Windows Subsystem for Linux

When Microsoft announced they were adding Bash support to Windows, they picked the right place to do it. It was announced at their Build developer conference last year, and it got a lot of applause. It was arguably one of the biggest additions to the Anniversary Update, and it wasn’t just the Bash shell either. Bash runs on Ubuntu which is running as a subsystem of Windows, allowing many Linux commands to work out of the box with no virtual machine necessary.

In the time since this was released last summer, Microsoft has been hard at work adding more features here. One of the biggest changes is they have moved from Ubuntu 14.04 to Ubuntu 16.04. It must be noted that it is not automatically updated, but will have the new version for new installs. You can try to upgrade it in-place, but the recommended method is to remove the WSL and re-add it.

They have also added more support for developer tools (source):

  • Core tools: apt, sed, grep, awk, top, tmux, ssh, scp, etc.
  • Shells: Bash, zsh, fish, etc.
  • Dev tools: vim, emacs, nano, git, gdb, etc.
  • Languages & platforms: Node.js & npm, Ruby & Gems, Java & Maven, Python & Pip, C/C++, C# & .NET Core & Nuget, Go, Rust, Haskell, Elixir/Erlang, etc.
  • Systems & Services: sshd, Apache, lighttpd, nginx, MySQL, PostgreSQL
  • And many others

INOTIFY

They have also added support for mapped network drives, mounting Windows drives, and quite a bit more. There is now support for file change notification support, network connection enumeration, and more. The amount of new features in the Linux Subsystem is fairly impressive, and Microsoft’s other departments could learn from these devs, who keep a detailed change log of everything they have added, and you can find it here:

    Well, so far all that's happened for me is that Minecraft has gone from about 25 fps to 5 or 6, with "game mode" turned off.

    For some of us, The update fails to install, even when using an ISO. To date, Microsoft tech support is stumped. The install gets to 75%, reboots...then fails.

    The new Windows Defender UI overhaul now nags at me that I've got a driver issue. Following the prompts it turns out that it doesn't like disabled devices. Well, that's how the Cisco VPN system works, the VPN adapter is disabled while not connected. Stop nagging me already!

    UWP is still needed for Windows tablets for instant resume and long battery life. There are a bunch of small tablets that run full Windows for less than $200 but they all use old Cherry Trail Z38xx chips, as no Apollo Lake parts go below 4W TDP.

    Anyway, I'm totally stoked about Windows Subsystem for Linux. It's been a pain running Ubuntu VMs on an Atom-based tablet because of VM integration issues and a big hit on battery life. Hopefully I can do dev work on a Windows tablet without the horror of Cygwin...

    And then I found out 32-bit Windows doesn't get WSL. Why, Microsoft, why? Ubuntu has 32-bit images of the latest releases.

    So it's back to Cygwin and VMs for me. Looks like a whole bunch of Atom machines are due to get EOL'd because they're stuck with 32-bit UEFI even though they have 64-bit CPUs, all because Microsoft couldn't get Connected Standby working properly on 64 bit Windows way back when.

    What is a 32bit Windows?

    "Consumers want more features, and sooner,"

    Are you sure about that? There are an awful lot of consumers who are going out of their way to avoid any of the new features in Creator's... and Anniversary... and Threshold 2... and RTM... and Windows 8.1... and Windows 8. MS had to force the new "features" on these consumers using every dirty trick they could think of even though Windows 10 was a free upgrade!

    I don't want new features. I want the old ones back! Things like user control over updates and telemetry, a desktop-centric UI featuring a complete lack of "app" garbage, no nags when I install or use non-MS software, no ads, no changing my settings, no uninstalling my stuff, changing my drivers, or downloading stuff I never asked for... those are all must-haves. Any product lacking any one of these isn't even worthy of consideration.

    Very true. Thank you very much for that comment.

    The bug as feature philosophy is gaining new ground in Microsoft strategy. And this is one of the richest companies in the world with practically unlimited resources. The future is bleak. I can already picture robots that shit their pants as a natural feature.

    A bunch of unneeded stuff and no fixes for older laptops - mostly driver
    And then it looks like new laptops have probs too. I am talking from personal experience.

    Jesus, when will they learn that one friggin place for settings is a lot better than two? Just go back to the old control panel for F's sake
