#Filesystems
Honestly it’s probably way better with alcohol. I just wanna see unnecessarily 3d animated filesystems. Instead we got employee surveillance 😢

Filesystem drivers in Rust Linux has a number of filesystems that can deal properly with a "merely damaged" (corrupted filesystem). A maliciously corrupted filesystem will have correct metadata checksums, and is much harder to detect. There is a qualitative difference.

Secure your coding agents with virtual filesystems and better document understanding.

Building safe AI coding agents requires solving two critical challenges: filesystem access control and handling unstructured documents. We've created a solution using AgentFS, LlamaParse, and @claudeai.

Technically speaking in UEFI, you can just sort of tell the firmware to go away and override all of the drivers it preinstalls for filesystems, partitions, and such. I think it would be cool to write a driver that just replaces all the standard stuff with Rust hardened versions.

Honestly networked filesystems are just a disaster that've failed to live up to their potential

(and DOS) originally used FAT filesystems, which don't account for the needs of Unix (although in the earlier days of Linux people did maintain an extension of FAT called UMSDOS with full Unix support, but it had various issues and is long gone now)

teach even things such as accessing their filesystems is disturbing for how much we’re dependent on tech and it’s why tech companies keep getting away with sketchy changes and no huge outrage! we’re just being spoonfed and being told to look away without understanding the power technology has! 3/4

New version of dir2uf2 released, with support for targeting MicroPython's ROMFS partition (you need to bring your own filesystem packed with `mpremote romfs --output romfs.bin build `) and also other arbitrary filesystems, such as FAT. Plus other fixes!

Release Version 0.1.0- The UF2 is Getting FAT · Gadgetoid/dir2uf2
This build includes a number of changes gathered from various experiments over the last year or so. Many of these changes are already used in production, or very close to being used, so I'm confide...

and filesystems designed for Windows do things in ways that Unix applications aren't necessarily set up to handle either—drivers can get around this to some extent but not to the extent that they can perfectly translate between these worlds, because they're just too different
December 9, 2025 at 1:10 AM
speaking in general, you just don't want to use software which expects certain filesystem behaviors on a filesystem that lacks them; there are certain features that are standard for filesystems in Unix environments (POSIX permissions, ACLs, POSIX symlinks) that Windows isn't designed to work with,
December 9, 2025 at 1:10 AM
exFAT isn't a solution to this either because it also doesn't have exact parity in features with ext4; in fact it has less overlap with ext4 because it's fairly light on features compared to most filesystems
December 9, 2025 at 1:10 AM
it's really hard to say how well anything in particular will work without looking at the speciifc software you're using; it's possible to write software that can work with both filesystems, or which just doesn't depend on anything filesyste-specific, but any particular application may not be

(but the "no concept at all of filesystems or how to use a shell prompt" thing has been a "zoomers are the new boomers" symptom for a while)
December 8, 2025 at 10:01 PM
I suspect it’s historic, and the fact that unix-like systems (on which Mac, Linux, even Android, albeit distantly) are based, can have pluggable filesystems, and so needed to adopt standards early. See POSIX filesystem standards, the Filesystem Hierarchy Standard etc.

It's common for filesystems, which S3 isn't.

I like mostly not thinking about filesystems.
December 8, 2025 at 1:23 AM
My vague memory is that the original sin here was intentional as a cache busting hack because of the problems with cache invalidation on some linux filesystems (I want to say JFS but might be remembering wrong) during readdirplus operations. you do a 'stat' during that and you could end up looping.

The main difference between #btrfs and other CoW filesystems is a btrfs filesystem on a physical array is absolutely guaranteed to eat itself at some point. No other filesystem can claim that
