  • Where did you find that azure runs on linux?

    I dont know of anywhere that Microsoft confirms, officially, that Azure, itself, is largely running on Linux. They share stats about what workloads others are running on it, but not, to my knowledge, about what it is composed of.

    I suppose that would be an oversimplification, anyway.

    But that Azure itself is running mostly on Linux is an open secret among folks who spend time chatting with engineers who have worked on the framework of the Azure cloud.

    When I have chatted with them, Azure cloud engineers have displayed huge amouts of Linux experience while they sometimes needed to “phone a friend” to answer Windows server edition questions.

    For a variety of reasons related to how much longer people have been scaling Linux clusters, than Windows servers, this isn’t particularly shocking.



  • But, surely Windows is the wrong OS?

    Oh yes! To be clear - trying to put any version of Windows on a super-computer is every bit as insane as you might imagine. By what I heard in the rumor mill, it went every bit as badly as anyone might have guessed.

    But I like to root for an underdog, and it was neat to hear about Microsoft engineers trying to take the Windows kernel somewhere it had no rational excuse to run, perhaps by sheer force of will and hard work.


  • They are not all the same.

    Measure the diameter of the hole at the bottom of the water holding tank. It’s the main difference between older and newer toilets in the US.

    Any US toilet repair kit should list what diameter(s) it supports.

    Depth of the holding tank will vary as well, but most repair kits account for this. Some kits may require using a hand saw to cut some plastic tubes to fit smaller tanks. Other kits have an extendable or collapsible tube.



  • I wonder if the numbers are still this good if you consider more supercomputers.

    Great question. My guess is not terribly different.

    “Top 500 Supercomputers” is arguably a self-referential term. I’ve seen the term “super-computer” defined whether it was among the 500 fastest computer in the world, on the day it went live.

    As new super-computers come online, workloads from older ones tend to migrate to the new ones.

    So there usually aren’t a huge number of currently operating supercomputers outside of the top 500.

    When a super-computer falls toward the bottom of the top 500, there’s a good chance it is getting turned off soon.

    That said, I’m referring here only to the super-computers that spend a lot of time advertising their existence.

    I suspect there’s a decent number out there today that prefer not to be listed. But I have no reason to think those don’t also run Linux.


  • but it did not stick.

    Yeah. It was bad. The job of a Supercomputer is to be really fast and really parallel. Windows for Supercomputing was… not.

    I honestly thought it might make it, considering the engineering talent that Microsoft had.

    But I think time proves that Unix and Linux just had an insurmountable head start. Windows, to the best of my knowledge, never came close to closing the gap.




  • I’ve bluffed my way into technology changes every five or so years, across my career.

    It went, for me, like:

    Why do you want to do this, when you mostly have experience with that?

    “It looks interesting.”

    Do you have experience with this?

    “No. But I know how to read the documentation, I pay attention and ask questions when my colleagues explain something, and I studied the basics of this, in college.”


    It doesn’t usually land me the job. But all I needed was an occasional “yes” here or there, to get started on something new, and expand my experience.

    Plus, even the “no” interviews have still been good for my professional network.


  • Where would I even start.

    There’s a lot of good information provided video game reviewers. I tend to start there, when looking for something new.

    In particular, I’ve learned about entire genres such as “cozy games” and “couch co-op”, that way. Then, once I know what the genre I’m in the mood for is called I can search for “best cozy games of 2020”, to find ideas of what I might like to try.

    In order to not worry about whether each game will run, I feel that the SteamDeck is the current nicest all around game console available, followed by the Nintendo Switch.




  • The first thing I do to, if I need to get the size down, is swap out Gnome for one of the X11 Windows managers, usually XFCE.

    I usually do this by starting from the minimal install and building up, as schizo already suggested.

    That said, I guess I would be remiss if I didn’t point out that Linux Mint is an easy way to get Debian’s core with the XFCE window manager.

    Looks like Mint starts at 3GB - 8GB, depending on options chosen?

    Disclaimer: It’s honestly been awhile since I really paid attention to my own Linux install size, as long as it’s below 40GB.
