Introduction TL;DR: Use Webhook triggers and normalize payloads early with Set, then process/merge/notify with minimal Code. Treat failures as first-class: Error Trigger + Error Workflow, and intentionally fail with Stop And Error when business rules break. Scale reliably with queue mode (Redis + Postgres), lock your encryption key, and enable metrics/audits for operations. In production, n8n isn’t about “making workflows run once.” It’s about building repeatable, observable automation around webhooks, error handling, batching, and scaling. ...

Introduction TL;DR: This post focuses on production-grade n8n self-hosting. We cover Docker Compose templates (single & queue mode), Postgres/Redis, reverse proxy TLS, webhook URL correctness, backups, and monitoring. In practice, most self-hosting incidents come from URL/webhook mismatch, lost encryption keys, and runaway execution data growth. We’ll harden those first. 1) Design decisions that matter in production n8n defaults to SQLite for credentials, executions, and workflows, and supports Postgres for self-hosted setups. n8n’s database environment variable docs also state that MySQL/MariaDB support was deprecated in v1.0, so Postgres is the safe default for new deployments. ...

Introduction TL;DR: OpenAI’s Vice President of Research, Jerry Tworek, is departing after nearly seven years to pursue types of research that he described as difficult to conduct within OpenAI. This announcement has drawn industry attention to leadership and research direction at major AI labs. OpenAI has been a leading force in advancing large-scale generative AI models, but recent shifts in leadership and departures of key researchers have sparked discussion about balancing commercial success with foundational research. ...

Introduction TL;DR: Data center construction for AI and cloud computing is increasingly blocked or delayed by local community opposition. The conflict is not abstract: it centers on measurable impacts—power, water, noise, visual/land use, and backup generation emissions—plus trust and transparency. Context (keywords): AI data centers, cloud computing, and local opposition are colliding as hyperscale buildouts try to land near latency-sensitive demand centers. Why it matters: If social acceptance becomes the gating factor, “capacity planning” must include permitting path, community data disclosures, and operational monitoring—not just GPUs and racks. ...

Introduction TL;DR: n8n is a workflow automation platform where you connect nodes starting from a trigger (schedule/webhook/event) and pass JSON “items” through the workflow. You’ll move fastest by learning (1) the items data model, (2) expressions like {{ $json... }}, and (3) operational basics: encryption key, webhook URL behind a proxy, and execution data retention. Core Concepts You Must Know Items and data flow n8n passes data between nodes as an array of JSON objects called items. Most nodes run once per item. ...

Introduction TL;DR: The U.S. is allowing limited exports of NVIDIA’s H200 to approved customers in China, adding a 25% fee and a U.S. security review step. (Reuters) Reuters reports strong China-side demand signals (orders and planned shipments), alongside supply-chain actions such as capacity discussions with TSMC. (Reuters) Context: In 2026 AI infrastructure, policy and logistics can be as determinative as raw GPU performance. (Federal Register) What Actually Happened: Not “Investment,” but Policy + Supply Chain Rewiring Reuters reports the U.S. will allow exports of NVIDIA’s H200 to China and collect a 25% fee, with shipments limited to approved commercial customers and subject to conditions framed around national security. The same Reuters report describes a process where chips route into the U.S. for security review before re-export to China. (Reuters) ...

Introduction TL;DR: Reports from early 2026 describe a Chinese hospital embedding an AI tool (PANDA) into routine non-contrast CT workflows to flag pancreatic tumors earlier. (ETEnterpriseai.com) The underlying research (Nature Medicine, 2023-11-20) positions PANDA as an “opportunistic screening” approach on non-contrast CT, with large-scale validation metrics published in the paper. (Nature) The hard part isn’t only model accuracy: low prevalence diseases demand careful false-positive and callback governance to prove clinical net benefit. (Nature) Why early pancreatic cancer detection is hard Pancreatic cancer has poor outcomes largely because it is often detected late. In the U.S., SEER reports an overall 5-year relative survival of 13.3% (2015–2021). (SEER) ACS, also based on SEER, lists an overall 5-year relative survival of 13% (diagnosed 2014–2020) and shows steep drops by stage (localized vs distant). (Cancer.org) Nature Medicine explicitly frames general-population screening as difficult due to low prevalence and harms from false positives. (Nature) ...

Introduction TL;DR Seed-Omni-8B refers to HyperCLOVA X SEED 8B Omni, a unified omnimodal model that supports text/image/audio (and video input) -> text/image/audio output. OmniServe provides an OpenAI-compatible inference API, and image/audio outputs are designed to be stored on S3-compatible storage and returned as URLs. A turnkey demo shared on NVIDIA Developer Forums (seed-omni-spark) helps you run it on DGX Spark with Docker Compose + MinIO + a WebUI. In this post, we’ll map the model’s capabilities, the serving architecture, and the fastest path to a hands-on demo. ...

Introduction TL;DR: Supermicro announced the 6U SuperBlade (SBI-622BA-1NE12-LCC) on 2025-12-31, positioning it for AI/HPC with air and direct liquid cooling options. The headline claims focus on rack-level efficiency: up to 93% cable reduction, up to 50% space savings, and up to 100 servers per rack (depending on rack assumptions). The key takeaway: AI infrastructure competition is expanding from chips to rack density + power + cooling + operations. 1) What was launched: 6U SuperBlade (SBI-622BA-1NE12-LCC) 1-1 Announcement facts (verifiable) Supermicro’s release (distributed via PRNewswire) describes the SBI-622BA-1NE12-LCC as a high-density blade server using dual Intel Xeon 6900-series processors (P-cores), supporting both air cooling and direct liquid cooling. ...

Introduction TL;DR: CES 2026 runs Jan 6–9, 2026 in Las Vegas, with official pre-show media events starting Jan 4. CTA’s official messaging puts AI, robotics, and digital health at the center, and the official CES App explicitly includes a new AI chatbot (“Ask AI”). Major previews (e.g., The Verge, Engadget) frame the show around AI-integrated laptops, wearables/health, smart home, and robots—signaling “AI integration” as a baseline expectation even before the show floor opens. CES 2026 at a glance: dates, pre-show, and official channels CES’ official pages list CES 2026 as January 6–9 in Las Vegas, NV, with a separate “Dates and Hours” schedule that includes Media Day programming starting Sunday, Jan 4 and continuing on Monday, Jan 5. ...
