Nobody tell Steve Ballmer

Someone might need to check on Steve Ballmer. Microsoft has developed its own Linux distro, CBL-Mariner, and released it under the open source MIT License.

Microsoft said in the CBL-Mariner repository on GitHub that it's "an internal Linux distribution for Microsoft’s cloud infrastructure and edge products and services" that was "designed to provide a consistent platform for these devices and services" and "enhance Microsoft’s ability to stay current on Linux updates" moving forward.

    It isn't the future until MS comes out with Linux for it end user......dual boot with Windows or Linux.

    betcha some subtle simple zero day backdoors are in it with the intent for the open source community to clone and copy this MIT License software.....it's the end of Linux given enough marketing hype ($$$$) for this distro. Why else would MS take efforts when Linux is fine w/o MS?

    Microsoft pretty clearly wants to be operating a for-subscription service. It doesn't make sense for an OS to be a for-subscription service. So what would make sense would be adopting a Linux kernel, then offering a 'Windows Experience' on a subscription basis. Or they could go the Apple route and just heavily customize and develop on top of the kernel. For now, though, this makes sense as the cloud is dominated by Linux and not even Microsoft is going to pretend that Windows has a chance there. Also, we should never forget that no one should have ever listened to Steve Ballmer about anything, ever. HE is the cancer. He almost killed Microsoft completely with his ludicrous competition-focused approach to the workplace. He posted leaderboards on every wall where members of the same teams would compete against each other to score points, with the leaderboards updating in realtime. Teams within Microsoft them competed against each other on points as well. It created the most hostile, inhumane, toxic environment imaginable. No one would ever help a coworker because that meant they would be scoring points while you were losing out. You were heavily penalized through the very nature of the system for doing anything remotely cooperative or helpful to the company as a whole. It was disgusting, and should be held up as a prime example of what to never, ever, ever do.

    Released under the MIT license.
    The MIT license is not quite compatible with the GPL license which Linux is released under.
    You can relicense MIT licensed software under a GPL license, but you cannot relicense GPL licensed software with the MIT license.

    Nobody should be suprised. MS is now a cloud company with much, if not most, of its revenue coming from Azure. Last I checked Linux usage on Azure was about even with Windows.

    Welcome to the new Microx OS, the full Windows experience in Linux, it comes with a fixed horrible desktop environment you cannot change no matter what, uses 16 gigs of Ram to run just a plain-looking OS, more simple than XFC4 in version 2, comes with telemetry, geolocation, spies on you and keep uploading copies of your data to Microsoft, track all your online activities and web browsing, choking your internet connection, keeps always using 100 % disk for swap, regardless of you RAM size which no app can use to the full extent, so it will burn your SSD in a year or less, it becomes slower and slower as times goes on, takes forever to boot, crashes from time to time, showing a lovely blue screen, have forced updates that took forever and don't let you work, all open software you use like Blender, Krita, etc, takes forever to start up, have rare glitches and run slower. Drivers for hardware are a joke, backdoors, viruses, malware are a must, we will sell you the vax to the viruses we create (solid business model).
    and working in a local network is hell.
    Also, you have to register with us to use the software and pay a monthly subscription to use it.

    Enjoy!

  • Nothing new. When PCs were first invented, they made a version of UNIX.

    But I guess none of you would remember this

    Of coarse - this will ensure that the end users don't need to spend time to adapt to a whole new concept 😎
