New API Corrects China's Adjusted Workdays
The article explains that mainstream holiday APIs (Calendarific, HolidayAPI.com, Abstract API, Nager.Date) return only official Chinese holidays and miss China's adjusted weekend workdays (调休补班). Using the State Council notice for 2026 (Nov 4, 2025), the author demonstrates that several 2026 weekend dates (e.g., 2026-02-14) are officially designated workdays. To address this, the author published a Global Holidays API on RapidAPI covering 501 countries and explicitly including China's adjusted workdays, sourced from State Council notices and manually maintained. The post includes usage examples, feature comparisons with competitors, and pricing tiers (free and paid plans).
A niche product launch that fixes a regional holiday-data gap (China adjusted workdays); useful for scheduling, attendance, logistics, and delivery systems but not industry-shifting for AdTech broadly.

Key Takeaways & Evidence Grounding
- Mainstream holiday APIs (Calendarific, HolidayAPI.com, Abstract API, Nager.Date) typically return only official public holidays and do not handle China's adjusted workdays (调休补班).
- China's 2026 holiday schedule (cited from a State Council notice dated 2025-11-04) lists multiple adjusted weekend workdays, including 2026-02-14 as a workday.
- The author published a Global Holidays API on RapidAPI that covers 501 countries/regions and includes China's adjusted workdays as exclusive data, maintained from official State Council notices.
- Global Holidays API pricing tiers include a free plan (1,000 requests/month) and paid plans: Pro $10/month (10,000 requests), Ultra $25/month (50,000 requests), Mega $100/month (500,000 requests).

Microsoft Unveils Hybrid Intelligence, Open-Weight AI, RTX Hardware
Microsoft is repositioning Windows as a platform for 'hybrid intelligence,' enabling AI agents to run locally on PCs or in the cloud. The company announced the general availability of Microsoft Execution Containers (MXC), which sandbox agent execution and control access to files and networks, with support from Codex, GitHub Copilot, OpenClaw, and others. New AI models, including Microsoft's MAI Code 1.1 Flash, Nvidia's Nemotron, and DeepSeek V4 Flash, will run locally on RTX Spark devices, including the Surface Laptop Ultra (available for pre-order at $2,599). Copilot is gaining access to local files and system actions on Copilot+ PCs, rolling out in the coming months. Microsoft is diversifying its AI partnerships beyond OpenAI, building its own models, and aiming to regain trust after past missteps by emphasizing security and on-device processing.
Stacklok Brings Agent Harnesses to the Cloud
Stacklok, founded by Kubernetes creators Craig McLuckie and Joe Beda, is pivoting from software supply chain security to Kubernetes-based agentic solutions. They are developing Mecatl, a cloud-native agent harness, and ToolHive, an open-source platform for managing MCP servers. The company aims to help enterprises run and govern AI agents centrally, reducing dependence on frontier labs and hyperscalers. The commercial product is an 'enterprise spine' offering identity, authorization, policy, and auditing. Stacklok raised a $17.5M Series A in 2023. The article discusses the challenges of moving agent loops to the cloud and the company's vision for enterprise governance of agent interactions.
Coding Agents Boost Code Production but Not Project Delivery
A guest article by Markus Kirchmaier of LEAN-CODERS argues that while AI coding tools significantly increase code production, they do not proportionally accelerate software project completion. Citing a 2026 Management Science study showing a 26% increase in developer tasks with AI support, and an NBER study with over 500,000 GitHub developers showing up to 240% more coding activity with autonomous coding agents, only about 30% of that translates to actual releases. The article highlights that generated code still requires human review, testing, and maintenance, and that organizational factors like requirements gathering, approvals, and dependencies are not accelerated by AI. The author calls for measuring actual release speed rather than developer hours saved, citing a quote from Christoph Ott, founder of LEAN-CODERS, questioning if developers were ever the bottleneck.
