An anonymous reader quotes a report from Ars Technica: Microsoft's Build developer conference kicked off today, and as with almost everything the company has done in the last few years, Microsoft's opening keynote focused overwhelmingly on AI and other closely related technologies. [...] On the hardware front, we didn't get any updates for existing Surface devices (not counting yesterday's Surface Laptop Ultra announcement), but we did get something new: the Surface RTX Spark Dev Box is "a compact developer PC" built around Nvidia's new RTX Spark chip with up to 128GB of built-in memory. The Dev Box looks a little like a cartoon anvil or piano fell onto an Xbox Series X and flattened it. Its aluminum casing was designed "to double as a heatsink," and its preloaded version of Windows 11 Pro will include a "purposeful" set of developer-centric default settings and preinstalled tools. This is a follow-up of sorts to the Windows Dev Kit 2023, also known as "Project Volterra." This Qualcomm Snapdragon 8cx Gen 3-powered PC was essentially the system board from a Surface Pro tablet stuffed into a plastic box, and it was introduced alongside Arm-native versions of several Microsoft developer tools. It helped to set the stage for the Arm-based flagship Surface devices that launched the next year, which benefitted from a better and faster x86-to-Arm code translation technology called Prism and a greater number of Arm-native third-party apps that didn't need to be translated in the first place. Microsoft didn't announce pricing or specific specs for the RTX Spark Dev Box, but you can probably expect it to cost quite a bit more than the $600 that Project Volterra did. Hopefully, Microsoft can keep the price at least somewhat lower than the $4,699 asking price for Nvidia's similarly specced DGX Spark box. On the software side, several developer-centric changes are coming to Windows 11, particularly for users of the Windows Subsystem for Linux (WSL). Microsoft is introducing a Windows-native version of the coreutils command line tools, so that commands or scripts made for Linux work within Windows and the other way around; the ability to run WSL inside of containers, said to be arriving in "the coming months"; and something called Windows Developer Configurations that uses the WinGet tool to quickly set up "a distraction-free dev environment with VS Code, GitHub Copilot, WSL, PowerShell 7 and developer-optimized settings with one command on any Windows 11 device." Microsoft also introduced Microsoft Execution Containers (MXC), as "enterprise-grade sandboxed environments" that let AI agents like OpenClaw operate on Windows without getting unrestricted access to the whole system. In theory, MXC could let organizations enforce agent-specific limits, such as blocking access to personal accounts, separating work and personal data, or requiring permission before deleting files. The MXC GitHub repo also notes support for "multiple containment backends," meaning the same sandboxing concept could apply beyond AI agents to other plugins, tools, and workloads.
