The length of file names in early Unix (utoronto.ca)
If you use Unix today, you can enjoy relatively long file names on more or less any filesystem that you care to name. But it wasn't always this way.

Bcachefs, Btrfs, EXT4, F2FS and XFS File-System Performance on Linux 6.15 (phoronix.com)
With the copy-on-write Bcachefs file-system considering its on-disk format now "soft frozen" and nearing the point of potentially removing the "EXPERIMENTAL" flag on it, a number of Phoronix readers have been requesting some fresh benchmarks of this open-source file-system. For your viewing pleasure today are some fresh benchmarks of Bcachefs and other file-systems atop the Linux 6.15 kernel being released as stable later this month. On the benchmarking block today are Bcachefs, Btrfs, EXT4, F2FS, and XFS in-tree file-systems.

The FAT12 File Truncation Bug (brutman.com)
A few weeks ago I was doing some research on the FAT12 and FAT16 filesystems in an attempt to improve my NetDrive code, and I found a bug that can lead to a perfectly valid file being truncated when you move from DOS 2.x to later versions of DOS.

Fsync() after open() is an elaborate no-op (despairlabs.com)
I have spent the last couple of years of my life trying to make sense of fsync() and bringing OpenZFS up to code. I’ve read a lot of horror stories about this apparently-simple syscall in that time, usually written by people who tried very hard to get it right but ended up losing data in different ways. I hesitate to say I enjoy reading these things, because they usually start with some catastrophic data loss situation and that’s just miserably unfair.

Time Trouble (os2museum.com)
Last Friday I had a moment of panic. While investigating why different run-time libraries might interpret file timestamps differently, I noticed that even Windows doesn’t always agree with itself. When was dos4gw.exe last modified, at 10:14 PM or 9:14 PM?

50 years in filesystems: 1974 – Die wunderbare Welt von Isotopp (koehntopp.info)
Progress is sometimes hard to see, especially when you have been part of it or otherwise lived through it. Often, it is easier to see if you compare modern educational material, and the problems discussed with older material. And then look for the research papers and sources that fueled the change.

How fast can you open 1000 files? (lemire.me)
Jarred Sumner, the main author of the Bun JavaScript engine, commented a few days ago on X that opening many files on macOS could be slow due to thread contention: “your $5,000 computer is only capable of opening 1 file at a time”.
