CopilotKit Launches OpenBot, an Open-Source AI Agent Platform with Built-In Security

CopilotKit has released OpenBot, an open-source platform that deploys AI agents as autonomous coworkers within enterprise infrastructure using Docker Compose and PostgreSQL. Each agent operates inside an isolated Docker container with its own browser session and private workspace, preventing any interference with the host system. A central security gateway evaluates every command, file access, and web navigation request using Common Expression Language policies before execution, with all actions logged in a searchable audit ledger. When agents encounter high-risk situations such as two-factor authentication or CAPTCHAs, human operators can take over directly from the web interface before returning control to the agent. OpenBot supports multiple AI frameworks including LangGraph, CrewAI, and Pydantic AI through the open AG-UI protocol, and its source code is publicly available on GitHub.

Directory lists 29 developer and AI newsletters with verified subscriber counts for sponsors

A curated directory called devsponsors tracks 29 developer and AI newsletters available for sponsorship, including 25 on Substack and 4 self-hosted, with data current as of September 2026. The list distinguishes between Substack-stated subscriber counts and self-reported figures from independent newsletters, keeping the two categories clearly labelled and separate. Top newsletters by audience size include The Rundown AI at 1.7 million self-reported subscribers, Superhuman AI at 1.5 million, and TLDR AI at 1.1 million. Nine of the 29 newsletters publicly disclose their sponsors within issues, collectively naming 34 brands, with repeat buyers including Brilliant, CodeRabbit, and Unblocked each appearing three times. The directory also flags which issues are sent only to paying subscribers, since sponsored slots in paywalled editions reach significantly fewer readers than the total subscriber count implies.

How Enterprise RAG Systems Handle Large Data and Strict Access Control

Building a production-grade Retrieval-Augmented Generation (RAG) system for enterprise use requires solving two core challenges: managing large datasets efficiently and enforcing strict data access controls. Unlike basic RAG prototypes, enterprise deployments must break documents into smaller, metadata-tagged chunks to avoid overwhelming language models and reduce cost and latency. Security is enforced through Attribute-Based Access Control (ABAC), where every stored vector is tagged with ownership attributes so users can only retrieve data they are authorized to see. The proposed architecture combines FastAPI, PostgreSQL, Qdrant, and LangChain, keeping relational data and vector storage strictly separated for clarity and security. Access restrictions are applied deterministically at the database level, ensuring the underlying language model never processes data beyond a user's clearance.

By targeting this bottleneck, Cornelis hopes to improve overall AI compute performance and utilization.

How to Host a Static Website on Amazon S3 Without a Server

Amazon S3 can serve static websites directly from a storage bucket without requiring any EC2 instance or server management. To enable this, users must activate static website hosting under the bucket's Properties tab and define an index document and an optional error document. AWS blocks public access to all new buckets by default, so this setting must be manually disabled and a bucket policy granting public read access must be explicitly added. Once these steps are complete, the site becomes accessible to anyone via a dedicated S3 website endpoint URL. The exercise highlights a key AWS concept: an object existing in a bucket is not the same as that object being publicly reachable.

Jensen Huang Puts Trump on Speakerphone at All-In Summit to Dismiss AI Fears

Nvidia CEO Jensen Huang took a live call from President Trump while onstage at the All-In Summit on Monday, placing the call on speakerphone for the audience. Trump addressed growing public concerns about artificial intelligence, calling fears over the technology a 'hoax' and asserting that robots would not take over the world. It was not the first time Huang has received a call from the president during a public appearance.

Cloud Computing and AWS Basics: Key Concepts Every Beginner Should Know

Cloud computing delivers on-demand IT resources — including compute, storage, and networking — over the internet, fundamentally changing how infrastructure is provisioned and managed. Unlike traditional setups that require purchasing and maintaining physical hardware, cloud platforms allow organizations to provision resources quickly through web interfaces, APIs, or automation tools. Businesses adopt cloud infrastructure primarily for scalability, faster provisioning, and reduced upfront capital investment, though overall costs depend heavily on architecture and usage patterns. AWS organizes its global infrastructure into Regions and Availability Zones, and understanding this structure is essential for designing reliable cloud environments. The article outlines seven foundational AWS services recommended for beginners, emphasizing that cloud literacy is valuable beyond engineering roles alone.

How Webruno Built a Flexible React-Based Visual Page Editor Architecture

Webruno, a visual website builder platform, faced significant engineering challenges in designing a flexible and reliable page editor using React. Rather than storing raw HTML, the team chose to save structured JSON representations of pages, making components reusable and layouts easier to manage. A central component registry maps each element to its React implementation, allowing new components to be added without breaking existing websites. The architecture also handles responsive behavior at the component configuration level and includes data migration strategies to prevent old customer pages from breaking after platform updates. Additionally, the structured page format enables AI to generate website layouts by suggesting component arrangements, with the platform controlling the final rendered output.

Developer builds free browser-based room planner using OpenAI Codex and React

A developer has created Small Room Planner, a free browser tool that lets users design furniture layouts in 2D and preview them in 3D without requiring a signup. Built with Astro, React, TypeScript, SVG, and Three.js, the tool stores all edits locally in IndexedDB unless the user chooses to share a snapshot. OpenAI Codex was used throughout development for implementation and debugging, with the workflow centered on small iterative cycles guided by an AGENTS.md constraints file. Key technical lessons included separating stored measurements from visual rendering, collapsing furniture-drag events into single undo steps, and loading the 3D preview only on demand. The project is still in early stages, with the developer currently focused on improving the first-time user experience after observing low engagement from initial visitors.

Developer builds macOS menu bar app to control Soundcore headphones via Bluetooth

A developer spent a single weekend building SoundcoreBridge, a native macOS menu bar app that enables direct control of Soundcore Space 2 headphones without relying on the official mobile app. The project involved reverse-engineering the headphones' Bluetooth RFCOMM protocol by analyzing HCI snoop logs to decode command structures for noise cancellation, EQ, and battery readings. A key discovery was a mandatory handshake sequence the device requires before accepting any write commands — without it, all writes are silently discarded. The developer also found that the official Soundcore app displays cached values rather than live device state, causing it to show incorrect ANC levels after external changes. The finished app is open-source under the MIT license and is available on GitHub, supporting macOS 13 and above.
