Interpretation of NTFS Timestamps

Interpretation of NTFS Timestamps” is a fascinating technical dive into the NTFS filesystem and the way it stores file and directory timestamps. Let me just leave you with this quote:

NTFS file timestamps, according to the documentation of the ‘FILETIME’ data structure in the Windows Software Development Toolkit, is a  “64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC)”.

WTF?

40x speed up of ls on large dirs

If you ever tried listing a directory with a lot (10,000+) of files in it, I’m sure you know how annoyingly slow ‘ls’ can be. Turns out there is a simple way to make it better. Have a look at the “When setting an environment variable gives you a 40x speedup” blog post.

Or just do the following:

export LS_COLORS='ex=00:su=00:sg=00:ca=00:'

This will disable colors on the executable files, setuid/setgid bits, and capabilities.

gitfs – version controlled file system


This was only a matter of time … gitfs – version controlled file system:

gitfs was designed to bring the full powers of git to everyone, no matter how little they know about versioning. A user can mount any repository and all the his changes will be automatically converted into commits. gitfs will also expose the history of the branch you’re currently working on by simulating snapshots of every commit.

Here is a brief feature list:

  • Automatically commits changes: create, delete, update files and their metadata
  • Browse through working index and commit history
  • Merges with upstream by automatically accepting local changes
  • Caching commits reduces the memory footprint and speeds up navigation
  • Reduces the number of pushes by batching commits

πfs – the data-free filesystem!


πfs – the data-free filesystem!

πfs is a revolutionary new file system that, instead of wasting space storing your data on your hard drive, stores your data in π! You’ll never run out of space again – π holds every file that could possibly exist! They said 100% compression was impossible? You’re looking at it!
