Netflix has open-sourced an AI framework that can remove objects from videos and automatically adjust the physical effects those objects had on the rest of the scene. The system is called VOID, short for "Video Object and Interaction Deletion." What makes it special is that beyond erasing objects from a scene, it also handles the downstream physical effects, like collisions, that the removed object originally caused.
VOID is built on top of Alibaba's CogVideoX video diffusion model, fine-tuned with synthetic data from Google's Kubric and Adobe's HUMOTO for interaction detection. Google's Gemini 3 Pro analyzes the scene and identifies affected areas, while Meta's SAM2 handles segmenting the objects that need to be removed. An optional second pass uses optical flow to correct any shape distortions.
The project was developed by Netflix researchers in collaboration with INSAIT Sofia University. Code, paper, and demo are available on GitHub, arXiv, and Hugging Face. The system ships under the Apache 2.0 license, which means it can be used commercially.

Hackers breached the European Commission by poisoning the security tool it used to protect itself
CERT-EU has attributed a major data breach at the European Commission to cybercrime group TeamPCP, which exploited a supply chain attack on the open-source security tool Trivy to steal 92 GB of compressed data from the Commission’s AWS infrastructure. The notorious ShinyHunters gang then published the data, which included emails and personal details from up [ ] This story continues at The Next Web

How to Clean Up Xcode and Free 30-50GB on Your Mac
Xcode is the single biggest storage consumer on most developers' Macs. A fresh install starts around 35GB, but over months of development it quietly grows to 80, 100, even 150GB+. Most of that growth is invisible — cached build products, old simulators, debug symbols for iOS versions you no longer use. I've been building iOS apps for years, and this problem is exactly why I built MegaCleaner — I got tired of manually tracking down these hidden folders every few months. But whether you use a tool or do it by hand, you should know where the space goes. This guide covers every Xcode storage category: what it is, where it lives, how big it typically gets, and whether it's safe to delete. No guesswork, no vague advice — just exact paths and clear safety levels. Quick Reference Before we dive in
