You can update to Windows Subsystem for Linux GUI while still using Windows 10, as described at https://github.com/microsoft/wslg . Emacs and gnuplot work fine, and that's all I need.

rbanffy2• 5 years ago

You can also get this great feature in standalone version, for free, and without any Linux compatibility or Windows integration issues. Definitively recommend checking at ubuntu.com for it ;-)

How do I use that to run windows games?

pram• 5 years ago

Link should have been to Arch Linux. 3/10

Otter-man• 5 years ago

Sadly, is seems you can't get on Dev or Beta channel since June 24th (if you weren't enrolled before), so you won't be able to get the Insider build with WSLg on your existing win10. Only if you install it from clean ISO and update. Source: https://answers.microsoft.com/en-us/insider/forum/all/how-in...

I tried it now and you could only choose Release Preview channel which still has only build 19044.

p1necone3• 5 years ago

Yep - seems like they originally did all the work to have it running in win 10, and then decided to take it away as a carrot to get people to upgrade to win 11.

I'm probably going to make 10 the last version of Windows I install.

smusamashah2• 5 years ago

The article says Windows 10 but on insider preview you only get option to upgrade to Windows 11. Updating Windows 10 alone isn't an option anymore. See https://superuser.com/questions/1676383/how-to-skip-update-t...

2022 is The Year of Linux on Windows Desktop ;-)

Also, you shouldn't change the original title, which is probably correct.

Nevertheless you can edit it back.

Hamuko2• 5 years ago

Does it finally automatically mount my network shares?

ahupp• 5 years ago

It now supports mounting from fstab on startup.

Hamuko2• 5 years ago

That was supposedly supported in Windows 10 I believe. I think I got the command to work once but only once.

judge20207• 5 years ago

The whole setup with WSLg is pretty nice. Virt-manager works, but more importantly with nested AMD virtualization (which I believe is indeed limited to Windows 11; Windows 10 has nested Intel support, though) it was super easy to use macOS-Simple-KVM[0] to run a Mac VM, even if the FS performance isn't great and I don't have an extra AMD card lying around to passthrough for hardware acceleration.

smusamashah2• 5 years ago

WSLg requires Windows 11. I installed it only to try WSLg. The UI didn't scale with Windows scaling/DPI settings which was very annoying. Setting the display resolution reduced sharpness of all font. Not being a Linux user primarily and hating Windows 11 annoyances, regretted the upgrade and reverted back to Win 10.

jgilias• 5 years ago

One can wish. The more likely end game seems to be one where no one actually bothers using a real Linux installation, as you can do everything you'd need Linux for on your Windows machine. But your Windows machine has become a 'trusted computing' device that only boots and runs most software if it 'hasn't been tampered with'. Say, by actually installing Linux on it.

Edit:

Hope not! But actually kind of agree with you here.

brundolf• 5 years ago

Right, they've ceded the server space to Linux but want to cement Windows' position on desktops in a Linux-server world (maybe regaining some ground from Macs in the process, since this is one of the reasons they're so popular with devs)

peakaboo• 5 years ago

I guess there are few of us, but I would absolutely never use that subsystem rather than a real Linux system.

judge20207• 5 years ago

Did we mention that a TPM isn’t going to protect you from UEFI malware that was planted on the device by a rogue agent at manufacture time?

I find this to be a pretty weak strawman, and one that not many people would consider to be part of their threat model (and if they are, they'd just purchase the part from a brick-and-mortar store so that, if there is malware, it's non-targeted).

Microsoft is mostly doing this for their endpoint security enterprise customers. The objectives aren't exactly hidden, either:

- Don't want anyone to be able to get data off of a bitlocker-encrypted drive[0]

- Don't allow things like O365 login credentials (including temporary auth tokens) to be pulled off a drive[1]

- Prevent thunderbolt 3 DMA (eg. from a rogue usb on the back of the computer)[2]

And yes, they probably also don't want people to keep hacking online video games, which is why Riot uses TPM attestation as an additional security measure to preventing people banned for hacking from evading bans in Valorant[3].

I am pretty sure that WSL was implemented to avoid the gradual loss of users, most of them being developers, to Linux. There is very little reason for existing Linux users to adopt Windows due to WSL.

gerdesj2• 5 years ago

But I don't want to run Windows and haven't done so for roughly 20 years.

My Dell made Arch lappie runs up attested via a TPM 2.0. I boot UEFI, Secure boot to kernel and initrd.

mr_toad2• 5 years ago

you can do everything you'd need Linux for on your Windows machine

On a Windows machine I’d prefer to use Azure cloud shell than WSL.

squarefoot• 5 years ago

The more likely end game seems to be one where no one actually bothers using a real Linux installation, as you can do everything you'd need Linux for on your Windows machine.

I'm 100% convinced this is Microsoft's actual goal, and it's going to succeed very quickly at least on the desktop. Then one day, when a good number of apps will conveniently require WSL to run properly, or to run at all, MS could build their own Linux distribution containing licensed parts of Windows (drivers for closed hardware, graphics libraries, etc.) de facto displacing the original Linux from every other field of application including embedded, automotive, industrial, etc.

Buttons840• 5 years ago

That may be their strategy, but "Full Linux compatibility plus Windows Updates!" doesn't appeal to me, so I'll stick with pure Linux.

smitty1e• 5 years ago

Yep. Windows will be to its Linux kernel as Aqua to Darwin.

Been predicting it for years.

fortran773• 5 years ago

Impossible. Windows is a modern microkernel architecture. Linux is an Apollo-era monolith.

Noughmad• 5 years ago

Far more in line with their EEE tradition:

- 2024: Custom proprietary extensions in WSL, hidden "incentives" to make sure some important software runs only on WSL

- 2027: Nobody uses Linux without WSL anymore

- 2030: WSL now costs $200 per year.

gopiandcode• 5 years ago

Don't forget, before the last step, they'll first subsidise universities and schools to explicitly train their students to have a dependence on WSL, so that they can maximally exploit their users when they introduce a fee.

cwyers• 5 years ago

Except Microsoft doesn't offer WSL-based hosting, and they currently don't offer their own Linux distro. This is a complement to their Azure business, basically.

bitwize• 5 years ago

Yeah, I read that erotic fanfic back when ESR wrote it: http://esr.ibiblio.org/?p=8764

It's not going to happen. The Windows NT kernel is one of Microsoft's greatest assets; in fact it's better designed than Linux on many axes. Until recently it had better support for async I/O (and the developer experience of io_uring may still not measure up to IOCP under Windows), it was designed for multithreading, and it has a more advanced security model. It also has a more advanced driver model, which is to say it has a driver model at all. The fact that there's a standard ABI for drivers means hardware Just Works under Windows and is still incredibly fiddly under Linux. Microsoft essentially has stewardship over the entire PC platform because they play very nicely with OEMs and make hardware easy for Windows to support.

They are not going to give that up. It'd be the OS-kernel equivalent of giving up Alpha for Itanium.

If anything, the future of Linux is to be a guest under Windows NT. How many Hackernews have I heard repeat the mantra that the best Linux desktop environment is WSL?

mr_toad2• 5 years ago

The future of Linux is the cloud, and servers, and routers and IOT devices and well, everything except corporate desktops.

That would only happen if sometime between 2027 and 2030 they buy out both Linus and the Linux Foundation, re-write all GPL code not owned by the Foundation, and re license Linux to some other license other than GPL.

DeathArrow13• 5 years ago

I think it would be much easier to just design another POSIX compatible OS and give users some incentive over Linux: stable ABI, stable API, software and hardware that just works out of the box and don't need configuration and maintenance.

To get chrome / vscode / edge to resize correctly I needed to add some options to turn off the gpu acceleration (I think judging by edge://gpu).

--enable-features=UseOzonePlatform --ozone-platform=wayland

There are issues raised on github (issue #272/273) so I'm guessing it's mostly driver related. Other than that it seems fairly seemless, the apps appear in an ubuntu folder on the windows start menu.

hwestiii• 5 years ago

Does anyone use it seriously? I guess I need better informational resources. I’m still wondering where the man pages are.

veesahni2• 5 years ago

A number of years ago WSL completely replaced virtualbox and cygwin for me.

WSL2 + VSCode w/ WSL plugin provide a fluid and fast experience if the code sits inside linux.

dboreham3• 5 years ago

Google "install WSL2". Man pages come with Linux so they're where they always were.

iakov2• 5 years ago

I use WSL daily on my desktop and laptop for work - full stack development and sysadmin/devops. Familiar CLI tools available right from my Windows desktop are a great thing.

I’m really, really happy with WSL since I can use one powerful PC for work, music recording and occasional gaming.

fartcannon3• 5 years ago

Yeah, just like Linux but with added spyware!

smackeyacky• 5 years ago

Anyone using docker desktop on Windows has been using WSL. WSL2. I use debian as my WSL2 distribution, it's OK as a development environment enhancer in that it removes the need to learn Powershell to do anything productive with a CLI.

It's not as good as running Debian directly. WSL2 was the motivation I used to switch to debian full time on my main development machine, so I'm not sure Microsoft can safely assume that having WSL2 means people won't dual boot or simply move on.

neves• 5 years ago

Yes. Best dev env that I used. Linux tools and Windows Gui. Problem os that eats too much memory.

__jem• 5 years ago

Yes, I find it a far superior dev setup than a standard corporate Mac. Everything about Windows is inferior to macOS, but I spend 90% of my time in a shell, and having my familiar Arch setup and tools vs crumbling macOS Unix is well worth the trade-off of minor annoyances like terrible start menu and file explorer. Windows Terminal is actually pretty okay.

tehbeard3• 5 years ago

WSL for me:

- Great scripting environment for a number of "used weekly/monthly" tools (stuff to test backups, automate some processes) Maybe this is more an indication of my lack of PowerShell knowledge to do the same.

- Good way for me to test most Linux binaries our scripts / code might use (wkhtml2pdf seemed to experience this, might have been because any windows bins we found were out of date/mislabelled.)

- Ansible "Controller/Host" , My god, my favourite usecase for WSL. It just works. Still have to deal with Ansibles bytespam errors, but you don't need a whole VM to just to update some servers.

NelsonMinar4• 5 years ago

I use WSL all the time, have for years. It's excellent. I much prefer it to my last setup which was trying to MacOS act like a modern Unix.

Not sure what you mean by "man pages". The full Linux man system is there, of course. WSL itself has very few commands of its own. There's wsl.exe but you almost never use it. It has no man page per se but it does have a good --help string as well as online docs: https://docs.microsoft.com/en-us/windows/wsl/basic-commands

cloudking• 5 years ago

Yes it's great, I can spin up WSL to get a full Linux environment for web development, mimicking my production environments. I can use Windows IDEs to edit and browsers to test. Even tools like Browsersync work seamlessly running on Linux and syncing on Windows browsers. When I'm finished work, I can shut down the dev environment and play my favorite Windows games without having to dual boot :)

fortran773• 5 years ago

I'm building two things, in two separate WSL environments, for two different clients, right now on my Windows 11 Microsoft Surface Studio Laptop, as I'm looking at Hacker News. It works great.

awslattery• 5 years ago

I've used it without issues for years. I also used Crostini containerized environments on my Pixelbook until I just couldn't stand the terribly inefficient 7th gen Intel processor on it.

At work, we support more than half the team on it. Company gave a stipend to build or BYOD, and a lot of folks opted for Win10 w/ WSL for gaming purposes (afaik, Wine didn't support anti-cheat in several titles until recently?)

For me, being able to confidently use any non-Apple device, have full driver support for touchscreen/wifi/speakers/etc. and maintain containerized development environments, is extremely attractive.

kyriakos5• 5 years ago

I use it professionally since wsl1. Wsl2 and docker play nice together, it just works. Pretty good for Web development.

fleaaaa2• 5 years ago

Been using since yhe beginning of wsl without major problems, while working on music production without dualbooting. I probably haven't boot up linux for about a year.. this strategy apparently works for many.

GordonS3• 5 years ago

Yes, me. Windows is by far my preferred desktop OS, but on the command line I greatly prefer Linux, bash etc.

So I use graphical stuff in Windows (JetBrains Rider, VSCode, MS Office, Firefox etc), with all my dev files in WSL2. Works great, the vest of both worlds!

Previously I was using Git Bash on Windows, which actually worked pretty well too (apart from occasional file system path issues), but WSL2 takes it to another level.

rvz• 5 years ago

So this article is telling me that the best Linux distribution for the desktop is Windows?

Makes sense.

dboreham3• 5 years ago

For desktop/laptop use, yes.

oscribinn• 5 years ago

If you don't mind being coupled to an arcane filesystem, networking shitting the bed when you connect to VPN, settings you can't change, software you don't want but shouldn't remove, functionality that is simple to configure in KDE split across god knows how many UI/UX schemes and usually requiring third party applications, worse performance than native, and best of all having your open computing environment running virtualized on top of a closed system requiring you to migrate product keys/activation/whatever for a simple reinstall - yeah, WSL is the best Linux distro for you, bud.

samsaga2• 5 years ago

What's the performance? WSL2 was really slow for hard disk access.

judge20207• 5 years ago

WSL2 on Windows 11 uses the same file translation layer between the host FS and the VM FS as it did on 10, so pretty slow. The big improvement with WSLg is that now you can run desktop linux apps (such as your IDE) within the WSL file world, which should give you near-native FS performance as long as you're not accessing /mnt (and if you want to browse those files on Windows, you can always open \\wsl$ in file explorer).

dboreham3• 5 years ago

It's not slow for native Linux filesystem, only if you access the host NTFS. Avoid doing that. Git clone inside WSL2.

veesahni2• 5 years ago

Both WSL1 and WSL2 are slow for cross-platform disk access... but WSL2 is fast for within-the-vm disk access (unlike WSL1).

Means if code resides in the linux vm and you can somehow edit it directly (eg: VSCode + WSL2 plugin), it's fast.

kyriakos5• 5 years ago

Here are some benchmarks

https://www.phoronix.com/scan.php?page=article&item=windows1...

They don't account for disk performance when accessing Windows storage though. If you stick to wsl2 storage paths performance is great.

jayflux4• 5 years ago

It’s only slow if you’re git cloning/doing stuff inside of /mnt. You need to use the WSL file system

encryptluks2• 5 years ago

They will keep trying and failing. The only reason people still use Windows is the exclusive software and games. Once someone gets proper virtual GPU working for most GPUs then I assure you the preferred choice will be the other way around.

libertine• 5 years ago

The only reason people still use Windows is the exclusive software and games.

But that's quite a lot of stuff to be considered "the only reason".

fleaaaa2• 5 years ago

'Exclusive apps' means entire ecosystem outside of dev tool, this is the reason why people says dev should communicate more outside of their ring.

29athrowaway2• 5 years ago

What WSL really means is Linux Subsystem for Windows

midasuni• 5 years ago

It is a subsystem of windows used for doing linux things.

I don’t get the appeal personally, but some people like Microsoft I guess.

29athrowaway2• 5 years ago

It is a creative and confusing use of grammar.

filereaper• 5 years ago

I had to get a coworker set up under WSL because of a goofup with IT and instead of shipping a Mac this coworker ended up with a Windows machine and all of our tooling was Unix based.

I had had them setup with WSL as a way of moving forward, here's a few things I noticed:

- different home directories, the different distros are accessed as network shares. It can get confusing where "Home" is unless you explicitly stumble a few times and verify always where files are.

- Issues with CR/LF. You need to be careful using native windows tooling and having saved files in Windows line endings vs Unix. For non-savvy users the content looks correct but on Unix the tooling will fail in weird ways.

- Visual Studio Code integration was actually excellent, my coworker ended up using VS Code to do Filesystem operations more so than using Windows Explorer.

- The new Windows Terminal is fantastic, hopefully its bundled with Win 11.

I'm really grateful for the technical capabilities that WSL brings out. I hope the dev teams are focused on fixing the subtle UX issues that trip up users.

fartcannon3• 5 years ago

You needed a unix, so you tried WSL? You would have been much better served by Linux.

tehbeard3• 5 years ago

a goofup with IT and instead of shipping a Mac this coworker ended up with a Windows machine

That kinda implies this isn't a small shop, so "breaking" a windows machine IT provisioned to put Linux onto it might be out of the question, both in terms of requisition, access to the UEFI, or even network configuration.

Or said coworker is more familiar with Mac/Windows than <Insert Linux Distro and particular window manager here>, so this is best of a bad situation.

phendrenad25• 5 years ago

Sadly, corporate IT usually mandates Mac/Windows, so nuking it and installing Linux is probably a no-go.

Also BOM marks, which Powershell loves to output. Took a while for me to figure out what was putting 2 extra bytes into files.

Edit: 3 bytes, not 2 (thanks!)

ploxiln• 5 years ago

The useless utf-8 BOM is 3 bytes ... were you also getting utf-16 encoded text?

ChrisSD• 5 years ago

Powershell has stopped doing that in that newer version. I think since 6 or 7. On Windows 10 you do have to install it separately though.

zz8652• 5 years ago

Issues with CR/LF.

Is this still really a thing? even notepad can handle LF. I guess the default could still be crlf for some apps.

Mogzol3• 5 years ago

I think one of the main problems is that when you install git for windows, the default setting is to convert LF to CRLF when checking out code. This can cause a bunch of issues if you later try to work with those files within WSL (especially when doing any git-related stuff). I don't really understand why that's the default, or even why it's presented as an option during installation, it's been ages since I actually had issues reading/editing Unix-style files in Windows.

int_19h3• 5 years ago

It's usually the other way around these days - most Windows apps can handle LF just fine, but Unix apps often cannot handle CR LF. So if you use Windows to generate a text file, things break when you try to use it from WSL.

Notanothertoo• 5 years ago

I would not work until you got me a Mac. This poor soul.

smileybarry• 5 years ago

- The new Windows Terminal is fantastic, hopefully its bundled with Win 11.

It is, and it's even the default prompt in the Win+X menu

bradford2• 5 years ago

I was a bit disappointed when I tried using a package in WSL and found that CUDA wasn't supported.

It wasn't entirely clear from from the article, but I hope these updates fix that.

NelsonMinar4• 5 years ago

CUDA is supported, with some limitations. https://docs.nvidia.com/cuda/wsl-user-guide/index.html

bradford2• 5 years ago

thanks! last time I checked it required installation of beta drivers which wasn't something I was very excited about doing.

Kon5ole• 5 years ago

I just found out you can actually run slackware under wsl:

https://github.com/Mohsens22/WSLackware

Brian_K_White5• 5 years ago

Can't access usb hardware.

I do a lot of things that use usb rs232 adapters or things that look like them, and I support both linux and mac effortlessly (and even freebsd and any other unix) and none of it is possible under wsl2.

If all you want to do is write web services, there are native windows versions of all the scripting languages and web frameworks.

If you have some reason to actually use linux, then just use it. It's free and well-documented. Nothing's stopping you.

If MS actually cared about supporting developers, then they would provide a 1st class form of Wine, so that windows apps could be run from within linux.

Since they don't do that, this exposes that they don't actually care what would be convenient for you, and so, you should decline to work with people who don't work with you. That's how you can see through bullshit.

You should reject their products and sales pitches until their behaviour actually changes, and disregard all the lip service, "gifts" with strings, and excuses for dark patterns. Use their stuff when you must, but under duress and seeking other options at every turn.

watermelon02• 5 years ago

Regarding the USB hardware access, you can use USB-over-network solutions, to share devices with WSL2 VM.

I've had good experience with https://www.virtualhere.com/usb_client_software.

Brian_K_White5• 5 years ago

Attaching a small computer running some other code besides wsl2, is not an answer to the charge that wsl2 can't access usb. It still isn't accessing usb. The code on the usb server device is.

That's not semantics. What I mea is:

For any low level code of my own that I wrote to run on *ix, I can just as easily run that same code on an arduino or pi, and wsl2 and the usb server hardware would just be pointless extras.

For any code that I didn't write and can't port (say, closed source xilinx fpga programmer) there are native windows versions which work better and are better supported than the linux version anway. So here too wsl and usb server harware would both be pointless extras and backwards.

People are bamboozled and forgetting to step back and remember what the point of doing something even was in the first place.

I say it's a mistake to even get sucked in to the question of how to work around any deficiency in wsl, instead of asking why you even care or want to run a linux app on windows in the first place.

gavinray• 5 years ago

I feel like this is somewhat -- err, not a lie, but not quite the truth. There's a word for it but it's eluding me atm -- "misadvertised"?

The headline of the article is: "WSL is finally easy to install—and offers automatic sound/graphics support."

All of this stuff was available before Windows 11, to anyone/everyone.

I know, because the way I installed WSL2 on Windows 10 was the way mentioned in the article ("wsl --install"), and ditto for using the new/experimental Linux GUI stuff.

This was readily available for anyone who bothered to install an Insiders ISO, and there are tutorials and articles about this for Win10 specifically:

  https://www.omgubuntu.co.uk/how-to-install-wsl2-on-windows-10

anyone who bothered to install an Insiders ISO

That is a big no from me. I am not interested in being Microsofts unpaid alpha / beta tester, when I get in return in a less stable operating system and some unfinished bits.

I hate how Microsoft keeps running huge blog campaigns about this or that new features and once you dig into it "Just install the Insider ISO".

No. Tell me when you are done developing and it is ready for production.

zamadatix2• 5 years ago

They're release cycle is 6 months, I'm perfectly fine with them blogging about what's coming in half a year and available to try out early. Nothing to get worked up about.

gexla• 5 years ago

I had one problem after another with WSL. That made me question why I was even bothering when I could just use Hyper-v instead. I still don't get why you would use WSL. I guess MS is trying to make a more seamless experience for people who aren't Linux savvy but want some of the capabilities?

dgellow6• 5 years ago

Do you have the same counter to other dev/beta releases, such as firefox nightly, or is it only considered evil “unpaid work” when Microsoft do it?

1vuio0pswjnm7• 5 years ago

Didnt Microsoft tell the press there would be no more Windows versions after 10. The title is "Part of Windows 11 is a revamped WSL". This begs the question, What is (new in) the other part. It is almost as if this marketing is being employed as a distraction.

The disclosed changes to Windows 10 that comprise "Windows 11" sound non-critical, like Firefox changing its UI for the umpteenth time without ever disclosing underlying reasons: https://en.wikipedia.org/wiki/Features_new_to_Windows_11

beowulfey2• 5 years ago

Surely you don’t equate installing Insider Builds to having it built into the OS itself by default?

That’s like saying my crappy economy car can win races because I could install a new engine. Sure it’s available to me already but that doesn’t mean I always want to go through the effort to get there.

Check the guidelines, it encourages neutering headlines in multiple ways; believe the idea is people can form their own judgement on whether it's good or bad.

sp332• 5 years ago

HN automatically edits out some patterns from titles. If it happens to you and you want to put it back, you can just edit the title again after submission and it will stick.

p1necone3• 5 years ago

Because it's an opinion and doesn't give any useful information to anyone reading the thread/article.

skolos• 5 years ago

Without "the best" the title reads to me as that they somehow removed chunk of original Windows and replaced it with WSL. That's why I came to this topic. I thought to myself - really - so they now replacing windows code with Linux? Original title is clear and not clickbaity.

joe_the_user• 5 years ago

I found the headline here actually incomprehensible. Had Microsoft built Windows 11 on top of WSL? Built part of it that way?

What you'd means is "Windows 11 includes a revamped Windows Subsystem for Linux" if you wanted to removed the editorializing. But the article is editorializing - they don't like the rest of windows 11 and say so.

GordonS3• 5 years ago

But it's the opinion of the article author - the article that is being linked to. And removing this makes the title nonsensical.

Unless the title is too long or is obvious scummy clickbait, IMHO titles shouldn't be editorialised.

I tried installing wsl twice during the beta and both cases it failed to boot afterwards work a boot error about some threading stuff. Needing a full reinstall in both cases

Now that it's live I'm very reluctant to do this again and have to set everything up again if it fails. Though I suppose I can just pull an image off it...

That sounds like the hyper-v issue related to shared memory between the CPU and integrated graphics. Supposedly changing the value of the "UMA buffer size" in the BIOS works around the issue.

Well if you explain to me how can I use Linux desktop without configuring it a lot, how can I run Visual Studio, Photoshop, Lightroom, Adobe Xd and 3ds Max on it natively, I will give it the 101th chance.

On the desktop I care about applications more than I care about the operating system. The operating system should just not stay in my way, complicate things for me or consume my time.

ImaCake• 5 years ago

This is it for me to. I have tried so many times to jump to linux and it never works out. I mostly use macOS for unix stuff because it works without breaking all the time. Windows for gaming and some light terminal use in WSL.

JiNCMG• 5 years ago

If you gonna do dev on WSL then make sure all of it is on Linux. Don't mix and match.

They still haven't corrected the SEVERE disk read speed when accessing a Windows directory. For example, if you use zsh/Oh-My-Zsh and have any of the themes setup that pulls git info for the prompt (over 99% of them do this), cd into a git repo on your Windows side: cd /mnt/c/repos/example_git and expect a minimum of a 1 minute wait for simple repos.

The WSL IP Address changes on every restart.... ALWAYS. So trying to setup a local web server for testing becomes a hassle.

This should only be true if you're doing funny network stuff. On my machine, exposing WSL2 with 127.0.0.1:8080 allows me to connect on my Windows browser: https://i.judge.sh/shocked/Punch/WindowsTerminal_whYLqVLsIM....

kyriakos5• 5 years ago

That's wierd. Any server I run on wsl side can be accessed via localhost from Windows side. Been like this since the beginning of wsl if I'm not mistaken.

Mogzol3• 5 years ago

One issue that I've run into is that if you only bind to IPv6 in WSL, then you will only be able to access the service using IPv6 on the Windows side (i.e. ::1 works, but 127.0.0.1 doesn't). OSs usually automatically bind to IPv4 whenever you bind to IPv6, but that's not the case with WSL (actually, it does bind to both, but only inside WSL, not on the Windows end). Lots of programs (like node) bind to IPv6 by default, so this can catch people off guard and they wonder why 127.0.0.1 or localhost isn't working.

Here's the github issue about it: https://github.com/microsoft/WSL/issues/4851

jayflux4• 5 years ago

cd into a git repo on your Windows side: cd /mnt/c/repos/example_git and expect a minimum of a 1 minute wait for simple repos.

Yes that will be slow, don’t use /mnt, anything under that directly will crawl. Use /home or somewhere else and save your work there. In VSCode you can access any dir and now there’s gui support so there’s no excuse to be using /mnt now. I believe some docs on WSL do tell you this

The WSL IP Address changes on every restart.... ALWAYS. So trying to setup a local web server for testing becomes a hassle.

That’s weird, I’ve never had any issues relating to running a web server. Listening on a port in WSL automatically exposes it on Windows. I’ve not had to configure anything when restarting etc.

abdusco3• 5 years ago

I occasionally run into an issue that breaks localhost port forwarding. I can access the service that's running inside WSL2 via its actual IP (172.#.#.#) when 127.0.0.1 breaks. But that IP address changes every time WSL instance restarts.

I've had to set up a scheduled task[0] to update an entry in my hosts file every time WSL is assigned a new IP address, which works well enough.

I do all my dev on Windows side and I use WSL from time to time to quickly test builds.

`localhost` always resolves both machines without issue, it’s when you hard code 127.0.0.1 or ::1 instead of localhost, you end up with shenanigans.

unfortunately there's fundamental issues with file operations on NT:

* you can't delete an opened file, which means every folder delete/move operation has to enumerate all descendents to acquire exclusive locks.

* every file operation goes through a filter driver (think virus scanners)

* the kernel parses path names, and (I think) maybe dispatches one operation per path element.

all of the above can't be fixed due to compatibility apparently. that's why WSL2 moved off of NTFS.

darthrupert4• 5 years ago

My best choice was going back to Linux. Everything is simple and fast. It's difficult to say if this improves my efficiency, but I feel a lot better.

Do yourself a favor. Go for the real thing, don't accept poor substitutes.

* Lots of programs don't work properly (citation needed, can't remember specifics)

* You can only run command line programs, although I understand this could be different in Windows 11

My last job mandated windows laptops so I used WSL for a couple of months before I got too frustrated and just ran a virtualbox VM.

Any virtualization solution has the complexity of the sum of the environments being run simultaneously, the virtualization solution, and the surface where all 3 interact. Furthermore the guest solution inherently deals with the system at a higher level wherein you are stuck with how the host handles lower level aspects.

Such a system is simultaneously worse and more complicated as a necessary price for running both native windows applications and linux ones. In most cases you would be better off just running Windows or running actual Linux.

For example my Linux system has a ZFS root filesystem which provides a lot of interesting features including the ability to boot a prior version of my install at startup, along with 37 other useful things. Running a linux VM with that feature wouldn't magically port this functionality to the rest of the system.

My Linux system is vastly less likely to fall victim to a cryptolocker or other malware situation but running a vm under my Windows desktop wouldn't deliver this benefit.

My Linux system handles virtual desktops per monitor making it easy to swap one monitor at a time to a different workspace or all together if I please. Again neither running an app via a compatibility layer nor a fullscreen VM would provide this functionality.

WSL is Linux light without most of the interesting features and able to be withdrawn any given year by Microsoft. Worse it could be extended in ways that depend on windows features in a classic Microsoft move.

shanoaice2• 5 years ago

One of the most frustrating thing is that WSL is not a booted Linux. Systemd and other things don't work out of the box even in WSL2. In WSL1 it is almost impossible to make Systemd work, and in WSL2 a wrapper is needed to create a SUID 1 (if I am not wrong) environment to emulate a booted environment. Other than this, the kernel used by WSL2 is a custom, Microsoft-tailored LTS version which may cause some problems if some program rely on very new syscalls.

People are voting me down but it’s mostly from misinformation. WSL runs standard Linux distributions, it’s the real deal, not an imitation or anything that could be considered bad. If you face issues with it it’s mostly because of a fundamental misunderstanding of the setup (for example the person trying to run systemd…), not because it isn’t a „real Linux“.

I am waiting for two things; Better DE UX and graphics card sharing for VMs in consumer cards before I move full time to Linux.

Gnome 41 looks compelling and by the time consumer cards can be shared with VMs (for gaming, VR and that sort of thing), it might be as good as MacOS's desktop environment.

I can't wait to ditch Windows full time. It's such a confused mess of an OS.

DeathArrow13• 5 years ago

I used Linux since 2000. While I made countless tries to make it usable as a desktop, I had been forced to recognize long time ago that for me it isn't a good enough experience.

It alway needed lots of time to configure things to make it half decent, the configuration would broke from time to time. Some software which I want to use either runs poorly using Wine, either can't be run at all.

I am much more comfortable using Windows as a desktop and WSL has eliminated the need to dual boot or use a Linux VM.

I've been using xfce for about 10 years, and recently I've stopped customising it. I don't care about the theme, backgrounds etc. All I do is configured a single panel on the top of the screen and install plank. I have a few keyboard shortcuts for window tiling, and that's it. I haven't used Windows in a long time, so I'll be honest and say "I don't know what I'm missing", but I'm willing to bet that it ain't much, especially in return for what I get out of Linux. Maybe I should give it a go?

pjmlp10• 5 years ago

The real thing still has lots of issues, specially on laptops.

Using Linux distributions since 1995.

And I really don't get WSL, other than Windows trying to cater to the macOS crowd.

I have been using VMWare since 2010, when I need Linux on the laptop and have never felt I need something else.

For me the only thing I would get from WSL is not having to fight with IT for VMWare licenses.

zerocount• 5 years ago

I agree. I use seperate computers for each operating system I use; which is currently Windows 10 and FreeBSD. I don't use MacOS much any more and Linux seemed to be edging closer towards Windows, so FreeBSD brought me back into a more traditional Unix world with TWM and command lines. I enjoy it.

beowulfey2• 5 years ago

If you don’t like Fedora, perhaps try a different distro. Fedora’s commitment to free and open software has the downside of making proprietary hardware less reliable. From my own experience I would recommend Ubuntu or Manjaro. Those break rarely, if ever.

It is hard to characterize linux distros in broad terms because they all take such different approaches — two could be as similar as Windows 10 vs 8, or as different as Windows vs Mac!

cesarb2• 5 years ago

You might be thinking of UMSDOS. It was pretty neat; it allowed for instance C:\LINUX on DOS to become the root filesystem when booted into Linux (which also booted from DOS through LOADLIN), with the DOS root directory (C:\) becoming something else within Linux (I don't recall the exact path, it probably was something like /dos or /umsdos). That allowed you to install Linux like any other normal DOS program (yes, it was normal under DOS for a program to completely bypass the operating system), without having to re-partition/reformat or even change the bootloader. It's the main reason that I ended up using Linux and not one of the BSDs; I could try out Linux without any permanent changes to the current MS-DOS install (and some time later, I noticed that I was nearly all the time running Linux instead of DOS, so I re-partitioned to give Linux a whole ext2 partition).

I think WSL3, or should we call it USL from UNIX subsystem for Windows, should be a POSIX layer on top of the NT kernel. That way we should have better performance and better integration.

WSL1 was an implementation of Linux syscalls on top of NT.

They redesigned it as a VM (WSL2) because of compatibility and performance issues.

I have to wonder: if, as a user, one of your primary concerns is the WSL performance on Windows, what’s stopping you from just running Linux? Or at the very least simply dual boot for the cases where you truly do need something Windows exclusive, which these days seems to be less and less?
