Proton provides a better Windows runtime than Windows itself nowadays. Many games using legacy DirectX versions run perfectly fine on Linux, but need patches on Windows 11.

I study kernels for fun, so I've had a lot of opinions like that over the years, but none survived gaining more experience. For example, I used to think that the Windows NT kernel was a microkernel, then I thought that it was a hybrid, but now I know that it's actually monolithic. Likewise, I now understand that the major differences between the FreeBSD and DragonFlyBSD kernel are really just a few hundred lines of code, nothing major. But if you Google it, it'll make it sound like they're worlds apart.

Part of this is understanding that what people call "the kernel" usually includes a lot of things that, arguably shouldn't be considered part of the kernel proper. And a lot of the differences people cite between kernels come down to different message-passing architectures that are extremely interesting academically, but don't show up in real-world testing.

The sad part is, you can't reach this level of understanding though normal means, every source of information is full of half-truths. You have to dig into the source code and run these things on a bench yourself.

The difficult part is replicating the ecosystem of applications. From a technological standpoint I would prefer a modern Linux distribution with KDE or Cinnamon over using 2005-era Mac OS X Tiger, though I’d gladly use a version of Tiger that was retrofitted with a modern Darwin core, modern libraries for security purposes, and an up-to-date web browser. However, Linux does not have Microsoft Office, the Adobe Creative Suite, Preview.app, Keynote, Dictionary.app, and other pleasant Mac apps. The FOSS alternatives are not as polished. Even venerable Office 2008 for Mac feels nicer than LibreOffice, and it’s compatible with the XML-based Office formats.

I guess for now I could run Tiger in an emulator, though admittedly current operating systems serve my needs, even if I prefer the polish of Tiger and Snow Leopard. I get really good performance running PowerPC Tiger inside QEMU on my base M4 Mac Mini and on my Ryzen 9 3900 desktop, definitely not as snappy as running Tiger on actual contemporary PowerPC hardware, but fast enough to actually be productive.

Thankfully, macOS Golden Gate is proving to be a decent release so far in my tests of the public betas, but I do yearn for the simplicity (and more power user friendly aspects) of the aforementioned OS X releases.

Just FYI, the https://www.darlinghq.org project is doing MacOS app compat on Linux - i.e. building the userland libraries.

And with Apple, they’ve always approached the market as a hardware company first and foremost. Which is why macOS has always been free vs Windows which, until recently, was not.

Platforms like Linux was always a greater threat to both companies because Linux takes potential customers away from Microsoft and Apples ecosystems in ways that FOSS reimplementations do not.

But that all said, companies of that scale are inherently greedy and paranoid. So I wouldn’t be surprised to them burying those projects under a mountain of frivolous legal demands if those projects were to become as widely known as Linux.

> The format is very simple: it adds some accounting info at the start of the file, and then appends all the ELF binaries after it, adding padding for alignment. The end of the file isn't touched, so you can still do things like self-extracting .zip files for multiple architectures with FatELF.

But I would indeed call it very-not-alive; their demo image is Ubuntu 9.04

> The problem was Darwin was a marketing ploy, and nothing more. Marketing thought that by throwing some source files over the wall, they could increase their market share and revenue. And they were right. You go to almost any technical conference these days, and there is an astonishing number of Mac laptops in the crowd. Prior to Mac OS X, people would have been laughed out of the building for having a Mac, but now, with Mac OS X and the magic of open source, it was suddenly OK or even cool. Managerially and culturally, Apple had no intention of becoming involved with any community outside its own walls. There were some well intentioned engineers and even a few low level managers that were duped by their own marketing department, and that was all. These people had given substantial amounts of their free time under the illusion they were doing something Right, something Good, but in the end were simply used by their own company's marketing department.
