    MacPaw Research argues that computer-use AI systems underperform on macOS because public training datasets contain almost no Mac interface data. Their new open-source project, GUIrilla, addresses this by automatically exploring macOS applications and generating structured UI datasets at scale. The release includes GUIrilla-Task, a dataset covering over 1,100 Mac apps and 27,000 tasks, plus macapptree, a Python library for extracting accessibility metadata from Mac applications. Together, these tools aim to improve AI agents, UI understanding models, and developer tooling across the Mac ecosystem.

    LangChain built SmithDB, a purpose-built distributed database in Rust that now powers LangSmith's agent observability. Modern AI agent traces have gotten too big and complex for general-purpose databases, with hundreds of nested spans, multi-modal content, and spans that stay open for hours. SmithDB uses an object-storage-backed LSM architecture built on Apache DataFusion and the Vortex file format, delivering P50 latencies of 92ms for trace tree loads and making LangSmith up to 15x faster. It is not a standalone product you install; it is the new data layer behind LangSmith, and it is already serving 100% of US Cloud ingestion and tracing UI traffic.

  • What to Look For in a Free VPN

    Free VPNs can improve security on public Wi-Fi, but not all are trustworthy. Here’s how to evaluate privacy, encryption, limits, and safety.

    Free VPNs can help secure browsing on public Wi-Fi, but they are not all equally safe. Before downloading one, users should review logging policies, encryption standards, data limits, permissions, and business models. Some free VPNs collect or share user data, while others limit speed or streaming access. For sensitive work, banking, gaming, or heavy streaming, a paid VPN may offer stronger protection and reliability.

  • The Greenfield of Agentic Payments. Cross-Network Settlement is Still Up for Grabs.

    This story was originally published on HackerNoon at: https://hackernoon.com/the-greenfield-of-agentic-payments-cross-network-settlement-is-still-up-for-grabs.


    Agentic payments are growing, with SODAX positioning itself as the infrastructure partner for applications to build agentically across blockchain networks.

    Consensus Miami 2026 made one thing clear: AI agents are about to drive up to $5T in commerce by 2030, and the race to power agentic payments is on. x402, Google's AP2, Stripe's MPP, Visa Intelligent Commerce Connect, and Mastercard Agent Pay are all fighting to own the agent-to-merchant checkout moment. But what happens when an agent needs to rebalance, repay, or move value across blockchain networks. Settlement is still up for grabs. SODAX SDK v2 (live May 2026, spans 18 networks, agent-readable docs), is building the execution system for cross-network settlement. Handing builders the tools to deploy and run their application at pace, with agent workflows in mind.

  • AVIAN Raises $2.6M to Turn Industrial Risk Into Data Opportunity the Insurance Market Can Underwrite

    This story was originally published on HackerNoon at: https://hackernoon.com/avian-raises-$26m-to-turn-industrial-risk-into-data-opportunity-the-insurance-market-can-underwrite.


    Zurich-based AVIAN raises $2.6M led by Founderful to scale 24/7 thermal monitoring across sawmills, recycling, chemicals and oil & gas.

    What does AVIAN do?
    AVIAN provides always-on AI thermal monitoring at industrial sites to detect fire and equipment-failure risk before incidents occur. The platform combines continuous thermal cameras, plant-specific baseline learning, smart alarm filtering, automated predictive maintenance reports, and 24/7 human review.
    How much has AVIAN raised?
    AVIAN raised a $2.6 million pre-seed round in May 2026, led by Founderful. The company was profitable and bootstrapped for two years before the round.
    Who are AVIAN's customers?
    AVIAN is deployed across roughly 50 sites in 9 countries. Named customers include Kamps Pallet (Dillwyn, Virginia), Sierra Pacific Industries (Quincy), and Schilliger Holz, one of the largest sawmills in Switzerland.
    Why are industrial sites becoming uninsurable?
    Industrial fire and downtime losses have risen sharply over the past decade. Fire and explosion are the single largest driver of corporate insurance losses by value, with over EUR 18 billion in insured losses across the past five years per Allianz. Reinsurance hardening has pushed property reinsurance rates up by as much as 200 percent on catastrophe lines since 2023, forcing primary insurers to re-rate aggressively or stop writing the riskiest accounts.
    How is AVIAN different from traditional thermography?
    Traditional industrial thermography is periodic. A technician walks the floor with a handheld camera once a quarter. AVIAN is continuous. The platform learns each plant's thermal baseline and detects drift in the hours before a component ignites combustible material around it.
    What is AVIAN's long-term thesis?
    Industrial risk has been priced for decades using actuarial tables and historical claims data. AVIAN's bet is that the next decade will be priced using real-time operational data, and that uninsurable sites can become insurable again when the data layer is in place.
