994 pivoted from Way of the Warrior to a 3D platformer for PlayStation. Gavin and Rubin evaluated 3D-capable rivals (3DO, Saturn, 32X) and, drawn to Sony, signed a developer agreement and spent about $35,000 on a dev kit. They aimed to transplant top-selling 2D platforming into 3D, tackling the 'Sonic’s Ass' problem by starting characters facing the screen, including 2D levels, and adding run-into-the-screen boulder segments. With Dave Baggett and Mark Cerny, they began shaping what would become Crash Bandicoot.

New analysis of 41.3 million English-language papers (1980–2025) across six natural sciences finds AI boosts individual productivity and citations—papers by AI users are three times more numerous, nearly five times as cited, and researchers reach leadership roles sooner. But AI-heavy work occupies a smaller intellectual footprint, clusters around popular, data-rich problems, and shows weaker networks of follow-on engagement, risking a more homogeneous science. The authors warn incentives to publish and automate are driving focus on tractable problems. They call for integrating AI across workflows and reshaping rewards to encourage broader, bolder questions.

Blog post detailing unauthenticated remote code execution in Motorola MR2600 router. Attacker uploads a malicious firmware via POST /WEBCGI1/prog.fcgi?method=/cgi-bin/fwupload.cgi using a multipart parsing flaw that stores /tmp/firmware.img, then triggers firmware validation via SOAP LoadFirmwareValidation. Authentication checks are flawed due to inconsistent allowlist/denylist logic, letting a request bypass unless the URI exactly equals /WEBCGI1/. This enables flashing and reboot, yielding RCE. Exploit can be LAN-only or remote with remote management enabled; Shodan shows MR2600s exposed. End-of-life device; disclosure pursued.

Prioritizing minimal computing, the author abandons GUI reference managers in favor of a single BibTeX file. After trying Zotero, JabRef, Cobib, and Tellico, he exports to BibTeX and uses the plain-text file as his sole manager for almost two years. Benefits: field types, keywords, and notes allow flexible organization; can grep to filter entries; portable, version-controlled, and Unix-friendly. Despite a steep TeX-related learning curve, BibTeX provides a durable, interoperable backend beyond front-end tools.

XBOX OG Adventures: a hobby project where the author ports a Vulkan-based Mirage engine to the original Xbox. He details battling obsolete SDKs and toolchains (C++98/03, cmake 1.4, VS 2003) and cross‑platform builds to run on OG Xbox and modern Windows. He converts a modern scene (Sponza) to Xbox formats (.x/.xbg) via OBJ and Maya/Blender steps, using RDFs for textures. The piece covers animation methods (vertex blending vs tweening) and shader needs, and even backports Unreal Engine 6’s Quinn to OG Xbox, ending as a reminiscence of early Xbox development.

Maria, a Brazilian domestic worker, was rescued in Fortaleza at 62 after 55 years of enslaved, wage-free, vacation-free labor across three generations. She started at age seven and lived in near-total isolation with no literacy. The Labor Prosecutor’s Office led the operation; the family agreed to compensate her and buy a $30,000 fully furnished apartment plus $10,000 in additional compensation. Maria will remain with the employers for now as authorities locate her family. Prosecutors also allege possible Bolsa Família fraud by the family.

Terence Tao describes reviving and extending his math applets by porting old Java applets to JavaScript with AI assistance. The port restored functionality of visualizations (Besicovitch sets, honeycomb, Allen Knutson collaboration) and added color upgrades; the AI found bugs Tao hadn’t noticed, with only one minor drag issue. Encouraged, he used AI to develop a new Minkowski-space visualization for special relativity. He also produced a Gilbreath conjecture visualization to accompany a paper/blog post. Tao plans more AI-assisted interactive visualizations as non-critical supplements, tolerating some risk.

Microsoft, Amazon and Google’s combined emissions rose 25% in the year to March 2026 to 119 million mTCO2e, about a third of France’s emissions, driven by datacentre expansion for cloud and AI. Microsoft up 25% to 20m mTCO2e; Google 18%; Amazon 16% (20% in its supply chain). Critics warn that cloud growth shifts footprints and carbon credits are scarce. The datacentre boom could consume about 1.3% of global electricity, with ~1,200 new datacentres expected by 2030 (mostly in the US). All three maintain net-zero targets for 2030–2040.

An Incogni study finds 55% of Americans say maintaining an online presence feels like work, driving reduced posting amid noise and politics. Gen Z feels the workload most (~60%), Boomers least (~38%). Many would quit due to security concerns, harassment, wasted time, and doomscrolling; 44% say political content drives people away. Most now post less or are more selective, with some willing to quit entirely. Advice: trim toxic connections, focus on real friends, and use security tools.

Multisite autopsy study of 74 decedents ≥60 days after SARS-CoV-2 infection examined left ventricular tissue. SARS-CoV-2 reverse strand (viral replication marker) detected in 11 cases (V+). Cardiac Long COVID (CLC) present in 9/11 V+ vs 23/63 V- (p=0.0075). V+ hearts showed greater remodeling (higher heart-weight/LV-wall-thickness, LV dilatation) and more pericardial effusion; shorter interval since infection; higher prevalence of severe acute COVID. ISH confirmed viral spike strand in myocytes. Transcriptomics revealed 44 altered genes, notably IRF4. Conclusion: cardiac viral persistence may drive CLC pathology and guide diagnostics/therapies.
