Linux Filesystems

When you create a filesystem specifically for use on a Linux system, there are six main filesystems that you can choose from:

    btrfs: A newer, high-performance filesystem that supports files up to 16 exbibytes (EiB) in size and a total filesystem size of 16EiB. It also can perform its own form of Redundant Array of Inexpensive Disks (RAID) as well as logical volume management (LVM). It includes additional advanced features such as built-in snapshots for backup, improved fault tolerance, and data compression on the fly.
    eCryptfs: The Enterprise Cryptographic File System (eCryptfs) applies a POSIX-compliant encryption protocol to data before storing it on the device. This provides a layer of protection for data stored on the device. Only the operating system that created the filesystem can read data from it.
    ext3: Also called ext3fs, this is a descendant of the original Linux ext filesystem. It supports files up to 2 tebibytes (TiB), with a total filesystem size of 16 TiB. It supports journaling as well as faster startup and recovery.
    ext4: Also called ext4fs, it's the current version of the original Linux filesystem. It supports files up to 16 TiB, with a total filesystem size of 1 EiB. It also supports journaling and utilizes improved performance features.
    XFS: A 64-bit high-performance journaling filesystem created by Silicon Graphics in 1993 and ported to Linux in 2001. It supports filesystems up to 8 exbibytes.
    swap: The swap filesystem allows you to create virtual memory for your system using space on a physical drive. The system can then swap data out of normal memory into the swap space, providing a method of adding additional memory to your system. This is not intended for storing persistent data.

I have used BTRFS a lot, but i have never tested the snapshot thingy. In all my applications it has simply just worked

🧵En sak trommemotstanderne hopper bukk over, som gikk igjen i kveld: vi kan ikke plukke fra en meny når det kommer til frivillig arbeid.

Med en gang de som driver med frivillig arbeid mister eierskapet til det de driver med, så forsvinner de. Magien med frivillighet er at du får være med og styre.

Nå som bensinprisene skyter i været er det viktig å huske at pris og kvalitet alltid henger sammen.

Ny blir det sykt bra bensin å få kjøpt!

Linux community normally:

Linux community when someone says Windows is better:

Picture of a highly specialized unit called W.A.P.-Weaponized Assault Penguins is shown here, and they are heavily armed (they have flippers to carry them).

A study of social media content 18-24-year olds see in #Finland, #France and #Romania shows that algorithms overwhelmingly feed them right-wing political content - whether or not the users are interested.

Three country average for right wing content was 58% - in Finland, 67%!
