Not the device we need, but the one we deserve.


/dev/cyber uses a bleeding-edge architecture and state-of-the-art technologies to provide you with the following features (all benchmarks have been done on a Purism Librem 13):

  • High throughput access to CYBERspace
    • Up to 6.66 Gibibyte per second read speed
    • Up to 12 Gibibyte per second write speed
  • Unlimited storage
    • Uses brand spanking new Condensed Di-hydrogen-monoxide Numbering (CDN) storage.
    • Typically requires only 4kB of plain old RAM to instantiate CYBERspace
    • Does not require Internet connectivity
  • NSA-level security
    • Real-Time Flux Masking (RTFM) provides secure privilege separation
    • An average of 32768-Bit CYBERSpace Splitting (CSS) encoding to protect your data
  • High Availability through Inverse Nodal Tachyon Equilibrium Layering (INTEL)
  • Ultra low power consumption through Virtual Xenotropic (VX) scheduling
  • Minute system impact thanks to Correlative Cloud Compression (CCC)


From Source

Building and installing /dev/cyber is extremely easy! Follow these steps to CYBER-enable your system today:

  1. Acquire the source code via Generative Integration Traversal (GIT):

    $ git clone
  2. Enter the newly created directory using Coupling Demodulation (CD):

    $ cd dev-cyber
  3. Build the module with Magnetic Amplitude Knocking Extraction (MAKE):

    $ make
  4. Load the module through Systematic Unity Dissolution Orchestration combined with Instant Naturalistic System MODification (SUDO INSMOD):

    $ sudo -E make install
  5. PROFIT! (through unlimited CYBER)

Distribution Packages

Arch Linux

/dev/cyber is available in the AUR. Just use your favorite AUR package installer to install cyber-dkms and get CYBER-ified!

Using /dev/cyber

/dev/cyber is just as easy to use as all your other favorite devices like /dev/zero or /dev/random. (Although it is MUCH more secure!) The following examples will give you an example on how to use /dev/cyber for maximum effect.

Transferring backups into CYBERspace

Oftentimes, especially in big server systems, backups take up a lot of physical (e.g NON-CYBER) space. Instead of tediously moving old data to other locations via the net or physical media, /dev/cyber provides you with a much faster and way more SECURE alternative:

$ tar cf - /your_backup_storage_location > /dev/cyber

Transferring your backups to CYBERspace is fast and easy!

Seeding random number generators

You have probably heard of numerous issues concerning initialization of secure random number generators. What if /dev/random just has bad entropy? Fear no more! /dev/cyber supports CYBERSpace Splitting, a state-of-the-art Entropy Sourcing Mechanism (ESM). By simply reading all your entropy from /dev/cyber, you are guaranteed to never run out of first-class randomness!


As is the case with all good Linux kernel modules, /dev/cyber exports statistics and configuration information via the Stabilized Yarn Segregation Flash Structure (SYSFS). To view the currently used storage technology or the amount of CYBER available at the moment, you can use these commands:

# Check how much CYBER is available
$ cat /sys/class/cyber/available

# Check wich storage technology is being used at the moment
$ cat /sys/class/cyber/storage_technology


This project is the result of all the pain induced by all the "cyber"-thingamajigging and buzzword-flinging that is going on in the media (even specialist media) these days. If you want to contribute to a CYBER-free world consider one or more of the following options:

  • Stop using the word/prefix CYBER!
    • Tell your friends to stop too!
    • Tell you colleagues to stop also!
    • Ban it from your company!
  • Spread the word about this module. It would be great if we could manage to convince people to actually use it. Maybe they will stop CYBERing around when they have lost their data to CYBER space!
  • Implement new features!
    • Having a block device would be really cool!
    • Asynchronous I/O would also rock!
  • Improve this README
    • Add more examples!
    • Fix typos (VIM kinda sucks at highlighting typos in already highlighted text)!
    • CYBER it up even more!
  • Or at least, buy me a beer (technically does not fight CYBER, but it helps alleviate the pain) using BTC or LTC
    • BTC address (because github...): 17UjLY7p9hKHJZ7XJKFrNoUyNkDEtPMdSV
    • LTC address (because github...): LLi8TSBbwAoeigS4SuzBwa8hcYDkBDxutW


I have looked through the code a couple of times, but this is my first-ever Linux kernel module. It should be fine, since it pretty much is little more than /dev/zero (just with CYBER). You and your system should be fine but I cannot guarantee it!
