"You can use any Linux distribution inside of the Windows Subsystem for Linux" Microsoft recently reminded Windows users, "even if it is not available in the Microsoft Store, by importing it with a tar file." But being an official distro "makes it easier for Windows Subsystem for Linux users to install and discover it with actions like wsl --list --online and wsl --install," Microsoft pointed out this week. And "We're excited to announce that Red Hat will soon be delivering a Red Hat Enterprise Linux WSL distro image in the coming months..." Thank you to the Red Hat team as their feedback has been invaluable as we built out this new architecture, and we're looking forwards to the release...! Ron Pacheco, senior director, Red Hat Enterprise Linux Ecosystem, Red Hat says: "Developers have their preferred platforms for developing applications for multiple operating systems, and WSL is an important platform for many of them. Red Hat is committed to driving greater choice and flexibility for developers, which is why we're working closely with the Microsoft team to bring Red Hat Enterprise Linux, the largest commercially available open source Linux distribution, to all WSL users." Read Pacheco's own blog post here. But in addition Microsoft is also releasing "a new way to make WSL distros," they announced this week, "with a new architecture that backs how WSL distros are packaged and installed." Up until now, you could make a WSL distro by either creating an appx package and distributing it via the Microsoft Store, or by importing a .tar file with wsl -import. We wanted to improve this by making it possible to create a WSL distro without needing to write Windows code, and for users to more easily install their distros from a file or network share which is common in enterprise scenarios... With the tar based architecture, you can start with the same .tar file (which can be an exported Linux container!) and just edit it to add details to make it a WSL distro... These options will describe key distro attributes, like the name of the distro, its icon in Windows, and its out of box experience (OOBE) which is what happens when you run WSL for the first time. You'll notice that the oobe_command option points to a file which is a Linux executable, meaning you can set up your full experience just in Linux if you wish.

Red Hat, the IBM-owned open source software firm, is acquiring Neural Magic, a startup that optimizes AI models to run faster on commodity processors and GPUs. From a report: The terms of the deal weren't disclosed. MIT research scientist Alex Matveev and professor Nir Shavit founded Somerville, Massachusetts-based Neural Magic in 2018, inspired by their work in high-performance execution engines for AI. Neural Magic's software aims to process AI workloads on processors and GPUs at speeds equivalent to specialized AI chips (e.g. TPUs). By running models on off-the-shelf processors, which usually have more available memory, the company's software can realize these performance gains. Big tech companies like AMD and a host of other startups, including NeuReality, Deci, CoCoPie, OctoML and DeepCube, offer some sort of AI optimization software. But Neural Magic is one of the few with a free platform and a collection of open source tools to complement it. Neural Magic had so far managed to raise $50 million in venture capital from backers like Andreessen Horowitz, New Enterprise Associations, Amdocs, Comcast Ventures, Pillar VC and Ridgeline Ventures.
