WSL, WSL2? Whine?

Sorry, I wasn't clear enough. I meant here in this forum, among hobby OS developers.

Project Update: I know I may seem indecisive, but this last week I have gone back and forth on what to develop. I soon decided a microkernel based OS named NexOS. It is my dream OS. It will try to be as fast as possible, stable, and secure. Some services, namely, object and driver management, will be in kernel mode to improve performance. This OS will be truly good!

Whatever you think is great, IS good if you make it good. There a Pros for a microkernel (ok there are Contras, too, but life isn't perfect.)

Now you need a kernel. I think you already mentioned it, but I forgot: Which architecture are you developing for? x86 32bit? or x86 64bit? Legacy BIOS or UEFI?

Currently, 32 bit and 64 bit x86. It will be booted with GRUB. I plan on making an EFI application soon also. I plan on porting it to either MIPS or PowerPC, or perhaps IA-64.

it's popular among me. despite I am not a fan of posix/unix, I think, for targetting ARM SBCs, where enthusiasts are already used to linux(only), it would be nice to provide familiar tools for them. at least CUI programs (because linux GUI "systems" are far behind the bearable for me ).

have you noticed as well? it's a pretty well discoverable truth over here, that the more we talk and plan, the less we do.

I would first like to say NexOS is going great. It will be released in several incremental releases. The first if these is out now! Basically, it is the base of the system. It has the following features:

Portable. It works on 32 bit and 64 bit x86, with plans to port to ARM.
Compiles clean. Most components have all warnings turned on (except the HAL), and it has no warnings! Plus, it compiles with -O3
It also has:
Paging, a video driver that can output a progress bar and let it be updated, physical memory allocator, SMP support, Local and IO APIC drivers, plus more!
Here is a screenshot:

Thanks for all your help through development!

That sounds good! Well done.

Thanks, @PeterX! The next release will contain multitasking, an ELF loader, IPC and all the tasking stuff. That might take a while.

NexOS 0.0.2 is out! This release adds many new features, including:
SMP Scheduling, Messaging, event management, an ELF loader, a user mode memory allocator, a hosted user space with API, user mode heap allocator, a user mod runtime library, and more! Please visit https://github.com/Nexware-Project/NexOS to see it. There are no new screenshots, as there are no visible changes, but the number of lines code has almost doubled!

This is still not my favorite indie/hobby OS (that is Managarm), but I know that (despite not much visual effect) there is some work behind the NexOS release. Well done!

Do already have planned what's next? I hope this question doesn't cause pressure...

Yes, I do. The scheduler works, but has some issues. I will fix those, and make it work better on more then two CPUs. Then, I will add a driver manager to manage bus enumeration, driver configuration, IRQ routing, DMA assignment, and so on. Then I will add an object management system. After that it will be a release.

Hello all,
NexOS 0.0.2 ended up being a pot of bugs. Yesterday, I found that it would triple fault of page fault with ease. So I am making a new release, 0.0.3, which is a bug fix release. Here is what it has:
Fixes a bug which causes triple fault when create and deleting a thread at the same time
ELF loader clears BSS section
Fixes deadlock in kernel heap code.
Can now work on systems with more then 2 CPUs, but can't use more then 2 CPUs.
The SysWait system call does nothing now, however, but I will fix it with time.

Hello all!
I would like to announce version 0.0.4 has been released which has several new features, including
Scheduler bug fixes,
and a Driver Manager which includes:
A Driver Database manager,
A I/O port security mechanism,
A PCI Host controller driver,
PCI IRQ Routing,
PCI BAR mapping,
MP Table parser,
and much more.
The next release will revise all of NexOS, with bugfixes, a memory manager rewrite, an object manager, driver manager fixes, and more.
Thanks for all you help through the development
