Discord has open-sourced Osprey, a scalable event stream decisions engine that processes 2.3 million rules per second. Osprey is designed for real-time threat detection and mitigation, and is built with a Rust coordinator and stateless Python worker nodes. The engine evaluates JSON-formatted event payloads against dynamically loadable rules written in a domain-specific language called SML.

Autonomous vehicles rely on complex software stacks that require optimization to manage resources, time, and physics constraints. Techniques such as context-aware sensor prioritization, Model Predictive Control (MPC) solvers, and real-time compute budgeting enable safe and efficient operation.

The article discusses seven key learnings for getting companies to adopt AI, including buying models directly, raising the ceiling for AI usage, and providing support for AI-forward employees. It also highlights the importance of flexibility, cutting-edge technology, and cost-effectiveness in AI adoption.

Rebellions, a South Korean AI chip startup, has raised $400 million in a pre-IPO round, valuing the company at $2.3 billion. The funding will be used to expand its presence globally, particularly in Asia, the Middle East, and the US. Rebellions develops AI chips for inference and has released two new products: RebelRack and RebelPOD.

Qodo, a startup building AI agents for code review, testing, and governance, has raised $70 million to improve trust in AI-generated code. The company aims to serve as a layer focused on improving trust in AI-generated code as enterprises accelerate adoption of tools like OpenClaw and Claude Code.

The demand for AI acceleration is driving new approaches to measuring greenhouse gas emissions. Experts discuss the need for continuous measurement, component-based metrics, and sustainability in AI infrastructure. This includes understanding the environmental impact of each component, tracking data usage, and implementing automation to reduce waste.

Bluesky's new app Attie is an AI assistant that lets users build their own algorithm and create custom feeds using natural language. It's powered by Anthropic's Claude and built on top of Bluesky's AT Protocol. Attie will eventually allow users to vibe-code their own apps on top of atproto.

OpenAI has restructured into a for-profit and nonprofit arm, raising concerns about its mission to serve humanity. The nonprofit arm will guide the for-profit side, but critics argue this structure is untenable and prioritizes profits over the mission.

Bluesky has launched an AI assistant called Attie, allowing users to design their own social media algorithms. However, the response has been negative, with 125,000 users blocking Attie's account, making it the second most blocked account on the network. The backlash is due to concerns about AI's encroachment into social media and the platform's priorities.

Mantis Biotech is developing a platform to create 'digital twins' of humans, which can be used to simulate and predict medical issues, study rare diseases, and train AI models. The company's platform integrates disparate data sources and uses a physics engine to create high-fidelity models of the human body. This technology has the potential to solve the data availability problem in medicine and can be used in various fields such as professional sports and preventative healthcare.

Rebellions, a South Korean AI chip startup, is expanding its reach beyond its home market with a new rack-scale compute platform. The company's Rebel100 chip uses a chiplet architecture and is capable of a petaFLOP of dense 16-bit floating point math. The platform is designed to be air-cooled and can be deployed in existing enterprise datacenters, making it a more accessible option for companies looking to adopt AI technology.

Microsoft's Fabric Database Hub is a new tool that allows administrators to manage multiple Microsoft database services from a single location. It supports services like Azure SQL Server, Azure Cosmos DB, and Azure Database for PostgreSQL. While it can make database management more connected and manageable, its limitation to Microsoft databases and DBaaS may not make it a comprehensive solution for enterprises with diverse database portfolios.

Mistral AI has raised $830 million in debt to build a new data center near Paris, which will be powered by Nvidia chips. The company plans to complete the data center in the second quarter of 2026 and aims to deploy 200 megawatts of compute capacity across Europe by 2027.

Starcloud, a space compute company, has raised $170 million in Series A funding to build data centers in space. The company aims to launch a more powerful version, Starcloud 2, later this year and is developing a data center spacecraft, Starcloud 3, designed to launch from SpaceX's Starship. Starcloud's goal is to provide cost-competitive data centers in space, with costs on the order of $0.05 per kilowatt-hour of power.

Adobe's new Turntable tool in Illustrator uses AI to generate multiple angles of a 2D image, up to 74 views, while keeping them editable as vectors. This saves hours of work and opens up new possibilities for 2D artists to explore 3D techniques without leaving Illustrator.

A critical F5 BIG-IP flaw (CVE-2025-53521) is being exploited by hackers to deploy webshells on unpatched devices. The vulnerability allows for remote code execution and has been flagged by CISA as actively exploited. Over 240,000 BIG-IP instances are exposed online, and users are advised to patch immediately.

GitHub has removed the ability of its Copilot AI tool to add ads to pull requests after backlash from developers. The ads, which were added to over 11,400 pull requests, were seen as intrusive and annoying. GitHub's product manager acknowledged that the decision to allow Copilot to edit pull requests was a 'wrong judgment call'.

SAP is acquiring master data management and data integration specialist Reltio to integrate external data into its AI platform, boosting its Business Data Cloud. The move aims to make BDC fully interoperable with other enterprise data stores, supporting AI agent development by cleansing and harmonizing data.

Check Point researchers found a flaw in ChatGPT that allowed data to be transmitted to an external server through a DNS side channel. OpenAI has since fixed the issue, which could have had serious implications for regulated industries that deploy AI services.

The European Commission has confirmed a cloud data breach, with hackers potentially taking data from its Europa.eu platform. The breach was discovered on March 24 and immediate steps were taken to contain it. Extortion group ShinyHunters claims to have compromised over 350GB of data, including sensitive material.
