How an AI agent can connect to Tekmetric and what shops should keep under human control

An AI agent can reach Tekmetric data either through a Tekmetric-approved app that a shop admin authorizes in Shop Settings, or through a webhook an admin sets up directly. Tekmetric already offers texting, automated reminders, and campaigns, but these run on fixed rules and do not weigh context such as a customer's past questions or unanswered estimates. An agent would instead flag gaps like unanswered estimates, declined work, and finished vehicles awaiting pickup, then draft follow-up messages. Every drafted message would need a service advisor's approval before it reaches a customer. A third-party review says API credentials are not self-serve and can take two to three weeks to be approved.

Arbitrum Bridge TVL Rises to $3.5B; Analysts Flag Moderate-High Liquidity Risk

A technical security report assesses the Arbitrum Bridge, which holds roughly $3.52 billion in total value locked, up about 4.2% over 30 days and 12.7% over 90 days. Around 84% of that value sits in canonical custodial contracts, with the remainder spread across user escrow contracts and third-party liquidity providers. The analysis rates the bridge's overall risk moderate-high, at 6.8 out of 10, citing economic attacks such as mass exits and governance-related upgrade risks rather than code-level flaws. The main vectors identified include fraud-proof exploits, sequencer collusion, governance upgrade attacks, and AMM-manipulation-driven liquidity drains.

Loreflow Designs Its AI Answer Pipeline to Structurally Block Three Data Leak Types

Loreflow describes an answer pipeline built so that cross-tenant data leakage cannot happen regardless of model behavior. Its evidence-projection module is a pure function with no database handle, request context, or logger, so a bug can degrade answer quality but cannot reach another tenant. To limit prompt-injection risk from retrieved text, answers are assembled under fixed evidence budgets, and retrieved content is labeled as evidence rather than instructions. The team also prohibits object spreading when building evidence, so each field visible to the model must be explicitly listed, preventing internal fields from leaking silently.

Hysteria2 VPN connections stalled after upload speed tests; a 37-line fix followed

The developers of Colitu, a VPN with open-source apps, use the QUIC-based Hysteria2 transport, which their clients prefer on many networks. Their apps run health checks and switch to a TCP backup when the primary transport stops responding, but Hysteria2 kept being declared dead during speed tests. Captured traffic showed the QUIC connection was still alive while no new stream data was sent, pointing away from the network and toward flow control. Tests ruled out ISP shaping, congestion control, a QUIC mimicry mode, and stream limits as causes. Reproduction on a loopback setup showed the stall occurs when the upload's destination stops reading while its connection remains open, consistent with QUIC's per-stream and per-connection limits on unread data.

Developer Releases Open-Source Python CLI That Generates Clean Architecture NestJS Modules

A developer has built a Python command-line tool that generates production-grade NestJS backends following Clean Architecture, DDD, and CQRS from a single YAML file. The generator produces domain logic, CQRS handlers, TypeORM persistence, validated DTOs, Swagger documentation, and REST controllers for each entity. The author argues that clean architecture is maintainable but its repetitive folder and file setup is tedious, so automating it yields consistent structure and fewer bugs. The tool is open-source and available on PyPI, and the article also describes how its architecture is designed.

ListLens Uses Open-Weight AI to Write Etsy and eBay Listings From Product Photos

ListLens is a new tool built for Etsy and eBay sellers that generates complete listings from one to eight product photos. It produces a title, description, tags, and category tailored to the chosen platform, aiming to cut the typical 15 to 20 minutes per listing down to about 15 seconds. The app runs on open-weight models rather than closed APIs, with a vision model first extracting only clearly visible attributes and a second model writing the copy. Its developer says this two-step split helps limit hallucinated details that could violate platform authenticity rules. The project was submitted to a Hacktoberfest open-source AI challenge and is hosted on Vercel.

US Agencies Warn of Knowledge Distillation Campaigns Using LLM API Gateways

NSA, CISA and the FBI issued advisory AA26-251A describing large-scale knowledge distillation campaigns that extract model capabilities through native APIs, cloud providers, third-party aggregators and proxy relays. The article argues that self-hosted LLM API gateways, which front multiple upstream models, are a likely chokepoint and that organizations should first locate such systems on their own networks. It notes that asset search engines like ZoomEye can find gateway panels, such as those from the New API project, by their banners or titles. The advisory recommends detection and mitigation, targeted response changes and cross-organization intelligence sharing. The author cautions that a detected panel shows software presence only, not confirmed misuse or compromise.

MCP Emerges as a Common Standard for Connecting AI Agents to Tools

Model Context Protocol (MCP) is gaining traction as a shared standard for how AI agents connect to external tools and data. Developers currently build separate, one-off integrations for each tool, which makes systems fragile and hard to maintain. MCP proposes a common wire format, a discovery mechanism that lets agents list available tools, and a unified permission model. The article recommends starting with narrow, read-only MCP servers for specific domains, adding human approval for write actions, and versioning servers like any other API. Adopting such a standard could make it easier to swap tools or agent frameworks without rebuilding integrations.

Fewer crates.io projects go silent on outside pull requests than npm or PyPI

A Porchlamp analysis of open-source projects found that 20.0% of decided crates.io projects are "black holes", meaning they leave most outside pull requests without a human reply, review, or merge for two weeks. By comparison, the figure is 30.0% for npm and 33.8% for PyPI, based on a snapshot taken on 14 October. The Rust subset covers 1,065 crates.io projects, and across all six ecosystems studied, 26.4% of decided projects are black holes. The author cautions that the results are a single snapshot without controls for project size, which correlates with black-hole rates, and that undecided projects are excluded from the percentages.

BIPM to abolish leap seconds from 2025, prompting infrastructure timing changes

The International Bureau of Weights and Measures has decided to stop inserting leap seconds starting in 2025, turning UTC into a linear time scale aligned with TAI. The decision has triggered a surge in online searches and debate among system administrators, IoT developers and high-frequency traders. Systems that still assume the clock may skip or repeat a second risk failures in data pipelines, trade ordering and telecom sessions. The article outlines required adjustments for NTP, PTP, databases, Java applications, scripts and IoT firmware, along with compliance policy updates. It also notes that past leap-second insertions caused outages in 2012 and 2015, underscoring the importance of the transition.

BIPM Decision to Drop Leap Seconds Prompts IT Teams to Update Time Systems

The International Bureau of Weights and Measures has decided to eliminate leap seconds from UTC, with the change becoming mandatory on 1 January 2027. Instead of periodic inserted seconds, UTC will gradually drift from TAI at roughly 0.9 seconds per year, from a current offset of 37 seconds. Organizations such as financial exchanges, telecom operators, and IoT device makers are reconfiguring NTP, PTP, and other time services to use a deterministic UTC-TAI offset rather than relying on leap-second events. The shift is driven by the risk that unexpected 61-second minutes could corrupt databases and breach regulatory timestamp accuracy requirements. Industry interest has surged, though many systems, particularly low-power devices, may not yet be prepared.

Guia sobre a pirâmide de testes e os níveis de teste de software

O texto apresenta a pirâmide de testes como forma comum de organizar os níveis, com mais testes na base e menos no topo. Os níveis de base, como unidade e integração, tendem a ser automatizados via API ou código, enquanto os de topo, como sistema e aceite, usam interface gráfica e são mais lentos e frágeis. A ideia central é antecipar a garantia de qualidade, o chamado shift-left, com ambientes que se aproximam mais da produção conforme se sobe na pirâmide. Cada nível responde a uma pergunta específica, da funcionalidade isolada de uma unidade até a adequação do sistema ao problema de negócio. Por fim, a integração costuma se dividir em pelo menos dois níveis, o de componentes e o de sistema.
