Vs code remote with WSL is a game changer

[@nmihaylove]

That's why in Unix under the X WIndows system you can run any app on one machine and have it show up on another. Also, can this remote to an arbitrary Linux installation, say on another machine, or they gimped it to only work with local WSL?

@@k1ngjulien_ I've gotten it to work, graphical glitches abound, performance is dogshit. Code is a hardware accelerated electron app, not some graphical emacs using motif. VS Code remoting is the editor running locally but operating on remote files. The neat bit is that extensions that depend on remotely installed components like go's gofmt or delve run just the same as they do locally.

It's honestly not a bad advertisement for Linux. But prior to WSL, nothing stopped someone curious about Linux running it under Windows in a virtual machine. So ultimately Microsoft isn't losing much here and probably have more to gain from it.

[@queenannsrevenge100]

They keep calling them virtual machines - they sound more like containers! Fascinating!

A container is a type of virtual machine, so it makes sense that they are similar.

[@hanspetervollhorst1]

Expected to see a Windows Subsystem for Linux, not a Linux Subsystem for Windows. Chapeau nonetheless

[@ivailogeimara]

I think it's called Windows Subsystem for Linux because it's a subsystem in Windows that translates Linux (kernel) calls to Windows (kernel). WSL is kinda short for "Windows' subsystem for translating Linux kernel calls to Windows kernel calls" or "Windows subsystem for Linux kernel calls" or "Subsystem within Windows for Linux calls". Now WSL2 running Linux kernel I think makes the name wrong (unless it still translates Linux kernel calls to Windows kernel call despite actually running Linux kernel) but it's known name so it'll be stupid to change it.

@@tmbrwn osx is terrible. It looks like a Unix, but everthing is a bit different and missing parts. Also, Linux has its own flavor of posix. And OSX has its own libraries that you really should use instead of unix/posix layer. Basically it just creates illusion of being a Unix. There's this reason why cygwin fails, wine fails, interix fails and then WSL1 failed. It's never quit like the original. So virtualizing the real thing is the best option. You pay a bit of performance, but hardware is cheap.

[@vinoth9381]

Is it possible to access a linux filesystem in a physical partition or a 2nd harddisk from WSL2.

[@shamringo7438]

It might be possible since FUSE will work on WSL 2 + Run as admin. macOS users are using FUSE to mount ext4 drives. The same can happen to WSL 2 if somebody makes one that is. Or alternatively, WSL 2 already uses ext4 as their root filesystem. If you run WSL as admin, you might be able to just mount the drive directly. For now all we can do it wait.

Pouya Samie I have used Linux for the past three years, while I’m not an expert, I know at least a thing or two to set up and and get my Arch i3 up and running. The problem with Linux is the hardware compatibility. While for you the experience was good, mine was terrible. My system would freeze occasionally, wifi would not work all the time and I lose all the features like fingerprint scanner and such. Then comes HiDPI scaling, it’s an absolute nightmare on some laptops and you end up with something which only does the work but doesn’t feel right. Scrolling a webpage is significantly slower as the lines per scroll is lower than Windows. Gaming is a thing where I just don’t want to spend any more of my precious time and interest so I just ended up with Windows. It just works!

[@WispyFrost371]

USB comes under sharing hardware as asked in that QnA about sharing GPUs, so once that's enabled there'll be a more direct link. Otherwise by forwarding the Windows mount point to WSL, you might be able to do it on WSL 1 as well

I mean, let's be honest, no amount of benefits will change someone's choice environment they had for year, for example as a Linux user for 5 years I have no reason to use Windows as all the day to day things I need are here and no shiny new thing there will change it But what do I know tbh, just find it quite stupid of many people acting like "or you commit 100% to Linux or you don't" as it just makes people go away

[@northshorepx]

I know - dumb people gonna dumb! MS knows the desktop is not the future but getting people to their cloud is. They want to make it easy for any dev and thus any app to be developed so you're likely to consider using Azure. I've been a MS technologies dev since 1988 and I can tell you that WSL is the most cool thing I've played with in years!!! You should watch the new terminal talk - I think you're going to like it!

[@skewty]

As a current Linux user who will likely switch back to Windows, I disagree. The X/Wayland issue is going nowhere fast (still no great remote desktop in Wayland + poor video driver support), and Gnome development moves forward at drunken snail pace. Remove 6 working features, fix 3 and and add 1 nobody wants while ignoring most day-to-day essential features and bugs like icon view in the file chooser. Now we have the SNAP / Flatpak / AppImage battle on top of the DEB / RPM battle.. The fat cats in the Linux Foundation have little to no interest in investing in the Desktop (interest is shown by spending money, not words). Until Canonical and IBM can get together on a distribution method, I just see the ongoing mess we have seen for the last decade continuing.

[@northshorepx]

From what they are saying at the moment (I tried this yesterday) wsl 1 works across the board w10 home upwards. On WSL1 you need docker for windows to run linux containers and these run in a hyperV VM (MobyLinux). Since hyper V VMs are not available on W10 home and docker. However WSL2 uses a linux kernel running directly in the base hyper visor and it's a new full kernel and will be available on W10 home. This full kernel will also mean that the docker for linux will run on this kernel in WSL2. This means, if I understand correctly, that docker for linux will run on W10 home (though other hyper V featurers like other VMs may not), and thus you should be able to run Linux containers on W10 home. I hope that helps.
