Openvid: Open-Source Browser Tool Turns Screen Recordings into 3D Product Demos

·1 views

Developer Cristian Olivera has released Openvid, a free, open-source, browser-based video studio aimed at software developers and product creators. The tool converts plain screen recordings into cinematic product walkthroughs with 3D camera movements, device mockups, and professional-grade exports up to 4K at 30fps. It runs entirely client-side using WebAssembly (FFmpeg.wasm), Three.js, and IndexedDB, meaning video files never leave the user's machine. Openvid supports MP4, WebM with alpha transparency, and GIF formats, and wraps recordings in browser or mobile device frames. The project is publicly available on GitHub and can be tried live at openvid.dev.

How to Build a Reliable Telegram Post Monitor Using Apify and n8n

A developer tutorial explains why a scheduled scraper alone cannot detect new Telegram posts without a separate state-tracking layer. The core problem is that 'new' requires comparing the current data snapshot against a previous one — information a single Actor run does not hold on its own. The author built a solution using a stateless Apify Actor for scraping and an n8n workflow to manage comparison state, duplicate prevention, and first-run policy. Testing across four scenarios revealed that a fresh session with no baseline can retrieve posts but cannot determine which are new — a distinction the system must explicitly preserve. The design is presented as reusable for price trackers, job monitors, inventory checks, and any workflow that repeatedly asks what has changed.

Developer Seeks Contributors for Open-Source Post-Apocalyptic MMORPG Built in Rust and Python

A developer has launched an open-source MMORPG project called The Last Signal, a post-apocalyptic multiplayer game being built using Rust for server and networking components and Python for the client and tooling. The project is still in early development, with current work focused on client-server communication, packet handling, automated testing, and CI/CD pipelines. The developer is actively seeking contributors across several areas, including networking, server architecture, documentation, and experimental cryptography, which is described as not production-ready. Entry-point GitHub Issues have been created to help new contributors get involved without requiring deep prior knowledge of the codebase. Those with interests in Rust, Python, security research, or technical writing are particularly encouraged to participate.

Scaling AI Fails Without the Right Organisational Model, Experts Warn

While deploying AI has become faster and more accessible, many organisations struggle to convert short-term experiments into lasting capability. A 2026 Deloitte report found that nearly three-quarters of technology leaders expect their operating model to change within 12 to 18 months, highlighting a gap between deployment confidence and organisational readiness. Experts argue that AI scales not through technology alone but through a structured operating model covering decision rights, ownership, governance, delivery, capability-building, and feedback loops. Without such a model, independent team pilots often lead to fragmented tools, inconsistent data handling, and successful experiments that never become repeatable practice. The core challenge has shifted from asking whether AI can be used to whether an organisation can absorb and sustain it responsibly.

Three-Step Python Testing Framework Aims to Automate Agent Patch Verification

A software testing approach published on DEV Community outlines a three-rung verification ladder designed to validate AI-generated code patches using a single command. The framework combines seeded property checks via Hypothesis, fixture contracts for schema validation, and a time-limited quarantine system for flaky tests. Property tests are emphasized over example-based tests because AI patches often alter boundary behavior that fixed examples fail to catch. Fixture contracts act as lightweight schemas that run before domain tests, ensuring real data examples conform to defined rules. The TTL quarantine system automatically re-enables skipped flaky tests after a set deadline, preventing indefinite suppression of test failures. The article was disclosed as part of outreach for a product called MonkeyCode, with all components requiring only pytest and Hypothesis as dependencies.
