Sorry, dumb question. :) I guess I never noticed a problem because either I mostly use ext3/4, or I am so used to using legally dubious drivers that I forgot they were there. I mean, who ever gives you a FAT formatted disk? I don't have floppy drive anyway :p

Cameras. High capacity removable flash media used by digital still and video cameras is often formatted as exFAT. Despite MS' licensing, FAT/FAT32/exFAT are essentially the "file systems of interchange" for removable flash media. More info at: https://fossbytes.com/fat32-vs-ntfs-vs-exfat-difference-thre...

The SDXC standard (SD cards > 32GiB) specifies exFAT as the standardised Filesystem.

.... on FAT partitions

Linux itself creates a FAT partition for /boot, because the UEFI standard supports loading from FAT.

As well, if you ever look at a live-CD (like the installers for most modern Linux distros are), it will usually be using SYSLINUX, which limits itself to 8.3 filenames, for various good reasons to do with floppies, PXE, and ISO9660. Mount an Ubuntu CD in Windows and you'll see them.

What defines a "Linux-based system"? Does Android count? Would VMWare's VSphere ESXi hypervisor count? Would a unikernel running on a pared-down Linux rump-kernel (if such a thing were made) count?

According to http://en.swpat.org/wiki/GPLv2_and_patents , GPLv2 includes an implicit patent grant So my guess would be that the definition of "derivative work" would apply.

So the code in the linux kernel would have to be signed off/committed by MS in that case, right ? For a grant to have any meaning, the code would need to come from them ?

So after abusing this bullshit for more than a decade to bully companies. How gracious and generous of them. Oh btw, Satya is the CEO for 5 years.

Almost every months Microsoft make a more or less major gift to the open source community, this is beautiful. They are the new "benevolent" Google and it's no surprise they're now the number one open source contributor of the world.

Sure sure, They had been extorting countless companies for decades including Satya's 5 years. Give me a break. They are neither benevolent nor better than Google.

OMG, I can't believe we finally have a cross platform read/write disk format. At last. No more Fuse. I just need to know when it will be available for my Raspberry Pi.

Within the constraints of the technology (e.g. >2GB files) isn't FAT32 already this? I can plug it into my Apple, Windows, and Linux devices and it will just work.

That’s great but there’s nothing benevolent in their intentions. I don’t mean that as a slight, they’re the same as any other corporation - driven by profit and growth, not benevolence.

The difference is Microsoft sells and licenses products to help customers with real needs. Google's customers are all about dark marketing.

I think that's pretty unfair - Microsoft has changed enormously in the past 5 years.

Any news on NTFS ?

NTFS-3g is pretty good and support on Linux is definitely a lot better than it used to be. Still, official (or officially supported/documented) support would be really nice. Honestly I hope even Windows abandons NTFS soon. It's the worst part of using Windows. e.g. Try and develop any Node project on Windows and it's painful - takes literally minutes to delete the node_modules folder whereas on Linux/Mac it takes sec…

On the other side, file ACLs in NTFS are way more powerful than the Linux owner-group-world model.
