Review: Building Machine Learning Systems with a Feature Store

Many people come to machine learning by training a model on a tidy dataset, and then meet a harder problem: making that model work for real users, on fresh data, every day. Jim Dowling’s O’Reilly book, Building Machine Learning Systems with a Feature Store, is written for that moment. Dowling, CEO of Hopsworks, based the book on a course he taught at KTH in Stockholm, so it reads like a guided walk through building real … More → The post Review: Building Machine Learning Systems with a Feature Store appeared first on Help Net Security.

Your company already adopted AI and nobody is governing access

In this Help Net Security video, Antoine Berton, CTO at Elba Security, breaks down the AI attack surface. Your company already adopted AI, and every adoption creates access that nobody governs. A quick click on a Friday afternoon connects a free AI tool to your Google Workspace, with no ticket and no security review. Berton maps five places where exposure lands, from standing OAuth grants and copilots that inherit human permissions to agent credentials stored … More → The post Your company already adopted AI and nobody is governing access appeared first on Help Net Security.

AI just supercharged the race to find room temperature superconductors

Scientists have combined machine learning with quantum physics to discover two new superconductors and create a much faster way to search for many more. The technique could bring researchers significantly closer to the long-sought goal of a room-temperature superconductor.

Apple Container: Open-source tool for Linux containers on the Mac

Developers on Apple silicon Macs have run Linux containers through software built around a single shared virtual machine for years. Apple’s open-source Container project gives each Linux workload its own lightweight virtual machine. Container is written in Swift and tuned for Apple silicon. It creates and runs Linux containers as lightweight virtual machines, and it works with OCI-compatible images, so a developer can pull from and push to any standard registry. Images built with it … More → The post Apple Container: Open-source tool for Linux containers on the Mac appeared first on Help Net Security.

Microsoft wants to keep your AI agents from going rogue

Microsoft has introduced Microsoft Execution Containers (MXC), a cross-platform, policy-driven execution layer for AI agents on Windows and Windows Subsystem for Linux (WSL), now available in early preview. Updated Agent 365 platform (Source: Microsoft) Developers can define constraints for their applications and agents, and Windows enforces them at runtime through MXC. The SDK provides an abstraction layer over isolation primitives, eliminating the need for developers to manage low-level isolation details. “Containment bounds what agents can … More → The post Microsoft wants to keep your AI agents from going rogue appeared first on Help Net Security.

Power shortages could slow AI data center expansion

AI adoption is increasing demand for data center capacity at the same time operators are running into limits around power, equipment, land, and permitting, according to NTT Data. Access to electricity is becoming a deciding factor in where new data centers are built, when new capacity comes online and how quickly AI projects can expand. Distribution of new data center capacity by region (Source: NTT Data) AI changes infrastructure planning Enterprise workloads spread computing demand … More → The post Power shortages could slow AI data center expansion appeared first on Help Net Security.
